Today, Wuxi IDEAL Machinery will introduce the shot blasting machine. What are the factors that affect the strength of the shot blasting machine? Next, the manufacturer of shot blasting machine will come with us to understand. Shot blasting machine refers to the casting equipment that uses the high-speed shot thrown by the shot blaster to finish or strengthen the surface of the casting. The shot blasting machine can simultaneously sand out, remove the core and finish the casting. Some areas are also called sanding machines and sandblasting machines verbally.

1、 Shot blasting speed

The strength of shot blasting machine increases with the addition of shot blasting speed, but the faster the shot blasting speed is, the higher the shot blasting damage rate is.

2、 Size of shot blasting

The greater the shot blasting volume of the shot blasting machine, the greater the impact force, the greater the strength of the shot blasting machine, but the lower the shot blasting coverage. Therefore, on the premise of ensuring the strength of shot blasting, it is also necessary to use smaller steel shot as much as possible. In addition, the shot peening ratio is also constrained by the shape of the part. If there is a groove on the part, the diameter of shot blasting is less than half of the radius of the inner circle of the groove.

3、 Shot blasting hardness

If the hardness of shot blasting is higher than that of the part, changing its hardness will not affect its strength. When the shot blasting hardness is lower than the part hardness, the shot blasting strength decreases with the decrease of hardness value.

4、 Shot blasting

After impact failure, the impact kinetic energy decreases, and the more broken the impact is, the lower the impact strength is. Because of the irregular shape, the broken steel shot will damage the appearance of the parts, so it is necessary to clean the broken steel shot regularly to ensure that the shot blasting rate is above 80%.

It is important to know the speed of shot peening, but we also need to know clearly that the speed and intensity of shot peening will increase, and the relationship between them is proportional. Secondly, the range of shot peening is large, the impact force is large, and the impact force is naturally increased, but the shot peening intensity can generally be guaranteed. On the premise of selecting the appropriate ball, the coverage rate of steel ball will decrease.

Secondly, the hardness and crushing amount of shot blasting will also affect the shot strength of the crawler shot blasting machine. If the shot blasting hardness is greater than the part hardness, it will not have much impact without changing the shot blasting hardness. If the hardness of shot blasting is less than the hardness of parts, the strength of shot blasting will decrease with the decrease of its hardness value. In addition, when the shot blasting machine is damaged, the shot blasting strength will decrease. If the broken steel shot is not sorted in time, its irregular shape will damage the appearance of the machine parts.

What we want to introduce is the effect of the radiation angle on the projection intensity. When the shot blasting jet and the surface to be sprayed are always straight, the shot blasting intensity is high. Therefore, we suggest that if shot blasting can be carried out continuously under this condition, good operation results can be achieved.
