Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire drawing ultra-precision machine technology, and in particular to a texture drawing and embedding mold in a wire drawing ultra-precision machine. Background Technology
[0002] Wire drawing dies are the "core tools" of ultra-precision wire drawing machines. They have die holes of specific shapes (such as round or irregular shapes) inside. When the metal billet passes through the die holes, it is subjected to compression and stretching, which reduces the cross-section, extends the length, and obtains the required dimensional accuracy and surface roughness.
[0003] Currently, in fields such as metal wire processing, it is often necessary to perform wire drawing on the surface of materials to obtain specific texture effects. This not only enhances the aesthetics of the product but may also improve certain properties. However, traditional wire drawing dies have some problems during use: after prolonged use, the texture forming part of the die is prone to wear, leading to a decrease in the precision and consistency of the wire drawing texture, which affects product quality. When it is necessary to change to a different wire drawing texture, the existing die often needs to be replaced as a whole, which is complicated and costly. Therefore, it is urgent to design a texture drawing and interlocking die for a wire drawing ultra-precision machine to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a texture drawing interlocking mold for ultra-precision wire drawing machines. Its advantages lie in the fact that when the texture forming surface wears down or the texture type is changed, only the entire mold needs to be disassembled and reassembled via the connecting components, and the texture interlocking ring can be replaced individually. This eliminates the need for a complete replacement, simplifying operation, significantly reducing mold replacement time and costs, and automatically correcting wire misalignment. This effectively solves the problem of unstable interlocking between the mold and the processed material, thus improving product quality.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The fitting mold body has its inner wall arranged in sequence as an inlet area, a lubrication area, a working area and an outlet area, and the fitting mold body is composed of a lower mold base and an upper mold base that are semi-circular.
[0008] Connecting components are used to reinforce the lower mold base and the upper mold base;
[0009] The textured interlocking ring is semi-circular. Both the lower mold base and the upper mold base have annular grooves for the textured interlocking ring to be inserted into their working areas. The inner diameter of the textured interlocking ring is the same as the inner diameter of the working area. The inner wall of the textured interlocking ring is set as a textured forming surface.
[0010] A fitting stabilizing component is disposed in the entrance area of the lower mold base and the upper mold base.
[0011] With the above technical solution, when the textured surface is worn or the texture type is changed, it is only necessary to disassemble and assemble the entire mold through the connecting components and replace the texture interlocking ring separately. There is no need to replace the whole mold, which is simple to operate and greatly reduces the mold replacement time and cost.
[0012] The present invention is further configured such that the connecting component includes connecting grooves opened on both sides of the bottom of the lower mold base and both sides of the top of the upper mold base, and a threaded hole penetrating the lower mold base and the upper mold base is opened at the middle of two adjacent connecting grooves, and a threaded post is threaded into the inner wall of the threaded hole.
[0013] The present invention is further configured such that a washer is fitted at the bottom of each of the screw posts, and a nut is screwed to the bottom end of each screw post.

[0015] The present invention is further configured such that the textured interlocking ring and the textured forming surface are made of hard alloy material, and the textured forming surface is coated with a wear-resistant coating.
[0016] The above technical solutions significantly improve wear resistance, extend mold life, and ensure the long-term precision and stability of wire drawing texture.
[0017] The present invention is further configured such that the inner wall of the annular groove is provided with a fitting groove, and the outer wall of the textured fitting ring is fixed with a fitting boss inserted into the fitting groove.

[0019] The present invention is further configured such that multiple positioning holes are provided at both ends of the top of the lower mold base, and positioning pins inserted into the positioning holes are fixed at both ends of the bottom of the upper mold base.
[0020] The above technical solutions enable precise alignment of the upper and lower mold bases, avoiding texture deviations caused by misalignment during splicing.
[0021] The present invention is further configured such that positioning grooves are provided at both ends of the top of one of the textured interlocking rings, and positioning plates inserted into the positioning grooves are fixed at both ends of the bottom of the other textured interlocking ring.
[0022] The above technical solutions ensure seamless connection between the upper and lower mold texture surfaces, avoiding texture breakage or misalignment defects caused by installation errors.
[0023] The present invention is further configured such that the fitting and stabilizing component is composed of an annular elastic clamping plate and an arc-shaped protrusion, and the arc-shaped protrusion is fixed to the inner wall of the elastic clamping plate, the elastic clamping plate is fixed to the inner wall of the entrance area, the cross-section of the elastic clamping plate is arc-shaped, and the inner wall of the arc-shaped protrusion is arc-shaped.

[0027] 2. In this utility model, the adjacent texture interlocking rings are engaged with the positioning plate through positioning grooves to ensure seamless connection of the upper and lower mold texture forming surfaces, avoiding texture breakage or misalignment defects caused by installation errors. Furthermore, the texture interlocking rings and texture forming surfaces are made of hard alloy material and coated with a wear-resistant coating, which significantly improves wear resistance, extends the service life of the mold, and ensures the accuracy and stability of the long-term wire drawing texture.

Detailed Implementation
[0038] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.
[0039] Reference Figures 1-7 This utility model provides a texture drawing and fitting mold for a wire drawing ultra-precision machine, comprising:
[0040] The fitting mold body has its inner wall arranged in sequence as an inlet area 5, a lubrication area 6, a working area 7 and an outlet area 8, and the fitting mold body is composed of a lower mold base 1 and an upper mold base 2 in a semi-circular shape.
[0041] The connecting component 3 is used to reinforce the lower mold base 1 and the upper mold base 2. The connecting component 3 includes connecting grooves 31 opened on both sides of the bottom of the lower mold base 1 and both sides of the top of the upper mold base 2. A threaded hole 32 penetrating the lower mold base 1 and the upper mold base 2 is opened in the middle of two adjacent connecting grooves 31. A threaded post 33 is threaded into the inner wall of the threaded hole 32. A washer 34 is fitted on the bottom of each threaded post 33, and a nut 35 is threaded into the bottom end of each threaded post 33.
[0042] The textured interlocking ring 10 is semi-circular. Both the lower mold base 1 and the upper mold base 2 have annular grooves 14 in their working areas 7 for the textured interlocking ring 10 to be inserted. The inner diameter of the textured interlocking ring 10 is the same as the inner diameter of the working area 7. The inner wall of the textured interlocking ring 10 is set as a textured forming surface 17. The textured interlocking ring 10 and the textured forming surface 17 are made of hard alloy material, and the textured forming surface 17 is coated with a wear-resistant coating. When the textured forming surface 17 is worn or the texture type is changed, it is only necessary to disassemble and assemble the entire mold through the connecting component 3 and replace the textured interlocking ring 10 separately. There is no need to replace the whole mold. The operation is simple and greatly reduces the mold replacement time and cost.
[0043] The fitting stabilizing component 4 is disposed in the entrance area 5 of the lower die holder 1 and the upper die holder 2. The fitting stabilizing component 4 consists of an annular elastic clamping plate 41 and an arc-shaped protrusion 42. The arc-shaped protrusion 42 is fixed to the inner wall of the elastic clamping plate 41, and the elastic clamping plate 41 is fixed to the inner wall of the entrance area 5. The cross-section of the elastic clamping plate 41 is arc-shaped, and the inner wall of the arc-shaped protrusion 42 is arc-shaped. The elastic clamping plate 41 and the arc-shaped protrusion 42 of the fitting stabilizing component 4 form a flexible guiding structure, which applies uniform radial pressure to the wire entering the die, automatically corrects the wire offset, effectively solves the problem of unstable fitting between the die and the processed material, and ensures that the material will not be displaced during the wire drawing process.
[0044] To achieve stable installation of the texture mating ring 10, refer to Figure 6 and Figure 7 The inner wall of the annular groove 14 is provided with a fitting groove 15, and the outer wall of the textured fitting ring 10 is fixed with a fitting boss 16 inserted into the fitting groove 15. The stable installation of the textured fitting ring 10 is achieved by the cooperation between the fitting boss 16 and the fitting groove 15.
[0045] To ensure precise alignment of the upper and lower mold bases, refer to Figure 3 and Figure 4 Multiple positioning holes 9 are provided at both ends of the top of the lower mold base 1, and positioning pins 12 inserted into the positioning holes 9 are fixed at both ends of the bottom of the upper mold base 2. The upper and lower mold bases are precisely aligned through the positioning holes 9 and the positioning pins 12 to avoid texture deviation caused by splicing misalignment.
[0046] To ensure a seamless connection between the two textured interlocking rings 10, refer to Figure 3 and Figure 4 One of the textured interlocking rings 10 has positioning grooves 11 at both ends of its top, and the other textured interlocking ring 10 has positioning plates 13 fixed at both ends of its bottom, which are inserted into the positioning grooves 11. The adjacent textured interlocking rings 10 are connected to the positioning plates 13 through the positioning grooves 11 to ensure seamless connection of the upper and lower mold texture forming surfaces 17, and avoid texture breakage or misalignment defects caused by installation errors.
[0047] Working principle: When in use, the metal wire first enters the entrance area 5 of the mold. Here, the fitting and stabilizing component 4 plays a role. The flexible guiding structure composed of the elastic clamping plate 41 and the arc-shaped protrusion 42 will apply uniform radial pressure to the wire, which can automatically correct any possible deviation of the wire and allow the wire to enter the subsequent area in a stable posture.
[0048] Next, the wire enters the lubrication zone 6, where the lubricant can be evenly applied to the surface of the wire, providing sufficient lubrication for the subsequent wire drawing process and reducing the frictional resistance between the wire and the die;
[0049] Subsequently, the wire enters the working area 7. The texture fitting ring 10 in the working area 7 is the key component for texture forming. Both the lower mold base 1 and the upper mold base 2 have annular grooves 14 in the working area 7 for the texture fitting ring 10 to be inserted. The inner diameter of the texture fitting ring 10 is the same as the inner diameter of the working area 7. When the wire passes through the texture fitting ring 10, the texture forming surface 17 on its inner wall will be squeezed to form the required texture on the surface of the metal wire. The texture fitting ring 10 is made of hard alloy material and the inner wall is coated with a wear-resistant coating, which can ensure the accuracy and stability of texture forming during long-term operation. At the same time, the fitting groove 15 on the inner wall of the annular groove 14 and the fitting boss 16 on the outer wall of the texture fitting ring 10 cooperate with each other to ensure that the texture fitting ring 10 will not be displaced during operation, thus ensuring the consistency of texture forming.
[0050] Finally, the textured wire exits from exit area 8.
[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
