Description

Technical Field

[0001] This invention relates to the field of steel wire production equipment technology, specifically to a wire drawing device for stainless steel wire production. Background Technology

[0002] Stainless steel wire, as an important basic material in the industrial field, is widely used in machinery manufacturing, building structures, medical devices and other industries. In the wire production process, the wire drawing process is one of the core links. It uses multiple dies to gradually stretch the coarse steel wire to the target diameter, while optimizing the strength, surface finish and other properties of the steel wire. However, in high-speed wire drawing and winding operations, steel wire is prone to breakage due to factors such as internal material defects, die wear or tension fluctuations. If not handled in time, it will lead to problems such as continuous empty running of the take-up drum and messy tangling of broken wires. This not only wastes raw materials, but may also cause equipment failure, seriously affecting production efficiency and product quality.

[0003] Traditional wire drawing devices often rely on manual monitoring or simple mechanical sensors for wire breakage detection, which suffers from drawbacks such as delayed response and incomplete braking. For example, some devices require manual shutdown by operators after wire breakage, resulting in excessively long response times and disorderly accumulation of broken wires on the take-up drum, increasing the difficulty of subsequent processing. While devices using mechanical limit switches can achieve automatic shutdown, their braking mechanisms often employ single friction plates or electromagnetic brake designs, which lack sufficient braking torque and cannot quickly stop the take-up drum at high speeds. Furthermore, they lack wire breakage clamping capabilities, causing the broken wire to easily retract into the guide mechanism, significantly extending maintenance time. In addition, the reciprocating motion precision of existing wire feeding mechanisms is insufficient, easily leading to uneven distribution of the wire on the take-up drum, resulting in localized stress concentration and affecting subsequent processing performance. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide a wire drawing device for the production of stainless steel wire.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: a wire drawing device for stainless steel wire production, including a wire drawing frame, a wire drawing mechanism and a receiving platform on the wire drawing frame, a receiving cylinder rotatably mounted on the receiving platform for receiving the wire drawn out by the wire drawing mechanism, a receiving mechanism for driving the receiving cylinder to rotate on the receiving platform, a linkage mechanism for transmitting the power of the receiving mechanism to the receiving cylinder on the receiving platform, a braking mechanism for stopping the rotation of the receiving cylinder after the wire breaks on the receiving platform, a wire feeding mechanism for guiding the wire on the receiving platform, a sensing mechanism for sensing the integrity of the wire on the wire feeding mechanism, and a clamping mechanism for clamping the wire after it breaks on the wire feeding mechanism, wherein the sensing mechanism drives the linkage mechanism and the braking mechanism to start and stop synchronously.

[0006] As an improvement, the wire feeding mechanism includes a wire feeding frame set on the receiving platform, a reciprocating screw driven by a motor is rotatably mounted on the wire feeding frame, a wire feeding slide rod is mounted on the wire feeding slide rod, a wire feeding slider is slidably mounted on the wire feeding slide rod, a reciprocating slide plate that rotatably cooperates with the reciprocating screw is mounted on the lower end of the wire feeding slider, and a guide tube is mounted on the wire feeding slider.

[0007] As an improvement, the sensing mechanism includes a sensing carriage mounted on the wire feeding slider, a sensing slider slidably mounted on the sensing carriage, a sensing roller rotatably mounted on the sensing slider, a sensing spring connected to the wire feeding slider mounted on the sensing slider, a sensing rod slidably inserted onto the sensing slider, and a power mechanism on the sensing rod that enables synchronous start and stop of a drive linkage mechanism and a braking mechanism.

[0008] As an improvement, the receiving mechanism includes a receiving rack mounted on a receiving platform, on which a receiving disc driven by a motor is rotatably mounted. The linkage mechanism includes a linkage frame mounted on the receiving platform, on which a mounting plate connected to the receiving cylinder by bolts is rotatably mounted. A linkage slide column is provided on one side of the mounting plate, and a linkage disc that cooperates with the receiving disc is slidably sleeved on the linkage slide column. The linkage disc is provided with a linkage slip ring and a linkage spring. The linkage spring abuts against the mounting disc. The power mechanism drives the linkage disc to slide along the linkage slide column through the linkage slip ring.

[0009] As an improvement, the receiving rack is symmetrically provided with positioning rods, and a linkage fork that rotates and cooperates with the linkage slip ring is slidably provided on the positioning rods. The receiving rack is provided with a positioning frame, and a linkage plate is rotatably provided on the positioning frame. One end of the linkage plate is slidably cooperated with the linkage fork, and the other end of the linkage plate is slidably cooperated with the power mechanism.

[0010] As an improvement, the braking mechanism includes an upper brake plate and a lower brake plate rotatably mounted on the receiving platform. The upper brake plate and the lower brake plate are respectively provided with an upper brake pad and a lower brake pad that cooperate with the mounting plate. A brake connecting plate is rotatably mounted on the receiving platform. One end of the brake connecting plate is rotatably provided with a mating plate that is rotatably connected to the lower brake plate, and the other end of the brake connecting plate is rotatably provided with a synchronization plate that is rotatably connected to the upper brake plate. The brake connecting plate is driven to rotate by a power mechanism.

[0011] As an improvement, the receiving platform is provided with a brake slide groove, a brake slide bracket is slidably mounted on the brake slide groove, and a separation plate that is rotatably connected to the brake connecting plate is mounted on the brake slide bracket. The brake slide bracket is driven by a power mechanism to slide along the brake slide groove.

[0012] As an improvement, the power mechanism includes a longitudinal connecting rod and a transverse connecting rod rotatably mounted on the sensing slide rod. The transverse connecting rod is rotatably connected to the brake slide. The receiving platform is provided with a sensing slide groove. A drive slider rotatably connected to the longitudinal connecting rod is slidably mounted in the sensing slide groove. A drive crossbar that slidably engages with the linkage plate is mounted on the drive slider.

[0013] As an improvement, the wire feeding slider is provided with a fixed slide, and the clamping mechanism includes a clamping slider slidably disposed on the fixed slide. Two clamping sliders are provided, and each clamping slider is provided with a clamping tension spring connected to the other clamping slider on the same side. Both clamping sliders are provided with a unidirectional rotating roller.

[0014] The advantages of this invention compared to existing technologies are as follows: Multiple components, including the wire feeding mechanism, sensing mechanism, clamping mechanism, linkage mechanism, and braking mechanism, work closely together to construct a highly efficient and stable production system. The wire feeding mechanism precisely guides the steel wire, ensuring its stable position during the take-up process and reducing the risk of wire deviation or uneven winding. The sensing mechanism can quickly detect wire breakage. The braking mechanism and linkage mechanism respond synchronously, promptly stopping the take-up cylinder from rotating and preventing equipment failure or production accidents caused by wire breakage. This multi-mechanism collaboration greatly improves the stability and reliability of the production process. Specifically:

[0015] 1. After the steel wire breaks, the equipment can respond in a short time. The braking mechanism immediately stops the rotation of the receiving drum, avoiding excessive stretching or tangling of the steel wire caused by the receiving drum spinning idly, effectively reducing material waste. At the same time, the clamping mechanism fixes the broken steel wire in place, making it convenient for operators to quickly locate and handle the problem, shortening downtime caused by malfunctions and improving production efficiency.

[0016] 2. The reciprocating screw driven by the motor drives the wire feeding slider to reciprocate on the wire feeding slide bar, so that the steel wire in the guide tube can be evenly distributed on the take-up cylinder. This uniform winding method avoids stress concentration caused by uneven winding of steel wire, effectively improving the quality and stability of the steel wire after winding. In subsequent processing and use, it can reduce various failures caused by steel wire quality problems, and provide high-quality raw materials for downstream production.

[0017] 3. The design of the sensing roller and the rolling contact with the steel wire can sensitively detect subtle changes in the state of the steel wire. Once the steel wire breaks, the sensing slider moves quickly under the action of the sensing spring, and the power mechanism is quickly triggered through the sensing rod. The linkage mechanism and the braking mechanism respond synchronously. The whole process takes very little time, which greatly reduces the risk of equipment failure caused by steel wire breakage, ensures the safety of the production process, and reduces the possibility of equipment damage and accidents. At the same time, the overall structure of the sensing mechanism is relatively simple, consisting of basic components such as sensing carriage, sensing slider, sensing roller, sensing spring and sensing rod. The connection and cooperation between the components are clear and straightforward, which reduces the difficulty of manufacturing and installation, and also reduces the failure points caused by too many components and complex structure. This improves the reliability of the sensing mechanism and reduces maintenance costs and difficulties.

[0018] 4. The braking mechanism adopts the design of upper and lower brake plates clamping the mounting plate. The upper and lower brake pads act on the mounting plate at the same time, which greatly increases the friction during braking. It can quickly and effectively stop the rotation of the receiving cylinder. The braking effect is reliable, and the inertial rotation of the receiving cylinder during the braking process is significantly reduced, avoiding production accidents caused by untimely braking and ensuring production safety.

[0019] 5. The braking mechanism and the linkage mechanism are driven by the same power mechanism, which can achieve synchronous response when the steel wire breaks. The power mechanism controls the sliding of the brake slide to quickly drive the brake connecting plate to rotate, thereby making the upper and lower brake plates move quickly. The whole response process is smooth and fast. The fast response speed effectively shortens the time from the steel wire breaking to the stopping of the receiving cylinder, reduces material waste and equipment wear caused by the equipment running idle, and improves production efficiency.

[0020] 6. The design of the power mechanism enables extremely precise response to wire breakage. Even minute displacements of the sensing rod are accurately transmitted to the linkage and braking mechanisms via longitudinal and lateral connecting rods, ensuring the accuracy of power cutoff and braking. Throughout the response process, the actions of each component are seamlessly integrated, reducing energy loss and response delay, significantly improving braking efficiency in emergency situations, and effectively mitigating the risk of production accidents caused by wire breakage.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] Combined with appendix Figure 1 and attached Figure 2As shown, a wire drawing device for stainless steel wire production includes a wire drawing frame 1, a wire drawing mechanism 11 and a receiving platform 12 on the wire drawing frame 1, a receiving cylinder 13 rotatably mounted on the receiving platform 12 for collecting the wire drawn out by the wire drawing mechanism 11, a receiving mechanism 2 for driving the receiving cylinder 13 to rotate on the receiving platform 12, a linkage mechanism 3 for transmitting the power of the receiving mechanism 2 to the receiving cylinder 13 on the receiving platform 12, a braking mechanism 4 for stopping the rotation of the receiving cylinder 13 after the wire breaks on the receiving platform 12, a wire feeding mechanism 5 for guiding the wire on the receiving platform 12, a sensing mechanism 6 for sensing the integrity of the wire on the wire feeding mechanism 5, and a clamping mechanism 7 for clamping the wire after it breaks on the wire feeding mechanism 5. The sensing mechanism 6 drives the linkage mechanism 3 and the braking mechanism 4 to start and stop synchronously.

[0034] The working principle of this invention is as follows: First, wire drawing and collection are performed. When the equipment is started, the wire drawing mechanism 11 is installed on the wire drawing frame 1 to draw the stainless steel wire from the raw material form into the required specifications. This is the existing technology and will not be described in detail here. The drawn wire is guided by the wire feeding mechanism 5 and then wound onto the collection cylinder 13. The collection mechanism 2 is installed on the collection table 12 to provide power for the rotation of the collection cylinder 13. The power is effectively transmitted to the collection cylinder 13 by means of the linkage mechanism 3. The collection cylinder 13 rotates continuously to realize the winding and collection of the wire, thereby completing the wire drawing and collection work of stainless steel wire.

[0035] During the wire drawing and take-up process, the sensing mechanism 6 monitors the integrity of the wire in real time. Once the wire breaks, the sensing mechanism 6 quickly detects the abnormality and drives the braking mechanism 4 to stop the take-up cylinder 13 from rotating, thus preventing the wire from becoming tangled or the equipment from being damaged due to the continued operation of the take-up cylinder 13. At the same time, the sensing mechanism 6 drives the linkage mechanism 3 to stop, ensuring that the power of the take-up mechanism 2 will not continue to be transmitted to the take-up cylinder 13. During this period, the clamping mechanism 7 starts quickly after the wire breaks to clamp and fix the wire, preventing it from shifting due to equipment inertia or other factors, which facilitates subsequent maintenance and re-threading operations.

[0036] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 7 As shown, the wire feeding mechanism 5 includes a wire feeding frame 51 mounted on the receiving table 12. A reciprocating screw 52 driven by a motor is rotatably mounted on the wire feeding frame 51. A wire feeding slide rod 53 is mounted on the wire feeding frame 51. Two sets of wire feeding slide rods 53 are provided. A wire feeding slider 54 is slidably mounted on the wire feeding slide rod 53. A reciprocating slide plate 55 that rotatably cooperates with the reciprocating screw 52 is mounted on the lower end of the wire feeding slider 54. A guide tube 56 is mounted on the wire feeding slider 54. Both ends of the guide tube 56 are wide-mouth structures.

[0037] The working principle of the wire feeding mechanism 5: The power generated by the motor drives the reciprocating screw 52 of the wire feeding frame 51 on the take-up table 12 to rotate. Since the reciprocating slide plate 55 at the lower end of the wire feeding slider 54 cooperates with the reciprocating screw 52, ​​when the reciprocating screw 52 rotates, it drives the reciprocating slide plate 55 to move along the screw thread direction. Since the reciprocating slide plate 55 is fixed on the wire feeding slider 54, the wire feeding slider 54 will slide back and forth on the wire feeding slide bar 53. At the same time, the wire to be wound passes through the guide tube 56 on the wire feeding slider 54. The wide opening structure at both ends of the guide tube 56 facilitates the smooth entry and exit of the wire into and out of the guide tube 56, effectively reducing the probability of the wire getting stuck in the guide tube 56 during the process of entering and exiting. With the reciprocating motion of the wire feeding slider 54, the guide tube 56 also moves synchronously, so that the wire is evenly and orderly wound on the take-up cylinder 13, avoiding the phenomenon of uneven winding due to the wire being concentrated in a certain part of the take-up cylinder 13.

[0038] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 7 As shown, the sensing mechanism 6 includes a sensing carriage 61 mounted on the wire feeding slider 54, a sensing slider 62 slidably mounted on the sensing carriage 61, a sensing roller 63 rotatably mounted on the sensing slider 62, the sensing roller 63 being covered with polyurethane rubber, the sensing roller 63 rolling and abutting against the steel wire, a sensing spring 64 connected to the wire feeding slider 54 mounted on the sensing slider 62, a sensing rod 65 slidably inserted onto the sensing slider 62, and a power mechanism on the sensing rod 65 that drives the linkage mechanism 3 and brake the mechanism 4 to start and stop synchronously.

[0039] Working principle of sensing mechanism 6: During the production of stainless steel wire, sensing mechanism 6 works closely with wire feeding slider 54 to monitor the status of the wire in real time. When the wire is being fed normally, it moves under the guidance of guide tube 56 and rolls against sensing roller 63 on sensing slider 62. Since sensing slider 62 is connected to wire feeding slider 54 through sensing spring 64, the sensing spring 64 is in a certain contracted state, maintaining the relative position of sensing slider 62, so that sensing roller 63 can continuously and stably contact the wire. Once the wire breaks, the pressure of the wire on sensing roller 63 is instantaneous. As the sensing slider 62 disappears, it slides along the sensing slide frame 61 under the elastic force of the sensing spring 64. During the sliding of the sensing slider 62, the sensing slide rod 65 connected to the sensing slider 62 moves synchronously, triggering the power mechanism installed on the sensing slide rod 65. The power mechanism then takes effect and sends signals to the linkage mechanism 3 and the braking mechanism 4, causing them to start and stop synchronously. The linkage mechanism 3 stops transmitting power from the receiving mechanism 2 to the receiving cylinder 13, while the braking mechanism 4 causes the receiving cylinder 13 to stop rotating quickly, preventing chaos caused by the receiving cylinder 13 continuing to operate after the steel wire breaks.

[0040] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 As shown, the receiving mechanism 2 includes a receiving rack 21 mounted on the receiving platform 12, and a receiving disc 22 driven by a motor is rotatably mounted on the receiving rack 21. The linkage mechanism 3 includes a linkage frame 31 mounted on the receiving platform 12, and a mounting disc 32 connected to the receiving cylinder 13 by bolts is rotatably mounted on the linkage frame 31. A linkage slide column 33 is provided on one side of the mounting disc 32. A linkage disc 34 that cooperates with the receiving disc 22 is slidably sleeved on the linkage slide column 33. A sliding key that slidably cooperates with the linkage disc 34 is provided on the linkage slide column 33. The sliding key prevents the linkage disc 34 from rotating axially along the linkage slide column 33. A linkage slip ring 341 and a linkage spring 342 are provided on the linkage disc 34. The linkage spring 342 abuts against the mounting disc 32. The power mechanism drives the linkage disc 34 to slide along the linkage slide column 33 through the linkage slip ring 341.

[0041] The receiving rack 21 is symmetrically provided with positioning rods 24. The positioning rods 24 are slidably provided with a linkage fork 35 that rotates with the linkage slip ring 341. The linkage fork 35 has a U-shaped structure. The receiving rack 21 is provided with a positioning frame 23. The positioning frame 23 is rotatably provided with a linkage plate 36. One end of the linkage plate 36 is slidably engaged with the linkage fork 35, and the other end of the linkage plate 36 is slidably engaged with the power mechanism.

[0042] Working principle of the receiving mechanism 2: Under normal working conditions, the motor provides power to the receiving mechanism 2, driving the receiving disc 22 on the receiving rack 21 to rotate. The rotation of the receiving disc 22 is transmitted to the receiving cylinder 13 through the linkage mechanism 3 to realize the winding of the steel wire. Specifically, when the receiving disc 22 rotates, the linkage disc 34, which is matched with it, moves in a circular motion around the linkage slide column 33 in sync with the receiving disc 22 under the action of friction and with the restriction of the sliding key. Since the linkage disc 34 is connected to the mounting disc 32 through the linkage spring 342, under normal conditions, the elasticity of the linkage spring 342 makes the linkage disc 34 fit tightly against the receiving disc 22. The linkage disc 34 transmits power to the mounting disc 32 through the linkage slide column 33, thereby driving the receiving cylinder 13, which is fixed to the mounting disc 32 by bolts, to rotate, so as to realize the stable winding of the steel wire.

[0043] Once the sensing mechanism 6 detects a broken wire, the power mechanism activates, driving the linkage plate 36 to rotate. This rotation causes the linkage fork 35 to slide along the positioning rod 24. Simultaneously, the sliding fork 35, through the linkage slip ring 341, moves the linkage disc 34 away from the receiving disc 22 until it disengages, cutting off the power transmission between the receiving disc 22 and the receiving cylinder 13. At the same time, the braking mechanism 4 activates, stopping the receiving cylinder 13 from rotating and preventing chaos caused by its continued operation after the wire breakage.

[0044] Combined with appendix Figure 1 Appendix Figure 3 and attached Figure 6 As shown, the braking mechanism 4 includes an upper brake plate 41 and a lower brake plate 42 rotatably mounted on the receiving table 12. The upper brake plate 41 and the lower brake plate 42 are respectively provided with upper brake pads 411 and lower brake pads 421 that cooperate with the mounting plate 32. The upper brake pads 411 and lower brake pads 421 are made of copper-based powder metallurgy friction material with a temperature resistance of 350℃. The contact surface of the linkage plate 34 is coated with tungsten carbide. A brake connecting plate 43 is rotatably mounted on the receiving table 12, and one end of the brake connecting plate 43 is rotatably connected to the lower brake plate 42. The brake connecting plate 43 is connected to the brake connecting plate 43. The other end of the brake connecting plate 43 is rotatably connected to the upper brake plate 41. The brake connecting plate 43 is provided with a counterweight 45 on the side near the synchro plate 431. The brake connecting plate 43 is driven to rotate by a power mechanism. The receiving table 12 is provided with a brake slide groove 44. A brake slide 441 is slidably provided on the brake slide groove 44. A separation plate 442 is rotatably connected to the brake connecting plate 43 on the brake slide 441. The brake slide 441 is driven to slide along the brake slide groove 44 by a power mechanism.

[0045] Working principle of brake mechanism 4: When the wire drawing device for stainless steel wire production is running normally, brake mechanism 4 is in a non-braking state. The upper brake plate 41 and the lower brake plate 42 are both kept at a certain distance from the mounting plate 32. The take-up cylinder 13 rotates continuously and stably under the power transmitted by the linkage mechanism 3 to carry out wire winding operation.

[0046] When the sensing mechanism 6 detects a broken wire and triggers the power mechanism, the power mechanism controls the linkage mechanism 3 to cut off the power transmission between the receiving tray 22 and the receiving cylinder 13. Simultaneously, it drives the braking mechanism 4 to activate. The power mechanism pushes the brake slide 441 to slide along the brake groove 44. Since the separating plate 442 is rotatably connected to the brake slide 441 and the brake connecting plate 43, the sliding of the brake slide 441 causes the separating plate 442 to move, which in turn causes the brake connecting plate 43 to rotate around its rotation point on the receiving table 12. As the brake connecting plate... The rotation of plate 43 causes the mating plate 432, which is rotatably connected to one end of the brake connecting plate 43, to move the lower brake plate 42 upward. The synchronizing plate 431, which is rotatably connected to the other end of the brake connecting plate 43, causes the upper brake plate 41 to move downward. The upper brake plate 41 and the lower brake plate 42 move towards each other, so that the upper brake pad 411 and the lower brake pad 421 are tightly attached to the mounting plate 32. By increasing the friction, the mounting plate 32 and the connected receiving cylinder 13 are quickly stopped from rotating, effectively avoiding the chaos caused by the receiving cylinder 13 continuing to run after the steel wire breaks.

[0047] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4 Appendix Figure 6 and attached Figure 7As shown, the power mechanism includes a longitudinal connecting rod 651 and a transverse connecting rod 652 rotatably mounted on the sensing slide rod 65. The transverse connecting rod 652 is rotatably connected to the brake slide 441. The receiving platform 12 is provided with a sensing slide groove 66. A drive slider 661 rotatably connected to the longitudinal connecting rod 651 is slidably mounted in the sensing slide groove 66. A PTFE wear-resistant pad is embedded at the bottom of the drive slider 661. A drive crossbar 662 is provided on the drive slider 661 and slidably cooperates with the linkage plate 36.

[0048] Working principle of the power mechanism: When the steel wire is being conveyed normally, the sensing slider 62 of the sensing mechanism 6 maintains a stable position under the action of the steel wire, and the sensing slide rod 65 is also in a relatively static state. At this time, rotating the longitudinal connecting rod 651 and the transverse connecting rod 652 set on the sensing slide rod 65 will not cause the brake slide 441 and the drive slider 661 to move because the sensing slide rod 65 has not moved. The entire power mechanism is in a standby state, the brake mechanism 4 and the linkage mechanism 3 maintain the normal working state, and the take-up cylinder 13 continues to wind up the steel wire.

[0049] Once the steel wire breaks, the sensing slider 62 slides along the sensing carriage 61 under the action of the sensing spring 64, driving the sensing slide rod 65 to move. The movement of the sensing slide rod 65 causes the longitudinal connecting rod 651 rotatably connected to it to rotate. The rotation of the longitudinal connecting rod 651 pushes the drive slider 661 connected to it to slide in the sensing groove 66 on the receiving table 12. As the drive slider 661 slides, the drive crossbar 662 on it slides and engages with the linkage plate 36, causing the linkage plate 36 to rotate around its rotation point on the positioning frame 23. The rotation of the lever 35 causes the linkage fork 35 to move, cutting off the power transmission between the receiving disc 22 and the receiving cylinder 13 in the linkage mechanism 3. At the same time, the transverse connecting rod 652 rotates with the movement of the sensing slide rod 65. Since the transverse connecting rod 652 is rotatably connected to the brake slide 441, its rotation pushes the brake slide 441 to slide along the brake slide groove 44. The sliding of the brake slide 441 drives the brake connecting plate 43 to rotate through the separation plate 442, so that the upper and lower brake plates 42 move towards each other. The upper and lower brake pads 421 tightly clamp the mounting disc 32 to achieve braking of the receiving cylinder 13.

[0050] Combined with appendix Figure 1 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 and attached Figure 10As shown, the wire feeding slider 54 is provided with a fixed slide 57. The clamping mechanism 7 includes a clamping slider 71 slidably disposed on the fixed slide 57. Two clamping sliders 71 are provided. Each clamping slider 71 is provided with a clamping tension spring 72 connected to the other clamping slider 71 on the same side. Each of the two clamping sliders 71 is provided with a unidirectional rotating roller 73. The outer layer of the unidirectional roller 73 is covered with polyurethane rubber. The unidirectional roller 73 rolls and abuts against the steel wire. Multiple telescopic joints 731 are provided at equal intervals along the circumferential direction on the unidirectional roller 73. The unidirectional roller 73 is connected to a unidirectional key 733 through the telescopic joints 731. A unidirectional spring 732 is sleeved on the telescopic joint 731. The two ends of the unidirectional spring 732 are respectively connected to the unidirectional roller 73 and the unidirectional key 733. The clamping slider 71 is provided with a unidirectional tooth 711 that cooperates with the unidirectional key 733.

[0051] Working principle of clamping mechanism 7: When the wire drawing device for stainless steel wire production is running normally, after the wire passes through the guide tube 56 on the wire feeding slider 54, it rolls against the one-way rollers 73 on the two clamping sliders 71. At this time, the one-way key 733 and the one-way tooth 711 on the clamping slider 71 are not engaged, and the one-way roller 73 can rotate freely. The wire can pass smoothly through the clamping mechanism 7 and be wound up smoothly under the rotational pulling force of the take-up cylinder 13.

[0052] Once the steel wire breaks, the take-up cylinder 13 instantly loses the tension of the steel wire and continues to rotate under inertia. At this time, the one-way roller 73, which has detached from the steel wire, begins to rotate in the opposite direction under the drive of the take-up cylinder 13. When the one-way roller 73 rotates in the opposite direction, the one-way key 733 extends along the telescopic joint 731 under the action of the one-way spring 732 and meshes with the one-way teeth 711 on the clamping slider 71. Due to the one-way limiting effect of the one-way teeth 711, the one-way roller 73 is prevented from rotating in the opposite direction, thereby causing the two clamping sliders 71 to lock quickly relative to the fixed slide 57. With the locking of the two clamping sliders 71, the two one-way rollers 73 tightly clamp the steel wire, avoiding problems such as displacement and entanglement of the steel wire due to the inertial rotation of the take-up cylinder 13, thus facilitating subsequent steel wire repair and re-threading.

[0053] In the specific implementation of this invention, the first step is to conduct a pre-start inspection. Check whether the main body of the equipment, such as the wire drawing frame 1 and the receiving table 12, is deformed or damaged, and whether the connection of each component is secure. Check whether the appearance of the motors of the wire drawing mechanism 11, the receiving mechanism 2, and the wire feeding mechanism 5 is intact, and whether the wiring is loose or damaged. Ensure that the motor is properly grounded. Apply an appropriate amount of lubricating oil to the sliding parts such as the wire feeding slide bar 53 and the brake slide groove 44 to ensure smooth operation of the equipment. At the same time, check whether the lubricating oil is sufficient and whether it has deteriorated. Confirm that the receiving cylinder 13 and the mounting plate 32 are tightly connected by bolts, that the linkage plate 34 is properly matched with the receiving plate 22 and the mounting plate 32, and that the sliding key is securely installed. Check whether there are any foreign objects blocking the wide openings at both ends of the guide tube 56 to ensure that the steel wire can pass through smoothly. In addition, check whether the sensing roller 63 and the one-way roller 73 rotate flexibly, and whether the sensing spring 64 and the clamping spring 72 are broken or deformed.

[0054] Next, the stainless steel wire raw material is clamped onto the wire drawing mechanism 11. The parameters of the wire drawing mechanism 11 are adjusted according to the production requirements. The wire drawing mechanism 11 is started to draw the wire into the specified specifications. The drawn wire is passed through the guide tube 56 on the wire feeding slider 54 in sequence, so that the wire rolls and abuts against the sensing roller 63 of the sensing mechanism 6. Then it passes through the gap between the one-way roller 73 on the two clamping sliders 71 and finally winds it onto the take-up cylinder 13 to ensure that the wire is in the correct position between the components and to avoid deviation or jamming.

[0055] During normal production, the wire drawing mechanism 11 is started first. After running stably for a period of time, the motors of the take-up mechanism 2 and the wire feeding mechanism 5 are started in sequence. The motor of the wire feeding mechanism 5 drives the reciprocating screw 52 to rotate, and the wire feeding slider 54 slides back and forth along the wire feeding slider 53 to realize the uniform winding of the steel wire on the take-up cylinder 13. The motor of the take-up mechanism 2 drives the take-up disc 22 to rotate. When the take-up disc 22 rotates, the linkage disc 34, which is matched with it, moves in a circular motion around the linkage slide column 33 in sync with the take-up disc 22 under the action of friction and with the help of the sliding key. The linkage disc 34 transmits power to the mounting disc 32 through the linkage slide column 33, thereby driving the take-up cylinder 13 to wind up the steel wire.

[0056] When the steel wire breaks, the pressure of the steel wire on the sensing roller 63 disappears. The sensing slider 62 slides along the sensing carriage 61 under the action of the sensing spring 64, driving the sensing slide rod 65 to move. The movement of the sensing slide rod 65 causes the longitudinal connecting rod 651 and the transverse connecting rod 652 to rotate. The longitudinal connecting rod 651 pushes the drive slider 661 to slide in the sensing groove 66. The drive crossbar 662 cooperates with the linkage plate 36 to drive the linkage fork 35 to move, causing the linkage plate 34 to disengage from the receiving plate 22 and cutting off the power transmission. The transverse connecting rod 652 pushes the brake carriage 441 along the brake slide. The groove 44 slides, driving the brake connecting plate 43 to rotate through the separation plate 442. The upper and lower brake plates 42 move in opposite directions, clamping the mounting plate 32 and stopping the material receiving cylinder 13 from rotating. Further, the material receiving cylinder 13 continues to rotate under the action of inertia, and the one-way roller 73 of the clamping mechanism 7 rotates in the opposite direction. The one-way key 733 engages with the one-way tooth 711 under the action of the one-way spring 732, locking the two clamping sliders 71. The one-way roller 73 clamps the steel wire, and the operator promptly repairs or re-threads the broken steel wire. After confirming that the equipment is normal, the equipment is restarted according to the startup sequence.
