Problems solved by technology

The traditional method is to use shot blasting to remove the thermal oxide layer, and its disadvantage is that the dust pollution is large, and the surface of the valve is prone to micro-cracks, which are not bright
The traditional valve polishing equipment uses a shot blasting machine to directly spray iron shot onto the surface of the valve through a spray gun under the action of compressed air, so that the surface of the valve after treatment is prone to micro-cracks and is not bright

Abstract

The invention relates to a polishing technology, in particular to a mixed polishing method and a device thereof suitable for air valves. In the mixed polishing method of the invention, an air valve after heat treatment is loaded into a rotary drum, and after chemical acid dipping and alkali neutralization, abrasive particles are loaded in, thereby realizing chemical and mechanical mixed polishing of the air valve through the rotation of the rotary drum in a chemical treatment solution. The invention can effectively remove an oxide layer after heat treatment of the air valve, and realize polishing of the non-mechanically processed surface of the air valve on the premise of no generation of microcracks.

Description

technical field [0001] The invention relates to a polishing process, which belongs to the technical field of chemical polishing, in particular to a hybrid polishing method and device for valves. Background technique [0002] The valve is a key part of the engine, and thermal oxidation layers and microcracks are not allowed to appear on its surface. The manufacture of the valve must undergo heat treatment. After heat treatment, a thermal oxide layer will appear on the surface of the valve, and some surfaces of the valve after heat treatment will no longer be machined. The traditional method is to use shot peening to remove the thermal oxide layer, and its disadvantages are that the dust pollution is large, and the surface of the valve is prone to micro-cracks, which are not bright. The traditional valve polishing equipment uses a shot blasting machine, which directly sprays iron shot onto the valve surface through a spray gun under the action of compressed air, so that the t...
