PURPOSE: A lever cam device of a press for plastic processing of panels is provided to bend the edge of panels easily and to reduce processing and assembling numbers. CONSTITUTION: A lever cam device of a press comprises a cam housing(10), a support(14), a cam base(16), a cam slide(24), a cylinder(32), and a hinge plate(30). The cam housing is mounted on a certain position of a lower die of the press, and an edge side of a panel is placed in the cam housing. The support is mounted on the lower die outside of the cam housing. The cam base has a moving end(18) on the inside end and a rotation center end(20) on the outside end to be hinged on support. The cam slide is assembled to an upper die of the press and bends the edge of the panel. The cylinder is located outside of the cam base, and raises the cam base lowered on its weight. The hinge plate is connected between the cam base and the cylinder, and angle-rotates the cam base to the raised position according to the cylinder driving.
