Reform Of Continuous Shear In Finish Rolling

Finish rolling shear is the key equipment of wire rods producing 1ine, while cutshead and end of rolled piece, so that the rolling line is smooth, and the quality ofproduCts is imProved.Recently high-speed wire rod line adopts stat-stop shear But Pan Gang wire rodsplani makes use of coniinuous tUndng round shear,ths doesn't meet process demandsafter refOrm in l999.Therefore the refOrm was suggested that changed the contnuous shear into thested-stop shear That is, rctaining the gear driving of the continuous sheap and adding toa middle reduction device, and choosing a direct currCni motor again, and tdeng theplace of the relay analogUe coin1ling system for the comPuter controlling digitalsystem.This project was taken in 9.l999, Through practice about a half year it showedthat it's reliabilities and precision caxne uP to inirmational technology level.Ths paPer system intrOduce the general principles of stat-stop shear It isdescribed that the speeds of starstop shear to the drive .the choice of the motof,theprinciples of the sted-stop shear's cothelling, the theory of site-colltrOlling, and theconstrUction of mathematics-model.This paPer's main idea comes frOm the practice. We realize the reform ofcontnuous shear and resolve the problems of the producing development on conditionsof using the 1east invesAnent and the shortest time. Ths paPer Provides a new idea ofimproving shear's ability and reducing the investrnent of project.
