How To Optimize Sheet Metal Profile Design
Metal pfofiles design included sheet metal cutting, blanking&bending or forming procedures.
Sheet metal parts have obvious advantages in strength, weight and cost. At the same time, compared with traditional parts, sheet metal parts have better point-to-point performance. Sheet metal parts have been gradually applied in high-tech fields such as electronic communication. People have gradually put forward higher requirements for the quality and function of sheet metal parts. The proper optimization of the original sheet metal processing technology has become the focus of sheet metal processing personnel.
First of all, sheet metal material blankingto the separation of sheet metal through the die. This link is usually applied to the processing of parts with relatively simple shape, so achieve a high degree of accuracy of processing shape and reduce the waste of materials to a great extent. Firstly, the shape of the blanking sheet metal parts should be controlled. In the corner area of the outer&inner holes of the blanking, the arc should be set to excessive the corner, which can avoid sharp angle and reduce the problem of mold cracking caused by improper subsequent heat treatment, which will affect the subsequent sheet metal construction.
Second, Metal sheet bending refers to the process of preventing the sheet metal material on the bending equipment, causing the elastic deformation of the sheet metal material through the pressure of the upper die or the lower die, and plastic deformation according to the actual design scheme after the elastic deformation. Different part sizes should be selected according to the actual design requirements. Local abnormal deformation is easy to occur in the bending link, which will affect the appearance quality and practical application of sheet metal parts. If you want to optimize the process for the bending link, the operator should make a pre cut according to the actual situation, so as to avoid the problem of subsequent deformation.
The press riveting link of sheet metal parts refers to the deformation of sheet metal materials through the action of pressure, so as to couple them together. This process is usually applied to screw press riveting, bolt press riveting and other links. As for the end press riveting operation link, the nut is usually circular and has an embossed gear and wire notch. Therefore, for the press riveting link of sheet metal parts, not only the quality of the original nut manufacturing link is optimized, but also the welding work is avoided.
Welding is one of the important ways to connect all parts of the structure together in the cold working link in the whole sheet metal processing process. Therefore, usually, this link will be operated under the background of high temperature. The common welding methods are argon arc welding and contact spot welding.
Therefore, in the actual welding link, different welding methods should be selected according to the properties of different sheet metal parts, so as to reduce the welding deformation to a great extent and improve the actual efficiency of welding. In the actual welding link, firstly, sufficient welding control shall be determined. Secondly, the length of the welding part shall be controlled more accurately to avoid sheet metal deformation and optimize the load of the welding point at the same time.
