Precision sheet metal processing
Product Details：
The precision sheet metal processing process has the following points: the feeding-rivet/bend-point welding-assembly-packaging and other processes.
1. Moisture: According to different drawings, the method of feeding is also different. There are mainly CNC punching, laser cutting, etc. Let's expand the feeding process one by one.
1) After the processing of CNC punch, the edge of the workpiece may have a large burr.
2) Laser processing section is flat, which is very suitable for processing of alien workpieces.
Pay attention to the necessary polishing of the corners and burrs after the feeding, which is convenient for bending to ensure that the size of the same batch of products is consistent.
2. After the feeding is completed, enter the next process. Different sheet metal pieces have different sheet metal processing processes. The crafts include bending, riveting, point welding, etc. These processes.
1) Press rivet: According to the height and size of the thread. For molds, when using a pressure machine, ensure that the surface of the nut and sheet metal parts must be flat.
2) Bending: According to the size of the bending material required on the drawing, select the corresponding thickness tool and a cowhide groove.
3) Point welding: In order to be welded firmly, the connection of the workpiece and the workpiece should be made of convex welding, while the welding position should be guaranteed.
According to the processing process, there are the following precautions:
1. The bumps and regions with poor steps to be poured out must be processed first, so as not to interfere with each other after processing. The next step cannot be processed.
2. Bey bend must first determine the order of bending. The general law is from the inside to the outside, from small to large, from special to ordinary. 3. Welding marks on the surface of the sheet metal parts after point welding, and the welding marks are used for grinding beds.
3. After the workpiece, the workpiece must enter the assembly and packaging process after the bending, riveting and other processes.
According to assembly and packaging procedures, please note:
1. Please wear gloves before assembly to avoid the dust on the hand attached to the workpiece. Some workpieces need to be blown with air guns.
2. After the workpiece passes the inspection, put it in a special packaging bag to protect the workpiece. For large quantities, special cartons or air bubble bags, rubber pads, trays, wooden boxes, etc. can be customized to protect sheet metal parts.
In addition to the strict requirements for the production process of sheet metal parts, precision sheet metal processing needs to be inspected for quality inspection. The first is to control the size of the sheet metal parts strictly in accordance with the drawings, and the second is to strictly control the appearance quality of the sheet metal parts. The appearance of the sheet metal does not allow any scratches (flowers). Waste processing. In this way, you can compare whether the drawing is wrong, whether there are bad operating habits in the production process, and whether there are errors in the production process.
