Abstract
A rolling machine assembly for use in a press brake formed of an upper roll subassembly including an upper roll and an upper base and a lower roll subassembly including a pair of lower rolls and a lower base, the bases being detachably secured to the ram and bolster, respectively, of the press brake. Motors of the positive displacement type, fed from a flow divider, rotate the rolls to form a sheet of metal into desired curvature. The lower base has symmetrically located sockets for reception of the tines of a forklift truck so that when the upper roll is in nested position upon the lower rolls, and the securing means are disengaged, the subassemblies may be lifted out of the press brake as a unit by the forklift truck to free the press brake for other usage, and with the reverse procedure being effective for installation.
Claims10
A rolling machine assembly for rolling a sheet of metal into curved cross section and for use in a press brake having an elongated bolster and a ram coextensive therewith with powered means for reciprocating the ram and with adjustable stop means for positioning the ram at a predetermined elevation comprising, in combination, a lower roll subassembly including a pair of lower rolls and a lower base member with upstanding bearing blocks for supporting the lower rolls in slightly upraised position and laterally spaced from one another, an upper roll subassembly including an upper roll and an upper base member having bearing blocks thereon for supporting the upper roll in a depending position from the ram and centered between the lower rolls, means for detachably securing the lower base member to the bolster, means for detachably securing the upper base member to the ram, a lower hydraulic motor secured to the lower base member for driving the lower rolls, an upper hydraulic motor secured to the upper base member for driving the upper roll, the motors being of the positive displacement type, means for metering hydraulic fluid to the motors for rotation of the rolls at substantially the same peripheral speed, the lower base member having symmetrically located sockets for reception of the tines of a forklift truck so that when the upper roll is in nested position with respect to the lower rolls, and the securing means are disengaged, the subassemblies may be lifted out of the press brake as a unit by the forklift truck to free the press brake for other usage, and with the reverse procedure being effective for re-installation of the subassemblies in the press brake.
A rolling assembly for rolling a piece of metal into curved cross section and for use in a machine having a bed and a ram with means for raising and lowering the ram comprising, in combination, a lower roll subassembly including lower roll means and a lower base member with bearings for supporting the lower roll means above the base member, said lower base member being releasably mountable on the bed, an upper roll subassembly including an upper roll subasseblies may and an upper base member having bearings thereon for supporting the upper roll means in a depending position below the upper base member, means for detachably securing the upper base member to the ram, lower motor means secured to the lower base member for rotating the lower roll means, an upper motor secured to the upper base member for rotating the upper roll means, the lower subassembly having means for reception of the tines of a forklift truck so that when the upper roll means is resting on the lower roll means, and the securing means are disengaged, the subassembliesmay be lifted out of the machine as a unit by the forklift truck to free the machine for other usage, and with the reverse procedure being effective for re-installation of the subassemblies in the machine.
A rolling assembly for rolling a piece of metal into curved cross-section and for use in a machine having a bed and an overlying ram with means for raising and lowering said ram, said assembly comprising a lower roll subassembly including a lower base member and lower roll means, lower bearings on said lower base member for rotatably supporting said lower roll means above said base member, lower motor means supported on said lower base member for rotating said lower roll means, said lower base member being releasably mountable on said bed to enable said lower base member, said lower bearings, said lower roll means and said lower motor means to be removed as a unitary subassembly from said bed, an upper roll subassembly including an upper base member and upper roll means, upper bearings on said upper base member for rotatably supporting said upper roll means in a depending position below said upper base member, upper motor means supported on said upper base member for rotating said upper roll means, and means securing said upper base member to said ram and selectively releasable to permit said upper base member, said upper bearings, said upper roll means and said upper motor means to be detached as a unitary subassembly from said ram when said upper roll means is resting on said lower roll means whereby said upper subassembly may be removed from said machine as a unit with said lower subassembly.
