In daily life, medical sheet metal processing is now widely used by us, and we also have a certain understanding, so you may not know what medical sheet metal processing is, then what are the processes of medical sheet metal processing?

1. After submitting the medical sheet metal processing drawing of the institute, select different feeding methods according to the expansion drawing and batch. Among them, there are laser, CNC punching machine, shearing machine, mold and so on. Then perform corresponding operations according to the medical sheet metal processing drawings. The influence of CNC stamping is affected by the tool. There will be large burrs on the edges of some special.
shaped workpieces and the edges of irregular holes. At the same time, the processing of burrs has a certain influence on the accuracy of the workpiece. Limited, flat section, suitable for processing special-shaped workpiece, but small workpiece processing time is longer. Placing the table next to the CNC and laser is conducive to machining on the machine to reduce the workload of the sheet. Put some usable walkways in designated places to provide material for the test model when bending.
2. The next process after the completion of the medical sheet metal processing, enter the lower process, and different workpieces enter the corresponding process according to the processing requirements. There are bending, riveting, cross strike, welding, convex hull, bad section. Sometimes after bending once or twice, the nut or nut must be depressed. Avoid first processing other processes, the required processing can not be completed. When there is a hook on the upper or lower cover, if the welding cannot be reached after bending, it is treated before bending.
3. Surface treatment Medical sheet metal processing workpiece should be bent, riveted and other processes, different plate surface treatment methods should be treated differently. Medical sheet metal processing Cold plate processing is generally surface plating. This is phosphate, spraying should be done after phosphating. Clean the surface of the plating plate, skip the oil, then spray. Stainless steel plate (with mirror plate, fog plate, wire drawing plate) can be brushed before bending, without spraying. If sprayed, oxidation is required. Different oxidation backgrounds are selected during processing.
4. Spray treatment After the medical sheet metal processing is completed, enter the spraying process. When the workpiece needs to be assembled, a part of the teeth or conductive holes must be protected.
5. Protective Treatment You can use a soft rubber stick or screw to check for perforations. If you need to conduct electricity, you should stick to high temperature tape positioning overalls for positioning and protection. The nut edge on the outer surface can be protected by screws to avoid the tooth loss caused by spraying into the nut (side) hole of the workpiece. When the workpiece is not equipped with spraying, the area that does not need spraying should be protected with screws or high temperature rubber plus high temperature tape and paper to block the outside.
6. After the pretend process is sprayed, the medical sheet metal processing enters the assembly process. Before assembly, tear off the original medical sheet metal processing and spraying, and copy the protective tape for medical sheet metal processing and spraying. Gloves, to avoid hands on the dust on the workpiece, some workpiece should be blown with an air gun.
7. Packaging process After the medical sheet metal processing is equipped, it will enter the packaging process. After the workpiece inspection, install the special packaging bag. Some workpieces without special packaging are wrapped in bubble wrap. Cut the bubble film to the size of the workpiece before packaging to prevent the processing speed from being affected after packaging; A large number of special cartons or bubble bags, rubber MATS, pallets, wooden boxes, etc. After packaging, put the carton, and then paste the corresponding finished product or semi-finished product label on the carton.
