Description

Technical Field

[0001] This utility model belongs to the technical field of copper drawing equipment, and in particular relates to a wire guiding component for copper drawing equipment. Background Technology

[0002] Copper drawing refers to a process step in copper processing, specifically the "large drawing" stage in the stretching process of copper rods or wires. This is a common cold drawing process in metal processing, mainly used to process thicker copper rods into thinner copper wires using stretching equipment, while improving the mechanical properties and surface quality of the material.

[0003] During the large drawing process, the copper wire is supported and redirected by guide rollers. The wire-passing assembly is positioned between two guide rollers or between the guide rollers and the large drawing die, serving to guide the copper wire. During the large drawing process, the copper wire passes through several magnetic rings. The magnetic rings adsorb trace amounts of ferromagnetic impurities on the surface of the copper wire, protecting the equipment and improving product quality. Existing wire-passing assemblies and magnetic rings are separate, and the magnetic rings have a closed structure. This results in a complex design and makes disassembly and maintenance of the magnetic rings inconvenient. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a copper wire guide assembly that integrates a square magnetic eye and a magnetic rod design.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a wire-passing assembly for a large copper drawing device, comprising a positioning block, a bracket, a square magnetic eye, a magnetic rod fixing seat, and a magnetic rod body. The bracket is screwed and fixedly installed on the positioning block, the square magnetic eye is screwed and fixedly installed on the bracket, the square magnetic eye has a U-shaped wire-passing channel in the middle, the magnetic rod fixing seat is fixedly installed on the bracket, the magnetic rod body is fixedly installed on the magnetic rod fixing seat, and the area between the magnetic rod body and the bottom surface of the wire-passing channel is the wire-passing area.

[0006] Preferably, the central axis of the magnetic rod body is located at the center of the longitudinal height of the wire passage and is on the same horizontal plane.

[0007] Preferably, the inner walls on both sides of the cable passage are designed with a circular arc surface structure.

[0008] Preferably, an L-shaped plate is screwed onto the bracket, and a magnetic rod holder is fixedly mounted on the L-shaped plate.

[0009] Preferably, the two ends of the magnetic rod body extend 20mm-50mm beyond the inner and outer end faces of the magnetic rod fixing base.

[0010] Compared with the prior art, the advantages of this utility model are: the wire guiding assembly is combined with the square magnetic eye and the magnetic rod body. The square magnetic eye can play a guiding role in the wire guiding process, and has the advantage of simple design structure. In addition, the square magnetic eye and the magnetic rod body can comprehensively adsorb ferromagnetic impurities on the surface of the copper wire. The wire guiding channel of the magnetic rod body is set with a U-shaped structure, which allows for convenient maintenance, replacement or disassembly and cleaning of the square magnetic eye and the magnetic rod body without removing the copper wire from the drawing equipment during the large drawing process.

[0017] Figure 6 It is a 3D diagram of a square magnetic eye. Detailed Implementation

[0018] The present invention will now be described in detail with reference to specific embodiments: like Figures 1 to 6 The copper wire guiding assembly shown includes a positioning block 1, a bracket 2, a square magnetic eye 3, a magnetic rod fixing seat 5, and a magnetic rod body 6. The bracket 2 is screwed and fixedly installed on the positioning block 1, and the square magnetic eye 3 is screwed and fixedly installed on the bracket 2. The square magnetic eye 3 is a permanent magnet, and the square magnetic eye 3 has a U-shaped wire guiding channel 32 in the middle. The magnetic rod fixing seat 5 is fixedly installed on the bracket 2, and the magnetic rod body 6 is fixedly installed on the magnetic rod fixing seat 5. The area between the magnetic rod body 6 and the bottom surface of the wire guiding channel 32 is the wire guiding area.

[0019] The central axis of the magnetic rod body 6 is located at the center of the longitudinal height of the wire passage 32 and is on the same horizontal plane.

[0020] The inner walls on both sides of the wire passage 32 are set as arc surface structures 31. The width of the wire passage 32 is 1.1-1.3 times the width of the copper wire. When the copper wire contacts the inner wall of the wire passage 32, the arc surface structure 31 can reduce the contact area and thus reduce friction.

[0021] An L-shaped plate 4 is screwed onto the bracket 2, and a magnetic rod fixing seat 5 is fixedly installed on the L-shaped plate 4, which facilitates the disassembly and assembly of the magnetic rod fixing seat 5, thereby facilitating the cleaning and maintenance of the magnetic rod body 6.

[0022] The magnetic rod body 6 extends 25mm beyond the inner and outer end faces of the magnetic rod fixing base 5 at both ends. During maintenance, the combination of the magnetic rod fixing base 5 and the magnetic rod body 6 can be rotated 180° and then installed on the bracket 2. After both ends of the magnetic rod body 6 have been used, it can be disassembled and cleaned. The outer end face of the magnetic rod body 6 extends 10-15mm beyond the wire passage 32. The wire passage area formed between the magnetic rod body 6 and the bottom surface of the wire passage 32 is completely closed. The complete closure of the wire passage area does not refer to a closed structure, but rather that the square magnetic eye 3 and the magnetic rod body 6 can fully adsorb trace amounts of ferromagnetic impurities.

[0023] The positioning block 1 is screwed and fixedly installed on the sheet metal housing of the copper wire drawing equipment. During the large drawing process, the copper wire passes through the U-shaped wire passage 32. The magnetic rod body 6 is located above the copper wire. The square magnetic eye 3 and the magnetic rod body 6 work together to fully adsorb ferromagnetic impurities on the surface of the copper wire.
