Abstract

DC60 (14/01/48) The invention herein is a preparation of pipe bending apparatus having the functions of tension bending and compression bending which can perform the various bending operations in a single unit. The apparatus performs the bending by rotating the pipe at a predetermined angle to the pipe pressed against the surface along the circumference of the bending mold, whereby the apparatus shall consist of a movable pipe bending unit which can move in the longitudinal direction of the pipe to be processed or a stationary pipe bending unit and a pipe twisting unit which can rotate the pipe freely at a predetermined angle to the center of the pipe which is the center of the axis specified that the pipe bending unit performs either tension bending or compression bending or both and is provided in a manner that it can rotate in a vertical plane about an axis parallel to the center of the axis of the pipe so as to reduce the distance of movement and position in which the pipe twisting operation is performed. The invention herein is a preparation of pipe bending apparatus having the functions of tension bending and compression bending which can perform the various bending operations in a single unit. The apparatus performs the bending by rotating the pipe at a predetermined angle to the pipe pressed against the surface along the circumference of the bending mold. The bending machine shall consist of a movable pipe bending unit capable of moving in the longitudinal direction of the pipe to be processed or a stationary pipe bending unit and a pipe closing unit for free rotation of the pipe to a predetermined angle with the center of the pipe, which is the center of the axis, and shall be characterized as performing either tension bending or compression bending, or both, and shall be arranged in such a way that it can rotate in a vertical plane about an axis parallel to the center of the axis of the pipe so as to minimize the range of movement required to perform the pipe bending operation.
