The axle housing of such 4 × 2 vehicle drive axle of card is processed into by the thick hot rolled plates of 6.0mm are stamped,
The processing for cutting long trimming multi-station mold can be used for after molding procedure：
The first step, the automobile drive axle housing body of the present invention is cut into long trimming multi-station mold, installed in single-point enclosed
On steam-operating 1600T forcing presses, and control valve 26 and the compressed air interface of lathe are connected.
Second step, as shown in figure 3, the axle housing molding part 19 after molding procedure is placed on into two pieces cuts long cavity plate 21
Cut elongated intracavitary portion and two pieces cuts the upper surface of long locating piece 20；As shown in Fig. 2 cut long part by the axle housing after long process is cut
It is placed on the upper surface of trimming retainer plate 27 and the right side of the right side trimming inner ring locating piece 29 of trimming punch component 9,10,11,12
Side, and axle housing is cut the rear and front end end face of long part and be placed between the inner face of two pieces trimming locating piece 28；One will be cut
The unilateral cut piece of axle housing after the process of side is placed on upper surface and the trimming punch component 9,10,11,12 of trimming retainer plate 27
The left side of left side trimming inner ring locating piece 29, and the rear and front end end face of the unilateral cut piece of axle housing is placed on two pieces trimming
Between the inner face of locating piece 28.
3rd step, the control valve of control valve 26 is opened, clamp four trimmings on left and right sides trimming retainer plate 27
The piston head of cylinder 24 simultaneous ejection, and the axle housing of the left and right sides is cut in the long unilateral cut piece of part and axle housing simultaneously
The outer mold surface of type face and trimming inner ring locating piece 29 is in close contact to form axle housing trimming positioning.
4th step, start forcing press and the long unilateral cut piece of part and axle housing is cut to axle housing molding part 19, axle housing
Punch process is carried out, workbench on lathe, cuts long punch-pin 15, the first trim die component 5, the second trim die component 6, the
Three trim die components 7 and the 4th trim die component 8 move downward, in the process, cut long unloading block 17 at first with axle housing
Then motion upwards is transferred in the contact of body molding part 19, subsequent trim die fixed seat 4 is contacted with upperpush rod 33 and continued downwards
Motion, trimming retainer plate 27 cuts the long unilateral cut piece of part and axle housing with axle housing will be with bearing spring 37 because compression produces
Elastic force moves downward together with it.At the same time, the first to fourth trim die component 5,6,7,8 is cut with axle housing
The long unilateral cut piece of part and axle housing synchronously contacts and continues to move downward, and trimming interfix device cuts long part with axle housing
Elastic force will be produced as it is moved downward together because of compression with connecting rod stage clip 31, with the unilateral cut piece of axle housing until on lathe
Untill workbench runs to bottom dead centre, axle housing molding part 19 is set long punch-pin 15 and to cut long cavity plate 21 in cutting for rear and front end
The both ends end face of axle housing molding part 19 collectively constituted cut elongated intracavitary complete cut length, reach cut the mm of length 1360.4,
