Abstract
The present invention discloses a hydraulic roll bending equipment, in the concrete, it is a hydraulic roll bending equipment which can be used for regulating gap between two working rolls of rolling mill. Said hydraulic roll bending equipment is composed of the following several portions: seat body, upper hydraulic cylinder, lower hydraulic cylinder, upper piston, lower piston, upper piston rod, lower piston rod, upper hydraulic cavity, lower hydraulic cavity, upper pressure cover and lower pressure cover. Said invention also provides the connection mode of all the above-mentioned portions and the concrete operation method of said hydraulic roll bending equipment.
Description
Technical field
The present invention relates to a kind of hydraulic means.Specifically, be the hydraulic roller-bending device that is used for adjusting gap between two working rolls of milling train.
Background technology
All know in the milling train manufacturing, during milling train work, its pressure concentrates on the two ends of two backing rolls and double-working, make double-working two ends with fitted by strip tighter, and their centre and the pine of being fitted by strip, the band thick middle that shuts out, both sides are thin, both sides with middle 3 between formation radian tolerance, second-rate.For addressing this problem, conventional method is with manually grinding being carried out at the working roll two ends, being made working roll form radian tolerance small in ends, broad in the middle.Though adopt this method can solve the thin problem of thick middle, both sides of band, not only time-consuming more, the inefficiency of grinding roller, and precision is difficult to guarantee still is difficult to guarantee the quality by strip.
Background technology
The problem to be solved in the present invention provides a kind of hydraulic roller-bending device.Adopt the milling train of this hydraulic roller-bending device, the band precision height, the quality that not only roll out are good, and can increase work efficiency.
For addressing the above problem, take following technical scheme:
Hydraulic roller-bending device characteristics of the present invention are to comprise pedestal, have last hydraulic cylinder and following hydraulic cylinder, the piston rod of upper and lower hydraulic pressure to be on the same axis on the pedestal and their overhanging end is distinguished up and down.Last hydraulic cylinder wherein and following hydraulic cylinder contain hydraulic cavities and lower hydraulic pressure chamber respectively.Should go up hydraulic cavities and lower hydraulic pressure chamber and be on pedestal and below processing blind hole and forming, upper piston and upper piston rod and lower piston and lower piston rod are arranged respectively in it, their oral area has upper press cover and lower cover respectively, centre bore is all arranged on upper press cover and the lower cover, and the overhanging end of upper piston rod and lower piston rod stretches out respectively outside the centre bore of upper press cover and lower cover.
Take such scheme, have the following advantages:
Because hydraulic roller-bending device of the present invention comprises pedestal, last hydraulic cylinder and following hydraulic cylinder are arranged on the pedestal, the piston rod of upper and lower hydraulic cylinder is on the same axis and their overhanging end is distinguished up and down.Under the user mode, between the double-working two ends of milling train hydraulic roller-bending device of the present invention is installed all, and the piston rod overhanging end that makes upper and lower hydraulic cylinder withstands on the two end axles bearing of double-working, make two ends micro-up and down perk respectively, the roll surface of top working roll and bottom working roll form the radian tolerance, thereby solved by rolling sheets thick middle, the thin problem in both sides, made the board quality that shuts out improve greatly.Again owing to utilize the piston rod overhanging end of upper and lower hydraulic cylinder to withstand on the two end axles bearing of double-working, make two ends micro-up and down perk respectively, the roll surface of top working roll and bottom working roll form the radian tolerance, solve by rolling sheets thick middle, the thin problem in both sides, compare with traditional grinding roller two ends, can save time, increase work efficiency.
Description of drawings
Accompanying drawing is a hydraulic roller-bending device structural representation of the present invention.
The specific embodiment
As depicted in figs. 1 and 2, hydraulic roller-bending device of the present invention comprises pedestal 3, this pedestal is a cuboid, be processed with hydraulic cavities 6 and lower hydraulic pressure chamber 10 on its above and below respectively, be separately installed with upper piston 7 and upper piston rod 5 and lower piston 8 and lower piston rod 9 in last hydraulic cavities 6 and the lower hydraulic pressure chamber 10, their oral area is fixed with upper press cover 4 and lower cover 11 respectively, all be processed with centre bore on upper press cover 4 and the lower cover 11, the overhanging end of upper piston rod 5 and lower piston rod 9 stretches out outside upper press cover 4 and lower cover 11 by the centre bore of upper press cover 4 and lower cover 11 respectively.Thereby form hydraulic cylinder by last hydraulic cavities 6, upper piston 7 and upper piston rod 5 and upper press cover 4, form hydraulic cylinder down by lower hydraulic pressure chamber 10, lower piston 8 and lower piston rod 9 and lower cover 11.Upper piston rod 5 wherein, lower piston rod 9 are on the same axis and their overhanging end is distinguished up and down, they all parallel with the length direction of cuboid pedestal 3.
Fix for ease of bearing block with the operation roll of mill two ends, a rectangle face bottom and upper segment at pedestal 3 all is processed with chimb 1, be processed with on the chimb 1 and be convenient to the through hole 2 that links to each other with milling train, hydraulic roller-bending device of the present invention can be fixed between the bearing block at operation roll of mill two ends by bolt and this through hole.
By making upper piston rod 5 and lower piston rod 9 overhanging, can make the top working roll of milling train and two ends micro-up and down perk respectively, the roll surface of bottom working roll form the radian tolerance, can overcome by rolling sheets thick middle, the thin problem in both sides, make the board quality that shuts out improve greatly.
