CONSTITUTION:An annular housing 23 is fixed to the under surface 3a of the annular block 3 provided to the lower part of a head unit 1 by a plurality of bolts 24. A plurality of cylinder holes 27 are provided in the annular housing 23 in the peripheral direction thereof and opened to the inner peripheral surface 26 of the housing 23 in an obliquely upward direction. When the pistons 28 inserted in the respective cylinder holes 27 are advanced in an obliquely upward direction, the outer flange 15 provided to the upper part of a die 5 is pressed and fixed to the flange receiving hole 14 provided to the under surface 3a of the block 3 by the clamp jigs 42 fixed to the pistons 28. |
