Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire production, in particular to a wire drawing die for an enameled wire. Background Art

[0002] There are two main methods for painting enameled wires, direct coating and resin extrusion. The direct coating method is to directly apply liquid paint on the metal wire, and then cure it into a film through high-temperature baking. The paint applicators in the direct coating method include the felt method and the mold method. The mold method is a method widely used in recent years. It can directly apply paint with higher viscosity and has a "self-centering" effect; the paint film thickness is well controllable, with few pinholes, a smooth and flat surface, good quality, fast routing speed, and high efficiency. However, the usual painting mold size is fixed, the mold cavity size cannot be adjusted, the wire size is diverse, and many fixed molds are required. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 The utility model provides a technical solution: a wire drawing die for an enameled wire, comprising a first die body 1 and a second die body 2, two pairs of the first die body 1 and the second die body 2 are spliced ​​together in an annular shape, a guide post 6 is fixedly arranged on one side of the first die body 1 and the second die body 2, a guide hole 7 is arranged on the adjacent sides of the first die body 1 and the second die body 2 close to the guide post 6, the guide holes 7 arranged on the first die body 1 and the second die body 2 and the extension directions of the guide posts 6 are perpendicular to each other, the guide posts 6 on the first die body 1 extend from the guide holes 7 on the second die body 2, and the guide posts 6 on the second die body 2 extend from the first die body 1, a side groove 8 is arranged on one side of the first mold body 1 and the second mold body 2, and an elastic ring member 13 is arranged in the side groove 8 to limit the position. The first mold body 1 and the second mold body 2 are both threadedly connected with an adjusting member 10 through a through threaded hole 9, and the adjusting member 10 can adjust the distance between the first mold body 1 and the second mold body 2 along the through threaded hole 9. The extension directions of the adjusting members 10 on the two different mold bodies are perpendicular to each other. The first mold body 1 and the second mold body 2 are both threadedly connected with a fastening screw 12 through a fastening threaded hole 11, and the fastening screw 12 limits and locks the adjusting member 10. Since the adjusting members 10 are perpendicular to each other, it is convenient to process the through threaded hole 9 on the mold body during adjustment, and the adjustment accuracy is improved at the same time.

[0023] The utility model can conveniently and quickly assemble the wire drawing die required for forming by setting the first die body 1 and the second die body 2 spliced ​​together in an annular shape, and can conveniently disassemble and replace a single die body when a problem occurs; by setting the adjusting member 10 and the fastening screw 12, the distance between the two pairs of the first die body 1 and the second die body 2 can be adjusted by controlling the stroke of the adjusting member 10 in the threaded hole 9, thereby adjusting the size of the entire wire drawing die. At the same time, due to the arrangement of the fastening screw 12, the position of the adjusting member 10 can be fixed after the adjustment of the adjusting member 10 is completed, effectively ensuring the stability of the wire drawing die after the size is adjusted.

[0024] Reference Figure 4 and 5 As shown, in this embodiment, the upper end surfaces of the first mold body 1 and the second mold body 2 are both threadedly connected with fasteners 3, gaskets 4 are provided through the fasteners 3, and sleeves 5 are sleeved on the fasteners 3. Through the provision of the fasteners 3 and sleeves 5, it is convenient to squeeze and fix a single first mold body 1 or a second mold body 2 on the mold frame through the gasket 4, which is convenient for subsequent maintenance and disassembly; through the provision of the sleeves 5, the stability after the extrusion installation can be effectively guaranteed.

[0025] Reference Figure 5 As shown, in this embodiment, the first mold body 1 and the second mold body 2 are both fixedly connected to the guide post 6 by a connecting sleeve 14, and the connecting sleeve 14 is threadedly connected to the guide post 6. The connecting sleeve 14 is provided to facilitate the installation and removal of the guide post 6. Since the guide post 6 is a wearing part during the application process, the threaded installation and fixing method is adopted to facilitate the daily removal and replacement of the guide post 6.

[0026] In this embodiment, the adjusting member 10 is a bolt, a screw, or a threaded rod with a notch at one end, and the diameter of the adjusting member 10 is greater than the diameter of the fastening screw 12 .

[0027] Reference Figure 2 As shown, in this embodiment, the elastic annular member 13 includes an annular spring or an elastic member integrally formed into a ring, and the diameter of the elastic annular member 13 is smaller than the groove width of the side groove 8. By setting the elastic annular member 13, after adjusting the spacing between the mold bodies by the adjusting member 10, the stability of the installation of the wire drawing die after assembly can be effectively guaranteed. At the same time, since the elastic annular member 13 is elastic, it can effectively adapt to the change of the size of the wire drawing die. By setting the limiting groove, the elastic annular member 13 can be stably limited in the groove, avoiding the situation that the elastic annular member 13 is offset during the use of the wire drawing die, thereby ensuring that the wire drawing die is not prone to eccentricity during use.
