Energy-efficient spring reinforced shot blast machine

Abstract

The invention relates to an energy-efficient spring reinforced shot blast machine. The technical schemes of the invention comprise that: the shot blasting machine comprises shot blast cleaning chambers and shot blast devices; a steel shot separator is arranged fixedly above the blast cleaning chambers; the steel shot separator comprises an upper tank body, a separation tank body and a shot storage tank body, wherein the upper tank body, the separation tank body and the shot storage tank body are connected respectively in a top-to-bottom order; the separation tank body is separated into three parts of a material feeding chamber, a winnowing chamber and a miscellaneous material loading chamber; an upper portion of the material feeding chamber is communicated with the upper tank body and an lower portion of the material feeding chamber is communicated with the winnowing chamber through a feed opening; the winnowing chamber is provided with an air inlet opening and a catching plate mechanism which is utilized for adjustment of feed opening size and is arranged in the winnowing chamber, wherein the bottom of the winnowing chamber is communicated with the shot storage tank body and a side portion of the winnowing chamber is communicated with the miscellaneous material loading chamber; the miscellaneous material loading chamber is provided with an air door adjusting mechanism at a location where the miscellaneous material loading chamber and the winnowing chamber are communicated, wherein the miscellaneous material loading chamber is provided with an air outlet opening at the upper portion, and a waste material outlet opening at the bottom; and the shot storage tank body is provided with shot outlet openings communicated with the shot blast devices. The steel shot separator utilized in the reinforced shot blast machine utilizes a winnowing way and has the advantages of requiring no mechanical power and reducing power consumption. The whole energy-efficient reinforced shot blast machine has the advantages of low energy consumption, reliable service behavior, energy conservation and environmental protection.

Description

technical field [0001] The invention relates to equipment for strengthening the surface of automobile suspension springs after heat treatment, in particular to an energy-saving spring strengthening shot blasting machine. Background technique [0002] After heat treatment, the automobile suspension spring generally needs to be strengthened by shot blasting machine for surface strengthening treatment. Strengthening the spring after shot blasting can eliminate the residual stress on the surface, improve the surface strength of the spring, and prolong the service life. The existing spring-strengthened shot blasting machine is mainly composed of a shot blasting chamber, a shot blasting device, a workpiece conveying mechanism, a workpiece rotating mechanism, a screw conveyor, a bucket elevator, a steel shot sorter and a dust removal system. The shot blasting machine is located on the top of the shot blasting cleaning room. The workpiece rotating mechanism, workpiece conveying mech...

AI Technical Summary

Problems solved by technology

The steel shot sorter in the shot blasting machine adopts a spiral sorter and also has a set of screw conveyors. Therefore, the whole machine has many mechanical transmissions, which is prone to failure and consumes a lot of power.
