Abstract
A roller center adjusting structure for four inner rollers of a six-roller cold rolling mill relates to improvement of roller center adjusting structures, solves the problem that sliding parts are easy to abrade while being used for a long time and impurities such as cuttings are generated after the sliding parts are abraded, and prolongs service life of the parts. The four inner rollers are respectively connected with a roller bending balance device arranged on a housing of the six-roller cold rolling mill through adjusting bases of bearing boxes of the four inner rollers, a positioning track protruding the side surface is arranged on the roller bending balance device, the adjusting bases are provided with sliding grooves matched with the positioning track in shape, fixing steel lining plates are arranged on the bottom surfaces and working surfaces on two sides of the sliding grooves, and sliding hard aluminum alloy lining plates are arranged on the top surface and working surfaces on two sides of the positioning track. When rollers of the cold rolling mill are adjusted, the fixing steel lining plates and the sliding hard aluminum alloy lining plates are arranged at relatively sliding positions of working rollers and intermediate rollers, and connection reliability is improved.
Description
Technical field
The utility model relates to six-roll cold mill, relates in particular to the improvement of roll centre adjustment structure.
Background technology
When at the adjustment roller being, cold-rolling mill need do relative motion between the bearing housing of roll and the memorial archway; Generally all adopt copper lining board as sliding part; Though the greasy property of copper lining board is better; But exist the drawback back that is heated easy to wear, need often to change, the wearing and tearing back copper powder that produces has polluted the quality that milling train oil has influenced strip in addition.
Summary of the invention
The utility model is to above problem, provides a kind of and solved that sliding part is long-time to be used easy to wearly, and the wearing and tearing back produces the situation of impurity such as break flour, prolonged four roller roll centres adjustment structure in the six-roll cold mill in service life of part.
The technical scheme of the utility model is: four rollers link to each other with roller bascule on the said six-roll cold mill memorial archway through the adjusting seat of bearing housing separately respectively in said; Said roller bascule is provided with the positioning track of raised side; Said adjusting seat is provided with the chute that matches with said positioning track shape; The working face of said chute bottom surface and both sides is provided with fixedly steel liner plate, and the end face of said positioning track and the working face of both sides are provided with slip duralumin, hard alumin ium alloy liner plate.
Four roller bearing casees link to each other with the adjusting seat in said, and the said working face of regulating seat is provided with fixedly steel liner plate, and the working face of said bearing housing is provided with slip duralumin, hard alumin ium alloy liner plate.
When the utility model at cold-rolling mill adjustment roller is; Because the adjustment amount of working roll and intermediate calender rolls is maximum; The relative motion amount is also just big more; Set up fixedly steel liner plate and slip duralumin, hard alumin ium alloy liner plate at the relative sliding position of working roll and intermediate calender rolls (promptly regulating on the working face of seat and roller bascule, bearing housing), improved the reliability of connection.The utility model has prolonged the service life of part, has improved the quality of product.

The specific embodiment
The utility model is shown in Fig. 1-3; Four rollers (being the upper and lower intermediate calender rolls and upper and lower working roll between the upper and lower backing roll) link to each other with roller bascule 9 on the said six-roll cold mill memorial archway through the adjusting seat of bearing housing separately respectively in said; Said roller bascule 9 is provided with the positioning track 91 of raised side; Said adjusting seat is provided with the chute that matches with said positioning track 91 shapes; The working face of said chute bottom surface and both sides is provided with fixedly steel liner plate i.e. fixedly steel liner plate 22, fixedly steel liner plate 1 and fixing steel liner plate 33, and the end face of said positioning track and the working face of both sides are provided with slip duralumin, hard alumin ium alloy liner plate promptly slide duralumin, hard alumin ium alloy liner plate 26, slip duralumin, hard alumin ium alloy liner plate 1 and slip duralumin, hard alumin ium alloy liner plate 37.
In said four roller bearing casees with regulate seat and link to each other, a said working face of regulating is provided with fixedly the i.e. fixing steel liner plate 44 of steel liner plate, the working face of said bearing housing is provided with the slip duralumin, hard alumin ium alloy liner plate duralumin, hard alumin ium alloy liner plate 48 that promptly slides.
Fig. 2 is respectively to go up intermediate calender rolls 10 and the adjusting seat of top working roll 11 and being connected of roller bascule 9, bearing housing with Fig. 3, has played the adjustment of pair roller core structure.
Fixedly steel liner plate in the utility model adopts No. 45 steel through modified Quenching Treatment; Slip duralumin, hard alumin ium alloy liner plate adopts LC9CS duralumin, hard alumin ium alloy material; This material lubricity after Overheating Treatment is well not easy to wear; Make lubricant effect better through outer apply oil when above-mentioned two kinds of materials are done to slide relatively, more can reduce wear.
