Abstract
The invention discloses a die used for punching a tiny hole in a thick material, and relates to a punching die. The die used for punching the tiny hole in the thick material comprises an upper die base, a lower die base and a die shank, wherein a concave die is arranged on the upper surface of the lower die base, a concave die hole is formed in the concave die, a pressure plate is arranged below the upper die base and movably connected with the upper die base through a pressure screw, the pressure screw is sleeved with a pressure rubber pad, a through hole is formed in the pressure plate, a small pressing plate is arranged in the through hole, and the small pressing plate is in clearance fit with the through hole and is movably connected with the upper die base through a screw; a return spring is arranged between the small pressing plate and the upper die base; a convex die is arranged at the position, corresponding to the concave die hole, of the small pressing plate; a pressing block is arranged at the position, corresponding to the convex die, of the lower surface of the upper die base. According to the die used for punching the tiny hole in the thick material, the convex die does not break up easily and is long in service life, manufacturing processes of the die are simple, production efficiency is improved, and cost of the die is lowered.
Description
Technical field
The present invention relates to a kind of diel, relate in particular to a kind of thick material and rush orifice 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.While using existing diel to carry out aperture moulding; its corresponding punch is elongate rod; strength and stiffness are poor; when stamping-out, punch is easy to produce flexural deformation and fractures; when being rushed material when thicker, punch more easily ruptures, and often shut down replacing punch; reduce operating efficiency, increased die cost.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of thick material and rushes orifice die, and its punch is frangibility not, long service life, and mold production process is simple, has improved production efficiency, has reduced die cost.
Technical scheme of the present invention is: a kind of thick material rushes orifice die, comprise upper bolster, die shoe and die shank, die shoe upper surface is provided with die, on die, have die hole, upper bolster below is provided with holding pad, holding pad is flexibly connected with upper bolster by binder screw, on binder screw, be socketed with binder rubber blanket, on holding pad, have through hole, in through hole, be provided with little pressing plate, little pressing plate coordinates with via clearance, and be flexibly connected with upper bolster by screw, between little pressing plate and upper bolster, be provided with back-moving spring, position corresponding with die hole on little pressing plate is provided with punch, the position that upper bolster lower surface is corresponding with punch is provided with briquetting.
As preferably, briquetting is fixedly connected with upper bolster by fixed head, between briquetting and upper bolster, is provided with backing plate, and upper bolster lower surface is provided with guide pin bushing, and die shoe upper surface is provided with the guide pillar coordinating with guide pin bushing.
As preferably, also comprise little guide pillar, on die, have pilot hole, little guide pillar upper end is fixedly connected in fixed head, and lower end is passed little pressing plate and is stretched in pilot hole, little guide pillar and pilot hole matched in clearance, it is outside that back-moving spring is socketed on little guide pillar.
The invention has the beneficial effects as follows: punch of the present invention is arranged on little pressing plate, during punching press, upper bolster moves down under the effect of press ram, briquetting clashes into little pressing plate and completes punching, such structure has shortened the length of punch greatly, avoided punch to produce flexural deformation in stamping-out process and fractureed, extend the service life of punch, need not often change punch, improved operating efficiency.And mold production process is simple, die cost is low.Little guide pillar has guaranteed the kinematic accuracy of punch, has improved the quality of product, 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 thick material rushes orifice die, comprise upper bolster 8, die shoe 18 and die shank 9, die shoe 18 upper surfaces are provided with die 1, have die hole 19 on die 1, in the present embodiment, as preferably, the aperture of described die hole 19 increases from top to bottom gradually, facilitates the discharge of waste material.On die shoe 18, have the through hole being communicated with die hole 19.Upper bolster 8 belows are provided with holding pad 3, holding pad 3 is flexibly connected with upper bolster 8 by binder screw 5, on binder screw 5, be socketed with binder rubber blanket 6, on holding pad 3, have through hole, in through hole, be provided with little pressing plate 16, little pressing plate 16 coordinates with via clearance, and be flexibly connected with upper bolster 8 by screw 10, between little pressing plate 16 and upper bolster 8, be provided with back-moving spring 15, position corresponding with die hole 19 on little pressing plate 16 is provided with punch 4, and the position that upper bolster 8 lower surfaces are corresponding with punch 4 is provided with briquetting 11.
In the present embodiment, as preferably, briquetting 11 is fixedly connected with upper bolster 8 by fixed head 7, between briquetting 11 and upper bolster 8, is provided with backing plate 12, and upper bolster 8 lower surfaces are provided with guide pin bushing 14, and die shoe 18 upper surfaces are provided with the guide pillar 17 coordinating with guide pin bushing 14.
In the present embodiment, as preferably, also comprise little guide pillar 13, on die 1, have pilot hole, little guide pillar 13 upper ends are fixedly connected in fixed head 7, and lower end is passed little pressing plate 16 and stretched in pilot hole, little guide pillar 13 and pilot hole matched in clearance, back-moving spring 15 is socketed on little guide pillar 13 outsides.During punching press, between punch 4 and die hole 19, rely on little guide pillar 13 guiding, improved the kinematic accuracy of punch 4.
In the present embodiment, as preferably, die 1 upper surface is provided with guide plate 2, and position corresponding with die hole 19 and little guide pillar 13 on guide plate 2 has through hole.Guide plate 2 can be punch 4 location when punching press, has further improved the kinematic accuracy of punch 4.As preferably, punch 4 is two, and parallel interval is arranged on little pressing plate 16, and corresponding die hole 19 is also two, facilitates the moulding of a plurality of apertures on workpiece.
