The Design On Hot Rolled Strip Cutting Shears Automatic Control System

Shears and more used in steel rolling, paper and other industrial production lines. In the rolling billets or small workshop production, shears often placed behind the pass line, mainly used to tie pieces of rolling them into standard length or cut only two ends. Shears in modern industrial production plays an irreplaceable role, flying shear is a movement of objects cut required to achieve a certain degree of cutting precision, and to ensure the speed cutter with the cutting object in the shearing process Synchronize. The development of modern science and technology, and promote the advancement of motion control technology, motion controller enables the control of the shears more stable, accurate and simple.In this paper, flying shear motion control system software design. Analysis of the trajectory of flying shear, flying shear movement proposes using equation algorithm control of the shears, concrete derivation of the algorithm. Analysis and presentation software flow chart of the algorithm implementation. On the hardware platform for motion control flying shear, the system has high control precision, you can change the cutting speed and cutting length, cutting length and enables error control in less than lmm. Aiming hot strip mill with a wire KELK 1780 cutting system to optimize the structure, and presentation for its working principle, the system phenomenon in the actual production of a comprehensive analysis and the presence of a fault to judge policy, focusing on lead analysis and research for various reasons cut errors.
