摘要： PURPOSE: To provide a seal welding device which closes the axial bore of a sealing plug having the axial bore in a communicating state with a hollow tube. CONSTITUTION: The welding device 10 has a head 57 to which an end stop member 15 is freely rotatably mounted. The end stop member is movable between an extended position where the front sealing plug engaging the sealing plug is extended for engaging and supporting a sealing plug during welding and a retracted position where the end stop member is retracted. A seal welding electrode 14 is supported in an axial passage of the end stop member. The electrode is movable between a retracted non-welding position where an arc release tip exists in the axial position and an extended welding position where the seal welding of the axial bore is made possible. A drive cylinder 80 as a drive means is connected to the seal welding electrode and the end stop means and the end stop means is retreated to the retracted position and simultaneously the electrode is displaced to the welding position, by which the seal welding is executed.

摘要： PURPOSE: To improve the effectiveness of etching so as to improve the quality of a produced tube by flushing the tube by respectively supplying an acid for etching and washing water to two manifolds covering oppositely positioned open ends. CONSTITUTION: In a tube flush etching and washing station 10, the inside of a tube clamped with tube clamping mechanisms 16A and 16B is etched by flushing the inside of the tube with an acid in one direction through manifolds 20A and 20B. Then the acid is purged by washing the inside of the tube in one direction with water. Then the inside of the tube is again etched by inverting the flow of the acid. Finally, the inside of the tube is washed by making water to flow in the same direction. After washing, the washed tube is moved to a cleaning and drying station 12. At the station 12, the inside of the tube is cleaned by making steam to flow through manifolds 22A and 22B in either one direction after the tube is clamped with clamping mechanisms 18A and 18B. After cleaning, the inside of the tube is dried by making air to flow through the inside.

摘要： A punch press remotely disengageable from the punch drive mechanism, particularly useful where the press must operate in a hostile environment. The press includes a punch block, supporting one or more punches, which is laterally inserted into connection with the punch drive apparatus. A die set is provided for supporting one or more dies, and the die set is associated with the punch block such that the punch is guided into a preselected position relative to the die by the drive apparatus. A structural frame is provided for seating the die set, which can be laterally inserted and removed from the frame. Guide rails are also provided which can extend laterally from the frame and support the die set in a position removed from the normal operating position within the frame. The guide rails also support the die set in the operating position. An hydraulic cylinder can also be provided to laterally eject the guide rails and die set, and the punch block and punch from the frame area, thereby exposing the components for removal.

摘要： PURPOSE: To obtain an ultrasonic tube inspecting apparatus capable of quickly switching for use in the inspection of the tube of various diameter sizes. CONSTITUTION: The ultrasonic tube inspecting apparatus 10 comprises a continous array 14 formed by continously arranging a large number of individual inspecting stations 14A, 14B. The one station 14A is used to inspect the various sizes of the tube irrespective of the tube diameter size. One set of ultrasonic converter assembly is supported at each inspecting station. The assembly of the tube damage inspecting station 14B is disposed in a suitably oriented state corresponding to the diameter size of the specific tube T to be inspected at each inspecting station without necessity of realignment. The station contains the liquid of certain quantity for coupling between the assembly and the tube T for passing the stations 14A, 14B.

摘要： PURPOSE: To make it possible to easily manufacture a low-cost dash pot by connecting a main tube to a sub-tube by welding or bulge joint and providing a flared end at the sub-tube to form a transfer part. CONSTITUTION: The dash pot 82 comprises a tubular lower part 84A of a main hollow tube 84 and a hollow sub-tube 86 inserted into the lower part 84A of the tube 84. The tube 84 has an outer diameter slightly smaller than the inner diameter of the tube 84 to shrink fit the inner surface of the tube 84. The tube 86 has an upper end part 86c having the inner surface of an axial sectional shape extending upward and outward to form a tapered transfer part to connect the both the inner and outer surfaces of the tube 86 to be extended therebetween. The lower end of the tube 86 is mounted at an end plug 88. Thus, the low-cost pot 82 can be easily manufactured.
