METHOD AND APPARATUS FOR MANUFACTURING TIGHTENING JOINT MEMBER

PROBLEM TO BE SOLVED: To provide a method for manufacturing a tightening joint member, capable of generating a prescribed load by adjusting a position, and realizing time reduction for the position adjustment. SOLUTION: This method is to manufacture the tightening joint member 9a which includes a housing 92 having an accommodating hole 92a for accommodating a fluid pressure generating member 91, an energizing means 93 sandwiched by the member 91 and the accommodating hole 92a for energizing the member 91, and a screw member 94 which can be jointed and fixed at the accommodating hole 92a, and which screws and fixes the screw member 94 to the housing 92 so that the supporting force of the energizing means 93 may become a prescribed supporting load. The method has a press process I of switching a press speed from a prescribed high speed to a prescribed low speed corresponding to a press load while the member 91 is pressed by a press means 2 to apply the prescribed press load P1 to the press means 2, and a tightening process II of switching a tightening speed from the prescribed high speed to the prescribed low speed corresponding to a change in the load P1 and subtracting a prescribed load ΔP from the load P1.
