Abstract
The utility model discloses a novel progressive die, and relates to a punching die. The novel progressive die comprises an upper die seat, a lower die seat and a die handle. The upper surface of the lower die seat is provided with a concave die, and the lower surface of the upper die seat is provided with a blanking protruding die. A blanking concave die hole is formed in a position, corresponding to the blanking protruding die, on the concave die, and a discharging plate is connected on the blanking protruding die in a sleeved mode. The discharging plate is movably connected with the upper die seat through discharging screws, and the discharging screws are connected with a discharging rubber pad in a sleeved mode. a lower backing plate is arranged in a position, close to the blanking protruding die, on the lower surface of the upper die seat, and the lower surface of the lower backing plate is provided with a hole punching protruding die. A hole punching concave die hole is formed in a position, corresponding to the hole punching protruding die, on the concave die. The novel progressive die can sequentially finish hole punching and blanking of workpieces in a set of die, improves production efficiency, avoids repeated positioning of the workpieces, improves production accuracy, is not prone to breaking down in the hole punching protruding die, long in service life, and simple and manufacture process, and reduces die cost.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of novel progressive die.
Background technology
Punching press is at room temperature to utilize the mould that is installed on the forcing press that material is exerted pressure, and 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 manufacturing.Usually need to punching on the workpiece of blanking in punch process, use existing mould to need first in blanking die then the workpiece blanking is put into the perforating die punching, operation is many like this, production efficiency is low, and workpiece needs resetting, has affected precision and the quality of product.Generally be the less aperture in aperture in the hole of blank upper punch in addition; when carrying out the aperture moulding; its corresponding punch is elongate rod; strength and stiffness are poor, and punch is easy to produce flexural deformation and fractures when stamping-out, when being rushed material when thicker; the easier fracture of punch; to often shut down the replacing punch, reduce operating efficiency, increase die cost.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of novel progressive die, can successively finish punching and the blanking of workpiece in a mold, has improved production efficiency, has avoided the workpiece resetting, has improved Product Precision.And piercing punch of the present utility model is frangibility not, long service life, and mold production process is simple, has reduced die cost.
The technical solution of the utility model is: a kind of novel progressive die, comprise upper bolster, die shoe and die shank, the die shoe upper surface is provided with die, the upper bolster lower surface is provided with blanking punch, the position corresponding with blanking punch has the blanking die hole on the die, be socketed with stripper on the blanking punch, stripper is flexibly connected by unloading bolt and upper bolster, be socketed with the discharging rubber blanket on the unloading bolt, the upper bolster lower surface is provided with lower bolster near the position of blanking punch, the lower bolster lower surface is provided with piercing punch, the position corresponding with piercing punch has the punching concave die hole on the die, piercing punch is socketed in the stripper, and relatively on the stripper, lower movement.
As preferably, blanking punch is fixedly connected with upper bolster by upper mounted plate, is provided with upper padding plate between blanking punch and the upper bolster, and lower bolster is fixedly connected on the upper mounted plate lower surface, and piercing punch is fixedly connected with lower bolster by bottom plate.
As preferably, the stripper upper surface has the groove that cooperates with bottom plate, and described piercing punch is three, and parallel interval is arranged at the lower bolster lower surface, and the aperture in blanking die hole increases from top to bottom gradually, and the punching concave die hole is up-small and down-big shoulder hole.
The beneficial effects of the utility model are: be respectively arranged with blanking punch and piercing punch on the utility model upper bolster, be respectively arranged with blanking die hole and punching concave die hole on the die, during punching production, strip is finished punching first under the effect in piercing punch and punching concave die hole, then strip is moved to the position of blanking punch, blanking punch and blanking die hole cooperate finishes blanking, movement along with strip, the strip of back can be finished punching and blanking processing continuously, easy to process, production efficiency is high, workpiece need not be taken out between blanking and the punching two procedures, avoid the workpiece resetting, improved precision and the quality of workpiece.Piercing punch of the present utility model is arranged on the lower bolster, and fix by bottom plate, such structure has shortened the length of piercing punch greatly, avoided piercing punch in the stamping-out process, to produce flexural deformation and fractureed, the strength and stiffness of piercing punch have greatly been improved, prolong the service life of piercing punch, need not often change piercing punch, improved operating efficiency.And mold production process is simple, and die cost is low, and is very convenient and practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of novel progressive die comprises upper bolster 7, die shoe and die shank, and the die shoe upper surface is provided with die 1, upper bolster 7 lower surfaces are provided with blanking punch 8, position corresponding with blanking punch 8 on the die 1 has the blanking die hole, in the present embodiment, and as preferably, the aperture in blanking die hole increases from top to bottom gradually, makes things convenient for the discharge of blank.Be socketed with stripper 2 on the blanking punch 8, stripper 2 is flexibly connected by unloading bolt 3 and upper bolster 7, be socketed with discharging rubber blanket 4 on the unloading bolt 3, upper bolster 7 lower surfaces are provided with lower bolster 10 near the position of blanking punch 8, lower bolster 10 lower surfaces are provided with piercing punch 9, and position corresponding with piercing punch 9 on the die 1 has the punching concave die hole, as preferably, the punching concave die hole is up-small and down-big shoulder hole, makes things convenient for the discharge of waste material.Piercing punch 9 is socketed in the stripper 2, and stripper 2 moves up and down relatively.
In the present embodiment, as preferably, blanking punch 8 is fixedly connected with upper bolster 7 by upper mounted plate 5, is provided with upper padding plate 6 between blanking punch 8 and the upper bolster 7, lower bolster 10 is fixedly connected on upper mounted plate 5 lower surfaces, and piercing punch 9 is fixedly connected with lower bolster 10 by bottom plate 11.
