It is put into that plasticity is low and on-deformable material transfer cylinder 8, finally injects preheated solid particle 7.Gland 12 and pressure head 11 are closed.
Applying pressure to gland 12 and pressure head 11 according to certain load path is plastically deformed pipe 2, and pressure head 11 is to solid
Grain 7 applies pressure and pipe 2 is deformed by radial pressure, and gland 12 applies axial compressive force to pipe 2 to make pipe
Base 2 has certain axial displacement in the axial direction, is more advantageous under the comprehensive function of axial feed and radial pressure in this way
Shape.In the process, solid particle 7 is contacted with material transfer cylinder 8 always, avoids axle housing straight-arm part and front and back cover in this way
Divide and is thinned by excessive pressure.With the progress of forming process, solid particle 7 is just constantly corresponding by Chinese lute packet 15
Pipe part squeeze into Chinese lute packet shaping chamber, make under the collective effect of pressure head 11 and gland 12 in this way pipe 2 shape.With back spin
Cut processing reducer shell mounting hole 16 and using heavy wall dome-type part drawing by high temperature technique to the bridge packet 17 of axle housing rear cover into
Row stretch forming.Finally reducing formation formation Automobile drive is carried out far from one end of Chinese lute packet 15 to left straight-arm 5 and right straight-arm 6
The spindle nose part of axle shell.
Q460C high-strength steel sheet pipe 2: mold 1 is first preheated to 2 forming temperature of pipe, 780 DEG C of heating temperature, is added
Hot mode is resistance heating.Solid particle 7 is heated to 700 DEG C of predetermined temperature, solid particle 7 uses furnace external heat.
Pipe 2 is heated to predetermined temperature.Preheated pipe 2 is fitted into the forming cavity of heated mould specific 1, is then placed in low modeling
Property and on-deformable material transfer cylinder 8, finally inject preheated solid particle 7, gland 12 and pressure head 11 are closed.According to certain
Load path pressure applied to pressure head 11 and gland 12 be plastically deformed pipe 2, pressure head 11 applies pressure to solid particle 7
Power makes pipe 2 be deformed by radial pressure, and gland 12 applies axial compressive force to pipe 2 to make pipe 2 in axial direction
There is certain axial displacement in direction, is more advantageous to forming under the comprehensive function of axial feed and radial pressure in this way.It crosses herein
Cheng Zhong, solid particle 7 are contacted with material transfer cylinder 8 always, avoid axle housing straight-arm and corresponding 2 part of pipe of front and rear covers in this way
It is thinned by excessive pressure.With the progress of forming process, solid particle 7 is just constantly corresponding by Chinese lute packet 15
Chinese lute packet shaping chamber is squeezed into pipe part, in this way shapes under the collective effect of pressure head 11 and gland 12 pipe 2.Subsequent rotary-cut
It processes reducer shell mounting hole 16 and is carried out using bridge packet 17 of the heavy wall dome-type part drawing by high temperature technique to axle housing rear cover
Stretch forming.Reducing formation finally is carried out far from one end of Chinese lute packet 15 to left straight-arm 5 and right straight-arm 6 and forms automobile drive axle bridge
The spindle nose part of shell.
It should be noted that two sides are provided with Chinese lute packet 15 up and down in the middle part of existing automobile drive axle housing, front side is provided with
Reducer shell mounting hole 16, rear side are provided with bridge packet 17, and the left and right sides is connect with left straight-arm 5 and right straight-arm 6 respectively；In Fig. 1
Top half is to complete end state, and lower half portion is original state.
Apply that a specific example illustrates the principle and implementation of the invention in this specification, above embodiments
Explanation be merely used to help understand method and its core concept of the invention；At the same time, for those skilled in the art,
According to the thought of the present invention, there will be changes in the specific implementation manner and application range.In conclusion in this specification
