Description
Technical field
A kind of whole composite die in flange side is the utility model is related to, belongs to automobile stamping field.
Background technology
Automobile industry improves constantly to the Material Strength of stamping parts, and also more and more higher, stamping parts qualification rate need quality requirements
More than or equal to 95%, the main reason for flange resilience is off-dimension, solving flange resilience has two kinds of approach：First, in flange
Process adjusts resilience, and specific method exists《Practical Punch Parts technical manual》In be all described, as amendment punch angle compensate,
The gradient made on punch-pin equal to springback angle is compensated, and required angle is exactly equal to after making product resilience；Second, increase
Side trimming adjustment resilience.First method disposably can not just obtain qualified products, it is sometimes necessary to and debugging is multiple,
Adjust cycle long schedule delays and add cost, second method needs to increase a set of side shaping mould, increases die cost
Increase cost of stamping.
In addition, in general side mould preparation material pressing body is placed in mould, pressure source is done using nitrogen spring, pressure is non-adjustable.
Utility model content
The utility model is directed to above-mentioned the deficiencies in the prior art, there is provided one kind can ensure product quality, and letter
The whole composite die in flange side of chemical industry skill.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of whole composite die in flange side, including it is 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, institute
The lower end for stating upper bolster is symmetrically installed with two wedge drive blocks and a punch insert, and the punch insert is set
Between two wedge drive blocks；The lower mold body includes die shoe, wedge and material pressing body, is provided with the die shoe
Two wedges that can be slid laterally and a material pressing body corresponding with the punch insert, the wedge it is oblique
Face is provided with guide pad, and non-inclined-plane is provided with die plate insert, and the lower end of the material pressing body is connected with through the top of the die shoe
Bar, the 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 utility model are：The whole process of traditional overturning process and side is combined in one set of die, can
On the premise of product quality is ensured, to simplify forming technology, the expenses such as mold design, production are reduced.
Brief description of the drawings

Fig. 2 is upper die body structural representation in the utility model；
Fig. 3 is lower mold body structural representation in the utility model；
In the accompanying drawings, the list of designations represented by each label is as follows：1st, die shoe, 2, upper bolster, 3, material pressing body, 4,
Punch insert, 5, wedge drive block, 6, die plate insert, 7, wedge, 8, push rod, 9, stopping means, 10, guide plate.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
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 include 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 is set
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 that can be slid laterally 7 and one with it is described
The corresponding material pressing body 3 of punch insert 4, the inclined-plane of the wedge 7 are 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 move up and down, the push rod 8 and institute
State press air cushion connection, as caused by press air cushion air cushion power drive push rod 8 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, is mutually fitted with the inclined-plane of the wedge 7
Match somebody with somebody.
The course of work of the present utility model is as follows：
(1) mould adjusts the air cushion ejecting force of press on request loaded on press, starting after press upper and lower mould divides mould, 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, and punch insert 4 contacts plate, heads on material pressing body 3 together and enters female die embedding
Block, start flanging forming, now the whole wedge in side is not started working；
(4) when operation is to away from bottom dead centre 5mm, wedge drive block 5 contacts the guide pad in wedge slide block 7, the whole wedge in side
Start working, side stroke 5mm；
(5) upper bolster runs to lower point, shaping and terminated.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
