Detailed Implementation

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example

[0021] Please see Figure 1-5 An adjustable cold drawing device for electroplated tungsten wire includes a main body 1, a rotating rod 2 rotatably connected inside the main body 1, an adjusting plate 3 on one side of the rotating rod 2, a ring of cold drawing holes 4 on the outer side of the adjusting plate 3, a bearing seat 5 in the middle part of the rotating rod 2, a fixing component on one side of the bearing seat 5, a ring of positioning holes 6 corresponding to the fixing component on one side of the adjusting plate 3, and protruding teeth 7 evenly arranged on the outer side of the adjusting plate 3.

[0022] A drive device 8 is provided on one side of the rotating disk. The drive end of the drive device 8 is connected to a drive tooth 9 corresponding to the convex tooth 7. A support base 10 is provided on one side of the rotating disk. An annular groove 11 is provided in the middle part of the rotating disk. An arc-shaped piece 12 corresponding to the annular groove 11 is opened on one side of the support base 10.

[0023] The fixing component includes a fixing block 13 disposed on one side of the bearing seat 5, and a rotating rod 2 passing through the fixing block 13 and connected to the adjusting plate 3. The fixing block 13 has notches on both sides, and through holes are provided on both sides of the notches. Positioning bolts 14 corresponding to positioning holes 6 are inserted into the through holes.

[0024] It should be noted that when performing cold drawing operation on electroplated tungsten wire, the tungsten wire can be inserted into the body 1 through the wire inlet 16 and inserted into the cold drawing hole 4 corresponding to the wire inlet 16. Then, the tungsten wire is discharged through the wire outlet 17. Finally, the tungsten wire can be pulled by the traction device, thereby realizing the cold drawing operation of electroplated tungsten wire.

[0025] In actual use, the diameter of the cold-drawn hole 4 needs to be adjusted according to the usage situation. At this time, the operator removes the positioning bolt 14 that passes through the positioning hole 6 and the through hole, and controls the drive device 8, drive gear 9 and convex gear 7 to cooperate to drive the rotating disk and rotating rod 2 to rotate, so that the required cold-drawn hole 4 is precisely aligned with the wire inlet 16. Then, the positioning bolt 14 is passed through the through hole and the positioning hole 6 again. At the same time, the positioning bolt 14 is threaded with a positioning nut, which can fix the fixing block 13 and the rotating disk again, which is convenient for subsequent cold drawing operations.

[0026] During the cold drawing process, the support base 10, the arc-shaped piece 12, and the annular groove 11 work together to provide horizontal support for the rotating disk without affecting its rotation, thereby increasing the stability and safety of the rotating disk during the cold drawing process and preventing the rotating disk from becoming loose.

[0027] The drive device 8 mainly consists of a housing and a servo motor. This technology is well known to those skilled in the art and will not be described in detail. There are four cold-drawn holes 4, each with different specifications. There are also four positioning holes. The positions of the cold-drawn holes 4 and the positioning holes are staggered and do not interfere with each other.

[0028] A reinforcing rib 15 is provided on the lower side of the support base 10 to increase the overall support effect of the support base 10.

[0029] The main body 1 has a wire inlet 16 and a wire outlet 17 on the front and rear sides, respectively, to facilitate cold drawing operations.

[0030] A lubricating oil outlet 18 is provided on one side of the main body 1. During the cold drawing process, a lubricating oil spraying structure can be added to the upper side of the main body 1 to increase the cold drawing effect. The lubricating oil after use can be discharged through the lubricating oil outlet 18.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
