The last procedure of steel cord production is that a stranding machine twists the monofilaments (plated copper wires) produced by a wet drawing machine into steel cord strands (steel cords), and the steel cord strands are wound on a spool. Due to the equipment, the process, the monofilament raw materials and the like, the steel cord stranding machine can cause rope breakage in the stranding process to become a semi-finished product. And (3) as the semi-finished product does not reach the set required length, the semi-finished product needs to be sent to a recoiler for re-production, 2 or more rounds of semi-finished product steel cords are welded and connected by using a butt welding machine, and a take-up wire is wound on an I-shaped wheel to reach the set required length to form the finished product. The butt welding machine welds the steel cord by melting two ends to be welded by current and then connecting the two ends to complete welding. However, because the steel cord is melted and extruded, the outline diameter of the welding point becomes large and the shape is irregular. The use of a tire factory is influenced by the fact that the outside diameter of the welding spot exceeds the standard, and the wire can not be broken through the wire passing hole during paying off.

Detailed Description

In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.

Referring to fig. 1 to 4 in combination, the present invention provides a steel cord welding spot threading plate, as shown in fig. 1 to 3, the steel cord welding spot threading plate includes a hard alloy plate 1 and a 45# steel plate 2 welded up and down, the hard alloy plate 1 is located above the 45# steel plate 2, an L-shaped detection slot 3 is provided on the hard alloy plate 1, the detection slot 3 includes a vertical slot 31, an arc slot 32 and a horizontal slot 33, the vertical slot 31 includes a first end 311 and a second end 312 opposite to each other, the first end 311 is located on the edge of the hard alloy plate 1 not connected to the 45# steel plate 2, the second end 312 is connected to one end of the arc slot 32, the horizontal slot 33 includes a third end 331 and a fourth end 332 opposite to each other, the third end 331 is connected to one end of the arc slot 32 far from the second end 312, the vertical slot 31, the widths of the transverse grooves 33 and the circular arc grooves 32 are standard sizes of the welding point outlines of the steel cords to be detected.

When the steel cord welding spot wire passing plate is used for detecting the diameter of a welding spot, a detector holds a steel cord by hand to send a steel wire into the detection groove 3 from the top end of the vertical groove 31, the steel wire is firstly detected in the vertical groove 31 and then transited and moved downwards to the transverse groove 33 through the arc groove 32 to be detected, the steel cord moves downwards in the vertical groove 31 to detect whether two end points on the left side and the right side of the welding spot exceed the standard length or not, the welding spot of the steel cord enters the arc groove 32 from the vertical groove 31, the periphery of the welding spot of the steel cord, which is opposite to the arc edge of the arc groove 32, can be detected in sequence when the steel wire slides in the arc groove 32, and if the welding spot can pass, the diameters of the arc edges of the welding. The steel wire enters the transverse groove 33 after passing through the arc groove 32, and the steel wire moves left and right in the transverse groove 33 to check whether two end points on the upper side and the lower side of the welding point exceed the standard length. Therefore, the original L-shaped detection groove 3 is changed into the L-shaped detection groove, the middle corner is transited by the arc groove 32, whether the lengths of the diameters of the welding spots of the steel cord meet the standard or not can be detected, the detection method is simple and effective, the input cost of the filament passing plate is reduced, and the requirement for detecting the diameters of the welding spots of the cord is met.

In addition, the wire passing plate detection groove 3 is made of hard alloy, the other parts are made of 45# steel, the two parts are welded together, the hard alloy is high in hardness and good in wear resistance, severe wear cannot occur after long-term use, the test period of the detection groove 3 is prolonged, the workload of workers is reduced, and the condition that the accuracy of a measurement result is influenced due to the fact that the 45# steel plate 2 is used at present can be greatly reduced.

In one embodiment, the longitudinal section of the first end 311 is an isosceles trapezoid with a top surface length greater than a bottom edge length, i.e. the top opening diameter of the first end 311 is greater than the diameter of the vertical slot 31. The solder joint of steel cord can relatively easily get into from the opening part of first end 311 and detect groove 3 like this, prevents to detect the perpendicular groove 31 opening part undersize of groove 3 and makes the detection personnel can't aim at the first end 311 opening of perpendicular groove 31 in proper order, and the steel cord solder joint takes place the condition that friction leads to notch and steel cord all by the fish tail with notch department.

In another embodiment, the central angle of the circular arc groove 32 is 90 °, i.e. the vertical groove 31 and the horizontal groove 33 are perpendicular to each other. The vertical groove 31 and the transverse groove 33 are transited through the arc groove 32, the vertical groove 31 and the transverse groove 33 are perpendicular to each other, the arc groove 32 is 90 degrees, namely two ends of the arc groove 32 are respectively tangent to the vertical groove 31 and the transverse groove 33. As shown in fig. 4, when the welding point of the steel cord slides in the sensing groove 3, the diameter sensed in the vertical groove 31 is the diameter 41 in fig. 4, i.e. the diameter in the horizontal direction, after the welding spot of the steel cord enters the arc groove 32, in the process of sliding along the arc line, the detected welding spot diameter is also changed in a sounding way, in fig. 4, the weld diameters are taken as examples in two states, where diameter 42 is angled with respect to diameter 41, diameter 43 is angled with respect to diameter 41, and as the weld point slides down, the angle between diameter 43 and diameter 41 is greater than the angle between diameter 42 and diameter 41, the angle between the diameter 41 being measured from 0 to 90, and when 90 is reached, the welding point of the steel cord reaches the tangent point of the circular arc groove 32 and the transverse groove 33, and then the steel cord slides to enter the transverse groove 33, the present invention can seamlessly inspect all diameter lengths from diameter 41 to diameter 44 at the circular arc groove 32.

Preferably, the inside of the L-shaped detection groove 3 is smooth, and the transition between the vertical groove 31 and the circular arc groove 32 and between the horizontal groove 33 and the circular arc groove 32 is smooth. The welding points of the steel cord can conveniently slide in the detection groove 3 without obstacles, and the welding points can be prevented from moving due to other reasons except that the size of the welding points exceeds the standard, such as overlarge friction on the inner wall of the detection groove 3.

Preferably, neither the vertical slots 31 nor the transverse slots 33 are greater than 10 centimeters in length. Because both ends are all fixed when the solder joint of steel cord detects, the scope that the steel cord can move is limited to solder joint size detection does not need the solder joint to slide longer distance in same direction in the inslot, so restrict the length of vertical slot 31 and horizontal slot 33, be favorable to controlling the displacement distance of cord, make things convenient for the measurement personnel to detect.

Preferably, the length of the transverse slots 33 is less than the length of the vertical slots 31.

In another embodiment, the detection groove 3 is cut and machined using a slow wire cutting process. The slow wire cutting is one kind of wire cut electric discharge machining, and is mainly used in machining various complicated and precise workpieces. The slow-walking wire cutting processing technology can enable the precision of the detection groove 3 to reach +/-0.01 mm, particularly the diameter of a welding spot of the steel cord is small, the detection precision of the diameter of the welding spot is also high, the precision of +/-0.01 mm meets the use requirement, and the cost is reduced.

From the above, the detection groove shape of the welding spot detection wire passing plate is improved, the detection groove shape is changed into an L shape, and the corners are designed to be arc angles. When the staff detects the solder joint diameter, the cord thread position of holding does not need to rotate, detect at first in the vertical groove, move down the cross slot and detect again, vertical groove and cross slot can detect two points of the different diameters of steel cord thread solder joint, and the circular arc groove of corner makes the solder joint of steel cord thread along with sliding in the circular arc groove, and the diameter both ends in all directions all obtain detecting, and detection method is simple, effective, can satisfy the requirement of detecting many diameters of cord thread solder joint under the prerequisite that reduces silk screen input cost.

The detection groove of the wire passing plate is changed into a hard alloy material, so that the wear resistance is good, the wire passing plate cannot be seriously worn after being used for a long time, and the monitoring precision can be kept. The other parts still use 45# steel materials, and the two parts are welded together, so that the material cost is reduced, and the use requirement can be met.

The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the invention. Rather, it is intended that all such modifications and variations be included within the spirit and scope of this invention.
