Technical Field

The invention relates to the field of copper pipe milling, in particular to a casting blank pulling mechanism and a casting blank pulling system.

Background

In the copper processing industry, a cast blank surface drawn by casting can be oxidized, and the scale is milled off by a milling machine so as to carry out subsequent processes such as rolling, drawing and the like. Generally, a cast blank drawn by casting is stored on a tilted material storage table, the cast blank rolls onto a roller conveyor under the action of self gravity, and a feeding mechanism on the roller conveyor transports the cast blank to a machine table of a surface milling machine for milling surface scale.

In order to prevent excessive sliding of the blank onto the conveying roller way, a blank protecting mechanism is arranged at one end of the material storage table close to the conveying roller way, and specific arrangement scheme refers to fig. 1 and fig. 2, wherein fig. 1 is a schematic installation diagram of the casting protecting mechanism at the present stage; FIG. 2 is a schematic structural view of a casting protective mechanism at the present stage. As shown in fig. 1, one end of a material storage table 1 is connected with a casting blank traction mechanism 2, and the other end is connected with a conveying roller table 3 and is obliquely arranged towards one side of the conveying roller table; the casting blank protecting mechanism 4 is arranged below the connection part of the material storage table 1 and the conveying roller table 2. As shown in fig. 2, the casting blank protecting mechanism 4 comprises a support 41, a protecting cylinder 42, a rotating arm 43, a first blocking rod 44 and a second blocking rod 45; the support 41 is arranged on the conveying roller way and extends towards the material storage table, and a first guide sleeve and a second guide sleeve are arranged on the support 41 along the rolling direction of the cast blank; the protective air cylinder 42 is arranged on the outer side of the conveying roller way and is positioned below the bracket 41; the rotating arm 43 is coupled with the gear protection cylinder 42 through a connecting shaft; the first blocking rod 44 and the second blocking rod 45 are hinged to the rotating arm 43 through a first connecting rod and a second connecting rod, respectively, and the first blocking rod 44 and the second blocking rod 45 extend out of or retract into the first guide sleeve and the second guide sleeve under the driving of the blocking cylinder 42. Thus, the first blocking rods 44 and the second blocking rods 45 are alternately extended or retracted to block the rolled blank to controllably and orderly roll the blank onto the conveyer table.

However, the blank protection mechanism adopted at the present stage has the following problems: when the casting blank is bent or rolls from head to tail out of synchronization, the casting blank stays on the material storage table and cannot automatically roll off, and the material cannot be continuously fed to the surface milling machine. At this time, since the casting block mechanism cannot shift the stopped casting blank, an operator needs to buckle the casting blank stopped to roll by a tool and turn the casting blank onto a conveying roller way, the process of manually turning the casting blank is time-consuming and labor-consuming, the loading of the surface milling machine is delayed, and the pin milling efficiency of the surface milling machine is affected.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

Please refer to fig. 3, which is a schematic structural diagram of a cast billet mechanism according to an embodiment of the present invention.

As shown in the figure, the material storage table 10 is erected between the casting blank traction device 20 and the roll gang 30, a casting blank guard assembly 40 is arranged below the connection of the material storage table 10 and the roll gang 30, and a casting blank pulling mechanism 50 is arranged above the connection of the material storage table 10 and the roll gang 30. The cast blank pulling mechanism 50 is used for pulling a cast blank on the material storage table 10; the cast blank guard assembly 40 is used when the cast blank mechanism 50 fails, and can be blocked, so that the cast blank is prevented from rolling onto the conveying roller table 30 too much.

The casting blank pulling mechanism comprises a base 51 and a pulling machine 52; the base 51 comprises a base 511 and a cantilever 512 mounted on the base 511; the kick-out machine 52 is arranged on the cantilever 512 and is positioned above the material storage table; the kickoff 52 comprises a frame 521, a kickoff component 522 and a first blocking component 523, wherein the kickoff component 522 and the first blocking component 523 are installed on the frame 521; the pulling member 522 is in contact with a cast blank on the material storage station so as to pull the cast blank, and the first blocking member 523 is used for blocking the rolling of the cast blank. A cast blank drawn by casting is stored on a material storage table, when a material signal of a surface milling machine is received, a casting blank pulling mechanism pulls the cast blank to roll onto a conveying roller table through a pulling assembly 522, and in the process of rolling the cast blank, when a cast blank is rolled down, a first blocking assembly 523 timely extends downwards to block the subsequent cast blank which is not rolled down, so that the cast blank is orderly rolled onto the conveying roller table to wait for the material.

Specifically, the structure of the cast blank pulling mechanism is described in detail below.

The base 51 comprises a base 511 arranged on the outer side of the conveying roller way, and a cantilever support 513 is arranged above the base 511; the upper part of the cantilever support 513 is provided with an installation shaft, and the cantilever 512 is movably arranged on the installation shaft and can rotate up and down around the cantilever support 513; the cantilever 512 extends from the outer side of the roller conveyor in a direction towards the material storage station, and the blank puller 52 is located right above the cast blank.

For convenience of installation and maintenance, a kickoff positioning assembly 514 is further arranged on the base 51; the kickoff positioning component 514 comprises a positioning pin and a positioning hole which are matched with each other; the positioning pin is arranged at one end of the cantilever support 513 close to the base 511; the positioning hole is arranged on the outer wall of the upper end of the base 511; when the positioning pin is aligned with the positioning hole, the cast blank poking machine 52 is located right above one end, close to the conveying roller way, of the material storage table, so that the cast blank poking machine 52 is prevented from shaking in the material poking process.

Further, a cylinder mounting groove is further formed in the base 511, and a lifting cylinder 515 is mounted in the cylinder mounting groove; the cantilever support 513 is connected with a piston rod of the lifting cylinder 515, and the cantilever support 513 drives the cantilever 512 and the material poking machine 52 to ascend or descend under the driving of the lifting cylinder 515.

During installation, when the material puller 52 is located above a cast blank of the material storage table, a positioning pin is inserted into the positioning hole to ensure that the material puller can be located right above the cast blank so as to facilitate material pulling, and at this time, the lifting cylinder 515 is retracted to the original position; when the cast blank puller 52 needs to be serviced, the locating pin can be pulled out while the cantilever support 513 is lifted by the lifting cylinder 515 so that the cast blank puller principle is a blank on the material storage table, and the cast blank puller 52 is rotated to the outer side of the material storage table for convenient servicing. After the overhaul is completed, the cantilever support 513 is rotated to align the positioning pin with the positioning hole, the lifting cylinder 515 is retracted to the original position, and the positioning pin is inserted into the positioning hole, so that the casting blank drawing machine 52 is positioned.

In this embodiment, the material ejecting device 52 includes a frame 521, a material ejecting assembly 522 disposed on the frame 521, and a first blocking assembly 523.

The frame 521 is mounted on the cantilever 512 through a rotating shaft and is positioned above one end, close to the conveying roller way, of the material storage table; fixing bolts are respectively arranged on two sides of the rotating shaft on the cantilever 512; the fixing bolt tightly supports the frame of the kicking machine downwards. Before use, the frame 521 rotates through the rotating shaft to correct the position of the frame 521, so that the frame 521 is located right above one end of the material storage table close to the roller conveyor, and the blank pulling assembly can be perpendicular to the placing direction of the cast blank.

The kickoff assembly 522 is mounted to the frame 521 and is in contact with a blank on the material storage stand for pulling a blank. In this embodiment, the material pulling assembly 522 includes a driving motor, a driving wheel, a driven wheel, a belt and a pressing assembly mounted on the frame 521; the driving wheel is coupled with an output shaft of the driving motor; the belt is wound on the driving wheel and the driven wheel and is in contact with a cast blank on the material storage table; the pressing assembly is positioned between the driving wheel and the driven wheel and is pressed downwards to enable the belt to be in close contact with the cast blank; the driving motor drives the belt to transmit towards the direction of the conveying roller way through a driving wheel and a driven wheel, and the belt pulls the cast blank under the action of the pressing assembly.

In an alternative embodiment, the pressing assembly may be a flat roller assembly, which is mounted on the frame 521 by a screw. By adopting the flat roller assembly as the tensioning assembly of the belt, the belt can be in better contact with the cast blank, and the cast blank can be conveniently rolled downwards by pulling. The result of the compression assembly is not limited, and in other embodiments, other configurations may be used.

Further, the driving motor is a servo motor, and the servo motor can calculate the output quantity of the servo motor, so that the servo motor is used as the belt drive to accurately control the belt transmission distance.

The first blocking assembly 523 is installed on the frame 521 and located above the connection between the material storage station and the roller conveyor for cooperating with the pulling assembly to enable the blank to orderly and controllably roll on the roller conveyor. The first blocking assembly 523 comprises a first cylinder and a first positioning block; the first positioning block is connected with a piston rod of the first air cylinder; the first cylinder drives the first positioning block to extend or retract downwards. When the pulling assembly 522 rolls onto a conveying roller table by pulling, the first positioning block extends downwards under the pushing of the first cylinder to block the subsequent roll of the blank. The transmission distance of the belt can be accurately controlled through the driving pulse of the servo motor, when the transmission distance of the belt is the circumference length of a cast blank, the driving motor is controlled to stop rotating, and at the moment, the first positioning block extends downwards to be clamped at the connection position of the material storage table and the conveying roller way so as to prevent a subsequent second cast blank from rolling onto the conveying roller way. When the blank on the conveying roller way is conveyed forwards, the first cylinder retracts to drive the first positioning block to retract, and meanwhile, the servo motor operates to roll the next blank through shifting of the belt. Therefore, ordered and controllable roll-off of one blank is realized, and excessive roll-off of the blank onto a conveying roller way is effectively prevented.

Further, in order to prevent excessive casting blanks from rolling under the belt of the reclaimer 52, a second blocking assembly 524 is further provided on the frame 521 of the reclaimer 52. The second blocking component 524 is located above the middle part of the material storage table, and comprises a second cylinder and a second positioning block; the second positioning block is connected with a piston rod of the second cylinder; the second cylinder drives the second positioning block to extend or retract downwards so as to prevent the excessive cast blank from rolling to the lower side of the belt and prevent the stacking of the cast blank.

In an alternative embodiment, the cast stock mechanism further includes a cast stock guard assembly 40. The casting blank protective assembly 40 is arranged below the connection part of the material storage table and the conveying roller way; the casting base guard assembly 40 comprises a support, a guard cylinder, a rotating arm, a first blocking rod and a second blocking rod; the support is arranged on the conveying roller way and extends towards the material storage table, and a first guide sleeve and a second guide sleeve are arranged on the support along the rolling direction of the cast blank; the shield cylinder is arranged on the outer side of the conveying roller way and is positioned below the bracket; the rotating arm is coupled with the protective cylinder through a connecting shaft; the first blocking rod and the second blocking rod are hinged to the rotating arm through a first connecting rod and a second connecting rod respectively, and the first blocking rod and the second blocking rod are driven by the protective cylinder to extend out of or retract back into the first guide sleeve and the second guide sleeve respectively. When the material stirring machine on the casting blank stirring mechanism breaks down, the casting blank protecting assembly can be temporarily used for protecting the casting blank, so that the casting blank slides down to the conveying roller table under the action of self gravity, and in the sliding down process, the casting blank can be separated through the first blocking rod and the second blocking rod, so that the casting blanks can be orderly rolled down one by one. Therefore, when the material poking machine breaks down in time, continuous loading of the cast blank can be achieved, the surface milling machine can continuously mill the cast blank, and benefit loss caused by broken-down equipment is reduced.

In other embodiments, the cast material shifting mechanism may not include a cast guard assembly, and the structure of the cast guard assembly is not limited, and the structure of the original cast guard mechanism may be adopted, or other structures may be adopted.

In the process that the cast blank is transferred from the material storage table to the conveying roller way, because the material storage table is erected between the casting pulling mechanism and the conveying roller way and is inclined at a certain angle towards the conveying roller way, the cast blank rolls towards the conveying roller way under the action of self gravity. During the pulling process, the blank may have a bend or other topographical defect such that the blank may not roll off itself and the blank may remain on the material storage station. If the casting blank pulling mechanism in the embodiment is adopted, a certain power can be applied to the casting blank, so that the bent or abnormal casting blank can be rolled onto the conveying roller way.

Hereinafter, the principle of use of the blank pulling mechanism according to the embodiment will be described.

The driving motor of the blank poking machine drives the casting blank to roll through the transmission of the belt, the belt becomes tense when being pressed by the pressing flat roller, so that the friction between the belt and the casting blank is continuously increased, the casting blank is further driven to roll, when the driving motor drives the belt to drive the circumference of one casting blank to be long, the driving motor stops running, and the first blocking rod is pushed by the air cylinder to downwards extend out to be clamped at the connection position of the material storage table and the conveying roller way, so that the subsequent casting blank is prevented from continuously rolling. When the first cast blank rolled onto the conveying roller way is conveyed away, the driving motor continues to operate, the first blocking rod is retracted, and the second cast blank is rolled onto the conveying roller way to wait for conveying. Therefore, the problem that the original casting protection mechanism cannot pull the casting blank is solved, the casting blank orderly and controllably rolls onto a conveying roller way to wait for conveying, stable feeding of a skin milling machine is achieved, and the milling efficiency is guaranteed. Meanwhile, the casting blank stirring machine prevents a plurality of blanks from rolling to the position below a belt of the stirring machine through a second blocking rod. In addition, when the material poking machine fails, the continuous rolled cast blank can be limited through the casting block assembly, so that the cast blank orderly rolls to the conveying roller way, the feeding of the skin milling machine is ensured, and the influence caused by equipment failure is reduced.

In addition, the embodiment of the invention also provides a cast blank pulling system, which comprises the above cast blank pulling mechanisms arranged along the cast roller conveying tables in sequence; belts of the plurality of cast blank pulling mechanisms are respectively in contact with each section of the cast blank on the material storage table so as to adjust the placing and rolling direction of the cast blank. Specifically, in an embodiment, three casting blank shifting mechanisms may be sequentially arranged along a casting blank conveying roller way, belts of the three casting blank shifting mechanisms act on the head end and the tail end of the casting blank and the middle portion of the casting blank respectively, and a force may be simultaneously applied to the casting blank to drive the casting blank to roll towards the conveying roller way, so that a phenomenon that the casting blank rolls from head end to tail asynchronously is avoided, the straightness of the casting blank is ensured, and the charging efficiency of the casting blank is ensured.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
