Abstract
Disclosed is a machine for bending rod-shaped material in two directions, comprising a rotable plate (5), fitted with a centrally positioned mandrel (12) and an eccentrically positioned bending tool (13), and a fixed, adjustable holder (15; 17). The plate is mounted coaxial to a housing (1) which is in turn mounted to rotate in a fixed support about an axis (X--X) (4). The plate can be turned by means of a rotary drive (18) mounted on the housing. The holder is positioned eccentrically on the housing and can be brought by means of the rotary drive (18) up against the material to be bent.
Claims18
A bending machine for bending bar-shaped material in two directions, having
- a stationary frame (4);
- a single bending disc (5) rotatable about a fixed central axis (x--x);
- a central bending mandrel (12) on the disc (5);
- an eccentrically located bending tool (13, 29) on the disc;
- a housing (1) rotatably supported for rotation in two opposite directions about the axis (x--x) on the stationary frame (4);
- an adjustable steadying element (15, 17, 26) secured to the housing, for holding the material to be bent against the disk (5);
- wherein the bending disc (5) is located coaxially with the housing;
- the bending mandrel is coaxial with respect to said axis (x--x);
- a rotary drive mechanism (18) is provided, mounted on the housing (1) and drivingly coupled to the bending disc (5);
- and
- wherein the steadying element (15, 17, 26) is eccentrically located on the housing, rotation of the housing by said rotary drive mechanism resulting in engagement of the material to be bent against said steadying element.
