Oil hydraulic press

An oil hydraulic press comprising a support frame, at least two main cylinder assemblies, two first fixed die tables and at least one pair of two second fixed die tables disposed in and fixed by the support frame,

• each of the at least two main cylinder assemblies comprises a cylinder body and first and second pistons respectively disposed on two ends of the cylinder body, the first and second pistons are arranged coaxially and move in opposite directions driven by the cylinder body, each of the at least two main cylinder assemblies is coaxially arranged in a line along a telescopic direction of the first and second pistons,
• the support frame comprises two sets of end frames and at least one set of intermediate frames disposed between the two sets of end frames,
• each of the two sets of end frames comprises two first buckle frames coupled to each other, the two first buckle frames are symmetrically arranged around a moving shaft of the respective first piston, one end of each of the two first buckle frames carries the cylinder body of an adjacent main cylinder assembly, the other end of each of the two first buckle frames carries one of the two first fixed die tables,
• the at least one set of intermediate frames comprises two second buckle frames, the two second buckle frames are symmetrically arranged around moving shafts of the second pistons, and two ends of each of the two second buckle frames are respectively connected to the adjacent cylinder bodies,
• the at least one pair of two second fixed die tables connecting with the at least one set of intermediate frames is disposed between the at least two main cylinder assemblies, the at least one pair of two second fixed die tables comprises two second fixed die tables opposite to each other,
• and the at least two main cylinder assemblies cooperate with the two first fixed die tables and the at least one pair of two second fixed die tables respectively, resulting in forming a plurality of pressing mechanisms which are mutually coaxial.
