Technical background
Processing for modern aluminum volume is all generally to control the thickness that aluminium is rolled up using hydraulic bending roll.Its operation principle is to utilize
Hydraulic bending roll cylinder makes working roll or support roller produce addition bend deformation, compensates due to roll-force, rolling temperature, incoming profile
Etc. it is a variety of caused by roll gap change, to obtain good plate shape.Hydraulic bending roll typically uses hydraulic servocontrol, has response
The characteristics of speed is fast, control accuracy is high.The use of hydraulic bending roll can reduce roll grinding roller and roll change number, improve the plate of milling train
Shape control ability, improve the production efficiency of cold-rolling mill.Therefore, hydraulic roller-bending device plays highly important in whole cold-rolling mill
Effect, is directly related to normal operation and the operation of cold-rolling mill.In hydraulic roller-bending device, roll-bending cylinder is wherein highly important
One of part.Traditional roll-bending cylinder is sealed between piston and cylinder body using simple O-ring, living because O-ring seals
It is not oriented between stopper rod and piston, the gap between piston and cylinder body, piston rod and gland is difficult to be effectively sealed, and is added
Single facing-up can only be carried out during work, processes trouble, the sealing effectiveness of O-ring is very poor, is transported up and down repeatedly in piston
, there is polluted rolling oil in the phenomenon of the existing oil spilling of remittance abroad in capable process, has a strong impact on that aluminium rolls up the quality in the operation of rolling.
The content of the invention
The technical problem to be solved in the invention is a kind of aluminium volume processing cold-rolling mill proposed for above-mentioned technical problem
Two way seal roller cylinder structure, processing is simple and convenient, effectively realizes two way seal effect using T-shaped sealing ring, ensures moment of flexure cylinder
Positive production operation, improve aluminium volume the quality of production.
In order to solve the above technical problems, the invention provides a kind of aluminium to roll up processing cold-rolling mill two way seal roll-bending cylinder knot
Structure, mainly it is made up of cylinder body, gland, piston rod, piston, the first sealing ring, the second sealing ring, dust ring and sealing shroud；It is described
The lower end of piston rod is fixedly connected with piston, and the sealing shroud is set on piston, and the piston is slidably arranged in cylinder body, described
The second sealing ring is additionally provided with cylinder body, the upper end of the cylinder body is fixedly installed gland, and the gland is arranged on the piston rod,
Dust ring and the first sealing ring are provided with the inside of the gland；The cross section of first sealing ring is trapezoidal.
Further, in above-mentioned technical proposal, the cross section of first sealing ring uses isosceles trapezoid, and described first is close
The upper bottom length of seal is 1~3mm, and the bottom length of first sealing ring is 4~8mm, the height of first sealing ring
For 1~4mm.Such design can effectively ensure up and down motion of the piston rod in oil cylinder, using such two-sided gradient
Sealing ring can effectively play the effect of sealing, also ensure that the sealed connection in installation process.
Further, in above-mentioned technical proposal, distance is 5~8mm between the first sealing ring tripping base portion.So
Design be to strengthen the sealing effectiveness of seal, prevent from being carried over during fluid is lower mobile on the piston rod.
Further, in above-mentioned technical proposal, guide ring is additionally provided between the piston rod and cylinder body.Such design
The even running of piston rod can be ensured, reduce the excessive danger of fluid, the operating efficiency of roller is improved, so as to protect on the whole
Demonstrate,prove the production efficiency of cold-rolling mill.
After said structure, processing is simple and convenient, effectively realizes two way seal effect using T-shaped sealing ring, ensures curved
The positive production operation of square cylinder, improve the quality of production of aluminium volume.
