ABSTRACT:
A small-diameter metallic conduit bending machine includes a stationary frame. The stationary frame made of bar stock or pipe stock is shaped so as to substantially conform to a finished metallic conduit. The stationary frame includes a bending section which has in its lengthwise direction a curvature smaller than the bend radius of the metallic conduit and in its widthwise direction a guide surface substantially orthogonal to the bend plane of the metallic conduit. A bending member whose outer peripheral surface faces the guide surface is disposed movably toward the stationary frame so that the metallic conduit can be bent so as to lie along the guide surface. The bending member is moved by an actuator when the actuator is in its pulling stroke.
