In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present utility model.
According to the utility model, the existing blanking equipment is researched and analyzed, the existing blanking equipment is used for flatly placing a plate on a female die with a concave structure, and then a male die is used for stamping a part of the plate suspended above the concave structure, so that the plate is sheared through the cutting edge of the male die, and further parts with required shapes and sizes are separated from the plate along a shearing contour line and fall into the concave structure. In order to ensure that the male die can completely penetrate through the plate, a gap of 3-5% is usually arranged between the outer contour of the male die and the contour of the opening of the concave structure based on the thickness of the plate so as to ensure that the male die and the concave structure are in clearance fit, so that the male die can realize full shearing of the plate and drive the sheared part to be completely separated from the plate and fall into the concave structure.
However, because of the gap between the male die and the concave structure, the section of the part separated from the plate is not formed entirely by the shearing action of the male die (the area formed entirely by the shearing action of the male die forms the bright band), and a part of the section is separated from the plate due to tearing and pulling actions, and the part of the section has a large collapse angle and tear band inclination, so that the part of defects need to be eliminated by secondary processing means such as grinding.
