A method for bending and forming sheet metal parts

Abstract

The invention belongs to the technical field of sheet metal processing, in particular to a bending forming method for sheet metal parts. The bending forming method adopts a multi-roller floating bending machine. The multi-roller floating bending machine comprises a machine body, a downward pressing module, a main pressure head, auxiliary pressure heads, an adjusting unit, movable dies and a fixeddie, wherein a controller is arranged on the machine body. The controller is located at one side of the machine body. The downward pressing module is located at the upper part of the machine body andis used to press down the main pressure head and the auxiliary pressure heads. The main pressure head is fixedly connected with the downward pressing module. The auxiliary pressure heads are of the same structure as the main pressure head, and the auxiliary pressure heads and the main pressure head are used for bending the sheet metal parts. The adjusting unit is positioned between the auxiliary pressure heads and the downward pressing module and is used for adjusting the auxiliary pressure heads to ascend or move left and right. The movable dies are located at one side of the lower part of the machine body and is in sliding connection with the machine body. The movable dies are used for bending the sheet metal parts. According to the bending forming method, the forming size of the sheet metal parts can be ensured by fine-adjusting the shapes of the sheet metal parts, and the forming qualification rate of the sheet metal parts is increased.

[0002] Sheet metal processing is a comprehensive cold processing process for metal plates, including shearing, punching / cutting / compositing, folding, welding, riveting, splicing, forming, etc. Its notable feature is that the thickness of the same part is the same; sheet metal parts are thin plate hardware Parts, that is, parts that can be processed by stamping, bending, stretching, etc.; sheet metal has the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. Electronic appliances, communications, automobile industry, medical equipment and other fields have been widely used. As the application of sheet metal becomes more and more extensive, the demand for sheet metal parts is increasing, and the shapes of sheet metal parts are also changing. The corresponding equipment and methods for the production of sheet metal parts need to keep pace with the times, and the efficiency of sheet metal parts production needs to be improved; at the same time, the dimensional accuracy requirements for sheet metal parts are also further improved, especially for some key auto parts. The size requirements of the sheet metal parts are relatively high, and there are some curved parts, and the size of the produced parts is difficult to guarantee. Therefore, how to improve the method of sheet metal forming, improve the quality of sheet metal forming and production efficiency is a problem worthy of continued research.
