BENDING MACHINE FOR PRODUCING BENT PARTS FROM FLAT MATERIAL

The invention relates to a bending machine for producing bent parts from flat material (190), comprising an intake device for taking in flat material from a material reserve having flat material, a bending device having a bending head for bending the flat material into a two or three-dimensional, bent part made of flat material; and a cutting device for separating the bent part from the flat material which has been taken in. According to the invention, the bending head has a bending form (400) having a circumferential groove (420) for receiving a section of the flat material (190) to be bent and a bending tool, which can rotate about the bending form, for engaging on a section of the flat material to be bent. According to the invention, the bending form (400) is designed as a divided bending form, which has a bottom form part (430) and a top form part (440), which is movable relative to the bottom form part, wherein a bottom boundary surface (422-1) of the circumferential groove is formed on the bottom form part and a top boundary surface (422-2) of the circumferential groove is formed on the top form part, and the top form part and the bottom form part are movable relative to each other in order to modify the clearance height (H) of the circumferential groove between a closed configuration, having a relatively low clearance height, and an opened configuration, having a greater clearance height compared to the lower clearance height.
