The hydraulic cylinder adjustment device comprises memorial archways, and eight backing rolls, four side supporting rolls, two middle rolls, two working rolls and two supporting rolls are arranged on the memorial archways, wherein the working rolls are supported by the supporting rolls through the middle rolls. Four side supporting devices are arranged on the memorial archways, each side supporting device comprises a backing roll, a side supporting roll and a backing beam, each side supporting roll is supported by two adjacent backing rolls, the backing rolls are installed on the backing beams, and the backing beams are hinged to the middle roll bearing seats through pins. Hydraulic cylinder bases are installed inside the memorial archways, ejection hydraulic cylinders are installed on the hydraulic cylinder bases, and push rods of the ejection hydraulic cylinders abut against the backing beams. The adjustment device has the advantages of being simple in structure, easy to machine and adjust, convenient and fast to maintain, and low in equipment manufacturing cost.
Description
Technical field
The utility model belongs to the plant equipment field, relates to eighteen-high mill, the oil cylinder adjusting device that specifically a kind of eighteen-high mill working roll side supports.
Background technology
Along with the development of Chinese national economy, the requirement of cold rolled stainless steel band, silicon strip constantly increases, and multiple rollers cold calender also is developed rapidly and extensive use.The steel band people such for rolling have developed eighteen-high mill.
Eighteen-high mill at present commonly used is controlled the mode that the side bracing or strutting arrangement advances or retreats, complex structure, and difficulty of processing is large, adjusts, safeguards inconvenience, and equipment manufacturing cost is high.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the oil cylinder adjusting device that provides a kind of eighteen-high mill working roll side simple in structure, ingenious, rational to support, this adjusting device has simple in structure, easily processing, adjustment, convenient, fast while safeguarding, the advantage that equipment manufacturing cost is low.
The technical scheme provided according to the utility model: the oil cylinder adjusting device that a kind of eighteen-high mill working roll side supports, comprise memorial archway, eight backing rollers, four side support roller, two intermediate calender rolls, two working rolls, two backing rolls, wherein working roll is supported by backing roll by intermediate calender rolls, intermediate calender rolls is installed on the intermediate calender rolls bearing block set up between two memorial archways, it is characterized in that: be provided with four side bracing or strutting arrangements on memorial archway, each side bracing or strutting arrangement comprises the backing roller, the side support roller, the backing beam, described side support roller is by two adjacent backing roller supportings, the backing roller is installed on the backing beam, the backing beam is articulated on the intermediate calender rolls bearing block by pin, described memorial archway installed inside has cylinder pedestal, and stretch oil cylinder is installed on cylinder pedestal, and the push rod of stretch oil cylinder withstands on the backing beam.
Further, described side bracing or strutting arrangement is controlled advance and retreat by the stretch oil cylinder with displacement transducer and servo valve.
Compared with prior art, advantage is the utility model: the adjusting device that the utility model side supports adopts servo-cylinder to control, and same backing beam is controlled by two servo-cylinders, can adjust separately, also can adjust simultaneously, and control system is simple; Oil cylinder can be realized moving forward and backward of side bracing or strutting arrangement fast simultaneously, reduces the operating time; Servo-cylinder, with servo valve and displacement transducer, is supported the position moved forward and backward by the computer control side, reduce the manual adjustment time, easy to operate.
