PURPOSE:To prevent the breakdown of a guide post and guide bush by inserting the guide bush into the guide post with giving a small vibration at least one part of the die. CONSTITUTION:A table 5 is fitted slightly loosely movably via a coil spring 7 to an absorber 6 stood on a foundation 8. On the back face of the table 5 the vibrator 10 of a motor type, etc., is fixed. In the case of assembling the dies of an upper die 1 and lower die 2, the lower die 3 is first mounted on the center of the table 5 and then the handle 11 of the upper die 1 is suspended and the guide bush 4 in all directions is abutted to just above the corresponding guide post 2 to start the vibrator 10. When the guide bush 4 is inserted into the guide post 2 by gradually descending the upper die 1, the insertion is smoothly carried out by the small vibration of the table 5. Consequently the breakdown of the guide post and guide bush is prevented.
