摘要： A roller width adjusting device for a divided molding roller has a hollow main shaft journalled at each end to side bearings so as to be rotatable around a rotary axis thereof. The hollow main shaft is connected at one end to a driving source for rotating the main shaft around the rotary axis. A pair of hollow cylindrical roller holders are disposed on an outer periphery of intermediate portions of the main shaft so as to be slidable along the rotary axis of the main shaft. The roller holders may be fixed in any position along the rotary axis by a holding device. A pair of divided type molding rollers are attached to the roller holders, respectively. An adjusting shaft is rotatably disposed in the hollow shaft along its rotary axis. Each end of the adjusting shaft has a screw thread with opposed screw directions. One end of the adjusting shaft has a rotatable handle. By rotating the handle in one direction the interval between divided rollers is increased thus moving the roller holders farther apart; whereas by rotating the handle in the other direction the interval is decreased thus drawing the roller holders closer together. Once in position, the divided rollers are slidably fixed by the holding device such that pipe of that particular size can be manufactured.

摘要： There are provided a high dimensional accuracy pipe and a manufacturing method thereof, the pipe being in response to wide requirements of sizes, being manufactured at inexpensive cost, and having a sufficient fatigue strength. The detailed structure thereof is as follows. A push-to-pass process is performed in which, while a plug 1 is being charged in a metal pipe 5, the metal pipe is pushed in a hole provided in a die 2 and is then allowed to pass therethrough. As a result, a high dimensional accuracy pipe can be obtained in which at least one of the deviation of the outer diameter, the deviation of the inner diameter, and the deviation of the thickness in the circumferential direction is 3.0% or less as processed.
