The new trend of industry development.Research shows that Vehicle mass reduction is to realize the maximally effective measure of this target.In order to adapt to light weight
The demand for development of change, rolling with varying section plate (Tailor Rolled Blank, TRB) arises at the historic moment.TRB can be according to vehicle body zero
Part difference loaded, the thickness of reasonable layout part.Compared to laser assembly solder plate (TWB), its thickness consecutive variations, without weldering
Seam, with good forming property.Therefore, if bodywork parts are stamped to form by variable cross-section cold-reduced sheet, vehicle can not reduced
Body quality is significantly reduced on the premise of intensity and security performance, and then reduces vehicle unit energy consumption, reduced while energy-conservation
Environmental pollution.
Early stage produce Varied section cold-reduced sheet when use veneer rolling mill practice, low production efficiency, poor product quality, in recent years
Improved production efficiency and product quality progressively to develop to coil rolling direction.
The content of the invention
The utility model is directed to above-mentioned technical problem, proposes a kind of new Varied section cold-reduced sheet rolling device.
To achieve the above objectives, it is achieved through the following technical solutions：、
A kind of Varied section cold-reduced sheet rolling device, including：Coiling machine before machine, milling train, coiling machine and calibrator after machine；Its
In, coiling machine is arranged at milling train input before machine, and coiling machine is arranged at milling train output end after machine, and is rolled up after coiling machine and machine before machine
Machine is taken for conveying band provides front and rear tension force；
Calibrator can be adjusted by travel mechanism before and after the rolling direction along milling train；
The utility model control process using above-mentioned technical proposal is as follows：
Rolled in the case of being processed the front and rear applying hightension of band, tension force is produced by forward and backward coiling machine；
The band forward pull that coiling machine applies after coiling machine and machine before the machine and rolled by milling train under backward pull；
Band is prolonged into rolling direction and is decomposed into several rolling units, each rolling unit is expressed as dx and dy；Dx is phase
For initial point position, dy is thickness of strip；
Each rolling unit dx, dy value are determined by rolling aim curve；
Unit is tracked by way of tracking to the length of strip-rolling, and dx is determined based on band tracking, depresses position
The thickness of strip dy based on dx corresponding units is put to perform；
Calibrator position can be adjusted along rolling direction, and the whole of rolling cycle T is set to apart from L away from milling train center
Several times (L=nT), it is ensured that depressing position and the measurement position uniformity on thickness.
Above several periodic thickness closed-loop control AGC are not put into, and depressing position is determined by presetting depressing position；
After rolling unit reaches calibrator, AGC inputs, Roll-gap position is based on band actual measurement thickness h with setting thickness
Deviation is adjusted.
Using the utility model of above-mentioned technical proposal, integrated model is reasonable in design, and it is reasonable that each mechanism is equipped with, can be high
Effect, the completion cold-reduced sheet work of high-quality.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, and in order to allow above and other purpose of the present utility model, feature
