Abstract

The invention relates to a method for manufacturing a coupler for a distributor of an automobile engine. The method includes following steps of: preparing raw materials, mixing the materials; molding; sintering; shaping, and the like. The beneficial effects of the method are that: the coupler is manufactured by powder metallurgy and has good dimensional uniformity; the assembling difficulty is greatly lightened; the manufacturing cost is reduced; the utilization ratio of the materials is increased; and the manufacturing process is simple and liable for batch production.

Description

The manufacture method of coupler for distributor of automobile engine
Technical field
The present invention relates to a kind of manufacture method of shaft coupling, particularly a kind of manufacture method of coupler for distributor of automobile engine.
Background technology
The shaft coupling of automobile current generator generally adopt iron and steel to process or other technique process, man-hour is added at employing iron and steel, not only manufacturing procedure is longer, and after processing, the utilization ratio of waste material is lower, and the shaft coupling assembly difficulty processed is comparatively large, and cost is higher, be unfavorable for batch production, reduce production efficiency.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of production technique simple, and the manufacture method of the coupler for distributor of automobile engine that can enhance productivity.
Technical scheme: a kind of manufacture method of coupler for distributor of automobile engine, comprises the following steps:
A) get the raw materials ready:
Iron powder 85 ~ 95%,
Nickel powder 5 ~ 8%,
Copper powder 2 ~ 5%,
Graphite Powder 99 0.5 ~ 1.5%,
Lubricant 0.5 ~ 1.2%;
B) batch mixing: by the powder mixing in step a, make the loose density of storeroom be 2 ~ 3g/cm 3, flowing property is less than 40 seconds;
C) suppress: the powder after mixing is loaded in preprepared mould, is pressed into shaft coupling blank on a hydraulic press;
D) sinter: shaft coupling blank is contained in sintering oven, sinters in nitrogen, make shaft coupling blank hardness reach HRB75;
E) shaping: the shaft coupling blank after sintering is put into mould and extrudes;
F) mechanical workout: on lathe, turning is carried out to shaft coupling blank, planar end surface, Drilling operation become shaft coupling finished product.
Wherein, described step is gathered powder mixing employing dry method batch mixing in b and is mixed 30 ~ 60 minutes.
Wherein, described step gathers the pressure of hydropress in c is 450 ~ 500Mpa
Wherein, described lubricant is Zinic stearas.
Beneficial effect: the present invention has good dimensional uniformity by using powder metallurgy to make shaft coupling, reduce the assembly difficulty of shaft coupling, reduce production cost, improve the utilization ratio of material, and manufacturing process is simple, be convenient to batch production.
