When metal stamping parts are processed, what are the forms of the cutting edge

Precision, focusing on the customized production of precision stamping parts for more than ten years, we have accumulated rich experience here, welcome to inquire with pictures. There are many processes in the processing and production of metal stamping parts, such as punching, rotary cutting, tapping, blanking, etc. In this article, we will learn about the forms of the cutting edge when metal stamping parts are processed? In the processing of metal stamping parts, the form of the cutting edge can be divided into flat blade shear, oblique blade shear and roller shear. 1. Flat-blade shearing refers to the process of separating the sheet or coil of metal stamping parts with two blades parallel to each other. This flat-blade shearing method can only cut along a straight line. It is suitable for Metal stamping sheets and coils with small shearing width and large thickness; 2. Oblique blade shearing is different from flat blade shearing. Oblique blade shearing refers to the oblique intersection of the upper blade and the lower blade of the sheet or coil. The process of shearing on a shearing machine at a certain angle; when cutting with an oblique blade, the shearing blade and the material to be sheared are not like flat blade shearing, where the shearing blades all contact the material for simultaneous shearing, but Only a small part of the contact sheet material is gradually cut, so the oblique blade shearing greatly saves the shearing force than the flat blade shearing; shears, hand shears and desktop manual shears are all oblique blade shearing methods; three , The principle of roller shear; roller shear is abbreviated as roller shear, also known as disc shear, which is a shearing method in which materials pass between two disc hobs rotating in opposite directions to be cut; This method is usually used for longitudinal shearing of metal stamping sheets or coils with extremely long cutting lines. It is an important means of material preparation. Usually, the two axes of roller shear are parallel to each other and are used for shearing. The planes of the cutting material are parallel to each other, but there are also deliberately made disc shear blades to be used for curved cutting.
