[0024] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0026] like Figures 1-6 The traction and shaping device for producing copper alloy wire shown includes a base 1, a winding rod 101 on one side of the base 1, an unwinding rod 102 on the other side of the base 1, a mounting plate 103 fixedly connected to the top of the base 1, a liquid storage chamber 104 opened on the top of the base 1, a pump body 105 inside the liquid storage chamber 104, a filter screen plate 2 fixedly connected to the inner wall of the liquid storage chamber 104, two symmetrically distributed rollers 3 rotatably connected to the surface of the mounting plate 103, and a processing module 4 located between the two rollers 3 on the surface of the mounting plate 103.

[0027] The processing module 4 includes a processing component and an auxiliary component 41. The processing component is disposed on the surface of the mounting plate 103 and is used for wire drawing of copper material. The auxiliary component 41 is disposed on the surface of the processing component.

[0028] The winding rod 101 can be driven by a motor to rotate and achieve the winding operation. This method is a relatively mature technology in existing applications and will not be elaborated on here.

[0029] like Figures 1-6 As shown, the processing assembly includes an upper mounting block 403 and a lower mounting block 404. The lower mounting block 404 is fixedly connected to the surface of the mounting plate 103. The upper mounting block 403 is located above the lower mounting block 404, and a slide plate 402 is fixedly connected to one side of the upper mounting block 403. An electric push rod 401 is provided on one side of the mounting plate 103, and the output shaft of the electric push rod 401 is fixedly connected to the surface of the slide plate 402.

[0030] Both the upper mounting block 403 and the lower mounting block 404 have wire grooves 411 on opposite sides. The inner wall of the upper wire groove 411 is fixedly connected to the upper mold 407, and the inner wall of the lower wire groove 411 is fixedly connected to the lower mold 414 corresponding to the upper mold 407. The upper mold 407 and the lower mold 414 are joined together to form a wire drawing mold. Along the direction of copper alloy wire travel, the diameter of the wire drawing mold gradually decreases, that is, the diameter of the wire drawing mold decreases as the distance from the mounting plate 103 increases.

[0031] By designing the upper die 407 and the lower die 414 as separate units, the traditional wire drawing equipment can avoid the need to pass the wire through the drawing holes of the drawing die in sequence, reducing the difficulty of drilling. The copper wire to be processed is simply placed on the inner side of the lower die 414 in sequence and turned by the roller 3 before being placed and passed through the other lower die 414. It should be noted that the order of passing through the lower die 414 should be gradually away from the mounting plate 103, so as to gradually reduce the diameter of the copper wire during the processing. After placement, the upper mounting block 403 is moved down by starting the electric push rod 401 to connect the upper die 407 and the lower die 414, thereby forming a wire drawing die that works with the winding rod 101 to achieve the traction and shaping of the copper alloy wire.

[0032] like Figures 1-6 As shown, the upper mounting block 403 has a first connecting cavity 405 inside, and an insertion tube 408 is fixedly connected to the bottom of the upper mounting block 403. The upper mounting block 403 has an inlet channel 406 that communicates with the insertion tube 408 inside.

[0033] The lower mounting block 404 has a second connecting cavity 410 inside. The water outlet of the pump body 105 is connected to a connecting pipe 415. The other end of the connecting pipe 415 is connected to the second connecting cavity 410. The top of the lower mounting block 404 has a mounting groove 409 corresponding to the insertion pipe 408. The inner bottom wall of the mounting groove 409 has an outlet channel 413 connected to the second connecting cavity 410.

[0034] Both the upper mounting block 403 and the lower mounting block 404 have evenly distributed diversion grooves 417 inside. Both the first connecting cavity 405 and the second connecting cavity 410 have drainage channels 418 that communicate with the adjacent diversion grooves 417 inside. The inner wall of the diversion groove 417 has drainage holes that communicate with the adjacent wire grooves 411. The inner wall of the drainage hole on the lower mounting block 404 is fixedly connected to a filter block 416.

[0035] The second connecting cavity 410 is provided with evenly distributed drain pipes 412. The upper end of the drain pipe 412 passes through the second connecting cavity 410 and is connected to the adjacent wire groove 411. The lower end of the drain pipe 412 passes through the lower mounting block 404.

[0036] Specifically, the liquid storage chamber 104 is filled with drawing oil, which is pumped to the inside of the connecting pipe 415 by the pump body 105, and then introduced into the second connecting chamber 410. After the upper mounting block 403 and the lower mounting block 404 are connected, the insertion tube 408 can be inserted into the inside of the mounting groove 409, so that the drawing oil in the second connecting chamber 410 can be injected into the inlet channel 406 through the outlet channel 413 and the insertion tube 408, and then introduced into the first connecting chamber 405.

[0037] The drawing oil entering the first connecting cavity 405 and the second connecting cavity 410 can be discharged through the drain channel 418 and the drain hole to spray the surface of the copper wire. It can be used as a coolant during the processing and increase lubrication to avoid burrs. At the same time, it can clean the micro-debris generated during the drawing process of the copper wire. Finally, it drips into the storage cavity 104 through the openings at both ends of the wire groove 411 or the drain pipe 412 for reuse. The filter plate 2 can filter debris to avoid affecting subsequent use.

[0038] like Figures 1-6 As shown, the auxiliary component 41 includes two sets of fixing plates 4101 that are respectively fixedly connected to the surfaces of the upper mounting block 403 and the lower mounting block 404. A connecting plate 4104 is provided on the side of the fixing plate 4101 near the wire groove 411. An adjusting rod 4102 is fixedly connected to the side of the connecting plate 4104 near the fixing plate 4101. The other end of the adjusting rod 4102 passes through the adjacent fixing plate 4101. A spring 4103 is fixedly connected between the fixing plate 4101 and the connecting plate 4104. A cleaning sponge 4105 is fixedly connected to the other side of the connecting plate 4104.

[0039] Under the action of spring 4103, the two cleaning sponges 4105 can be pressed tightly against the surface of the copper wire, cleaning the lubricating oil on the surface of the copper wire during the movement of the copper wire, avoiding excessive lubricating oil on the pulley 3 and causing slippage, and will not affect the placement of the copper wire. Compared with the traditional structure, it can effectively improve the wire threading efficiency.

[0040] Working principle: By designing the upper die 407 and lower die 414 as separate units, the traditional wire drawing equipment avoids the need to sequentially pass the wire through the drawing holes of the drawing die, reducing the difficulty of drilling. The copper wire to be processed is simply placed on the inner side of the lower die 414, and then rotated by the roller 3 before being placed through the other lower die 414. It is important to note that the order of passing through the lower dies 414 should gradually move away from the mounting plate 103, thus achieving the goal of gradually reducing the diameter of the copper wire during processing. After placement, the electric push rod 401 is activated to move the upper mounting block 403 downwards, achieving docking between the upper die 407 and the lower die 414, thereby forming a wire drawing die assembly. The winding of the coil 101 achieves the traction and shaping of the copper alloy wire. During the processing, the drawing oil is delivered to the second connecting cavity 410 and the first connecting cavity 405 through the pump body 105. The drawing oil entering the first connecting cavity 405 and the second connecting cavity 410 can be discharged through the drain channel 418 and the drain hole to spray the surface of the copper wire. It can be used as a coolant during the processing and increases lubrication to avoid burrs. At the same time, it can clean the micro-debris generated during the drawing process of the copper wire. Finally, it drips into the storage cavity 104 through the openings at both ends of the wire groove 411 or the drain pipe 412 for reuse. The filter plate 2 can filter debris to avoid affecting subsequent use.
