Abstract

A radial forging strain-induced semi-solid state process for manufacturing an aluminum alloy crankshaft of an air condition compressor comprises the steps that an aluminum alloy bar material is preheated, radial forging is carried out on the aluminum alloy bar material, secondary remelting is carried out on a bank after radial forging, then semi-solid thixotropy forging of the aluminum alloy crankshaft is carried out, and subsequent processing of the aluminum alloy crankshaft is carried out. The uniform aluminum alloy semi-solid blank without mirodefects can be manufactured and the aluminum alloy crankshaft with fewer microstructure defects and good mechanical performance is formed and replaces a cast iron crankshaft through the process, the process is simple, and operation is easy.

Description

technical field

[0001] The invention belongs to the technical field of metal semi-solid processing and forming, and in particular relates to a semi-solid process for preparing an aluminum alloy crankshaft of an air-conditioning compressor induced by radial forging strain. Background technique

[0002] In recent years, lightweight has become a new hot spot in the industrial field. Lightweight specifically includes material lightweight, process lightweight and structural lightweight. The lightweight of materials mainly refers to the replacement of steel and copper with lightweight non-ferrous metals, such as aluminum alloys and magnesium alloys. For example, aluminum alloy has very good die-casting performance and processing performance, and the recycling efficiency is high, and the recycling process is pollution-free.

[0003] The crankshaft is one of the important moving parts in the air-conditioning compressor. At present, the crankshaft of the air-conditioning compressor...
