Abstract
Description
Technical Field
[0001] This utility model belongs to the field of shot blasting machine technology, and specifically relates to a shot blasting machine. Background Technology
[0002] Shot blasting is a casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. It can simultaneously remove sand, cores, and clean castings. Most cast steel parts, gray cast iron parts, malleable iron parts, and ductile iron parts require shot blasting. Shot blasting removes oxide scale and adhering sand from castings, removes burrs from die castings, and achieves a decorative surface finish. It also allows for quality inspection, detecting surface defects such as subcutaneous porosity, slag inclusions, adhering sand, cold shuts, and peeling, improving the reliability of flaw detection results. The shot used in shot blasting is typically steel shot, propelled onto the casting surface by a shot blasting device within the machine. The steel shot is thrown at a specific angle; as the throwing distance increases, the shot tends to veer to the sides, potentially leading to uneven shot blasting and affecting product quality.
