Claims (1)

[Claims for Utility Model Registration] 1. A pair of left and right support frames arranged parallel to each other in the same horizontal plane and attached to fixed base frames, and a plurality of rollers on each of these support frames, arranged in the same horizontal plane and A pair of left and right guide roller rows arranged in a row in the longitudinal direction of the support frame, arranged so that each axis is perpendicular to the longitudinal direction of the support frame, and rotatably attached to each other, and each of the guide roller rows. A pair of left and right guide plates respectively arranged along the direction in which the guide roller rows are arranged on the upper surface side, and a pair of left and right guide plates disposed on the upper surface side, respectively, and a pair of left and right guide plates disposed on the upper surface side, and a guide plate located in front of the rollers located at the front end of each guide roller row, and slightly from the upper surface of the guide roller rows. They are arranged at a high position slightly inside the inner guide surface of the guide plate, and protrude horizontally in the direction in which the guide rollers are connected, facing each row of guide rollers, so that the tip of the pipe to be perforated is inserted. A pair of left and right dies having an outer shape that can be removably inserted and having a female blade formed on the outer side of each circumferential surface, and a pair of dies arranged perpendicularly and horizontally to each of the dies, A structure comprising a pair of left and right punches supported to move forward and backward relative to the female blade of each die type, and a pair of left and right linear motion devices that move each punch forward and backward relative to the female blade of each die type. Frame pipe drilling device. 2 A pair of left and right holding frames are arranged on the fixed base frame in the same horizontal plane, and at least one of them is engaged with the fixed base frame so as to be movable back and forth in the horizontal plane while maintaining a parallel state with the other. A set of die molds, a punch, and a linear motion device are respectively attached to each of the holding frames, and at least one of the pair of left and right support frames is maintained in a parallel state with the other and is movable back and forth in a horizontal plane. Adjustment means is provided that is engaged with the fixed base frame and reciprocates at least one of the pair of holding frames and at least one of the pair of supporting frames to adjust the distance between both the holding frames and the distance between both the supporting frames. The drilling device for a building frame pipe according to claim 1.
