Flatness of steel strips rolled by the rolling machine for cold rolling of steel strips can be improved.
Description
Technical field
The utility model relates to the steel rolling field, particularly a kind of rolling mill that is used for cold-strip steel.
Background technology
The existing rolling mill that is used for cold-strip steel is not that two-roller mill is exactly a four-high mill, the roll of two-roller mill is made of a pair of upper and lower drive roll that is the rightabout rotation, the roll of four-high mill is made of a pair of upper and lower drive roll and a pair of upper and lower backing roll that is the rightabout rotation, the following weak point of their ubiquities: the strip profile and flatness after 1. rolling (being template) is relatively poor, and horizontal 3 differences or vertical 3 differences can not satisfy the requirement of silicon steel towards the motor stator and rotor; 2. the roller of roll footpath is bigger, so roll-force is bigger, and the power of motor of consumption is bigger; 3. the horizontal axis fixed-site of each roll is constant, when the width of the rolling band steel of want hour, the horizontal axis position of roll can not the adaptive zone steel variation and change, both had influence on the glacing flatness of rolling band steel, easily make the roll two ends produce contact wear again, thereby influence operate as normal, when serious even can have an accident.
Summary of the invention
In order to solve existing in prior technology the problems referred to above, the utility model provides a kind of rolling mill that is used for cold-strip steel, and it can improve the glacing flatness of belt steel rolling.
The purpose of this utility model is achieved through the following technical solutions: a kind of rolling mill that is used for cold-strip steel, it comprises frame, it is characterized in that: be horizontally set with the roll that the following six roots of sensation is arranged parallel to each other on the frame from top to bottom successively: can oscilaltion move and can be around the upper support roller of roll centre line rotation, can again can be to translation around the last intermediate calender rolls of roll centre line rotation along the roll centre bobbin, can only the original place around the last drive roll of roll centre line rotation, can only the original place around the following drive roll of roll centre line rotation, can along the roll centre bobbin to translation again can around the following intermediate calender rolls of roll centre line rotation and can only the original place around the lower support roller of roll centre line rotation; Leave the gap that is used for wearing the band steel between last drive roll and the following drive roll; Also be provided with on the described frame and be used for driving drive roll and following drive roll and be rotary drive mechanism that rightabout rotates, be used for driving the lift drive mechanism that the oscilaltion of upper support roller moves and be used for driving intermediate calender rolls and following intermediate calender rolls is the translational drive mechanism of rightabout axial translation.
Operation principle of the present utility model is described as follows: the band steel is arranged in the gap between drive roll and the following drive roll, driving the band steel by last drive roll that is the rightabout rotation and following drive roll advances, upper and lower backing roll is delivered to upper and lower drive roll by upper and lower intermediate calender rolls with power respectively, thereby the band steel between upper and lower drive roll is rolled.By the lifting position of lift drive mechanism adjustment upper support roller, can adjust roll-force that puts on the band steel and the rolling thickness of being with steel.When the width of band steel changes, go up intermediate calender rolls by the translational drive mechanism drive and be the rightabout axial translation with following intermediate calender rolls, thus the width of adaptive zone steel.
Compared to prior art, the utlity model has following advantage:
(1) can improve the glacing flatness of the band steel after rolling, make horizontal 3 differences or vertical 3 differences satisfy the requirement of silicon steel towards the motor stator and rotor.
(2) owing in the confined space, two rollers or four rolling systems are become six rolling systems, therefore not only reduce the roller footpath of roll, reduce roll-force, thereby the reduction power of motor, and can make the thickness of rolling band steel thinner, can satisfy the rolling requirement of the silicon steel of thickness below 0.5mm.
(3), when the width of band steel changes, can adjust the wide variety that the axial location of upper and lower intermediate calender rolls comes the adaptive zone steel because set up can again can be around the upper and lower intermediate calender rolls of roll centre line rotation to translation along the roll centre bobbin.For example: when the width of the rolling band steel of want hour, can make, following intermediate calender rolls moves respectively vertically round about, on making, the lap of following intermediate calender rolls adapts (as shown in Figure 2) with the width and the position of band steel, so just, can make, the lower support roller is by last, following intermediate calender rolls passes to, the power of following drive roll concentrates on, the middle part of following drive roll (with the band width of steel and the position that the position adapts), thereby prevent, the axial two ends of following drive roll produce contact wear because of flexural deformation, both avoid influencing the glacing flatness of band steel, effectively avoided the generation of accident again.
