Embodiment Construction

[0029] figure 1 An oblique perspective view of a bending machine 1 for bending a rod-shaped or tubular workpiece 2 drawn continuously from a coil is shown.

[0030] The bending machine 1 comprises a frame 3 provided on its upper side with a straightening unit 4 and a rotatable feeder 5 .

[0031]The workpiece 2 extracted from the coil in a continuous manner is first drawn from the rear side of the bending machine 1 ( figure 1 Middle: from the right) is supplied to the straightening unit 4, through which the workpiece 2 enters the rotatable feeder 5, exits from the rotatable feeder 5 at the front, and is then supplied to the bending head at the front of the bending machine 1 6. The bending head 6 has a rotatable bending disc 7 for performing the desired bending.

[0032] The curved disk 7 assumes a curved form, which is rotatable in both directions of rotation about an axis of rotation 8 which is arranged in a vertical direction and perpendicular to the longitudinal axis of t...

Abstract

A support jaw arrangement for sliding lateral support of rod-shaped and tubular workpieces prior to their entrance into a forming groove of a bending head of a bending machine. The support jaw arrangement includes two support jaws, one on each side of the workpiece. Each support jaw is fastened on a holder to a support bracket which, guided in a longitudinally displaceable manner on a guide block, is displaceable by a drive device from an initial position retracted against the direction of transport of the workpiece parallel to the same, to an end position extended in the direction of transport of the workpiece. One support jaw supports the workpiece in a laterally sliding manner in a region from its tangential entrance into the forming groove, up to a point at a predetermined distance infront of the same while the other support jaw assumes a retracted initial position. A bending machine comprising the support jaw arrangement is also provided.

Description

technical field [0001] The invention relates to a support jaw arrangement for slidingly laterally supporting a rod-shaped tubular workpiece before it enters a forming groove of a bending head in a bending machine. Background technique [0002] In a bending machine for bending rod-shaped or tubular workpieces by means of a bending head, there is the possibility that, during the bending process, in a certain area before the workpiece enters the forming groove of the bending form, the continuously fed workpiece to be processed Subject to an undesirably high degree of warping (kinks, bulges, etc.) The form of the segment is bent, and the workpiece is arranged in this shaped groove. [0003] In order to prevent this from happening, in known bending machines, the support jaws are placed in said region against the side of the workpiece to be processed which faces away from the bending head and the bending disc. [0004] DE 201 18 444 U1 shows such a device provided with supportin...
