That is, since the main body 9 and the removable frame 17 positioned relative to the main body 9 are fixed in position by the adsorption action between the magnet 20 and the magnetic body 21, the removable frame 17 relative to the main body 9 can be fixed with a bolt, for example. When positioning and fixing the position of the main body 9, or when fixing the removable frame 17 in the positioned state to the main body 9 using bolts, complicated and time-consuming work such as tightening and loosening of bolts is required. This allows the detachable frame 17 to be easily and quickly attached to and detached from the main body 9, and by providing the detachable frame 17 with the conveying device 4, the movable die 6, and the fixed die 5, the workability of replacing these three parts is improved. , it has become possible to make specification changes even simpler and easier.

Particularly, as in the above embodiment, when using a magnet 20 that can be freely switched between an adsorption action state and an adsorption release state, the adsorption force of the magnet 20 is made strong to strongly fix the position. At the same time, by switching the magnet 20 to the non-adsorption state, the positioning and removal of the detachable frame 17 from the main body 9 can be easily performed without being hindered by the adsorption action.
Can be done quickly.
