Claims

[Scope of utility model registration request]

A series of first, second, and third slide stands that reciprocate appropriately in a section regulated by a stopper along a common slide guide, and the first and third slide stands at both ends are integrally connected. a connecting member, a third slide base and an intermediate second
a drive source that reciprocates the slide tables in opposite directions via a toggle mechanism; a pair of press dies that are removably attached to the first and second slide tables; A pair of fluid pressure cylinders that selectively applies a required braking force to one of the press molds to extend the priority order of operation of the pair of press dies, and a switching valve that switches the supply of fluid to the fluid pressure cylinders. A press device characterized by:
