1. The manipulation of the diameter error of the commodity
Because of the uninterrupted production and manufacture of copper core wire drawing machines, the speed of wire drawing will also be gradually different from that of annealing, which will cause the cable diameter to be interrupted due to the speed of the traction belt during wire drawing. regular changes. The reasons for this situation are as follows:
1. The support force on the wire storage wheel is unstable. There are likely to be many areas where standard air pressure is applied to the production line, which will cause the standard air pressure of the air pump of the wire drawing machine to be high and low, which also makes the support force of the wire accumulator unstable, and because the speed of the winding wire is not Changed, which makes the tensile force of the wire drawing non-constant, which can lead to the uncontrollable diameter error of the single wire.
2. The shaking of the copper core wire on the annealing wheel. This promotes the annealing of the copper core wire when it is loose and sometimes tight, and the annealing current intensity is sometimes large and small, while the compressive strength of the copper core wire under higher speed operation is relatively low, so it is very easy to cause the copper core wire. Ignition on the annealing wheel, so that the surface of the copper core wire is uneven in diameter due to the effect of the flame.
3. Damage caused by the long-term application of the main motor reducer. This can make the speed of the constant speed pulley of the drawing wire and the speed of the pull-in angle do not match, thereby causing the thinning of the monofilament.
