Anhui stainless steel processing, Hefei stainless steel processing, Anhui sheet metal, Anhui sheet metal parts, Anhui sheet metal processing division and operation need to have clear regulations, according to the different plans and batches to choose different blanking methods, sheet metal processing methods Laser, CNC punching, shearing, mold and other methods, this article is mainly for the steps of Anhui sheet metal processing, mainly divided into the following points:
1. Select the blanking material. After the completion, enter the next process, and the different workpieces enter the corresponding process according to the processing requirements;
2. When bending, firstly determine the tool and sipe used for bending according to the size and material thickness on the drawing, to avoid the collision between the product and the tool, which is the key to the selection of the upper mold (in the same product, it may be The upper die of different models is used), and the selection of the lower die is determined according to the thickness of the plate;
3. When riveting, consider the same different molds for the height of the studs, and then adjust the pressure of the press to ensure that the studs and the surface of the workpiece are flush, to prevent the studs from being pressed or pressed out of the workpiece surface. Causes the workpiece to be scrapped. Welding has argon arc welding, spot welding, carbon dioxide protection welding, manual arc welding, etc. Spot welding must first consider the position of the workpiece welding. In the mass production of stainless steel sheet metal, consider positioning tooling to ensure accurate spot welding position.
4. In order to weld firmly, the bumps on the workpiece to be welded can make the bumps evenly contact with the flat plate before the electric welding, so as to ensure the uniform heating of the points, and also determine the welding position. Similarly, the welding is to be performed. It is necessary to adjust the preloading time, holding time, maintaining time and rest time to ensure that the workpiece can be spot welded firmly;
5. The sheet metal workpiece shall be surface treated after the completion of the bending, pressing and riveting process. The surface treatment of different sheet materials is different. After the cold plate processing, the surface plating is generally performed. After the plating, the spraying process is not carried out, and the phosphorus is used. After the phosphating treatment, it is sprayed. The surface of the plate is cleaned, degreased, and then sprayed;
6. After the surface of the Anhui sheet metal is treated in front of the surface, it enters the spraying process. When the workpiece is required to be assembled after spraying, the tooth or part of the conductive hole needs to be protected. The tooth hole can be inspected into a soft glue stick or screwed into the screw. It should be affixed with high-temperature tape, and the positioning tool should be positioned in large quantities to protect the inside of the workpiece. The nut (flange) hole visible on the outer surface of the workpiece can be protected by screws to avoid the workpiece after spraying. The back of the nut (flanged) hole is required;
7. After the spraying, enter the assembly process. Before assembly, the protective sticker used in the original spraying should be torn off to make sure that the threaded hole in the part is not sprinkled with paint or powder. In the whole process, wear gloves to avoid the hand. Dust is attached to the workpiece and some of the workpiece is blown clean. After assembly, the product enters the packaging process. After the workpiece is inspected, it is placed in a special packaging bag for protection. Some workpieces without special packaging are packaged with a bubble film. Before the packaging, the bubble film is cut into large pieces that can be packaged. In order to avoid one side of the package, it will affect the processing speed; stainless steel batches can be customized for special paper boxes or bubble bags, rubber pads, trays, wooden boxes, etc. After packaging, put it into the carton, and then put the corresponding finished or semi-finished label on the carton.
In addition to the strict requirements in the production process, the quality of Anhui sheet metal processing parts is the quality inspection that needs to be independent of production. First, the dimensions are strictly controlled according to the drawings, and the second is to strictly control the appearance quality. This can find unfolding errors in the process of sheet metal processing, bad habits in the process, and errors in the process.
