Description

Technical Field

[0001] This invention relates to the field of wire drawing equipment technology, specifically to a copper wire drawing device for manufacturing wires and cables. Background Technology

[0002] In the manufacturing process of wires and cables, copper wire drawing is one of the core processes. Its purpose is to draw thick-diameter copper rods into thin-diameter copper wires that meet production requirements. The diameter accuracy and surface smoothness of the copper wires directly determine the conductivity and service life of the wires and cables.

[0003] Before the wire drawing operation begins, the front end of the copper wire must be passed through the die hole of the drawing die so that the traction mechanism can drive continuous drawing. The traditional die-threading method relies on manual operation. The copper wire end is first manually ground, sharpened, or annealed and softened, and then the operator aligns it with the die hole and inserts it. This is not only inefficient and labor-intensive, but also prone to problems such as die jamming and die-threading failure due to irregular ends and many burrs. Summary of the Invention

[0014] Preferably, the clamp includes a main body, and two linear actuators are fixedly mounted on both sides of the main body, and a clamping plate is fixedly mounted on the driving end of the two linear actuators.

[0015] Working principle: During wire drawing, the linear actuator extends and pushes the clamp to move towards the adjacent mold until the electric push cylinder connected to the clamp moves and aligns with the insertion slot inside the mold. The electric push cylinder extends and inserts into the insertion slot, pushing the limit pin out of the limit slot, thereby connecting the clamp to the mold and removing the limit on the mold. Then, the above steps are repeated to connect the mold to the adjacent mold until all molds are connected to the clamp. The mold and clamp are then moved to the side near the support plate by the extension of the linear actuator. One end of the copper material is ground thin and passed through the guide hole and the mold in sequence, and placed on the clamp. The clamp holds the copper material. The linear actuator retracts and pulls the copper material and the mold to move synchronously. When the mold moves to the initial limit position, the electric push cylinder connected to it retracts to limit and fix the mold. Then, the clamp pulls the copper material and the remaining molds to continue moving, so that the copper material is drawn as it passes through the mold. By repeating the above steps, the molds are reset one by one, so that the copper material passes through the molds in sequence and is drawn into wire.

[0016] This invention provides a copper wire drawing device for manufacturing electric wires and cables. It has the following beneficial effects: 1. This invention eliminates the need for manual grinding and sharpening of copper material ends. Copper material is quickly threaded through the mold by opening and closing the template, saving the tedious operation of repeated manual threading, greatly improving the success rate of threading and the continuity of wire drawing operations. At the same time, the clamp automatically pulls the copper material to complete the wire drawing, reducing the intensity of manual labor and human error, and improving the overall production efficiency.

[0017] 2. This invention allows for flexible adjustment of the mold spacing, control of the stretching length and stress distribution of multi-stage copper wire drawing, avoids local stress concentration, and adopts a step-by-step mold closing method of first centering left and right and then pressing up and down, so that the plastic deformation of the copper material is more uniform, effectively preventing wire breakage and surface scratches, ensuring the roundness, diameter accuracy and surface smoothness of the copper wire cross-section, and improving the conductivity and service life of wires and cables.

[0018] 3. The present invention provides frustum-shaped channels on both sides of the mold hole to reduce wear at the mold hole opening. The support can drive the connecting frame to rotate 180°, so as to realize the alternating use of both sides of the mold hole and avoid uneven wear and corner collapse caused by long-term use on one side.

[0019] 4. This invention uses a self-rotating nozzle to simultaneously complete lubrication and debris washing, making the wire drawing process smoother and more stable, reducing the probability of wire breakage and die jamming, and can automatically wash away copper powder and burrs stuck at the die hole entry angle.

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1, please refer to the appendix. Figure 1 -Appendix Figure 4 This invention provides a copper wire drawing device for manufacturing wires and cables, including a slide rail 1. A support plate 6 is fixedly mounted at one end of the slide rail 1, and a guide hole is formed on the upper side wall of the support plate 6. The diameter of the guide hole is the same as the initial diameter of the copper material, serving a supporting and guiding effect. A plurality of molds 2 are slidably mounted on the surface of the slide rail 1, and a clamp 3 is slidably connected to the slide rail 1 on one side of each mold 2. A linear actuator 4 is fixedly mounted on the surface of the slide rail 1. The linear actuator can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder, and the driving end of the linear actuator 4 is fixedly connected to the clamp 3. The molds 2, the slide rail 1, and the clamp 3 are equipped with… The position adjustment component 5 includes a groove 501, several limiting grooves 505, and a connecting arm 506. The groove 501 is opened on the lower side wall of the mold 2. A slide plate 502 is slidably connected in the groove 501, and an elastic element 503 is fixedly connected between the slide plate 502 and the groove 501. A limiting post 504 is fixedly provided on the lower side wall of the slide plate 502. The limiting grooves 505 are opened on the inner side wall of the slide rail 1. The connecting arm 506 is fixedly provided on the side walls of the mold 2 and the fixture 3 respectively, and an electric push cylinder 507 is fixedly provided on the surface of the connecting arm 506. An insertion groove is opened on the surface of the slide plate 502.

[0025] Specifically, the limiting post 504 is tightly inserted into the corresponding limiting groove 505 by the elastic force of the elastic element 503, thereby fixing the position of the mold 2. During wire drawing, the linear actuator 4 extends and pushes the clamp 3 to move towards the adjacent mold 2 until the electric push cylinder 507 connected to the clamp 3 moves and aligns with the insertion groove inside the mold 2. At this point, the electric push cylinder 507 extends and inserts into the insertion groove, pushing the limiting post 504 out of the limiting groove 505, thereby connecting the clamp 3 to the mold 2 and removing the limiting force on the mold 2. The above steps are then repeated to connect mold 2 to adjacent molds 2 until all molds 2 are connected to clamp 3. Mold 2 and clamp 3 are then extended and moved to the side near support plate 6 via linear actuator 4. One end of the copper material is ground thin and passed through the guide hole and mold 2 sequentially, and placed on clamp 3. The copper material is then clamped by clamp 3. The linear actuator 4 retracts, pulling the copper material and mold 2 synchronously. When mold 2 moves to the initial limit position, the electric push cylinder 507 connected to it retracts, causing the mold... The device uses clamp 2 for limiting and fixing, and then clamp 3 pulls the copper material and the remaining molds 2 to continue moving, so that the copper material is drawn into wire as it passes through the mold 2. By repeating the above steps, the molds 2 are reset one by one, so that the copper material passes through the molds 2 in sequence and is drawn into wire. This device first reduces the spacing between the molds 2, then passes the thinner end of the copper material through the mold 2 and fixes it with clamp 3. It can then automatically pull the copper material through the molds 2 to draw into wire. The wire drawing force is uniform, which effectively reduces the probability of wire breakage and mold jamming, saves the tedious manual operation of repeatedly threading the molds, and greatly improves the efficiency of mold threading. With the continuity of wire drawing, and through the setting of multiple sets of limiting grooves 505, when the limiting post 504 in the mold 2 is inserted into the limiting groove 505 at different positions, the position of the mold 2 can be adjusted, thereby adjusting the spacing of the mold 2, controlling the stretching length and stress distribution of the copper material in the multi-stage wire drawing process, so that the copper material is subjected to more uniform stress and the transition is smoother when the diameter of the fixed die hole 26 is gradually reduced, effectively avoiding local stress concentration, wire breakage, scratching or diameter deviation caused by fixed spacing, and adapting to the feeding and drawing space requirements of copper materials of different lengths.

[0026] Please see the appendix Figure 2 The clamp 3 includes a main body 31, and linear actuators 32 are fixed on both sides of the main body 31. A clamping plate 33 is fixed on the driving end of the linear actuators 32. The surface of the clamping plate 33 can be provided with clamping grooves and anti-slip pads to improve the stability of clamping the copper material.

[0027] Specifically, the linear actuator 32 extends and retracts to open or close the clamping plate 33, thereby clamping the copper material.

[0028] Please see the appendix Figure 3 -Appendix Figure 4On both sides of the slide rail 1, corresponding to the limiting groove 505, there are strip-shaped slots 11 respectively. On the side opposite to the limiting post 504, the slide plate 502 is provided with a T-shaped snap connector 12. The snap connector 12 passes through the mold 2 and the slot 11. Several snap grooves 13 are provided laterally on the outer wall of the slot 11.

[0029] Specifically, when the limiting post 504 on one side of the sliding plate 502 in the mold 2 is inserted into the limiting groove 505, one end of the clamping connector 12 on the other side is simultaneously inserted into the inside of the clamping groove 13, thereby limiting the mold 2 from both sides and improving the stability of the mold 2 when drawing wire. When the sliding plate 502 is pushed by the electric push cylinder 507 and slides, causing the limiting post 504 to exit the limiting groove 505, one end of the clamping connector 12 simultaneously exits the clamping groove 13.

[0030] Example 2, please refer to the appendix. Figure 5 -Appendix Figure 6 To avoid manually thinning the copper wire ends before threading, this embodiment proposes the following solution: The mold 2 includes a base 21, a frame 22 is fixed above the base 21, and a support member 23 is provided at the center of the frame 22. A connecting frame 24 is provided at the top of the support member 23, and a template 25 is provided inside the connecting frame 24. The template 25 has mold holes 26 on its surface. The guide hole and the mold holes 26 are coaxially arranged. The diameter of the multiple mold holes 26 gradually decreases from the support plate 6 towards the clamp 3, allowing the copper material to pass through the progressively smaller diameter mold holes 26 in sequence. Frustum-shaped channels are provided on both sides of the mold holes 26, which can guide and guide the copper material, reduce the friction and collision between the copper wire ends and the edges of the mold holes 26, make it easier to thread the wire, and disperse stress and reduce entry resistance during drawing, preventing the copper wire surface from being damaged by the mold holes 26. Scratching and roughening improve the surface smoothness of the copper wire, while reducing wear at the opening of the die hole 26, extending the service life of the die 2, making the wire drawing process smoother and more stable, and reducing the probability of wire breakage. The template 25 is composed of side plates 1 251 on the left and right sides and side plates 252 on the top and bottom sides. When side plates 1 251 and side plates 252 are closed, they form the die hole 26. The top of the frame 22 and the bottom of the connecting frame 24 are respectively fixed with the driving end of the linear actuator 3 253, which is fixedly connected to the two side plates 252. Linear actuator 4 254 is fixed on both sides of the frame 22. The connecting frame 24 has through holes reserved on both sides for the linear actuator 4 254 to pass through. The connecting frame 24 has elastic and retractable pull rods 255 fixed on both sides, and the other end of the pull rods 255 is fixedly connected to the side plate 1 251.

[0031] Specifically, during copper piercing, linear actuators 3 (253) and 4 (254) retract respectively. Actuator 3 (253) moves the upper side plate 2 (252) upwards and the lower side plate 2 (252) downwards. The left side plate 1 (251) moves to the left via the pull rod 255, and the right side plate 1 (251) moves to the right, thus opening the template 25 and the die hole 26, allowing the copper end to pass through. After the mold 2 slides back to its original position, linear actuator 4 (254) extends and presses against the two side plates 1 (251) to slide back to its original position, squeezing the copper from both sides. Then, linear actuator 3 (253) extends, causing the two side plates 2 (252) to reset and squeeze the copper from both the top and bottom, compressing the area where the copper passes through the die hole 26 into a diameter and shape compatible with the die hole 26. This allows the copper to be drawn into wires later without needing to grind the copper, thus achieving copper piercing. When the clamp 3 slides to the traction mechanism… After removing the clamping and cutting off the undrawn end of the copper material, it is manually connected to the traction mechanism for pulling. The side plate adopts a step-by-step mold-closing method of first pressing left and right, then pressing up and down. This method can accurately center and position the copper material first, avoiding deviation and skewing during mold closing. Then, the diameter reduction and forming are gradually completed, making the plastic deformation of the copper material more uniform and the stress more gentle. This effectively prevents stress concentration, wire breakage and surface scratches. At the same time, it ensures that the mold hole 26 is closed and neat, and the roundness and diameter accuracy of the copper wire cross section are higher. It can also reduce mold wear and extend service life. No manual pre-treatment of the copper material end is required throughout the process, making the mold threading smoother and more efficient. Moreover, this mold threading method eliminates the tedious processes of manual grinding, sharpening and manual mold threading, reducing labor intensity and human error. It avoids mold jamming, scratches and wire breakage caused by burrs and irregularities at the copper material end, improves the success rate of mold threading and the continuity of wire drawing operations, and ensures the accuracy of copper wire diameter and surface smoothness, effectively improving the quality and production efficiency of wire and cable products.

[0032] Please see the appendix Figure 5 The support member 23 includes a linear actuator 231 fixedly connected to the frame 22, and a motor 232 is fixedly mounted on the drive end of the linear actuator 231. The drive end of the motor 232 is fixedly connected to the connecting frame 24.

[0033] Specifically, the height of the die hole 26 is adjusted by the linear actuator 231. When the template 25 is opened, the linear actuator 231 is first retracted to make the connecting frame 24 lower than the copper material. Then, the motor 232 drives the connecting frame 24 to rotate 180°, which adjusts the orientation of the die hole 26 so that both sides of the die hole 26 can be used for wire drawing. This avoids uneven wear and corner collapse caused by long-term use on one side, thereby improving the utilization rate of the mold 2 and extending the service life of the mold 2.

[0034] Please see the appendix Figure 4One end of the slide rail 1 is fixedly connected to a support plate 6. A self-rotating nozzle 7 is provided on one side of the guide hole and the mold hole 26, which are arranged in a ring and facing the frustum-shaped channel. The nozzle 7 is fixedly connected to the support plate 6 or the frame 22 through a connecting rod. The self-rotating nozzle 7 includes a ring-shaped shell with a U-shaped cross-section. A sealing ring is rotatably provided on the inner side of the shell. A blade distributed in a ring is fixed on the outer side wall of the sealing ring. The nozzle 7 is connected and fixed on the inner side wall of the sealing ring. A liquid inlet is provided on the outer side wall of the shell. When the lubricating oil flows in the shell, it drives the sealing ring and the nozzle 7 to rotate and spray the lubricating oil through cooperation with the blade.

[0035] Specifically, the nozzle 7 is connected to a lubricating oil pump. The lubricating oil pump inputs lubricating oil into the nozzle 7, which drives the nozzle 7 to rotate and spray lubricating oil onto the copper surface, reducing the resistance during wire drawing, achieving a lubricating effect, and washing away the debris generated during wire drawing in the frustum-shaped channel.

[0036] Example 3, please refer to the appendix. Figure 7 -Appendix Figure 10During the wire drawing process, copper powder and burrs accumulate at the corner of the die hole 26 and become taut. Although the nozzle 7 can wash away some of the copper powder or burrs, the effect is poor and it is difficult to effectively remove the copper powder and burrs stuck at the corner of the die hole 26. The copper wire will still break after a long period of wire drawing. This example proposes the following solution to solve the above problems: the side plate 251 includes an intermediate layer 2511, and the outer wall of the intermediate layer 2511 is fixed with a spring. The first elastic telescopic rod 2516 has an elastic force greater than the pulling force of the pull rod 255. Sliding layers 2512 are slidably disposed on both sides of the first intermediate layer 2511, and an elastic element 2513 is fixed between the first intermediate layer 2511 and the sliding layer 2512. The elastic element 2513 applies a pushing force to the sliding layer 2512, causing it to slide away from the copper material. The second side plate 252 includes the second intermediate layer 2521, and the second intermediate layer 2521... The outer wall is fixed with an elastic telescopic rod 2526. Sliding layers 2522 are slidably disposed on both sides of the intermediate layer 2521. An elastic element 2523 is fixed between the intermediate layer 2521 and the sliding layer 2522. The elastic element 2523 is used to apply a pushing force to the sliding layer 2522, causing it to slide away from the copper material. The elastic telescopic rod consists of a slidingly connected outer cylinder and an inner rod, and an elastic element disposed within the outer cylinder that applies an elastic force to the inner rod to extend it. The components consist of T-shaped guide grooves 2517 on the upper and lower sides of the first intermediate layer 2511, T-shaped guide blocks 2527 fixed on both sides of the second intermediate layer 2521, the inner rod of the first elastic telescopic rod 2516 connected to the first intermediate layer 2511, and the outer cylinder connected to the extrusion arm 2514, the inner rod of the second elastic telescopic rod 2526 connected to the second intermediate layer 2521, and the outer cylinder connected to the third linear actuator 253 and the push column 2524.

[0037] Specifically, when the die hole 26 needs to be closed, the linear actuator 3 253 first extends to move the intermediate layer 2521 onto the movement trajectory of the intermediate layer 1 2511. Then, the linear actuator 4 254 pushes the intermediate layer 1 2511 against the elastic telescopic rod 1 2516 until it reaches the intermediate layer 2521 (at this time, the elastic telescopic rod 1 2516 is compressed to its minimum amplitude). Then, the linear actuator 3 253 extends again to move the intermediate layer 2521 and drive the guide block 2527 to insert into the guide groove 2517, limiting the position of the intermediate layer 1 2511. Then, the linear actuator 4 254 retracts to cancel the push on the intermediate layer 1 2511. Finally, the intermediate layer 2521 continues to extend until the intermediate layer 1 2511 and the intermediate layer 2521 close to form the die hole 26 (at this time, the guide block 2527 slides to the inner edge of the guide groove 2517 and the elastic telescopic rod 2526 is compressed to its minimum amplitude).

[0038] Please see the appendix Figure 7 -Appendix Figure 10 An L-shaped compression arm 2514 is fixed to the outer wall of the first elastic telescopic rod 2516. Limiting protrusions 2515 are fixed to the upper and lower sides of the first sliding layer 2512 respectively. A pushing column 2524 is fixed to the outer side of the second elastic telescopic rod 2526. A fixing ear is fixed to the outer side of the second intermediate layer 2521. A rotating frame 2525 is rotatably provided on the upper side wall of the fixing ear.

[0039] Specifically, when only intermediate layer one 2511 and intermediate layer two 2521 are closed, the copper material is stopped from being pulled. Since sliding layer two 2522 and sliding layer one 2512 remain in a sliding, extended state, the frustum-shaped channel is opened, allowing the nozzle 7 to thoroughly rinse the debris accumulated in the frustum-shaped channel. After rinsing, the linear actuator four 254 extends and pushes sliding layer one 2512 towards one side of the copper material through the squeezing arm 2514. Simultaneously, it moves the limiting protrusion 2515 to the rear of intermediate layer two 2521 for limiting, thus locking intermediate layer two 2521 to prevent it from retracting. Then the linear actuator four 254... The retraction of the third actuator 253 causes the second elastic telescopic rod 2526 to extend. The second elastic telescopic rod 2526 drives the push column 2524 to rotate one end of the rotating frame 2525. The other end of the rotating frame 2525 applies a pushing force to the second sliding layer 2522, causing the second sliding layer 2522 to move towards the copper material. This causes the first sliding layer 2512 and the second sliding layer 2522 to close and form a frustum-shaped channel. The openable frustum-shaped channel allows for the removal of copper powder or burrs and other debris stuck inside. During this process, the die hole 26 remains closed to prevent the copper wire from shifting or moving when removing debris.

[0040] Workflow: During copper piercing, linear actuators 3 (253) and 4 (254) retract respectively. Linear actuator 3 (253) drives the upper side plate 2 (252) to move upward and the lower side plate 2 (252) to move downward. The left side plate 1 (251) moves to the left by the pull rod 255, and the right side plate 1 (251) moves to the right, thereby opening the template 25 and the die hole 26 so that the copper end can pass through the die hole 26. After the mold 2 slides back to its original position, the linear actuator 4 (254) in the mold 2 extends and pushes against the two side plates 1 (251) to slide back to its original position and squeezes the copper from the left and right sides. Then, the linear actuator 3 (253) extends to reset the two side plates 2 (252) and squeezes the copper from the top and bottom sides, squeezing the area where the copper passes through the die hole 26 into a diameter and shape that matches the die hole 26. This allows the copper material to be drawn into wires after passing through the die hole 26, thus eliminating the need to grind the copper material and achieving copper piercing.

[0041] The copper material is then held by clamp 3. The linear actuator 4 retracts and pulls the copper material and the mold 2 to move synchronously. When the mold 2 moves to the initial limit position, the electric push cylinder 507 connected to it retracts to limit and fix the mold 2. Then the clamp 3 pulls the copper material and the rest of the mold 2 to continue to move, so that the copper material is drawn as it passes through the mold 2. By repeating the above steps, the molds 2 are reset one by one, so that the copper material passes through the molds 2 in sequence and is drawn into wire.

[0042] Those skilled in the art can connect all electrical components and their compatible power supplies in this case via wires.
