In the processing of metal stamping parts, what are the forms of the cutting edge?

In the processing of metal stamping parts, the form of the cutting edge can be divided into flat cutting, oblique cutting and roller cutting; The process of separating the sheet or coil of stamping parts. This flat-blade shearing method can only cut along a straight line. It is suitable for metal stamping sheet and coil materials with small shear width and large thickness; 2. Oblique blade shearing is different from flat blade shearing. Oblique blade shearing refers to the shearing process of sheet material or coil material on the shearing machine with the upper blade and the lower blade obliquely intersecting at a certain angle; The cutting edge and the material to be cut are not like flat-blade shearing, where all the cutting blades contact the sheet material and cut at the same time, but only a small part of the contact sheet material is gradually cut, so the oblique blade shear ratio Flat-blade shearing greatly saves the shearing force; shears, hand shears and desktop manual shears are all oblique blade shearing methods; third, the principle of roller shear; roller shear is referred to as rolling shear, also known as round shear Disc shearing is a shearing method in which the material is cut by passing between two disc hobs rotating in opposite directions; this method is usually used for metal stamping sheets or coils with extremely long cutting lines The longitudinal shearing of the material is an important means of material preparation. Generally, the two axes of the roller shear are parallel to each other and the plane of the shearing material is parallel to each other, but there are also deliberately made disc shear blades. , So as to be used for curve cutting work; Recommended article: In the production of stamping parts, several basic methods of shearing Previous post: What is the role of the edge in the processing of stamping parts?
