PURPOSE: A press apparatus for double pressing is provided to weld or cut a workpiece by strongly pressing the workpiece through a second pressing camshaft and a bearing. CONSTITUTION: A press apparatus for double pressing comprises a lifting member(2), a pressing unit(3), and a camshaft drive unit(4). The lifting member comprises upper and lower plates(21,22) and posts(23). The upper and lower plates are vertically moved when a first cam(11) is operated. The posts are vertically inserted into a fixed plate(12) of a support(14) to be vertically movable. The pressing unit moves up and down the lifting member. The camshaft drive unit presses the lifting member. An upper mold(16) fixed to the lower plate of the lifting member presses a workpiece on a lower mold(17) to weld or cut the workpiece.
