Abstract
The invention provides a sticking point type waste material anti-jump die which comprises a concave die and a punch head, wherein the concave die is internally provided with a die cavity, and an opening wall of the upper opening of the die cavity is a knife edge. The sticking point type waste material anti-jump die is characterized in that the die cavity is internally provided with a lug boss. According to the sticking point type waste material anti-jump die, the die cavity of the concave die is internally provided with the lug boss, and the sticking point type contact is formed between the lug boss and waste material, so that the frictional resistance between the waste material and the die cavity can be increased, and when the punch head is withdrawn out of the concave die, the waste material can be stuck by the lug boss, and can not be taken by the punch head. A product can not be pressed to be damaged, so that the normal production can be guaranteed, and the production efficiency can be improved.
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.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of card point mode 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, the mouth wall suitable for reading of die cavity is the edge of a knife, is provided with projection in the described die cavity.
In order to prevent that drift is scratched, described convex surfaces is arcwall face.
In order to increase the frictional resistance between projection and the waste material, prevent that better waste material from jumping material, described projection is strip, the length direction of projection and the depth direction of die cavity in the same way, the protruding bottom that extends to die cavity from the edge of a knife of die cavity.
In order further to increase the frictional resistance between projection and the waste material, better prevent waste material jumping material, the protrusion height of described projection is uprised to the end away from the edge of a knife gradually by an end of the contiguous edge of a knife.
Beneficial effect of the present invention: the present invention arranges projection in the die cavity of die, forms the card point mode contact between projection and the waste material, has increased the frictional resistance of waste material and die cavity, and drift is when withdrawing from die, and projection can be blocked waste material, does not allow it be brought up by drift.Guarantee that product can not weighed wounded, thereby guarantee normal production, enhance productivity.
Description of drawings
Fig. 1 is the structural representation of die of the present invention;
Fig. 2 is A-A profile among Fig. 1;
Fig. 3 is that the present invention shears schematic diagram;
Fig. 4 is the right TV structure schematic diagram of Fig. 3;
Among the figure: 1, die, 1-1, the edge of a knife, 1-2, die cavity, 1-3, projection, 2, flitch, 2-1, waste material.
The specific embodiment
A kind of specific embodiment as depicted in figs. 1 and 2, it comprises die 1 and drift, and drift does not draw in the drawings, adopts the ordinary construction drift to get final product, and is provided with die cavity 1-2 in the die 1, and the mouth wall suitable for reading of die cavity 1-2 is edge of a knife 1-1, is provided with protruding 1-3 in the die cavity 1-2.
Projection 1-3 surface is preferably designed as arcwall face, and the outer contour in the cross section of protruding 1-3 is camber line, can prevent that like this drift is scratched.
The projection 1-3 can be arranged to strip, the depth direction of the length direction of protruding 1-3 and die cavity 1-2 in the same way, protruding 1-3 extends to the bottom of die cavity 1-2 from the edge of a knife 1-1 of die cavity 1-2.
Projection 1-3 can also be designed to have certain taper, and the protrusion height of protruding 1-3 is uprised to the end away from edge of a knife 1-1 gradually by the end of contiguous edge of a knife 1-1.
During punching work: as shown in Figure 3 and Figure 4, with flitch 2 clampings on die 1, guarantee that protruding 1-3 has the 0.13cm height overlapping with plate, then use drift punching flitch 2, drift is pressed into the die cavity 1-2 of die 1 with the waste material 2-1 under the punching, and when drift withdrawed from, waste material 2-1 was stuck on the protruding 1-3, drift can not taken waste material out of, thereby has avoided waste material to jump out die 1.
Claims (4)
1. the anti-jump mould of card point mode waste material comprises die and drift, is provided with die cavity in the die, and the mouth wall suitable for reading of die cavity is the edge of a knife, it is characterized in that: be provided with projection in the described die cavity.
2. the anti-jump mould of card point mode waste material according to claim 1, it is characterized in that: described convex surfaces is arcwall face.
3. the anti-jump mould of card point mode waste material according to claim 1 and 2, it is characterized in that: described projection is strip, the length direction of projection and the depth direction of die cavity in the same way, the protruding bottom that extends to die cavity from the edge of a knife of die cavity.
4. the anti-jump mould of card point mode waste material according to claim 3 is characterized in that: the protrusion height of described projection is uprised to the end away from the edge of a knife gradually by an end of the contiguous edge of a knife.
