Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a forging shot blasting machine. Background Art

[0002] Shot blasting machine is a casting equipment that uses high-speed projectiles thrown by shot blasting machine to clean or strengthen the surface of castings. It is mainly used for sand removal, core removal and cleaning of castings. It can also be used to remove burrs, diaphragms, rust and other contaminants on the surface of workpieces, so as to achieve the purpose of cleaning, strengthening and improving the surface quality of workpieces, increase the corrosion resistance, wear resistance, fatigue strength and fatigue limit of workpieces, and increase the stability and applicability of workpieces during use.

[0003] When a shot blasting machine processes forged parts, the forged parts are usually hung on a suspension frame inside the machine, and the suspension frame is then driven to rotate. At the same time, high-speed rotating projectiles are thrown to the surface of the workpiece through the shot blaster to process the workpiece. However, during the rotation of the suspension frame, for the workpiece surface close to the central axis of rotation of the suspension frame, there may be a situation where the workpiece surface on this side has less contact with the projectile, resulting in poor processing effect on the workpiece. For this reason, we propose a forged part shot blasting machine. Utility Model Content

An annular fixing block is fixed on the top inner wall of the shot blasting machine body. An annular groove matching the baffle is opened at the lower end of the annular fixing block, and the upper end of the baffle is arranged in the annular groove.

[0011] Among them, the support assembly includes an annular support block arranged on the lower side of the connecting shaft, a first fixing rod is symmetrically fixed on both sides of the annular support block, and a second fixing rod is symmetrically fixed on the other two sides of the annular support block, and the ends of the first fixing rod and the second fixing rod away from the annular support block are fixedly connected to the inner wall of the shot blasting machine body.
