Description
Technical field
The present invention relates to a kind of composite cold stamping mold, particularly relate to the composite die structure of multiple cold stamping operation.
Background technology
The basic technology scheme that is shaped for bottom surface U-shaped bool with holes has three at present:
(1) blanking, bending, the single operation of punching are shaped;
(2) blanking, punching are compound, and crooked more single operation is shaped;
(3) blanking list operation is shaped, crooked again, punching combined shaping.
Scheme (1) mould structure is simple, needs 3 secondary moulds, and efficient and precision are all lower; Scheme (2) and (3) structure are complicated a little, need 2 secondary moulds, and efficient and precision all increase.But these three kinds of schemes can not satisfy the modern production high accuracy far away, low cost, the requirement of high benefit.
Summary of the invention
The purpose of this invention is to provide a kind of mould structure, can satisfy the modern production high accuracy preferably, low cost, the requirement of high benefit.
The present invention is a kind of composite cold stamping mold structure, comprise upper die and lower die two parts, patrix by upper bolster 1, discharging screw 2, backing plate 3, die shank 4, screw 5, guide pillar 6, screw 7, pin 8, punch-die 9, stripper 10, angled slide block 23, spring 25, spring 26, backing-out punch 27, guide pin bushing 28 form, spring 29 is formed, wherein punch-die 9 and guide pillar 6 be installed in upper bolster respectively 1 time, angled slide block 23 and backing-out punch 27 is installed in 9 li of punch-dies, guide pin bushing 28 is directly installed on upper bolster 1 time.
Counterdie by die 11, top board 12, screw 13, alignment pin 14, die shoe 15, fixed head 16, stop screw 17, punch 18, pressure pin 19, head part spring 20, crooked punch 21, guide pillar 22, pin stop 24 form, wherein guide pillar 22 is directly installed on the die shoe 15, die 11 is directly installed on the die shoe 15, punch 18 and crooked punch 21 are installed in 11 li of dies.Counterdie is by guide pillar 22 and guide pin bushing 28 and Ccope closing machine.
Usefulness of the present invention
U-shaped bool forming technology scheme for bottom of which has holes can make blanking, bending and punching combined shaping, this scheme only needs 1 secondary mould, mould structure is also uncomplicated, precision and efficient are all higher, so its core technology designs blanking exactly, and crooked and punching hole composite die structure, promptly blanking is decomposed into and cuts tongue and cut-out, tongue, bending, punching, cut-out compound die are cut in design.
Description of drawings
Fig. 1 is the die structure dwg of the embodiment of the invention, and Reference numeral and corresponding name are called:
Upper bolster 1, discharging screw 2, backing plate 3, die shank 4, screw 5, guide pillar 6, screw 7, pin 8, punch-die 9, stripper 10, die 11, top board 12, screw 13, alignment pin 14, die shoe 15, fixed head 16, stop screw 17, punch 18, pressure pin 19, spring 20, crooked punch 21, guide pillar 22, angled slide block 23, pin stop 24, spring 25, spring 26, backing-out punch 27, guide pin bushing 28, spring 29.
The specific embodiment
As shown in Figure 1, composite cold stamping mold of the present invention comprises upper die and lower die two parts.Patrix by upper bolster 1, by the locating hole and first screw 5 be directly installed on center on the upper bolster 1 die shank 4, by locating hole and backing plate 3 and screw 7 and pin 8 be installed in guide pin bushing 28, guide pillar 6, punch-die 9, the spring 25 that is installed in 9 li of punch-dies, spring 26 and backing-out punch 27 under the upper bolster 1 and angled slide block 23 respectively, the stripper 10 that is installed in around 1 time punch-die of upper bolster 9 by discharging screw 2 and discharging spring 29 forms; Backing-out punch 27 double as cut off punch and punching concave die, are led by guide pillar 6.Counterdie is by die shoe 15, be directly installed on guide pillar 22 on the die shoe 15 by locating hole, be installed in the die 11 in die shoe 15 centres by screw 13 and alignment pin 14, be installed in the crooked punch 21 of 11 li of dies by stop screw 17, be installed in the fixed head 16 and the punch 18 of 11 li of dies by locating hole and pressure shoulder, be installed in spring 20 and top board 12 between die 11 and the crooked punch 21, be directly installed on the pin stop 24 on the die 11, the pressure pin 19 that is installed in 15 li of die shoes is formed, crooked punch 21 is movable.Patrix is by guide pin bushing 28 and guide pillar 22 and counterdie matched moulds.
It is 1-10 that the slide block (not shown) of forcing press drives by Reference numeral among Fig. 1,23, the patrix that 25-29 forms moves downward, stripper 10 and backing-out punch 27 and angled slide block 23 at first touch the blank upper surface that is placed on die 11 and the crooked punch 21 it are compressed, patrix continues that descending to be that punch-die 9 moves downward about 1.5 material thick, finishes and cuts tongue; Punch-die 9 continues descendingly to begin to be bent to that to finish bending be the upper surface that backing plate 3 lower surfaces touch backing-out punch 27, act on power crooked punch 21 on greater than spring 25 and spring 26 by backing-out punch 27 and blank in the power on the crooked punch 21 in stop screw 17 and pressure pin 19 actings in conjunction before this, so crooked punch 21 does not move; Patrix continues descending, because backing plate 3 lower surfaces are that rigidity contacts with the upper surface of backing-out punch 27, and the active force of pressure pin 19 is an elastic force, and backing-out punch 27 contacts with fixed head 16 upper surfaces with the lower surface that crooked punch 21 moves downward crooked punch 21 simultaneously like this, finishes and cuts off and punching.Press ram arrives bottom dead centre; forcing press drives the patrix backhaul; mainly finish the discharging of waste material and blank, finish ejecting of workpiece by head part spring 20 and top board 12 and spring 26 and backing-out punch 27 by discharging spring 29 and stripper 10 and spring 25 and angled slide block 23.
