Summary of the invention

Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of flip-over type piercing and blanking die is provided, can in a mold, have completed blanking and the punching of workpiece, improved production efficiency, avoid the workpiece resetting, improved Product Precision.

The technical scheme that the utility model adopts is: a kind of flip-over type piercing and blanking die, comprise upper bolster, die shoe, die shank, guide pin bushing and guide pillar, the upper bolster upper surface is arranged at intervals with some annular protrusions, the die shoe upper surface is provided with punch-die, on punch-die, have the punching hole type hole, punch-die is socketed with stripper outward, stripper is flexibly connected by unloading bolt and die shoe, between stripper and die shoe, be provided with rubber blanket, the upper bolster lower surface is provided with blanking die, the 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 coordinated with the punching hole type hole, on piercing punch, be provided with the head part device.

As preferably, die hole is up big and down small shoulder hole, piercing punch is socketed with ejector outward, the ejector sidewall is provided with boss, and the ejector upper end is connected with push rod, and the push rod upper end is connected with push pedal, push pedal is movably connected in upper bolster, the 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, is provided with upper padding plate between blanking die and upper bolster.

The beneficial effects of the utility model are: on punch-die of the present utility model, have the punching hole type hole, in the die hole of blanking die, be provided with the piercing punch coordinated with the 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 the 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 the workpiece resetting, precision and the quality of workpiece have been improved.The upper bolster upper surface is arranged at intervals with some annular protrusions, has improved the intensity of upper bolster, has extended service life of the present utility model.Stripper and head part device can provide enough pressure for workpiece, avoid workpiece wrinkling, have improved the surface quality of workpiece, very convenient and practical.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: 1, die shoe; 2, lower bolster; 3, bottom plate; 4, unloading bolt; 5, stripper; 6, blanking die; 7, upper mounted plate; 8, upper padding plate; 9, push rod; 10, push pedal; 11, die shank; 12, make bar; 13, piercing punch; 14, upper bolster; 15, guide pin bushing; 16, ejector; 17, punch-die; 18, rubber blanket; 19, guide pillar.

The specific embodiment

Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.

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, upper bolster 14 upper surfaces are arranged at intervals with some annular protrusions, have improved the intensity of upper bolster 14, extended service life of the present utility model, die shoe 1 upper surface is provided with punch-die 17, on punch-die 17, has the punching hole type hole, as preferably, the 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 by unloading bolt 4 and die shoe 1, between stripper 5 and die shoe 1, be provided with rubber blanket 18, when rubber blanket 18 was in uncompressed state, the upper surface of stripper 5 was thick higher than punch-die 17 a upper surface 2-3 workpiece material.
