摘要： PROBLEM TO BE SOLVED: To eliminate an adjusting mechanism by improving assembling precision of a fixed clamp and a movable clamp. SOLUTION: The machine is provided with a fixed clamp 1 to hold a material P of the one to be pressure welded, a movable clamp 4 to approach/separate to the fixed clamp 1 while holding a material P' of the other to be pressure welded and a cylinder 2 to assemble the fixed clamp 1 and the movable clamp 4. The movable clamp 4, in which a base part 44 is fitted slidably into the inside of the cylinder 2 and an erected part 43 is engaged slidably to a slide groove 3 openingly formed in the axial direction of the cylinder 2. moat part of the fixed clamp 1 and the cylinder 2 are integrated by casting, the slide groove 3 of the cylinder 2 is precisely finished by machining.

摘要： PROBLEM TO BE SOLVED: To simply control the multiple pressure welding capable of the automatic treatment of the material. SOLUTION: A fixed clamp 1 to hold one material P to be pressure welded, and a movable clamp 2 which holds the other material P' to be pressure welded and is brought close to and separated from the fixed clamp 1 are provided. The fixed clamp 1 and the movable clamp 2 are mounted on a movable table 4 which is movable in the same direction as approach and separation, and a temporary clamp 5 capable of temporarily holding the material P is arranged at the extension position in the moving direction outside the movable table 4.

摘要： PROBLEM TO BE SOLVED: To reduce a pressure welding pretreatment time. SOLUTION: This device is provided with a cutting mechanism 4 cutting and forming a pressure welding surface at the end part of materials P, P' to be joined and a grinding mechanism 5 grinding and finishing the pressure welding surface of materials P, P'. The cutting mechanism 4 is arranged and mounted in the upstream side of a transfer line in a base 3 movable so as to advance and retard with respect to the transfer line transferring long sized materials P, P' in a given direction, and the polishing mechanism 5 is arranged and mounted in the downstream side of the transfer line in the same base. The grinding mechanism 5 is provided with an upstream side clamp 5A and a downstream side clamp 5B respectively clamping the material P' locating in the upstream side of the transfer line and the material P locating in the downstream side of the same, and a rotating brush 51 capable of regulating the position along the transfer line, reciprocating perpendicularly to the transfer line and rubbing and grinding the pressure welding surface of materials P, P' is provided between the upstream side clamp 5A and the downstream side 5B of the polishing mechanism 5.
