AI Technical Summary
During the drawing process of stainless steel wire, the temperature rises due to the conversion of the main deformation work and the additional deformation work into heat. Uneven chemical composition or the presence of inclusions and pore defects lead to stress concentration, resulting in wire breakage.
A spraying mechanism is set in the entrance area of the wire drawing die. The stainless steel wire and the die are cooled down through the annular spray main pipe and spray branch pipe. Grooves, horizontal through holes and vertical through holes are set on the die body to enhance the heat dissipation effect.
This effectively avoids the temperature rise of the stainless steel wire, prevents wire breakage, and improves the stability and efficiency of the drawing process.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire drawing die technology, specifically to a high-efficiency wire drawing die for stainless steel wire. Background Technology
[0002] This generally refers to various dies for drawing metal wires, as well as dies for drawing optical fibers. All drawing dies have a hole of a specific shape in the center—round, square, octagonal, or other special shapes. As the metal is drawn through the die hole, its size decreases, and even its shape changes. For drawing soft metals (such as gold and silver), a steel die is sufficient; a steel die can have multiple holes of different diameters.
[0003] During the drawing process of stainless steel wire, although the wire is cold-drawn at room temperature, most of the main deformation work and additional deformation work consumed in the drawing will be converted into heat, causing the temperature to rise. If the chemical composition of stainless steel is uneven, or if there are inclusions, pores or other defects in the production process, these will cause stress concentration in the material during the stretching process, eventually leading to wire breakage. Utility Model Content
[0004] In view of the problems existing in the high-efficiency drawing dies for stainless steel wire, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a high-efficiency drawing die for stainless steel wire, which solves the problem that during the drawing process of stainless steel wire, although the wire is cold-drawn at room temperature, most of the main deformation work and additional deformation work consumed in the drawing will be converted into heat, resulting in a rise in temperature. If the chemical composition of stainless steel is uneven, or if there are inclusions, pores or other defects in the production process, these will all lead to stress concentration in the material during the stretching process, ultimately resulting in wire breakage.
[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:
[0007] A high-efficiency stainless steel wire drawing die includes a die body. The inlet end of the die body is equipped with a spraying mechanism. The spraying mechanism sprays water from the inlet area of the die body into the inner cavity of the die body. The spraying mechanism can not only cool the stainless steel wire passing through the die body, but also cool the die body itself.
[0008] As a preferred embodiment of the high-efficiency stainless steel wire drawing die of this utility model, the die body has, from left to right, an inlet area, a wire feeding area, a compression area, a sizing area and an outlet area.
[0009] As a preferred embodiment of the high-efficiency stainless steel wire drawing die of the present invention, the spraying mechanism includes an annular spraying main pipe installed at the inlet end of the die body, the annular spraying main pipe having a water inlet interface, and water outlets being provided at equal intervals on the inner wall of the annular spraying main pipe, the end of the water outlet being threadedly connected to a spraying branch pipe.
[0010] As a preferred embodiment of the high-efficiency stainless steel wire drawing die of this utility model, wherein: an installation block is welded on the outer wall of the annular spray main pipe, and internal threaded holes are provided at corresponding positions of the installation block and the inlet end of the die body, and the installation block and the die body are fixed together by bolts.
[0011] As a preferred embodiment of the high-efficiency stainless steel wire drawing die of the present invention, wherein: the die body is provided with grooves and vertical through holes that connect the grooves at equal intervals, and the body is provided with horizontal through holes that connect the vertical through holes.
[0012] In a preferred embodiment of the high-efficiency stainless steel wire drawing die of this utility model, the groove is connected to the wire inlet area.
[0013] Compared with existing technologies:
[0014] 1. By setting a spray mechanism at the entrance area of the mold body, water will enter the entrance area and pass through the stainless steel wires in the mold body and the inner wall of the wire inlet area due to the gap between the stainless steel wires entering the mold body and the inner wall of the wire inlet area. This will dissipate heat from the mold body and the stainless steel wires, effectively preventing wire breakage caused by the temperature rise of the stainless steel wires.
[0015] 2. By setting grooves, horizontal through holes and vertical through holes on the mold body, water enters the grooves and then enters the vertical and horizontal through holes, thereby further enhancing the heat dissipation effect on the mold body. Attached Figure Description

[0020] In the diagram: mold body 1, inlet area 11, inlet line area 12, compression area 13, sizing area 14, outlet area 15, groove 16, horizontal through hole 18, vertical through hole 19, annular spray main pipe 2, water inlet interface 21, mounting block 22, water outlet 23, spray branch pipe 3. Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0022] Example 1:
[0023] This utility model provides a high-efficiency stainless steel wire drawing die. Please refer to [link / reference]. Figure 1-2 The mold body 1 includes an inlet area 11, a wire feeding area 12, a compression area 13, a sizing area 14, and an outlet area 15, which are arranged from left to right. The inlet end of the mold body 1 is provided with a spraying mechanism. The spraying mechanism sprays water from the inlet area 11 of the mold body 1 into the inner cavity of the mold body 1. The spraying mechanism can not only cool the stainless steel wire passing through the mold body 1, but also cool the mold body 1.
[0024] The spraying mechanism includes an annular spraying main pipe 2 installed at the inlet end of the mold body 1. Specifically, an installation block 22 is welded to the outer wall of the annular spraying main pipe 2. The installation block 22 and the corresponding position of the inlet end of the mold body 1 are provided with internal threaded holes. The installation block 22 and the mold body 1 are fixed together by bolts. The annular spraying main pipe 2 has a water inlet interface 21. The water inlet interface 21 can be connected to a faucet through a conduit, or the water inlet interface 2 can be connected to the output end of a water pump through a conduit. Water is pumped into the spraying main pipe 2 by the water pump. Water outlets 23 are arranged at equal intervals on the inner wall of the annular spraying main pipe 2. The end of the water outlet 23 is threadedly connected to a spraying branch pipe 3. All spraying branch pipes 3 spray water into the inner cavity of the mold body 1. Since there is a gap between the stainless steel wire entering the mold body 1 and the inner wall of the wire inlet area 12, water will enter the wire inlet area 12 and pass through the stainless steel wire of the mold body 1, thereby dissipating heat from the mold body 1 and the stainless steel wire.
[0025] In practical use, the stainless steel wire passes through the inlet area 11, the wire inlet area 12, the compression area 13, the sizing area 14 and the outlet area 15 of the mold body 1 in sequence; at this time, the water in the annular spray main pipe 2 is sprayed out through the spray branch pipe 3 to the initial section of the wire inlet area 12 and the compression area 13 to dissipate heat from the mold body 1 and the stainless steel wire, thereby preventing the stainless steel wire from getting too hot.
[0026] Example 2:
[0027] See attached document Figure 3-4Unlike Embodiment 1, the mold body 1 has grooves 16 and vertical through holes 19 that connect the grooves 16 at equal intervals. The diameter of the grooves 16 is larger than the diameter of the vertical through holes 19, so that more water can enter the grooves 16. The body 1 also has horizontal through holes 18 that connect the vertical through holes 19. The grooves 16 connect to the wire inlet area 12.
[0028] In practical use, the stainless steel wire passes through the inlet area 11, the wire inlet area 12, the compression area 13, the sizing area 14 and the outlet area 15 of the mold body 1 in sequence; at this time, the water in the annular spray main pipe 2 is sprayed out through the spray branch pipe 3 to the initial section of the wire inlet area 12 and the compression area 13 to dissipate heat from the mold body 1 and the stainless steel wire, thereby preventing the stainless steel wire from getting too hot.
[0029] Water enters the groove 16 and then the vertical through hole 19 and the horizontal through hole 18, thereby further enhancing the heat dissipation effect on the mold body 1.
[0030] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
