摘要： In a Turk's head stand for adjusting positions of whole four-way straightening rolls in both vertical and horizontal directions in a state where the four-way straightening rolls are mounted at predetermined positions, a stack body of roll chocks and yokes can be exchanged by withdrawing it from the stand in a direction perpendicular to a product proceeding direction. For this purpose, double inner frames are disposed inside an outer frame. A first inner frame is disposed so as to be adjusted only in the vertical direction, and a second inner frame is disposed so as to be adjusted only in the horizontal direction. The four-way straightening rolls and position adjusting devices are incorporated inside the second inner frame. Mechanical structures for convexo-concave engagement are disposed on faces of the respective roll chocks and yokes and the inner frames opposed to each other, thereby to guide the respective roll chocks and yokes, by utilizing descending motions of the inner frames, after connection with a pressing device has been released, to form the stack body in series, and to enable the stack body to be withdrawn from the roll stand. Then, by utilizing ascending motions of the inner frames, the stack body is disassembled, and the respective roll chocks and yokes can be guided to desired positions in the stand to be locked.

摘要： The present invention provides a compact tube clamping device 50 with a simple structure and used suitably for a hydraulic pressure tester for inspecting quality of an electric resistance welded tube. To achieve this object, a lifting/lowering base 52 including a tube support body 55 on itself is provided onto a fixed base 51 to be able to lift and lower. Clamp claws 56 are mounted in positions, between which the tube support body 55 of the lifting/lowering base 52 is sandwiched, to be able to turn. A claw drive body 58 for lifting and lowering independently of the lifting/lowering base 52 is provided in the lifting/lowering base 52. Opposite side portions of the claw drive body 58 are connected to the opposite clamp claws 56 by links 59 so as to turn the opposite clamp claws 56 in closing directions by lowering with respect to the lifting/lowering base 52. Both of a first drive mechanism 53 for driving the lifting/lowering base 52 for lifting and lowering and a second drive body 54 for driving the claw drive body 58 for lifting and lowering are provided to the fixed base 51. Because a lowering stroke of the claw drive body 58 necessary for closing operations of the clamp claws 56 is partially born by lifting of the lifting/lowering base 52 in transferring the tube, the lowering stroke of the claw drive body 58 for opening and closing the clamp claws 56 can be suppressed.

摘要： To provide a pipe cutting machine capable of cutting a pipe even of a large diameter efficiently in a short period of time, and achieving excellent economical efficiency and excellent durability with a simple, compact, and light-weight configuration.
A pipe cutting machine cuts a pipe 10 at a right angle to the center line of the pipe 10. The pipe cutting machine comprises: rotary blades 20, 20 in a pair, with a plane at a right angle to the center line of the pipe 10 to be cut defined as an x-y plane and the center of the pipe 10 defined as a coordinate origin, the rotary blades being arranged to face each other on both sides of a y axis in such a manner that blade edges of the rotary blades 20, 20 overlap each other in the direction of an x axis; a straightforward driving mechanism 50 that drives the rotary blades 20, 20 in a pair straightforward in opposite directions of a y-axis direction so as to make the rotary blades 20, 20 in a pair pass each other on the x axis and in the vicinity of the x axis; and a power direction conversion mechanism 46 and a power direction conversion mechanism 47 that change part of straightforward driving force in the y-axis direction to force in the x-axis direction and move the rotary blades 20, 20 in a pair outwardly to get farther from the y axis for avoiding interference between the blade edges when the rotary blades 20, 20 in a pair pass each other on the x axis and in the vicinity of the x axis.-

摘要： There is provided a forming apparatus having a simple and compact structure in which rolls can be easily exchanged, without mounting a hydraulic actuator or the like for forming or disassembling a stack body of roll chocks and yokes on inner frames or a roll stand, for the purpose of enabling the rolls to be exchanged, by withdrawing the stack body from a forming roll stand in a direction perpendicular to a product proceeding direction. For realizing this, the inner frames are arranged in the forming roll stand so as to move up and down. Mechanical structures of convexo-concave engagement are provided on opposed faces between the respective roll chocks and yokes and the inner frames. After connection with a pressing device is released, the roll chocks and yokes are guided utilizing the moving-downward motion of the inner frames, and the stack body is formed in series so as to be withdrawn from the roll stand. The stack body is disassembled utilizing the moving-upward motion of the inner frames, and the roll chocks and yokes can be guided to the desired positions inside the stand and locked.
