A multi-directional multi-cam press device may include a cam base fixed to the lower mold, a first cam slide provided to slide forwards and backwards along a first direction of the cam base, at least a first punch unit provided in the first cam slide along a first direction, a cam drive fixed to an upper mold configured of moving in a vertical direction with respect to the lower mold, and making cam contact with the first cam slide, a second cam slide provided in the cam drive to move forwards and backwards in a second direction perpendicular to the first direction and in contact with the cam base side, and at least a second punch unit provided on the second cam slide along a second direction.

A modular roller hemming system having a base assembly, a replaceable anvil, a spider arm assembly, a plurality of support arms for supporting the spider arm assembly, and a plurality of repositionable unit tools. The anvil is 3-D printed of a polymer composite material and may be replaced with similarly manufactured anvils having different form factors for receiving various shaped and dimensioned workpiece assemblies. The plurality of support arms are repositionable on the base assembly, the spider arm assembly is reconfigurable, and the plurality of unit tools are moveable to accommodate various anvils having different form factors. The support arms includes an upper segment that is detachable from the lower segment to facilitate the changeover of anvils.

An expansion tool includes a housing and a collar rotatably coupled to the housing. The collar includes a plurality of slots. The expansion tool further includes a plurality of jaws, each jaw having a projection received in a corresponding one of the plurality of slots such that the jaws are coupled for co-rotation with the collar. The expansion tool also includes a mandrel movable relative to the housing between a retracted position and an extended position, the mandrel engageable with the jaws to expand the jaws in response to movement of the mandrel to the extended position, and a drive mechanism including a rotatable cam. Rotation of the cam moves the mandrel between the retracted position and the extended position. The expansion tool further includes a rotation mechanism configured to incrementally rotate the collar.

A tool for a press brake includes a tool main body, an attachment portion formed on a base end side of the tool main body and configured to be detachably attached to a tool installation portion of the press brake by using a tool changer, and a bending portion formed on a distal end side of the tool main body and used to bend a plate-shaped workpiece. An engagement hole having a circular cross-sectional shape to be engaged with a bar-shaped finger of the tool changer extends through the tool main body in a thickness direction. An anti-rotation bottomed depressed portion configured to receive a distal end of an anti-rotation member of the tool changer is formed in a vicinity of the engagement hole.

Various designs of die shoe assemblies are provided, each assembly configured to adjust vertical positioning of a die platform within the assembly, in order to correspondingly adjust vertical positioning of a die used with the assembly. The assemblies address limitations often associated with conventional die shoes designed to be used with shims. The assemblies use various methods and corresponding mechanisms to make the adjustment a time efficient process, while in so doing also enabling the desired extent of adjustment to be effectively and accurately provided.

The disclosure relates to a modular die for blanking a sheet for manufacturing individual blanks successively by a stroke of a ram of a press on tool parts for the blanks, the die having frame part (1,2), tool parts (3,4) placed in a gap between the frame part (1,2), where the tool parts (3,4) is maintained in position in the gap (5) by fixation parts (8,9,10,11). The fixation parts (8,9,10,11) engage with lateral surfaces (12,13,14,15) of the tool parts (3,4). Surfaces of the fixation parts (8,9,10,11) has a geometry congruent with a geometry of lateral surfaces (12,13,14,15) of the tool part (3,4). The disclosure also relates to tool parts of the modular die, to a method for operating the modular die and to a use of the modular die for manufacturing, as example, brake shims.
