Abstract
The present invention is a kind of whole dustproof construction of steel pipe size reducing machine hydraulic cylinder, and the quality of dustproof construction is the key factor that can oil cylinder work normally, this entirety dust cover includes：Upper ash stop plate,Horizontal seat is installed,Screw installing hole,Lower ash stop plate,The upper ash stop plate of one annular is arranged at the whole dustproof construction top,Horizontal seat is housed along its underpart,There is screw installing hole among horizontal seat,Horizontal seat lower part is equipped with the lower ash stop plate of annular,Steel pipe necking machine is a kind of bore that the diminution of the bore of waste and old steel pipe can be fabricated to needs,Can all there be cement on waste and old steel pipe,The impurity such as iron rust,Cement when shrinking on steel pipe,The impurity such as iron rust can pass through conical surface set,Oil cylinder,Gap among piston enters in hydraulic oil,Pass through the up and down motion of piston simultaneously,Cement,The impurity such as iron rust also wear oil cylinder inner wall and piston outer wall,The present invention is mounted on top land,As piston moves up and down,When piston rises to top,The top of upper ash stop plate reaches oil cylinder upper cover bottom,When piston drops to bottom,It is intermediate that conical surface set is dropped at the top of upper ash stop plate,The impurity such as dust are fundamentally stopped.
Description
Technical field
The present invention relates to a kind of whole dustproof constructions of steel pipe size reducing machine hydraulic cylinder, and being one kind prevents dust from entering oil cylinder
Internal monoblock type dustproof construction.
Background technology
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 to enclose out of groove, scratches inner wall, influence leakproofness, impurity is also kept
Certain moisture increases the 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.
Invention content
It is miscellaneous in the prior art to solve the invention discloses a kind of whole dustproof construction of steel pipe size reducing machine hydraulic cylinder
Matter dust enters inside oil cylinder, scratches inner wall, influences the problem of leakproofness.
The above-mentioned purpose of the present invention 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 cross seat,
There is the upper ash stop plate of an annular on screw installing hole, lower ash stop plate, the whole dustproof construction top, horizontal seat are housed along its underpart,
There are screw installing hole, horizontal seat lower part that the lower ash stop plate of annular is housed among horizontal seat, ash stop plate is mounted on the whole dust cover
The conical surface is covered among oil cylinder inner wall, and horizontal seat is mounted on top land, lower ash stop plate installation 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 from other places outside cylinder body outside for it, ensure that simultaneously
Internal leakproofness, substantially increases the service life of oil cylinder.

A kind of whole dustproof construction sectional view of steel pipe size reducing machine hydraulic cylinder of Fig. 3 present invention.
Specific implementation mode
The present invention is described further with reference to the accompanying drawings and examples.
A kind of whole dustproof construction of steel pipe size reducing machine hydraulic cylinder as shown in Figure 1, Figure 3, including upper ash stop plate 4, installation
Horizontal seat 2, screw installing hole 3, lower ash stop plate 1, the upper ash stop plate 4 of an annular is arranged at the whole dustproof construction top, along its underpart
Equipped with horizontal seat 2, there is screw installing hole 3 among horizontal seat, horizontal seat lower part is equipped with the lower ash stop plate 1 of annular, on the whole dust cover
Ash stop plate is mounted on conical surface set 5 among oil cylinder inner wall 6, and horizontal seat 2 is mounted on piston 7 by the screw installing hole 3 among horizontal seat
Top, lower ash stop plate 1 are mounted on 8 inner wall of pedestal.
