Abstract

The invention discloses a washing machine washing shaft spline extrusion die and an extrusion process thereof. The washing machine washing shaft spline extrusion die is mounted on a punch, and comprises an upper spline extrusion die and a lower spline extrusion die which are arranged oppositely, an upper die cover is fixed on the bottom of the upper spline extrusion die, and a lower die cover is fixed on the top of the lower spline extrusion die. The washing machine washing shaft spline extrusion process includes the following steps: the outer circle parts of the splines of both ends of material and the middle shoulder are extruded to be formed; rough turning or rough grinding is adopted to increase the surface roughness of a workpiece, a layer of lubricating film is attached on the surface of the workpiece, so that the workpiece can be in smooth contact with the die, and the splines are extruded; and the splines of both ends are extruded to be formed by the die in one step. The washing machine washing shaft spline extrusion die and the extrusion process thereof have the advantages that the production efficiency is high, the precision and surface roughness of the produced part are high, and material is saved.

Description

A kind of washing machine wash shaft is squeezed spline mould and extrusion process thereof
Technical field
The present invention relates to the washing machine parts processing technique field, relate in particular to a kind of washing machine wash shaft and squeeze spline mould and extrusion process thereof.
Background technology
At present, the spline of traditional washing machine wash shaft all is to adopt on the Y3608 horizontal hobbing machine to process, and this processing method exists many shortcomings with not enough:
1, production efficiency is low: about 3~5 minutes of need of every processing;
2, the manufactured parts precision is relatively poor: the uniformity of size is poor, variation is big;
3, the surface roughness of manufactured parts is poor: the surface roughness of the flank of tooth can only reach about Ra3.2, and hobboing cutter needs frequent sharpening;
4, labor strength is big: one of the every production of workman just needs clamping once,
5, the part learies is big: because size is unstable, cause learies big.
Summary of the invention
The object of the present invention is to provide a kind of washing machine wash shaft to squeeze spline mould and extrusion process thereof; It has the element precision of production efficiency height, production and surface roughness is high and cost-effective characteristics, to solve the problem that exists in the prior art washing machine wash shaft process.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of washing machine wash shaft is squeezed the spline mould, and it is assemblied on the punch press, comprises the corresponding upper and lower crowded spline mould that is provided with, and the said below of squeezing the spline mould of going up is fixed with upper mould cover, and the said upper fixed of crowded spline mould down has following die cap.
Especially, the said number of teeth that crowded spline mould is 11, and modulus is 1, and pressure angle is 45 °, strides rod apart from 14.210.
Especially, the said number of teeth of crowded spline mould down is 11, and modulus is 1, and pressure angle is 45 °, strides rod apart from 14.210.
A kind of washing machine wash shaft is squeezed spline technology, and it may further comprise the steps:
1) rammer is takeed on, bar contracts: with raw material two ends spline excircle part and middle convex shoulder extrusion modling;
2) appearance and size processing: adopt rough turn or corase grind raising workpiece surface roughness, to satisfy the requirement that mould squeezes tooth;
3) surface lubrication: surface of the work adheres to one deck lubricating film, and it is smooth and easy to let workpiece contact with mould, prolongs die life simultaneously;
4) squeeze spline: utilize mould with an extrusion modling of two ends spline.
Especially, said step 4 adopts the extrusion modling of J21-100 1000kN punch press.
Beneficial effect of the present invention is that compared with prior art said washing machine wash shaft is squeezed the spline mould and extrusion process has the following advantages:
1, production efficiency is high, has improved nearly 30 times than the efficient of gear hobbing;
2, element precision of producing and surface roughness are high, and the workpiece surface roughness of gear hobbing processing can only reach about Ra3.2, and crowded tooth then can reach more than the Ra1.6, and the variation of size is little;
3, the raw material consumption significantly reduces, and provides cost savings.
