Abstract

PURPOSE: To prevent the breakdown of a die and to prevent the seizure to the center circular columnar rod of a die by providing the seal for the circular columnar rod at the position corresponding to the partial height of the whole height from the small diameter part of an annular die on the inner periphery thereof.
CONSTITUTION: Rails 10A, 11A are provided at the position in a specific height from the small diameter end of the whole height at the side of a center hole 17 on conical annular dies 2A, 3A and the space with a circular columnar rod 1 is sealed at the time when they are fitted to the rod 1 at the center. The body 4 to be worked is held on the conical outer peripheral face of the dies 2A, 3A, which are pressed in the mutual approaching direction in the space with a host pressure panel 5 by leading in the pressure liquid of the press pressure P1 introduced via a route 21 to the mobile panel 7 consisting of a subordinate pressing cylinder 19 and ram 20. The contact faces 8, 9 of the body 4 to be pressed and the conical outer periphery of the dies 2A, 3A becomes one seal, the pressure liquid of the pipe expanding pressure P2 subjected to a pressure regulation is led via a route 23 into a liquid sealing pressure chamber 12 and this pressure P2 is measured by a pressure gage 24 for controlling.
