Description
Technical field
The invention belongs to machining equipment field, is related to a kind of axle housing mould, more particularly to a kind of automobile
The body formed mould of Drive axle housing sheet.
Background technology
The effect of automobile drive axle housing body is to support and protect main reducing gear, differential mechanism and semiaxis etc..Meanwhile it is also
It is the chief component of running gear, has and propons（Driven bridge）The quality of automobile is born together and in running car,
Each torque to when counter-force, moment of flexure and braking that driving wheel transmits is born, and the functions such as vehicle frame are transmitted to by suspension.Automobile drive
Axle shell body can be divided into banjo axle and the class of separable housing two from structure.To adapt to bear driving wheel under different loads
Torque, the obform body that it is in variable cross-section from both ends to center that the profile of banjo axle, which is typically, it often uses upper and lower two
The mode of part axle housing splicing butt welding is made.
The traditional mode of production of axle housing is that point six procedures are processed, and it first implements process using single-point plate shearing machine
One blanking is processed, and secondly implements the processing of the blanking of process two using single-point enclosed steam-operating forcing press, then using single-point Closed Hydraulic
Machine implements the processing and forming of process three, then implements process four using single-point enclosed steam-operating forcing press and cuts long processing, moreover using single
Point enclosed steam-operating forcing press implements the trimming of process five processing, and finally implementing process six using radial drilling machine drills（Tapping）Processing.
Using traditional processing technology, its molding procedure using open molding structure mould generally because causing axle housing blank to be molded
Process is not sufficiently stable, and the pipe of especially its two-end part is dehisced, and size is whard to control, the flatness at the large flange of middle part
It is deteriorated larger；And because workpiece loading or unloading operation is more difficult, discharging operation is not smooth enough, causes the process exception that discharges, cause to produce
Less efficient, production is time-consuming longer.
The present invention is based on existing for production technology in the prior art optimization property and considered, design a kind of axle housing into
Pattern has, and can not only make axle housing blank forming process stable, and product discharge process can be made smooth, so by setting

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 of mould can be used for after blanking process：
The first step, by automobile drive axle housing this forming die of the present invention, installed in single-point enclosed 1000T hydraulic presses
On.
Second step, the liftout tank of hydraulic press is reached to the position of its stroke minimum point, then feeding push rod 23 is put into lower mould
In via among plate 18 and the upper plane of feeding push rod 23 is less than the upper plane of lower template 18, then put feeding jacking block 24
Enter in the via among die fixed seat 15.
3rd step, as shown in Fig. 2 by the axle housing blank after blanking process be placed on four groups of cavity plate groups 19,20,
21st, 22 top, and the left and right ends end of axle housing blank is individually positioned in same one end two pieces end locating piece 13
Centre and make its middle part rear end end face nestle up interfix block 8.
4th step, start forcing press and punch process is carried out to axle housing blank, workbench, the first punch-pin on lathe
The 4, second punch set 5 of group, the 3rd punch set 6 and the 4th punch set 7 move downward, when the 4th punch set 7 and axle housing blanking
Axle housing blank starts to produce elastic deformation, as workbench further moves downward on lathe, axle housing when part contacts
Body blank progressively with the 4th cavity plate group 22, bottom discharge push rod 16, the first punch set 4, the second punch set 5, the 3rd punch set
6th, insert 14, the first cavity plate group 19, the second cavity plate group 20, the 3rd cavity plate group 21 and feeding jacking block 24 are in contact, at the same time, under
Discharging push rod 16 moves downwardly together with bottom discharge spring 17 because compressing upward thrust, until workbench is run on lathe
Untill bottom dead centre, then to the pressurize of lathe master cylinder be delayed 2 to 3 seconds, make axle housing 25 four groups of punch sets 4,5,6,7, four groups
Shaping is completed in the forming recess that cavity plate group 19,20,21,22 and feeding jacking block 24 collectively constitute, reaches shaping length 1386.7
Mm, both ends end dehisce the mm of width 70.4 in the range of the mm of φ 75.6, flange face φ 250 broad in the middle, the mm of flatness 1.2, in
Between the mm of large flange circular arc R 125.3, the middle mm of variable cross-section length 390.5, middle large flange extreme higher position and straight type pipe highest
The mm of difference in height 88.2 between position, after overmolding, the structure and size of workpiece are as shown in Figure 3, Figure 4.
5th step, workbench, the first punch set 4, the second punch set 5, the 3rd punch set 6 and the 4th punch set on lathe
7 upward returns, then the liftout tank of hydraulic press is reached to the position of its stroke peak, make feeding push rod 23 by feeding jacking block 24
And axle housing 25 jacks up upwards, at the same time, bottom discharge push rod 16 is with bottom discharge spring 17 because compressing upward thrust one
Rise upwards motion, and make axle housing 25 depart from die fixed seat 15 inner chamber untill.
6th step, take out axle housing 25 with hand and load in body feed tank, restart jacking cylinder of hydraulic press reset, make feeding top
Bar 23 takes back feeding jacking block 24 inner chamber of die fixed seat 15.
The axle housing appearance and size that is made using automobile drive axle housing this forming die of the present invention it is stable into
The mm of type length 1386.7, both ends end dehisce the mm of width 70.4 in the range of the mm of φ 75.6, flange face φ 250 broad in the middle, flat
The mm of face degree 1.2, flange circular arc R125.3 mm broad in the middle, the middle mm of variable cross-section length 390.5, middle large flange extreme higher position
The mm of difference in height 88.2 between straight type pipe extreme higher position, the uniformity of monnolithic case is regular, and sustainable stabilization ensures bridge
The appearance and size of shell body reaches the design requirement of product drawing.Production capacity is also improved while product quality is improved, a card 4
The shaping of the axle housing molding procedure of × 2 vehicle drive axles its blank and discharging process are very smooth and stably, and mould
Tool maintenance frequency significantly reduces.Single products split run production capacity is promoted to 1250 by 970, and split run production capacity improves 28.9%.
