Large plate bending rolls control system design
ABSTRACT：late bending rolls is a kind of sheet metal bending into cylinder, vertebral body and curved surface body, or other form of universal molding equipment, has been widely used in boilers, chemical, shipbuilding, aviation, railway transportation and construction industries. With the progress of science and technology, roll-up machine market common defects of low efficiency and low precision, this topic is meant to design high efficient and high precision to intelligent control its large bending roll bending, roll plate. Structure and conducting technical reforming on the plate bending rolls, according to the geometry and mechanical design knowledge to the work roll bending, coiling process working position in mathematical modeling, deduced the work roll in the process of geometric displacement, and then through the PC to the lower place machine realize the precise control of the actuator.
This design USES the PLC + touch screen control scheme, is the upper machine and lower machine control system, is a combination of computer technology, automatic control technology and communication technology of a new type and practical automatic control device, is widely used in industrial control fields, has good stability, high reliability, real-time processing capability, flexible and convenient to operate, easy to programming, etc.
Keywords： Plate bending rolls；electrical control；PLC + touch screen
