Description

Technical Field

[0001] This invention relates to the technical field of wire drawing machines, specifically a straight-feed wire drawing machine with integrated wire breakage clamping. Background Technology

[0002] Medical stainless steel wire drawing machines, as core equipment for precision wire processing, are widely used in the production of raw materials for high-value medical devices such as cardiovascular stent guidewires, surgical suture needles, and orthopedic Kirschner wires. These machines perform continuous, multi-pass drawing, during which the wire must pass through cemented carbide die holes at high speed, enduring enormous drawing stress and plastic deformation.

[0003] When the wire passes through the die hole, it is prone to sudden fracture due to local stress concentration caused by rapid cross-sectional contraction, dry friction and heating caused by insufficient lubrication during drawing, or defects such as non-metallic inclusions in the material itself. At the moment of fracture, the stored elastic potential energy will be converted into high-speed rebound kinetic energy, causing the broken wire to be flung out in a whip shape, causing an accident.

[0004] Existing wire drawing machines are generally equipped with pneumatic or hydraulic wire breakage clamping mechanisms. Their original design intention is to drive the clamping blocks to close within milliseconds after detecting a wire breakage signal, and capture the high-speed retracting wire through mechanical friction braking. However, directly using the clamping blocks to capture the wire will cause the high-speed moving wire to slide violently on the surface of the clamping blocks, generating high temperatures or even sparks, which may prevent the clamping blocks from effectively capturing the retracting wire. If the clamping force is forcibly increased to overcome the sliding, the instantaneous peak stress will exceed the local strength of the wire, causing the wire to be "crushed" rather than clamped at the clamping point, and the broken end will fly off with the remaining kinetic energy. Existing wire breakage clamping measures are prone to making it difficult to control the clamping force due to the excessive retraction kinetic energy of the wire, resulting in an unsatisfactory success rate in capturing the wire. Summary of the Invention

[0005] The purpose of this invention is to provide a straight-line wire drawing machine with integrated wire breakage clamping to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A straight-line wire drawing machine with integrated wire breakage clamping includes a frame and multiple sets of drawing components disposed on the frame. The drawing components include two boxes fixed on the frame and a mold that is fixedly connected to the two boxes. The mold has a die hole that connects the two boxes.

[0008] Each of the two housings is equipped with a set of wire breakage clamping structures, which include:

[0009] A trigger wheel is located inside the housing, and the trigger wheel is connected to an elastic mechanism located inside the housing;

[0010] The two rotating shafts installed in the housing and the horizontal tube fixed between the two rotating shafts are rotated. The wire passes through the housing, the mold and the horizontal tube, and moves in a straight state, so that the elastic mechanism can maintain the elastic potential energy reserve state.

[0011] The clamping mechanism on the horizontal tube releases elastic potential energy when the wire breaks in the mold, causing the trigger wheel to move down. The elastic mechanism can also drive the rotating shaft to drive the horizontal tube to perform a swinging motion. The clamping mechanism is triggered in the latter part of the swinging motion of the horizontal tube to perform a clamping motion on the wire.

[0012] As described above, the integrated wire breakage clamping straight-line wire drawing machine includes an elastic mechanism comprising a horizontal arm movably disposed in the housing and two sets of elastic elements connected to the horizontal arm. The trigger wheel is rotatably mounted at the bottom of the horizontal arm. The horizontal arm is also connected to two rotating shafts via two sets of transmission components. When the trigger wheel moves down, it can cause the horizontal arm to drive the two rotating shafts via the two sets of transmission components to perform a swaying motion on the horizontal tube.

[0013] As described above, the integrated wire breakage clamping straight-line wire drawing machine includes a fixed block fixed in the housing, a guide post fixedly installed at the bottom of the fixed block, and a first cylindrical spring sleeved on the outer periphery of the guide post. The cross arm is slidably connected to the guide post, and the two ends of the first cylindrical spring are respectively connected to the cross arm and the fixed block.

[0014] As described above, the integrated wire breakage clamping straight-line wire drawing machine includes a transmission assembly comprising a transmission arm fixedly mounted on the rotating shaft and a follower arm fixedly connected to the cross arm.

[0015] The follower arm has a drive column fixedly provided at one end away from the cross arm, and the transmission arm has a strip-shaped through groove adapted to the drive column along its own length direction. The drive column passes through the strip-shaped through groove and is slidably connected to the transmission arm.

[0016] The integrated wire breakage clamping straight-line wire drawing machine as described above: the clamping mechanism includes:

[0017] A drive arm is slidably disposed on the horizontal tube and capable of moving radially along the horizontal tube. An elastic trigger is also connected between the drive arm and the horizontal tube. A clamping member is provided on one end of the drive arm located inside the horizontal tube.

[0018] A rolling engagement assembly is disposed on the horizontal tube and cooperates with the drive arm. The rolling engagement assembly is movable along the axial direction of the horizontal tube, causing the elastic trigger to drive the drive arm to move radially relative to the horizontal tube, so that the clamping member performs a clamping action on the wire.

[0019] As described above, the integrated wire breakage clamping straight-line wire drawing machine includes two columns fixed to the outer wall of the horizontal tube and located on both sides of the drive arm, and two second columnar springs respectively sleeved on the outer periphery of the two columns.

[0020] The drive arm has a movable plate fixed at one end outside the horizontal tube. The movable plate is slidably connected to the two columns. One end of the second columnar spring is connected to the movable plate, and the other end is connected to a frustum fixed at one end of the column away from the horizontal tube.

[0021] As described above, the integrated wire breakage clamping straight-line wire drawing machine has the following features: the drive arm is provided with a mounting groove, a circular roller is rotatably mounted in the mounting groove, and the rolling engagement assembly includes a guide rail fixed to the outer wall of the horizontal tube and arranged along the axial direction of the horizontal tube, and a movable seat slidably fitted on the guide rail, with a limiting plate fixedly provided on the movable seat.

[0022] The limiting plate extends into the mounting groove, is located below the roller and abuts against the roller. The movable seat is connected to a rolling guide assembly, which enables the movable seat to slide away from the drive arm on the guide rail, so that the limiting plate is pulled out of the mounting groove.

[0023] As described above, the integrated wire breakage clamping straight-line wire drawing machine includes a rolling guide assembly, which is fixedly installed in the housing. An arc-shaped arm is fixed on each side of the movable seat. A guide wheel is rotatably installed at the end of the arc-shaped arm away from the movable seat. The guide plate is provided with a guide groove that matches the guide wheel. The guide wheel is rotatably disposed in the guide groove.

[0024] The guide groove includes an arc-shaped through groove and a straight through groove connected together. The central axis of the arc-shaped through groove and the rotating shaft coincide. When the wire breaks and the horizontal tube swings, the guide wheel rolls in the straight through groove, which can cause the arc-shaped arm to drive the movable seat away from the drive arm to slide.

[0025] As described above, the integrated wire breakage clamping straight-line wire drawing machine has a shaft fixed at one end of the drive arm located inside the horizontal tube. The clamping member includes a first assembly arm and a second assembly arm that are rotatably connected to the shaft. The first assembly arm and the second assembly arm are symmetrically distributed in the horizontal tube, and each of them has a roller at the end away from the shaft. The roller is rolled and fitted into an arc-shaped slide rail provided on the inner wall of the horizontal tube.

[0026] The first assembly arm and the second assembly arm are respectively fixedly connected by a connecting strip to a plurality of first grippers and a plurality of second grippers, and the plurality of first grippers and the plurality of second grippers are distributed alternately.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] This invention, by setting a trigger wheel, limits the trigger wheel when the wire is not broken, keeping it in an upward state while the first cylindrical spring remains compressed. When the wire breaks, it can no longer limit the trigger wheel, causing the first cylindrical spring to rebound. This rebound allows the horizontal arm and follower arm to move downward, causing the horizontal tube to perform a swaying motion. The swaying of the horizontal tube effectively interferes with the wire's retraction path, absorbing and dissipating the wire's retraction kinetic energy. This facilitates the clamping mechanism's successful capture of the wire and avoids the problem of excessive clamping difficulty due to excessive wire retraction kinetic energy.

[0029] Secondly, because the first and second grippers are staggered, an axial force can be applied to the wire during clamping. Compared with using clamping blocks to clamp the wire, this effectively reduces the risk of slippage and makes the reliability of effective clamping higher. Moreover, compared with using two clamping blocks that move in opposite directions, the channel formed by the first and second grippers for the wire to pass through gradually narrows when clamping, eventually clamping the wire. Therefore, the narrowing of the channel enables the wire to be positioned while achieving the wire clamping function, avoiding the problem of uneven clamping force caused by height differences between different parts of the wire in the clamping components.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0044] Please see Figures 1-11In this embodiment, a straight-line wire drawing machine with integrated wire breakage clamping includes a frame 1 and multiple sets of drawing components disposed on the frame 1. The drawing components include two boxes 2 fixed on the frame 1 and a mold 3 fixedly connecting the two boxes 2. The mold 3 is provided with a mold hole that communicates with the two boxes 2.

[0045] Each of the two housings 2 is equipped with a set of wire breakage clamping structures, which include:

[0046] A trigger wheel 4 is provided in the housing 2, and the trigger wheel 4 is connected to an elastic mechanism provided in the housing 2;

[0047] The two rotating shafts 11 installed in the housing 2 and the horizontal tube 12 fixedly installed between the two rotating shafts 11 are rotated. The wire passes through the housing 2, the mold 3 and the horizontal tube 12, and moves in a straight state, so that the elastic mechanism maintains the elastic potential energy storage state.

[0048] When the wire breaks in the mold 3, the clamping mechanism on the horizontal tube 12 releases elastic potential energy, causing the trigger wheel 4 to move down. The elastic mechanism can also drive the rotating shaft 11 to drive the horizontal tube 12 to perform a swinging motion. The clamping mechanism is triggered in the latter part of the swinging motion of the horizontal tube 12 to perform a clamping motion on the wire.

[0049] In this embodiment, it should be noted that both of the boxes 2 are provided with holes for wires to pass through on the side away from the mold 3. Furthermore, the end of the horizontal tube 12 is provided with a through-hole 1201 for wires to pass through. It should be pointed out that the diameters of the holes and the through-hole 1201 are both larger than the diameter of the wires before and after being drawn.

[0050] With attachment Figure 3 Taking the state shown as an example, this is the working state when the wire breakage has not occurred. The wire is in contact with the trigger wheel 4, and under the action of the wire being taut, the elastic mechanism stores elastic potential energy, and the horizontal tube 12 is in a horizontal position.

[0051] When the wire breaks, the elastic mechanism releases its elastic potential energy, causing the trigger wheel 4 to move downward in the housing 2. At the same time, the elastic mechanism drives the rotating shaft 11 to drive the horizontal tube 12 to perform a swinging action. The swinging of the horizontal tube 12 can interfere with the wire's retraction path and has a dissipating and absorbing effect on the wire's retraction kinetic energy. During the latter part of the swinging stroke, the clamping mechanism is triggered to clamp the wire.

[0052] As a further embodiment of the present invention, please refer again. Figure 8The elastic mechanism includes a horizontal arm 8 movably disposed in the housing 2 and two sets of elastic elements connected to the horizontal arm 8. The trigger wheel 4 is rotatably mounted at the bottom of the horizontal arm 8. The horizontal arm 8 is also connected to two rotating shafts 11 respectively through two sets of transmission components. When the trigger wheel 4 moves down, it can cause the horizontal arm 8 to drive the two rotating shafts 11 through the two sets of transmission components to drive the horizontal tube 12 to perform a swinging action.

[0053] Furthermore, the outer wall of the trigger wheel 4 is provided with a groove. After the wire passes through the housing 2, it passes under the trigger wheel 4. When the wire is tightened, it enters the groove on the trigger wheel 4, causing the trigger wheel 4 to rise. The elastic element stores elastic potential energy.

[0054] The elastic element includes a fixing block 5 fixed in the housing 2, a guide post 6 fixedly installed at the bottom of the fixing block 5, and a first columnar spring 7 sleeved on the outer periphery of the guide post 6. The cross arm 8 is slidably connected to the guide post 6, and the two ends of the first columnar spring 7 are respectively connected to the cross arm 8 and the fixing block 5.

[0055] As a further embodiment of the present invention, please refer again. Figure 6 , Figure 8 as well as Figure 9 The transmission assembly includes a transmission arm 13 fixedly mounted on the rotating shaft 11 and a follower arm 9 fixedly connected to the cross arm 8; wherein, a drive column 10 is fixedly provided at one end of the follower arm 9 away from the cross arm 8, and a strip-shaped through groove 1301 adapted to the drive column 10 is provided on the transmission arm 13 along its own length direction, and the drive column 10 passes through the strip-shaped through groove 1301 and is slidably connected to the transmission arm 13.

[0056] In this embodiment, when the wire breaks inside the die hole, the tension of the wire ends, and the first columnar spring 7 rebounds, causing the horizontal arm 8 to slide downward on the guide post 6. Correspondingly, the follower arm 9 moves together with the horizontal arm 8, and the drive post 10 slides with the transmission arm 13 through the strip groove 1301, thereby causing the transmission arm 13 to drive the rotating shaft 11 to rotate, that is, the horizontal tube 12 wobbles.

[0057] With attachment Figure 3 Taking the state shown as an example (left box 2), specifically, the follower arm 9 moves down with the horizontal arm 8, and the drive column 10 drives the transmission arm 13 to deflect clockwise through the strip groove 1301. As a result, the horizontal tube 12 swings clockwise.

[0058] To address this, the present invention addresses the issue by configuring the trigger wheel 4. When no wire breakage occurs, the taut wire limits the trigger wheel 4, keeping it in an upward state. The first cylindrical spring 7 remains compressed. When the wire breaks, it can no longer limit the trigger wheel 4, causing the first cylindrical spring 7 to rebound. This rebound allows the horizontal arm 8 and the follower arm 9 to move downward, causing the horizontal tube 12 to perform a swaying motion. The swaying of the horizontal tube 12 effectively interferes with the wire's retraction path, absorbing and dissipating the wire's retraction kinetic energy. This facilitates the clamping mechanism's successful capture of the wire, avoiding the problem of excessive clamping difficulty due to excessive wire retraction kinetic energy.

[0059] As a further embodiment of the present invention, please refer again. Figure 6 and Figure 10 The clamping mechanism includes:

[0060] A drive arm 17 is slidably disposed on the horizontal tube 12 and is capable of moving radially along the horizontal tube 12. An elastic trigger is also connected between the drive arm 17 and the horizontal tube 12. A clamping member is provided on one end of the drive arm 17 located inside the horizontal tube 12.

[0061] A rolling engagement assembly is provided on the horizontal tube 12 and cooperates with the drive arm 17. The rolling engagement assembly is movable along the axial direction of the horizontal tube 12, causing the elastic trigger to drive the drive arm 17 to move radially relative to the horizontal tube 12, so that the clamping member performs a clamping action on the wire.

[0062] In this embodiment, when the wire breaks, under the rebound action of the first cylindrical spring 7, the horizontal arm 8 and the trigger wheel 4 move downward, causing the horizontal tube 12 to swing. During the latter part of the swing of the horizontal tube 12, the rolling engagement assembly moves along the axial direction of the horizontal tube 12, causing the elastic trigger to release its elastic potential energy. The elastic trigger drives the drive arm 17 to slide radially toward the inside of the horizontal tube 12, thereby causing the clamping member to perform a clamping action on the wire.

[0063] Therefore, through mechanical linkage control, when the wire breaks, the swaying action of the horizontal tube 12 and the clamping action of the clamping member on the wire can be carried out in an orderly sequence. That is, by using the swaying of the horizontal tube 12, the retraction path of the wire can be interfered with, which has the effect of consuming and absorbing the retraction kinetic energy of the wire. Then, after the horizontal tube 12 sways for a period of time, the clamping member performs the clamping action on the wire with the kinetic energy consumed. This can achieve effective capture of the wire and avoid the problem of high capture difficulty due to excessive retraction kinetic energy of the wire.

[0064] As a further embodiment of the present invention, please refer again. Figure 6 The elastic trigger includes two columns 14 fixed to the outer wall of the horizontal tube 12 and located on both sides of the drive arm 17, and two second columnar springs 15 respectively sleeved on the outer periphery of the two columns 14; wherein, a movable plate 16 is fixed to one end of the drive arm 17 outside the horizontal tube 12, the movable plate 16 is slidably connected to the two columns 14, one end of the second columnar spring 15 is connected to the movable plate 16, and the other end is connected to a frustum 1401 fixed to one end of the column 14 away from the horizontal tube 12.

[0065] As a further embodiment of the present invention, please refer again. Figure 6 and Figure 8 The drive arm 17 is provided with a mounting groove, in which a circular roller 21 is rotatably mounted. The rolling engagement assembly includes a guide rail 19 fixed to the outer wall of the horizontal tube 12 and arranged along the axial direction of the horizontal tube 12, and a movable seat 20 slidably fitted on the guide rail 19. A limiting plate 2001 is fixedly provided on the movable seat 20. The limiting plate 2001 extends into the mounting groove, is located at the lower part of the circular roller 21 and abuts against the circular roller 21. The movable seat 20 is connected to a rolling guide assembly, which can cause the movable seat 20 to slide away from the drive arm 17 on the guide rail 19, so that the limiting plate 2001 is pulled out from the mounting groove.

[0066] The rolling guide assembly includes a guide plate 23 fixedly installed in the housing 2. An arc-shaped arm 22 is fixed on each side of the movable seat 20. A guide wheel 24 is rotatably mounted on the end of the arc-shaped arm 22 away from the movable seat 20. The guide plate 23 is provided with a guide groove adapted to the guide wheel 24. The guide wheel 24 is rolled in the guide groove. The guide groove includes an arc-shaped through groove 2301 and a straight through groove 2302 connected together. The arc-shaped through groove 2301 and the central axis of the rotating shaft 11 coincide. When the wire breaks and the horizontal tube 12 swings, the guide wheel 24 rolls in the straight through groove 2302, which can cause the arc-shaped arm 22 to drive the movable seat 20 away from the drive arm 17 to slide.

[0067] In this embodiment, when the wire breaks, as the rotating shaft 11 causes the horizontal tube 12 to sway, the guide wheel 24 rolls sequentially in the arc-shaped through groove 2301 and the straight through groove 2302.

[0068] Specifically, when the guide wheel 24 rolls in the arc-shaped through groove 2301, since the central axis of the arc-shaped through groove 2301 and the rotating shaft 11 coincide, the guide wheel 24, the arc-shaped arm 22, and the movable seat 20 remain relatively stationary with the horizontal tube 12, the limiting plate 2001 abuts against the circular roller 21, and the limiting plate 2001 limits the circular roller 21, so that the second columnar spring 15 remains in a compressed state;

[0069] When the guide wheel 24 enters the straight through groove 2302, the guide wheel 24 will roll with the guide plate 23 through the straight through groove 2302, causing the arc arm 22 to drive the movable seat 20 to slide away from the drive arm 17 on the guide rail 19. Finally, the limiting plate 2001 is pulled out from the mounting groove and disengaged from the roller 21. Then, the second columnar spring 15 will rebound, causing the drive arm 17 to slide towards the inside of the horizontal tube 12, causing the clamping member to clamp the wire that has absorbed the kinetic energy of the pullback.

[0070] As a further embodiment of the present invention, please refer again. Figure 7 , Figure 9 , Figure 10 as well as Figure 11 The drive arm 17 is fixed with a shaft 25 at one end inside the horizontal tube 12. The clamping member includes a first assembly arm 26 and a second assembly arm 27 rotatably connected to the shaft 25. The first assembly arm 26 and the second assembly arm 27 are symmetrically distributed in the horizontal tube 12, and each of them is provided with a roller 18 at the end away from the shaft 25. The roller 18 is rolled and fitted into the arc-shaped slide rail 1202 provided on the inner wall of the horizontal tube 12.

[0071] The first assembly arm 26 and the second assembly arm 27 are respectively fixedly connected to a plurality of first grippers 29 and second grippers 30 by a connecting strip 28, and the plurality of first grippers 29 and the plurality of second grippers 30 are distributed alternately.

[0072] In this embodiment, with attachment Figure 7 Taking the state shown as an example, during normal operation, the first jaw 29 and the second jaw 30 are not fully engaged, but a channel is formed for the wire to pass through.

[0073] When the wire breaks, during the latter part of the swing of the horizontal tube 12, that is, when the guide wheel 24 slides in the straight through groove 2302, the limiting plate 2001 releases the limiting of the roller 21. When the second columnar spring 15 rebounds, causing the drive arm 17 to slide towards the inside of the horizontal tube 12, the drive arm 17 will apply pressure to the first assembly arm 26 and the second assembly arm 27. Since the shaft 25 will move closer to the center of the horizontal tube 12, the first assembly arm 26 and the second assembly arm 27 will swing synchronously but in different directions to adapt to the position change of the shaft 25. The rollers 18 on them will roll closer to each other in the arc-shaped slide rail 1202. Finally, the clamping range of the multiple first grippers 29 and the multiple second grippers 30 will be increased, so that the wire can be clamped by the multiple first grippers 29 and the multiple second grippers 30.

[0074] It should be noted that, since the first gripper 29 and the second gripper 30 are staggered, an axial force can be applied to the wire during clamping. Compared with the method of using clamping blocks to clamp the wire, this can effectively reduce the risk of slippage and make the reliability of effective clamping higher.

[0075] Furthermore, during the clamping process, the first assembly arm 26 and the second assembly arm 27 are offset towards each other, causing the first gripper 29 and the second gripper 30 to move synchronously and clamp the wire. Compared with two clamping blocks that move in opposite directions in a straight line, when the first gripper 29 and the second gripper 30 clamp, the channel formed by them for the wire to pass through gradually narrows, eventually clamping the wire. Therefore, the narrowing of the channel enables the wire to be positioned while achieving the wire clamping function, avoiding the problem of uneven clamping force caused by the height difference between different parts of the wire in the clamping components.

[0076] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0077] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
