The wire drawing machine is a kind of mechanical equipment that is widely used in industrial applications. In the actual operation process, different users have different requirements for the thread pattern, so it is required that the wire drawing machine should be dealt with in a targeted manner. The first is about the processing method of the snow pattern, which is generally for square tubes. Because of the difficulty of this process, most of them will choose an automatic wire drawing machine.
In addition, the rotation speed and swing frequency of the machine must be specified in color, otherwise the line pattern will easily fail to meet the requirements; in addition, the selection of abrasive materials is also very critical, which directly affects the visual and feel of the snow pattern. It is said that there are more drawing wheels or nylon belts.
In addition, it is the treatment of hairline, which can be done by most wire drawing machines, such as ordinary flat wire drawing machine, manual wire drawing machine, automatic wire drawing machine, flat wire drawing machine, etc. The selected abrasive materials are small roller brushes and Baijie. There are two kinds of cloth, under their action, can obtain more ideal results.
In the process of wire drawing, the compression rate set by the wire drawing machine is unreasonable, which will cause scars or cracks in the die of the wire drawing machine. This situation is generally caused by the release of internal stress. There is nothing wrong with the internal stress of the material, and the internal stress generated by the wire drawing machine when drawing the wire can actually improve the microcrystalline structure of the mold, but if the compression ratio of the drawing surface exceeds the normal value, the surface will be caused by the failure of normal lubrication. The temperature rises, causing part of the material on the surface of the mold to be transferred, its stress will increase, and the wear will be aggravated.
During the wire drawing process, due to the mismatch between the position of the material and the die hole, in this case, the stress on the material and the wire drawing die will fluctuate, and the impact generated by the vibration of the wire drawing machine will also affect the wire rod and the wire drawing die. Causes high stress peaks, which makes the wear of the mold more serious.
During the operation of the wire drawing machine, factors such as unbalanced production quality of materials due to annealing problems may cause premature fatigue of the diamond wire drawing die, forming an annular groove, thereby accelerating the wear of the die hole. It may be due to the condition of the material. If the surface of the processed wire is not smooth, and it is also contaminated with other impurities such as oxide layer, sand, etc., it will cause the mold to wear out too quickly.
When the wire of the wire drawing machine passes through the die hole, the above oxide layer or other adhering impurities will cause the die hole of the wire drawing die to wear quickly and scratch the surface of the wire. If the lubricating quality is unqualified, in the drawing process of the wire drawing machine, the die hole will heat up quickly due to the lack of proper lubricating protection, causing damage to the die.
