What are the main factors affecting the strength and performance of the shot blasting machine?
There are many factors affecting the strength of the shot blasting machine. Today, Donghai Lin Xiaobian has compiled five main factors that affect the strength of the shot blasting machine.
The main factors affecting the strength of the shot blasting machine are:
1 shot blast size
The larger the shot blast, the larger the impact kinetic energy and the greater the shot blasting strength, but the coverage of the shot blasting is reduced. Therefore, while ensuring shot blasting strength, try to use smaller shot blasting. In addition, the shot size is also limited by the shape of the part. When there is a groove on the part, the diameter of the shot shall be less than half the radius of the inner circle of the groove. Shot granule size is often selected between 6 and 50 mesh.
2 shot blast hardness
When the shot blast hardness is higher than the hardness of the part, the change of its hardness value does not affect the shot blasting strength;
When the shot blasting is softer than the part, if the shot peening hardness value is lowered, the shot blasting strength is also lowered.
3 shot blasting speed
When the shot blasting speed is increased, the shot blasting strength is also increased, but when the speed is too high, the shot blasting damage is increased.
4 spray angle
When the shot blasting jet is perpendicular to the surface to be sprayed, the shot blasting strength is high, so generally, the shot blasting treatment should be maintained in this state. If it is limited by the shape of the part, it is necessary to increase the size and speed of shot peening when shooting at a small angle.
5 shot crushing amount
The kinetic energy of the shot blasting fragment is low, the more shot blasting is broken, the shot peening strength is reduced, and the irregular broken pellets will scratch the surface of the part, so the broken granules should be removed frequently to ensure that the shot peening integrity rate is greater than 85%. The shot blasting equipment is basically the same, and only a few auxiliary devices are needed to control the shot blasting process more strictly.
One. The dust of the dust collector contains too many projectiles, the air volume of the separator is too large, and the air damper is properly adjusted until the dust removal effect can be ensured, but the projectile is not sucked out.
There are many factors affecting the strength of shot blasting machine. Today, Donghai Lin Xiaobian sorted out the five main factors affecting the strength of shot blasting machine. The main factors affecting the strength of the shot blasting machine are: ① the bigger the shot blasting size, the greater the impact kinetic energy, the greater the shot blasting strength, but the coverage of shot blasting is reduced. Therefore, while ensuring the strength of shot blasting, smaller shot blasting should be selected as far as possible. In addition, shot peening size is also limited by part shape. When there is a groove on the part, the shot blasting diameter should be less than half of the circle radius in the groove. The size of shot blasting is usually selected between 6 and 50 mesh. The hardness of shot blasting when the hardness of shot blasting is higher than the hardness of parts, the change of its hardness value
Stainless steel sand material rust, the use of sandblasting process rust removal method to process. Is there any good rust removal essentials? Sandblasting process materials mainly on metal and other workpiece surface treatment, so that other coating can better protect the workpiece surface, can also use sandblasting process to make the workpiece surface produce special effects, remove burr, sandblasting rust, solve other dirty problems, to achieve the purpose of surface decoration. Here is the Hantong industry to talk about the essentials.
