Description

Technical Field

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car body), etc. Its notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts.

[0003] After searching, the publication number is: CN220144568U, which discloses a sheet metal bending and forming machine for mechanical processing. By setting a second fixing component, it plays the role of squeezing and fixing the left and right side surfaces of the sheet metal. Under the cooperation of each other, the sheet metal is fixed up and down, left and right, which solves the problem that the sheet metal is easy to tilt left and right when subjected to force during the bending process, thereby improving the bending effect. However, the above-mentioned prior art can only bend the sheet metal once at a time. When the sheet metal needs to be bent into a U shape, it is necessary to bend one side of the sheet metal and then adjust the position of the sheet metal for a second bending, which is time-consuming and labor-intensive.
