The requirements for the appearance of the sheet metal chassis and cabinet are increasing day by day. There are many sheet metal processing processes, and the complexity is also increasing simultaneously. The product is accelerating at a new speed. How to complete the details of the chassis and cabinet? How to do a good job in processing each process? Next, Jinan cabinet manufacturer will analyze for you:
1. Die stamping
For the processing of the complex structure of the chassis and cabinet, the conservative processing methods and processes cannot be realized. This requires the manufacture of hardware molds. The cabinet with simple shape and small size can be formed by blanking and forming die stamping at one time; The box with complex shape and large volume can be divided into several parts for stamping and forming, and then realized by tailor-welding or bolt connection, assembly and other methods.
2. Comprehensive connection method
It is mainly used in the processing of sheet metal workpiece with variable cross-section, especially for some curved surfaces. Generally, the variable cross-section sheet metal processing mainly selects the curved surface parts that need to be divided into different features, and then classifies and processes the curved surface parts with different features, such as the units that need to be processed by stamping dies, the units that need to be processed by simple processing tooling, the units that need to be bent simply, the units that need to be processed by curve blanking and cold, and then splices these units into a whole.
3. Simple forming bending method
The flat sheet will form bending overflow through proper cutting, and the bending surface of various angles will be formed through stamping with concave and convex cutters. Each bending surface will be enclosed in different boxes, and the joints will be connected by full welding, spot welding, fillet welding or edge welding.
4. Piecewise welding and wire repair method
For cases and cabinets with large volume and complex shape, it is a good way to save the processing cost by using the method of block processing, then welding and wire repair.
