Abstract

The utility model relates to a chip-jumping-resistance punching concave die applied to a base plate of a cavity of a microwave oven. The chip-jumping-resistance punching concave die comprises a concave die body, the longitudinal section of the concave die body is in a convex structure, the center of the concave die body is provided with a locating punching hole, a cutting edge part is arranged in the locating punching hole, and an inclined oblong slot is arranged in the inner side of the cutting edge part; through the gap adjustment of the oblong slot, extrusion movement on waste chips is formed, and the friction between the waste chips and the concave die is increased. Compared with the prior art, the chip-jumping-resistance punching concave die applied to the base plate of the cavity of the microwave oven has the advantages that the universality is great, the cost is saved, the generation of a chip jumping situation can be effectively prevented, and the like.

Description

Anti-scrap bouncing punching concave die for micro-wave oven cranial cavity base plate
Technical field
The utility model relates to a kind of punching concave die, especially relates to a kind of anti-scrap bouncing punching concave die for micro-wave oven cranial cavity base plate.
Background technology
In metal cool-press industry, the production efficiency of high-speed stamping die is high, and Product Precision is high, is convenient to realize automation and mechanization, suitable production demand, thereby be widely used in the stamped industry of the products such as automobile, electronics, household electrical appliance.
Punching concave die is used in automatic punching machine widely, development along with stamping technology, the single of punching press rushes speed and is also improving, new problem correspondingly also occurs thereupon, wherein with stampings because vacuum suction and clearance issues drop at die surface, cause waster and problem that mould is broken the most serious.
Utility model content
The purpose of this utility model is exactly to provide in order to overcome the defect of above-mentioned prior art existence the anti-scrap bouncing punching concave die for micro-wave oven cranial cavity base plate that a kind of versatility is good, cost-saving, can effectively prevent from jumping the generation of bits phenomenon.
The purpose of this utility model can be achieved through the following technical solutions:
An anti-scrap bouncing punching concave die for micro-wave oven cranial cavity base plate, is characterized in that, comprises die body, the longitudinal section of this die body is convex structure, its center is provided with position punch, is provided with cutting edge portion in this position punch, and this cutting edge portion inner side is provided with the elongated slot of inclination;
By the gap adjustment of elongated slot, form the compressional movement to scrap, strengthened the frictional force of scrap and die.
The width of described elongated slot and be highly 0.01~0.1mm.
Described elongated slot and the oblique angle of vertical direction are 3~7 °.
Described elongated slot and the oblique angle of vertical direction are 5 °.
Compared with prior art, the utlity model has following advantage:
1, versatility is good, for the punching of expecting the thick 0.6mm of being greater than, has certain versatility;
2, can effectively prevent from jumping the generation of considering phenomenon to be worth doing, by cutting edge portion inner side, be provided with the elongated slot of inclination, force the frictional force of scrap and die to strengthen, simultaneously because there are 5 ° of inclinations, make the suffered downward power of scrap much larger than the power of the rebound that makes progress.
3, cost-saving, the available former die transformation of the way.
Accompanying drawing explanation
Fig. 1 is existing cavity die structure schematic diagram;
Fig. 2 is existing die cutaway view;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is sectional structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
As shown in Figure 3-4, a kind of anti-scrap bouncing punching concave die for micro-wave oven cranial cavity base plate, comprises die body 1, the longitudinal section of this die body 1 is convex structure, its center is provided with position punch 2, in this position punch 2, is provided with cutting edge portion 3, and these cutting edge portion 3 inner sides are provided with the elongated slot 4 of inclination;
By the gap adjustment of elongated slot, form the compressional movement to scrap, strengthened the frictional force of scrap and die.The width of described elongated slot and be highly 0.1mm.The oblique angle a of described elongated slot and vertical direction is 5 °.Because there are 5 ° of inclinations, make the suffered downward power of scrap much larger than the power of upwards knock-oning.
