THE RENOVATION AND APPLICATION OF FLEXIBLE DRIVE SYSTEM FOR SLITTING SHEAR AT THE EXIT SECTION OF CONTINUOUS ANNEALING LINE
In the continuous annealing line,the exit slitting shear is mainly used for strip slitting to realize the purpose of sequential switching of coiler winding.Under the conventional electrical start-up control mode,the drive motor of the exit slitting shear has been broken at the front shaft bearing step for many years,resulting in a long unplanned downtime of the production line,which seriously restricts the release of normal capacity.By studying the mechanical structure of the drive device of the exit slitting shear,analyzing the operating characteristics of the exit slitting shear at various stages,and focusing on the problem of impact load on the motor rotor shaft during the starting and shearing phases,the application of flexible drive technology eliminates the problem of motor shaft breakage by the impact load,which not only ensures the stable operation of the continuous annealing line,but also has reference value for the management of similar problems in other production lines.
