Abstract
Description
Technical Field
[0001] This utility model relates to the field of tungsten wire drawing technology, and in particular to a combined wire drawing die base structure. Background Technology
[0002] Tungsten wire drawing equipment is used to draw coarse tungsten wires into fine tungsten wires through the holes of a drawing die. The tungsten wire first passes through a graphite emulsion, coating its surface with the emulsion before entering a heating zone. The heating zone dries the graphite emulsion, causing graphite powder to adhere to the surface of the tungsten wire. Simultaneously, the heating zone preheats the tungsten wire, which then passes through the drawing die. The drawing die holder has several die limiting grooves, and each drawing die is installed within one of these grooves, making die replacement very convenient. However, because the drawing die holder is subjected to pressure during use and requires heating during the drawing process, long-term use can easily lead to wear of the die limiting grooves, thus affecting accuracy. Since existing drawing die holders are all one-piece units, if any die limiting groove is damaged, the entire unit needs to be replaced, resulting in high maintenance costs. Furthermore, during the drawing process, metal shavings and graphite powder can enter the die positioning grooves, making cleaning inconvenient. Utility Model Content
[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a combined wire drawing die holder structure that is easy to maintain, low in cost, and easier to clean.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A combined wire drawing die base structure is disclosed. The top surface of the wire drawing die base is provided with several parallel wire feeding grooves. A die limiting groove is provided at the corresponding position of the top surface of the wire drawing die base and the wire feeding grooves. The wire drawing die base includes several die base bodies arranged side by side and positioning components for connecting the die base bodies. The die base bodies are cuboid in shape. Wire feeding notches are provided on both sides of the upper end of the die base bodies. Arc-shaped grooves are provided at the wire feeding notches on both sides of the die base bodies. The sides of any two adjacent die base bodies abut against each other. The wire feeding notches on two adjacent die base bodies combine to form the wire feeding grooves, and the arc-shaped grooves on two adjacent die base bodies combine to form the die limiting grooves.
[0006] Multiple die holders are connected in a row by connectors. The die limiting groove is used to install the wire drawing die. The tungsten wire passes through the wire drawing die from the wire inlet groove. When any die holder is damaged, only the damaged die holder needs to be replaced, which greatly reduces maintenance costs. When it is necessary to clean metal shavings and graphite powder, each die holder can be separated for better cleaning.
[0007] Preferably, the lower end of the mold base body is provided with a connecting through hole that extends through both sides. The positioning component is configured as a lead screw, which passes through the connecting through holes on all the mold base bodies in sequence. Both ends of the lead screw are provided with locking nuts. After the lead screw passes through the connecting through holes, all the mold base bodies are connected together. Disassembly can be achieved by loosening the locking nuts.
[0008] Preferably, the arc-shaped grooves on both sides of the mold base body are staggered and symmetrically distributed about the center, with any two adjacent mold base bodies being mirror images of each other. The staggered distribution of the arc-shaped grooves reduces the width dimension of the mold base body, making the entire structure more compact and the heating more uniform.
[0009] Preferably, the top surface of the wire feed groove is provided with relief grooves at both ends of the mold limiting groove. The relief grooves facilitate the better insertion of the wire drawing die into the mold limiting groove by fingers or tools (clamps), or make it easier to remove the die from the mold limiting groove.
[0010] Preferably, the die holder body is made of cast iron, and the bottom surface of the die holder body has a cavity for mounting a heating component. The cavity is used to mount the heating component to heat the wire drawing die holder.
[0011] Therefore, this utility model has the following beneficial effects: (1) The number of mold base bodies can be selected according to actual needs, making it more flexible to use; (2) When the mold base body is damaged, it can be replaced separately, reducing maintenance costs; (3) When cleaning graphite powder and metal shavings, the mold base body can be completely disassembled, making cleaning more convenient.

[0016] To make the technical problem to be solved, the technical solution, and the beneficial technical effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model.
[0017] It should be understood that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the number of technical features indicated. Features specified as "first" or "second" may expressly or implicitly indicate that at least one of those features is included.
[0018] like Figures 1-3 The diagram illustrates a combined wire drawing die holder structure. The top surface of the wire drawing die holder 1 has several parallel wire feeding grooves 100. A die limiting groove 101 is provided at the corresponding location on the top surface of the wire drawing die holder and the wire feeding grooves 100. The wire drawing die holder 11 includes several die holder bodies 10 arranged side-by-side and positioning members 2 for connecting the die holder bodies 10. The die holder bodies 10 have a cuboid structure. Wire feeding notches 100a are provided on both sides of the upper end of the die holder body 10. Arc-shaped grooves 101a are provided at the wire feeding notches 100a on both sides of the die holder body 10. The sides of any adjacent die holder bodies 10 abut against each other. The wire feeding notches 100a on two adjacent die holder bodies 10 combine to form the wire feeding groove 100, and the arc-shaped grooves 101a on two adjacent die holder bodies 10 combine to form the die limiting groove 101. Relief grooves 103 are provided at both ends of the die limiting groove 101 on the top surface of the wire feeding groove 100.
[0019] The lower end of the mold base body 10 is provided with a connecting through hole 102 that extends through both sides. The positioning element 2 is configured as a lead screw, which passes through all the connecting through holes 102 on the mold base body 10 in sequence. Both ends of the lead screw are provided with locking nuts 3. The mold base body 10 is made of cast iron, and the bottom surface of the mold base body 10 is provided with a cavity 104 for installing the heating component.
[0020] The arc-shaped grooves 101a on both sides of the die holder body 10 are staggered and symmetrically distributed about the center, and any two adjacent die holder bodies 10 are mirror images of each other. That is, when the die holder body is rotated 180° around the center of the top surface, it completely overlaps with the original structure. Therefore, all die holder bodies have the same structure, which allows the width of the die holder body to be designed to be smaller, the width of the entire wire drawing die holder to be smaller, and the overall structure to be more compact.
[0021] Referring to the accompanying drawings, the principle of this utility model is as follows: Figure 4 As shown, a drawing die base 10 is arranged in a row and connected by a lead screw and a locking nut to form a drawing die base 1. The drawing die base has nine wire inlet grooves and nine die limiting grooves. In use, a drawing die 4 is installed in each die limiting groove, and the tungsten wire 5 passes through each drawing die in a corresponding manner. A heating component is installed at the bottom of the cavity to heat the die base assembly and the drawing die during the drawing process. If any one of the die base bodies is damaged, it can be replaced individually, resulting in lower maintenance costs.
[0022] In the description of this utility model, it should be understood that the directions or positional relationships indicated by up, down, left, right, inner end, outer end, one end, and the other end are based on the orientation or positional relationships shown in the accompanying drawings. They are only for the purpose of more clearly describing the technical solution of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as a limitation of this utility model.
[0023] Although specific embodiments of the present invention are described in detail herein, they are given for illustrative purposes only and should not be construed as limiting the scope of the present invention. Various substitutions, alterations, and modifications may be conceived without departing from the spirit and scope of the present invention.
