A novel press brake is disclosed which incorporates a double lever actuating mechanism which is easily adjustable to vary the stroke of the press brake as well as adjusted to counteract the rotational forces imparted to the ram by reason of differential resistances created by the workpiece during the forming operation.
Claims7
A press brake comprising:
- (a) a frame;
- (b) a horizontally elongate die mount, said die mount fixed with respect to said frame;
- (c) a horizontally elongate ram mount mounted opposite said die mount for reciprocal movement with respect to said die mount;
- (d) a single actuating means for causing said reciprocal movement of said ram with respect to said die mount said actuating means affixed to a support member having a first end mounted on said frame and a free end slideably positioned adjacent said ram mount by a mounting collar;
- and
- (e) force amplification means attached to said actuating means for amplifying force applied by said actuating means and for transmitting said force to said ram mount at at least two spaced apart positions along the elongate axis of said ram.
