What is the process of sheet metal processing? The process of sheet metal processing includes the following steps: blanking-riveting/bending-spot welding-assembly-packaging and other processes.

1. Blanking: According to different drawings, there are different blanking methods, such as CNC punching machine and laser cutting. 1) Large burrs may appear on the edge of the workpiece processed by the CNC punch. 2) The laser processing section is flat, which is very suitable for the processing of special-shaped workpieces. After blanking, it should be noted that the corners and burrs should be polished to facilitate positioning during bending and ensure the same batch of products with consistent size.

2. After blanking, enter the next process. Different sheet metal parts have different processing procedures. The processes include bending, riveting, spot welding, etc. These processes. 1) Riveting: Select the mold according to the height and size of the stud, and make sure that the stud and the sheet metal surface are flush when using the press. 2) Bending: According to the size of the required bending material on the drawing, select the corresponding thickness of the bending knife and the bending groove. 3) Spot welding: In order to weld firmly, the connection between the workpieces must be bump welded, and the welding position must be accurate.

According to the processing procedure, we should pay attention to the following points: 1) Use the mold to punch the convex hull and the parts with poor spacing to process first to avoid interference after other processes, and the next processing cannot be completed. 2) Bending must first determine the order of bending. The general rule is from inside to outside, from small to large, from special to ordinary. 3) After spot welding, there will be welding scars on the surface of sheet metal parts, which should be treated with a grinder.

3. After the bending, riveting and other processes are completed, the workpieces should be assembled and packaged. According to the assembly and packaging processes, attention should be paid to: 1) Before assembly, wear gloves to prevent dust on the hands from attaching to the workpieces. Some workpieces also need to be used Air gun blow clean. 2) After the workpiece passes the inspection, it is put into a special packaging bag to protect the workpiece. For large batches, special cartons or bubble bags, rubber pads, pallets, wooden boxes, etc. can be customized to protect the sheet metal parts.

In the process of sheet metal processing, in addition to strict production requirements, each sheet metal part needs to be inspected for quality. First, the size of sheet metal parts must be strictly controlled in accordance with the drawings; second, the appearance of sheet metal parts must be strictly controlled. The appearance of sheet metal parts is not allowed to have scratches (flowers), and sheet metal parts with inconsistent sizes are reworked or scrapped. In this way, you can compare whether there are errors in the drawings, whether there are bad operating habits during the manufacturing process, and whether there may be errors during the manufacturing process.

Sheet metal processing involves a lot of processing procedures, there are a lot of safety issues need to pay attention to, what are the safety measures in the production of sheet metal processing.

1. In the process of operation, the spirit should be concentrated. 2. Wear the prescribed labor protection articles. 3. In strict accordance with the operating procedures, do a good job of personal equipment. 4. During the operation, it is strictly forbidden to put your hands between the upper and lower molds. Before taking protective measures, try to avoid duplication. When processing small pieces, use tweezers or other special tools for operation. 5. When bending, before taking out the parts in the mold, it is not allowed to put in the second part. When blanking and punching, the parts falling on the edge of the mold should be cleaned in time, otherwise it is not allowed to continue punching. 6. After cutting off the power supply, it is strictly forbidden to use the punch with the slider falling freely and bursting during work. 7. If the mold is not fastened and the gap is not adjusted properly, do not start the machine tool.
