Metal processing sheet metal is a comprehensive cold processing process for metal sheets (usually below 6mm), including shearing, punching, bending, welding, riveting, mold forming and surface treatment. Its significant feature is the same thickness of the same part.

　 Sheet metal blanking methods mainly include number punching, laser cutting, shearing machine, mold blanking, etc. Numerical control is currently used. Laser cutting is mostly used in the proofing stage (stainless steel sheet metal parts can also be processed), and the processing cost is high. Die blanking is mostly used for large-scale processing. Introduce sheet metal blanking with number punching: number punching is also called turret numerical control punching machine, which can be used for blanking, punching, stretching holes, rolling bars, punching blinds, etc. Its processing accuracy can reach +/-0.1mm. Hardware processing numerical control The thickness of the machined plate is: cold-rolled plate and hot-rolled plate 4.0mm; aluminum plate 5.0mm; stainless steel plate 2.0mm. 1. There are smaller size requirements. The smaller size of punching is related to the shape of the hole, the mechanical properties of the material and the thickness of the material. 2. The hole spacing of the number of punches is related to the hole edge. When the punching edge of the part is not parallel with the edge of the part shape, the smaller distance should not be less than the material thickness t; when it is parallel, it should not be less than 1.5t. 3. When stretching holes, the smaller distance between the stretching hole and the edge is 3T, the smaller distance between the two stretching holes is 6T, and the smaller safe distance between the stretching hole and the bending edge (inside) is 3T + R (T is the thickness of the sheet metal, R is the bending fillet) 4. When punching the stretching and bending parts and the drawing parts, a certain distance should be maintained between the hole wall and the straight wall.
