Stable operation and installation requirements of inverted wire drawing machine

If there are a lot of oil stains or impurities on the surface of the wire rod of the inverted wire drawing machine, it should be cleaned and dried before drawing. If there is more oxide skin on the surface of the wire rod, it needs to be pickled and dried before drawing.

If there are problems such as peeling, pits and double skin on the surface of the inverted wire drawing machine, it is necessary to use the polishing machine for grinding, and then the wire drawing machine equipment can be used for drawing. After the surface is pretreated, it needs to be heated. If we find that the hardness of the wire rod is relatively large or uneven, it is necessary to reduce the hardness by annealing or tempering to make the wire rod reach a relatively uniform hardness before drawing. In the heat treatment, there are many disadvantages in the traditional wire drawing machine. Usually, in the heat treatment, the traditional heating methods used in the past mainly include two kinds: combustion heating and cathode heating.

In order to ensure the stable operation of the handstand wire drawing machine, there are many methods that can be used. At the same time, some requirements are put forward for the users of the wire drawing machine. In order to keep the equipment in stable production state, it is necessary to ensure the rationality of its installation. During the installation of the equipment, it is necessary to ensure that the installation foundation is fixed firmly to avoid vibration, and debugging is also required to ensure that the drawing axis of the wire rod is symmetrical with the center line of the die hole, so that the stress of the wire rod and the drawing die is uniform. Secondly, it is necessary to ensure the rationality of operation during the production of wire drawing machine.

During the drawing operation of the inverted wire drawing machine, the operator should operate in a standard manner and avoid starting and stopping frequently as much as possible, because the friction caused by the tensile stress at the beginning of drawing is much larger than that during normal drawing, which will increase the wear of the die. And before drawing, it is necessary to conduct proper pretreatment for wire rod, which is generally surface pretreatment and heat treatment.

During the operation of the inverted wire drawing machine, attention should be paid to its detection. Generally, the operation state can be monitored by detecting the changes of voltage and current. We should know that during the operation of the equipment, any fluctuation may directly affect the control effect of its operation. Therefore, we can also improve its operation state from the control aspect. Based on this theory, we can improve the control system of wire drawing machine and add the corresponding frequency converter. In this way, by detecting the DC side current of the frequency converter, the variation of the equipment load can be fed back, so as to find out a certain control law. In this way, the speed regulation progress can be improved and the process can be satisfied.
