Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically a small-scale dust removal shot blasting machine for casting production. Background Technology

[0002] A shot blasting machine for casting production is a device used to clean the surface of castings. It uses a high-speed rotating shot blasting wheel to spray shot (such as steel shot) onto the surface of the casting to remove surface dirt and oxide layers.

[0003] Shot blasting machines for casting production have the following main components:

[0004] Shot blasting chamber: The core area used to place castings and perform shot blasting.

[0005] Shot blasting wheel: Driven by a motor, it propels shot material onto the surface of the casting at high speed.

[0006] Dust collection system: Used to collect and process generated dust and waste to ensure a clean working environment and safe operation.

[0007] Conveying system: Used to feed castings into the shot blasting chamber and automatically start the shot blasting machine.

[0008] Control system: Used to set and adjust the operating parameters of the shot blasting machine to ensure the quality of castings and production efficiency.

[0009] Using shot blasting machines in casting production can improve the surface quality and adhesion of castings, and enhance their corrosion resistance. Furthermore, shot blasting machines can reduce manual cleaning workload and time, thereby increasing production efficiency.

[0010] Existing small-scale shot blasting machines for casting production cannot effectively and automatically clean the dust and waste on the surface of the shot during shot blasting operations. Manual cleaning is still required after the shot is removed, which affects the working efficiency of the shot blasting machine and the processing quality of the castings. Utility Model Content
