But compared with advanced foreign technology, gap bigger in addition.
Mainly showing as: apparatus and process falls behind, processing automatic capability is low.
In order to closely follow the development of oil engine electrical equipment and electrical industry technology and supporting needs, adapt to volume development need little, lightweight, a kind of new starting engine planetary gear speed reducing mechanism has occurred. Wherein the processing of planet axis is as shown in Figure 1, it is made up of two sections of splines in the middle of planet axis, one section is 10 tooth helical splines, another section is 5 tooth helical splines, can not process during rotary rolling mill simultaneously, and past more original processing mode has first rolled 10 tooth helical splines, milling 5 tooth helical spline on milling machine again, working (machining) efficiency is low, cost height, and within one day, a milling machine can only produce more than 100 in 8 hours. In order to improve working (machining) efficiency, we change processing mode, change punch process into by former Milling Process. It is thus desirable to design the mould device of a set of punching press male spline groove.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that the mould device of a kind of punching press male spline groove, structure is simple, it is possible to improve working (machining) efficiency, reduces tooling cost.
According to technical scheme provided by the invention, the mould device of described punching press male spline groove, comprises drift and mold, it is characterized in that: the bottom of described drift arranges interior hole, and bore surface is the conical surface; Described mold comprises base plate, and plate upper surface fixes die holder, and the center of die holder is provided with circular hole, arranges permanent sleeve above die holder, and the core portion of permanent sleeve is through hole, and this through hole is for placing planet axis; Round ring boss is set in the bottom of described permanent sleeve, the lower surface of round ring boss and the center hole axial location of die holder; Described die holder is along the circumferential direction arranged many groove bodies, groove body and die holder center hole are through, groove body arranges slide block respectively, the outer face of slide block is the circular arc inclined-plane mated mutually with drift bore surface, and the inner face of slide block stretches into the profile of tooth in the circular hole at die holder center, for mating with planet axis spline; It is provided with sulculus in the bottom of described groove body, arranging pin in sulculus, upper end and the slide block of pin are fixed, and arrange spring in sulculus, one end of spring is supported on pin towards die holder center hole side, and the spring the other end is supported on the inwall of sulculus towards die holder center hole side.
Core portion through hole hole wall at described permanent sleeve offers the aperture with ft connection, this aperture arranges steady brace, steady brace the inner is the profile of tooth mated mutually with planet axis tooth spline, outer end and the baffle plate of steady brace are fixed, shoulder it is provided with, sheathed compression spring between shoulder and baffle plate in the middle part of steady brace.
Described base plate is annular.
Described die holder is truncated cone.
Described slide block is elongated.
The mould device of punching press male spline groove of the present invention, structure is simple, it is possible to improve working (machining) efficiency, reduces tooling cost; The present invention improves 35 times than common Milling Process work efficiency, and Milling Process can only produce more than 100 8 hours every days, and can reach more than 3500 with the processing of this device.
