Torsion bar shot blasting machine

Abstract

The invention provides a torsion bar shot blasting machine, and a shot throwing port has a trumpet-shaped opening, thereby increasing a shot throwing distribution; the contact surface of blades and shots is an arc shaped curved surface with rough surface, thereby the thrown shots are distributed uniformly; the number of the blades on each impeller is 6 or 8, thereby guarantying operation balance property of the shot throwing machine, wherein, the balance moment is between 12-15 N.mm, and simultaneously reducing the equipment noise, and the weight difference of each set of blade is not less than 3g. The motor employs a direction connection transmission, thereby minimizing belt power loss and the energy consumption reduces 16-19%. A shot distributing wheel, a control cage, the impeller, the blade and the cover casing all employ wear resistant cast iron whose chromium content is higher than 18%, thereby increasing wear resistance of components and improving machine life; and the shot blasting amount of the shot blasting machine is up to 320kg / min, and the shot blasting speed is up to 88m / s, thereby the component life is increased to 4 times, and the noise is reduced to 45%, and the work efficiency is effectively increased.

Description

technical field [0001] The invention relates to a shot blasting machine, in particular to a shot blasting machine used for a torsion bar of an automobile transmission system. Background technique [0002] Shot blasting is required during the processing of the torsion bar. Shot blasting is a treatment technology that uses a shot blasting machine to drop steel sand projectiles at high speed and impact on the surface of the torsion bar. It can better remove the rust and splash on the surface of the torsion bar, and increase the friction coefficient on the surface of the torsion bar. The traditional shot blasting machine mainly uses the high-speed rotating blades in the shot blaster to throw the projectiles, and hits the surface of the parts at high speed to meet the requirements of surface treatment. However, the blades of the traditional shot blasting machine throw uneven distribution of projectiles during the working process, and the distribution area of ​​the projectiles is...
