Claims

[Scope of utility model registration request]

It is a device that joins overlapping metal plates, resin plates, and other plate-like members by caulking the drawn parts into a flared shape.It is provided on the tip side of the press body so that it can be connected freely, and the periphery of the tip A drawing punch has a widening undercut surface formed at the bottom thereof, a cushion pad that telescopically supports a plate-like member disposed opposite to the drawing punch, and a cushion pad that holds the drawing part of the plate-like member between the parts of the drawing punch. A die with a bottom for receiving the tip, and a dividing die having an inner surface shape corresponding to the undercut surface, and a die with a bottom around the die between a position where the side surface of the drawing area is grasped from the outside and a position where it is removed. It is equipped with a movable caulking die that can be opened and closed freely, and an elastic member that is attached to the movable caulking die and holds the movable caulking die in a closed state before drawing. Joining of plate-shaped members characterized in that the upper and lower surfaces of the movable crimping die are inclined so that the movable crimping die is in a closed state when the lower peripheral portion of the squeezed portion that is pushed down comes into contact with the movable crimping die. Device.
