    摘要： A butt welding and burr shearing machine for metal rod, e.g., reinforce steel has opposed relatively slidable clamping devices (8, 9), which has positioning clamp (10) and pivotable clamp lever to clamp the rod by lever action. One of the clamping devices mounts split type shear dies by the positioning clamp and the clamp lever respectively. In the cutting position of the shear dies 21, 22 the rod F2 is not clamped by the clamping device 10 on which the shear dies are mounted.By a series of simple operations the rods to be jointed are loaded sideways, clamped by rotating clamp lever, and pressure butt welded, and bulge formed by welding process is sheared off. The completed rod is removed sideways.

    摘要： A punching-shearing method for inspecting the quality of a butt welded joint comprises pressure butt welding steel members under heat to form an annular bulge around the joint portion of the steel members, punching-shearing the bulge under red heat immediately after the pressure butt welding process from one side of the bulge in parallel with the axes of the steel members by use of a shearing die having higher and lower shearing edge portions so that the higher shearing edge portions penetrate the bulge prior to the lower shearing edge portions, so as to cause the base of the bulge to remain around the joint portion in a slightly higher position than the peripheral surfaces of the steel members, and determining the quality of the joint portion from the peripheral surface of the base of the bulge remaining on the joint portion.

    摘要： A small-sized gas pressure welding machine for rails comprises a pressure application unit and an excess metal punching unit. The pressure application unit includes a positioning bed disposed along the rail feet of rails to be welded together, a movable pressure application clamp mechanism provided at one end of the positioning bed and a stationary pressure application clamp mechanism provided at the other end of the positioning bed. The movable clamp mechanism clamps the rail foot of one of the rails and provides an abutting pressure. The stationary clamp mechanism clamps the rail foot of the other rail and receives the abutting pressure. The excess metal punching unit is mounted on the other end of the positioning bed to be fitted on the other rail from the railhead thereof and is capable of being mechanically and detachably coupled to the pressure application unit and is provided with an upper excess metal punching mechanism for punching excess metal off the railheads, rail webs and rail foot upper surfaces of abutted end portions of the rails in one direction. On the other hand, the movable pressure application clamp mechanism is provided with a lower excess metal punching mechanism for punching excess metal off the rail foot lower surfaces of the rails in the other direction opposite to the aforementioned one direction.
