Abstract
An edging device or hemming device is disclosed with a machine frame (1), an edging bed (2) which is positioned inside said frame where it is raised and lowered with an edging lift and/or a displacement lift. A plurality of edging jaws are provided, which can be moved into the working area of the edging bed (2). Drive mechanisms are provided for the edging bed (2) and the edging jaws (3). The drive mechanisms for the edging lift and the displacement lift are configured as electromechanical drive mechanisms (7) which move the edging bed (2) using driven eccentric cams (12) or cranks. This simplifies the control of the drive mechanisms and reduces the masses of the structural parts being moved.
Claims20
A hemming device, comprising:
- a machine frame;
- a hemming bed arranged in said machine frame so as to be raised and lowered with a hemming stroke and/or a displacing stroke;
- a plurality of hemming jaws that can be moved into a working range of the hemming bed;
- a hemming bed drive connected to said hemming bed, said hemming bed drive including an electromechanical drive mechanisim for producing a hemming stroke and driven cams or driven cranks, said electromechanical drive mechanisim acting on said hemming bed via said driven cams or driven cranks;
- and
- a hemming jaw drive connected to said hemming jaws.
An edging device, comprising:
- a machine frame;
- an edging bed arranged in said machine frame so as to be raised and lowered with an edging stroke and a displacing stroke;
- a plurality of edging jaws that can be moved into a working range of the edging bed;
- an edging bed drive connected to said edging bed, said edging bed drive including an electromechanical drive mechanisim for producing an edging stroke and driven cams or driven cranks, said electromechanical drive mechanisim acting on said edging bed via said driven cams or driven cranks;
- and
- an edging jaw drive connected to said edging jaws for moving the edging jaws into and out of the working range of the edging bed.
An metal edge treatment device, comprising:
- a machine frame;
- a hemming bed arranged in said machine frame so as to be raised and lowered with a hemming stroke and a displacing stroke;
- a plurality of hemming jaws that can be moved into a working range of the hemming bed;
- pneumatic cylinders connected to said hemming jaws wherein said hemming jaws are mounted pivotably on said machine frame and can be pivoted with said pneumatic cylinders;
- a hemming bed drive connected to said hemming bed, said hemming bed drive including an electromechanical drive mechanisim for producing a hemming stroke and driven cams or driven cranks, said electromechanical drive mechanisim acting on said hemming bed via said driven cams or driven cranks;
- a hemming jaw drive connected to said hemming jaws for moving the hemming jaws into and out of the working range of the hemming bed, said hemming jaw drive being another electromechanical drive with driven cams or driven cranks, said another electromechanical drive being provided for the displacing stroke.
