Description

Technical Field

[0001] This invention relates to the field of metal wire preparation technology, specifically to a drawing device for preparing stainless steel wire rope. Background Technology

[0002] Stainless steel wire rope is a flexible load-bearing component made of multiple strands of high-strength stainless steel wire twisted together. Its superior comprehensive performance makes it important in industrial and engineering fields. Its core material is typically austenitic stainless steel such as 304 or 316, which gives the product excellent corrosion resistance, enabling it to withstand the erosion of the atmosphere, moisture, and various chemical media, making it suitable for harsh conditions such as humid and marine environments. At the same time, stainless steel provides good heat resistance and a certain degree of rust prevention, extending its service life. Structurally, stainless steel wire rope achieves a balance of high strength, high toughness, and good flexibility through a rigorous twisting process (such as point contact, line contact, or surface contact). It features high load-bearing capacity, high safety factor, long service life, and low maintenance requirements. The surface is usually bright and clean, combining aesthetics and practicality.

[0003] In the entire drawing process of stainless steel wire rope production, thorough cleaning of surface oil contaminants is an essential step with far-reaching and continuous impact. Incomplete cleaning will leave residual drawing oil, lubricant, and other contaminants, which will adhere stubbornly to the wire surface. This will directly compromise the effectiveness of subsequent critical processes: during intermediate or final heat treatment requiring high temperatures, the oil contaminants carbonize and decompose at high temperatures, forming carbon deposits and uneven residues that embed or adhere to the wire surface, severely damaging the uniformity of the metal matrix, leading to a significant decrease in surface smoothness, and even the potential for localized corrosion. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a drawing device for preparing stainless steel wire rope, comprising a frame, wherein a liquid storage tank is fixedly mounted on the upper surface of the frame. By setting up the frame and the liquid storage tank, a stable supporting foundation and a cleaning fluid circulation and transportation system are provided for the entire drawing device. The frame supports all functional components and ensures their relative positional accuracy. The liquid storage tank not only stores the cleaning medium but also ensures continuous cleaning operations. The cleaning mechanism is used to remove grease generated during the cold drawing process of stainless steel wire rope. The cleaning mechanism is fixed to the upper surface of the liquid storage tank. As the core clean unit of the device, the cleaning mechanism is responsible for efficiently removing drawing oil, metal debris, and other contaminants adhering to the surface of the stainless steel wire rope during or before the drawing process, ensuring the cleanliness of the wire rope surface and creating conditions for subsequent processes or direct use. A connecting mechanism, used to guide the stainless steel wire rope, is sleeved on the outer surface of the cleaning mechanism. By setting up the connecting mechanism, it serves as a flexible guide and dynamic sealing interface for the wire rope entering and exiting the cleaning area. Its design adapts to the slight vibrations of the wire rope and different wire diameters, guiding the wire rope smoothly through the cleaning area while minimizing leakage of cleaning fluid and the entry of external contaminants. A drawing mechanism is used to draw stainless steel wire rope. A connecting frame is welded to the outer surface of the drawing mechanism and is attached to the outer surface of the machine frame. The drawing mechanism and connecting frame together form the core power unit for plastic deformation processing of the stainless steel wire rope. The connecting frame provides stable installation, and the drawing mechanism provides strong and controllable linear tension, allowing the wire rope to pass through the drawing die to achieve goals such as diameter reduction and hardening. This is a key execution step in the manufacturing process. The cleaning mechanism includes a first connection port that penetrates the upper surface of the liquid storage tank.

[0014] This invention provides a drawing device for manufacturing stainless steel wire rope. It has the following advantages: I. The drawing device for the preparation of stainless steel wire rope, by setting up a cleaning mechanism, is the core clean unit of the device. It is responsible for efficiently removing drawing oil, metal debris and other contaminants adhering to the surface of the stainless steel wire rope during or before the drawing process, ensuring the cleanliness of the wire rope surface and creating conditions for subsequent processes or direct use.

[0015] II. The drawing device for the preparation of stainless steel wire rope, by setting a connecting mechanism, serves as a flexible guide and dynamic sealing interface for the wire rope to enter and exit the cleaning area. Its design adapts to the slight vibration of the wire rope and different wire diameters, and while guiding the wire rope to pass smoothly through the cleaning area, it minimizes the leakage of cleaning fluid and the entry of external pollutants.

[0016] Third, the drawing device used for the preparation of stainless steel wire rope, by setting up a drawing mechanism and a connecting frame, constitutes the core power unit for plastic deformation processing of stainless steel wire rope. It provides a stable installation for the connecting frame and provides a strong and controllable linear tension for the drawing mechanism, so that the wire rope passes through the drawing die to achieve the goals of diameter reduction and hardening. It is a key execution link in the preparation process.

[0017] IV. The drawing device for preparing the stainless steel wire rope, by setting up spring pieces and arc-shaped wrapping strips, together constitutes the basic framework for liquid flow of the cleaning mechanism and the adaptive dynamic sealing end. The first connection port and the first connection box establish a connection with the liquid storage tank. The guide pipe is the core pipe for the flow of cleaning fluid and the passage of wire rope. The spring pieces and arc-shaped wrapping strips at both ends constitute an ingenious adaptive sealing unit: multiple spring pieces with arc-shaped wrapping strips are pressed together at their ends in the natural state to form a nearly closed ring; when the wire rope passes through, the wire rope pushes open the wrapping strip, the spring pieces undergo elastic deformation, and the arc-shaped wrapping strips tightly fit the outer surface of the wire rope to form an effective dynamic seal, which significantly reduces the splashing of cleaning fluid from the pipe port, while allowing the wire rope to pass smoothly and can adapt to a certain range of wire rope diameter changes.

[0018] V. The drawing device for the preparation of stainless steel wire rope, by setting a rotating ring and multiple agitator bars, constitutes a final processing unit for secondary fine stirring and cutting of the cleaning fluid before final outflow. The rotating ring rotates with the upper mechanism. Multiple agitator bars on its lower surface extend into the relatively fixed inner cavity of the rotating ring below. When the rotating ring drives the agitator bars to rotate at high speed, the agitator bars perform a final strong shearing and stirring of the cleaning fluid about to pass through the permeable mesh, which can further break up clumps in the liquid, uniformly mix the agents, and generate finer and more uniform microbubbles or droplets, thereby maximizing the optimization of the physical state of the cleaning fluid and ensuring that it acts on the surface of the wire rope with the best efficiency.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0022] like Figures 1-11 As shown, the present invention provides a technical solution: a drawing device for preparing stainless steel wire rope, including a frame 1, with a liquid storage tank 2 fixed on the upper surface of the frame 1. By setting the frame 1 and the liquid storage tank 2, a stable supporting foundation and a cleaning fluid circulation and transportation system are provided for the entire drawing device. The frame 1 bears all functional components and ensures their relative positional accuracy. The liquid storage tank 2 not only stores the cleaning medium but also provides a guarantee for continuous cleaning operations. The cleaning mechanism 3 is used to remove the grease generated during the cold drawing process of the stainless steel wire rope. The cleaning mechanism 3 is fixed on the upper surface of the liquid storage tank 2. By setting up the cleaning mechanism 3, it is the core clean unit of the device, responsible for efficiently removing drawing oil, metal debris and other contaminants adhering to the surface of the stainless steel wire rope during or before the drawing process, ensuring the cleanliness of the wire rope surface, and creating conditions for subsequent processes such as coating, inspection or direct use. The connecting mechanism 4 is used to guide the stainless steel wire rope. The connecting mechanism 4 is sleeved on the outer surface of the cleaning mechanism 3. By setting the connecting mechanism 4, it serves as a flexible guide and dynamic sealing interface for the wire rope entering and exiting the cleaning area. Its design adapts to the slight vibration of the wire rope and different wire diameters. While guiding the wire rope to pass smoothly through the cleaning area, it minimizes the leakage of cleaning fluid and the entry of external contaminants. The drawing mechanism 6 is used to draw stainless steel wire rope. A connecting frame 5 is welded to the outer surface of the drawing mechanism 6 and is welded to the outer surface of the frame 1. By setting up the drawing mechanism 6 and the connecting frame 5, the core power unit for plastic deformation processing of stainless steel wire rope is formed. The connecting frame 5 provides stable installation, and the drawing mechanism 6 provides strong and controllable linear tension, so that the wire rope passes through the drawing die to achieve the goals of diameter reduction and hardening. It is a key execution link in the manufacturing process. The cleaning mechanism 3 includes a first connection port 31, which penetrates the upper surface of the liquid storage tank 2. A first connection box 32 is fixed at the top of the first connection port 31. A guide tube 33 penetrates the upper surface of the first connection box 32. Limiting blocks 38 are symmetrically welded to the outer surface of the guide tube 33. Several evenly distributed spring pieces 39 are fixed to the outer surfaces of both ends of the guide tube 33. An arc-shaped wrapping strip 310 is fixed to the end of each spring piece 39. The ends of the several arc-shaped wrapping strips 310 are squeezed together in pairs. By setting up a first connection port 31, a first connection box 32, a guide pipe 33, a limiting block 38, a spring 39, and an arc-shaped wrapping strip 310, the liquid flow basic framework and adaptive dynamic sealing end of the cleaning mechanism 3 are formed. The first connection port 31 and the first connection box 32 establish communication with the liquid storage tank 2. The guide pipe 33 is the core pipe for the flow of cleaning fluid and the passage of the wire rope. The spring 39 and the arc-shaped wrapping strip 310 at both ends form an ingenious adaptive sealing unit: multiple spring 39 with arc-shaped wrapping strips 310 are pressed together at their ends in the natural state to form a nearly closed ring; when the wire rope passes through, the wire rope pushes open the wrapping strip, the spring 39 undergoes elastic deformation, and the arc-shaped wrapping strip 310 tightly fits the outer surface of the wire rope to form an effective dynamic seal, which significantly reduces the splashing of cleaning fluid from the pipe port, while allowing the wire rope to pass smoothly and can adapt to a certain range of wire rope diameter changes.

[0023] A second connecting box 34 penetrates the upper surface of the guide pipe 33, and a spray tank 35 penetrates the upper surface of the second connecting box 34. An inlet 36 penetrates the outer surface of the spray tank 35, and a connecting pipe 311 is fixedly installed at the opening of the inlet 36. The end of the connecting pipe 311 away from the inlet 36 penetrates the outer surface of the storage tank 2 and extends to the bottom of the inner cavity of the storage tank 2. By setting up the second connecting box 34, the spray tank 35, the inlet 36, and the connecting pipe 311, a three-dimensional, enhanced cleaning fluid injection and circulation pressurization system is formed. The second connecting box 34 serves as an intermediate transition chamber, connecting the upper and lower components. The spray tank 35 is the distribution and pressurization chamber for the high-speed cleaning fluid. The inlet 36 is the entrance for the cleaning fluid into the spray tank 35. The connecting pipe 311 directly pumps the cleaning fluid from the bottom of the storage tank 2 to the spray tank 35, ensuring continuous supply and sufficient pressure. This structure allows the cleaning fluid to be injected from the side and above the guide tube 33, forming a swirling scouring or precise spray on the wire rope passing through it, improving the cleaning coverage and impact.

[0024] A spraying mechanism 37 is installed inside the spray tank 35. The spraying mechanism 37 includes a stepper motor 371, which is fixed to the top of the inner wall of the spray tank 35. A rotating rod 372 is mounted on the output end of the stepper motor 371 via a coupling. A rotating frame 373 is welded to the bottom end of the rotating rod 372. Several evenly distributed spiral blades 374 are fixed on the outer surface of the rotating frame 373. The spiral blades 374 are rotatably connected to the inner cavity of the spray tank 35. By setting up the stepper motor 371, rotating rod 372, rotating frame 373, and spiral blades 374, a fluid pressurization and turbulence generator is formed inside the spray tank 35. The stepper motor 371 provides power with controllable rotation speed. The rotating rod 372 transmits torque. The rotating frame 373 serves as the mounting base for the spiral blades 374. Multiple spiral blades 374 rotate at high speed inside the spray tank 35, functioning similarly to the impeller or agitator of a centrifugal pump: on the one hand, they pressurize the cleaning fluid flowing in from the inlet 36, increasing its spray speed and kinetic energy; on the other hand, the rotation of the spiral blades 374 generates strong eddies and turbulence inside the tank, ensuring that the cleaning fluid is fully stirred and mixed evenly, and may entrain air to form microbubbles, enhancing the chemical activity and physical scouring effect of the cleaning fluid, providing a power guarantee for efficient cleaning; at the same time, they can draw the cleaning fluid from the inner cavity of the storage tank 2 into the inner cavity of the spray tank 35.

[0025] A ventilator 375 is welded to the bottom of the rotating frame 373. A connecting frame 376 is welded to the bottom of the ventilator 375. A rotating ring 377 is welded to the lower surface of the connecting frame 376. A first rolling bearing 378 is fixed to the outer surface of the rotating ring 377. The outer ring of the first rolling bearing 378 is fixed to the lower surface of the spray box 35. A connecting ring 379 is welded to the lower surface of the spray box 35. A water-permeable mesh 3710 is fixed to the inner wall of the connecting ring 379. The water-permeable mesh 3710 is located in the inner cavity of the second connecting box 34. By setting up the ventilator 375, connecting frame 376, rotating ring 377, first rolling bearing 378, connecting ring 379, and water-permeable mesh 3710, a stable support, sealing transition, and final flow channel control interface for the rotating component are formed. The ventilator 375 serves as an auxiliary channel. The connecting frame 376 connects the upper and lower components. The rotating ring 377 is a key rotating component. The first rolling bearing 378 provides high-precision rotational support for the rotating ring 377, ensuring its smooth operation. The connecting ring 379 fixes the permeable mesh 3710. The permeable mesh 3710 is the final control grid for the cleaning fluid to enter the second connecting box 34 and the guide pipe 33 below from the spray tank 35. Its dense mesh structure can further homogenize the water flow, break up any large air bubbles, and play a final filtering role, preventing impurities from entering the wire rope cleaning area. At the same time, its fixed installation method ensures the stability of the flow field below.

[0026] A rotating ring 3711 is fixedly mounted on the top of the inner cavity of the connecting frame 376. Agitating strips 3712 are fixedly mounted on the lower surface of the rotating ring 3711. Several agitating strips 3712 are evenly distributed and rotatably connected to the inner cavity of the rotating ring 377. By setting the rotating ring 3711 and multiple agitating strips 3712, a final-stage treatment unit is formed to perform secondary fine stirring and cutting of the cleaning fluid before final outflow. The rotating ring 3711 rotates with the upper mechanism. Multiple agitating strips 3712 on its lower surface extend into the relatively fixed inner cavity of the rotating ring 377 below. When the rotating ring 3711 drives the stirring bar 3712 to rotate at high speed, the stirring bar 3712 performs a final strong shearing and stirring on the cleaning fluid that is about to pass through the permeable net 3710. This further breaks up the clumps in the liquid, mixes the agent evenly, and generates finer and more uniform microbubbles or droplets, thereby maximizing the optimization of the physical state of the cleaning fluid and ensuring that it acts on the surface of the wire rope with the best efficiency.

[0027] The connecting mechanism 4 includes a swaying frame 41, with a wrapping ring 42 symmetrically extending through its outer surface. The wrapping ring 42 is fitted onto the outer surface of the limiting block 38, and a second rolling bearing 43 is fixed to the inner wall of the wrapping ring 42. The inner ring of the second rolling bearing 43 is fixed to the outer surface of the limiting block 38. By setting the swaying frame 41, the wrapping ring 42, and the second rolling bearing 43, a floating connection and multi-degree-of-freedom compensation system is formed between the connecting mechanism 4 and the cleaning mechanism 3. The swaying frame 41 is the main frame of the connecting mechanism 4. The wrapping ring 42 is fitted onto the limiting block 38 outside the guide tube 33 of the cleaning mechanism 3 via the internal second rolling bearing 43. The second rolling bearing 43 allows the wrapping ring 42 and the entire swaying frame 41 to swing or rotate flexibly within a certain angle range relative to the limiting block 38. This design allows the connecting mechanism 4 to adapt to the slight lateral force or vibration generated when the wire rope enters or exits, avoiding rigid constraints that could lead to wire rope scratches or seal failure, while ensuring the stability of its guiding function.

[0028] Guide cylinders 44 are symmetrically fixed at both ends of the swaying frame 41. These guide cylinders 44 guide the stainless steel wire rope. A limiting cylinder 47 penetrates the outer surface of the guide cylinder 44. A sliding rod 48 is slidably connected to the inner cavity of the limiting cylinder 47. A second spring 49 is sleeved on the outer surface of the sliding rod 48, and its end is fixed to the inner wall of the limiting cylinder 47. An arc-shaped strip 410 is fixed to one end of the sliding rod 48 located within the inner cavity of the guide cylinder 44, and a rubber pad 411 is fixed to the inner wall of the arc-shaped strip 410. By configuring the guide cylinder 44, limiting cylinder 47, sliding rod 48, second spring 49, arc-shaped strip 410, and rubber pad 411, a precision centering and guiding mechanism with flexible clamping and anti-jumping capability for the wire rope is formed. The guide cylinder 44 provides the main channel. The limiting cylinder 47 provides precise radial movement guidance for the sliding rod 48. The sliding rod 48 is the actuator. The second spring 49 provides a constant, adjustable radial clamping force. The shape of the arc-shaped bar 410 matches the outer circle of the wire rope. The rubber pad 411 on its inner wall provides a flexible, high-friction contact surface. Multiple such components are symmetrically arranged inside the guide cylinder 44. Under the action of spring force, the rubber pad 411 on the arc-shaped bar 410 gently hugs the wire rope from all sides, achieving automatic centering. This effectively suppresses radial runout, vibration, or rotation that may occur in the wire rope during high-speed pulling or cleaning, ensuring that it always moves smoothly along the axis. This is crucial for ensuring cleaning uniformity and pulling quality.

[0029] A first spring 45 is fixed to the lower surface of the guide cylinder 44, and a support frame 46 is welded to the bottom end of the first spring 45. The support frame 46 is welded to the outer surface of the liquid storage tank 2. By setting the first spring 45 and the support frame 46, a vertical elastic suspension and vibration damping system is formed for the entire connecting mechanism 4. The support frame 46 provides a fixed fulcrum. The first spring 45 connects the support frame 46 and the guide cylinder 44. This suspension design allows the entire guide cylinder 44 assembly to have a certain elastic floating space in the vertical direction, which can absorb and buffer the periodic tension changes from the vertical shaking or pulling process of the wire rope, prevent vibration from being directly transmitted to the rigid sealing part of the cleaning mechanism 3, further protect the reliability of the dynamic seal, and improve the smoothness of the wire rope operation.

[0030] The drawing mechanism 6 includes a hydraulic cylinder 62, which is fixed to the inner wall of the connecting frame 5. A bent rod 63 is provided at the output end of the hydraulic cylinder 62. A fixed frame 64 is fixed to the upper surface of the connecting frame 5, and a guide plate 65 is fixed to the end of the fixed frame 64. The guide plate 65 is inclined, and a track groove is formed on its outer surface. A guide ring 66 is fixed to the outer surface of the guide plate 65. The hydraulic cylinder 62, bent rod 63, fixed frame 64, guide plate 65, and guide ring 66 constitute the core mechanical structure for drawing execution and guidance. The hydraulic cylinder 62 provides a powerful, stable, and precisely controllable linear power source for the drawing force. The bent rod 63 converts and transmits the linear motion of the piston in the hydraulic cylinder 62. The fixed frame 64 provides stable support for the guide plate 65. The inclined design of the guide plate 65 and the track grooves on its surface provide a precise inclined guide trajectory for the movement of the clamping mechanism, efficiently converting the horizontal or vertical driving force provided by the hydraulic cylinder 62 into axial tensile force on the wire rope. The guide ring 66 is used to guide the wire rope into the clamping point and as an auxiliary limiter, ensuring that the wire rope maintains the correct angle with the clamping point during the pulling process and reducing additional bending stress.

[0031] A sliding block 67 is fixedly mounted on the end of the bent rod 63 away from the hydraulic cylinder 62. The sliding block 67 is slidably connected to a track groove opened on the outer surface of the guide plate 65. A cylinder 68 is welded to the outer surface of the sliding block 67. An elastic pad 610 is fixedly mounted on the inner wall of the cylinder 68. An inclined plate 611 is fixedly mounted on the outer surface of the elastic pad 610. An anti-slip strip is provided at the end of the inclined plate 611 away from the elastic pad 610. A blocking ring 69 is fixedly mounted on the inner wall of the cylinder 68. The blocking ring 69 is pressed and adapted to the upper surface of the inclined plate 611. By setting the sliding block 67, cylinder 68, blocking ring 69, elastic pad 610, and inclined plate 611, an intelligent gripper mechanism that directly clamps and pulls the wire rope is formed. The sliding block 67 slides downward along the inclined surface of the guide plate 65. The cylinder 68 is the gripper body. Multiple inclined plates 611 inside are mounted on the cylinder wall through the elastic pad 610 and can swing slightly radially. The anti-slip strip at the inner end of the inclined plate 611 directly contacts the wire rope. The barrier ring 69 is fixed to the upper part of the inner wall of the cylinder 68. When the hydraulic cylinder 62 pulls the bent rod 63 and the entire gripper mechanism to slide downward along the inclined plane, i.e., to perform the pulling action, the upper surface of the inclined plate 611 is blocked by the barrier ring 69. Under the decomposition of the reaction force of the inclined plane, the inclined plate 611 is subjected to a component force that squeezes towards the center of the cylinder 68, forcing it to rotate inward around the hinge point of the elastic pad 610, thereby making the anti-slip strip tightly grip the wire rope, generating a huge frictional force to pull the wire rope. When the hydraulic cylinder 62 moves in the opposite direction and the gripper returns, the direction of the force changes, and the inclined plate 611 automatically releases the wire rope under the restoring force of the elastic pad 610 or the structural design. This self-locking wedge clamping principle of "the tighter it gets, the better" requires no additional clamping power, has a simple and reliable structure, and the clamping force is positively correlated with the pulling force, ensuring that the wire rope does not slip or get damaged during the pulling process.

[0032] Working principle: The operator introduces a stainless steel wire rope, coated with drawing grease from the previous process, from one side of the device. The wire rope first passes through the guide cylinder 44 at one end of the connecting mechanism 4. Inside the cylinder, multiple sets of arc-shaped bars 410, provided with constant pressure by second springs 49, and their rubber pads 411 gently embrace the wire rope from all sides, achieving automatic centering and initial stabilization. Subsequently, the wire rope enters the guide tube 33 of the cleaning mechanism 3, pushing open the arc-shaped wrapping bar 310 supported by spring pieces 39 at its port, forming a dynamic seal and passing through it. Next, the wire rope continues to pass through the guide cylinder 44 and the connecting mechanism 4 on the other side, finally entering the gripper area of ​​the cylinder 68 of the drawing mechanism 6, and passing through the drawing die. After the threading is completed, the stepper motor 371 of the cleaning mechanism 3 starts, and the cleaning fluid is pumped into the spray tank 35 through the connecting tube 311; Inside the spray tank 35, a stepper motor 371 drives a rotating rod 372 and a rotating frame 373 to rotate at high speed, with spiral blades 374 on them violently agitating and pressurizing the cleaning fluid. The rotational power continues to be transmitted downwards, driving the agitator strip 3712 at the end to rotate at high speed within the rotating ring 377 via the vent 375 and connecting frame 376, performing final shearing on the liquid. The multi-stage enhanced cleaning fluid forms a uniform, highly turbulent active fluid. Under pressure, it flows evenly through a permeable mesh 3710 and enters the second connecting tank 34, then is injected into the guide pipe 33. At this point, the high-speed flowing cleaning fluid, within the sealed space of the guide pipe 33, powerfully washes the outer surface of the continuously moving stainless steel wire rope from all directions. The cleaning fluid penetrates and emulsifies the pulling grease and adhering particles on the surface of the wire rope. Waste liquid containing contaminants flows back to the storage tank 2 from the first connecting port 31 at the bottom of the guide pipe 33, and is recycled after filtration and sedimentation. The entire cleaning process is carried out online simultaneously with the pulling motion; The drawing operation begins. The hydraulic cylinder 62 of the drawing mechanism 6 is activated, its piston rod pulling the sliding block 67 downwards along the track groove on the inclined guide plate 65 via the bent rod 63. The cylinder 68 welded to the sliding block 67 and its internal clamping assembly move accordingly. Because the retaining ring 69 on the inner wall of the cylinder 68 obstructs the free movement of the upper end of the inclined plate 611, as the cylinder 68 moves downwards along the incline, the reaction force of the incline decomposes into a radial component that forces multiple inclined plates 611 to rotate towards the center with their root elastic pads 610 as the fulcrum. The portion of the inclined plate 611 with anti-slip strips presses tightly against the stainless steel wire rope passing through it, generating enormous static friction and creating a self-locking effect of "the tighter it gets, the more it gets pulled." The hydraulic cylinder 62 continuously provides a stable pulling force, which powerfully pulls the wire rope through the drawing die. The die causes plastic deformation of the wire rope, reducing its diameter and increasing its length, thus improving its mechanical properties. During the drawing process, the connecting mechanism 4 effectively absorbs the vibration of the wire rope through the suspension of its first spring 45 and the floating connection of its second rolling bearing 43, and keeps the wire rope axis stable through the constant pressure clamping member in its guide cylinder 44, ensuring that the drawing force is applied evenly to the wire rope. When a drawing stroke ends, hydraulic cylinder 62 reverses direction, piston rod retracts, and pushes bent rod 63 and sliding block 67 to slide upwards along the inclined surface of guide plate 65 for the return stroke. At this time, the direction of the force acting on inclined plate 611 changes, and the radial clamping force disappears. Under the elastic restoring force of elastic pad 610 and possible inclined surface geometry, inclined plate 611 automatically opens slightly outwards, releasing the clamp on the wire rope. The gripper is not driven to the wire rope during the return stroke. At the same time, the preceding wire feeding system continues to supply wire rope, and cleaning mechanism 3 continues to work. When the gripper returns to the starting position, hydraulic cylinder 62 starts again to begin the next drawing stroke, and the gripper self-locks again and pulls the wire rope forward. This cycle repeats, realizing continuous and clean drawing production of stainless steel wire rope. The clean wire rope is output from the other side of the device to enter the next process or be wound into a coil.
