Sheet metal processing is called sheet metal processing. In fact, for example, the use of plates to make chimney, iron barrel, oil tank, ventilation duct, elbow size head, round place, funnel shape, etc. The main processes are cutting, bending and buckling edges, bending and forming, welding, riveting, etc. Certain geometric knowledge is required. Sheet metal is thin plate hardware, that is, parts that can be processed by stamping, bending, Rashin and so on. A general concept is the parts that are thin and thick during processing. Correspondingly, there are castings, forgings, machined parts, and the like.

1. design

the design department designs the pictures of spare parts for sheet metal processing according to the requirements, and displays them one by one in the form of 3D, which is convenient for the processing department to process and fully shows the specific structure of sheet metal parts.

2. blanking

3. riveting

, the sheet metal can be riveted by punching or liquid pressure riveting machine.

4. welding

, when welding, a convex point should be made on the welding surface so that it can contact the surface of the flat plate during welding, and the welding time and pressure should be ensured during welding.

5. forming

Sheet metal forming: the main purpose is to bend and stretch the sheet metal. The bending processing sequence is mainly from inside to outside, from small to large, first folding special circumstances and then folding general shape priority processing.

6. finish

finish: according to customer's requirements, a protective film is plated on the surface of the sheet metal to increase the adhesion of the baking varnish. Through the automatic operation of the laser cutting machine, the sheet metal processing technology can be further improved, and the unmanned operation is realized, which not only saves the labor cost, but also greatly improves the production efficiency and increases the production quantity, which plays a significant role in the future development of sheet metal.
