The way of punching metal stamping parts

In the processing of metal stamping parts, shearing is one of the more basic processes. A reasonable choice of metal stamping parts cutting equipment, according to the size of the production batch, the geometry and size of the cut metal stamping parts are different. There are many methods including: 1. Hand cut and Russell; 2. Shear on vibrating shear; 3. Shear on disc; 4. Shear on gantry shear. 5. Shearing on the uncoiling line; suitable for metal stamping parts with a thickness of less than 1 mm. The blanking or semi-finished products of stamping parts are hand-cut and such as shears. The cutting on the gantry shearing machine includes flat-blade shears and oblique blades. Two kinds of beds. The upper and lower edges of the flat blade bed are parallel, and the stamping parts are cut across the entire width at the same time when working. The flatness of the cut blank is relatively good, and its shearing force is relatively large, and it is generally used for the shearing of thin sheets; for shearing on the oblique-blade shearing machine, the upper and lower blades cross at a certain angle. Compared with the flat-blade shearing machine, the shearing force is small and the work is more stable. However, the pressure of the upper and lower shearing blades will cause the cut blank to bend downwards and squeeze out from the cut to produce distortion. , Especially when cutting thick and narrow strips, the distortion is particularly serious. Often times it must be leveled.
