Abstract

The invention relates to an inverse punching and blanking die and relates to a stamping die. The inverse punching and blanking die comprises an upper die base, a lower die base, a die handle, a guide sleeve and a guide post, wherein a male and female die is arranged on the upper surface of the lower die base; a punching profile hole is formed in the male and female die; an unloading plate is sleeved on the male and female die and is moveably connected with the lower die base through an unloading screw; a rubber cushion is arranged between the unloading plate and the lower die base; a blanking female die is arranged on the lower surface of the upper die base; a female die hole is formed in the lower surface of the blanking female die; the position of the female die hole corresponds to the male and female die; a punching male die matched with the punching profile hole is arranged in the female die hole; a workpiece jacking device is arranged on the punching male die. Blanking and punching of a workpiece can be finished in one set of die, so that the production efficiency is improved, the workpiece is prevented from being repeatedly positioned, and the product precision is improved.

Description

Flip-over type piercing and blanking die
Technical field
The present invention relates to a kind of diel, relate in particular to a kind of flip-over type piercing and blanking die.
Background technology
Punching press, is at room temperature to utilize the mould being arranged on forcing press to exert pressure to material, makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.Diel is the requisite technological equipment of punching production, is technology-intensive product, and it can carry out the processing and forming such as punching, blanking, bending and pull and stretch.The quality of stamping parts, production efficiency and production cost etc., have direct relation with Design of Dies and manufacture.In punch process, usually need punching after material strip blanking, use existing mould to need first in blanking die, by workpiece blanking, then to put into perforating die punching, operation is many like this, production efficiency is low, and workpiece needs resetting in addition, has affected precision and the quality of product.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of flip-over type piercing and blanking die, can in a mold, complete blanking and the punching of workpiece, has improved production efficiency, has avoided workpiece resetting, has improved Product Precision.
Technical scheme of the present invention is: a kind of flip-over type piercing and blanking die, comprise upper bolster, die shoe, die shank, guide pin bushing and guide pillar, die shoe upper surface is provided with punch-die, on punch-die, have punching hole type hole, punch-die is socketed with stripper outward, stripper is flexibly connected with die shoe by unloading bolt, between stripper and die shoe, be provided with rubber blanket, upper bolster lower surface is provided with blanking die, blanking die lower surface has die hole, the position of die hole is corresponding with punch-die, in die hole, be provided with the piercing punch coordinating with punching hole type hole, on piercing punch, be provided with head part device.
As preferably, die hole is up big and down small shoulder hole, piercing punch is socketed with ejector outward, ejector sidewall is provided with boss, and ejector upper end is connected with push rod, and push rod upper end is connected with push pedal, push pedal is movably connected in upper bolster, push pedal upper end with make bar and be connected, make bar and be movably connected in die shank, beat the upper end of bar and stretch out die shank and be socketed with nut.
As preferably, punch-die is connected with die shoe by bottom plate, and rubber blanket, between stripper and bottom plate, is provided with lower bolster between punch-die and die shoe, blanking die is connected with upper bolster by upper mounted plate, between blanking die and upper bolster, is provided with upper padding plate.
The invention has the beneficial effects as follows: on punch-die of the present invention, have punching hole type hole, in the die hole of blanking die, be provided with the piercing punch coordinating with punching hole type hole, during punching production, upper bolster moves down under the effect of forcing press, punch-die has coordinated blanking processing with blanking die, piercing punch has coordinated punching processing with punching hole type hole, in a mold, just can complete blanking and the punching processing of workpiece, improved production efficiency, between blanking and punching two procedures, workpiece need not be taken out, avoided workpiece resetting, precision and the quality of workpiece have been improved, stripper and head part device can provide enough pressure for workpiece, avoid workpiece wrinkling, improved the surface quality of workpiece, very convenient and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As one embodiment of the present invention, as shown in Figure 1, a kind of flip-over type piercing and blanking die, comprise upper bolster 14, die shoe 1, die shank 11, guide pin bushing 15 and guide pillar 19, die shoe 1 upper surface is provided with punch-die 17, has punching hole type hole on punch-die 17, as preferably, punching hole type hole is up-small and down-big shoulder hole, facilitates the discharge of waste material.The outer stripper 5 that is socketed with of punch-die 17, stripper 5 is flexibly connected with die shoe 1 by unloading bolt 4, between stripper 5 and die shoe 1, be provided with rubber blanket 18, when rubber blanket 18 is during in uncompressed state, the upper surface of stripper 5 is thick higher than a punch-die 17 upper surface 2-3 workpiece material.
Upper bolster 14 lower surfaces are provided with blanking die 6, blanking die 6 lower surfaces have die hole, the position of die hole is corresponding with punch-die 17, in die hole, be provided with the piercing punch 13 coordinating with punching hole type hole, in the present embodiment, piercing punch 13 is up big and down small stairstepping, has improved the strength and stiffness of piercing punch 13.On piercing punch 13, be provided with head part device.In the present embodiment, as preferably, die hole is up big and down small shoulder hole, and piercing punch 13 is outer is socketed with ejector 16, and ejector 16 sidewalls are provided with boss, prevent that ejector 16 from coming off in die hole.Ejector 16 upper ends are connected with push rod 9, and push rod 9 upper ends are connected with push pedal 10, and push pedal 10 is movably connected in upper bolster 14, push pedal 10 upper ends with make bar 12 and be connected, make bar 12 and be movably connected in die shank 11, beat the upper end of bar 12 and stretch out die shank 11 and be socketed with nut.When undressed, the lower surface of ejector 16 is lower than the lower surface of blanking die 6.Crossbeam during work in press ram presses down makes bar 12, and push rod 9 promotes ejector 16 workpiece of blanking is released.
In the present embodiment, as preferably, punch-die 17 is connected with die shoe 1 by bottom plate 3, rubber blanket 18 is between stripper 5 and bottom plate 3, between punch-die 17 and die shoe 1, be provided with lower bolster 2, blanking die 6 is connected with upper bolster 14 by upper mounted plate 7, between blanking die 6 and upper bolster 14, is provided with upper padding plate 8.Upper padding plate 8 and lower bolster 2 can prevent upper bolster 14 and die shoe 1 wearing and tearing, have extended service life of the present invention.On die shoe 1 and lower bolster 2, have the through hole being communicated with punching hole type hole, facilitate the discharge of waste material.
