Abstract
The utility model discloses a roller system of the four-high cold rolling mil, comprising two backup rolls and the working rolls connecting respectively with the backup roll external surface. Between every two working rolls is a gap for strip passing through and the middle part between every two working rolls is the working segment of the rolled strip, and the two backup rolls and two working rolls are all revolving bodies. Each backup roll connects with the working segment surface in the middle part between the adjacent working rolls of the backup roll, the working segment width being the one of the rolled strip, while between the blend radius segment surfaces at the two ends of the working segment between each backup roll and its adjacent working roll is formed a angle of 1-7 degrees and the working segment and the blend radius segment surfaces at the two ends transits via an arc. The adoption of such a structure of the utility model prolongs the service life of the roller and the bearings of the working rolls, which can produce stable quality rolled products.
Description
Technical field
The utility model relates to 4-roller cold rolling mill, especially relates to the roll roller system of 4-roller cold rolling mill.
Background technology
The roll roller of existing 4-roller cold rolling mill system comprise two backing rolls, with the working roll that each backing roll outer surface contacts respectively, the end of two backing rolls and two working rolls is a bearing, bearing is installed in the bearing block of memorial archway.Has the gap that copper strips passes between two working rolls, the middle part of described two working rolls is the active section of rolling copper strips, there is the soft band section of 40 millimeters long at each backing roll active section two ends, described two backing rolls and two working rolls all are revolving body, each backing roll and each working roll all are cylinder, such structure, because the sag that the effect of roll-force can cause backing roll to form, the soft band section place of each backing roll is easy to generate fatigue deformation, after work a period of time, soft band section outer surface metal peeling occurs and falls the piece phenomenon, it is very undesired that the roll roller of 4-roller cold rolling mill ties up in the use, roll is shorter service life, and the bearing of work roll is fragile, rolling end product quality instability.
The utility model content
Technical problem to be solved in the utility model is: a kind of prolongation roll service life is provided, prolongs the bearing service life of work roll, make the roll roller system of the stable 4-roller cold rolling mill of rolling end product quality.
Solve this technical problem, the technical solution of the utility model is: a kind of roll roller system of 4-roller cold rolling mill, comprise two backing rolls, the working roll that contacts respectively with each backing roll outer surface, has the gap that band passes between two working rolls, the middle part of described two working rolls is the active section of rolled strip, described two backing rolls and two working rolls all are revolving body, the active section surface at the middle part between the working roll that described each backing roll is adjacent contacts, the width of active section is the width of rolled strip, the angle that forms between the rounding section surface at the active section two ends between the working roll that described each backing roll is adjacent is 1～7 degree, and the rounding section outer surface at described active section and its two ends is an arc transition.
The angle that forms between the rounding section surface at the active section two ends between the working roll that described each backing roll is adjacent is 2～5 degree.
Described working roll is a cylinder, and described backing roll is made up of different three sections of diameter, and the stage casing is cylindrical active section, and the two ends of described active section are the rounding section of the frustum of a cone.
The utility model is owing to adopt such structure, the active section of the contacted centre of working roll that backing roll is adjacent is when rolling, because the effect of roll-force, cause backing roll to form sag, the cone angle that active section two ends between backing roll and the working roll form, reduced roll surface edge interaction force between backing roll and the working roll, reduced bending roller force, because bending roller force acts on the working roll bearing block, the active force that bearing in the working roll bearing block bears reduces, prolonged roll service life, prolonged the bearing service life of work roll, the power that acts on band between backing roll and the working roll when mill product is even, and therefore, rolling end product quality is stable.

The specific embodiment
As shown in Figure 1 and Figure 2, a kind of roll roller system of 4-roller cold rolling mill, the end of 2,5 and two working rolls 3,4 of 3,4, two backing rolls of working roll that comprise two backing rolls 2,5, contact respectively with each backing roll 2,5 outer surface is a bearing, and bearing is installed in the bearing block of memorial archway 1.Has the gap that band 6 passes between two working rolls 3,4, the middle part of described two working rolls 3,4 is the active section 7 of rolled strip 6, described two working rolls 3,4 all are cylinder, described two backing rolls 2,5 are formed by three sections, the stage casing is cylindrical active section 7, the two ends of active section 7 are the rounding section 8,9 of the frustum of a cone, and the width of active section is the width of rolled strip.Active section 7 outer surfaces at the middle part between the working roll 3,4 that described each backing roll 2,5 is adjacent contact, the angle that forms between rounding section 8,9 outer surfaces at active section 7 two ends between the working roll 3,4 that described each backing roll 2,5 is adjacent is 1～7 degree, and active section 7 is an arc transition with rounding section 8,9 outer surfaces at its two ends.At this moment, prolong roll service life, prolong the bearing service life of work roll, rolling end product quality is stable.When rolling bronze etc. needs big roll-force, the angle that forms between rounding section 8,9 outer surfaces at the active section two ends between the working roll 3,4 that each backing roll 2,5 is adjacent is 2～5 when spending, and the bearing service life of the service life of roll, work roll, rolling quality of strip all have better improvement.
The roll roller of a kind of 4-roller cold rolling mill of the utility model is that two working rolls 3,4 can also adopt spindle, described two backing rolls 2,5 are formed by three sections, the stage casing is cylindrical active section 7, the two ends of active section 7 are the rounding section 8,9 of the frustum of a cone, the width of active section is the width of rolled strip, and active section 7 is an arc transition with rounding section 8,9 outer surfaces at its two ends.The excessive angle of height and conical surface grinding is level and smooth in adopting like this, processes more convenient.
