Abstract:
1. A bending press system, comprising: at least one guide post; a slide plate mounted at a slider so as to be slidable upwardly or downwardly along the guide post; a bending die including a lower die having an upper surface and an upper die having a lower surface corresponding to the upper surface of the lower die and mounted on a lower surface of the slide plate, and adapted to bend an object supplied between the lower die and the upper die to have a predetermined curvature; and a pair of clamping means mounted respectively at both sides of the bending die corresponding to the bending die and adapted to clamp both end portions of the object, wherein the clamping means comprise: a clamping block provided with a space formed therein and a slot formed at a surface thereof along a length direction of the bending die; an insert cylinder mounted at an outer surface of the clamping block in the length direction of the bending die and having an operating rod; a clamping jaw disposed in the space of the clamping block, connected to the operating rod of the insert cylinder, and having an inner end portion at which a receiving recess for receiving an end portion of the object is formed and an outer end portion connected to the slot through a slot pin; a clamping cylinder mounted corresponding to the receiving recess at an upper end of the clamping jaw through a bracket and having an operating rod; and a clamper disposed in the receiving recess and connected to the operating rod of the clamping cylinder so as to be movable in a vertical direction.
