Description

Technical Field

[0001] The present invention relates to the technical field of shot blasting machines, and more particularly to a four-throw high-efficiency shot blasting machine for workpiece surface processing. Background Art

[0002] Shot blasting machine refers to casting equipment that uses high-speed projectiles thrown by shot blasters to clean or strengthen the surface of castings. Shot blasting machine can simultaneously remove sand, core and clean castings. In some areas, it is also verbally called sandblasting machine or sandblasting machine. Drum-type and chain-plate shot blasting machines are suitable for cleaning small and medium-sized castings that are not afraid of collision. Drum-type shot blasting machine relies on spiral guide ribs in the cylinder to make the casting flip and move forward. Chain-plate shot blasting machine uses the movement of chain plates to make the casting flip and run. Turntable, trolley and hanging shot blasting machines are used to clean large and medium-sized castings. They are usually equipped with fixed shot blasting chambers. The cleaned castings rotate or move in the shot blasting chamber. The shot blasting chamber is generally equipped with Several shot blasting machines are installed in different positions and projectiles from different directions to improve the cleaning efficiency and cleaning quality of the shot blasting machine. The hanging shot blasting machine can be equipped with several hooks on the catenary according to the needs of the castings to be cleaned. The castings are hung on the hooks during cleaning and turn over by themselves while running forward. The castings are loaded and unloaded outside the shot blasting room and cleaned indoors. The drum shot blasting machine mainly uses the high-speed rotating impeller to throw the projectiles onto the workpieces that are continuously turned over in the drum, so as to achieve the purpose of cleaning the workpieces. It belongs to the range of casting machinery. It is suitable for sand removal, rust removal, oxide skin removal and surface strengthening of castings and forgings weighing less than 15 kg in various industries.

During the processing and cleaning process, traditional shot blasting machines will have problems such as local jamming and a single throwing angle when throwing shots, resulting in a decrease in the workpiece cleaning processing efficiency and the inability to reduce the actual cleaning dead angles of the workpiece.
