There are many operations that choose this processing method because processing can improve the function and service life of the product. Of course, we all know that the processing technology is indeed a bit troublesome, but the processing of the sheet metal chassis can bring benefits to the enterprise, so there will be many operation options. Due to processing reasons, sheet metal processing technology and equipment are also very important, which is related to the quality of the product. In sheet metal processing, the accuracy will be very low. How to control the quality of sheet metal parts? Today, I will explain to you:

1. According to different extended drawings and batches, after the drawings arrive, choose different stamping methods.

2. Stamping different workpieces according to processing requirements.

3. when bending, the bending of tools and grooves must be admitted according to the ratio and thickness data of the drawing, so as to avoid deformation caused by collision between large sheet metal processing products and tools, which is the key to selecting the upper die, the selection of the lower die is based on the thickness of the plate.

4. The general rule of sheet metal chassis processing and bending is first inside and then outside, first small and then large, first special and then general.

5. When punching and riveting, before adjusting the press pressure, the same or different mold should be selected according to the height of the stud.

6. Welding includes argon arc welding, spot welding, carbon dioxide maintenance welding, manual arc welding, etc. In order to ensure the accuracy of spot welding positioning in mass production, spot welding should first consider the welding direction of the workpiece and consider production positioning.

7. After the installation is completed, enter the packaging process, check the workpiece, and put it into a special packaging bag for maintenance.

8. Enter the equipment process after spraying. In the whole process of sheet metal precision processing, wear gloves to prevent the hands attached to the workpiece from being covered with dust. Some workpieces must be blown clean with an air gun.

9. The surface treatment of the sheet metal chassis processing shell is different for different steel plates. Generally, the surface is plated after the cold plate treatment, and no spray treatment is performed after the plating. Electroplating plate cleaning, degreasing, spraying.
