Roll Change Car Of Sheet Rolling Mill Of Cold Rolling Deviation And The Decoupling For Failure Analysis

This paper that cold rolling mill roll change cars of a thin sheet factory for two fault research in the process of operation,It included walking cart snaking and roll change car push carts hook runs,The first detailed descriptions of the plate mill,and detailed introduction in the present situation and development of roller device,Solidworks software 3d model of roll change car was set up, It introduced for each part's structure and work principle,For analysis and push the snaking cart hook decoupling for matting.Now the finite element analysis has become essential in mechanical design of technical means,It has been adopted by the technical staff,This is mainly by ANSYS as analysis platform, it is established roll change car model and analyzed it with ANSYS,According to the analysis and comparison, the results obtained product optimization design.In this paper, the practical engineering problem,According to the scene when replacing roll running deviation for the car roll change,First the paper analyses the factors of running deviation,And according to move transversely frame, one of its non-load carrying roll, and roll change process of three different cases by finite element analysis,Then by finite element analysis of the wheel by analysis ,It points that is due to the wheels by a long time running deviation,According to push carts hook decoupling phenomenon in drag roll process,It analyzed to hook,According to the calculation result and performance,It used double hook device instead of single hook,And instead of hydraulic drive by motor drive,Greatly enhance the clamping force of hook.Avoid effectively the hook decoupling phenomenon,Finally, according to the snaking for designing rectification institutions,Using a mechanical device and electric system combines, It prevent the snaking effectively.Through the exchange roller carts hook model car tyre changes and correction device design,It has important meaning on site equipment maintenance and future improvement of testing equipments,And for the manufacturer provides important reference data,In addition to some design methods in other similar design also has a certain reference value.
