Abstract
The invention discloses a molding method of a thickened hub multi-wedge wheel of an automobile crankshaft. The whole machining process is finished by sequentially drawing a cup, reversely drawing a boss, reversely drawing a spherical boss again, shaping fillets, shaping to increase thickness, punching a central hole and spinning a plurality of wedge grooves and patterns on an outer circle. The molding method has the advantages that the hub pattern machining method provided by the invention is more rapid and efficient than traditional pattern spinning and does not need special spinning equipment, so that unnecessary cost is reduced, the quality of products can be improved, and massive production is adapted.
Description
Technical field
The present invention relates to driving engine part processing technique field, particularly a kind of automobile crane thicken many wedge wheels of wheel hub into
Type method.
Background technology
Automobile crane thickens many wedge wheels of wheel hub in processing, and traditional mode is to carry out spinning flower pattern, and the method needs special
Spinning machine, it is relatively costly, and process it is less efficient, be unfavorable for produce in enormous quantities.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided a kind of without the need for special spinning machine, need to only be passed through
Punching press can complete the processing method that automobile crane thickens many wedge wheel shaping method hubs of wheel hub being embossed.
The technical solution used in the present invention is：
A kind of automobile crane thickens many wedge wheel shaping methods of wheel hub, and its innovative point is to comprise the following steps that：
1）Pull into cup-shaped：Steel plate of the thickness for 3mm is pulled into into cup-shaped by stretcher, and the bottom surface of cup-shaped is upward；
2）Reverse-drawing boss：By the bottom surface negative drawing of cup-shaped, bottom surface boss directed downwardly is formed；
3）Negative drawing sphere boss again：By boss bottom surface directed downwardly back towards upper stretching, and form sphere boss；
4）Shaping fillet：The fillet that stretching position is formed is carried out into shaping, quality of production requirement is met；
5）Shaping is thickened：Using particular manufacturing craft, sphere boss height is reduced, while spherical shape is shaped to plane, and makes to put down
Face thickness is thickened as 5mm；
6）Rush centre bore：Plane after shaping is utilized into punching apparatus, centre bore is gone out；
7）The cylindrical multiple wedge slot of spinning：The semi-finished product for punching centre bore are carried out into cylindrical multiple wedge slot processing using spinning machine；
8）Embossing：Planar top after shaping is embossed into processing using special knurling mould, whole process is completed.
Beneficial effects of the present invention are as follows：
The processing method of the wheel hub flower pattern that the present invention is provided, it is more quicker than traditional spinning flower pattern, efficient, without the need for special
Spinning machine, reduces unnecessary cost, and can improve the quality of product, is adapted to batch production.

Specific embodiment
A kind of automobile crane thickens many wedge wheel shaping methods of wheel hub, comprises the following steps that：
1）Pull into cup-shaped：Steel plate of the thickness for 3mm is pulled into into cup-shaped by stretcher, and the bottom surface of cup-shaped is upward, such as Fig. 1；
2）Reverse-drawing boss：By the bottom surface negative drawing of cup-shaped, bottom surface boss directed downwardly, such as Fig. 2 are formed；
3）Negative drawing sphere boss again：By boss bottom surface directed downwardly back towards upper stretching, and form sphere boss, such as Fig. 3；
4）Shaping fillet：The fillet that stretching position is formed is carried out into shaping, quality of production requirement, such as Fig. 4 is met；
5）Shaping is thickened：Using particular manufacturing craft, sphere boss height is reduced, while spherical shape is shaped to plane, and makes to put down
Face thickness is thickened as 5mm, such as Fig. 5；
6）Rush centre bore：Plane after shaping is utilized into punching apparatus, centre bore, such as Fig. 6 is gone out；
7）The cylindrical multiple wedge slot of spinning：The semi-finished product for punching centre bore are carried out into cylindrical multiple wedge slot processing using spinning machine, is such as schemed
7；
8）Embossing：Planar top after shaping is embossed into processing using special knurling mould, whole process is completed,
Such as Fig. 8.
The above is the preferred embodiment of the present invention, it is impossible to the interest field of the present invention is limited with this.Should refer to
Go out, for those skilled in the art, technical scheme is modified or equivalent, all
Without departing from protection scope of the present invention.
