Description
Technical field
The utility model relates to a kind of hydraulic press oil cylinder, is specifically related to a kind of pressure and increases hydraulic press oil cylinder doubly.
Background technique
At present, existing hydraulic press oil cylinder usually by an oil cylinder be installed in an in-oil cylinder piston rod and constitute, according to calculation of pressure formula F=PS; Under the identical situation of fluid pressure, seek out and increase pressure doubly, people can only be through increasing the cross-section area of oil cylinder; The boundary dimension that promptly need add large tank so just makes the overall volume of oil cylinder become huge, and then makes the floor space of oil cylinder enlarge; Manufacture cost and difficulty of processing improve, and the reliability of work reduces.
Summary of the invention
To the deficiency of existing technology, the utility model provides a kind of overall volume less but pressure that obtain increases hydraulic press oil cylinder doubly.
For realizing above-mentioned purpose; The utility model provides a kind of pressure to increase hydraulic press oil cylinder doubly; Comprise a U-shaped master cylinder, be equiped with main cylinder piston-rod in the U-shaped master cylinder, the bottom of U-shaped master cylinder offers the fluid that promotes the main cylinder piston-rod axial stretching and imports and exports; Offer in the described main cylinder piston-rod one with U-shaped master cylinder opening towards consistent U-shaped cavity volume; Axially be equipped with a T shape pressurized cylinder piston bar in the U-shaped cavity volume of said main cylinder piston-rod with one heart, the transverse end of said T shape pressurized cylinder piston bar is positioned at the opening end of main cylinder piston-rod U-shaped cavity volume, and the vertical end of T shape pressurized cylinder piston bar is arranged in the bottom of main cylinder piston-rod U-shaped cavity volume; And be provided with in the vertical end of T shape pressurized cylinder piston bar and be axial vertically disposed oil groove, an end of said oil groove is imported and exported with the fluid of U-shaped master cylinder and is communicated with.
The beneficial effect of the utility model is: adopt said structure; Owing in main cylinder piston-rod, offer a U-shaped cavity volume, in the U-shaped cavity volume of main cylinder piston-rod, install a T shape pressurized cylinder piston bar again, therefore in use; Fluid is is at first imported and exported through the fluid of U-shaped master cylinder and is got into; The promotion main cylinder piston-rod moves, and after main cylinder piston-rod moved, the interior T of promotion of the oil groove shape pressurized cylinder piston bar that fluid flows into T shape pressurized cylinder piston bar again moved along the same direction of main cylinder piston-rod; Thereby under the situation that does not strengthen U-shaped master cylinder boundary dimension; Make oil cylinder obtain to increase pressure doubly, solved existing technology effectively and sought out and increase multiplication of voltage power, must add the technical barrier of large tank boundary dimension.
The utility model can further be set to also be equiped with one heart in the said T shape pressurized cylinder piston bar T shape speedup piston rod; The vertical end of T shape speedup piston rod is arranged in the transverse end of T shape pressurized cylinder piston bar, and the transverse end of T shape speedup piston rod is positioned at outside the U-shaped master cylinder.
Adopt said structure, the utility model is set up a T shape speedup piston rod again in T shape pressurized cylinder piston bar, can accelerate the rate travel of T shape pressurized cylinder piston bar, the pressure that oil cylinder ability synchronization gain T shape pressurized cylinder piston bar and main cylinder piston-rod are produced.
The utility model also can further be set to be provided with seal ring between main cylinder piston-rod and the U-shaped master cylinder, is provided with seal ring between T shape pressurized cylinder piston bar and the main cylinder piston-rod, is provided with seal ring between T shape speedup piston rod and the T shape pressurized cylinder piston bar.
