[0002] Sheet metal refers to metal components or parts made by sheet metal processing technology. Sheet metal can be used in various application fields, such as machinery, electronics, aviation, construction, etc. When bending sheet metal, it is generally done by using equipment such as bending machines, through the action of pressure and molds, to bend the sheet at the bending line to obtain the required bending shape;

[0003] With respect to the above-mentioned related technologies, the inventor believes that the sheet metal parts can be quickly bent by the pressure and the mold, but the general mold can relatively fix the bending angle of the sheet metal parts. When the sheet metal parts need to be bent at a larger angle, it may be necessary to replace the new mold or perform multiple bending processes on the sheet metal parts, which is relatively inconvenient and will affect the actual work efficiency accordingly.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By using the fixing parts and the braking parts and other related components in coordination, the two sets of threaded rods can be driven to rotate by using the braking parts such as the handle and the worm gear, so that the sheet metal parts of different widths can be clamped and fixed by using the fixing parts such as the fixing plate, so as to prevent the sheet metal parts from loosening and deviating when being bent, thereby affecting the bending stability and accuracy. Moreover, the provided fixing pad can prevent the sheet metal parts from being clamped and fixed, and can play an anti-slip role, and can also prevent the surface of the sheet metal parts from being worn, etc. At this time, the upper mold and the lower mold can be used to cooperate to bend the sheet metal parts, and the cylinder can be used to drive the T-plate to rotate, so as to perform a secondary bending process on the sheet metal parts and increase the bending angle.
