Sheet metal processing is the processing and production of sheet metal to make it a sheet metal part with a certain structure. Its processes generally include cutting and punching, bending, folding, crimping and deep drawing, welding, bonding and so on.
There are four basic procedures in sheet metal processing: shearing, punching/cutting, folding, and welding.
1. Laser: Laser cutting is the main equipment for blanking. It has fast processing speed, high precision, short cycle (no need to open molds), and can process various shapes. It is the main processing method for sheet metal blanking.
2. Punching: The sheet metal parts can't only have a flat shape. You need to punch a convex hull, shoot a sprout, punch blinds (a kind of vent), bridges, buckles, etc. All need to be processed. Punching is not the previous punching machine, but a numerical control punching machine. It can install dozens of molds, is programmable, has high speed, and can also assist the laser cutting machine in blanking.
3. Folding: It is to use CNC bending machine, bending center (manipulator-assisted bending), CNC bending machine, etc. to perform the main bending of the plate.
4. Welding: argon arc welding of thin plate welding, carbon dioxide gas shielded welding, welding robot, etc.
note:
1. The material is lacking and the boss is too high, which exceeds the ductility of the material. The boss is generally used to increase the installation size or avoid installation conflicts. Therefore, the boss must not change the internal structure of the material or affect the structural strength. Make.
2. Redundant materials: redundant materials are common where multiple bend edges are closed, and most of them are process errors or drawing errors
3. Bending restrictions: most bending machines have certain restrictions on bending
Single-side height: the size of the Bender and the height of the upper knife, the solution can be multilateral large-angle bending
Bilateral height: sheet metal processing is not greater than the maximum height of a single side. In addition to all the restrictions of the unilateral height, it is also restricted by the bottom side: bending height
