Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing dies, in particular to a wire drawing die for a heat-resistant aluminum alloy conductor. Background Art

[0002] A wire drawing die is a tool that forces metal to pass through a die under external force during metal pressure processing, compresses the metal's cross-sectional area, and obtains the required cross-sectional shape and size. Wire drawing dies are widely used, such as high-precision wires used in electronic devices, radars, televisions, instruments, and aerospace, as well as commonly used tungsten wires, molybdenum wires, stainless steel wires, wire and cable wires, and various alloy wires. Diamond wire drawing dies use natural diamonds as raw materials, so they have extremely strong wear resistance and extremely high service life. The production process of wire drawing die inserts includes several process steps such as die pressing, die drawing, and turning. The wire drawing die passes the metal wire through the die, making it from coarse to fine, and gradually reaches the size people need. This special die is a wire drawing die. The core of the wire drawing die is generally made of natural diamonds and artificial diamonds (artificial diamonds include GE, PCD, synthetic materials, etc.); copper wire drawing dies belong to soft wire drawing dies, and there are also hard wire drawing dies, such as tungsten wire drawing, etc. The angle of the compression zone of the tungsten wire drawing die is relatively small, generally 12-14 degrees.

[0003] When using the existing wire drawing dies for heat-resistant aluminum alloy wires, the design of the die hole needs to determine the size and shape according to the requirements of the wire to ensure that the wire can be properly stretched and deformed during the wire drawing process. However, the size of the existing die hole is not easy to adjust. When drawing different aluminum alloys, due to different ductility, it is necessary to select a corresponding die hole. It is troublesome to replace the die hole of the existing wire drawing die, and the friction force during the wire drawing process is large, which is not conducive to the smooth progress of the wire drawing process.

[0013] (III) Beneficial effects

[0014] The utility model provides a wire drawing die for a heat-resistant aluminum alloy conductor, which has the following beneficial effects:

[0015] 1. The wire drawing die for heat-resistant aluminum alloy wire has the effect of facilitating the adjustment of the size of the die hole through the arrangement of the die body, the rotating shaft, the driven bevel gear, the first motor and the driving bevel gear. When in use, the staff selects a suitable die hole according to the ductility of the aluminum alloy, and rotates the suitable die hole to the bottom. During the adjustment process, the first motor is controlled to drive the driving bevel gear to rotate, and the driving bevel gear then drives the driven bevel gear. The driven bevel gear drives the die body to rotate in the rotating groove through the rotating shaft, so that the suitable die hole on the surface of the die body is rotated to the bottom of the mounting block. The aluminum alloy is stretched through the die hole to gradually become thinner, and the stretching of the aluminum alloy is completed. The device is highly practical and can quickly adjust the suitable die hole, thereby achieving the purpose of easy adjustment.

[0016] 2. The wire drawing die of the heat-resistant aluminum alloy wire has the effect of reducing friction during the drawing process by arranging the oil cavity, the ball groove, the ball and the oil groove. When in use, when the aluminum alloy wire is drawn through the die hole, when the aluminum alloy wire just enters the die hole, the surface of the aluminum alloy wire contacts the ball. As the aluminum alloy wire moves to the left, the ball is driven to roll in the ball groove. Since lubricant is injected into the oil cavity, an oil groove is provided on the surface of the ball. When the oil groove on the surface of the ball rolls into the oil cavity, the lubricant in the oil cavity enters the oil groove. As the oil groove rotates, the lubricant in the oil cavity is brought out, and the lubricant flows to the inlet of the die hole, so that the lubricant is stained on the surface of the aluminum alloy wire. By applying lubricant to the surface of the aluminum alloy wire, the friction during the drawing process is reduced, and the purpose of facilitating deformation during the wire drawing process is achieved.
