Sheet metal parts processing procedures

Sheet metal parts processing procedures

1. Designed sheet metal parts drawing, constructed the structure of sheet metal parts in detail, and drew the expansion drawing, that is, the part expansion drawing with complex structure;

2, blanking, blanking methods are many, usually by several combinations.

A. Use the shear machine to cut out the expansion drawing, that is, the shape, length and width of the required sheet metal parts, and combine the punching machine and mold to punch holes and cut angles;

B. Short working hours and high efficiency are required for blanking of the punch. The structure of the flat parts after the parts are expanded is processed into shape by using the punch in different steps.

C. CNC blanking, through the preparation of numerical control program, numerical control machine tool according to the program to punch into shape. There is also laser blanking, which USES laser cutting.

3, flanging tapping flanging is hole extraction, that is, the smaller base hole into a larger hole, increase the strength, prevent sliding teeth, usually used for thin sheet metal processing.

4, punch processing punch processing by the corresponding mold to complete the operation, such as: punching Angle, punching blanking, punching convex bag and other processing methods.

5, pressure riveting processing through the punch or pressure riveting machine to complete the operation, such as pressure riveting stud, pressure riveting nut, pressure riveting screw.

6, bending processing is usually completed by the processing of the folding bed and bending die coordination, the plane material into three-dimensional shape.

7, welding processing welding is the combination of multiple parts together, usually have robot welding, carbon dioxide welding, argon arc welding, spot welding and other ways. Choose according to the requirements.

8, surface treatment is usually used to protect the material, prevent oxidation, coating the surface of the material with protective film, such as: phosphide film, paint, etc.

Assembly refers to the combination of multiple parts in a specific way to make them into finished products.
