Shot blasting machine Do you understand the importance of workpiece cleaning? The following is a brief introduction of the shot blasting machine manufacturer:

The shot blasting machine is welcomed by manufacturers because of its special role in shot blasting cleaning. What are the characteristics of the shot blasting machine? Shot blasting can evenly remove the rust layer on the surface of forgings and remove some oxide skin and burrs. The shot blasting machine removes the impurities attached to the forging surface, making the forging more smooth and beautiful. The quality of forgings can also be improved through the cleaning of shot blasting machine.

Importance of workpiece cleaning of shot blasting machine:

1. In the process of cleaning the workpiece of shot blasting machine, multiple inspection methods should be used to identify the casting quality, so this process is the general gateway for quality control.

2. In the cleaning process, it can not only change the internal organization of the workpiece, improve its mechanical properties, but also improve the surface quality and precision of the workpiece, and also repair defects to a certain extent. Therefore, this process is also the post Z pass of quality upgrading.

3. There are many types of shot blasting machine involved, such as cutting, welding repair, grinding, heat treatment, etc. A little carelessness will lead to new defects or even waste products. Therefore, it is very important to clean the workpiece of shot blasting machine.

4. The labor force for iron castings cleaning process accounts for 15-20% of the total, the cleaning cost accounts for 25% of the total cost of castings, the labor force for steel castings cleaning accounts for 25-30% of the total cost, and the cleaning cost accounts for 30-35% of the total cost. The energy consumption of cleaning process accounts for 3~10% of the total energy consumption.

5. The workpiece of shot blasting machine is made of different materials and various varieties, the position of pouring outlet is complex and changeable, and the size and shape of flash burr are different. Therefore, 60~70% of the cleaning work is still done by hand, plus dust, vibration, noise, arc light and radiant heat. Casting cleaning process has always been the weak link of high labor intensity and poor labor conditions in casting production, so the cleaning of shot blasting machine workpiece is very important.


Main factors influencing the price of shot blasting machine

1. Shot blasting speed

When the shot blasting speed increases, the shot blasting strength also increases, but when the speed is too high, the shot blasting damage increases.

2. Hardness of shot blasting

When the shot blasting hardness is higher than the part hardness, the change of its hardness value will not affect the shot blasting strength; When the shot blasting is softer than the part, if the hardness value of shot blasting decreases, the shot blasting strength will also decrease.

3. Injection angle

When the shot blasting jet is perpendicular to the surface to be shot blasted, the shot blasting intensity is high, and it should generally be kept in this state. If the shape of parts is limited, small angle shot peening must be used, and the size and speed of shot peening shall be appropriately increased.

4. Crushing amount of shot blasting

The kinetic energy of shot blasting is low. The more broken shot blasting is, the lower the shot blasting intensity is. Irregular broken shot will scratch the surface of parts. Therefore, the chipped shot shall be removed frequently to ensure the shot peening integrity is greater than 85%. The shot blasting equipment is basically the same, and only some auxiliary devices are needed to control the shot blasting process more strictly.

5. Shot blasting size

The larger the shot blasting, the greater the impact kinetic energy and the greater the shot blasting intensity, but the coverage of shot blasting is reduced. Therefore, smaller shot blasting shall be selected as far as possible while ensuring the shot blasting strength. In addition, the shot size is also limited by the part shape. When there is a groove on the part, the shot blasting diameter shall be less than half of the inner circle radius of the groove. The shot blasting particle size is usually 6~50 mesh.
