Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal wire processing equipment, and in particular to a spring wire drawing machine with straightening function. Background Technology
[0002] In metal wire processing, in order to obtain wires with finer diameters, existing technologies generally adopt a continuous wire drawing process that combines a roller set with a multi-stage aperture tapering die. This process reduces the diameter of the metal wire by gradually reducing the die aperture and applying traction tension, and the formed wire exhibits a spiral bend.
[0003] However, even if the aforementioned bent metal wire is temporarily stored on a spool with a diameter larger than the bending diameter, when it is pulled out in subsequent processing (such as spring winding), the curvature of the wire is often much smaller than the diameter of the spool. As a result, the springs processed using the aforementioned metal wire cannot meet the expected performance indicators. Therefore, it is urgent to add a straightening process after metal wire processing and before winding to improve the straightness of the wire. Utility Model Content
[0004] The purpose of this invention is to provide a spring wire drawing machine with a straightening function. The straightening mechanism and the first straightening wheel straighten the metal wire after processing and before winding, thus solving the problem of the small bending diameter of the metal wire after multi-stage wire drawing.

[0010] As a preferred embodiment, the processing mechanism includes a first wire assembly, a first processing component, a second wire assembly, and a second processing component arranged in sequence, with the second processing component located near the straightening mechanism.
[0011] As a preferred embodiment, both the first and second processing components include a tool holder and a turret wheel. The tool holder is fixedly connected to the inner wall of the cold oil tank. The tool holder is provided with multiple processing molds with progressively smaller apertures. Multiple guide wheels are rotatably connected to the tool holder, with the guide wheels close to adjacent processing molds. The turret wheel is rotatably connected to the inner wall of the cold oil tank, and the diameter of multiple wheel pieces on the turret wheel increases progressively. A first drive assembly is provided on the machine base, and both turret wheels are connected to the first drive assembly.
[0012] As a preferred embodiment, the winding mechanism includes a third guide wheel and a lead screw assembly.

[0015] As a preferred embodiment, the machine base is provided with a tensioning mechanism, which is located near the first conductor assembly.
[0016] The beneficial effects of the spring wire drawing machine with straightening function disclosed in this utility model are:
[0017] After the external wire feeding mechanism delivers the metal wire to the processing mechanism, the processing mechanism sequentially completes the multi-stage wire drawing process and guides the metal wire through the straightening die. Since the elastic element limits the sleeve to the mounting seat, when the depth of the adjusting element touching the sleeve is adjusted, the sleeve rotates and shifts in the X and Y axes around the elastic element, thereby controlling the exit angle of the metal wire. When the metal wire passes around the first straightening wheel, the first straightening wheel is driven to rotate by the third motor. The first straightening wheel and the straightening die work together to straighten the metal wire, eliminating the problem of the wire bending diameter being too small. This significantly improves the straightness of the metal wire wound by the winding mechanism and avoids the problem of the finished product not meeting the expected performance indicators due to the mismatch of wire curvature during subsequent spring winding.

[0029] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:
[0030] Example 1, please refer to Figures 1-3 .
[0031] This utility model discloses a spring wire drawing machine with straightening function, including a machine base 1, a straightening mechanism 4 and a winding mechanism 5;
[0032] The machine base 1 is equipped with a tensioning mechanism 2, which includes a tensioning bracket 21 and a tensioning wheel 231. The tensioning bracket 21 is fixedly connected to the machine base 1, and a rocker arm 23 is rotatably connected to the tensioning bracket 21. A spring cylinder 22 is provided on the tensioning bracket 21. The output shaft of the spring cylinder 22 touches the middle of the rocker arm 23, and the tensioning wheel 231 is rotatably connected to the end of the rocker arm 23. The output shaft of the spring cylinder 22 pushes the rocker arm 23 to rotate and rise, so that the tensioning wheel 231 pulls the metal wire to maintain a suitable tension.
[0033] The machine tool 1 is equipped with a processing mechanism 3 and a cold oil tank 11. The processing mechanism 3 is placed inside the cold oil tank 11. The processing mechanism 3 includes a first wire assembly 31, a first processing component 32, a second wire assembly 35, and a second processing component 33. The first wire assembly 31, the first processing component 32, the second wire assembly 35, and the second processing component 33 are arranged sequentially inside the cold oil tank 11. In this embodiment, the cold oil tank 11 is preferably filled with cooling oil, which covers the first processing component 32 and the second processing component 33, so that the cooling oil can simultaneously achieve the dual functions of cooling and lubrication during the metal wire drawing process.
[0034] The tensioning mechanism 2 is located near the first guide wire assembly 31. The first guide wire assembly 31 includes a first mounting rod 311 and a first guide wheel 312. The first mounting rod 311 is fixedly connected to the machine base 1. A first slide block 511 is slidably connected to the first mounting rod 311. A first adjusting screw is rotatably connected to the first slide block 511. The first adjusting screw passes through the first slide block 511 and contacts the first mounting rod 311. The first guide wheel 312 is rotatably connected to the first slide block 511 of the first mounting rod 311. By adjusting the position of the first slide block 511 on the first mounting rod 311, the first guide wheel 312 can be aligned with one of the guide wheels 333 of the first processing assembly 32.
[0035] The metal wire introduced by the external wire feeding mechanism passes through the tension wheel 231 of the tensioning mechanism 2 and then around the first guide wheel 312 of the first guide assembly 31.
[0036] Please refer to Figure 1 and Figures 3-5 .
[0037] Both the first processing assembly 32 and the second processing assembly 33 include a tool holder 331 and a turret wheel 334. The tool holder 331 is fixedly connected to the cooling oil tank 11 of the machine base 1. Multiple machining dies 332 with progressively smaller diameters are fixedly connected to the tool holder 331. The machining die 332 with the largest diameter is located near the connection point between the tool holder 331 and the machine base 1. Multiple guide wheels 333 are rotatably connected to the tool holder 331, with the guide wheels 333 located near adjacent machining dies 332. The turret wheel 334 is rotatably connected to the cooling oil tank 11 of the machine base 1. The diameters of the multiple wheels on wheel 334 increase sequentially. The wheel with the smallest diameter on wheel 334 is located near the connection between wheel 334 and machine base 1. The processing mold 332 is located between wheel 334 and guide wheel 333. When the metal wire is drawn through the multi-stage tapered aperture processing mold 332, the metal wire will undergo elongation deformation. By configuring wheel 334 with wheels of different diameters, a speed gradient is formed, thereby dynamically adjusting the traveling speed of the metal wire and ensuring that the metal wire always maintains a suitable tension during the processing.
[0038] Furthermore, the machine tool 1 is equipped with a first drive assembly, and two pulleys 334 are respectively connected to the first drive assembly. The first drive assembly includes a first pulley 341, a second pulley, and a first motor. The two pulleys 334 extend from a first central shaft 321 and a second central shaft 335, respectively. The pulley 334 of the first processing assembly 32 is rotatably connected to the machine tool 1 through the first central shaft 321, which passes through the machine tool 1. The first pulley 341 is fixedly connected to the first central shaft 321, and the first pulley 341 is coaxial with the pulley 334 of the first processing assembly 32. The pulley 334 of the second processing assembly 33 is connected to the second central shaft 335. 5 is rotatably connected to machine base 1. The second central shaft 335 passes through machine base 1. The second pulley is fixedly connected to the second central shaft 335. The second pulley is coaxial with the tower wheel 334 of the second processing component 33. The first pulley 341 and the second pulley are fitted with a first transmission belt 342. The diameter of the first pulley 341 is larger than the diameter of the second pulley, so that the rotation speed of the tower wheel 334 of the second processing component 33 is greater than the rotation speed of the tower wheel 334 of the first processing component 32, ensuring that the metal wire always maintains a suitable tension during the processing. The first motor is placed inside machine base 1, and the output shaft of the first motor is connected to one of the tower wheels 334.
[0039] Furthermore, a third pulley 343 is fixedly connected to the second central shaft 335. The third pulley 343 is coaxial with the second pulley. A fourth pulley is fixedly connected to the output shaft of the first motor. A second transmission belt 344 is sleeved on the third pulley 343 and the fourth pulley. The output shaft of the first motor drives the pulley 334 of the second processing component 33 to rotate through the second transmission belt 344. The pulley 334 of the second processing component 33 drives the pulley 334 of the first processing component 32 to rotate through the first transmission belt 342.
[0040] The second guide assembly 35 includes a second mounting rod 351 and two second guide wheels 352. The second mounting rod 351 is fixedly connected to the machine base 1. Two second slide blocks 511 are slidably connected to the second mounting rod 351. A second adjusting screw is rotatably connected to the second slide block 511. The second adjusting screw passes through the second slide block 511 and touches the second mounting rod 351. The two second guide wheels 352 are rotatably connected to the two second slide blocks 511 on the second mounting rod 351, respectively. By adjusting the position of the second slide block 511 on the second mounting rod 351, one of the second guide wheels 352 can be aligned with the wheel piece with the largest diameter of the tower wheel 334 in the first processing assembly 32, and the other second guide wheel 352 can be aligned with the processing mold 332 with the smallest hole diameter in the second processing assembly 33.
[0041] The first guide wire assembly 31 guides the metal wire into the first processing assembly 32. The metal wire snakes around the first processing assembly 32, successively passing over each guide wheel 333 and each wheel piece on the tower wheel 334 in the first processing assembly 32. Driven by the tower wheel 334, the metal wire passes through multiple processing dies 332 with gradually decreasing apertures, gradually reducing the diameter of the metal wire. After passing over the largest diameter wheel piece on the tower wheel 334 in the first processing assembly 32, the metal wire enters the second guide wire assembly 35, passing around two second guide wire wheels 352 before entering the second... The processing component 33 and the second wire assembly 35 allow the metal wire to be guided into the processing mold 332 with the smallest aperture in the second processing component 33. The metal wire is serpentinely wrapped around the second processing component 33, passing through each guide wheel 333 and each wheel piece on the tower wheel 334 in the second processing component 33 in turn. Driven by the tower wheel 334, the metal wire passes through multiple processing molds 332 with gradually decreasing apertures in turn, further reducing the diameter of the metal wire. The metal wire that has completed two processing steps is then exported from the wheel piece with the largest diameter on the tower wheel 334 in the second processing component 33.
[0042] Please refer to Figure 1 and Figures 6-9 .
[0043] In this embodiment, there are preferably two straightening mechanisms 4, with the second processing component 33 located near one of the straightening mechanisms 4. The straightening mechanism 4 includes a mounting base 41 and a straightening mold 421.
[0044] Furthermore, the mounting base 41 is fixedly connected to the machine base 1. The mounting base 41 has a through mounting hole and a sealing ring. The sealing ring is coaxial with the mounting hole and touches the machine base 1. An elastic element 411 is fixedly connected inside the mounting hole. Multiple adjustable elements 412 are connected to the mounting base 41 at intervals. In this embodiment, the adjustable elements 412 are preferably bolts, and there are four of them. The four adjustable elements 412 are located in the four directions of the mounting base 41. The four adjustable elements 412 adjust the rotation offset of the sleeve 42 at the +X axis, -X axis, +Y axis, and -Y axis, respectively. The mounting base 41 has four threaded holes that communicate with the mounting hole. The adjustable elements 412 are connected to the threaded holes.
[0045] Furthermore, a sleeve 42 is fitted on the outer side of the straightening mold 421, and an elastic element 411 is fitted on the outer side of the sleeve 42. The elastic element 411 is fixedly connected to the sleeve 42. The adjusting element 412 touches the outer side of the sleeve 42. The adjusting element 412 is close to the end of the sleeve 42 and is located in the middle of the elastic element 411. When the adjusting element 412 rotates and deviates by one end angle, the adjusting element 412 rotates and stretches the elastic element 411 to deform, but the elastic element 411 can limit the adjusting element 412 in the mounting hole.
[0046] Furthermore, both the outer side of the straightening die 421 and the inner wall of the sleeve 42 are threaded. The thread of the straightening die 421 is connected to the thread of the sleeve 42. By rotating the straightening die 421, the position of the straightening die 421 in the sleeve 42 is adjusted, and the +Z axis displacement and -Z axis displacement of the straightening die 421 in the sleeve 42 are adjusted respectively.
[0047] Furthermore, the straightening mold 421 of one of the straightening mechanisms 4 is inserted into the cold oil tank 11, and the sealing ring can prevent the cooling oil in the cold oil tank 11 from overflowing from the gap of the mounting base 41. In this embodiment, it is preferred that the diameter of the straightening mold 421 of one of the straightening components is smaller than the diameter of the processing mold 332, and the diameter of the straightening mold 421 of the other straightening component is smaller than the diameter of the straightening mold 421 of one of the straightening components, so that the two straightening molds 421 perform the final two finishing processes while straightening the metal wire.
[0048] A third motor is provided on the machine base 1. The third motor is placed inside the machine base 1. The output shaft of the third motor passes through the machine base 1. The output shaft of the third motor is fixedly connected to the first straightening wheel 43. The first straightening wheel 43 is close to the straightening mold 421 of another straightening mechanism 4.
[0049] The machine 1 is provided with a second drive assembly, on which a second straightening wheel 44 is rotatably connected. The second straightening wheel 44 is located between two straightening mechanisms 4. A driven wheel 441 is rotatably connected to the second drive assembly, and the driven wheel 441 is close to the second straightening wheel 44.
[0050] Furthermore, a third central shaft and a fourth central shaft extend from the second straightening wheel 44 and the driven wheel 441, respectively. The second straightening wheel 44 is rotatably connected to the machine base 1 via the third central shaft, and the driven wheel 441 is rotatably connected to the machine base 1 via the fourth central shaft. Both the third and fourth central shafts pass through the machine base 1. The second drive assembly includes a fifth pulley, a sixth pulley, and a second motor. The fifth pulley is fixedly connected to the third central shaft of the tension wheel and is coaxial with the second straightening wheel 44. The sixth pulley is fixedly connected to the fourth central shaft of the driven wheel 441 and is coaxial with the driven wheel 441. A third transmission belt is fitted on the fifth and sixth pulleys. The second motor is placed inside the machine base 1, and the output shaft of the second motor is fixedly connected to the third central shaft of the second straightening wheel 44. The output shaft of the second motor drives the second straightening wheel 44 to rotate, and the third transmission belt drives the driven wheel 441 to rotate.
[0051] The metal wire introduced by the second processing component 33 passes through the straightening mold 421 of one of the straightening components and then around the second straightening wheel 44. The second straightening wheel 44 and the straightening mold 421 of one of the straightening components work together to perform the first straightening of the metal wire, and at the same time, perform the first fine processing on the diameter of the metal wire. After the metal wire passes through the second straightening wheel 44 and then around the driven wheel 441, it passes through the second straightening wheel 44 again. The horizontal plane of the driven wheel 441 is higher than the horizontal plane of the straightening mold 421 of one of the straightening components to avoid the metal wires rubbing against each other on the second straightening wheel 44. The metal wire introduced by the second straightening wheel 44 passes through the straightening mold 421 of another straightening component and then around the first straightening wheel 43. The first straightening wheel 43 and the straightening mold 421 of another straightening component work together to perform the second straightening of the metal wire, and at the same time, perform the second fine processing on the diameter of the metal wire.
[0052] The winding mechanism 5 is located near the first straightening wheel 43; the metal wire after secondary straightening is guided into the winding mechanism 5 through the first straightening wheel 43.
[0053] Example 2, please refer to Figure 1 and Figure 8 .
[0054] Based on the original embodiment 1, the winding mechanism 5 includes a lead screw device 51 and a third guide wheel 52; the lead screw device 51 is placed on the worktable, a slide block 511 is slidably connected to the lead screw device 51, a winding motor 512 is fixedly connected to the slide block 511, the output shaft of the winding motor 512 is parallel to the traveling direction of the slide block 511, and an I-beam wheel 513 is detachably connected to the output shaft of the winding motor 512; a mounting bracket is rotatably connected to the third guide wheel 52, the mounting bracket is fixedly connected to the machine base 1, the third guide wheel 52 is rotatably connected to the machine base 1 through the mounting bracket, and the third guide wheel 52 is located between the first straightening wheel 43 and the I-beam wheel 513;
[0055] After secondary straightening, the metal wire is wound into the I-beam spool 513 via the third guide wheel 52. The winding motor 512 drives the I-beam spool 513 to rotate synchronously, increasing the tension of the wound metal wire. The lead screw device 51 drives the slide block 511 to slide back and forth, achieving a high-density arrangement of the wire on the outside of the I-beam spool 513. When the I-beam spool 513 is fully loaded, the fully loaded I-beam spool 513 is removed and replaced with an unloaded I-beam spool 513 for the next winding operation. By using the I-beam spool 513 with a standard diameter for winding, the straightened metal wire is wound onto the I-beam spool 513. During subsequent processing, since the curvature diameter of the metal wire pulled out from the I-beam spool 513 is larger than the diameter of the I-beam spool 513, the expected performance indicators of the finished spring can be avoided due to the bending diameter of the metal wire being too small.
[0056] Example 3, please refer to Figure 1 and Figures 9-11 .
[0057] Based on the original embodiment 1, the winding mechanism 5 includes a winding wheel 53 and two fourth guide wheels 54. The winding wheel 53 is fixedly connected to the top of the first straightening wheel 43. The winding wheel 53 and the first straightening wheel 43 are coaxial. The diameter of the winding wheel 53 is equal to the diameter of the first straightening wheel 43. A protrusion extends from the outer side of the winding wheel 53. The protrusion surrounds the outer side of the winding wheel 53 and is located between the winding wheel 53 and the first straightening wheel 43. The protrusion can prevent the metal wire wound on the winding wheel 53 from slipping into the first straightening wheel 43. The fourth guide wheels 54 are rotatably connected to the machine base 1 and are located outside the winding wheel 53.
[0058] Furthermore, multiple limiting rods 531 extend from the top of the take-up reel. In this embodiment, it is preferable that there are four limiting rods 531, which are parallel to each other and close to the edge of the take-up reel. A conical surface is provided on the outer side of the take-up reel, and the angle of the conical surface is marked as α in the accompanying drawings. In this embodiment, it is preferable that the angle of α is 5°, so that the diameter of the bottom of the take-up reel is larger than the diameter of the top of the take-up reel.
[0059] After secondary straightening, the metal wire is guided away from the first straightening wheel 43 by two fourth guide rollers 54, allowing the metal wire to be wound around the protrusion and into the take-up wheel 53. The first straightening wheel 43 and the take-up wheel 53 rotate synchronously, increasing the tension of the take-up wheel 53 in winding the metal wire. By using a take-up wheel 53 with a standard diameter to wind the metal wire, the straightened metal wire is wound onto the take-up wheel 53. During subsequent processing, since the curvature diameter of the metal wire is larger than the diameter of the take-up wheel 53, the expected performance indicators of the finished spring can be effectively avoided due to the small bending diameter of the metal wire. Based on the outer conical surface structure of the take-up wheel, the metal wire generates an adaptive axial displacement as the coil diameter increases during winding. This gradually expanding spatial distribution characteristic achieves the axial dimension expansion of the coil, ensuring winding density and providing operators with convenient space for coil disassembly.
[0060] This utility model provides a spring wire drawing machine with a straightening function. After the external wire feeding mechanism delivers the metal wire to the processing mechanism, the processing mechanism sequentially completes a multi-stage wire drawing process and guides the metal wire through the straightening die. Since the elastic element limits the sleeve to the mounting seat, when the depth of the adjusting element touching the sleeve is adjusted, the sleeve rotates and shifts in the X and Y axes around the elastic element, thereby controlling the exit angle of the metal wire. When the metal wire passes around the first straightening wheel, the first straightening wheel is driven to rotate by the third motor. The first straightening wheel and the straightening die work together to straighten the metal wire, eliminating the problem of the wire bending diameter being too small, significantly improving the straightness of the metal wire wound by the winding mechanism, and avoiding the problem of the finished product not meeting the expected performance indicators due to the mismatch of wire curvature during subsequent spring winding.
[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
