A core clamping device is provided to prevent the lateral side of a core from being damaged by a clamp pad and excessive pneumatic pressure by using a roller clamping a protruded piece of the core and restraining maximum pneumatic pressure of a pneumatic cylinder with a pressure regulator. A core clamping device clamps protruded pieces(11) projected on both sides of a core(10) by adjusting a gap between clamping arms(30) facing each other by a pneumatic cylinder(20) and vertically and horizontally moves in a transferring device. The core clamping device is composed of: clamp pads(100) fixed in the lower ends of the clamping arms, respectively; and a roller unit(200) disposed at the lower side of the clamp pad and provided with a roller rotatably supported to be protruded more inward than the clamp pad. |
