[0026] In this embodiment, when buffering is required during the bending process, by opening the hydraulic cylinder 1, the hydraulic cylinder 1 will drive the pressure rod 4 to press down. During the pressing process, the pressure rod 4 will drive the lower pressure column 203 to press down. When the lower pressure column 203 is pressed down, it will drive the upper mold 204 to press down. When the upper mold 204 is pressed down, it will drive the bending knife fixed at the bottom to press down to bend the sheet metal on the lower mold 207. When pressing down, the upper mold 204 drives the bending knife to contact the sheet metal on the lower mold 207. When the sheet metal on the lower mold 207, the telescopic column 205 will telescope upward.
