Abstract

PURPOSE: To devise to attain a disired bellows shape by detecting displacement of each part that is changed at bellows forming time in bulge forming and controlling shaft compressing pressure.
CONSTITUTION: By an oil pressure unit 1, oil pressure is applied to a piston 2, by a stamping part 5, a mandrel 4 and a seal mold 9 are pressed, and at the same time, specified pressure madia is flowed into a supply body 11. Through this, a blank tube 7 is changed to a wave-like form along intervals of separated molds 13, ... which are made narrow following transfer of the seal mold 9, and plural number of bellows 17 are formed. In this forming process, the detector part 15 of a displacement meter 14 always contacts the vertical part of the bellows 17 growing under pressure, detects a degree of its deformation, feeds it back to a control part 16 of shaft compressing pressure, and the blank tube 7 is properly formed without buckling. Further, control of the shaft compressing pressure can be implemented by detecting the pressure of the pressure media applied to a void part 8 or a related value between the stroke position of the piston 3 and the height of the bellows.
