The application discloses a rack
online processing method for adaptive reconstruction of a hot rolling new type bending and shifting roller device, a rigid platform is built at a rack window for construction, a mobile boring and milling
machine is used for adaptive reconstruction of the rack, the position of the
machine is finely adjusted to ensure accuracy after the
machine is positioned, high-precision tooling templates for
processing and related equipment for rack reconstruction are provided, a
processing reference is determined according to original state detection data, the rack is processed and reconstructed by taking the rack window surface position of the installation of the balancing bending roller cylinder as the
processing reference, and the balancing bending roller cylinder installation surface, inner and outer upper and lower stop ports, the newly-added outer installation surface of the rack transmission side, the balancing key groove, screw holes and the like are processed; after the machine is processed, the
processing accuracy is detected by using a level and a
laser tracker, and the installation accuracy requirement of the hot rolling new type bending and shifting roller device is met. The method ensures high-precision implementation of the processing operation, improves the processing operation efficiency, saves the equipment reconstruction cost, and further improves the stability and accuracy of rolling of the
rolling mill.
