A production process of brass wire

Abstract

The production process of a brass wire of the present invention belongs to the field of copper wire processing, and its steps are as follows: Step 1, raw material smelting, step 2, wire drawing, (1) move the copper rod of Φ12mm after the above-mentioned winding up to a place (2) The copper rod after paying off is drawn to the giant wire drawing machine for wire drawing, and the drawing pass is allocated as: Φ12mm‑ Φ9.5mm‑Φ8.5mm‑Φ8.2mm‑Φ8.0mm‑Φ7.5mm; step 3, packing after wire drawing is completed. This technical solution is not only simple in process and easy to control, but also has good surface quality of wire drawing.

Description

technical field [0001] The invention relates to the field of copper wire processing, in particular to a production process of brass wire. Background technique [0002] Copper alloy wires usually use butter to lubricate the drawing wheel during the wire drawing process, but this method causes the butter to solidify due to the high temperature during the wire drawing process, which affects the drawing surface quality of the copper wire and the dimensional accuracy of the wire drawing, and a lot of smoke and dust is diffused In the workshop, it affects the workshop environment. In addition, the existing wire drawing process has many complicated steps, and some of them are drawn through a water tank wire drawing machine.

[0002] Copper alloy wires usually use butter to lubricate the drawing wheel during the wire drawing process, but this method causes the butter to solidify due to the high temperature during the wire drawing process, which affects the drawing surface quality of the copper wire and the dimensional accuracy of the wire drawing, and a lot of smoke and dust is diffused In the workshop, it affects the workshop environment. In addition, the existing wire drawing process has many complicated steps, and some of them are drawn through the water tank wire drawing machine.

[0003] However, most of the traditional water tank wire drawing machines are integrated, which not only occupies a large area and is difficult to process, but also the entire transmission mechanism is driven by a motor, and the synchronization of the drawing process is difficult to control. In addition, as long as the motor is damaged, it must be shut down immediately for maintenance. , which seriously affects production efficiency. In addition, the traditional transmission mechanism is that the drive motor is connected to the gearbox, and the output shaft of the gearbox is connected to the main drive shaft through a chain and sprocket. This transmission structure is easily deformed during the drawing process. , and the deformation of the main drive shaft has the following defects. One is that it is very easy to cause damage to the gear of the reducer, and the existing reducer is inconvenient to disassemble and maintain; As a result, the sealing of the wire drawing water tank is not good, resulting in the leakage of the emulsion
