Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of drawing machines, and in particular, to a drawing machine for zinc wire production. Background Art

[0002] As a metal processing equipment, the drawing machine is mainly composed of a wire-paying device, a drawing machine, a die device, a traction device, and a wire-taking device. The wire-paying device is responsible for releasing the metal raw materials to be processed, such as zinc wire coils, to ensure that the raw materials can enter the drawing process. The drawing machine is the core power source, usually equipped with a high-power motor and transmission system that can generate stable pulling force. The die device determines the shape and size of the drawn product. When the metal material passes through the die, it is forced to be shaped into the target shape. The traction device is used to pull the metal material during the drawing process to ensure the continuity of the drawing operation. The wire-taking device will neatly wind and collect the finished wire rods that have been drawn for subsequent processing.

[0003] The zinc wire drawing process carries the risk of wire breakage due to the material properties of the wire and the complex stress changes during the drawing process. Existing automated, continuously operating drawing machines do not stop immediately after a wire breakage occurs. The broken wire, under the force of the continued operation of the equipment, can fly out at high speeds, posing a serious threat to the operator's safety and compromising production efficiency and safety. This not only creates the risk of injury but also limits improvements in production efficiency and the maintenance of a safe production environment. Summary of the Invention

[0004] To overcome the above-mentioned defects, the embodiments of the present disclosure provide a drawing machine for zinc wire production, which solves the technical problem in the prior art that during the zinc wire drawing process, broken zinc wire flies out at high speed under the force of continuous operation of the equipment.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a drawing machine for zinc wire production, comprising:

[0006] frame;

[0007] A diameter reducing die is provided on the frame, and the diameter reducing die is used for forming the zinc wire;

[0008] A first clamping member is located at the feed end of the diameter reduction die, and the first clamping member includes:

[0009] A first rotating roller is arranged on the frame;

[0010] a second roller, disposed on the frame, forming a first feeding gap between the first roller and the second roller, the first feeding gap being used to feed the zinc wire to the diameter reduction die, the first roller and the second roller both being in contact with the zinc wire, and driving the first roller and the second roller to rotate when the zinc wire moves, and stopping rotating when the zinc wire breaks;

[0011] A conveying member is arranged on the frame, and is used to convey the zinc wire to pass through the first feeding gap and the reducing die in sequence.

[0012] For example, in a zinc wire production drawing machine provided in at least one embodiment of the present disclosure, the first clamping member further includes:

[0013] a first swing arm, one end of which is hingedly mounted on the frame;

[0014] a first mounting block hingedly mounted on the other end of the first swing arm, the first roller being rotatably mounted on the first mounting block;

[0015] The second mounting block is slidingly arranged on the first mounting block, and the second roller is rotatably arranged on the second mounting block. The second mounting block is configured to be close to the first mounting block so that the first roller and the second roller can approach each other to clamp the broken zinc wire. The second mounting block is configured to be away from the first mounting block and to drive the first roller and the second roller to move away from each other so that the first roller and the second roller rotate under the drive of the zinc wire. After the first rocker arm is configured to swing downward so that the first feeding gap is away from the feed end, the second mounting block can slide close to the first mounting block so that the first roller and the second roller can approach each other to clamp the broken zinc wire. After the first rocker arm is configured to swing upward, the first feeding gap can be located at the feed end of the reducing die.

[0016] For example, in a zinc wire production drawing machine provided in at least one embodiment of the present disclosure, the first clamping member further includes:

[0017] a first elastic member, one end of which is disposed on the first mounting block, and the other end of which is disposed on the second mounting block; when the first elastic member is extended, the first roller and the second roller move away from each other, so that the zinc wire can drive the first roller and the second roller to rotate after moving in the first feeding gap; and when the first elastic member is contracted, the first roller and the second roller move closer to each other to clamp the broken zinc wire;

[0018] A limit rod is arranged on the frame, and has a limit protrusion on the limit rod. The first rocker arm is configured to swing downward and drive the second mounting block away from the limit protrusion so that the first mounting block and the second mounting block are away from each other. The first rocker arm is configured to swing upward and drive the second mounting block to abut against the limit protrusion so that the first mounting block and the second mounting block are close to each other.

[0019] For example, in a zinc wire production drawing machine provided in at least one embodiment of the present disclosure, the first swing arm has a first limiting hole, the frame has a second limiting hole, and the zinc wire production drawing machine further includes:

[0020] A first limiting post is slidably arranged in the second limiting hole. The first limiting post is configured to slide out of the second limiting hole and then slide into the first limiting hole, so that the other end of the first rocker arm is located at the feed end of the reducing mold. The first limiting post is configured to slide into the second limiting hole, and then the first rocker arm can swing relative to the frame.

[0021] For example, in a zinc wire production drawing machine provided in at least one embodiment of the present disclosure, the zinc wire production drawing machine further includes a second clamping member, which is disposed on the discharge end of the diameter reduction die, and the second clamping member includes:

[0022] a second swing arm, one end of which is hingedly mounted on the frame;

[0023] a third mounting block, disposed on the other end of the second rocker;

[0024] a third rotating roller, rotatably mounted on the third mounting block;

[0025] The fourth roller is rotatably arranged on the third mounting block, and a second feeding gap is formed between the third roller and the fourth roller, and the second feeding gap is used for passing the zinc wire.

[0026] For example, in a zinc wire production drawing machine provided by at least one embodiment of the present disclosure, the second swing arm has a third limiting hole, the frame also has a fourth limiting hole, and further includes:

[0027] The second limiting column is slidably arranged in the fourth limiting hole. The second limiting column is configured to slide out of the fourth limiting hole and then slide into the third limiting hole, so that the other end of the second rocker arm is close to the discharge end of the reducing mold. The second limiting column is configured to slide into the fourth limiting hole, and then the second rocker arm can swing relative to the frame.

[0028] For example, at least one embodiment of the present disclosure provides a zinc wire production drawing machine, further comprising:

[0029] A rotating rod, one end of which is arranged on the first limiting column;

[0030] A rotating sleeve, one end of which is disposed on the second limiting column, a clamping protrusion is provided on the inner cavity wall of the other end of the rotating sleeve, and an annular groove is provided on the outer peripheral wall of the other end of the rotating rod. The annular groove has an opening, and the clamping protrusion is inserted into the annular groove through the opening, so that the rotating sleeve can be sleeved on the rotating rod;

[0031] There are several second elastic members, one end of which is set on the first limiting column and / or the second limiting column, and the other end is set on the frame. The second elastic member is used to provide a force for the first limiting column to slide out of the first limiting hole or to provide a force for the second limiting column to slide out of the third limiting hole.

[0032] For example, in a zinc wire production drawing machine provided in at least one embodiment of the present disclosure, the reducing die includes:

[0033] A mold base, arranged on the frame;

[0034] A mold core is detachably arranged on the mold base, and the mold core has a mold hole. The zinc wire passes through the first feed gap, the mold hole and the second feed gap in sequence.

[0035] For example, in a drawing machine for zinc wire production provided in at least one embodiment of the present disclosure, the conveying member includes a plurality of wire winding rollers, which are rotatably arranged on the frame, and the wire winding rollers are used to wind the zinc wire. The wire winding rollers are configured to provide power for the zinc wire to pass through the first feed gap, the die hole and the second feed gap in sequence after rotation.

[0036] For example, in a drawing machine for zinc wire production provided in at least one embodiment of the present disclosure, the wire winding roller has an annular limiting groove, and the zinc wire is wound in the annular limiting groove.

[0037] The beneficial effects of the embodiments of the present disclosure are:

[0038] In the present disclosure, a reducing die is mounted on a machine frame using bolts or other fastening methods. The die has a channel of specific shape and size inside to reduce the diameter of the zinc wire. A first clamping member is located at the feed end of the reducing die. The first and second rollers of the first clamping member can be made of smooth, wear-resistant metal. The second roller slides relative to the first roller via a sliding mechanism (such as a screw-nut mechanism or a cylinder). The first and second rollers are positioned opposite each other, forming a first feeding gap for the zinc wire to pass through. If the zinc wire breaks, it cannot continue to pass through the reducing die, causing it to stop moving within the first feeding gap. The second and first rollers stop rotating, and the first and second rollers signal an alarm to prevent the equipment from idling. The diameter of the first feeding gap is larger than the diameter of the reducing die channel. This first feeding gap allows the zinc wire to be pre-reduced, reducing the possibility of breakage.

DETAILED DESCRIPTION

[0050] The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than to limit the present disclosure.

[0051] To simplify the drawings, only the parts relevant to the disclosure are schematically shown in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0052] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on the specific circumstances.

[0053] In the present disclosure, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature includes the first feature being directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0054] In the description of this embodiment, the terms "up", "down", "left", "right", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation of the present disclosure.

[0055] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0056] like Figures 1 to 3 、 Figure 9 The figure shows a zinc wire drawing machine for production in one embodiment of the present disclosure. A reducing die 2 is mounted on a machine frame 1 via bolts or other fastening methods. The die 2 has a channel of specific shape and size inside to reduce the diameter of the zinc wire. A first clamping member 3 is located at the feed end of the reducing die 2. The first and second rollers 31, 32 of the first clamping member 3 can be made of a smooth, wear-resistant metal material. The second roller 32 slides relative to the first roller 31 via a sliding mechanism (such as a screw-nut mechanism, a cylinder, etc.). The first and second rollers 31, 32 are positioned opposite each other, forming a first feed gap 321 for the zinc wire to pass through. If the zinc wire breaks, it cannot continue to pass through the reducing die 2, causing it to stop moving within the first feed gap 321. The second and first rollers 32, 31, will not continue to rotate. The first and second rollers 31, 32, can signal an alarm, triggering an alarm to prevent the equipment from idling. Moreover, the diameter of the first feeding gap 321 is larger than the diameter of the channel of the diameter-reducing die 2 . The first feeding gap 321 can pre-reducing the diameter of the zinc wire, thereby reducing the possibility of zinc wire breakage.

[0057] When the second roller 32 approaches the first roller 31, the first and second rollers 31 and 32 come into contact and become unable to rotate. Flat surfaces can be designed on the first and second rollers 31 and 32 to prevent them from rotating after contact. The first and second rollers 31 and 32 clamp the zinc wire, preventing it from flying due to equipment operation. If a zinc wire breaks during production, the second roller 32 is controlled to approach the first roller 31, clamping the broken zinc wire within the first feed gap 321. The first clamp 3 quickly clamps the zinc wire when it breaks, preventing it from flying and injuring the operator, effectively ensuring worker safety.

[0058] By providing the first clamping member 3, the zinc wire can be clamped in time when it breaks, preventing the zinc wire from becoming loose or falling during the drawing process, which is beneficial to the subsequent processing of the broken zinc wire and improves the continuity of production.

[0059] like Figure 2 、 Figure 3 As shown, the first mounting block 33 is made of metal and is connected to the rotation axis of the first roller 31 via bolts, enabling the first roller 31 to be rotatably mounted on the first mounting block 33. The second mounting block 34 is arbitrarily mounted on the first mounting block 33 via a guide rail and slider mechanism or a dovetail groove mechanism. The rotation axis of the second roller 32 is similarly connected to the second mounting block 34 via bolts. The first swing arm 35 is a metal rod, with its ends connected to the frame 1 and the first mounting block 33 via hinges. When the broken zinc wire needs to be pulled, the first and second mounting blocks 33 and 34 are driven together manually or mechanically (such as a cylinder), causing the first and second rollers 31 and 32 to clamp the broken zinc wire. This then drives the first swing arm 35 to swing downward, driving the first mounting block 33 downward. This, in turn, drives the broken zinc wire held in the first feeding gap 321 downward via the second mounting block 34, allowing it to be wound around the winding roller 10 to prevent it from becoming entangled in the gaps between components. The first clamping member 3 can not only clamp the broken zinc wire, but also conveniently move the zinc wire during subsequent processing to prevent the zinc wire from flying out.

[0060] like Figure 4 、 Figure 9As shown, the limiting rod 36 is fixed to the frame 1, and the limiting protrusion 361 can be welded or integrally formed on the limiting rod 36. The arcuate groove 341 on the second mounting block 34 is formed by machining. The first elastic member 37 can be a spring, one end of which is fixed to the first mounting block 33 by hooking or welding, and the other end is also fixed to the second mounting block 34. When the first swing arm 35 swings downward, the limiting protrusion 361 disengages from the arcuate groove 341. At this time, the first elastic member 37 contracts, causing the first and second mounting blocks 33 and 34 to move closer together. In other words, the second roller 32 approaches the first roller 31 to clamp the zinc wire. When the first swing arm 35 swings upward, it drives the second mounting block 34 toward the limiting protrusion 361, causing it to re-engage in the arcuate groove 341, limiting the position of the second mounting block 34. This ensures that after the zinc wire is re-drawn, the zinc wire can drive the first and second rollers 31 and 32 to move within the first feeding gap 321.

[0061] The coordination of the limiting rod 36, the arcuate groove 341, and the first elastic member 37 enables the first clamping member 3 to move the broken end of the zinc wire into the liquid storage tank on the frame 1 while clamping the zinc wire. Furthermore, the first feed gap 321 can automatically adjust the clamping force according to actual needs during the zinc wire drawing process, preventing the zinc wire from loosening due to factors such as vibration, thereby improving product quality during the drawing process. During normal zinc wire drawing, the first and second rollers 31, 32 rotate driven by the zinc wire. If the zinc wire breaks, the first elastic member 37 forces the first and second rollers 31, 32 to move closer together, preventing them from rotating relative to each other and allowing the zinc wire to be clamped.

[0062] like Figure 5 As shown, the first limiting hole 351 on the first rocker arm 35 and the second limiting hole 101 on the frame 1 are both formed by mechanical drilling. The first limiting column 4 is made of cylindrical metal material, and its diameter is compatible with the second limiting hole 101 and the first limiting hole 351. A driving device (such as a cylinder or an electric push rod) can be set on the frame 1 to push the first limiting column 4 to slide in the second limiting hole 101. When the first rocker arm 35 needs to be fixed, the driving device pushes the first limiting column 4 to slide out of the second limiting hole 101 and slide into the first limiting hole 351; when the first rocker arm 35 needs to be able to swing, the driving device pulls the first limiting column 4 back into the second limiting hole 101. The first clamping member 3 can move the clamped zinc wire downward, further reducing the safety risks that may be caused by the zinc wire breaking, making the production environment safer.

[0063] By setting the first limiting column 4, the relative motion state between the first swing arm 35 and the frame 1 can be controlled according to the needs of the production process. During the normal drawing process of the zinc wire, the first swing arm 35 is fixed to prevent its shaking from affecting the drawing effect; when the first swing arm 35 needs to swing, such as when processing broken zinc wire, the limit is released, which facilitates operation and improves the practicality and adaptability of the equipment. The first swing arm 35 in the present disclosure is a telescopic rod. When the first swing arm 35 swings downward, since the first mounting block 33 can only be raised and lowered along the frame 1, the first swing arm 35 contracts and descends. When the zinc wire breaks, the first swing arm 35 drives the zinc wire to swing downward, and the end part of the zinc wire can be led to the wire winding roller 10, which is convenient for subsequent re-leading. An emergency stop button or alarm button is designed under the swing arm. When the zinc wire breaks, the first swing arm 35 swings downward, triggering the button, causing the equipment to stop or alarm.

[0064] like Figure 6 As shown, the second swing arm 51 of the second clamping member 5 is a metal rod, one end hinged to the frame 1 and the other end bolted to the third mounting block 52. The third and fourth rollers 53, 54 are respectively mounted on the third mounting block 52 via bearings. The second feed gap 541 between the third and fourth rollers 53, 54 can be adjusted according to the diameter of the zinc wire. The installation positions of the first and second clamping members 3, 5 on the frame 1 are arranged according to the position of the reducing die 2 and the direction of zinc wire feeding, ensuring that the zinc wire can smoothly pass through the first feed gap 321, the reducing die 2, and the second feed gap 541 in sequence.

[0065] The second clamping member 5 cooperates with the first clamping member 3 to better clamp and guide the zinc wire, ensuring its straightness and stability during the drawing process. In particular, after the zinc wire passes through the reducing die 2, the second clamping member 5 can promptly clamp and guide the reduced zinc wire, preventing it from shifting or twisting due to uneven force, thereby improving product quality. This also helps to increase the automation level of the drawing process and reduce manual intervention. If the zinc wire breaks, the first clamping member 3 and the second clamping member 5 can pull the broken end of the zinc wire to prevent it from flying out and getting stuck in the gaps between components on the frame 1. The second clamping member 5 is located near the zinc wire take-up roller. Therefore, if the zinc wire breaks, there is no need to clamp the wire; instead, the broken end needs to be pulled into the liquid storage tank on the frame 1, which temporarily stores coolant. As the take-up roller rotates, the zinc wire is automatically reeled in. The present disclosure designs the third mounting block 52 as a structure that can be lifted and lowered along the frame 1, and the second swing arm 51 is also a telescopic rod. When the second swing arm 51 swings downward, the end of the broken zinc wire can be pulled onto the wire winding roller 10 to ensure normal zinc wire collection.

[0066] like Figure 6As shown, the third limiting hole 511 on the second rocker arm 51 and the fourth limiting hole 102 on the frame 1 are formed by mechanical drilling. The second limiting column 6 adopts a structure and material similar to that of the first limiting column 4, and its diameter is compatible with the fourth limiting hole 102 and the third limiting hole 511. A driving device (such as a cylinder or an electric push rod) is also provided on the frame 1 to control the sliding of the second limiting column 6 in the fourth limiting hole 102. When the second rocker arm 51 needs to be fixed, the driving device pushes the second limiting column 6 to slide out of the fourth limiting hole 102 and slide into the third limiting hole 511; when the second rocker arm 51 needs to be able to swing, the driving device pulls the second limiting column 6 back into the fourth limiting hole 102.

[0067] Similar to the limiting effect of the first limiting post 4 on the first swing arm 35, the second limiting post 6 can control the relative motion between the second swing arm 51 and the frame 1. At different production stages, the second swing arm 51 can be fixed or released according to actual needs, which is conducive to adapting to different production process requirements and handling emergencies.

[0068] like Figure 7As shown, the rotating rod 7 and rotating sleeve 8 ensure that the first and second rocker arms 35 and 51 rotate synchronously when the zinc wire breaks. Due to the action of the receiving roller, the third and fourth rollers 53 and 54 cannot immediately detect the breakage of the zinc wire. Therefore, the two rollers work together to achieve synchronized movement of the first and second rocker arms 35 and 51, facilitating subsequent operation. Both the rotating rod 7 and rotating sleeve 8 are made of metal. One end of the rotating rod 7 is secured to the first limiting post 4 by welding or threading, while one end of the rotating sleeve 8 is similarly secured to the second limiting post 6 by welding or threading. A latching protrusion 81 is machined into the inner wall of the other end of the rotating sleeve 8, while an annular groove 71 and an opening 711 are machined into the outer wall of the other end of the rotating rod 7. The second elastic member 9 is a spring, with multiple springs evenly distributed. The second elastic member 9 is secured to both the first and second limiting posts 4 and 6 by hooking or welding, and the other end of the second elastic member 9 is fixed to the frame 1. When the first limiting post 4 and the second limiting post 6 slide in the corresponding limiting holes. When the zinc wire is not broken, the first roller 31 and the second roller 32 rotate at the same speed. When the zinc wire is broken, due to the drive of the receiving roller and the wire winding roller 10, the speed of the zinc wire near the receiving roller remains unchanged, and the speed of the zinc wire near the feeding roller decreases, causing the first roller 31 and the second roller 32 to stop rotating, while the third roller 53 and the fourth roller 54 are still rotating. Speed ​​detectors are designed on the first mounting block 33 and the third mounting block 52. The two speed detectors transmit the speeds of the first roller 31 and the third roller 53 to the first driving member and the second driving member respectively. The first driving member drives the rotating rod 7 to rotate, and the second driving member drives the rotating sleeve 8 to rotate. The first driving member and the first roller 31 have the same speed. The second driving member converts the signal and drives the rotating sleeve 8 and the rotating rod 7 to rotate synchronously. When the first roller 31 stops rotating, the speed detector detects it and transmits the signal to the first driving member. The first driving member stops driving the rotating rod 7 to rotate, and the rotating sleeve 8 continues to rotate. When the rotating rod 7 and the rotating sleeve 8 rotate synchronously, due to the limitation of the annular groove 71 and the clamping protrusion 81, the rotating rod 7 and the rotating sleeve 8 are always in a connected state. When the rotating rod 7 and the rotating sleeve 8 rotate asynchronously, the clamping protrusion 81 slides into the sliding groove driven by the second elastic member 9. The sliding groove and the opening 711 are arranged along the length direction of the rotating rod 7. The sliding groove and the opening 711 are located on both sides of the annular groove. The rotating rod 7 and the rotating sleeve 8 slide with each other, and the first limiting column 4 and the second limiting column 6 disengage from the first limiting hole 351 and the third limiting hole 511 respectively. The first rocker arm 35 and the second rocker arm 51 swing downward, and the second elastic member 9 always provides force to slide the first limiting column 4 out of the first limiting hole 351 and the second limiting column 6 out of the third limiting hole 511.

[0069] like Figure 8As shown, the die base 21 is made of metal and is fixed to the frame 1 by bolts or welding. The die core 22 and die base 21 can be removably mounted using a threaded connection or a slotted connection, allowing for quick and easy replacement of the die core 22 with a different specification. The die hole 221 in the die core 22 is tailored to the desired final diameter of the zinc wire, ensuring that the zinc wire is reduced in diameter as it passes through the die hole 221.

[0070] The reducing die 2 adopts a structural design of a die base 21 and a detachable die core 22. When producing zinc wires of different specifications, it is only necessary to replace the corresponding die core 22 without replacing the entire reducing die 2, which greatly reduces production costs, improves the utilization efficiency of the equipment, and also facilitates the maintenance and care of the die.

[0071] like Figure 1 As shown, the winding roller 10 is mounted on the frame 1 via bearings and can be driven by a motor via a belt drive, chain drive, or gear drive. The motor's speed can be controlled by a speed control device such as a frequency converter to meet the requirements of different drawing speeds. As the winding roller 10 rotates, one end of the zinc wire is fixed to the winding roller 10. As the winding roller 10 rotates, the zinc wire is gradually wound around the winding roller 10, thereby providing power for the zinc wire to pass through the first feed gap 321, the die hole 221, and the second feed gap 541 in sequence.

[0072] Setting the wire roller 10 as the power source for zinc wire drawing can realize an automated drawing process and improve production efficiency. By controlling the rotation speed of the wire roller 10, the drawing speed of the zinc wire can be stably controlled, ensuring the uniformity and stability of the drawing process, which is beneficial to improving product quality. The annular limit groove 11 on the wire roller 10 is formed by mechanical processing, and the width and depth of the annular limit groove 11 are designed according to the diameter of the zinc wire and the winding requirements. When the zinc wire is wound on the wire roller 10, the zinc wire falls into the annular limit groove 11, and as the wire roller 10 rotates, the zinc wire is wound in an orderly manner in the annular limit groove 11. The setting of the annular limit groove 11 can effectively prevent the zinc wire from deviating or overlapping during the winding process, and ensure the neatness of the zinc wire winding. This is not only beneficial to improving the appearance quality of the product.

[0073] Working process:

[0074] During the normal drawing process, the zinc wire sequentially passes through the first feeding gap 321 of the first clamping member 3, the die hole 221 of the reduction die 2, and the second feeding gap 541 of the second clamping member 5, before being wound into the annular retaining groove 11 of the winding roller 10. Driven by a motor, the winding roller 10 rotates, providing power for the zinc wire drawing process, allowing the zinc wire to pass through the die hole 221 and undergo diameter reduction. During this process, the first clamping member 3 and the second clamping member 5 position the zinc wire and pre-reduce its diameter, ensuring stable drawing.

[0075] Broken zinc wire handling process: When the zinc wire breaks, a signal is sent via the speed detector to the first and second drive members, causing the first drive member to drive the rotating rod 7 and the second drive member to drive the rotating sleeve 8 at different speeds. Under the action of the second elastic member 9 and the chute, the first limiting post 4 slides into the second limiting hole 101, releasing the restraint on the first rocker 35. Since the first rocker 35 is initially tilted, it naturally swings downward. Simultaneously, the limiting protrusion 361 disengages the arcuate groove 341, and the first elastic member 37 pushes the second mounting block 34 and the second roller 32 downward, clamping the broken zinc wire. The downwardly swinging first rocker 35, through the first and second mounting blocks 33 and 34, drives the clamped zinc wire downward. Simultaneously, the second limiting post 6 slides into the fourth limiting hole 102, releasing the restraint on the second rocker 51. The third mounting block 52 then assists the second rocker 51 in handling the broken zinc wire. After the processing is completed, the first swing rod 35 and the second swing rod 51 are restored to the limit state to prepare for the next pulling operation.
