Description

Technical Field

[0001] This application relates to the field of wire drawing equipment technology, and in particular to an alloy large drawing machine for aluminum alloy wire drawing. Background Technology

[0002] Aluminum alloy wire drawing is a process that utilizes the plastic deformation capacity of aluminum alloys. Under the traction force of a wire drawing machine, aluminum alloy wires are repeatedly passed through die holes of specific sizes, causing the aluminum alloy wires to be stretched and deformed to obtain wires of a specific diameter. Aluminum alloy wires drawn by the wire drawing die are widely used in aerospace, electronics, building decoration, automotive industry, cable conductors and other fields (such as high-voltage wiring harnesses for new energy vehicles, mobile phone antennas, and door and window frame wires).

[0003] However, in existing aluminum alloy wire drawing equipment, when the aluminum alloy wire passes through the die hole of the drawing die, it undergoes plastic deformation, and a small amount of material falls off the surface to form aluminum chips. These particles adhere to the inside of the die hole, and as the wire continues to rub against the inner wall of the die hole, the temperature rises. The short time required for each wire roll to be changed during drawing is insufficient for cooling. Over time, the aluminum chips and the die surface are prone to "metallurgical bonding" to form a firmly attached film layer. This film layer affects the surface flatness of the aluminum alloy wire, resulting in poor quality of the aluminum alloy wire. Summary of the Invention

[0004] This application proposes an alloy drawing machine for aluminum alloy wire drawing, which has the advantages of ensuring high wire drawing quality during long-term operation and long service life of the drawing die. It solves the problem that existing wire drawing equipment is prone to affecting the wire drawing quality and the service life of the drawing die due to the film layer on the inner wall of the die hole when drawing aluminum alloy wire.

[0005] To achieve the above objectives, this application adopts the following technical solution: an alloy drawing machine for aluminum alloy wire drawing, comprising:

[0006] Two rotating components are mounted on a support platform, each driven to rotate by two gears mounted on the support platform. Two moving components are symmetrically arranged on each rotating component. One end of the moving component on one rotating component is fixedly mounted with a first mold, and one end of the moving component on the other rotating component is fixedly mounted with a second mold. A hydraulic cylinder for moving the first and second molds is also fixedly mounted on the support platform. A cleaning device located on one side of the two rotating components is fixedly mounted on the top of the support platform.

[0007] After the first and second dies on the two rotating components move towards each other, they close to form a complete wire drawing die. The other first and second dies are respectively close to two cleaning devices. Each time a new roll of aluminum alloy wire is changed for wire drawing, the rotating components are driven by a servo motor to rotate and the two first and second dies on them are swapped. The cleaning devices temporarily clean the die holes of the separated first and second dies.

[0008] Furthermore, the rotating assembly includes a rotating ring fixedly mounted on a top planar bearing of the support platform. A gear ring is fixedly fitted onto the outer edge of the bottom of the rotating ring. The output shafts of two servo motors extend above the support platform and are respectively fixedly mounted with gears. The outer teeth of the two gears mesh with the two gear rings. A rotating plate is fixedly mounted on the top of the gear rings. The moving assembly is fixedly mounted on the outer edge of the rotating plate. The two servo motors synchronously drive the output shafts to rotate the two gears respectively. By utilizing the meshing action of the gears and gear rings, the rotating ring, gear rings, and rotating plate are rotated together, thereby causing the two moving assemblies to rotate and change positions, thus changing the positions of the two first and second parting dies. This allows one of the first and second parting dies to be used for die closing to perform wire drawing on the aluminum alloy wire. After the other first and second parting dies are separated, their die holes are temporarily cleaned by two cleaning devices, improving the service life of the wire drawing die and the quality of subsequent wire drawing.

[0009] Furthermore, the moving component includes two positioning blocks, which are fixedly installed on the top and bottom of the rotating plate, respectively. Sliding shafts are movably sleeved on the two positioning blocks. Two symmetrically arranged sliding grooves are opened on the inner side of the rotating plate. A moving plate located in the sliding groove is fixedly installed at one end of the two sliding shafts. Two springs are arranged between the moving plate and the two positioning blocks, and the two springs are movably sleeved on the outer side of the sliding shafts. The first mold and the second mold are fixedly connected to the end of the sliding shaft away from the moving plate. Through the elastic force of the springs, the first mold and the second mold tend to move towards the central axis of the rotating plate under normal conditions, so that the rotating plate drives the first mold and the second mold to rotate and separate, or to gradually close the mold by using the drive of the hydraulic cylinder.

[0010] Furthermore, the side of the movable plate does not contact the inside of the chute, so that the inner wall of the chute will not affect the movement of the movable plate.

[0011] Furthermore, two support seats are fixedly installed on the top of the support platform. The two support seats are located inside the rotating plate, and two hydraulic cylinders are fixedly installed on the support seats. One end of the piston shaft of the two hydraulic cylinders faces the two sliding grooves inside the rotating plate. By setting the two hydraulic cylinders inside the rotating plate, the piston shafts are driven by the hydraulic cylinders to extend and push the moving plate and sliding shaft to move. This can control the first and second parting molds to move away from the central axis of the rotating plate. Moreover, by driving the piston shafts to retract, the piston shafts of the hydraulic cylinders are located inside the rotating plate without affecting the rotation of the rotating plate.

[0012] Furthermore, the first parting die has a mold groove on the side facing the second parting die, located on the upper and lower sides of the drawing die hole, and the mold groove is a semi-circular groove. The second parting die has a protruding plate fixedly installed on the side facing the first parting die, located on the upper and lower sides of the die hole. The protruding plate is a semi-circular plate and is adapted to the mold groove. The two protruding plates are movably connected to the two mold grooves respectively. After the first parting die and the second parting die are spliced ​​to form a drawing die, the protruding plate is inserted into the interior of the mold groove. After the first parting die and the second parting die are closed, the integrity of the die hole is ensured, so as not to affect the drawing quality of the aluminum alloy wire.

[0013] Furthermore, the top of the support platform is provided with a limiting device located below the first and second parting molds. The limiting device includes a U-shaped slider movably installed on the top of the support platform. Two linkage plates are fixedly installed at one end of the U-shaped slider. The bottom ends of the two linkage plates extend to the bottom of the support platform and are fixedly connected to a positioning plate. A through groove is provided on the support platform to be movably connected to the linkage plates. A servo cylinder is fixedly installed at the bottom of the support platform on one side of the positioning plate. The piston shaft of the servo cylinder is fixedly connected to the positioning plate. The servo cylinder drives the piston shaft to move the positioning plate, thereby moving the linkage plate and the U-shaped slider together. After the first and second parting molds are closed, the servo cylinder drives the U-shaped slider to move towards the wire drawing die, so that the two sides of the U-shaped slider are respectively attached to the outer sides of the first and second parting molds. With the limiting of the convex plate by the mold groove, the first and second parting molds are always in a stable closed state after the aluminum alloy wire passes through the mold hole of the wire drawing die.

[0014] Furthermore, the cleaning device includes two support plates fixedly installed on the top of the support platform, with a rotatable rotating roller between the two support plates. A cleaning motor that drives the rotating roller to rotate is fixedly installed on one of the support plates, and a cleaning brush is provided on the outer side of the rotating roller. When the wire drawing operation is performed after one of the first and second parting dies on the two rotating plates is closed, the other first and second parting dies on the two rotating plates face the cleaning brush respectively. A piston shaft driven by another hydraulic cylinder on the support base pushes the first and second parting dies to move towards the cleaning brush. The rotating roller is driven by the cleaning motor to rotate, and the cleaning brush is used to temporarily clean the die holes of the first and second parting dies, thereby helping to improve the service life of the wire drawing die and effectively ensuring the subsequent wire drawing quality.

[0015] Furthermore, at least one nozzle is fixedly installed on another support plate, with its nozzle facing the mold hole of the first or second mold. When temporarily cleaning the mold hole of the first or second mold, the high-pressure gas or cleaning solvent sprayed from the nozzle can be used in conjunction with the rotation of the cleaning brush to further improve the cleaning effect.

[0016] Furthermore, a third parting mold is fixedly installed on one side of the first parting mold, and a fourth parting mold is fixedly installed on one side of the second parting mold. The middle part of the opposite side of the third and fourth parting molds is designed with a smooth slope. After the first and second parting molds are closed, the slopes of the third and fourth parting molds are spliced ​​together. The mold hole after the third and fourth parting molds are closed corresponds to the mold hole after the first and second parting molds are closed. When the production process technology and cost of the wire drawing die are low, and there is still a small gap in the mold hole after the first and second parting molds are closed, the addition of the third and fourth parting molds can further ensure the quality of aluminum alloy wire drawing and prevent the problem of protrusions on the wire drawing surface due to the gap in the mold hole.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This application provides an alloy drawing machine for aluminum alloy wire drawing, which uses two rotatable rotating components and two first and second dividing dies symmetrically arranged on the outer edges of the two rotating components. The first and second dividing dies are used together for aluminum alloy wire drawing. After the other first and second dividing dies are separated, they are temporarily cleaned by a cleaning device set on the support platform to remove the debris and adhesive layer in the die hole in time. This avoids the problem of the wire drawing surface being rough due to the debris and adhesive layer in the die hole when the existing wire drawing die is used for a long time. This improves the quality of aluminum alloy wire drawing. After the wire drawing is completed, it is more convenient to disassemble the die for cleaning and maintenance. Furthermore, by controlling the repositioning of the two first and second dividing dies each time a new roll of aluminum alloy wire is drawn, the wire drawing efficiency will not be affected.

[0019] 2. The aluminum alloy wire drawing machine provided in this application has a structural design in which two rotating components can rotatably cooperate to form a first parting die and a second parting die. After the first parting die and the second parting die are separated, the die holes are temporarily cleaned by cleaning devices. Compared with existing wire drawing dies, the exposed half die holes are more convenient for internal cleaning, which helps to improve the cleaning effect of the die holes. At the same time, it provides sufficient time for the wire drawing die to cool down, avoiding the problem that existing wire drawing dies are prone to overheating and reduced lifespan due to continuous operation.

[0020] 3. The first and second molds are driven by hydraulic cylinders to approach each other and close the mold, which facilitates the initial threading of each roll of aluminum alloy wire and thus improves the wire drawing efficiency. Attached Figure Description

[0036] 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.

[0037] Example 1, as Figures 1-5A large alloy drawing machine for aluminum alloy wire drawing includes a support platform 1. Two rotatable rotating components 2 are fixedly mounted on the top of the support platform 1 via a plane bearing. The rotating components 2 include a rotating ring 201 fixedly mounted on the plane bearing at the top of the support platform 1. A gear ring 202 is fixedly fitted on the outer edge of the bottom of the rotating ring 201. Two servo motors 3 are fixedly mounted on the bottom of the support platform 1. The output shafts of the two servo motors 3 extend above the support platform 1 and are respectively fixedly mounted with gears 4. The outer teeth of the two gears 4 mesh with the two gear rings 202. The servo motors 3 drive the output shafts to rotate the gears 4, which in turn drive the rotating ring 201 and the gear ring 202 to rotate. A rotating plate 203 is fixedly mounted on the top of the gear ring 202. Two symmetrically arranged moving components 5 are fixedly mounted on the outer edge of the rotating plate 203.

[0038] Please see Figure 4 , Figures 6-7 The moving component 5 includes two positioning blocks 501, which are fixedly mounted on the rotating plate 203. Sliding shafts 502 are movably sleeved on the two positioning blocks 501 respectively. Two symmetrically arranged sliding grooves 2031 are opened on the inner side of the rotating plate 203. A moving plate 503 located in the sliding groove 2031 is fixedly mounted on one end of the two sliding shafts 502. The side of the moving plate 503 does not contact the inner side of the sliding groove 2031, so that the rotating plate 203 will not affect the movement of the moving plate 503 in the sliding groove 2031. Two springs 504 are arranged between the moving plate 503 and the two positioning blocks 501. The two springs 504 are movably sleeved on the outer side of the sliding shafts 502 respectively. The elastic force of the springs 504 causes the moving plate 503 to drive the two sliding shafts 502 to move towards the central axis of the rotating ring 201.

[0039] Please see Figures 1-3 , Figures 6-9Two support seats 7 are fixedly installed on the top of the support platform 1. The two support seats 7 are located inside the two rotating plates 203 respectively. Two hydraulic cylinders 8 are fixedly installed on the top of the support seats 7. One end of the piston shaft of the two hydraulic cylinders 8 faces the two sliding grooves 2031 inside the rotating plate 203 respectively. One end of the sliding shaft 502 in the moving component 5 on one rotating plate 203 is fixedly installed with a first parting 9, and one end of the sliding shaft 502 in the moving component 5 on the other rotating plate 203 is fixedly installed with a second parting 10. The hydraulic cylinders 8 on the two support seats 7 are... Do not push the piston shaft to drive the first parting mold 9 and the second parting mold 10 to move towards each other against the elastic force of the spring 504 until the first parting mold 9 and the second parting mold 10 are attached to form a complete wire drawing mold, and the middle part of the wire drawing mold is a complete mold hole. The outer diameter of the wire inlet of the mold hole decreases uniformly towards the middle so that the aluminum alloy wire can pass through the mold hole to form a finer wire. The first parting mold 9 and the second parting mold 10 are fixed to one end of the rotating plate 203 by bolts so that the first parting mold 9 and the second parting mold 10 can be disassembled. The wire drawing mold with the corresponding mold hole can be replaced according to the size of the aluminum alloy wire to be drawn.

[0040] The first mold 9 has a mold groove 901 on the side facing the second mold 10, located on the upper and lower sides of the mold hole. The mold groove 901 is a semi-circular groove. The second mold 10 has a protruding plate 101 fixedly installed on the side facing the first mold 9, located on the upper and lower sides of the mold hole. The protruding plate 101 is a semi-circular plate and is adapted to the mold groove 901. The two protruding plates 101 are movably connected to the two mold grooves 901 respectively. After the first mold 9 and the second mold 10 are spliced ​​to form a wire drawing mold, the protruding plate 101 is inserted into the mold groove 901. After the first mold 9 and the second mold 10 are closed, the integrity of the mold hole is ensured, so as not to affect the wire drawing quality of the aluminum alloy wire.

[0041] Please see Figures 1-2 , Figures 10-11The top of the support platform 1 is provided with a limiting device 11 located below the first mold parting 9 and the second mold parting 10. The limiting device 11 includes a U-shaped slider 111 movably mounted on the top of the support platform 1. Two linkage plates 112 are fixedly mounted on one end of the U-shaped slider 111. The bottom ends of the two linkage plates 112 extend to the bottom of the support platform 1 and are fixedly connected to a positioning plate 113. A through groove 6 is provided on the support platform 1 to be movably connected to the linkage plate 112. A servo cylinder 114 located on one side of the positioning plate 113 is fixedly mounted on the bottom of the support platform 1. The piston of the servo cylinder 114... The shaft is fixedly connected to the positioning plate 113. The piston shaft is driven by the servo cylinder 114 to move the positioning plate 113, thereby moving the linkage plate 112 and the U-shaped slider 111 together. After the first mold 9 and the second mold 10 are closed, the U-shaped slider 111 is driven by the servo cylinder 114 to move towards the wire drawing die, so that the two sides of the U-shaped slider 111 are respectively attached to the outer sides of the first mold 9 and the second mold 10. With the limit of the protrusion plate 101 by the mold groove 901, the first mold 9 and the second mold 10 are always in a stable mold closing state after the aluminum alloy wire passes through the mold hole of the wire drawing die.

[0042] Please continue reading. Figures 1-3 , Figure 12 Two cleaning devices 12 are fixedly installed on the top of the support platform 1. The two cleaning devices 12 are located on one side of the two rotating components 2 respectively. The cleaning device 12 includes two support plates 121 fixedly installed on the top of the support platform 1. A rotatable rotating roller 122 is arranged between the two support plates 121. A cleaning motor 123 for driving the rotating roller 122 is fixedly installed on one of the support plates 121. A cleaning brush 124 is provided on the outer side of the rotating roller 122. At least one nozzle 13 with its nozzle facing the mold hole of the first mold 9 or the second mold 10 is fixedly installed on the other support plate 121. When the first mold 9 and the second mold 10 on the two rotating plates 203 are closed and wire drawing is performed, the two rotating plates 203... The first parting die 9 and the second parting die 10 on the support 3 face the cleaning brush 124 respectively. The piston shaft driven by another hydraulic cylinder 8 on the support 7 pushes the first parting die 9 and the second parting die 10 toward the cleaning brush 124. The rotating roller 122 is driven by the cleaning motor 123 to rotate. The high-pressure gas or cleaning solvent sprayed by the cleaning brush 124 and the nozzle 13 is used to temporarily clean the mold holes of the first parting die 9 and the second parting die 10, which helps to improve the service life of the wire drawing die and effectively ensures the subsequent wire drawing quality. The cleaning brush 124 can be a nylon brush, or a nylon base with 10%-20% glass fiber / carbon fiber added, which will not damage the mold holes of the wire drawing die while ensuring hardness and wear resistance.

[0043] In use, firstly, the servo motor 3 drives the gear 4 to rotate the rotating plate 203, so that one of the first molds 9 and the second mold 10 on the two rotating plates 203 moves closer to each other. Then, one end of the aluminum alloy wire that needs to pass through the drawing die is passed through the middle die hole of the first mold 9 and the second mold 10 (the wire feeding, wire guiding, and wire take-up of the aluminum alloy wire to be drawn are not related to the inventive point of this invention and are existing known technologies, so they will not be described here). At the same time, one of the hydraulic cylinders 8 on the two support seats 7 is activated to drive the piston shaft to move the rotating plate 203, pushing the first mold 9 and the second mold 10 to gradually close the mold. At the same time, the aluminum alloy wire gradually becomes thinner as the first mold 9 and the second mold 10 close the mold, until the first mold 9 and the second mold 10 are completely closed. After the aluminum alloy wire passes through the middle die hole of the drawing die after the first mold 9 and the second mold 10 are closed, a fine wire of a stable diameter is formed.

[0044] When one roll of aluminum alloy wire is finished being drawn and another roll is switched to continue drawing, the hydraulic cylinder 8 drives the piston shaft to retract and move to the inside of the rotating plate 203. The elastic force of the spring 504 causes the first and second parting molds 9 and 10 to separate and move. The servo motor 3 drives the gear 4 to rotate the gear ring 202 and the rotating plate 203 together by half a turn, so that the previously closed first and second parting molds 9 and 10 are rotated to one side of the cleaning brush 124 respectively. Then, another hydraulic cylinder 8 on the support base 7 drives the piston shaft to push the first and second parting molds 9 and 10 toward the two cleaning brushes respectively. Move 124, start the cleaning motor 123 to drive the output shaft to drive the rotating roller 122 to rotate, and spray high-pressure air or cleaning solvent through the nozzle 13 toward the mold holes of the first mold 9 and the second mold 10 to temporarily clean the mold holes of the first mold 9 and the second mold 10. At the same time, the other first mold 9 and the second mold 10 on the two rotating plates 203 rotate to a state of mutual approach. The piston shaft driven by the hydraulic cylinder 8 on the support seat 7 pushes the other first mold 9 and the second mold 10 to gradually close the mold, and draw a new roll of aluminum alloy wire. This process can be repeated alternately.

[0045] In Example 2, based on Example 1, a third parting mold 14 is fixedly installed on one side of the first parting mold 9, and a fourth parting mold 15 is fixedly installed on one side of the second parting mold 10. The middle part of the opposite side of the third parting mold 14 and the fourth parting mold 15 is designed with a smooth slope. After the first parting mold 9 and the second parting mold 10 are closed, the slopes of the third parting mold 14 and the fourth parting mold 15 are spliced ​​together. The mold hole after the third parting mold 14 and the fourth parting mold 15 are closed corresponds to the mold hole after the first parting mold 9 and the second parting mold 10 are closed. When the production process technology and cost of the wire drawing die are low, and there is a gap in the mold hole after the first parting mold 9 and the second parting mold 10 are closed, the addition of the third parting mold 14 and the fourth parting mold 15 can further ensure the quality of aluminum alloy wire drawing and prevent the problem of protrusions on the wire drawing surface due to the gap in the mold hole.

[0046] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

4. The alloy drawing machine for aluminum alloy wire drawing according to claim 3, characterized in that, The side of the movable plate does not contact the inside of the chute, so that the inner wall of the chute will not affect the movement of the movable plate.

5. The alloy drawing machine for aluminum alloy wire drawing according to claim 2, characterized in that, Two support seats are fixedly installed on the top of the support platform. The two support seats are located inside the rotating plate, and two hydraulic cylinders are fixedly installed on the support seats. One end of the piston shaft of the two hydraulic cylinders faces the two sliding grooves inside the rotating plate. By setting the two hydraulic cylinders inside the rotating plate, the piston shafts are driven by the hydraulic cylinders to extend and push the moving plate and sliding shaft to move. This can control the first and second parting molds to move away from the central axis of the rotating plate. Furthermore, by driving the piston shafts to retract, the piston shafts of the hydraulic cylinders are located inside the rotating plate without affecting the rotation of the rotating plate.

6. The alloy drawing machine for aluminum alloy wire drawing according to claim 1, characterized in that, The first parting die has a mold groove on the side facing the second parting die, located on the upper and lower sides of the drawing die hole. The mold groove is a semi-circular groove. The second parting die has a protruding plate fixedly installed on the side facing the first parting die, located on the upper and lower sides of the die hole. The protruding plate is a semi-circular plate and is adapted to the mold groove. The two protruding plates are movably connected to the two mold grooves respectively. After the first parting die and the second parting die are spliced ​​to form a drawing die, the protruding plate is inserted into the inside of the mold groove. After the first parting die and the second parting die are closed, the integrity of the die hole is ensured, so as not to affect the drawing quality of the aluminum alloy wire.

7. The alloy drawing machine for aluminum alloy wire drawing according to claim 1, characterized in that, The top of the support platform is equipped with a limiting device located below the first and second parting molds. The limiting device includes a U-shaped slider movably mounted on the top of the support platform. Two linkage plates are fixedly mounted on one end of the U-shaped slider. The bottom ends of the two linkage plates extend to the bottom of the support platform and are fixedly connected to a positioning plate. A through groove is opened on the support platform to be movably connected to the linkage plates. A servo cylinder is fixedly mounted on the bottom of the support platform, located on one side of the positioning plate. The piston shaft of the servo cylinder is fixedly connected to the positioning plate. The servo cylinder drives the piston shaft to move the positioning plate, thereby moving the linkage plate and the U-shaped slider together. After the first and second parting molds are closed, the servo cylinder drives the U-shaped slider to move towards the wire drawing die, so that the two sides of the U-shaped slider are respectively attached to the outer sides of the first and second parting molds. With the limiting of the convex plate by the mold groove, the first and second parting molds are always in a stable closed state after the aluminum alloy wire passes through the mold hole of the wire drawing die.

8. The alloy drawing machine for aluminum alloy wire drawing according to claim 1, characterized in that, The cleaning device includes two support plates fixedly installed on the top of the support platform, with a rotatable roller between the two support plates. A cleaning motor that drives the roller to rotate is fixedly installed on one of the support plates. A cleaning brush is provided on the outer side of the roller. When the first and second dies on one of the two rotating plates are closed and wire drawing is performed, the other first and second dies on the two rotating plates face the cleaning brush. A piston shaft driven by another hydraulic cylinder on the support base pushes the first and second dies toward the cleaning brush. The cleaning motor drives the roller to rotate, and the cleaning brush temporarily cleans the die holes of the first and second dies, thereby improving the service life of the wire drawing die and effectively ensuring the quality of subsequent wire drawing.

9. The alloy drawing machine for aluminum alloy wire drawing according to claim 8, characterized in that, Another support plate is also fixedly installed with at least one nozzle facing the mold hole of the first or second mold. When temporarily cleaning the mold hole of the first or second mold, the high-pressure gas or cleaning solvent sprayed from the nozzle can be used in conjunction with the rotation of the cleaning brush to further improve the cleaning effect.

10. The alloy drawing machine for aluminum alloy wire drawing according to claim 1, characterized in that, A third parting mold is fixedly installed on one side of the first parting mold, and a fourth parting mold is fixedly installed on one side of the second parting mold. The middle part of the opposite side of the third and fourth parting molds is designed with a smooth slope. After the first and second parting molds are closed, the slopes of the third and fourth parting molds are spliced ​​together. The mold hole after the third and fourth parting molds are closed corresponds to the mold hole after the first and second parting molds are closed. When the production process technology and cost of the wire drawing die are low, and there is still a small gap in the mold hole after the first and second parting molds are closed, the addition of the third and fourth parting molds can further ensure the quality of aluminum alloy wire drawing and prevent the problem of protrusions on the wire drawing surface due to the gap in the mold hole.
