Dynamics Analysis Of Sizing Press

It is important to adjust the casting slab width on the rolling product line. In some sense, it's a vital on the continual rolling and in volume-produce of working. Sizing pressing which IHI explored in the 80's of the previous century was imported by Bao steel in the thermal rolling at 1996. It's significant to enlarge the category and increase yield.This thesis based on the exploitation agreement that Bao Steel company signed with Yanshan university , analyzed the movement ,dynamics and load character of sizing pressing, in addition analyzed the deform of slab ,at last research the load of the important component. The result of the research was important to hold dynamic characteristic and maintenance equipment.The mechanism of sizing pressing was simplified to have eight rod and three freedom. The paper found mathematic model of movement on the vector equation, realized the variety disciplinarian of the displacement, velocity and acceleration. The simulate result is consistent with result testing.The paper found the FEM model that the hammerhead presses the slab afterward analyzed the disciplinarian of stress, strain and the metal flowing velocity on the course of the continual rolling. It is significant to research the rolling theory and optimize the product technics. At the same time, analyzed the reason that brought the dog bone; analyzed the force that slab impacts on the hammerhead by researching the contact problem. The result establishes the foundation that study the force on the important accessory.Basing on the mechanism dynamics, founding the rigid model of the rigid and flexibility body. Comparing the simulate result with testing result, the flexibility model is rather than the model of rigid body. Based on the flexibility model, the paper studies the force on the joint and import accessory. At last, analyses the force and the libration of brace bearing ,at the same time calculated the life of the bearing.
