Problems solved by technology

[0002] At present, the clutch shaft bushing of the pulsator-type automatic washing machine is usually processed by mechanical drilling and cutting, which has low working efficiency and high manufacturing cost. Due to the margin generated by drilling and cutting, it not only wastes materials, but also greatly Reduce the mechanical properties of parts, resulting in short product life

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the drawings and embodiments.

[0020] Such as Figure 1 to Figure 6 As shown, the cold heading extrusion forming method of the clutch shaft sleeve of the pulsator-type automatic washing machine, the shaft sleeve 1 includes a shaft sleeve 2 and a base 3 arranged at the bottom end of the shaft sleeve 2, and the shaft sleeve 2 and the base 3 are formed Integral shape, and the inner cavity 4 of the shaft sleeve 2 is communicated with the base 3. The cold heading extrusion forming method of the sleeve 1 is as follows:

[0021] Step 1. Prepare the cylindrical blank 5 according to the design requirements for use;

[0022] Step two, feed the blank into the first mold 6, according to the set requirements, one end is upset and chamfered, the upsetting rod 7 upsets a counterbore in the middle of the blank end surface in a vertical direction, and the middle part of the inner chamfer plane is fixed with another On...

Abstract

The invention relates to a cold heading extrusion forming processing method for a shaft sleeve of a clutch shaft of an impeller type full-automatic washing machine. The shaft sleeve comprises a shaft sleeve tube and a base, wherein the base is arranged at the bottom end of the shaft sleeve tube, the shaft sleeve tube and the base are in an integrated shape, and an inner cavity of the shaft sleeve tube is communicated with the base. The cold heading extrusion forming processing method for the shaft sleeve overcomes defects of single cold heading or warm heading and then mechanical cutting in the traditional process, the shaft sleeve of the clutch shaft is manufactured through applying the advanced cold heading extrusion forming technique, the cutting allowance of mechanical processing can be reduced when the manufactured shaft sleeve of the clutch shaft is mechanically processed, in particular the process step of drilling middle holes is cancelled so that the cutting time of post processing is greatly reduced, the work efficiency is improved, the cost is lowered, raw materials are saved, the mechanical property of parts is synchronously enhanced through cold heading extrusion forming, and the service life of a product is prolonged.

Description

Technical field [0001] The invention relates to a cold heading extrusion forming method for a clutch shaft sleeve, in particular to a cold heading extrusion forming method for a clutch shaft sleeve of a pulsator-type automatic washing machine. The shaft sleeve is particularly suitable for a pulsator-type automatic washing machine, etc. product. Background technique [0002] At present, the clutch shaft sleeve of the pulsator-type fully automatic washing machine is usually processed by mechanical drilling and cutting processes. The work efficiency is low, and the manufacturing cost is high. Because the drilling and cutting will produce a margin, it not only wastes materials, but also greatly The mechanical properties of the parts are reduced, resulting in a short product life. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and to provide a pulsator type that can not only ensure that the clutc...
