Description
Technical field
The utility model belongs to Stamping Die Technology field, more particularly to the beam-like part punching press with anti-rebound drawing bank
Mould.
Background technology
With expanding economy, due to needing to consider that mould needs to shorten the cycle, cost is reduced.Therefore as shape of chinese word Ji beam
Class part, plate is thick, and intensity is high, so part debugging stage progress repeatedly analysis compensation resilience can be caused, causes substantial amounts of add
Work cost.Higher to the planarity requirements of side wall as such part, traditional moulds concave side wall is serious, and the later stage is side wall
The flat substantial amounts of springback compensation of needs is done, greatly increases the difficulty of pincers worker debugging, and the mold use life-span can be greatly reduced.Institute
Invented with this by setting drawing bank, to control the springback capacity of side wall, reduce processing and debugging cost, extend die life.

The groove that should coordinate, set respectively by the concave up drawing for forming shape of chinese word Ji groove on the lower surface of the upper mould insert of groove both sides
Yan Kan, the both sides that corresponding punch insert upper surface is located at lug boss are respectively arranged with and the mating connection of the drawing bank of shape of chinese word Ji groove
Projection, be provided with the material pressing core extended in groove in the vertical holes in groove, the height of lug boss is more than the height of projection, convex
The width in the portion of rising is more than the width of projection.
The groove width of above-mentioned shape of chinese word Ji groove drawing bank is more than or equal to groove depth.
Nitrogen spring is provided between the upper end of above-mentioned material pressing core and upper bolster and material pressing core is driven by nitrogen spring.
When above-mentioned material pressing core moves down into bottom by nitrogen spring driving, the lower end of material pressing core extends the lower end of mould insert
Face.
Above-mentioned punch insert is mounted by means of bolts on die shoe.
Above-mentioned upper mould insert is mounted by means of bolts on upper bolster.
The height of above-mentioned lug boss is equal to the height of groove, and the height of projection is equal to the height of drawing bank.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
1st, the utility model sets and concaves to form shape of chinese word Ji groove respectively on the lower surface of the upper mould insert of groove both sides
Drawing bank, make feature side-wall that plasticity occur again by drawing bank when upper mould insert and punch insert contact moudling part and become
Shape, the resilience of side wall is decreased or even eliminated, the purpose of control part indent is then reached by this forming process, is reduced
Cost, shortens the cycle of mould, while improves quality and the life-span of mould, strengthens the stability of forming parts.

Fig. 1 is sectional view when the utility model part starts shaping.
Fig. 2 is the enlarged drawing in A portions in the utility model Fig. 1.
Fig. 3 is sectional view when part of the present utility model is molded again.
Fig. 4 is the enlarged drawing in B portions in the utility model Fig. 3.
It is upper bolster 1, die shoe 2, upper mould insert 3, material pressing core 4, punch insert 5, lug boss 6, groove 7, drawing bank 8, convex
Block 9, through hole 10, nitrogen spring 11, groove width W, groove depth H.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-4：
Beam-like part diel with anti-rebound drawing bank 8, including upper bolster 1 and die shoe 2, set in upper bolster 1
Mould insert 3 and material pressing core 4 are put, upper mould insert 3 is mounted by means of bolts on upper bolster 1, and punch-pin is set on die shoe 2
Insert 5, punch insert 5 are mounted by means of bolts on die shoe 2, the upper mould insert 3 be provided with punch insert 5
The corresponding matching of lug boss 6 groove 7, be respectively arranged with upward spill on the lower surface of the upper mould insert 3 of the both sides of groove 7
Into the drawing bank 8 of shape of chinese word Ji groove, the groove width W of shape of chinese word Ji groove drawing bank 8 is more than or equal to groove depth H, i.e. drawing bank 8 the ratio of width to height
1 can not be less than：1, so as to ensure the intensity of drawing bank 8；The corresponding upper surface of punch insert 5 is located at the both sides difference of lug boss 6
The projection 9 being connected with the drawing bank 8 of shape of chinese word Ji groove is provided with, is provided with and is extended in groove 7 in the vertical holes in groove 7
Material pressing core 4, the height of lug boss 6 is more than the height of projection 9, and the width of lug boss 6 is more than the width of projection 9；Upper mould insert 3
With making feature side-wall that the resilience that plastic deformation reduces side wall occur again by drawing bank 8 during 5 contact moudling part of punch insert
Deformation reaches the purpose of part indent.
Above-mentioned upper mould insert 3 is provided with through hole 10 in the bottom of groove 7, and the outer end of the material pressing core 4 extends through through hole 10
Is fixedly mounted on the apical grafting of lug boss 6, the inner on upper bolster 1 in groove 7, on the inner end face of material pressing core 4 with upper bolster 1 it
Between be provided with nitrogen spring 11 and material pressing core 4 is driven by nitrogen spring 11；In order to ensure forming parts, material pressing core 4 passes through nitrogen
When the driving of gas spring 11 moves down into bottom, the lower end of material pressing core 4 extends the lower surface of mould insert 3.
The utility model process for stamping comprises the following steps that：
(1) by punch insert by bolt lock on die shoe；
(2) by material pressing core be arranged on upper bolster groove in, by upper mould insert by bolt lock on upper bolster, on composition
Mould；
(3) part (flitch) is placed on the upper surface of punch insert, starts nitrogen spring and drive material pressing core to move down and determine
Position compressing component；
(4) matched moulds, moved down by mould insert in power drive, the lug boss of punch insert coordinates with groove to be started to zero
Part carries out first time shaping, and when upper mould insert moves down into bottom, drawing bank coordinates the lower corner pair in lug boss both sides with projection
Part implements anti-rebound post forming, feature side-wall tensed, be plastically deformed again, decreases or even eliminates returning for side wall
Bullet deforms, and reaches the purpose of control part indent.
(4) mold, upper mould follows lathe sliding block to move up, and completes shaping.
(5) the good stamping parts of step (4) punching press is removed.
Due to the effect of drawing bank and projection, by the stress concentration of punching press on the part at drawing bank and projection, die sinking
Afterwards due to the rebound effect of drawing bank and projection part everywhere so that the part at drawing bank and projection is extended into flat
