    摘要: A device and a method for axially forming an elongated hollow body is disclosed. The device has at least one receptacle, a reducing die, a punch for pressing the elongated hollow body through the reducing die in the direction of an axis, an expanding mandrel and means for limiting the axial displacement of the punch. The punch and the expanding mandrel are movable on the same axis and the expanding mandrel is arranged inside the punch. The hollow body is reduced to a first diameter in a first portion and expanded to a second diameter in a second portion as a result of a movement of the punch and the expanding mandrel in the same direction.

    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.
