The utility model discloses when carrying out product round hole punching press blanking, the waste material of punching press blanking can be crowded into the waste material between first inclined plane and the second inclined plane under the drift effect of punching press mechanism, and the waste material is blocked between first inclined plane and second inclined plane, can not appear jumping the bits condition.
Description
Technical Field
The utility model relates to a bits technical field is prevented jumping by punching press blanking round hole, especially relates to a bits structure is prevented jumping by punching press blanking round hole.
Background
At present, die-cut waste materials with very regular shapes such as round holes, rectangles and the like are arranged on a die of a metal piece of an electronic product, when the die is used for high-speed stamping production, the waste materials are required to be left in a knife edge of a lower die to be clamped or fall down after being cut, but when the shape of the die-cut waste materials is regular and simple, the waste chips left in a knife edge die core often jump upwards and fall onto a die surface, and the phenomenon is called chip jumping.
Scrap jumping can cause in-mold scrap and product overlapping extrusion to damage products and molds, and is not beneficial to control of product quality and production cost in mass production.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcoming that produces easily when punching press blanking on the mould that has the electronic product metalwork among the prior art and jump the bits, and the punching press blanking round hole that provides prevents jumping bits structure.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a bits structure is prevented jumping by punching press blanking round hole, includes the installation department, fixed mounting has punching press mechanism on the installation department, and is equipped with down the installation department under going up the installation department, the product has been placed above the installation department down, the product top is equipped with swager and constructs, installation department top surface is equipped with two edges of a knife, every down all be equipped with first inclined plane in the edge of a knife, every first inclined plane below all is equipped with the second inclined plane that is located on the edge of a knife inner wall, punching press mechanism drift bottom extrusion has the waste material.
Preferably, the inclination angle of the first inclined plane is 0.5 degrees, and the vertical height of the first inclined plane is 0.92 cm.
Preferably, the inclination angle of the second slope is 1 degree.
Preferably, the distance between the first inclined surface and the second inclined surface is 0.58 cm.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses when carrying out product round hole punching press blanking, the waste material of punching press blanking can be crowded into the waste material between first inclined plane and the second inclined plane under the drift effect of punching press mechanism, and the waste material is blocked between first inclined plane and second inclined plane, can not appear jumping the bits condition.
Drawings
Fig. 1 is a schematic structural view of a punching punched round hole scrap-jumping-preventing structure of the present invention;
FIG. 2 is an enlarged view taken at A in FIG. 1;
fig. 3 is the utility model relates to a top view of lower installation department in punching press blanking round hole anti-bouncing bits structure.
In the figure: the device comprises an upper mounting part 1, a stamping mechanism 2, a lower mounting part 3, a product 4, a pressing mechanism 5, a knife edge 6, a first inclined plane 7, a second inclined plane 8 and a waste material 9.
Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.
As shown in fig. 1-3, the punching blanking round hole scrap jumping prevention structure comprises an upper installation part 1, a punching mechanism 2 is fixedly installed on the upper installation part 1, a lower installation part 3 is arranged under the upper installation part 1, a product 4 is placed on the lower installation part 3, a material pressing mechanism 5 is arranged above the product 4, two knife edges 6 are arranged on the top surface of the lower installation part 3, a first inclined surface 7 is arranged in each knife edge 6, the inclination angle of the first inclined surface 7 is 0.5 degrees, the vertical height of the first inclined surface 7 is 0.92 cm, a second inclined surface 8 located on the inner wall of the knife edge 6 is arranged below each first inclined surface 7, the inclination angle of the second inclined surface 8 is 1 degree, the distance between the first inclined surface 7 and the second inclined surface 8 is 0.58 cm, and a waste material 9 is extruded at the bottom of a punch head of the punching mechanism 2.
The working principle is as follows: when punching and blanking round holes on a product 4, a punch of a punching mechanism 2 on an upper mounting part 1 punches and blanking round holes on the product 4, a punch of the punching mechanism 2 can extrude waste materials 9 into a knife edge 6 on a lower mounting part 3, when the waste materials 9 enter between a first inclined plane 7 and a second inclined plane 8, the waste materials 9 can be clamped by the first inclined plane 7, and the problem of scrap jumping cannot occur.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
