diameter clearance
1.In this paper, it was mainly studied the influences of main parameters on flow field in the screw die, including the distance between the damp zone and the screw, the calibration length, the lead of the screw, the width of the screw flight, the boot diameter of the screw, the structure of the screw end, the section area of the side pass, the clearance of the damp zone, etc.
2.Aiming at the defect problem of stock shearing cutting,a comprehensive geometrical analysis of radial clearance,axial clearance,bar diameter,and contact length of cutting edge with the bar,which affect shearing quality in the process of cutting,is presented in this paper where, star ting with the considerationof crack spreading, it is taken as a premise that the cracks formed at the both cutting edges must encounter with each other to ensure cutting quality.
