Abstract

The invention discloses an ultra-high-pressure clamping cylinder device, belonging to the field of ultra-high-pressure clamping cylinder devices, comprising a column, a workbench, an oil cylinder block and a piston rod; It is installed inside the oil cylinder body, the worktable is fixedly installed under the oil cylinder body, and the bottom of the piston rod is movably connected with the upper surface of the worktable; the invention adopts the oil cylinder body and the piston rod, and the piston rod is movably sleeved with the oil cylinder body, and uses The guide sleeve seals the piston rod to avoid leakage of hydraulic oil after pressurization, and by filling the ultra-high pressure hydraulic oil into the rodless cavity, the hydraulic oil in the rod cavity between the piston rod and the guide sleeve is discharged. Thus, the piston rod moves downward and clamps the upper end of the worktable. By setting the buffer oil cavity, the buffer oil cavity can absorb a part of the hydraulic oil in the rodless cavity, so as to free up enough time for the hydraulic pump to stop pressurizing. , to avoid excessive force between the piston rod and the worktable, which may cause damage to the equipment.

Description

technical field [0001] The invention relates to the field of ultra-high pressure clamping cylinder devices, in particular to an ultra-high pressure clamping cylinder device. Background technique [0002] The existing hydraulic press mobile table clamping device generally clamps at the lower end of the mobile table, and the clamping force is small, which cannot meet the development trend of the current isothermal forging press with large draft force, and the visibility is poor, and the operation and maintenance are inconvenient. The present invention clamps the plane on the mobile workbench, and the clamping cylinder device is installed on the inner side of the column, and the piston rod goes down or retracts to clamp or loosen the mobile table, with good visibility, convenient operation and maintenance, and large clamping tonnage , fully meet the development requirements of the current isothermal forging press with high draft force. [0003] The clamping force of the existi...
