Description

Lifting four-column oil press Technical Field The utility model relates to the technical field of four-column oil presses, in particular to a lifting four-column oil press. Background The four-column hydraulic press is characterized in that special hydraulic oil is used as a working medium, the hydraulic oil is used as a power source, the hydraulic oil enters an oil cylinder/piston through a hydraulic pipeline by virtue of the action force of the hydraulic pump, then a plurality of groups of sealing elements matched with each other are arranged in the oil cylinder/piston, and the sealing at different positions is different, but the sealing effect is achieved, so that the hydraulic oil cannot leak. The conversion of oil pressure energy into mechanical energy oil pressure transmission is a transmission mode which uses hydraulic pressure to transmit power and control. The oil pressure device consists of an oil pressure pump, an oil pressure cylinder, an oil pressure control valve, an oil pressure auxiliary element and the like; As the application number CN222431706U discloses a lifting four-column oil press and specifically discloses: the centering limiting assembly comprises a U-shaped support fixed on the machine body, a screw rod and a pair of guide rods for guiding are arranged between the left end and the right end of the U-shaped support through bearings, however, in the technology, due to the fact that the object table is inconvenient to detach and install conveniently, when different workpieces are subjected to oil pressure, different clamps are inconvenient to replace, oil pressure efficiency on the different workpieces is low, and therefore practicality of the oil press in use is reduced.
