Abstract
The utility model provides a driven angle gear billet rotary floating die structure for finish forging driven angle gear billet, which consists of a toothlike die, a die holder and bolts. The driven angle gear billet rotary floating die structure is characterized in that the toothlike die is arranged on the die holder through the bolts and a rabbet on the die holder. The driven angle gear billet rotary floating die structure has the advantages that the toothlike die of the driven angle gear billet rotary floating die floats circumferentially; and the toothlike die can rotate during working. Therefore, the toothlike die can rotate as parts are formed during the finish forging of driven angle gear billet, which not only brings convenience to the filling and the forming of the toothlike positions of the parts, but also significantly reduces the torque exerted on the toothlike part of the toothlike die, thereby effectively reducing the poor stress of the die and prolonging the service life of the die.
Description
Technical field
The utility model belongs to the Manufacturing Technology for Automotive Parts field, particularly a kind of finish forge driven wheel of differential tooth base rotation floating die assembly structure.
Background technology
The fine forging technology application on auto industry is in the last few years more and more widely especially all being played important effect aspect reducing production costs, improving the quality of products.Driven wheel of differential generally adopts behind the common forging base at present by rough milling and finish-milling (or drawing tooth) the processing flank of tooth.Efficient is lower, and the metal streamline of part is cut off by large tracts of land during owing to machine cutting face, causes part strength to reduce.Gear is prone to " broken teeth " phenomenon in the course of the work.
Adopt the processing method of finish forge profile of tooth to substitute the first processing teeth groove that mills.Not only enhance productivity and part quality, but also can reduce part manufacturing cost.Therefore external, domestic many manufacturing firms develop driven-gear briquette finish forge technology.One of restriction driven-gear briquette finish forge technology key in application factor is that die life is lower, therefore improves will play an important role to applying driven wheel of differential tooth base finish forge technology die life.
Driven tooth gear teeth base finish forge mould tooth die part adopts screw axial to be fixed on the mould bases usually, because parts of tooth is a helical arc umbrella tooth, in the wheel blank precision forging process, blank forms profile of tooth, it is a kind of rotational symmetric peripheral force that the part profile of tooth acts on the tooth die, therefore will form the rotation torque to tooth die.This moment of torsion is very unfavorable to tooth die, has a strong impact on the life-span of mould.
Summary of the invention
The utility model purpose provides a kind of finish forge driven wheel of differential tooth base rotation floating die assembly structure.
The technical solution of the utility model is achieved in that
Finish forge driven wheel of differential tooth base rotation floating die assembly structure is made up of tooth die, die holder and screw, and it is characterized by: tooth die is installed on the die holder by the seam on screw and the die holder.
Advantage of the present utility model is: the tooth die of finish forge driven wheel of differential tooth mold tool circumferentially floats, and can rotate in the tooth die course of work.Tooth die rotates along with part forming in finish forge driven wheel of differential tooth base process like this, not only help filling of part toothed section and add shaping, and the suffered moment of torsion of tooth die toothed area is reduced greatly, can alleviate the abominable stress state of mould effectively, improve the service life of mould.

Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
Finish forge driven wheel of differential tooth base rotation floating die assembly structure is made up of tooth die 1, die holder 2 and screw 3, and it is characterized by: tooth die 1 is installed on the die holder 2 by the seam on screw 3 and the die holder 2.
As shown in Figure 1, finish forge driven wheel of differential tooth base rotation floating die assembly structure, tooth die 1 sidewall processes annular groove along week, processes seam on the die holder 2, and tooth die 1 is installed in the seam of die holder, seam is realized the radial location to tooth die 1, even distribution screw hole on the seam sidewall, on die holder, screw head is processed into spheroidal to screw 3 with tooth die 1 axial location, can realize the axial limiting of tooth die on the top behind the tooth die, tooth die can circumferentially rotate again on die holder.
Embodiment
Certain vehicle bridge main reducing gear driven wheel of differential tooth base finish forge mould tooth die is located at counterdie, cannelure is driven in tooth die sidewall middle part, die holder adopts the radial location mode of seam realization to tooth die, the seam sidewall is opened screwed hole, screw is realized axial location by screwed hole to tooth die, and allows tooth die circumferentially rotatable.
