Choose the common sense that you need to know before you can do the processing of Dongguan sheet metal.
Dongguan sheet metal processing, in the processing industry, sheet metal processing has become a more prominent form of processing, sheet metal products are increasingly popular with users, such as lockers, work benches, shelves, sheet metal cabinets, etc. They have been changed from the previous plastic to sheet metal, which increases the strength of the use and prolongs the service life. Sheet metal processing can be divided into ordinary processing and precision processing. For ordinary sheet metal finished products, the difference is the precision of the required items, such as some ordinary daily occupation items, ordinary processing standards can meet the process requirements. Precision sheet metal is important for industries with special assembly requirements or high shape requirements. Here are some common knowledge about sheet metal from Guangzhou Baosen:
After the drawings are handed, select different blanking methods according to the different drawing and batch, including laser, CNC punching, shearing, mold and other methods, and then make corresponding opening according to the drawings. Place the workbench next to the CNC and the laser to facilitate the placement of the sheet on the machine for processing, reducing the workload of the lift. Some of the available edge material is placed in a designated place to provide material for the test mode when bending. After the workpiece is blanked, the corners, burrs, and joints must be trimmed (grinding). At the tool joint, the flat boring tool is used for dressing. For the larger burr workpiece, the grinding machine is used for dressing, and the small bore joint is at the joint. It is trimmed with the corresponding small trowel to ensure the appearance of the appearance. At the same time, the trimming of the shape is also ensured for the positioning during bending, so that the position of the workpiece on the bending machine is consistent when bending, and the size of the same batch of products is guaranteed.
After the blanking is completed, the next process is entered, and different workpieces enter the corresponding process according to the processing requirements. There are bending, riveting, flanging, spot welding, convex hull, step difference, sometimes the nut or stud should be pressed after bending one or two times, where the mold is convex and the difference is considered. First processing, so as to avoid interference in other processes after processing, can not complete the required processing. When there is a hook on the upper cover or the lower case, if it cannot be welded after bending, it should be processed before bending.
After the workpiece is bent, the riveting and other processes are completed, the surface treatment is carried out. The surface treatment methods of different plate materials are different. After the cold plate processing, the surface plating is generally performed. After the plating, the spraying process is not performed, and the phosphating treatment is adopted. Spray treatment after the treatment. The plated surface is cleaned, degreased, and then sprayed. Stainless steel "target=_blank> stainless steel plate (with mirror panel, fog panel, drawing plate) can be drawn before bending, no need to spray, if it needs to be sprayed to be roughed; aluminum plate is generally treated with oxidation, according to spraying Different colors to choose different oxidation background
Commonly used are black and natural oxidation; aluminum plates need to be sprayed for chromate oxidation treatment. Surface pretreatment can make the surface clean and significantly improve the adhesion of the film, which can double the corrosion resistance of the film. The cleaning process first cleans the workpiece, first hangs the workpiece on the assembly line, first through the cleaning solution (alloy de-oil powder), then into the clean water, then through the spray zone, then through the drying zone, and finally the workpiece from the assembly line Take it down.
This is the general process of ordinary sheet metal processing. The work is very simple, but sometimes it is difficult to do it. To make a horizontal and quality sheet metal product, it is not necessary to talk about it. The real operation of the sheet metal platform is understandable.
