How to control the quality of sheet metal chassis processing?

　　I believe everyone knows that sheet metal chassis processing refers to the process of deforming a uniformly thin metal plate through stamping or manual processes, and some adjustment processes can be added to make it a more complex manufacturing workpiece. However, if we want to obtain good quality of sheet metal chassis processing, we need to control the standardized processing process to ensure the quality of the product.

　　Methods to control the quality of sheet metal chassis processing:

　　1. After the drawing is completed, when processing the sheet metal chassis, different punching methods should be selected according to different expansion diagrams and batches.

　　2. Sheet metal chassis processing welding includes argon arc welding, spot welding, carbon dioxide maintenance welding, manual arc welding, etc. Spot welding should first consider the welding direction of the workpiece and consider the manufacturing of the positioning object to ensure the accuracy of spot welding positioning in batch production.

　　3. When bending, the sheet metal chassis processing must identify the objects and slots used for bending according to the drawing scale and data thickness to avoid deformation caused by the collision between the product and the object. It is the key to select the upper die, and the selection of the lower die is identified according to the thickness of the plate.

　　4. In the process of sheet metal chassis processing, when stamping and riveting, the height of the studs should be fully considered to select different molds of the same type, and then the pressure of the press should be adjusted according to the actual situation.
