Ring forging in the process of processing, easy to cause some influence on the surface quality of the forging, which also includes the surface of the forging appeared a stain. In the process of forging, we should try to avoid the quality of forging problems, so we should master the way to clean up the residual dirt in the processing of forging. Because in processing, we need to change the performance of the forging, and sometimes make these metal parts after heating treatment, in this process, due to the influence of temperature, will make the forging oxide layer. Normal forgings are not allowed to appear surface defects, so we should deal with this situation in time. In the forging processing, we not only change the characteristics of the metal, but also the performance of the forging has been improved. When the forging is used, we can only ensure that the quality of the forging is not affected, in order to make the stable performance of the forging play. To ensure the strength of the forging, it should make the forging in processing without any gap or excess material, but also should meet the requirements of forging in strength. When cleaning stains in forging, the main objective is to remove burrs and beryllium oxide from ring forging.
Ring forgings in cleaning, we commonly use two methods, including horizontal drum cleaning and shot blasting drum cleaning. Let's first look at the horizontal cylinder cleaning, this cleaning is the size of many bearing rings at the same time into a certain speed, reversal of the horizontal cylinder, through migration, change and impact with each other, so that beryllium oxide on the forging surface off clean. At the same time of rotation, it can also polish the burr and edge of the forging, so as to speed up the cleaning work of the forging. Sometimes also in the drum into some scrap ball, should pay attention to the cleaning time should be controlled, otherwise it will directly affect the quality of cleaning. Another cleaning method is the shot blasting drum cleaning, the forgings into the low speed rotation of the horizontal sealing drum, the use of iron pellets is relatively small, when the iron pellets from the high-speed migration of the shot peening blade, the iron pellets rushed to the forgings, will make beryllium oxide due to impact and fall off. In this process, the steel pellets can be automatically recycled, and the beryllium oxide will be sucked out in time by the vacuum cleaner.
