Description

Shot blasting device

technical field

The present invention relates to a large-scale shot blasting device, which is used for deburring a large number of relatively large objects to be processed.

Background technique

Conventional shot blasting machines are used to remove fine burrs adhering to small molded products.

However, recently, there is a demand for removing burrs attached to larger molded products. As a countermeasure, the size of the cylinder is increased, and the projection material and the projection machine are increased in size. The agitating plate is a rectangular plate. If it is enlarged according to the size of the object to be processed, there will be the following disadvantages: the projected material will be hindered, or since the agitating plate is installed in a state where the installation angle is perpendicular to the bottom surface of the cylinder, the object to be processed will be damaged. It cannot be fully stirred without being placed on the stirring plate.
