An automatic mold-threading device and a mold-threading method using the device

Abstract

The invention belongs to the technical field of copper wire threading, in particular relates to automatic threading equipment and a threading method applying same. According to the automatic threadingequipment and a threading method applying the same can simply and quickly realize the automatic threading function of finished copper wires with specified diameters. The automatic threading equipmentcomprises a first die base, a first clamp, a clamping and conveying roller, a second clamp, a third clamp, a first induction baffle, a second die base, a conveying clamp, a fourth clamp and a secondinduction baffle which are sequentially arranged in the traveling direction of the copper wire. The threading method comprises the following steps that, the clamping and conveying roller feeds a copper wire; the first clamp and the third clamp break the copper wire to form a sharp point at the breakpoint of the copper wire; the second clamp clamps the copper wire and feeds the copper wire into thesecond die base; the fourth clamp draws the copper wire; the conveying clamp clamps a mold of the current process and feeds the mold into the first mold base, and meanwhile, the fourth clamp descendsand discharges the copper wire; and the conveying clamp and the fourth clamp are reset, and the second induction baffle is reset and the above steps are continuously repeated in sequence until all the molds in the second die base are used up.

Description

technical field [0001] The invention belongs to the technical field of copper wire threading, and in particular relates to an automatic threading device and a threading method using the device. Background technique [0002] At present, copper wire production generally adopts Ф5.5mm, Ф6.5mm, Ф8.0mm, etc. cold-rolled wire rods to undergo multiple drawing, intermediate heat treatment, surface treatment and other processes to obtain copper wires with required wire diameters, and then Then a plurality of copper wires are twisted into a wire and subjected to subsequent processing to finally obtain a finished wire. During the drawing process, no matter dry drawing or wet drawing, the copper wire needs to be processed and deformed through the die hole of the wire drawing die, and finally the finished copper wire with the required diameter is formed. Usually, for the drawing of copper wire, the operator needs to manually sharpen the copper wire head on the grinding wheel, and then i...

AI Technical Summary

Problems solved by technology

The finished copper wire with a specified diameter is obviously not able to meet the diameter requirement of the finished copper wire through one pass through the mold. It often needs to rely on multiple sets of wire drawing dies with gradually decreasing die hole diameters, and repeat the above operations more than ten times or even more than twenty times. Finished copper wire; in each drawing process, the copper wire is initially pulled out of the drawing die for a distance of about one meter, which must be completed by manual operation; especially for some thicker copper wires, the above The manual pulling operation is even more difficult, and sometimes several operators are required to complete it together

Obviously, the above-mentioned entire operation process is cumbersome and complicated, and the labor intensity is extremely high; while time-consuming and labor-intensive, the operation efficiency cannot be further improved, which seriously restricts the actual economic benefits of copper wire manufacturers.
