Abstract
A bending machine has a main spindle which supports a die. There are two counter dies each mounted on a working arm which rotate about the main spindle. The working arms are driven by link arms which are acted on by a translational drive. There is versatile three-point bending caused by three die points, two on the working arms and one on the die support shaft. The working arm drive includes a translational component which extends through the die support shaft, and which is connected to the link arms. This achieves excellent symmetry and compactness.
Claims20
A bending machine comprising:
- a die support shaft having a die support shaft axis, said die support shaft having a through hole extending through said die support shaft axis,
- a die mounted on the die support shaft,
- at least two working arms:
- each supporting a counter die, and
- mounted to rotate about the die support shaft to move the counter dies to bend a work-piece in conjunction with said die on the die support shaft,
- link arms pivotally connected by pivot joints to the working arms, a translational drive:
- being coupled to said link arms,
- mounted to extend through said die support shaft through hole, and
- having a longitudinal axis along which said translational drive acts to drive the working arms via said link arms to rotate about the die support shaft.
