Patent ID: 7021102

Claim:
A bending machine for the bending of rod-shaped and bar-shaped workpieces including: (a) support for the workpiece: (b) a tool platen ( 12 , 112 ); and (c) a bending device ( 5 , 105 ) comprising selectively deployable bending tools ( 10 , 11 ; 110 , 111 ) at least one of which is provided on one side of said platen and at least one other tool is provided on the opposite side of said tool platen ( 12 , 112 ), each bending tool including at least one bending swage ( 13 , 16 ; 113 , 164 ; 116 , 165 ) and at least one thrust member, said swage and thrust member being power driven in the transverse direction of the workpiece between an operating and idle position, said bending swages ( 13 , 16 ; 113 , 164 ; 116 , 165 ) being positioned along a bending axis ( 19 , 119 ) that extends in the transverse direction of the workpiece, the operating position of at least one thrust member on one side of the tool platen ( 12 , 112 ) being coordinated with the idle position of at least one thrust member on the other side of the tool platen ( 12 , 112 ), whereby, the workpiece on the active bending tool ( 10 , 11 ; 110 , 111 ), when effectively impacted in the transverse direction of the workpiece, can be bent around the bending swage ( 13 , 16 ; 113 , 164 ; 116 , 165 ) by means of at least one thrust member in its operating position, said at least one thrust member on one side and at least one thrust member on the other side of the tool platen ( 12 , 112 ) being coupled and jointly driven for their movement in the transverse direction of the workpiece, whereby, as the thrust member on one side of the tool platen ( 12 , 112 ) is moved in the transverse direction into its operating position, the associated thrust member on the other side of the tool platen ( 12 , 112 ) can be moved the opposite way in the transverse direction of the workpiece.
