A shot blasting machine for aluminum alloy castings

Abstract

The invention discloses a shot blasting machine for aluminum alloy castings, specifically relates to the technical field of shot blasting machines, comprising a device base, a device body is fixedly arranged at one end of the top of the device base, and a device body is fixedly arranged on the top of the device body The shot blasting chamber, the bottom of the shot blasting chamber is fixed with a screening recovery bin, the middle part of the screening recovery bin is fixed with a screening screen, the screening screen is inclined, and the bottom of the screening screen is fixed with a The recovery hopper, the top of the shot blasting chamber is fixed with a shot blaster, and the top of the shot blaster is fixed with a screw feeding tube. In the present invention, recycling and screening are carried out through the screening recovery bin. Steel balls or steel sand roll on the inclined screening screen and fall into the recycling hopper. To the shot blasting machine, the circular operation of steel balls or steel sand is realized, which reduces the workload and affects work efficiency.

Description

technical field [0001] The invention relates to the technical field of shot blasting machines, in particular to a shot blasting machine for aluminum alloy castings. Background technique [0002] Almost all steel castings, gray castings, malleable steel parts, ductile iron parts, etc. must be shot blasted. This is not only to remove scale and sticky sand on the surface of the casting, but also an indispensable preparation process before the quality inspection of the casting. For example, the casing of a large gas turbine must be subjected to strict shot blasting before non-destructive testing to ensure the accuracy of the testing results. reliability. In the production of general castings, shot blasting cleaning is an indispensable process to find surface defects of castings such as subcutaneous pores, slag pores, sticky sand, cold shut, peeling, etc. High-speed projectile cleaning or casting equipment for strengthening the surface of castings. The shot blasting machine ca...

AI Technical Summary

Problems solved by technology

[0003] The prior art has the following deficiencies: when the original shot blasting machine is processing aluminum alloy castings, the steel balls or steel sand thrown by the shot blasting machine need to be recycled and reused after being thrown out, so the shot blasting machine needs to be recycled. Add new steel balls or steel grit, but the workload of adding steel balls or steel grit is large, time-consuming and laborious, which affects the work efficiency of the entire shot blasting process
