Description

Technical Field

[0001] This utility model relates to the field of metal surface treatment technology, and in particular to a shot blasting device for parts. Background Technology

[0002] A shot blasting machine is a casting equipment that uses high-speed shot blasting to clean or strengthen the surface of castings. Shot blasting machines can simultaneously remove sand, cores, and clean castings. In some regions, they are also colloquially called sandblasting machines or sandblasting machines. Shot blasting differs from shot peening machines; it is used to reduce the fatigue life of parts, increase different surface stresses, increase component strength, or prevent fretting. Shot blasting machines can also be used to remove burrs, diaphragms, and rust, which may affect the integrity, appearance, or definition of an object. Shot blasting machines can also remove surface contaminants from partially coated surfaces and provide a surface profile that increases coating adhesion, thereby strengthening the workpiece. Existing shot blasting devices for parts have drawbacks: parts are difficult to disassemble and assemble, the device cannot thoroughly perform shot blasting, and the impact of the shot generates a lot of noise, making quiet shot blasting impossible.

[0003] Chinese Patent Publication No. CN 217530501U discloses a shot blasting device for parts. When a parts hanger suspends and fixes the parts, a quick-release sleeve can be inserted, installed, and removed quickly via a snap-fit ​​groove and a rotating connecting shaft. Therefore, the parts hanger can be installed and removed from outside the device before being placed into the processing chamber for shot blasting. Simultaneously, a rotary motor drives the rotating connecting shaft to rotate, which in turn rotates the parts hanger. This achieves the goal of rotating the parts during shot blasting, resulting in a more thorough shot blasting process and facilitating the use of the parts. The assembly and disassembly of the equipment utilizes a sound-absorbing base plate structure. During shot blasting, steel shot falls to the bottom of the processing chamber and impacts the top contact plate, generating sound. Multiple sound-insulating partitions are installed between the top contact plate and the bottom buffer plate, forming a multi-layered structure that isolates the impact sound. Furthermore, multiple elastic buffer strips at the bottom of the bottom buffer plate cushion the impact force at the bottom of the processing chamber, minimizing noise during shot blasting and reducing noise generation during equipment use, allowing for quieter shot blasting operations.

[0004] However, when using the aforementioned patent, the shot blasted projectiles contain a large number of impurities and broken projectiles. There is a lack of separation devices to screen and recycle the projectiles, which is not conducive to energy conservation and emission reduction and results in high operating costs.
