Description

Technical Field

[0001] This invention belongs to the field of wire drawing machine technology, and in particular relates to an inverted wire drawing machine that prevents mold damage. Background Technology

[0002] The inverted wire drawing machine is the core equipment for metal wire drawing. It is mostly used for diameter reduction drawing of soft metal wires such as copper wire. During its operation, the wire winding equipment needs to be moved to the bottom of the wire drawing disc to ensure that the wire winding equipment and the wire drawing disc maintain a high degree of coaxiality, so as to achieve stable vertical winding of the wire.

[0003] Existing inverted wire drawing machines generally adopt a motor-driven traveling wheel-track transfer structure, relying on motor encoder pulse counting to achieve the positioning and stopping of the wire winding equipment. However, there are inevitably machining tolerances and assembly gaps between the traveling wheel and the track. After long-term operation, the traveling wheel wears down, and copper shavings, iron shavings, oil stains and other impurities easily adhere to the track surface, all of which can cause the wire winding trolley's travel trajectory to deviate, thereby reducing the repeatability and positioning accuracy of the equipment.

[0004] When the rotation center of the wire winding equipment deviates from the coaxiality of the wire drawing disc, the downward-drawn copper wire will experience continuous lateral sway. This eccentric pull on the drawing die's orifice causes unilateral friction and pressure, exacerbating die wear and even leading to breakage. Simultaneously, the wire is continuously subjected to lateral forces, resulting in scratches on the copper wire surface, substandard roundness of the finished wire, and disordered wire arrangement during the winding stage, leading to quality problems such as tangled and overlapping wires. Therefore, this invention provides an inverted wire drawing machine that prevents die damage, thereby solving the above problems. Summary of the Invention

[0035] 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.

[0036] Example 1, please refer to Figures 1 to 12 The present invention is an inverted wire drawing machine for preventing mold damage, including a wire drawing disc 1, a bearing component 2 rotatably disposed directly below the wire drawing disc 1, and an upper winding rod 3 disposed around the concentric linkage part fixed at the bottom of the wire drawing disc 1; an elastic reset component 4 is disposed at the center of the bearing component 2, the entire elastic reset component 4 is made of lightweight material, the elastic reset component 4 includes a lifting plate 5 disposed below the bearing component 2, and connecting seats 6 are symmetrically fixed at the bottom of the lifting plate 5.

[0037] The lifting plate 5 is provided with a lower winding rod 7 that moves up and down synchronously with it. The lower winding rod 7 is arranged vertically and slides through the bearing assembly 2. The lower winding rod 7 is sleeved on the outside of the corresponding upper winding rod 3. The lifting plate 5 is provided with limiting wheel sets 8 on opposite sides that are detachably connected to the connecting seat 6. The lifting plate 5 is provided with a magnetic supply assembly 9 symmetrically below it. The magnetic supply assembly 9 includes a horizontal magnetic supply plate 10 with a lower magnet. Above the horizontal magnetic supply plate 10 is a magnetic locking part 11 for moving upward and inserting into the bearing assembly 2. The magnetic locking part 11 includes an upper magnet 12 that is magnetically repelled by the lower magnet. The lifting plate 5 is provided with a support assembly 13 coaxial with it below it. The support assembly 13 includes a support cylinder 14. The limiting wheel sets 8 are used to roll along the top surface of the support cylinder 14.

[0038] like Figure 8and Figure 9 As shown, the inverted wire drawing machine also includes a wire drawing frame 15, a wire drawing disc 1 is located on the inner side of the wire drawing frame 15 near the top, a first motor 16 connected to the wire drawing disc 1 is installed on the top of the wire drawing frame 15, and a support ring 17 and a support disc 18 are fixed on the inner side of the wire drawing frame 15, with the support ring 17 located between the support disc 18 and the wire drawing disc 1.

[0039] The specific structure of the bearing component 2 in this invention is as follows: Figure 10 As shown, the bearing assembly 2 includes a bearing disk 19 rotatably disposed inside the support ring 17. The top of the bearing disk 19 is provided with radial channels 20 arranged in a circumferential array. The top of the bearing disk 19 is fixed with support rails 21 located on both sides of the radial channels 20. Locking holes 22 offset from the center of the bearing disk 19 are provided between the support rails 21.

[0040] like Figure 9 As shown, the concentric linkage unit includes a linkage plate 23 located below the wire drawing plate 1. The linkage plate 23 is connected to the wire drawing plate 1 by a fixing plate. The fixing plate has vertically arranged limiting channels on its periphery. The linkage plate 23 has upper radial cavities on its periphery. The top of the linkage plate 23 has a limiting groove that communicates with the upper radial cavities.

[0041] In this embodiment of the invention, as Figure 3 and Figure 4 As shown, the elastic reset assembly 4 also includes a connecting plate 24 disposed above the bearing assembly 2. A lower reinforcing column 25, which slides through the bearing plate 19, is fixed to the top of the lifting plate 5. A limiting element is fixed to the inner wall of the central hole of the lifting plate 5. A vertical sliding groove that cooperates with the limiting element is opened on the circumferential side of the lower reinforcing column 25. Through this structural design, when the lower reinforcing column 25 is driven to rotate, the bearing plate 19 can be driven to rotate synchronously. The connecting plate 24 is fixed to the circumferential side of the lower reinforcing column 25. A connecting rod that slides through the bearing plate 19 is fixed between the connecting plate 24 and the lifting plate 5. This connecting rod is a reinforcing rod used to improve the stability of the synchronous rotation of the elastic reset assembly 4 and the bearing plate 19. An elastic element is provided between the connecting plate 24 and the bearing plate 19. This elastic element can be a reset spring that supports the connecting plate 24. A downward radial cavity is provided circumferentially on the circumferential side of the lifting plate 5.

[0042] The specific structure of the limiting wheel assembly 8 in this invention is as follows: Figure 3 and Figure 5 As shown, the limiting wheel assembly 8 includes a support rod 26 that is threadedly connected to the connecting seat 6. A limiting wheel 27 is installed at the end of the support rod 26. When the limiting wheel 27 rolls along the top surface of the support cylinder 14, the support rod 26 is always in a threaded tightened state with the connecting seat 6.

[0043] The magnetic locking part 11 also includes a vertical locking rod 28. The top of the vertical locking rod 28 is provided with a chamfered guide structure, and the bottom of the locking hole 22 is also provided with a chamfered guide structure to ensure that the vertical locking rod 28 can be smoothly inserted into the locking hole 22. The vertical locking rod 28 is slidably mounted on the support plate inside the wire drawing machine frame 15. A limiting ring 29 that fits against the top of the support plate is fixed on the vertical locking rod 28. The upper magnet 12 is installed at the lower end of the vertical locking rod 28. In the initial state, the limiting ring 29 is supported by the support plate. At this time, the upper magnet 12 is close to the top of the horizontal magnetic supply plate 10.

[0044] Example 2, based on Example 1, such as Figure 3 and Figure 11 As shown, a movable seat 30 is slidably provided inside the radial channel 20. A guide hole 31 is provided at the top of the movable seat 30, and a guide member is fixed on the inner wall of the guide hole 31. The lower winding rod 7 is slidably fitted inside the guide hole 31. The lower winding rod 7 has a vertical groove on its circumferential side that cooperates with the guide member. Through this structural design, the lower winding rod 7 passing through the movable seat 30 can be prevented from deflecting. A radial support plate 32 inserted into the lower radial cavity is fixed on the circumferential side of the lower winding rod 7. A first guide ball 33 is installed at the lower end of the lower winding rod 7. The surface of the first guide ball 33 is treated with a smooth mirror surface to reduce the frictional resistance during the movement of the first guide ball 33. The lower end of the upper winding rod 3 is inserted into the axial cavity at the top of the lower winding rod 7. A guide slope is provided at the upper end of the lower winding rod 7. Through this guide slope design, the copper wire can fall smoothly down the surface of the upper winding rod 3 onto the lower winding rod 7. During the copper wire drawing process, the lower winding rod 7 always maintains a coaxial state with the upper winding rod 3.

[0045] like Figure 3 and Figure 4 As shown, the inverted wire drawing machine also includes a heavy-pressure positioning component 34; wherein, the heavy-pressure positioning component 34 includes a heavy-pressure plate 35 located above the linkage plate 23 and slidably fitted between the limiting channels. The bottom of the heavy-pressure plate 35 is provided with multiple sets of positioning grooves 36 arranged in a circumferential array. Each set of positioning grooves 36 is arranged radially along the heavy-pressure plate 35. The bottom of the heavy-pressure plate 35 is fixed with an upper reinforcing column 37 that is magnetically fixed to the lower reinforcing column 25. It should be noted that linkage magnets are provided at the top of the lower reinforcing column 25 and the bottom of the upper reinforcing column 37. When the lower reinforcing column 25 is concentrically attached to the upper reinforcing column 37, the lower reinforcing column 25 and the upper reinforcing column 37 are in a magnetically attracted state. At the same time, a rectangular piece is fixed at the center of the top of the lower reinforcing column 25. The bottom of the upper reinforcing column 37 is provided with a rectangular groove that is inserted and fitted with the rectangular piece. When the rectangular piece is inserted and fitted with the rectangular groove, when the heavy-pressure plate 35 is driven to rotate, the upper reinforcing column 37 can drive the lower reinforcing column 25 and the lifting plate 5 to rotate synchronously.

[0046] The upper winding rod 3 has an L-shaped structure and is inserted into the upper radial cavity. A slider is fixed to the top of the upper winding rod 3, slidingly fitted within the limiting groove. A second guide ball 38, adapted to the positioning groove 36, is fixed to the top of the slider. It should be noted that the lifting distance of the pressure plate 35 is small; it only requires disengaging the positioning groove 36 from the second guide ball 38. This lifting process will not cause the upper reinforcing column 37 to disengage from the lower reinforcing column 25. To facilitate the application of force by an external lifting tool, a lifting ring (not shown in the figure) is fixed to the edge of the pressure plate 35. The lifting action of the pressure plate 35 can be achieved by using an external tool in conjunction with the lifting ring. This structural design prevents the upper winding rod 3 from deflecting when it slides along the upper radial cavity. Simultaneously, the bottom of the upper winding rod 3 has a chamfered structure to ensure that the bottom of the upper winding rod 3 can smoothly slide into the axial cavity at the top of the lower winding rod 7. The second guide ball 38 has a smooth mirror finish to reduce frictional resistance during its movement.

[0047] like Figure 8 and Figure 9 As shown, the output end of the second motor 39 installed at the bottom of the support plate 18 is connected to the drive shaft. The bottom of the support cylinder 14 is fixed with a guide tube sleeved on the drive shaft. The linkage protrusion fixed on the inner wall of the guide tube slides into the linkage groove on the drive shaft. With this structural design, when the drive shaft is rotated by the second motor 39, the synchronous rotation of the support cylinder 14 can be achieved. At the same time, the guide tube at the bottom of the support cylinder 14 can move up and down along the drive shaft.

[0048] The magnetic supply assembly 9 also includes a cylinder 40 mounted on the wire drawing frame 15. The movable end of the cylinder 40 is connected to a triangular extrusion seat 41. A guide roller 42 is mounted on the inclined surface of the triangular extrusion seat 41 via a rotating shaft. The horizontal magnetic supply plate 10 is connected to the triangular extrusion seat 41 via a fixed rod.

[0049] Furthermore, such as Figure 3 and Figure 12As shown, the bottom edge of the support cylinder 14 is designed as a curved surface structure that slides with the guide roller 42. The inner wall of the support cylinder 14 is circumferentially arrayed with spiral plates 43 corresponding to the lower winding rod 7. The diameter of the lifting plate 5 is smaller than the distance between the inner walls of the circumferentially arranged spiral plates 43. The surface of the spiral plates 43 is treated with a smooth mirror finish and coated with lubricant. The top of the spiral plates 43 is a planar structure. Multiple spiral channels 44 are provided on the surface of the spiral plates 43 from the inside out. The top of the spiral plates 43 is provided with a ball guide inlet 45 corresponding to the spiral channel 44. The ball guide inlet 45 communicates with the corresponding spiral channel 44. It should be noted that the diameter of the ball guide inlet 45 is larger than the diameter of the first guide ball 33, and the ball guide inlet 45... The intersection with the spiral channel 44 is a curved chamfered structure. When the first guide ball 33 passes through the guide ball inlet 45 and enters below the guide ball inlet 45 (the radial support plate 32 is still above the support cylinder 14), the lower winding rod 7 can be driven to slide into the spiral channel 44 along the curved chamfered structure by rotating the support cylinder 14. During the process of controlling the rotation of the support cylinder 14 at a set angle, the radial support plate 32 is always above the upper surface of the spiral plate 43, so that the spiral plate 43 will not interfere with the movement of the descending radial support plate 32. That is, during the downward movement of the radial support plate 32, the radial support plate 32 is always higher than the upper surface of the spiral plate 43 (or does not physically collide with the spiral plate 43).

[0050] like Figure 1As shown, initially, the support cylinder 14 is in its lowest position, and the magnetic supply components 9 on both sides are in their initial positions. The support cylinder 14 is supported by the guide rollers 42 on both sides. The horizontal magnetic supply plate 10 and the upper magnet 12 are horizontally misaligned. The limiting wheel 27 is attached to the top surface of the support cylinder 14. The lower reinforcing column 25 and the upper reinforcing column 37 are concentrically attached and magnetically attracted to each other. At the same time, the rectangular groove at the bottom of the upper reinforcing column 37 is inserted into the rectangular piece at the top of the lower reinforcing column 25. The bottom of the upper winding rod 3 is inserted into the axial cavity at the top of the lower winding rod 7. The positioning groove 36 (spherical groove) on the positioning component 34 is inserted and engaged with the second guide ball 38. At this time, the wire drawing disc 1, the elastic reset component 4 and the heavy pressure positioning component 34 are in a coaxial state, and the upper winding rod 3 and the lower winding rod 7 are also in a coaxial state. Through the above concentric structure arrangement, the copper wire in the wire drawing process can be effectively prevented from being wound off on the lower winding rod 7, so that the copper wire drawn downward will not produce continuous lateral swing, and will not cause unilateral friction and extrusion on the mold, and will not aggravate the wear of the wire drawing mold or even breakage, thereby ensuring the winding quality of the wire drawing copper wire. During the wire drawing process, when the first motor 16 drives the wire drawing disc 1 to rotate according to the set program, the heavy pressure positioning component 34, which rotates synchronously with the wire drawing disc 1, drives the upper winding rod 3 and the elastic reset component 4 to rotate synchronously. The limit wheel 27, which rotates synchronously with the elastic reset component 4, rolls along the top surface of the support cylinder 14. When the elastic reset component 4 rotates, it drives the bearing disc 19 and each lower winding rod 7 to rotate synchronously. In this way, the copper wire can be wound and wound on each lower winding rod 7 arranged in a ring. The wound copper wire is supported by the support rail 21. After the copper wire winding process is completed, the copper wire is cut. At this time, the whole device is in the initial state, and the locking hole 22 is located directly above the vertical locking rod 28 and remains coaxial.

[0051] Subsequently, each limit wheel group 8 is removed from the connecting seat 6. At this time, the entire elastic reset assembly 4 is supported by the elastic element and held in its original position. Then, the cylinders 40 on both sides are started simultaneously to control the triangular pressing seat 41 to move closer to each other to the set position. The guide rollers 42 on both sides press the curved structure at the bottom of the support cylinder 14, so that the support cylinder 14 moves up to the set position. At this time, the horizontal magnetic plate 10 moves to the lower part of the corresponding upper magnet 12. The first guide ball 33 passes through the guide ball inlet 45 and enters the lower part of the guide ball inlet 45. The upper magnet 12 is driven by the magnetic repulsion force of the horizontal magnetic plate 10 to move the vertical locking rod 28 up and insert it into the corresponding locking hole 22. In this way, the position of the bearing plate 19 is locked by the vertical locking rods 28 on both sides. Subsequently, the second motor 39 controls the support cylinder 14 to rotate at a set angle, causing the lower winding rod 7 to slide into the spiral channel 44 along the curved chamfered structure. After the first guide ball 33 adheres to the lower surface of the spiral plate 43, the lower surface of the spiral plate 43 pushes the first guide ball 33 downward, causing each lower winding rod 7 to move down synchronously and compress each elastic element until the lower reinforcing column 25 disengages from the upper reinforcing column 37 to the set position. At this time, each lower winding rod 7 is completely separated from the upper winding rod 3 and is in a low position, so that the copper wire coil can be removed from the outside of each lower winding rod 7. The above-mentioned in-situ wire drawing and winding operation method allows for the removal of the copper wire coil without removing the winding equipment (i.e., the integrated structure consisting of the lower winding rod 7, the bearing component 2, and the elastic reset component 4) from under the wire drawing disc after the copper wire winding operation is completed. This avoids the problem of deviation from the axis of the wire drawing disc caused by the horizontal movement of the winding equipment. At the same time, the material handling method of each lower winding rod 7 descending in place shortens the stroke for lifting and handling the copper wire coil, thereby improving the working efficiency of copper wire drawing processing.

[0052] After the copper wire coil is removed, the second motor 39 controls the support cylinder 14 to reverse the same angle to complete the reset. Under the elastic restoring force of the elastic element, the first guide ball 33 gradually slides upward along the lower surface of the spiral plate 43 back to the guide ball inlet 45. At this time, the lower reinforcing column 25 and the upper reinforcing column 37 are concentrically attached again, and the lower reinforcing column 25 and the upper reinforcing column 37 are magnetically attracted again. At the same time, the rectangular groove at the bottom of the upper reinforcing column 37 and the rectangular piece at the top of the lower reinforcing column 25 are inserted and engaged again, and the lower winding rod 7 and the upper winding rod 3 are reconnected. Then, the cylinders 40 on both sides are started synchronously to control the triangular extrusion seat 41 to move in the opposite direction to complete the reset. At this time, the support cylinder 14 moves downward back to the initial position, and the first guide ball 33 returns to the starting position. Figure 2At the position above the support cylinder 14 shown, the horizontal magnetic plate 10 is once again horizontally misaligned with the corresponding upper magnet 12. The magnetic force on the upper magnet 12 disappears, and the vertical locking rod 28 moves downward under its own gravity to complete the reset and release the position lock on the bearing plate 19. After reinstalling each limit wheel group 8 onto the connecting seat 6 and making it fit against the top surface of the support cylinder 14, the copper wire drawing process can be performed again.

[0053] When drawing different types of copper wire coils, it is necessary to adjust the circumferential spacing of each upper winding rod 3 and lower winding rod 7. The specific adjustment process is as follows:

[0054] First, lift the heavy-pressure positioning component 34 upwards. Under the action of magnetic attraction, the lower winding rod 7 is simultaneously lifted by the elastic reset component 4 until the positioning groove 36 at the bottom of the heavy-pressure plate 35 disengages from the second guide ball 38 at the top of the upper winding rod 3. Then, move each upper winding rod 3 outwards, causing the corresponding lower winding rod 7 to move outwards synchronously, so that the second guide ball 38 at the top of the upper winding rod 3 aligns with the positioning groove 36 at the designated position. At this time, the first guide ball 33 is simultaneously aligned with the corresponding guide ball insertion inlet 45. Then, gradually lower the heavy-pressure positioning component. 34. Under the action of magnetic attraction, the lower winding rod 7 is synchronously lowered by the elastic reset component 4 until the positioning groove 36 at the bottom of the heavy pressure plate 35 re-engages with the second guide ball 38 at the top of the corresponding upper winding rod 3. The positioning groove 36 locks the position of each upper winding rod 3 and lower winding rod 7, so that the upper winding rod 3 and lower winding rod 7 cannot move radially. In this way, the circumferential spacing of each upper winding rod 3 and lower winding rod 7 is adjusted to meet the wire drawing process of copper wire coils of different diameters.
