Description

Technical Field

[0001] This invention relates to the field of wire drawing equipment technology, and more specifically, to a wire drawing device and method for non-ferrous metal alloy materials. Background Technology

[0002] Non-ferrous metal alloy wires are core materials for electronic circuit interconnection, power transmission, and aerospace structural components. Their processing precision and mechanical properties directly determine the reliability of downstream products. Wire drawing, as a key process in the forming of such wires, requires step-by-step stretching through molds to achieve diameter reduction and performance control. The stability of the equipment directly affects product quality and production efficiency.

[0003] Most existing guide roller assemblies are integrated structures. As a key component for wire transmission and tension, the guide roller is prone to grooved wear due to continuous friction from the wire, especially in the guide roller groove contact area. When the wear depth exceeds 0.2mm from the guide roller edge, the entire guide roller assembly needs to be replaced, resulting in high spare parts costs and prolonged production line downtime. Furthermore, during high-speed wire drawing, the frictional heat generated between the wire and the guide roller, as well as the heat released by metal plastic deformation, are concentrated in the guide roller groove contact area, where the local temperature can reach 80-100℃ from the guide roller edge. If heat dissipation is not timely, it will lead to a thicker oxide layer on the wire surface and coarser internal grains, reducing conductivity and tensile strength. It will also accelerate the wear rate of the guide roller surface and may cause wire vibration, resulting in a straightness error exceeding 0.1mm / m from the guide roller edge, seriously affecting stable wire production. Summary of the Invention

[0004] This invention provides a non-ferrous metal alloy material drawing device and method, which solves the technical problems of high replacement cost of the pulley, complex maintenance and low cooling efficiency in related technologies.

[0005] This invention discloses a wire drawing device for non-ferrous metal alloy materials, comprising: A metal wire drawing machine, the metal wire drawing machine including a cabinet, a water tank installed on the cabinet, and drive shafts arranged on both sides inside the water tank; A modular tow wheel unit, the modular tow wheel unit including a splined sleeve disposed on the drive shaft, the splined sleeve being provided with a tow wheel module; The tower wheel module includes multiple sets of individual tower wheels mounted on a splined sleeve, and the multiple sets of individual tower wheels are connected by a snap-fit ​​connection. A wire drawing correction unit is disposed above the tow wheel module and is used to calibrate and correct the wire drawing material on the tow wheel module to avoid additional wear on the modular tow wheel unit.

[0006] As a further optimization of the present invention, the interior of the multiple sets of individual tower wheels is provided with spline grooves that are adapted to the spline sleeve, and the spline grooves and the spline sleeve are slidably connected. The multiple sets of individual tower wheels are arranged sequentially from small to large along the axial direction of the spline sleeve.

[0007] As a further optimization of the present invention, each of the multiple sets of individual tower wheels is equipped with a tower wheel edge, and each tower wheel edge is provided with multiple sets of water spray nozzles in a ring shape.

[0008] As a further optimization of the present invention, the interior of each of the multiple sets of tower wheels is provided with liquid flow channels corresponding to the water spray nozzles, and the liquid flow channels extend toward the sealing cover. The multiple sets of liquid flow channels inside each set of tower wheels extend into the interior of the other multiple sets of tower wheels. A liquid inlet plate is installed on the tail set of tower wheels, and the liquid inlet plate is provided with multiple sets of liquid inlet holes, the number of which is the same as the number of liquid flow channels.

[0009] As a further optimization of the present invention, the spline sleeve is also provided with a sealing cover plate, the edge of the sealing cover plate abutting against a group of individual tower wheels at the tail end, and a liquid supply mechanism is provided on the sealing cover plate.

[0010] As a further optimization of the present invention, the liquid supply mechanism includes a liquid supply tray sleeved outside the sealing cover plate, a liquid supply pipe installed on the liquid supply tray, and a plurality of liquid flow holes are formed in a ring on the sealing cover plate, the liquid flow holes being connected to the interior of the sealing cover plate.

[0011] As a further optimization of the present invention, the wire drawing and correction unit includes a connecting bracket disposed above the tower wheel module, the connecting bracket being provided with multiple sets of sliding blocks, and rollers being symmetrically disposed on the sliding blocks.

[0012] As a further optimization of the present invention, multiple sets of first hydraulic cylinders are installed on the connecting bracket, and the telescopic ends of the first hydraulic cylinders are fixedly connected to the sliding block.

[0013] As a further optimization of the present invention, the water tank is equipped with fixed frames on both sides, and a second hydraulic cylinder is installed on the fixed frame. The telescopic end of the second hydraulic cylinder is equipped with a sliding frame, and the sliding frame is fixedly connected to the connecting bracket.

[0014] Another aspect of this invention discloses a method for drawing non-ferrous metal alloy materials into wires, the steps of which are as follows: S1. Based on the diameter and material characteristics of the non-ferrous metal alloy wire to be drawn, select the corresponding specifications of the tower wheel individual for sliding assembly, and connect the liquid supply pipe to the external coolant source. S2. Wind the wire around each group of tractor units in ascending order of size; S3. During operation, coolant is sprayed from the nozzles of each individual tower wheel through the passage to pre-cool the edge of the tower wheel and the surface of the wire to be contacted, reducing the initial frictional temperature rise. Coolant is sprayed directionally from the corresponding nozzle of the tower wheel to the contact area between the wire and the edge of the tower wheel, specifically cooling the high heat area generated by high-speed stretching, and preventing the wire from deteriorating in performance or the tower wheel from overheating and wearing out. S4. During the wire drawing process, if the wire of one of the individual tower wheels is tilted, the first hydraulic cylinder of the corresponding sliding block will be activated, driving the sliding block to make a slight lateral adjustment and push the wire back to the correct path until the pressure on both sides returns to the reference. If the wires of multiple sets of rollers show a consistent tilting trend, the second hydraulic cylinder adjusts the overall position of the connecting bracket, simultaneously driving all sliding blocks and rollers to shift, thereby achieving coordinated correction of the global wire feeding path and avoiding secondary deviations caused by local adjustments.

[0015] The beneficial effects of this invention are as follows: By adopting a modular tower wheel unit, the tower wheel is designed as multiple sets of interlocking tower wheel individuals. When one set of tower wheel individuals wears out, only the worn individual needs to be replaced, without replacing the entire tower wheel, which greatly reduces maintenance costs and replacement time, and improves equipment utilization and production efficiency. Furthermore, because the tower wheel individuals are arranged from small to large, the larger tower wheels and the rearmost tower wheels have more internal fluid flow channels, which facilitates the passage of coolant and heat dissipation. This allows the coolant to be sprayed directly onto the contact area between the wire and the edge of the tower wheel through the spray nozzle, achieving targeted local cooling. This effectively removes a large amount of heat generated during the wire drawing process, preventing the wire from overheating and causing performance degradation, while also extending the service life of the tower wheel.

Detailed Implementation

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] Example 1: According to the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the present invention provides a non-ferrous metal alloy material drawing device, including a metal drawing machine 100, a tension adjusting device 200, a winding device 300, a modular pulley unit 400, and a drawing correction unit 500.

[0020] The metal wire drawing machine 100 includes a cabinet 110, on which a water tank 120 is installed. Drive shafts 130 are arranged on both sides inside the water tank 120. A wire drawing die frame 140 is arranged between the two sets of drive shafts 130 for installing wire drawing dies of different specifications. Wire drawing inlet 150 and wire drawing outlet 160 are respectively arranged on both sides of the water tank 120 for wire to enter and exit.

[0021] Both the tension adjusting device 200 and the winding device 300 are installed on the cabinet 110. The tension adjusting device 200 is used to control the tension of the wire during the drawing process, and the winding device 300 is used to wind up the stretched wire.

[0022] Among them, according to the appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, the modular tractor unit 400 is one of the core components of this invention. It includes a splined sleeve 410 mounted on the drive shaft 130, a tractor module 420 mounted on the splined sleeve 410, and a tractor module 420 comprising multiple sets of individual tractor wheels 421 mounted on the splined sleeve 410. The multiple sets of individual tractor wheels 421 are connected by a snap-fit ​​connection. It should be noted that the snap-fit ​​connection facilitates the assembly of multiple sets of individual tractor wheels 421, so that when one set wears out, only the worn set needs to be replaced, without replacing the entire tractor wheel assembly, greatly reducing maintenance costs and time.

[0023] To further refine the engagement connection method, the multiple sets of individual tow wheels 421 can be divided into a first unit, a second unit, a third unit, a fourth unit, a fifth unit, a sixth unit, a seventh unit, an eighth unit, and a ninth unit. Each of the first, second, third, fourth, fifth, sixth, seventh, and eighth units is equipped with a locking block, while each of the second, third, fourth, fifth, sixth, seventh, eighth, and ninth units has a locking slot. Each pair of adjacent tow wheel units 421 is engaged and connected via the locking slots and locking blocks, ensuring a stable connection between the tow wheel units.

[0024] In a preferred embodiment, according to the appendix Figure 5 Appendix Figure 6 and attached Figure 7 As shown, the interior of multiple sets of pulley individuals 421 is provided with spline grooves that are compatible with the spline sleeve 410, and the spline grooves and spline sleeve 410 are slidably connected. The multiple sets of pulley individuals 421 are arranged sequentially from small to large along the axial direction of the spline sleeve 410, so that pulley individuals of different specifications can be flexibly combined according to wire drawing requirements, and are easy to disassemble and replace.

[0025] To achieve efficient cooling, according to the attached... Figure 6 Appendix Figure 7 and attached Figure 8As shown, each of the multiple sets of tower wheel individuals 421 is equipped with a tower wheel edge 422, and each tower wheel edge 422 has multiple sets of water spray nozzles 423 arranged in a ring. The interior of each set of tower wheel individuals 421 has liquid flow channels 424 corresponding to the water spray nozzles 423, and these channels 424 extend towards the sealing cover plate 430. The multiple sets of liquid flow channels 424 inside each set of tower wheel individuals 421 extend into the interior of the other sets of tower wheel individuals 421. A liquid inlet plate 425 is installed on the rear set of tower wheel individuals 421, and the liquid inlet plate 425 has multiple sets of liquid inlet holes 426, the number of which is the same as the number of liquid flow channels 424. Because the tower wheel individuals 421 are arranged from smallest to largest, the larger and rearmost tower wheels have more liquid flow channels 424 inside, facilitating the passage of coolant and heat dissipation. This design can provide differentiated coolant flow rates according to the heat dissipation requirements of different sized tower wheels, achieving precise cooling.

[0026] Furthermore, according to the appendix Figure 7 and attached Figure 8 As shown, a sealing cover plate 430 is also provided on the spline sleeve 410, and a connecting sleeve 440 is installed on the sealing cover plate 430. The connecting sleeve 440 is located outside the spline sleeve 410, and multiple sets of fastening bolts 450 are provided on the outside of the connecting sleeve 440. The fastening bolts 450 pass through the connecting sleeve 440 and are threadedly connected to the spline sleeve 410 to fix the sealing cover plate 430 on the spline sleeve 410. The edge of the sealing cover plate 430 abuts against a set of individual tower wheels 421 at the tail to form a seal. A liquid supply mechanism 460 is provided on the sealing cover plate 430.

[0027] Specifically, according to the appendix Figure 9 As shown, the liquid supply mechanism 460 includes a liquid supply tray 461 sleeved outside the sealing cover plate 430. The liquid supply tray 461 has a liquid supply chamber inside, and a liquid supply pipe 462 is installed on the liquid supply tray 461 and connected to the interior of the liquid supply chamber for introducing external coolant. Annular slide rails 463 are slidably connected to both sides of the interior of the liquid supply chamber, and the annular slide rails 463 are mounted on the sealing cover plate 430. The sealing cover plate 430 has multiple sets of liquid flow holes 464 arranged in a ring shape, and the liquid flow holes 464 are located between two sets of annular slide rails 463. The liquid flow holes 464 are connected to the interior of the sealing cover plate 430. This liquid supply mechanism 460 is used to supply liquid to the inside of the spray nozzle 423, so that the spray nozzle 423 sprays liquid to cool the wire drawing process.

[0028] According to the appendix Figure 10 and attached Figure 11As shown, the wire drawing correction unit 500 is positioned above the pulley module 420 to calibrate and correct the wire drawing material on the pulley module 420, thereby preventing additional wear on the modular pulley unit 400. The wire drawing correction unit 500 includes a connecting bracket 510 positioned above the pulley module 420. The connecting bracket 510 has a stepped structure to accommodate pulleys of different heights. Multiple sets of sliding blocks 520 are provided on the connecting bracket 510, and rollers 530 are symmetrically arranged on the sliding blocks 520. The rollers 530 and sliding blocks 520 are rotatably connected via bearings to ensure flexible roller rotation. The number of sliding blocks 520 is the same as the number of pulleys 421, meaning each pulley 421 has a corresponding set of sliding blocks and rollers.

[0029] In a preferred embodiment, a piezoelectric pressure sensor is provided on the roller 530. This sensor can monitor the contact pressure between the wire and the roller in real time, providing data support for wire alignment.

[0030] According to the appendix Figure 11 As shown, multiple sets of first hydraulic cylinders 540 are installed on the connecting bracket 510. The telescopic end of the first hydraulic cylinder 540 is fixedly connected to the sliding block 520. The number of first hydraulic cylinders 540 and sliding blocks 520 is the same. When the sensor detects that the wire feeding path is deviated, the corresponding first hydraulic cylinder 540 will drive the sliding block 520 to move laterally, thereby adjusting the position of the roller 530 and performing local correction of the wire.

[0031] To achieve global alignment correction, fixed brackets 550 are installed on both sides of the water tank 120, and second hydraulic cylinders 560 are mounted on the fixed brackets 550. A sliding bracket 570 is installed on the telescopic end of the second hydraulic cylinder 560, and the sliding bracket 570 is fixedly connected to the connecting bracket 510. When it is necessary to adjust the wire feeding path of the entire tower wheel module, the second hydraulic cylinder 560 drives the sliding bracket 570, thereby causing the connecting bracket 510 and all its sliding blocks 520 and rollers 530 to move as a whole, achieving global alignment correction.

[0032] Example 2: According to the appendix Figure 1 To be continued Figure 11 As shown, this embodiment provides a method for drawing non-ferrous metal alloy materials into wires, which uses the non-ferrous metal alloy material drawing device described in Embodiment 1. The specific steps are as follows: Step 1: Individual assembly of the tower wheel; Based on the diameter and material characteristics of the non-ferrous metal alloy wire to be drawn, select the corresponding specifications of the pulley individual 421, connect multiple sets of pulley individuals 421 by locking blocks and slots, and then slide them onto the spline sleeve 410 in order from small to large along the axial direction of the spline sleeve 410.

[0033] After assembly, the sealing cover plate 430 is fixed to the tail of the spline sleeve 410 by the connecting sleeve 440 and the fastening bolt 450, so that the edge of the sealing cover plate 430 abuts and seals with the tail tower wheel individual 421 to ensure that the coolant circuit does not leak. Connect the liquid supply pipe 462 to the external coolant source, check the connectivity between the liquid flow channel 424 and the water spray nozzle 423, and ensure that the coolant can enter the interior of each tower wheel individual 421 through the liquid supply plate 461 and the liquid flow hole 464.

[0034] Step 2: Threading the wires; The non-ferrous metal alloy wire to be processed is inserted into the water tank 120 through the wire drawing inlet 150, and then sequentially passes through the corresponding specification wire drawing dies on the wire drawing die frame 140.

[0035] Subsequently, the wire is wound around each group of tower wheel individuals 421 in ascending order of size. After the wire is drawn out from the tower wheel module 420, it is connected to the tension adjustment device 200 through the wire drawing outlet 160. The tension adjustment device 200 is adjusted to the initial tension value, and finally the end of the wire is fixed to the winding shaft of the winding device 300.

[0036] Step 3: Cooling; Start the metal wire drawing machine 100. During operation, the coolant passes through the liquid supply mechanism 460, the liquid flow hole 464, and the liquid flow channel 424, and is finally sprayed out from the spray nozzle 423 of each individual tower wheel 421 to pre-cool the tower wheel edge 422 and the surface of the wire to be contacted, thereby reducing the initial frictional temperature rise.

[0037] During the wire drawing process, due to the arrangement of individual tower wheels 421 from small to large, the larger-sized tower wheels in the later stage bear a greater amount of wire stretching and generate more significant frictional heat. They also have more internal fluid flow channels 424, which can carry more coolant, thereby achieving targeted and efficient heat dissipation. The coolant is sprayed directionally through the corresponding tower wheel nozzles 423 to the contact area between the wire and the edge of the tower wheel, specifically cooling the high-heat area generated by high-speed stretching, and preventing the wire from deteriorating in performance due to overheating or the tower wheel from overheating and wearing out.

[0038] Step 4: Correction; During the wire drawing process, the wire drawing correction unit 500 monitors the wire feeding path in real time. If the wire tilts due to errors in the parallelism of the rollers or deviations in the feeding path, the contact pressure between the roller 530 on one side and the wire will increase, while the pressure on the other side will decrease, deviating from the initial reference value. The piezoelectric pressure sensor on the roller 530 captures this pressure difference in real time and converts the signal into a basis for judging the direction and degree of tilt.

[0039] If only the wire of a certain group of tower wheel individual 421 is tilted, the control system will activate the first hydraulic cylinder 540 of the corresponding sliding block 520 according to the sensor signal. The first hydraulic cylinder 540 drives the sliding block 520 to make a slight lateral adjustment, so that the roller 530 applies a symmetrical constraint force to the wire, pushing the wire back to the correct path until the pressure on both sides returns to the reference.

[0040] If the wires of multiple sets of rollers show a consistent tilting trend, the control system will activate the second hydraulic cylinder 560. The second hydraulic cylinder 560 adjusts the overall position of the connecting bracket 510, and simultaneously drives all sliding blocks 520 and rollers 530 to shift, thereby achieving coordinated correction of the global wire feeding path and avoiding secondary deviations caused by local adjustments.

[0041] The embodiments of this specific implementation have been described above. However, this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
