Description
Technical field
The present invention relates to a kind of whole composite die in flange side, belong to automobile stamping field.
Background technology
Automobile industry is improved constantly to the Material Strength of stamping parts, and quality requirements also more and more higher, stamping parts qualification rate is needed
More than or equal to 95%, flange resilience is out-of-size main cause, and solving flange resilience has two kinds of approach：One is in flange
Operation adjusts resilience, and specific method exists《Practical Punch Parts technical manual》In be all described, as amendment punch angle compensate,
Made on punch-pin and being compensated equal to the gradient of springback angle, required angle is exactly equal to after making product resilience；Two is to increase
Side trimming adjustment resilience.First method disposably can not just obtain qualified products, it is sometimes necessary to which debugging is multiple,
Adjustment cycle schedule delays long and cost is increased, second method needs to increase a set of side shaping mould, increases die cost
Increase cost of stamping.
In addition, general side mould preparation material pressing body is placed in mould, pressure source is done using nitrogen spring, pressure is non-adjustable.
The content of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, there is provided one kind ensure that product quality, and simplify work
The whole composite die in flange side of skill.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of whole composite die in flange side, including upper die body
And the lower mold body corresponding with the upper die body, the upper die body include upper bolster, wedge drive block and punch insert, it is described on
The lower end of die holder is symmetrically installed with two wedge drive blocks and a punch insert, and the punch insert is arranged on two
Between the individual wedge drive block；The lower mold body includes die shoe, wedge and material pressing body, and two are provided with the die shoe
The wedge that can be slid laterally and a material pressing body corresponding with the punch insert, on the inclined-plane of the wedge
Guide pad is provided with, non-inclined-plane is provided with die plate insert, and the lower end of the material pressing body is connected with the push rod through the die shoe, institute
Stating push rod can be moved up and down, and stopping means is provided between the material pressing body and the die shoe.
Further, the push rod is connected with the air cushion of the press.
Further, the lower surface of the wedge drive block is inclined-plane, and is adapted with the inclined-plane of the wedge.
The beneficial effects of the invention are as follows：The whole operation of traditional overturning process and side is compound in one set of die, Ke Yi
On the premise of ensureing product quality, simplify forming technology, reduce the expenses such as mold design, production.

Specific embodiment
Principle of the invention and feature are described below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
It is non-for limiting the scope of the present invention.
As shown in figure 1, a kind of whole composite die in flange side, including upper die body and the lower mould corresponding with the upper die body
Body, the upper die body includes upper bolster 2, wedge drive block 5 and punch insert 4, and the upper bolster 2 is arranged on press upper table
On, the lower end of the upper bolster 2 is provided with two wedge drive blocks 5 and a punch insert 4, and the punch insert 4 sets
Put between two wedge drive blocks 5；The lower mold body includes die shoe 1, wedge 7 and material pressing body 3, the die shoe 1
On the lower table of press, be provided with the die shoe 1 two wedges 7 that can be slid laterally and one with it is described
The corresponding material pressing body 3 of punch insert 4, the inclined-plane of the wedge 7 is provided with guide pad, and non-inclined-plane is provided with die plate insert 6, institute
The lower end for stating material pressing body 3 is connected with push rod 8 through the die shoe, and the push rod 8 can be moved up and down, the push rod 8 and institute
State the air cushion connection of press, the air cushion power produced by press air cushion drives push rod 8 to move up and down, the material pressing body 3 with it is described
Stopping means 9 is provided between die shoe 1, the lower surface of the wedge drive block 5 is inclined-plane, and the inclined-plane with the wedge 7 is mutually fitted
Match somebody with somebody.
The course of work of the invention is as follows：
(1) mould is loaded on press on request, after starting press upper and lower mould point mould, adjusts the air cushion ejecting force of press, if
A fixed provisional value；
(2) the air cushion ejection button of press is started, power is acted on push rod 8, heads on material pressing body 3 and rise to top dead-centre by air cushion
Position, plate is positioned on the upper surface of material pressing body；
(3) press matched moulds is started, upper mould is descending, the contact plate of punch insert 4 heads on material pressing body 3 and enters female die embedding together
Block, starts flanging forming, and now the whole wedge in side is not started working；
(4) when operation is to away from bottom dead centre 5mm, the guide pad in the contact wedge slide block 7 of wedge drive block 5, the whole wedge in side
Start working, side stroke 5mm；
(5) upper bolster is run to lower point, and shaping terminates.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all it is of the invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
