Abstract
The utility model provides a novel cold rolling mill working roll bending device. An operation side roll bending hydraulic cylinder is arranged on an operation side arch and can act on an operation side bearing seat of a working roll. A transmission side roll bending hydraulic cylinder is arranged on a transmission side arch and can act on a transmission side bearing seat of the working roll. The operation side roll bending hydraulic cylinder and the transmission side roll bending hydraulic cylinder are respectively provided with a servo valve. The novel cold rolling mill working roll bending device has the advantages that the working roll can be bent forwards and backwards, and the roll bending force of the operation side or the transmission side of the working roll can be adjusted independently, namely the unilateral wave adjustment function is achieved; timeliness and independence of the unilateral wave adjustment in the cold rolling producing process are improved, the strip breakage rate in the steel rolling process is lowered, and production efficiency of a rolling mill is improved.
Description
Technical field
The present invention relates to steel rolling equipment technical field, relate in particular to a kind of Novel cold milling train working-roller bending device.
Background technology
In cold-rolled process, the roller adjustment capability of working roll is adjusted fast response time to template, is regulative mode the most frequently used in rolling process, and roller mode is divided into just curved and negative curved.During existing rolling mill design, adopt the structure of the shared servo valve control of fore side and transmission side, just curved and negative curved when can realize working roll fore side and transmission side.
In the prior art, occur monolateral when wave in high-speed rolling process, existing roll-bending device is because just curved and negative curved when can only realize working roll fore side and transmission side, helpless for independent adjustment one side, can not complete roller task.
Summary of the invention
For the problems referred to above, the problem to be solved in the present invention is to provide a kind of Novel cold milling train working-roller bending device that improves the monolateral unrestrained template regulating measure of milling train and response speed.
Technical scheme of the present invention is as follows:
Novel cold milling train working-roller bending device, the fore side bowed roller hydraulic cylinder that can act on working roll fore side bearing block is installed on fore side memorial archway, the transmission side bowed roller hydraulic cylinder that can act on working roll transmission side bearing block is installed on transmission side memorial archway, described fore side bowed roller hydraulic cylinder with on transmission side bowed roller hydraulic cylinder, be respectively connected a servo valve.
Further, the cross section that ejects end of described fore side bowed roller hydraulic cylinder and transmission side bowed roller hydraulic cylinder is the length direction prolate shape consistent with the direction of working roll center line.
Beneficial effect of the present invention is: owing to adopting technique scheme, can realize working roll simultaneously just curved and negative curved, also can realize the bending roller force of independent adjustment working roll fore side or transmission side, monolateral wave is adjusted function; Improve promptness and independence that in cold-rolling process, monolateral wave is adjusted, reduced the broken belt rate in rolling process, improved milling train production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, working roll 2, fore side bowed roller hydraulic cylinder 3, transmission side bowed roller hydraulic cylinder
4, servo valve
The specific embodiment
Below in conjunction with accompanying drawing, a kind of preferred specific embodiment of the present invention is made to brief description.
As shown in Figure 1:
A kind of Novel cold milling train working-roller bending device, the fore side bowed roller hydraulic cylinder 2 that can act on working roll 1 fore side bearing block is installed on fore side memorial archway, the transmission side bowed roller hydraulic cylinder 3 that can act on working roll 1 transmission side bearing block is installed on transmission side memorial archway, described fore side bowed roller hydraulic cylinder 2 with on transmission side bowed roller hydraulic cylinder 3, be respectively connected a servo valve 4; The cross section that ejects end of described fore side bowed roller hydraulic cylinder 2 and transmission side bowed roller hydraulic cylinder 3 is the length direction prolate shape consistent with the direction of working roll 1 center line.
Described fore side bowed roller hydraulic cylinder 2 with on transmission side bowed roller hydraulic cylinder 3, be respectively connected a servo valve 4, just curved and negative curved when can realize working roll 1 fore side and transmission side, or one-sided roller adjustment.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
