The Automobile drive rear axle oil baffle punching and blanking progressive die of the utility model is mounted on single-point and opened by the first step
On formula steam-operating 100T press machine.
Oil baffle blank 22 is lain in a horizontal plane in blanking and punching cutting compound concave die 11 and starting point retainer plate 21 by second step
Upper surface on, make oil baffle blank 22 left side and stock guide 23 right side be in close contact, the right side of oil baffle blank 22
With the left close contact of lateral ejection block 20, under the action of ejection block spring 19, lateral ejection block 20 is outside because of compressive deformation
It is even closer that thrust allows oil baffle blank 22 to contact with stock guide 23, moves oil baffle blank 22 further along, makes oil baffle
The front end face of blank 22 and the rear end face of lateral incision block 15 are in close contact, and complete lateral incision positioning；
Third step starts press machine and carries out punch process to oil baffle blank 22, on press machine workbench and upper mold to
Lower movement, in the process, loading and unloading material plate 9 is contacted with oil baffle blank 22 first, then lateral incision punch-pin 17 and oil baffle blank
22 contact and continue to move downward, and until workbench runs to bottom dead centre on lathe, make oil baffle blank 22 in lateral incision
The first work step lateral incision oil baffle blank 22 is completed under the action of between punch-pin 17 and blanking and punching cutting compound concave die 11；Current work
OP1O in program process status such as Fig. 5（First station）It is shown；
4th step, then oil baffle blank 22 is promoted forwards and is by workbench and the upward return of upper mold on press machine：
Make on oil baffle blank 22 it is machined go out oriented side trimming part enter the left side of lateral incision block 15 and stock guide 23 right side it
Between positioning in the locating mould cavity that constitutes, and make the front end of the oil baffle blank 22 without lateral incision and the rear end face of lateral incision block 15
It is in close contact, at the same time, lateral incision leftover pieces 16, which fall to fall into from mold and lathe material spilling hole, is placed on giving up below lathe
In hopper；
5th step starts press machine and carries out punch process again to oil baffle blank 22, workbench and upper mold on press machine
It moves downward, in the process, loading and unloading material plate 9 is contacted with oil baffle blank 22 first, then lateral incision punch-pin 17 and three punchings
Punch-pin 6 successively contacts with oil baffle blank 22 and continues to move downward, until workbench runs to bottom dead centre on lathe,
Complete oil baffle blank 22 under the action of lateral incision punch-pin 17, piercing punch 6 and blanking and punching are cut off between compound concave die 11
First work step lateral incision oil baffle blank 22 and the second work step rush three fixed step pitch holes, current process process status such as Fig. 5
Middle OP2O（Second station）It is shown.
6th step, workbench and the upward return of upper mold on press machine, then oil baffle blank 22 is promoted, make forwards
What the part of the machined side of positioning out went successively to constitute between lateral incision block 15 and stock guide 23 on oil baffle blank 22 determines
Bit-type is intracavitary, and is in close contact the front end of the oil baffle blank 22 without lateral incision and the rear end face of lateral incision block 15, with this
Meanwhile lateral incision leftover pieces 16 and punched scrap fall the ash can for falling into and being placed below lathe from mold and lathe material spilling hole
It is interior；
7th step starts press machine and carries out punch process again to oil baffle blank 22, workbench and upper mold on press machine
It moves downward, in the process, loading and unloading material plate 9 is contacted with oil baffle blank 22 first, then 17, three punching convexes of lateral incision punch-pin
Mould 6 and blanking punch 8 successively contact with oil baffle blank 22 and continue to move downward, until workbench is run to down on lathe
Until dead point, oil baffle blank 22 is made to cut off compound concave die in lateral incision punch-pin 17, piercing punch 6, blanking punch 8 and blanking and punching
The first work step lateral incision oil baffle blank 22 is completed under the action of between 11, the second work step rushes three fixed step pitch holes and third work step
The blanking forming punching of product；Oil baffle 14 after molding requires to reach 46.1 mm of length, 52.6 mm of width, shape circular arc
R8.0 mm, R5.5 mm, installation 6.1 mm of bore inner diameter φ, 35.1 mm of pitch of holes, 41.5 mm, 2.6 mm, hole back gauge 5.5
Mm, after punching and blanking, the structure of workpiece is as shown in Figure 3, Figure 4, OP3O in current process process status such as Fig. 5
（3rd station）It is shown.
8th step, workbench and the upward return of upper mold on press machine, then oil baffle blank 22 is promoted, make forwards
What the part of the machined side of positioning out went successively to constitute between lateral incision block 15 and stock guide 23 on oil baffle blank 22 determines
Bit-type is intracavitary, and at the same time, lateral incision leftover pieces 16 and punched scrap and oil baffle 14 decline from mold and lathe material spilling hole simultaneously
It falls into down and respectively in the ash can and body feed tank being placed below lathe.
The oil baffle shape ruler made of the Automobile drive rear axle oil baffle punching and blanking progressive die of the utility model
Very little stabilization is in 46.1 mm of length, 52.6 mm of width, 8.0 mm of shape circular arc R, R5.5 mm, installation bore inner diameter φ 6.1
Mm, 35.1 mm of pitch of holes, 41.5 mm, 2.6 mm, 5.5 mm of hole back gauge, the consistency of product monnolithic case is regular, can hold
Continuing stable ensures that the outer dimension of oil baffle reaches the design requirement of product drawing.It is also promoted while improving product quality
Production capacity drives the oil baffle production process of rear-end gear reduction very smooth and stablizes, and the punching and blanking progressive die
The maintenance frequency significantly reduces than the mold repair frequency of traditional handicraft, and die life is promoted significant.Single products split run production capacity
11000 are promoted to by 6500, split run production capacity improves 69.2%.
