PURPOSE: An oil press is provided to allow a wrench board to be easily detached in an oil press process. CONSTITUTION: An upper supporting board(145) is connected to an oil container(140) surrounding the surface of the upper part of the oil container. A lower supporting board(146) is connected to the oil container surrounding the surface of the lower part of the oil container. A connecting bolt(148) connects a middle board(147) to the upper supporting board in a detachable way. The upper supporting board, the lower supporting board and the oil container are connected to each other in a detachable way. An oil pressure pump provides oil pressure into a main cylinder(130) so that a main piston moves up and down in the main cylinder. |
