Description

Technical Field

[0001] This utility model relates to the field of wire processing, specifically a novel magnesium alloy wire drawing device. Background Technology

[0002] Magnesium alloys have poor deformation capacity due to their close-packed hexagonal structure. Therefore, they often form a strong base texture during unidirectional drawing, which leads to brittle fracture of the wire. Moreover, existing drawing processes mostly imitate the preparation process of aluminum alloys: multiple intermediate annealing treatments are used, followed by gradual diameter reduction drawing using a drawing machine. The process is complex and has low production efficiency. Therefore, this application proposes a new magnesium alloy wire drawing device. Utility Model Content

[0003] The purpose of this invention is to provide a novel magnesium alloy wire drawing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel magnesium alloy wire drawing device, comprising an insulated box, wherein an alloy wire is threaded through the insulated box in a horizontal direction, and a first drawing die, a second drawing die, and a third drawing die are sequentially arranged in a horizontal direction inside the insulated box. The alloy wire enters from one side of the insulated box, passes through the drawing holes of the first drawing die, the second drawing die, and the third drawing die in sequence, and exits from the other side of the insulated box. The bottom ends of the first drawing die, the second drawing die, and the third drawing die are respectively fixedly connected to bases, and the bottom end of each base is respectively fixedly connected to several connecting rods. An installation block is fixedly installed on the bottom end of the inner wall of the insulated box, and several sliders are slidably installed on the surface of the installation block. The bottom ends of the connecting rods near the installation block are engaged and fixedly connected to the top ends of the sliders.

[0005] Preferably, the diameter of the drawing hole in the first drawing die is larger than the diameter of the drawing hole in the second drawing die, and the diameter of the drawing hole in the second drawing die is larger than the diameter of the drawing hole in the third drawing die.

[0006] Preferably, each of the connecting rods has a snap-fit ​​protrusion fixedly connected to its top end, and each base has a bottom mounting groove at its bottom end that engages with the snap-fit ​​protrusion.

[0007] Preferably, each of the connecting rods has a snap-fit ​​groove at its bottom end that engages with the snap-fit ​​protrusion.

[0008] Preferably, each of the sliders has a top fixing protrusion that engages with the locking groove of the connecting rod.

[0009] Preferably, the first drawing die and the third drawing die are respectively fixedly connected to guide arc blocks on one side close to each other, and the second drawing die is respectively fixedly connected to guide arc blocks on both sides.

[0010] Preferably, the top of the guide arc blocks of the first and third drawing dies and the bottom of the two guide arc blocks of the second drawing die are respectively set as arc-shaped cross-section structures.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] This invention introduces the alloy wire into the insulation box from one side, and then sequentially passes it through a first drawing die, a second drawing die, and a third drawing die with progressively smaller diameter holes. While undergoing multiple diameter-changing drawing processes directly within the insulation box, guide arc blocks are installed on the first, second, and third drawing dies. These guide arc blocks have an arc-shaped cross-section, allowing for adjustment of the spacing between adjacent first, second, and third drawing dies, as well as adjusting the height of the first, second, and third drawing dies through the installation of different numbers of connecting rods. This allows for adjustment of the angle at which the alloy wire is drawn between adjacent first, second, and third drawing dies. Through multiple drawing processes within the insulation box, the problem of strong unidirectional drawing surface texture can be improved, achieving texture optimization and enhancing the plasticity of the wire, which is of significant value for mass production.

[0016] Example 1

[0017] Please see Figure 1The illustration shows a novel magnesium alloy wire drawing device, comprising an insulated box 1. An alloy wire 2 is threaded through the insulated box 1 in a horizontal direction. Inside the insulated box 1, a first drawing die 3, a second drawing die 4, and a third drawing die 5 are arranged sequentially in a horizontal direction. The alloy wire 2 enters from one side of the insulated box 1, passes through the drawing holes of the first drawing die 3, the second drawing die 4, and the third drawing die 5, and exits from the other side of the insulated box 1. A base 6 is fixedly connected to the bottom of each of the first drawing die 3, the second drawing die 4, and the third drawing die 5, and several connecting rods 7 are fixedly connected to the bottom of each base 6. An installation block 9 is fixedly installed on the bottom of the inner wall of the insulated box 1, and several sliders 8 are slidably installed on the surface of the installation block 9. The bottom of the connecting rods 7 near the installation block 9 is engaged and fixed to the top of the sliders 8. A side door is hinged to one side of the insulated box 1 to facilitate operations inside the insulated box 1.

[0018] In this embodiment, the diameter of the drawing hole of the first drawing die 3 is larger than that of the second drawing die 4, and the diameter of the drawing hole of the second drawing die 4 is larger than that of the third drawing die 5. Each connecting rod 7 has a snap-fit ​​protrusion 10 fixedly connected to its top end, and each base 6 has a bottom mounting groove 12 that snaps into the snap-fit ​​protrusion 10 at its bottom end. Each connecting rod 7 has a snap-fit ​​groove 11 that snaps into the snap-fit ​​protrusion 10 at its bottom end. Each slider 8 has a top fixing protrusion 13 fixedly connected to its top end that snaps into the snap-fit ​​groove 11 of the connecting rod 7. The first drawing die 3 and the third drawing die 5 are respectively fixedly connected to guide arc blocks 14 on one side close to each other, and the second drawing die 4 has guide arc blocks 14 fixedly connected to both sides. The top ends of the guide arc blocks 14 of the first drawing die 3 and the third drawing die 5, as well as the bottom ends of the two guide arc blocks 14 of the second drawing die 4, are respectively set as arc-shaped cross-section structures.

[0019] Furthermore, the alloy wire 2 is introduced into the insulation box 1 from one side and passes sequentially through the first drawing die 3, the second drawing die 4, and the third drawing die 5, whose diameters decrease progressively. While multiple diameter-changing drawing processes are performed directly within the insulation box 1, guide arc blocks 14 are provided on the first drawing die 3, the second drawing die 4, and the third drawing die 5. These guide arc blocks 14 have an arc-shaped cross-section, which facilitates adjusting the spacing between adjacent first drawing dies 3, second drawing dies 4, and third drawing dies 5, and adjusting the height of the first drawing die 3, second drawing die 4, and third drawing die 5 through the installation of different numbers of connecting rods 7. This allows for adjustment of the angle at which the alloy wire 2 is drawn between adjacent first drawing dies 3, second drawing die 4, and third drawing die 5. Through multiple drawing processes within the insulation box 1, the problem of strong unidirectional drawing surface texture can be improved, achieving texture optimization and improving the plasticity of the wire, which is of significant value for mass production.
