Abstract
The invention discloses a special-shaped punch type waste material jumping prevention mold, which comprises a female mold and a punch, wherein a die cavity is arranged in the female mold, the punch comprises a punch main body, at least one side of the punch main body is provided with a lug boss, included angles between two side surfaces of the lug boss and the plane of the punch main body, on which the lug boss is arranged, are respectively acute angles, and the shape of the mold cavity of the female mold is matched with the shape of the punch main body. One lug boss is arranged on waste materials punched by the mold, the lug boss of the waste materials is buckled with a corresponding groove in the mold cavity, the friction force is greater, and the waste materials cannot be taken out by the punch. The special-shaped punch type waste material jumping prevention mold is particularly suitable for punching and shearing samples with a special-shaped region to be punched and shorn and lower precision requirements on the product size.
Description
Technical field
The present invention relates to a kind of mould, particularly a kind of punching mould.
Background technology
In general diel, often can run into when shearing profile, only shear on one side; because punch press runs up; often can be coming on the scrap belt, thus perhaps having oil to be bonded at above the waste material to take the edge of a knife above the drift out of weighs product wounded, and severe patient can break mould.
Particularly punching as shown in Figure 1 treat punching district 2 for abnormity treat punching sample 1 time, and since drift and die be difficult to process and treat punching district 2 corresponding polymorphic structures, therefore prior art becomes can cover the cuboid for the treatment of punching district 2 with the Cross section Design of punch body in design, must cause like this waste material of punching to have a plurality of limits not contact with the film chamber of die, frictional force between waste material and the die is little, waste material easily occurs jump out.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of abnormal-shaped punch formula waste material anti-jump mould, be such that it will prevent the waste material under the punching to jump out die.
In order to solve the problems of the technologies described above, the present invention includes die and drift, be provided with die cavity in the die, described drift comprises punch body, at least one side of punch body is provided with boss, the angle on the plane on the two sides of boss and the boss place punch body is acute angle, and the die cavity of die is corresponding with the punch body shape.
For the contact area of the die cavity that increases waste material and die, the angle of the two sides of described boss is 30 degree.
For the ease of processing, the end face of described boss is the plane.
For the ease of processing, be equipped with the rounding structure between the plane on the side of the side of described boss and end face and boss and the boss place punch body.
In order to prevent from damaging product, described punch body is provided with the limiting stand that the restriction punch body enters die depth.
Beneficial effect of the present invention: a boss is arranged on the waste material that mould of the present invention sweeps away, and the corresponding groove of the boss of waste material in die cavity fastens, and frictional force is larger, and waste material is difficult for being taken out of by drift.Be particularly suitable for punching and treat that the punching district is special-shaped and the sample not high to the product size required precision.
Description of drawings
Fig. 1 treats punching sample structure schematic diagram;
Fig. 2 is that drift is in the perspective view for the treatment of on the punching sample;
Fig. 3 is the structural representation enlarged drawing of drift;
Among the figure: 1, treat the punching sample, 2, treat the punching district, 3, drift, 3-1, limit convex, 3-2, punch body, 3-3, boss.
The specific embodiment
A kind of specific embodiment as shown in Figure 3, it comprises die and drift 3, be provided with die cavity in the die, drift comprises punch body 3-2, the side of punch body 3-2 is provided with boss 3-3, the angle on the plane on the two sides of boss 3-3 and the boss 3-3 place punch body 3-2 is acute angle, so that boss 3-3 is dovetail shaped.The die cavity of die is corresponding with punch body 3-2 shape, that is: so that die has the groove of a dovetail groove shape.
The angle of the two sides of boss 3-3 is preferably 30 degree, and the waste material of going out like this can form two wedge angles, and two wedge angles are stuck in the die cavity, and waste material is difficult for jumping out.
The end face of boss 3-3 is preferably the plane, is convenient to like this process drift 3.
On drift 3, preferably also adopt following structure: be equipped with the rounding structure between the plane on the side of the side of boss 3-3 and end face and boss 3-3 and the boss 3-3 place punch body 3-2.Punch body 3-2 is provided with the limiting stand 3-1 that restriction punch body 3-2 enters die depth.
Operation principle: followingly be illustrated as example take the punching punching sample 1 for the treatment of shown in Figure 1.
The punching sample 1 for the treatment of shown in Figure 1 is placed on the die, as shown in Figure 2, drift 3 downward punching presses, on the waste material that sweeps away than treating that punching district 2 has more the boss of a dovetail type, the corresponding groove of the boss of waste material in die cavity fastens, and frictional force is larger, and waste material is difficult for being taken out of by drift.
Claims (5)
