<p>A clamping device for a bending press is disclosed. The disclosed clamping device for a bending press is placed on both sides of a base corresponding to the lateral side of a lower mold and to control both ends of a pipe material to be bent in a bending press system, which includes the lower mold installed to be vertically movable through cushion pins on both sides of the base; and an upper mold installed to be able to vertically move on the upper part of the base. The clamping device for a bending press according to the present invention comprises i) a clamping die fixed on a base, having a space formed therein; ii) a clamping holder installed to be able to rotate by a rotary shaft inside the space of the clamping die; iii) upper and lower cam blocks installed to be able to horizontally slide on the upper and lower sides of the clamping holder respectively, having cam slopes, which are inclined toward the upper and lower sides, formed on mutually facing parts; iv) upper and lower clamping blocks installed to be able to slide in the facing direction on the upper and lower sides of the clamping holder by being in contact with the cam slopes of the cam blocks, clamping both ends of a pipe material; and v) a pressurization unit actually connected to the clamping holder, pressurizing the upper and lower cam blocks.</p> |
