Sheet metal complete sets of products Manufacturer: How is sheet metal bending formed?

　　In the process of sheet metal bending, there are many things we need to pay attention to, such as: when using molds, when bending, when making processing drawings, etc. Sheet metal complete sets of products manufacturer: How is sheet metal bending formed?

　　Sheet metal complete sets of products manufacturer: How is sheet metal bending formed?

　　1. Processing principle: that is, sheet metal parts must meet processing requirements. Compliance with the processing technology principle is the most important of these four principles, directly affecting product quality, and is the first step in producing qualified products.

　　2. Easy flattening principle: When designing sheet metal parts, consider whether the bending and bevel are on the same horizontal plane, and there should be no interference between the two, otherwise it is an unqualified design. You also need to calculate the expansion size. According to the bending angle, there will be corresponding calculation formulas, related to parameters such as bending coefficient, plate thickness, fillet radius, and bending edge length.

　　3. Bending sequence principle of bending metal plates: Bending is about the sequence, mainly four points.

　　(1) Short side first, then long side.

　　(2) Outside first, then inside.

　　(3) Local first, then overall.

　　(4) Consider interference before determining the bending sequence.

　　4. Thickness principle: The plate thickness is generally in the range of 0.03-4.00 mm. The thicker the plate, the greater the processing difficulty, the greater the demand for large-scale equipment, and the lower the product qualification rate. Therefore, the appropriate thickness should be selected according to the actual function of the product. For most sheet metal parts, the thinner the better, controlled within 1mm. In addition to paying attention to the thickness, the sheet metal parts should also ensure uniform thickness during product design, especially in places with multiple bends, which can easily cause uneven thickness.

　　5. Sheet metal processing experience has summed up the four principles of sheet metal bending processing. Many novices often have scrapped bent parts during operation, and many bending problems can be solved as long as they follow the rules.

　　 Sheet metal complete sets of products Manufacturer: What about sheet metal and manufacturing processes?

　　Sheet metal complete sets of products manufacturer: With the development of science and technology, sheet metal involves a wide range of processing, such as computer cases and chassis.

　　1. There are many processes in the normal sheet metal processing process. If the processed sheet metal workpiece is complex, there will be more processes. After the workpiece is designed, the first step is blanking. There are many types of blanking. Different blanking methods should be selected according to the material, such as laser cutting, plate shearing, bending, punching, etc.

　　2. Commonly used materials for sheet metal processing include: cold-rolled sheet, hot-rolled sheet, galvanized sheet, copper sheet, aluminum sheet, stainless steel. After completing the first process, the burrs and corners left by cutting need to be polished, otherwise it will affect the surface accuracy and appearance of the workpiece. Then, according to the processing characteristics of different workpieces, enter the corresponding processes, such as spot welding, riveting, tapping, bending, flanging, etc. The welding of thin plates includes argon arc welding, carbon dioxide welding, etc. After welding, the corners need to be polished, and the surface treatment of the workpiece includes spraying and electroplating.
