The workpiece after the shot blasting can get a good material color, and can also become the previous process of the blackening, bluish, passivation and other processes of the surface of the metal parts. At the same time, it can provide a good base for plating, paint and other finishing . After the shot blasting by the shot blasting machine, the workpiece can reduce the tensile stress and at the same time refine the surface grains, thereby strengthening the surface of the workpiece and increasing its service life.

Visual inspection: No rust spots, scales or dirt on the surface, it is required to reach the grade Sa2.5-Sa3 of the grading table: "completely remove rust and scale, without leaving any tiny marks, the steel surface is uniform silver-white metallic luster." Due to the heat treatment process, the workpiece shows a slight oxidation color after shot blasting.

Both shot blasting and sand blasting can clean and decontaminate the workpiece. The purpose is to prepare for the next sequence, that is, to ensure the roughness requirements of the next process, and some in order to ensure the consistency of the surface. The strengthening effect is not obvious. Generally, shot peening is small steel ball, and sand blasting is quartz sand. According to different requirements, divide the number of heads.

Shot blasting mechanism: Its function is to throw steel shots to the surface of the object to be treated at a certain angle and speed to obtain the effect of removing the surface layer of the object. It consists of a motor, a wheel, a pill supply room, a shot blasting room, a guide tube, left and right guard plates, a center plate and a top plate.

Each machine is in a running-in period when it is first used. The causes of machine failures during this period are very complicated. For example, a shot blasting machine is a machine that often fails during the running-in period. There are many reasons for this kind of failure, and even basic selection problems may cause the machine to malfunction during the work.

After we bought the sandblasting machine, can we use it immediately? The answer is no, because it can only be officially put into use after debugging, and debugging is very important. If the debugging is not good, then there will be problems during the use of the sandblasting machine. Then we will elaborate on this content , The specific content is as follows.

Guard plate in shot blasting machine The material of the guard plate in the shot blasting machine is generally cast iron, because when heat treatment is carried out, as long as different heating and holding temperatures are controlled, cast iron with different performance characteristics can be obtained, so it can meet different needs . Therefore, the material of cast iron is used to manufacture the guard plate.

Shot blasting machinery, although there are only four words, but it contains a lot of professional knowledge,

Shot blasting machine, which is a kind of machine equipment, and is a common and commonly used equipment in mechanical processing,

There are many different types of shot blasting machines, but due to the limited space of the article, and in order to ensure that everyone has a good learning quality and learning effect,

Always check the wearing parts in the shot blasting equipment, mainly to see whether it is seriously worn and whether to replace new parts.

Shot blasting machinery is a website product and keyword, so for all of us, it is an object that needs to be familiar with and understand,
