Frequent copper wire breakage occurs during the wire drawing process, which greatly affects the production progress. This situation is mainly caused by the following factors:
1.The sizing area of the wire drawing die will become larger due to normal wearand tearduring uninterrupted production.
2.Wire quality issues.Duringthe production process, the wire irregularly appear to have quality defects, which makes the wire to be broken in the drawing deformation by a variety of unpredictable tension,such as moisture. This condition is less present when the wire is in good condition.
3.The annealing current during production is not constant, the current is suddenly high, and the wire is drawing off during the annealing process or fused by the sudden strong current.
4.The wire connection is not secure. The current, power-on time and pressure of the welding machine will affect the welding quality. If the welding quality is not up to standard, the wire will frequently break.
So how do we solve the frequent copper wire breakage in wire drawing production ?
1.According to different wireselection of different mold scheme, in the production of continuous exploration. For example, in the production of the copper wire produced by the upper drawing method, the 2.53mm single wire needs 8 wire drawing dies.The production of the same outer diameter of the single wire, if the rolling rod is used, it is necessary to add a bridge die when the mold is matched according to the requirements.
2.Before the production, it is necessary to do a full self-test on the copper wireto be produced.Find the quality shortcomings of the copper rod in time.Find the corresponding countermeasures in time according to different conditions, such as reduce the drawing speed, remove the shortcomings of this section.
3.In the production of wire drawing machine, it is necessary toobserve constantly whether the annealing current of wire drawing is normal, especially when it is just started. Pay special attention to the change of annealing current, adjust the size of the annealing current according to the change of wire speed.And then make the annealing current
As long as the above points are focused on the control of the actual production, the quality and production power of copper wire drawing products will be improved to different degrees.So that the production of the next process can be provided with a strong production guarantee.
