Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a cold drawing machine for processing cables. Background Technology

[0002] The cold drawing machine for cable production is a core piece of equipment in metal wire processing. It is mainly used to draw metal rods such as copper and aluminum into wires of different specifications through cold plastic deformation to meet the dimensional accuracy and mechanical performance requirements of cable conductors. This equipment adopts a multi-pass continuous drawing process, using cemented carbide or polycrystalline diamond dies to progressively reduce the diameter of the metal wire, while improving its strength, ductility, and conductivity.

[0003] A search revealed that patent CN219805135U discloses a cold drawing machine for processing cables. This machine uses a feeding roller to feed the cable, which passes through a die hole and is then cold-drawn by a cold drawing plate. A rotating extrusion plate further compresses the cable, enhancing the cold drawing effect. An adjusting plate slides along a lead screw, adjusting the position and height of the cold drawing plate to allow for cold drawing of cables through dies of different diameters, thus improving the cold drawing efficiency. Although this cold drawing machine has multiple dies of different diameters, if a die wears out and needs replacement, the entire cold drawing plate must be replaced. Since cold drawing dies are typically made of tungsten carbide, replacing the entire plate results in material waste. Furthermore, the device lacks the function of removing and cleaning the oxide layer on the surface of the copper wires in the cable. Dust on the copper wire surface increases the wear rate of the die holes, thus requiring further improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cold drawing machine for processing cables.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cold drawing machine for processing cables, comprising a cleaning box, a lubrication box fixed to the outer wall of the cleaning box, and lubricating oil provided at the bottom of the lubrication box; an inlet and a first outlet are respectively opened on both sides of the cleaning box, the first outlet being located near the lubrication box; two grinding wheels are rotatably connected inside the cleaning box near the inlet; two symmetrical cleaning components are fixed inside the cleaning box near the first outlet; a second outlet is opened on the side of the lubrication box away from the cleaning box; a vertical plate is fixed inside the lubrication box near the second outlet; a through hole is opened in the middle of the vertical plate, and a detachable mold assembly is fixed inside the through hole.

[0006] Furthermore, both grinding wheels have a concave arc surface design in the middle, and the two grinding wheels are staggered vertically. Two motors that drive the grinding wheels to rotate are fixed on the outer wall of the cleaning box.

[0007] Furthermore, the cleaning assembly includes a fixing plate horizontally fixed inside the cleaning box, and springs are fixed to adjacent sides of the fixing plates of the two cleaning assemblies. A movable plate is fixed to the other end of the spring, and a cleaning cotton is fixed to the side of the movable plate away from the spring.

[0008] Furthermore, two first guide wheels are rotatably connected to the top of the inside of the lubrication tank and near the first discharge port, and two second guide wheels are rotatably connected to the bottom of the inside of the lubrication tank and below the two first guide wheels, with the two second guide wheels located below the lubricating oil level.

[0009] Furthermore, the mold assembly includes a through-hole mold head, with a mold hole in the center of the mold head.

[0010] Furthermore, a mounting plate is fixed to the side of the mold head near the cleaning box, and a connection hole is opened on the side of the mounting plate.

[0012] 1. In use, this utility model is a cold drawing machine for processing cables, which is equipped with a cleaning box, a lubrication box, a first guide wheel, a second guide wheel, a vertical plate and a mold assembly. Copper wires are cold drawn by passing through the mold holes of the mold assembly. When the mold holes of the mold assembly are severely worn, the mold assembly can be disassembled and replaced separately, thereby reducing material waste. Furthermore, for cold drawing copper wires of different diameters, mold assemblies with different mold holes can be replaced, making the cold drawing machine more flexible and convenient to use.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a cold drawing machine for processing cables is disclosed, comprising a cleaning box 1, a lubrication box 2 fixed to the outer wall of the cleaning box 1, and lubricating oil provided at the bottom of the lubrication box 2. The cleaning box 1 has an inlet 101 and a first outlet 102 on its two sides, respectively. The first outlet 102 is located on the side closer to the lubrication box 2. Two grinding wheels 3 are rotatably connected inside the cleaning box 1 near the inlet 101. Two symmetrical cleaning components 4 are fixed inside the cleaning box 1 near the first outlet 102. The lubrication box 2 has a second outlet 21 on the side away from the cleaning box 1. A vertical plate 7 is fixed inside the lubrication box 2 near the second outlet 21. A through hole 71 is opened in the middle of the vertical plate 7, and a detachable mold assembly 8 is fixed inside the through hole 71.

[0023] Both grinding wheels 3 have a concave arc design in the middle, and the two grinding wheels 3 are staggered vertically. Two motors that drive the grinding wheels 3 to rotate are fixed on the outer wall of the cleaning box 1.

[0024] In this embodiment, two motors drive two grinding wheels 3 to rotate respectively. The copper wire entering from the feed port 101 passes between the two grinding wheels 3, and the surface of the copper wire contacts the concave surface of the grinding wheel 3. The rotation direction of the grinding wheel 3 is opposite to the movement direction of the copper wire. During the movement of the copper wire, the oxide layer on the surface of the copper wire can be ground off by the grinding wheel 3.

[0025] The cleaning component 4 includes a fixing plate 41 that is horizontally fixed inside the cleaning box 1. Springs 42 are fixed on adjacent sides of the fixing plates 41 of the two cleaning components 4. A movable plate is fixed to the other end of the spring 42, and a cleaning cotton 43 is fixed on the side of the movable plate away from the spring 42.

[0026] In this embodiment, the cleaning cotton 43 and the movable plate are detachably connected, specifically by screw fixing, so the cleaning cotton 43 can be removed and replaced. When the steel wire, after being polished by the polishing wheel 3, passes between the two cleaning cottons 43, under the squeezing force of the spring 42, the two cleaning cottons 43 squeeze and wipe away the dust and impurities on the surface of the steel wire.

[0027] Two first guide wheels 5 are rotatably connected to the top of the inside of the lubrication tank 2 and near the first discharge port 102. Two second guide wheels 6 are rotatably connected to the bottom of the inside of the lubrication tank 2 and below the two first guide wheels 5. The two second guide wheels 6 are located below the lubricating oil level.

[0028] The copper wire drawn from the first discharge port 102 first passes over the upper first guide wheel 5, then passes over the two lower second guide wheels 6, and finally passes over the other upper first guide wheel 5, so that the copper wire can be immersed in lubricating oil, which is beneficial to the cold drawing process.

[0029] The mold assembly 8 includes a mold head 81 with a through hole 71, and a mold hole 82 is provided in the middle of the mold head 81.

[0030] A mounting plate 83 is fixed to the side of the mold head 81 near the cleaning box 1. A connection hole 84 is opened on the side of the mounting plate 83. A bolt 9 is fixed to the vertical plate 7 near the connection hole 84. The bolt 9 passes through the connection hole 84 and is rotatably connected to the surface of the bolt 9.

[0031] Since the mounting plate 83 on the mold head 81 is fixed to the vertical plate 7 by bolts 9, the entire mold assembly 8 can be disassembled and replaced. However, the mold assembly 8 is smaller in size and less material is wasted when disassembling and replacing it.

[0032] Working principle: Copper wire according to Figure 2 In the cold drawing process, the movement of the copper wire relies on external unwinding and rewinding mechanisms. During the wire's movement, two grinding wheels 3 first polish the surface of the copper wire to remove the oxide layer. Then, two cleaning cotton balls 43 wipe the surface of the copper wire. Afterward, the copper wire enters the bottom of the lubrication box 2 for immersion. The immersed copper wire then passes through the die hole 82 in the middle of the die head 81, achieving cold drawing. During use, the wear of the die hole 82 in the middle of the die head 81 is slower, resulting in a longer service life for the die assembly 8.

[0033] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
