摘要： PURPOSE:To make a titled device compact and light, by making respective beams of a main part of the device free from generating a bending stress. CONSTITUTION:A pipe 10 to be bent is inserted through a pipe press die 9 as well as is fitted to respective pipe holding dies 2 and 4. A hydraulic jack 7 is stretched to move joints 14 and 16 in the direction of separating the joints 14 and 16 from each other, and respective supporting beams 3 and 5 are turned in the direction of being separated from each other around respective supporting shafts 12 and 13 set as the turning centers. Respective beams 6 and 8 for moving the die 9 and a supporting shaft 24 to which a cross joint is pivotally jointed are moved together in the direction of approaching the jack 7, and the die 9 also moves in the direction of approaching the jack 7 by the cross joint through lock arms 26. Accordingly, a pressing force P is added to the pipe 10, and reactions R1 and R2 are added to the pipe by the dies 14 and 16, to bend the pipe 10.

摘要： PURPOSE:To easily and exactly examine the surface condition of a cylindrical vertical part with high efficiency by a method in which an examining probe is attached to a vertically movable frame while a vertically movable wire and vertically movable annular frame are vertically moved by a drive unit. CONSTITUTION:Three or more vertically movable guide wheels 3 to be touched by the outside of a cylindrical vertical member are attached to the upper and lower parts of a vertically movable annular frame 2 surrounding the member 1 at an interval in the circumferential direction. A vertically movable wire 5 hung down from a drive unit 4 fixed to the upper part of the member 1 is connected to the frame 2 and a number of examining probes facing the outside of the parts 1 are attached to the frame 2 at an interval in the circumferential direction of the frame 2. These probes are vertically moved through the wire 5 and the frame 2 to examine the surface condition of the member 1.

摘要： PURPOSE:To bend a pipe without damaging the surface of the pipe by holding three points of the pipe at equal intervals and giving pressing force to the center and giving reaction force to both sides by extension of a jack. CONSTITUTION:A pipe 11 to be worked is passed through a pipe plunger punch 10 and fitted to pipe receiving dies 7, 9. When a hydraulic jack 1 is extended, jack seats 12, 14 move in the direction to separate from each other and consequently, compression beams 2, 4 turn around pivots 17, 18 in the direction to part from each other. An axis 20 to which plunger punch pulling beams 3, 5 and a cross joint 19 are pivoted moves to approach the hydraulic jack 1. At the same time, the pipe plunger punch 10 is moved to approach the hydraulic jack 1 by the cross joint 19 through clamp arms 21, 22. Thus, pressing force is given to the pipe 11 by the pipe plunger punch 10 and reaction force is given by pipe receiving dies 7, 9, and the pipe 11 is bent.
