Shot blasting machine for aluminum alloy castings

Abstract

The invention discloses a shot blasting machine for aluminum alloy castings, and specifically relates to the technical field of shot blasting machines. The shot blasting machine comprises a device base, a device body is fixedly arranged at one end of the top of the device base, a shot blasting chamber is fixedly arranged at the top of the device body, a screening recycling bin is fixedly arrangedat the bottom of the shot blasting chamber, a screening mesh plate is fixedly arranged in the middle of the screening recycling bin, the screening mesh plate is arranged in an inclined manner, a recycling hopper is fixedly arranged at the bottom end of the screening mesh plate, a shot blasting device is fixedly arranged at the top of the shot blasting chamber, and a spiral conveying cylinder is fixedly arranged at the top of the shot blasting device. According to the shot blasting machine, recycling and screening are conducted through the screening recycling bin, steel balls or steel shot rolls on the inclined screening mesh plate and falls into the recycling hopper, a conveying belt in a lifting material frame is lifted to the spiral conveying cylinder, the steel balls or steel shot is evenly distributed to the shot blasting device through the spiral conveying cylinder, cyclic operation of the steel balls or steel shot is achieved, the workload is reduced, and the work efficiency is affected.

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 the oxide 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 inspection to ensure the inspection result. reliability. In the production of general castings, shot blasting is an indispensable process for discovering casting surface defects such as subcutaneous pores, slag holes, sticky sand, cold insulation, and peeling. Shot blasting machine refers to the use of shot blasting equipment to throw High-speed projectile cleaning or casting equipment for strengthen...

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
