The wire drawing machine is a kind of mechanical equipment that is extremely widely used in industrial applications. In the actual operation process, different users have different requirements for the thread pattern. Therefore, the wire drawing machine is required to be dealt with in a targeted manner. The first is about the processing method of the snow pattern, which is generally for the square tube. Because this process has a certain degree of difficulty, most of them will choose the automatic drawing machine. In addition, the color of the machine's speed and swing frequency must be specified, otherwise the line pattern will easily fail to meet the requirements; in addition, the choice of abrasive materials is also very critical, which directly affects the visual and feel effects of the snow pattern. In other words, drawing wheels or nylon belts are often used.
In addition, it is the processing of hairline lines. Most of these lines can be completed by wire drawing machines, such as ordinary flat wire drawing machines, manual wire drawing machines, automatic wire drawing machines, flat wire drawing machines, etc. The selected abrasive materials are small roller brushes and Baijie Two kinds of cloth, under their action, can obtain a more ideal effect.
In the process of drawing, the compression rate set by the drawing machine is unreasonable, which will cause the die of the drawing machine to be scarred or broken. This situation is generally caused by the release of internal stress. The internal stress of the material is understandable, and the internal stress generated by the wire drawing machine can actually improve the microcrystalline structure of the die, but if the compression rate of the drawing surface exceeds the normal value, the surface will be caused by the failure of normal lubrication. The temperature rise will cause part of the material on the mold surface to be transferred, and its stress will increase and aggravate the wear. In the process of drawing, due to the mismatch of the position of the material and the die hole, in this case, the stress on the material and the drawing die will fluctuate, and the shock generated by the vibration of the drawing machine will also affect the wire and the drawing die. Causes a very high stress peak, which makes the wear of the mold more serious.
During the operation of the wire drawing machine, due to the annealing problem, the uneven production quality of the material and other factors may cause the diamond wire drawing die to fatigue prematurely and form an annular groove, thereby accelerating the wear of the die hole. It may be caused by the condition of the material. If the surface of the processed wire is not smooth, and it is also contaminated with oxide layer, sand and other impurities, it will cause the mold to wear out too quickly.
When the wire of the wire drawing machine passes through the die hole, the oxide layer or other adhering impurities on it will cause the die hole of the wire drawing die to wear quickly and scratch the surface of the wire. If the lubrication quality is unqualified, the die hole will heat up quickly due to the lack of proper lubrication protection during the drawing process of the wire drawing machine, causing damage to the die.
