Claims

[Scope of utility model registration request]

A rail that is equipped with a fixed clamp base fixed on a machine base and a movable clamp base mounted on the machine base so as to be movable in a direction opposite to the fixed clamp base, and that the fixed clamp base and the movable clamp base are to be connected. While grasping the bottom of the rail and abutting the ends of the rails protruding from each clamp stand between both clamp stands and supporting it on the upper part of the machine stand, the movable clamp is heated and melted by a gas burner at the abutting part of the rail and a pressurizing mechanism is used. In a rail gas pressure welding machine that produces a weld by extruding molten metal to the local area of the butt part by moving the table to create a weld,
The machine base is provided with a guide surface parallel to the bottom surface of the rail that communicates between the two clamps, and the movable clamp base is configured to move along the guide surface, and the front part of the movable clamp base is A removable punching tool holder is removably installed, its back is supported on the movable clamp table, its bottom is supported on the guide surface, and its upper surface is brought close to the bottom of the rail, and the punching tool holder is A punching tool is provided parallel to and adjacent to the rail bottom surface across the width direction of the rail bottom surface, and the punching tool has cutting edges at both ends in an arc shape and protrudes forward, and the punching tool equipped holder is The rail gas pressure welding is characterized in that, as the movable clamp table moves, it is moved along the bottom surface of the rail under the guidance of the guide surface, and by this movement, the excess on the bottom surface of the rail immediately after the rail pressure welding is pushed out.
