The products processed by sheet metal technology are called sheet metal parts. During the processing of sheet metal parts, burrs will be generated on their edges, and then a trimming device is needed to reprocess the sheet metal parts.

A fixed frame is fixedly installed on the top surface of the operating table, and a hydraulic push cylinder is fixedly installed on the top surface of the fixed frame. Both sides of the middle end of the piston rod of the hydraulic push cylinder are hinged with push rods through first rotating shafts. Through the meshing of the transmission gear, the transmission rack and the movable rack, while the hydraulic push cylinder operates to drive the cutter to move vertically for edge cutting treatment, the transmission rack can be driven to move horizontally, and then the movable rack is driven to move horizontally inside the fixed frame, and then the limiting plate is driven to move towards each other to perform side support treatment on the sheet metal part.

[0004] In the above technical solution, although it can be realized that during the cutting of the sheet metal part, it is fixed synchronously and aligned, but during the fixing process, due to the different sizes of the sheet metal parts, it is difficult to maintain when the cutter moves downward, and it is difficult to fix sheet metal parts of various different sizes, resulting in the offset of the sheet metal part during the cutting process and poor trimming effect.
