Sealing and cutting machine shearing process is very complex package mechanical process, which involves elastic deformation, plastic deformation, crack formation, expansion, fracture. In the upper and lower shear blade packaging role in the elastic deformation of the start stage, the billet is elastically deformed. With increasing shear sealing and cutting machine, billet into plastic deformation stage. Severe plastic deformation, cracks began to appear blank surface, followed by crack growth, convergence, fracture separation. When the high-speed packaging fine seal cutting machine cut, the most complex stage is to emerge from the crack fracture. Because at high sealer cut, deformed extremely rapid process, the process can not be stopped in the middle, the middle of the process is difficult to obtain metallurgical samples, the internal deformation mechanism of the material can not know, to cause a great deal of research work difficulties. Also different methods of sealing and cutting machine shearing fracture process is not the same, the quality of the final form of the cross section are not the same.
