Technical Field

The invention relates to the technical field of enameled wire production equipment, in particular to automatic threading equipment for an annealing device and the annealing device.

Background

In the production process of the enameled wire, annealing is an essential process, and after annealing treatment is carried out on a bare copper wire, the bare copper wire is processed into the enameled wire. The purpose of annealing is to reduce the hardness and residual stress of the bare copper wire, reduce the deformation and crack tendency of the bare copper wire, improve the cutting processability of the bare copper wire, stabilize the size of the bare copper wire, refine the grain of the bare copper wire, adjust the structure and eliminate the structure defect. At present, a commonly used annealing device in a bare copper wire production process is a tubular annealing furnace, and an annealing pipe is arranged in the tubular annealing furnace. When the annealing pipe is used to anneal the bare copper wire, the end of the bare copper wire needs to be inserted into the annealing pipe from one end and then to be pulled out from the other end. The traditional threading method is that a steel strand is used to pass through one end of an annealing pipe, a strand head is manually pushed to the other end at the threading end, then a bare copper wire is bound at the tail of the steel strand, and the steel strand is manually pulled from the head to drive the bare copper wire to pass through the annealing furnace pipe. In the threading process, because the steel strand is long, the temperature in the annealing furnace is very high, whiplash and scalding are easily caused in the pulling process, and scalding accidents occur.

Disclosure of Invention

A first object of the present invention is to provide an automatic threading device capable of preventing scalding during threading of bare copper wires.

The second purpose of the invention is to provide an annealing device applying the automatic threading equipment.

In order to achieve the first purpose, the automatic threading equipment provided by the invention comprises a shell main body, a functional part and a fastener which are sequentially connected, wherein the shell main body comprises a first main body and a second main body which are mutually communicated, a first through hole is formed in the axial direction of the first main body, an air inlet hole is formed in the second main body, and the axis of the first through hole is vertical to the axis of the air inlet hole; the first through hole comprises a first communicating section and a second communicating section, the first end of the second communicating section is communicated with the first communicating section, the fastener is fixed on the second end of the second communicating section, a third through hole is formed in the axial direction of the fastener, and the third through hole is communicated with the second communicating section; the functional piece is arranged inside the second communicating section, a second through hole communicated with the first communicating section is formed in the axial direction of the functional piece, an annular groove is formed in the outer peripheral wall of the functional piece, and the annular groove is communicated with the air inlet hole; and the functional part is provided with an air outlet communicated with the ring groove, the air outlet is communicated with the second through hole, and the air outlet outputs airflow from the ring groove to the inner part of the second through hole.

According to the scheme, when the automatic threading equipment is used for threading, firstly, the bare copper wire is stretched into the automatic threading equipment from the first through hole, the bare copper wire is stretched into the second through hole in the functional part, and then gas is introduced into the gas inlet. The gas enters from the gas inlet hole, flows through the annular groove and then flows to the inside of the second through hole from the gas outlet hole. After the gas flows into the inner part of the second through hole, the air flow rate in the second through hole is accelerated, and the pressure is smaller as the gas flow rate is higher, and the air flow rate block is formed in the inner part of the second through hole due to the input of the external gas; the first communicating section is internally provided with no external gas, the air flow rate is low, and therefore the air pressure in the first communicating section is greater than the air pressure in the second through hole, a pressure difference is generated between the first communicating section and the second through hole, the bare copper wire penetrates out of the fastener from the inner part of the second through hole through the third through hole under the action of the pressure difference, and automatic threading is realized.

Preferably, the functional element comprises a first connecting section and a second connecting section which are connected, the first connecting section abuts against the end face of the first connecting section, and the second connecting section abuts against the end face of the fastening element.

The third communicating section is arranged in the axial direction of the first connecting section, the fourth communicating section is arranged in the axial direction of the second connecting section, and the second through hole comprises the third communicating section and the fourth communicating section.

The further scheme is that the air outlet holes are formed in the end face of the second connecting section, the number of the air outlet holes is more than two, and the air outlet holes are evenly formed in the circumferential direction of the end face of the second connecting section.

In a further scheme, the air outlet hole is communicated with the fourth communication section, and the air outlet hole extends from the annular groove to the center line of the fourth communication section.

In the above scheme, the venthole evenly sets up along the circumference of the terminal surface of second linkage segment, like this when high velocity air jets into fourth intercommunication section inside from the venthole, can guarantee that each position of fourth intercommunication section inside can both have high velocity air to jet into to play better acceleration effect to the inside air of fourth intercommunication section. If the air outlet holes are arranged along the circumferential direction of the end face of the second connecting section and are arranged unevenly, when high-speed airflow is injected into the fourth connecting section from the air outlet holes, the inflow of the high-speed airflow at certain positions is large, and the air velocity at the positions is high; the high-speed airflow inflow amount of some parts is small, and the air flow speed of the parts is slow. The phenomenon that the air flow rate in the fourth communicating section is uneven can occur, so that the air in the fourth communicating section is turbulent, and the accelerating effect on the air in the fourth communicating section is influenced.

According to a further scheme, an included angle between the air outlet direction of the air outlet hole and the axis of the second through hole is an acute angle, and the air outlet direction of the air outlet hole points to the center line of the second through hole.

In the above scheme, the contained angle of the direction of giving vent to anger of venthole and the axis of second through-hole is the acute angle, can guarantee like this that high-speed air current can shoot the central line department of second through-hole when the venthole jets out to can be full of the second through-hole better inside, reach better acceleration effect to the inside air of second through-hole. If the axis of venthole and the axis in the second through-hole are parallel, then when high air current jets out from the venthole, can't input central line department, high-speed air current can't be full of the inside of second through-hole effectively like this, influences the effect with higher speed to the inside air of second through-hole to make unable atmospheric pressure difference that produces between first communicating section and the second through-hole, lead to the naked copper line can't wear out from the second through-hole, influence automatic threading effect.

In a further scheme, the included angle between the air outlet direction of the air outlet hole and the axis of the second through hole ranges from 30 degrees to 45 degrees.

In the above scheme, the included angle between the air outlet direction of the air outlet hole and the axis of the second through hole ranges from 30 degrees to 45 degrees, if the included angle between the air outlet direction of the air outlet hole and the axis of the second through hole is too small, a longer distance needs to be reserved to reach the center line in the second through hole when the air is injected into the second through hole along the direction of the air outlet hole, and the actual use of the automatic threading device is not facilitated; if the contained angle value of the direction of giving vent to anger of venthole and the axis of second through-hole is too big, can increase the processing degree of difficulty of venthole itself, the high-speed air current that jets out simultaneously from the venthole can not be full of the inside of second through-hole well, just also can not play acceleration effect to the air in the second through-hole well. When the included angle between the air outlet direction of the air outlet hole and the axis of the second through hole is in the range of 30-45 degrees, on one hand, the processing of the air outlet hole is facilitated; on the other hand, when the high-speed airflow enters the second through hole along the range with the included angle of 30-45 degrees with the axial direction of the second through hole, the central line can be reached only by a short distance, meanwhile, the high-speed airflow can be well filled in the second through hole, and a good acceleration effect is achieved for the air in the second through hole. Therefore, the selection of the angle range is most suitable for the actual requirements of the user.

In a further scheme, the first main body is a circular tube, the second main body is a square block, and the air inlet hole is formed in the side wall of the square block.

Further, the second end of the second communication section is provided with an internal thread, the end part of the fastening piece is provided with an external thread, and the fastening piece is in threaded connection with the internal thread through the external thread.

In order to achieve the second object, the annealing device provided by the invention comprises the automatic threading equipment, and the annealing device comprises an annealing device body, wherein an annealing pipe is arranged in the annealing device body, and the annealing pipe is communicated with the first main body.

According to the scheme, in the process of annealing the bare copper wire by using the annealing device, the bare copper wire is firstly stretched into the annealing pipe from one end of the annealing pipe, then air flow is introduced into the air inlet hole, when the bare copper wire penetrates out of the annealing pipe from the other end of the annealing pipe, air is stopped from being introduced into the air inlet hole, then the rest bare copper wire is slowly stretched into the annealing pipe, and annealing treatment is carried out on the bare copper wire. In the process of introducing air flow to the air inlet hole, the high-speed air flow can blow the waste wire in the annealing pipe out of the annealing pipe, so that the waste wire is prevented from influencing the production of the enameled wire.

Detailed Description

Automatic threading device embodiment:

referring to fig. 1 to 3 and 5, the automatic threading device provided in this embodiment includes a housing main body 1, a functional member 2, and a fastening member 3 connected in this order. The housing body 1 comprises a first body 11 and a second body 12 which are mutually communicated, a first through hole 13 is formed in the axial direction of the first body 11, an air inlet hole 14 is formed in the second body 12, and the axes of the first through hole 13 and the air inlet hole 14 are vertical. The first through hole 13 includes a first communicating section 131 and a second communicating section 132, and a first end of the second communicating section 132 communicates with the first communicating section 131. The fastening member 3 is fixed to the second end of the second communicating section 132, a third through hole 31 is opened in the axial direction of the fastening member 3, and the third through hole 31 is communicated with the second communicating section 132.

In the present embodiment, the functional element 2 is disposed inside the second communicating section 132, and a second through hole communicated with the first communicating section 131 is opened in the axial direction of the functional element 2. The functional element 2 comprises a first connecting section 21 and a second connecting section 22 which are connected, the first connecting section 21 and the first connecting section 22 being delimited by a dashed line 15 in fig. 3. The first connecting section 21 abuts on an end face of the first communicating section 131, and the second connecting section 22 abuts on an end face of the fastening member 3. A third communicating section 211 is arranged along the axial direction of the first connecting section 21, a fourth communicating section 221 is arranged along the axial direction of the second connecting section 22, and the second through hole comprises the third communicating section 211 and the fourth communicating section 221. An annular groove 23 is formed in the outer peripheral wall of the functional part 2, and the annular groove 23 is communicated with the air inlet hole 14. The functional part 2 is provided with an air outlet 24 communicated with the annular groove 23, the air outlet 24 is communicated with the fourth communication section 221, and the air outlet 24 outputs air flow from the annular groove 23 to the inside of the fourth communication section 221.

In this embodiment, the first body 11 is a circular tube, the second body 12 is a square block, and the air inlet 14 is formed on a side wall of the square block. An internal thread 133 is provided at a second end of the second communicating section 132, an external thread 32 is provided at an end of the fastening member 3, and the fastening member 3 is threadedly coupled with the internal thread 133 through the external thread 32.

Referring to fig. 3 and 4, the air outlet holes 24 are provided on the end surface of the second connecting section 22, the number of the air outlet holes 24 is two or more, and the air outlet holes 24 are uniformly provided along the circumferential direction of the end surface of the second connecting section 22. In fig. 4, the number of the air outlet holes 24 is four, and the central angle formed by every two adjacent air outlet holes 24 is 90 °, wherein one air outlet hole 24 is not shown in the figure. The number of the air outlet holes 24 can also be three, the three air outlet holes 24 are uniformly arranged on the end surface of the second connecting section 22 along the circumferential direction, and the central angle formed by every two adjacent air outlet holes 24 is 120 degrees.

Referring to fig. 2 and 3, when the automatic threading device is used for threading, firstly, a bare copper wire is inserted into the first through hole 13, the bare copper wire is inserted into the second through hole in the functional part 2, and then gas is introduced into the gas inlet hole 14. The gas enters from the gas inlet hole 14, flows through the ring groove 23, and then flows from the gas outlet hole 24 to the inside of the fourth communication section 221. When the gas flows into the fourth communicating section 221, the air flow rate in the fourth communicating section 221 is increased, the pressure is reduced as the gas flow rate is higher, and the air flow rate is high as the external gas is input into the fourth communicating section 221; no outside air is input into the third communicating section 211, the air flow rate is slow, so that the air pressure in the third communicating section 211 is larger than the air pressure in the fourth communicating section 221, a pressure difference is generated between the third communicating section 211 and the fourth communicating section 221, and under the action of the pressure difference, the bare copper wires penetrate out of the fastener 3 from the inner part of the second through hole through the third through hole 31, so that automatic threading is realized.

Referring to fig. 2 to 4, the air outlet holes 24 are uniformly arranged along the circumferential direction of the end surface of the second connecting section 22, so that when high-speed air is injected into the fourth communicating section 221 from the air outlet holes 24, it can be ensured that high-speed air can be injected into each part inside the fourth communicating section 221, and thus, a better acceleration effect is achieved on the air inside the fourth communicating section 221. If the arrangement is uneven when the air outlet holes 24 are arranged along the circumferential direction of the end surface of the second connecting section 22, when the high-speed airflow is injected into the fourth communicating section 221 from the air outlet holes 24, the inflow amount of the high-speed airflow at some parts is large, and the air velocity at these parts is high; the high-speed airflow inflow amount of some parts is small, and the air flow speed of the parts is slow. This causes the uneven flow rate of air in the fourth communicating section 221, which results in the turbulent flow of air in the fourth communicating section 221, and affects the acceleration effect of air in the fourth communicating section 221.

Referring to fig. 2 and 3, the direction indicated by the arrow in fig. 3 is the air outlet direction of the air outlet hole 24. The included angle between the air outlet direction of the air outlet hole 24 and the axis of the second through hole is an acute angle, the included angle ranges from 30 degrees to 45 degrees, and the air outlet direction of the air outlet hole 24 points to the central line of the fourth communication section 221. The included angle between the air outlet direction of the air outlet hole 24 and the axis of the fourth communicating section 221 is an acute angle, so that the high-speed air flow can be ensured to be emitted to the center line of the fourth communicating section 221 along the direction indicated by the arrow in fig. 3, the inside of the fourth communicating section 221 can be filled with the air better, and the air in the fourth communicating section 221 can be accelerated better. If the air outlet direction of the air outlet hole 24 is parallel to the axis of the fourth communicating section 221, then when the high-speed airflow is emitted from the air outlet hole 24, the high-speed airflow cannot be input to the center line of the fourth communicating section 221, so that the high-speed airflow cannot be effectively filled in the fourth communicating section 221, the acceleration effect on the air in the fourth communicating section 221 is influenced, the air pressure difference cannot be generated between the third communicating section 211 and the fourth communicating section 221, the bare copper wire cannot penetrate out of the second through hole, and the automatic threading effect is influenced.

In this embodiment, the angle between the outlet direction of the outlet hole 24 and the axis of the fourth communicating section 221 is in the range of 30 ° to 45 °. The reason why the above range is selected is that, as can be seen from fig. 3, the air outlet hole 24 is formed between the side wall 222 of the second connecting section 22 and the blocking wall 223, if the angle between the air outlet direction of the air outlet hole 24 and the axis of the fourth communicating section 221 is too large, the difficulty in processing the side wall 222 and the blocking wall 223 is increased, and the processing cost of the functional component 2 itself is increased. Meanwhile, the high-speed airflow emitted from the air outlet 24 does not fill the inside of the fourth communicating section 221 well, and thus does not accelerate the air in the fourth communicating section 221 well. If the angle between the air outlet direction of the air outlet hole 24 and the axis of the fourth communicating section 221 is too small, when the air is injected into the fourth communicating section 221 along the direction of the air outlet hole 24, a longer distance needs to be reserved to reach the center line of the fourth communicating section 221, so that the length of the fourth communicating section 221 needs to be increased, and the practical use of the automatic threading device is not facilitated. When the included angle between the air outlet direction of the air outlet hole 24 and the axis of the fourth communicating section 221 is in the range of 30 degrees to 45 degrees, the center line of the fourth communicating section 221 can be reached only by a short distance, meanwhile, the high-speed air flow can be well filled in the fourth communicating section 221, and a good acceleration effect is achieved on the air in the fourth communicating section 221. Therefore, the selection of the angle range is most suitable for the actual requirements of the user.

Referring to fig. 6, the air outlet holes 24 in fig. 3 are straight holes, the air outlet holes 25 in fig. 6 are bent holes, and the direction indicated by the arrow in fig. 6 is the air outlet direction of the air outlet holes 25. As long as the air outlet direction of the air outlet hole 25 satisfies the above range, the high-speed air flow emitted from the air outlet hole 25 can also exert a good acceleration effect on the air inside the fourth communication section 224. Therefore, the air outlet holes can be straight holes or bent holes, are not limited to a specific shape, and only need to meet the requirement that the included angle between the air outlet direction of the air outlet holes and the axis of the fourth communication section is in the range of 30-45 degrees.

In this embodiment, the inner diameter of the first through hole 13 ranges from 2 cm to 3cm, and the pressure of the compressed air introduced from the air inlet hole 14 is 0.1 MPa.

Annealing apparatus embodiment:

the annealing device that this embodiment provided includes above-mentioned automatic threading equipment, and annealing device includes the annealing device body, is provided with annealing pipe in the inside annealing device body, and annealing pipe and first main part are linked together.

In this embodiment, the temperature in the annealing tube is 400 to 500 ℃. In the process of annealing the bare copper wire by using the annealing device, firstly, the bare copper wire is stretched into the annealing pipe from one end of the annealing pipe, then air flow is introduced into the air inlet, when the bare copper wire penetrates out from the other end of the annealing pipe, air is stopped from being introduced into the air inlet, and then the rest bare copper wire is slowly and continuously stretched into the annealing pipe to anneal the bare copper wire. In the process of introducing air flow to the air inlet hole, the high-speed air flow can blow the waste wire in the annealing pipe out of the annealing pipe, so that the waste wire is prevented from influencing the production of the enameled wire.

While the present invention has been particularly shown and described with reference to the present embodiments and preferred versions thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
