Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper-clad steel wire technology, specifically a drawing die for producing copper-clad steel wire. Background Technology
[0002] Copper-clad steel refers to a composite wire in which copper is wrapped around steel wire, essentially a steel wire surrounded by a copper layer. It utilizes the skin effect of low-voltage, high-frequency signals, allowing them to travel along the surface in the high-frequency range. Therefore, as long as the copper layer thickness reaches a certain range, signals in a specific frequency band can be reliably transmitted. The copper acts as a conductor of weak electrical signals, while the steel wire provides support. During production, copper-clad steel wire requires drawing using a die to plastically deform the wire, reducing its diameter and extending its length to achieve the desired size and shape.
[0003] Currently, if there are impurities or dirt on the inner wall of the drawing die during use, they can easily adhere to the copper-clad steel wire during wire drawing, causing scratches or pits on the wire surface and affecting product quality. Disassembly and cleaning are usually required, which is too complicated. Therefore, a drawing die for producing copper-clad steel wire is needed. Utility Model Content
[0004] The purpose of this invention is to provide a drawing die for producing copper-clad steel wire, which solves the problems mentioned in the background art.
[0005] This application provides a drawing die for producing copper-clad steel wire, including a mounting frame. An electric push rod is fixedly inserted through the top of the mounting frame. A motor is fixedly connected to the end face of the output shaft of the electric push rod. A rod body is threadedly connected to the output shaft of the motor. A brush is fixedly connected to the outer wall of the rod body. A dust suction pipe is fixedly inserted through the bottom of the mounting frame. A mounting shell is fixedly connected to the bottom of the dust suction pipe. A suction fan is installed inside the mounting shell. Motors are installed on both outer walls of the mounting frame. A die body is fixedly connected between the output shafts of the two motors.
[0006] During use, when the copper-clad steel wire enters the entrance area of the die hole in the die body, the copper-clad steel wire begins to undergo compression deformation due to the gradually decreasing diameter of the die hole and the radial pressure exerted by the inner wall of the die body. This compression continues, causing the cross-sectional area of the copper-clad steel wire to decrease continuously and its diameter to gradually become thinner, thus completing the pulling of the copper-clad steel wire. When cleaning the die body is required, first ensure that there is no copper-clad steel wire on the die body, and then start the motor through the external power switch. The motor's output shaft can drive the die body to rotate, so that the smaller end of the die hole faces downward. The electric push rod pushes the rod into the die hole, and the motor's output shaft can drive the rod to rotate. When the rod rotates, it can drive the brush to rotate, which can quickly clean the die hole without disassembling the die body for cleaning. Furthermore, with the cooperation of the suction fan and the dust suction pipe, the cleaned impurities can be simultaneously sucked into the mounting shell and discharged into the collection box, further ensuring the cleaning effect and making it convenient and practical.
[0007] Optionally, the mold body has a mold hole, which is conical, with the larger end of the conical mold hole serving as the inlet and the smaller end serving as the outlet.
[0008] By adopting the above technical solution, when the copper-clad steel wire passes through the die hole, its diameter is reduced and its length is extended through plastic deformation, so as to obtain a tool with the required size and shape.
[0009] Optionally, the diameter of the rod is smaller than the diameter of the conical hole at the mold outlet, and the length of the brush is greater than the length of the conical hole at the mold inlet.
[0010] By adopting the above technical solution, it is beneficial for the brush to make full contact with the inner wall of the mold hole, and both the inlet and outlet of the mold hole can be cleaned.
[0011] Optionally, a reinforcing block is fixedly fitted on the outside of the output shaft of the motor, and a bolt is threaded through the reinforcing block and threadedly connected to the mold body.
[0012] By adopting the above technical solution, the contact area between the motor output shaft and the mold body can be increased under the action of the reinforcing block and bolts, thereby improving the stability of the installation.
[0013] Optionally, the output shafts of the two motors rotate synchronously in the same direction.
[0014] By adopting the above technical solution, it is beneficial for the normal flipping of the mold body.
[0015] Optionally, a collection box is provided below the mounting housing.
[0016] By adopting the above technical solution, the collection box can collect clean impurities.
[0017] Optionally, the bottom end of the mounting housing is provided with an opening.
[0018] By adopting the above technical solution, the impurities sucked in by the suction pipe will enter the interior of the mounting shell and be discharged into the collection box through the opening at the bottom of the mounting shell. The opening is also conducive to the normal use and heat dissipation of the suction fan.
[0019] Optionally, the brush is a soft nylon brush.
[0020] By adopting the above technical solution, the brush can be bent and deformed inside the die hole. The bending and deformation further increases the contact area between the brush and the inner wall of the die hole, improving the cleaning effect. At the same time, it increases the wear resistance of the brush and extends its service life.
[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0022] The technical solution of this application uses the output shaft of the motor to drive the mold body to rotate, so that the smaller end of the mold hole cone faces downward. The electric push rod pushes the rod into the mold hole, and the output shaft of the motor can drive the rod to rotate. When the rod rotates, it can drive the brush to rotate, which can quickly clean the mold hole without disassembling the mold body for cleaning. In addition, with the cooperation of the suction fan and the dust suction pipe, the cleaning impurities can be quickly sucked into the mounting shell and discharged into the collection box, further ensuring the cleaning effect and making it convenient and practical.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a drawing die for producing copper-clad steel wire, including a mounting frame 1, an electric push rod 3 fixedly inserted at the top of the mounting frame 1, a motor 2 fixedly connected to the end face of the output shaft of the electric push rod 3, a rod body 13 threadedly connected to the output shaft of the motor 2, a brush 14 fixedly connected to the outer wall of the rod body 13, a dust suction pipe 5 fixedly inserted at the bottom of the mounting frame 1, a mounting shell 6 fixedly connected to the bottom of the dust suction pipe 5, a suction fan 12 installed inside the mounting shell 6, motors 8 installed on both outer walls of the mounting frame 1, and a die body 11 fixedly connected between the output shafts of the two motors 8.
[0030] In the technical solution of this utility model, such as Figure 2 As shown, the mold body 11 has a mold hole 4, which is conical. The larger end of the conical hole 4 is the inlet, and the smaller end is the outlet. When the copper-clad steel wire passes through the mold hole 4, its diameter decreases and its length extends through plastic deformation to obtain a tool of the required size and shape.
[0031] In the technical solution of this utility model, such as Figure 1 As shown, the diameter of the rod 13 is smaller than the diameter of the cone hole at the outlet end of the die hole 4, and the length of the brush 14 is greater than the length of the cone hole at the inlet end of the die hole 4; this facilitates full contact between the brush 14 and the inner wall of the die hole 5, and enables cleaning of both the inlet and outlet of the die hole 4.
[0032] In the technical solution of this utility model, such as Figure 1 As shown, a reinforcing block 9 is fixedly sleeved on the outside of the output shaft of the motor 8, and a bolt 10 is threaded through the reinforcing block 9. The bolt 10 is threadedly connected to the mold body 11. Under the action of the reinforcing block 9 and the bolt 10, the contact area between the output shaft of the motor 8 and the mold body 11 can be increased, thereby improving the stability of the installation.
[0033] In the technical solution of this utility model, such as Figure 2 As shown, the output shafts of the two motors 8 rotate synchronously in the same direction, which is beneficial for the normal flipping of the mold body 11.
[0034] In the technical solution of this utility model, such as Figure 1 As shown, a collection box 7 is provided below the mounting shell 6; the collection box 7 can be used to collect clean impurities.
[0035] In the technical solution of this utility model, such as Figure 2 As shown, the bottom of the mounting housing 6 has an opening; impurities sucked in by the suction pipe 5 will enter the interior of the mounting housing 6 and be discharged into the collection box 7 through the opening at the bottom of the mounting housing 6. The opening is also conducive to the normal use and heat dissipation of the suction fan 12.
[0036] In the technical solution of this utility model, not shown, the brush 14 is a fine and soft nylon brush; the brush 14 can be bent and deformed inside the die hole 4, and the bending and deformation further increases the contact surface between the brush 14 and the inner wall of the die hole 4, improving the cleaning effect, while also increasing the wear resistance of the brush 14 and extending its service life.
[0037] In use, when the copper-clad steel wire enters the entrance area of the die hole 4 of the die body 11, the copper-clad steel wire is subjected to radial pressure from the inner wall of the die body 11 as the diameter of the die hole 4 gradually decreases, causing compression deformation. This compression continues, causing the cross-sectional area of the copper-clad steel wire to decrease continuously and the diameter to gradually become thinner, thus completing the pulling of the copper-clad steel wire. When it is necessary to clean the die body 11, first ensure that there is no copper-clad steel wire on the die body 11, and then start the motor 8 through the external power switch. The output shaft of the motor 8 can drive the die body 11 to rotate, so that the smaller end of the die hole 4 faces down. The electric push rod 3 pushes the rod 13 into the die hole 4. The output shaft of the motor 2 can drive the rod 13 to rotate. When the rod 13 rotates, it can drive the brush 14 to rotate, which can quickly clean the die hole 4 without disassembling the die body 11 for cleaning. In addition, with the cooperation of the suction fan 12 and the dust suction pipe 5, the cleaned impurities can be simultaneously sucked into the mounting shell 6 and discharged into the collection box 7, further ensuring the cleaning effect and making it convenient and practical.
[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
