The operation principle of the present embodiment is summarized as follows:
The axle housing of such card 4 × 2 vehicle drive axles is to be processed into by the hot rolled plate that 6.0mm is thick is stamped,
Just the processing of mould is can be used for after blanking operation:
The first step, by this forming die of automobile drive axle housing of the present embodiment, is arranged on single-point enclosed 1000T hydraulic pressure
On machine.
Second step, reaches the liftout tank of hydraulic press the position of its stroke minimum point, then feeding push rod 23 is put into lower mold
In via in the middle of plate 18 and make the upper plane upper plane less than lower bolster 18 of feeding push rod 23, then feeding jacking block 24 is put
Enter in the via in the middle of recessed model fixing seat 15.
3rd step, as in figure 2 it is shown, the axle housing blank after blanking operation is placed on four groups of die groups 19,20,
21, the top of 22, and make the end, two ends, left and right of axle housing blank be individually positioned in two pieces end, same one end locating piece 13
Centre and make rear end end face in the middle part of it nestle up interfix block 8.
4th step, starts forcing press and axle housing blank is carried out punch process, work platforms, the first punch on lathe
Group the 4, second punch set the 5, the 3rd punch set 6 and the 4th punch set 7 move downward, when the 4th punch set 7 and axle housing blanking
During part contact, axle housing blank starts to produce elastic deformation, along with on lathe, work platforms moves further downward, and axle housing
Body blank progressively with the 4th die group 22, bottom discharge push rod the 16, first punch set the 4, second punch set the 5, the 3rd punch set
6, insert the 14, first die group the 19, second die group the 20, the 3rd die group 21 and feeding jacking block 24 contact, meanwhile, under
Discharging push rod 16 moves because of the thrust compressed upwards downwardly together with bottom discharge spring 17, until work platforms runs on lathe
To bottom dead centre, then to lathe master cylinder pressurize time delay 2 to 3 seconds, make axle housing 25 four groups of punch set 4,5,6,7, four groups
Complete molding in the forming recess that die group 19,20,21,22 and feeding jacking block 24 collectively constitute, reach molding length 1386.7
Mm, end, two ends dehisce width 70.4 mm in the range of φ 75.6 mm, flange face φ 250 broad in the middle, flatness 1.2 mm, in
Between large flange circular arc R 125.3 mm, middle variable cross-section length 390.5 mm, flange extreme higher position broad in the middle the highest with straight type pipe
Difference in height 88.2 mm between position, after overmolding, the structure of workpiece is as shown in Figure 3, Figure 4.
5th step, work platforms, the first punch set the 4, second punch set the 5, the 3rd punch set 6 and the 4th punch set on lathe
7 upwards returns, then reach the liftout tank of hydraulic press the position of its stroke peak, make feeding push rod 23 by feeding jacking block 24
And axle housing 25 upwards jack-up, meanwhile, bottom discharge push rod 16 with bottom discharge spring 17 because of compression thrust one upwards
Rise and move upward, and till making axle housing 25 depart from the inner chamber of recessed model fixing seat 15.
6th step, takes out axle housing 25 with hands and loads in body feed tank, restarts jacking cylinder of hydraulic press and resets, makes feeding top
Feeding jacking block 24 is taken back the inner chamber of recessed model fixing seat 15 by bar 23.
The axle housing overall dimensions of employing the present embodiment making is stable to be opened in molding length 1386.7 mm, end, two ends
Width 70.4 mm in the range of mouth φ 75.6 mm, flange face φ 250 broad in the middle, flatness 1.2 mm, flange circular arc broad in the middle
Height between R125.3 mm, middle variable cross-section length 390.5 mm, flange extreme higher position broad in the middle and straight type pipe extreme higher position
Degree differs from 88.2 mm, and the concordance of monnolithic case is regular, and the sustainable stable overall dimensions guaranteeing axle housing reaches product figure
The design requirement of paper.Also improving production capacity while improving product quality, the axle housing of card 4 × 2 vehicle drive axle becomes
Its blank molding of type operation and discharging process is the most smooth and easy and stable, and mold repair number of times significantly reduces.Single-piece is produced
Product split run production capacity is promoted to 1250 by 970, and split run production capacity improves 28.9%.
