The punching mold comprises a punch handle, a positioning seat, a convex die, a concave die, a subplate, a rubber plate and a soleplate, wherein the punch handle is directly connected with a slide block of a worktable on a punching device, the positioning seat, the convex die, the concave die, the subplate, the rubber plate, the soleplate and the positioning plate are connected together to form a lower mold, the concave die is fixedly connected with the subplate and the soleplate, the convex die and the rubber plate are movably connected with the subplate and the soleplate through an unloading screw, a punching cutting edge of the convex die is arranged above a punching cutting edge of the concave die and corresponds to the punching cutting edge of the concave die in the vertical direction, the positioning seat is fixed on the concave die, the lower mold is fixed on a lower working table-board of the punching device, and the punch handle corresponds to the convex die on the lower mold. The punching mold is simple in structure and convenient to operate and can improve the punching machining safety.

Description

A kind of punching die that is used for outer cover class part oral area
Technical field
The present invention relates to a kind of cold punching die, especially a kind of punching die of on punch press, processing outer cover class part oral area hole.
Background technology
The diel in outer cover class part oral area hole at present mostly is traditional upper and lower mould structure, be that punch-die is placed in the fixed head of upper die and lower die, part places on the location-plate on counterdie surface, behind the upper and lower mould matched moulds part punching out is formed, its structure is relatively complicated, and cost of manufacture is higher, when taking part, as maloperation takes place, easily wound causes operating personnel, has potential safety hazard.
Summary of the invention
The objective of the invention is,,, provide a kind of punching die of safe and practical outer cover class part oral area according to the processing characteristic in outer cover class part oral area hole at the problems referred to above.
The present invention adopts following technical proposals:
The described punching die that is used for outer cover class part oral area, comprise punch-holder shank, positioning seat, punch, die, backing plate, rubber slab, base plate, described punch-holder shank directly is connected with the slide block of pressing equipment upper table, described positioning seat, punch, die, backing plate, rubber slab, base plate and location-plate connect to form counterdie, wherein die is fixedlyed connected with base plate with backing plate, punch, rubber slab and backing plate and base plate flexibly connect by the discharging screw, the punching cutting edge of punch is positioned on the die punching cutting edge also corresponding in vertical direction, positioning seat is fixed on the die, counterdie is fixed on the lower table face of pressing equipment, and punch-holder shank is corresponding with the punch on being connected counterdie.
Adopt the punching die of the present invention of said structure, the location of outer cover class part to be processed and punching out are all carried out on counterdie, mould structure is simple, handling safety, easy.
Description of drawings
Fig. 1 is the structural front view that is used for outer cover class part oral area punching die embodiment of the present invention;
Fig. 2 is the vertical view of punching die embodiment shown in Figure 1;
Fig. 3 is the side view of punching die embodiment shown in Figure 1;
Fig. 4 to Fig. 6 is that the outer cover class part master of punching die shown in Figure 1 processing looks, side-looking, vertical view.
Among the figure: 1-punch-holder shank, 2-positioning seat, 3-punch, 4-die, 5-backing plate, 6-rubber slab, 7-base plate, 8-location-plate, 9-lock plug screw.
The specific embodiment
The present invention is described in detail below in conjunction with illustrated embodiment:
As shown in the figure, a kind of outer cover class part oral area is provided with rectangular opening, be suitable for processing by diel, the punching die that is used for this outer cover class part oral area of the present invention comprises punch-holder shank 1, positioning seat 2, punch 3, die 4, backing plate 5, rubber slab 6 and base plate 7, described punch-holder shank 1 directly is connected with the slide block of pressing equipment upper table, described positioning seat 2, punch 3, die 4, backing plate 5, rubber slab 6, base plate 7 and location-plate 8 connect to form counterdie, wherein die 4 is fixedlyed connected with base plate 7 with backing plate 5, punch 3, rubber slab 6 flexibly connects by the discharging screw with backing plate and base plate, punch 3 and die 4 are provided with the punching cutting edge corresponding with the part oral area, the punching cutting edge of punch 3 is positioned on the die 4 punching cutting edges also corresponding in vertical direction, the positioning seat 2 corresponding with part shape links to each other with location-plate 8 and is fixed on the die 4 by the locking plug screw, above-mentioned part connects the lower table face that the counterdie of forming the back is fixed on pressing equipment, and punch-holder shank 1 is corresponding with the punch on being connected counterdie.
For ease of adjusting the position location of part, guarantee the punching precision, described positioning seat 2 sides are provided with location-plate 8, and this location-plate links to each other with positioning seat 2 by locking plug screw 9, so that adjust the position of location-plate relative positioning seat, the degree of depth of control part rectangular opening.Processed outer cover part is represented in double dot dash line among the figure.
The concrete course of work of the present invention is:
Correctly be installed on the punch press and adjust the press closes height, the outer cover part of needs processing is placed on the locating piece 8 and positioning seat that becomes the g6 cooperation with outer cover, after determining accurate positioning, make punch press descending, punch-holder shank presses down punch 3 on the counterdie in the drive of slider of punch, punch 3 moves downwards, need the rectangular opening punching out of punching out to finish outer cover part oral area by effect with die 4 cutting edges, after slider of punch returns, punch 3 turns back to initial position under the effect of rubber slab 6, this moment, positioning seat 2 also played the discharging effect, guaranteed that the outer cover that punching is finished does not deform.Take off the piece test size,, then unclamp locking plug screw 9 as finding that sizing is inaccurate, slowly adjust location-plate 8, after measurement adjustment size is correct, screw the locking plug screw, fix locating piece 8, continue said process, criticize production work normally after the outer cover that examination is gone out is qualified.
The location of Mould Machining part of the present invention and punching are all carried out on counterdie, in the course of work, lead mutually between mould parts die, punch, the positioning seat and guarantee that it has correct relative, reduced the guider of the necessary guide pillar guide pin bushing of conventional punching die structure, in addition, the stressed of mould is directly to be pressed in the punch rear side by punch-holder shank, place, location away from part, punch press and mould do not influence operating personnel when closed and take part, improved the security of punch process, mold integral is simple in structure, has reduced the Mold Making cost.
