Description

Technical Field

[0001] This invention relates to the field of alloy wire drawing technology, and more specifically, to an alloy wire drawing device and its drawing process. Background Technology

[0002] Alloy wire drawing is a plastic processing technology that uses external force to force an alloy billet through a die with a specific aperture, causing the billet to undergo plastic deformation and ultimately produce a fine wire product. It is one of the core technologies for preparing high-precision alloy wires.

[0003] When using the existing wire drawing equipment, the operator first passes the alloy wire through the drawing die, then winds it around the outer wall of the roller, and then installs the drawing die onto the drawing die base; by rotating the roller, the drawing process of the alloy wire can be completed.

[0004] In conventional scenarios, some pulleys have a conical structure. To ensure that the alloy wire can be drawn horizontally, the drawing die base is machined to match the tilt angle of the pulley. However, this method of machining the drawing die base according to the shape of the pulley will significantly increase the production cost of the drawing die base. To address this issue, the staff has made improvements and optimizations to the existing system. The horizontal die base can swing within the drawing device, thereby adjusting the tilt angle of the horizontal die base. This eliminates the need for contour machining and enables horizontal drawing of the alloy wire, effectively avoiding the high cost problem.

[0005] However, the horizontal die holder tilting scheme still has the following problems: some of the pulleys are non-uniform stepped structures, that is, not conventional conical structures. Their diameter decreases at different rates, and the conical cross-section is curved. This special structure means that even if the angle of the horizontal die holder is adjusted, the wire drawing die cannot be matched with the pulley groove position, which leads to the situation where the horizontal die holder tilting method is not applicable. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an alloy wire drawing device and its drawing process.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an alloy wire drawing device, comprising a main body assembly, a wire guide assembly installed on one side of the main body assembly, and a winding assembly disposed on the other side of the main body assembly.

[0014] The present invention is further configured such that: each of the two sets of tower wheel assemblies includes a rotating shaft rotatably connected to the inside of the housing, and a tower wheel body is mounted on the outer side wall of each of the two rotating shafts.

[0015] The present invention is further configured such that: the mold base assembly further includes two sets of locking mechanisms symmetrically installed on the side wall of the I-beam frame, the square support rod is located between the two sets of locking mechanisms, and a locking bolt is threadedly connected between the I-beam frame and the inner wall of the box body.

[0016] The present invention is further configured such that: both sets of locking mechanisms include an L-shaped plate, the side wall of the L-shaped plate is provided with a sliding groove, a double-acting screw is rotatably connected to the side of the sliding groove away from the square support rod, two clamping plates are threaded to the outer side wall of the double-acting screw, the two clamping plates pass through the interior of the corresponding sliding groove, a slot is installed on the side wall of the I-beam frame, and one side of the L-shaped plate passes through the interior of the slot.

[0017] The present invention is further configured such that: the module mechanism also includes a guide mechanism installed on one side of the connecting block, and two limiting grooves are opened on the side of the connecting block away from the guide mechanism, and the guide mechanism is inserted into the two limiting grooves.

[0019] The present invention is further configured such that: two placement slots are provided on the top of the connecting block, the wire drawing die is placed inside one of the placement slots on the top of the corresponding connecting block, wire grooves are provided on the side wall of the connecting block and the side wall of the placement slot, and chamfers are provided inside the wire grooves, and two top pillars are symmetrically connected to the bottom of the connecting block.

[0020] An alloy wire drawing process, using an alloy wire drawing device as described above, includes the following steps: S1. Place the mold base assembly on top of the tower wheel assembly, and guide and adjust the mold base assembly by conforming to the shape of the tower wheel assembly so that the shape of the mold base assembly matches that of the tower wheel assembly.

[0021] S2. Install the die holder assembly between the two roller assemblies, and then wind the alloy wire through the guide wire assembly, die holder assembly and two sets of roller assemblies.

[0022] S3. After the alloy wire is wound, it is wound up using a winding assembly.

[0023] In summary, this application includes at least one of the following beneficial technical effects: (1) Through the cooperation of multiple individually adjustable connecting blocks and top columns, the mold base assembly can adjust the splicing misalignment height according to the shape of the tower wheel. That is, the height of the connecting block can be positioned by inserting the top column into the tower wheel groove. There is no need to process special mold bases for special tower wheels or repeatedly adjust the tilt angle of the horizontal mold base. This solves the problem that the traditional swing tilting method cannot be adapted to non-equal step special tower wheels and improves the functionality of the device.

[0024] (2) The number of connecting blocks can be freely spliced ​​according to the length of the tower wheel body and the number of tower wheel grooves to meet the usage requirements of tower wheels of different lengths. The locking mechanism has the function of first guiding and then locking, which facilitates the positioning of the connecting blocks during the adjustment stage. Furthermore, after the connecting blocks are adjusted to the correct position, the locking mechanism can drive the clamping plate through the bidirectional screw to clamp the connecting blocks, so that multiple connecting blocks form a whole and ensure the stability of the pulling operation.

[0025] (3) By opening the chamfer in the groove of the connecting block sidewall, the alloy wire passing through can be guided to ensure that the alloy wire returns to the relative position with the die hole of the drawing die before entering the drawing die, reducing the degree of left and right skew. The height of the connecting block can be adjusted according to the shape of the roller groove, so that the die hole of the drawing die and the roller groove are matched in height, reducing the risk of uneven wear when the alloy wire enters the die hole from the root and extending the service life of the drawing die.

[0026] (4) Through the sliding fit between the connecting plate and the limiting groove in the guide mechanism, and the matching insertion between the guide column and the guide groove, an adjustable splicing base is provided for the connecting block. The connecting plate can be pulled out or pushed in the limiting groove to compensate for the spacing of different tower wheel grooves, so that the connecting block can realize the vertical misalignment and spacing adjustment during splicing. It adapts to the tower wheel groove width and spacing differences of different tower wheel bodies, ensuring the stability and applicability of alloy wire winding. Attached Figure Description

[0041] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0043] Please see Figures 1-13 The present invention provides the following technical solutions: Example 1, see Figures 1-4An alloy wire drawing device includes a main component 1, which includes a frame 11 and a housing 12 mounted on top of the frame 11. A cover 13 is hinged to the top of the housing 12. The housing 12 provides space for alloy wire drawing. In order to avoid wear of the equipment and thermal brittleness of the alloy wire during drawing, drawing oil needs to be sprayed at the alloy wire drawing position to achieve lubrication and cooling. The housing 12 can also carry and collect the used drawing oil. In addition, the cover 13 seals the housing 12 to prevent the drawing oil from splashing to the outside.

[0044] See Figures 1-3 A wire guide assembly 2 is installed on one side of the main component 1. The wire guide assembly 2 is used to guide the alloy wire before drawing. The specific structure of the wire guide assembly 2 is as follows: See Figures 1-3 and Figure 12 The wire guide assembly 2 includes a wire feeding tube 21 installed on one side of the frame 11. Two wire guide plates 22 are vertically installed downward at the end of the wire feeding tube 21. Two wire guide rods 23 are connected between the two wire guide plates 22. A ceramic eye 24 is installed on the outer side wall of the wire feeding tube 21. A wheel frame 25 is installed on the side wall of the frame 11. An auxiliary guide wheel 26 is rotatably connected to the wheel frame 25. An inlet mold 27 is installed in communication with the side wall of the frame 11. The inlet mold 27 is configured to cooperate with the auxiliary guide wheel 26, the ceramic eye 24 and the wire guide rods 23.

[0045] The coil with the alloy wire is placed below the wire guide assembly 2. Then the alloy wire is released and wound around the outer wall of the two wire guide rods 23 in sequence. It then passes through the inside of the ceramic eye 24, the auxiliary guide wheel 26 and the inlet mold 27 to reach the inside of the housing 12. After the alloy wire is released into the inside of the housing 12, it is pulled out.

[0046] See Figures 1-4 A winding assembly 3 is installed on the side of the frame 11 away from the wire guide assembly 2. The winding assembly 3 is used to wind up the drawn alloy wire. The specific structure of the winding assembly 3 is as follows: See Figure 4 and Figure 13The take-up assembly 3 includes a take-up box 31 and a constant speed wheel 33 and a wire separating wheel 34 rotatably connected inside the take-up box 31. A swing plate 35 is rotatably connected inside the take-up box 31, and a swing guide wheel 36 is rotatably connected to the end of the swing plate 35. A take-up reel 37 is rotatably connected to the lower side wall of the take-up box 31. The take-up box 31 is fitted to the box body 12, and an exit mold 32 is installed on the mating surface between the take-up box 31 and the box body 12. The exit mold 32 is height-matched to the constant speed wheel 33. A wire guide wheel is installed inside the take-up box 31 and above the constant speed wheel 33. Alloy... The wire enters the inside of the take-up box 31 through the exit mold 32, passes above the constant speed wheel 33 and the bottom of the wire separating wheel 34, and then turns around the outer wall of the constant speed wheel 33 to reach the wire guide wheel. After that, the alloy wire passes the outer wall of the swing guide wheel 36 and is wound up by the take-up reel 37. The take-up box 31 is also equipped with a take-up drive mechanism, which can be a take-up drive motor. The output end of the take-up drive motor is connected to the take-up reel 37. The take-up drive motor drives the take-up reel 37 to rotate, thereby winding up the conveyed alloy wire.

[0047] See Figure 3 and Figure 4 The housing 12 has two roller assemblies 4 inside. The two roller assemblies 4 are used to guide the alloy wire during the drawing process and provide continuous and stable traction force. The specific structure of the roller assembly 4 is as follows: See Figure 4 and Figure 5 Both sets of tower wheel assemblies 4 include a rotating shaft 41 rotatably connected inside the housing 12. A tower wheel body 42 is installed on the outer wall of each of the two rotating shafts 41. The tower wheel body 42 can be replaced as needed. The tower wheel body 42 is sleeved on the outer wall of the corresponding rotating shaft 41. Two tower wheel drive mechanisms are installed inside the frame 11. The tower wheel drive mechanism can be a tower wheel drive motor, which is not specifically limited here. The output end of the tower wheel drive motor is connected to the corresponding rotating shaft 41. The tower wheel drive motor drives the rotating shaft 41 to rotate, thereby driving the corresponding tower wheel body 42 to rotate. When the two sets of tower wheel assemblies 4 are running, the rotation direction of the two tower wheel bodies 42 is the same. The alloy wire is wound around the two tower wheel bodies 42. The alloy wire is wound in the tower wheel groove on the tower wheel body 42, and the rotation of the tower wheel body 42 provides a continuous and stable traction force to the wound alloy wire.

[0048] See Figures 4-6 The housing 12 is equipped with a die base assembly 5, which is located between two roller assemblies 4. The die base assembly 5 includes an I-beam frame 51 and multiple wire drawing dies 546. The wire drawing dies 546 are arranged according to the diameter variation of the roller body 42. The wire drawing dies 546 are used to draw the alloy wire, so that the alloy wire can achieve the purpose of diameter reduction and diameter setting.

[0049] Specifically, the alloy wire guided by the wire guide assembly 2 enters the interior of the housing 12 and is then threaded through one of the optional wire drawing dies 546, with a suitable length reserved. The alloy wire is then wound sequentially into the top grooves of the outer walls of the first and second cam bodies 42. After passing through the outer wall of the groove of the second cam body 42, the alloy wire passes under the groove of the first cam body 42 again and is then threaded through the next wire drawing die 546. The alloy wire is then wound again into the top grooves of the outer walls of the first and second cam bodies 42, and so on, until the winding of the cam grooves on the outer walls of the cam bodies 42 is completed. After winding, the alloy wire enters the interior of the winding box 31 through the exit die 32, and then the winding assembly 3 is used for wire guiding and winding operations.

[0050] During the winding process of the alloy wire, the two roller bodies 42 rotate synchronously, thereby providing traction force for the alloy wire drawn in the drawing die 546. In addition, in order to avoid equipment wear and thermal brittleness of the alloy wire during drawing, drawing oil is sprayed on the surface of the drawing die 546 and the roller body 42, which can play a role in lubrication and cooling. The housing 12 can also carry and collect the used drawing oil.

[0051] In Example 2, the horizontal die holder is oscillating within the drawing device to adjust its tilt angle. This allows for horizontal drawing of the alloy wire without the need for contouring, effectively avoiding high costs. However, some pulleys have a non-uniform stepped structure, meaning they are not conventional conical structures. Their diameter decreases at inconsistent rates, and their conical cross-sections are curved. This special structure means that even if the angle of the horizontal die holder is adjusted, the drawing die 546 cannot be properly matched with the pulley groove position, making the oscillating tilting method of the horizontal die holder unsuitable.

[0052] Therefore, further improvements were made to the mold base assembly 5.

[0053] See Figures 6-11 A square support rod 52 is connected to one side of the I-beam frame 51. A locking bolt 55 is threaded between the I-beam frame 51 and the inner wall of the box 12. The I-beam frame 51 is installed on the inner wall of the box 12 by the locking bolt 55. Multiple modular mechanisms 54 are provided on the outer wall of the square support rod 52. The multiple modular mechanisms 54 are placed with the assistance of the square support rod 52.

[0054] See Figures 6-11 The specific structure of module 54 is as follows: Each module mechanism 54 includes a connecting block 541 and a through groove 542 opened on the side wall of the connecting block 541. A square support rod 52 passes through the inside of the through groove 542. Each wire drawing die 546 is set on the top of the corresponding connecting block 541. Each connecting block 541 corresponds to one wire drawing die 546. When the connecting block 541 is fitted onto the outside of the square support rod 52, multiple connecting blocks 541 fall due to gravity and are at the same height. In this state, multiple wire drawing dies 546 are also horizontally arranged. At this time, the wire drawing die 546 can be used with a single diameter drum-type tower wheel body 42, and the length of different tower wheel bodies 42 will be different. Therefore, the number of connecting blocks 541 will also be spliced ​​according to the requirements.

[0055] See Figures 6-11 The top of the connecting block 541 has two placement slots 547. The wire drawing die 546 is placed inside one of the placement slots 547 on the top of the corresponding connecting block 541. The side walls of the connecting block 541 and the side walls of the placement slots 547 are provided with wire grooves 545. The inside of the wire grooves 545 is chamfered. When the wire drawing die 546 is placed on the top of the connecting block 541, the wire drawing die 546 is stuck inside the placement slot 547. When the alloy wire passes through the wire drawing die 546, it first passes through the wire groove 545 and then through the chamfer inside the wire groove 545, which helps to guide the alloy wire. That is, after the alloy wire passes through the wire groove 545, it can return to the position opposite to the die hole of the wire drawing die 546, reducing the degree of left and right tilt.

[0056] See Figure 6 and Figure 7 The die base assembly 5 also includes two sets of locking mechanisms 53 symmetrically installed on the side wall of the I-beam frame 51. The square support rod 52 is located between the two sets of locking mechanisms 53. After the multiple connecting blocks 541 are arranged, the two sets of locking mechanisms 53 are used to lock the multiple connecting blocks 541, so that the multiple connecting blocks 541 can form a spliced ​​assembly, ensuring the stability between the multiple connecting blocks 541 during the drawing process of the alloy wire. The specific structure of the locking mechanism 53 is as follows: See Figures 6-11 Both sets of locking mechanisms 53 include an L-shaped plate 531. The side wall of the L-shaped plate 531 is provided with a sliding groove 532. The side of the sliding groove 532 away from the square support rod 52 is rotatably connected to a two-way screw rod 534. The outer side wall of the two-way screw rod 534 is threaded with two clamping plates 533. The two clamping plates 533 pass through the interior of the corresponding sliding groove 532. The side wall of the I-beam frame 51 is equipped with a slot 535. One side of the L-shaped plate 531 passes through the interior of the slot 535.

[0057] After multiple connecting blocks 541 are fitted onto the outer wall of the square support rod 52, one end of each of the two L-shaped plates 531 is inserted into the corresponding slot 535. The multiple connecting blocks 541 are placed between the two L-shaped plates 531. Then, by rotating the bidirectional lead screw 534, the two clamping plates 533 slide closer to each other inside the corresponding sliding groove 532, thereby splicing and pressing the multiple connecting blocks 541 together. After that, the workers can perform the wire threading operation on the tower wheel body 42 and the wire drawing die 546 to facilitate the subsequent drawing of the alloy wire.

[0058] When the tower wheel body 42 is a non-uniform stepped type or a multi-stage cylindrical combination type, the multiple connecting blocks 541 are not arranged horizontally. There are two top columns 544 symmetrically connected at the bottom of the connecting blocks 541. The workers first put the multiple connecting blocks 541 onto the outside of the square support rod 52, and then install the locking mechanism 53. At this time, the locking mechanism 53 only guides the multiple connecting blocks 541 but does not lock them.

[0059] Subsequently, the staff placed the mold base assembly 5 on top of the tower wheel assembly 4, with each connecting block 541 corresponding to the tower wheel groove on the outer wall of the tower wheel body 42. The two top posts 544 at the bottom of each connecting block 541 were inserted into the corresponding tower wheel groove. Then, by pressing the tower wheel body 42 downwards with the mold base assembly 5, the multiple connecting blocks 541 were misaligned, and the change in misalignment height matched the shape of the tower wheel body 42. After adjustment, the two-way lead screw 534 was rotated, causing the two clamping plates 533 to slide closer to each other inside the corresponding sliding groove 532, thereby squeezing and fixing the splicing group of multiple connecting blocks 541, maintaining the splicing misalignment height of the multiple connecting blocks 541. This misalignment height is adapted to the selected tower wheel body 42 shape (not a proportional stepped type or a multi-level cylindrical combination type).

[0060] Afterwards, the staff installed the I-beam frame 51 on the inner wall of the box 12 and positioned it by locking bolts 55. Then, the staff can perform wire threading operations on the tower wheel body 42 and the wire drawing die 546 to facilitate the subsequent drawing of alloy wire.

[0061] By setting multiple connecting blocks 541, the mold base assembly 5 can be matched according to the shape of the tower wheel body 42. Not only is it not necessary to process the mold base according to the shape of the tower wheel body 42 or adjust the tilt to adjust the angle of the mold base, but it can also be used for non-uniform stepped tower wheel bodies 42.

[0062] Meanwhile, in the actual drawing process, although the alloy wire needs to be reduced in diameter by the drawing die 546, once the drawing die 546 is worn unevenly, its service life will be greatly reduced. The staff needs to repeatedly adjust the position of the drawing die 546 to reduce the degree of uneven wear, but adjusting it manually will result in a large error.

[0063] By setting the chamfer of the wire groove 545 and adjusting the height of the connecting block 541, the relative position of the die hole of the wire drawing die 546 and the pulley groove of the pulley body 42 can be further adjusted. That is, when the alloy wire enters the die hole of the wire drawing die 546, the chamfer of the wire groove 545 is used to limit the left and right tilt position, and by adjusting the height of the connecting block 541, the relative position of the alloy wire extending from the pulley groove and the height of the die hole of the wire drawing die 546 can be adjusted, reducing the wear when the alloy wire enters the die hole of the wire drawing die 546.

[0064] In Example 3, after improving the mold base assembly 5, it was also considered that the different widths and spacings of the tower wheel grooves of different tower wheel bodies 42 would cause changes in the spacing of the alloy wire winding. Therefore, the conventional splicing of the connecting block 541 is not entirely applicable to the use of different tower wheel bodies 42.

[0065] For this purpose, please refer to Figures 9-11 The module mechanism 54 also includes a guide mechanism 543 installed on one side of the connecting block 541. Two limiting grooves 548 are opened on the side of the connecting block 541 away from the guide mechanism 543. The guide mechanism 543 is inserted into the two limiting grooves 548. The guide mechanism 543 is used to connect the two connecting blocks 541, and the two adjacent connecting blocks 541 slide through the guide mechanism 543, so that the two connecting blocks 541 can be staggered vertically while completing the splicing, thereby realizing the staggered adjustment of the connecting blocks 541 according to the shape of the tower wheel body 42.

[0066] The specific structure of the guide mechanism 543 is as follows: See Figures 9-11The guiding mechanism 543 includes two guide posts 5431, each with a connecting plate 5434 connected to its outer side wall. The connecting block 541 has two limiting grooves 548 on its side wall. The connecting plate 5434 is inserted into the corresponding limiting groove 548, and a notch is provided at the bottom of the connecting plate 5434. When the connecting plate 5434 is inserted into the corresponding limiting groove 548, this notch allows for fitting and connection between the bottom wall of the limiting groove 548 and the bottom of the connecting block 541. A fixing plate 5432 connects the two connecting plates 5434, and an auxiliary bolt 5 is threaded to the bottom of the fixing plate 5432. 433, The bottom of the connecting block 541 is provided with a groove 5436, and the auxiliary bolt 5433 is inserted into the groove 5436. When the connecting plate 5434 is inserted into the limiting groove 548, the fixing plate 5432 is located below the corresponding connecting block 541, and the auxiliary bolt 5433 is screwed into the bottom of the fixing plate 5432. By screwing the auxiliary bolt 5433, the auxiliary bolt 5433 is inserted into the groove 5436 and squeezes the inner wall of the groove 5436. At this time, the fixing plate 5432 and the connecting plate 5434 are pushed down in the opposite direction, thereby pressing the connecting plate 5434 into the corresponding limiting groove 548.

[0067] See Figures 9-11 Two guide grooves 5435 are provided on the side of the connecting block 541 away from the connecting plate 5434. The guide grooves 5435 are adapted to the shape of the corresponding guide post 5431 and connecting plate 5434 combination. The guide post 5431 and connecting plate 5434 are adapted to the guide grooves 5435 on the side wall of the adjacent connecting block 541. When the two connecting blocks 541 are spliced ​​together, the connecting block 541 with the guide mechanism 543 is misaligned and fitted with the other connecting block 541, and the guide mechanism 543 is inserted upward from the bottom of the guide groove 5435 on the adjacent connecting block 541, thereby realizing the splicing of the two connecting blocks 541.

[0068] Specifically, the lengths of the selected tower wheel bodies 42 will vary, so the number of connecting blocks 541 will also vary depending on the required splicing. Furthermore, the position of the tower wheel grooves on tower wheel bodies 42 of different lengths will also change. Therefore, after multiple connecting blocks 541 are spliced, by pulling adjacent connecting blocks 541, the guide mechanism 543 will compensate for the change in spacing. That is, the connecting plate 5434 is pulled out a certain length from the inside of the corresponding limiting groove 548, while the auxiliary bolt 5433 slides inside the corresponding groove 5436, ensuring that each... Each connecting block 541 can be positioned opposite to the tower wheel groove of the corresponding tower wheel body 42. Then, by rotating the auxiliary bolt 5433, the auxiliary bolt 5433 will push and squeeze the groove 5436 in the opposite direction, causing the fixing plate 5432 to move downward. At this time, the connecting plate 5434 squeezes the inner bottom wall of the corresponding limiting groove 548, thereby completing the overall fixation of the guide mechanism 543. That is, the spacing of multiple connecting blocks 541 is adjusted through the cooperation of the corresponding guide mechanism 543, thereby adapting to the use of tower wheel bodies 42 with different spacing tower wheel grooves.

[0069] Example 4: An alloy wire drawing process using the alloy wire drawing equipment described above, comprising the following steps: S1. Place the mold base assembly 5 on top of the tower wheel assembly 4, and guide and adjust the mold base assembly 5 according to the shape of the tower wheel assembly 4 so that the shape of the mold base assembly 5 matches that of the tower wheel assembly 4.

[0070] The more specific steps in S1 are as follows: S11. Select the same number of connecting blocks 541 according to the number of tower wheel grooves of the tower wheel body 42. Adjacent connecting blocks 541 are connected to each other through a guide mechanism 543. Specifically, the guide post 5431 and the connecting plate 5434 are inserted from the bottom of the guide groove 5435 opened on the side wall of the adjacent connecting block 541, thereby completing the splicing of the adjacent connecting blocks 541. After the multiple connecting blocks 541 are spliced, they form a splicing group and are simultaneously fitted onto the outer side wall of the square support rod 52.

[0071] S12, the square support rod 52 fits into the inner top wall of the through groove 542 on the side wall of each connecting block 541. After the fitting is completed, one end of the two L-shaped plates 531 is inserted into the corresponding slot 535. Multiple connecting blocks 541 are placed between the two L-shaped plates 531. The two clamping plates 533 on each L-shaped plate 531 are located at both ends of the splicing group of multiple connecting blocks 541. Then, the mold base assembly 5 is placed on top of the tower wheel assembly 4. Each connecting block 541 corresponds to the tower wheel groove on the outer wall of the tower wheel body 42. The two top posts 544 at the bottom of each connecting block 541 are inserted into the corresponding tower wheel groove.

[0072] S13. In addition, the lengths of the different tower wheel bodies 42 selected will be different, so the number of connecting blocks 541 will also be spliced ​​according to the requirements. Moreover, the position of the tower wheel groove of the tower wheel body 42 of different lengths will also change. Therefore, after multiple connecting blocks 541 are spliced, by pulling the adjacent connecting blocks 541, the guide mechanism 543 will compensate according to the change of spacing. That is, the connecting plate 5434 is pulled out from the inside of the corresponding limiting groove 548 by a certain length, and at the same time, the auxiliary bolt 5433 slides inside the corresponding groove 5436 to ensure that each connecting block 541 can be set opposite to the tower wheel groove of the corresponding tower wheel body 42. Then, by rotating the auxiliary bolt 5433, the auxiliary bolt 5433 will push and squeeze the groove 5436 in the opposite direction, causing the fixing plate 5432 to move downward. At this time, the connecting plate 5434 squeezes the inner bottom wall of the corresponding limiting groove 548, thereby completing the overall fixation of the guide mechanism 543.

[0073] S14. Then, by pressing the tower wheel body 42 downward as a whole by the mold base assembly 5, the multiple connecting blocks 541 can be misaligned, and the change in misalignment height matches the shape of the tower wheel body 42. After the adjustment is completed, by rotating the bidirectional lead screw 534, the two clamping plates 533 slide closer to each other inside the corresponding slide groove 532, thereby squeezing and fixing the splicing group of multiple connecting blocks 541, and maintaining the splicing misalignment height of multiple connecting blocks 541.

[0074] S2. Install the die holder assembly 5 between the two roller assemblies 4, and then the alloy wire is wound through the guide wire assembly 2, the die holder assembly 5 and the two roller assemblies 4.

[0075] The more specific steps of S2 are as follows: S21. Install the I-beam frame 51 on the inner wall of the housing 12 and position it using the locking bolts 55.

[0076] S22. After the alloy wire is unwound by the spool, it is sequentially wound onto the outer walls of the two guide rods 23, and then passes through the inside of the ceramic eye 24, the auxiliary guide wheel 26, and the inlet mold 27 to reach the inside of the housing 12. After that, it is threaded through the inside of one of the optional wire drawing dies 546, with a suitable length reserved. This wire drawing die 546 is placed in one of the placement slots 547 on the top of the corresponding connecting block 541. The alloy wire is sequentially wound into the top grooves of the outer walls of the first and second tower wheel bodies 42. After the alloy wire passes through the outer wall of the top groove of the second tower wheel body 42, it passes under the top groove of the first tower wheel body 42 again. Then it is threaded through a wire drawing die 546, which is placed in the placement slot 547 on the top of the corresponding connecting block 541. The alloy wire is sequentially wound into the top grooves of the outer walls of the first and second tower wheel bodies 42, and so on, until the winding of the top grooves of the outer walls of the tower wheel bodies 42 is completed.

[0077] S3. After the alloy wire is wound, it is wound up by the winding assembly 3.

[0078] The more specific steps for S3 are as follows: S31. After the alloy wire is wound, the alloy wire enters the inside of the take-up box 31 through the exit mold 32, passes above the constant speed wheel 33 and the bottom of the wire separating wheel 34, and then winds around the outer wall of the constant speed wheel 33 to reach the wire guide wheel. After that, the alloy wire passes the outer wall of the swing guide wheel 36 and is wound up by the take-up reel 37.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
