| Attentions should be paid to the problems in the process of wire drawing machine： Because of the uninterrupted production of copper wire drawing machine equipment, the drawing speed will gradually not synchronized with annealing, which makes wire diameter appeared discontinuous and irregular change due to the traction speed of the fast or slow when drawing. The causes of this phenomenon are as follows: 1. the wear caused by long-term use of the main motor gear box. This will make the drawing capstan speed and traction speed and take-up speed does not match, thus formed a monofilament stretched. 2. The tension of line storage wheel is instability. The areas which use of pressure in the production workshop may be large, this will cause the pressure pump drawing machine big or small, it also makes a line tension not constant, but because of the take-up speed is constant, this makes the wire drawing by force also not a constant value, which will cause the single outside diameter deviation can not accurate control. 3 copper wire vibration on the annealing wheel. Which makes the copper wire annealing in the tight or loose state, annealing current density is big or small, and the strength of the copper wire in high speed is relatively low, so it ‘s easy to cause the copper wire annealing wheel lighter, so that the copper surface of the spark and wire diameter is not uniform. Solution: good lubrication on the line, to avoid when running at high speed on the friction force caused by reverse and the fine line; adjust the line tension, making the drawing stroke always clings to the annealing wheel; ensure the annealing wheel steel ring intact, avoid the steel surface defect and the annealing current instability. Re-mold the wire drawing machine according to the actual situation of wire drawing machine: to adjust the annealing wheel drive shaft adjustable triangular belt wheel diameter according to the principle of wire drawing, annealing wheel speed / capstan speed = forward slip coefficient #215; capstan diameter / annealing wheel diameter, the constant speed and annealing wheel diameter is known, capstan and annealing wheel speed can be measured, which can obtain the forward slip, the slip coefficients to model the wire drawing machine, this distribution of mold can meet the requirements. |
