Description
Technical field
It is that one kind prevents dust from entering the utility model relates to a kind of whole dustproof construction of steel pipe size reducing machine hydraulic cylinder
Monoblock type dustproof construction inside oil cylinder.
Background technique
Traditional dirt-proof boot the impurity such as is enclosed by sealing shroud, lattice and is accumulated in the trench to outside groove in the prior art
It is squeezed, it could even be possible to sealing ring, lattice are squeezed out out of groove to enclose, scratches inner wall, influence leakproofness, impurity is also kept
Certain moisture increases a possibility that exterior channels one are corroded, while impurity can penetrate into cylinder body hydraulic oil retrogradation is made to block valve
Body causes oil cylinder frequently to be unpicked and washed and is unable to normal use and can seriously oil cylinder be made to scrap.
Summary of the invention
The utility model discloses a kind of whole dustproof constructions of steel pipe size reducing machine hydraulic cylinder, to solve the prior art
Middle impurity dust enters inside oil cylinder, scratches inner wall, influences the problem of leakproofness.
The above-mentioned purpose of the utility model is achieved through the following technical solutions.
A kind of whole dustproof construction of steel pipe size reducing machine hydraulic cylinder, it is characterised in that including：Upper ash stop plate, installation are horizontal
Seat, screw installing hole, lower ash stop plate, the upper ash stop plate of an annular is arranged at the whole dustproof construction top, along its underpart equipped with cross
, there is screw installing hole among horizontal seat, horizontal seat lower part is equipped with the lower ash stop plate of annular, ash stop plate installation on the whole dust cover
Among conical surface set with oil cylinder inner wall, horizontal seat is mounted on top land, lower ash stop plate peace by the screw installing hole among horizontal seat
On the inside of base inner wall.
A kind of whole dustproof construction of steel pipe size reducing machine hydraulic cylinder is an entirety, and material is steel part.
A kind of whole dustproof construction of steel pipe size reducing machine hydraulic cylinder, whole dustproof construction move up and down with piston.
A kind of whole dustproof construction of steel pipe size reducing machine hydraulic cylinder, when piston falls to bottom, upper ash stop plate is fallen to
Conical surface set is intermediate, and when piston rises to top, upper ash stop plate rises to tops on oil cylinder, and dust can be kept off in upper ash stop plate
It is fallen when being opened by grinding tool seat, without droping in the gap of piston and oil cylinder inner wall.
A kind of whole dustproof construction of steel pipe size reducing machine hydraulic cylinder, when piston falls to bottom, ash stop plate is fallen at present
The centre of oil cylinder bottom, when piston rises to top, ash stop plate rises to the middle and upper part of oil cylinder bottom at present, is no more than oil cylinder bottom
Portion, dust directly land out of lower ash stop plate, will not fall into the gap of piston and oil cylinder bottom.
Enter inside oil cylinder by adopting the above-described technical solution, solving impurity dust in the prior art in summary, scrapes
Flower inner wall influences the problem of leakproofness, and directly impurity dust gear is discharged outside cylinder body from other places outside for it, ensure that simultaneously
Internal leakproofness, substantially increases the service life of oil cylinder.
