Abstract

The invention discloses a washing machine spin shaft forming process and forming dies thereof. The forming process includes the following steps: preprocessing: material is machined into a pre-cold extrusion workpiece state in a series of ways including outer circle turning, end surface machining and chamfering; half hole and outer circle extrusion: a hole and an outer circle are extruded to be formed on one end of a preprocessed workpiece by the hole extrusion die; blank cold extrusion: a shoulder is extruded to be formed on the middle of the workpiece with the extrusion-formed hole and outer circle by a shoulder extrusion die; and remaining half hole machining: the extrusion-formed half hole is machined into a through hole by a drilling machine. The washing machine spin shaft forming process has the advantages that the production efficiency is high, the precision and surface roughness of the produced part are high, and material is saved.

Description

technical field [0001] The invention relates to the technical field of washing machine dehydration shaft processing, in particular to a washing machine dehydration shaft forming process and a forming mold thereof. Background technique [0002] At present, in the process of traditional washing machine dehydration shaft processing, the processing of holes is generally completed through a series of processes such as drilling, boring, and reaming. Although this processing method is relatively simple, it has many shortcomings and deficiencies: [0003] 1. Low production efficiency; [0004] 2. The precision of the production parts is poor; [0005] 3. There is a lot of waste of raw materials. Contents of the invention [0006] The purpose of the present invention is to provide a washing machine dehydration shaft forming process, which has the characteristics of high production efficiency and saving raw materials, so as to solve the problems existing in the washing machine deh...
