A method of bending and forming a sheet metal part after stamping

Abstract

The invention relates to a bending forming method of a sheet metal part after stamping, which mainly includes the following steps, including clamping and fixing, hole groove processing, bending processing, detection operation, quantitative collection and other processes, and the sheet metal parts used after stamping The bending and forming equipment includes a bottom plate, a clamping and rotating device, an intermittent rotating device and a clamping device. The present invention can solve the following problems in the bending and forming of existing sheet metal parts. a. At present, the sheet metal parts are processed into angled It is necessary to bend sheet metal parts. In mass production, bending machines are often used, but the bending machine is not easy to adjust the bending angle of sheet metal parts. It often needs to be stopped. Bending operations waste a lot of time, reduce production efficiency, and waste the time for manual machine adjustment; b. When the bending machine bends sheet metal parts, the bending effect is not stable due to the unstable bending process. Poor, the product defective rate is high.

Problems solved by technology

[0002] Sheet metal is a comprehensive cold working process for thin metal plates (usually below 6mm), including shearing, punching / cutting / compositing, folding, welding, riveting, splicing, forming (such as automobile body), etc. Its distinctive feature is the same The thickness of the parts is the same, and the products processed by the sheet metal industry are called sheet metal parts. The sheet metal parts referred to by different industries are generally different, and they are mostly used for assembly. The sheet metal parts are the products of the sheet metal process. With the maturity of mechanical processing technology and the rapid development of various processing equipment, bending operations are required during the processing of sheet metal parts. After the lower mold is selected, the corresponding bending angle of the workpiece is limited to a fixed value, which cannot be adjusted according to the needs. Adjustment, which limits the range of production and processing to a certain extent, reduces the flexibility of production, and the applicability and practicability are limited. Therefore, a device suitable for multi-angle bending is needed to solve this problem, thereby reducing time and economic cost

[0003] However, the following problems exist in the bending and forming of existing sheet metal parts, a. At present, sheet metal parts are processed into angled parts, and sheet metal parts need to be bent. In mass production, bending machines are often used, but The bending machine is not easy to adjust the bending angle of sheet metal parts, and often needs to be shut down. After complex angle adjustments, the bending operation is performed, which wastes a lot of time, reduces production efficiency, and wastes manual machine adjustment. time; b, when the bending machine bends the sheet metal parts, due to the unstable bending process, the bending effect is poor, and the phenomenon of bending springback also occurs from time to time, and the product defective rate is high, which can improve the quality of the product Yield and Productivity in Sheet Metal Bending
