摘　　要：在实验室模拟试验和工厂工业性生产试验的基础上，阐述了在多向模锻挤压液压机上实现挤压的工艺特点，找出了分离压余的理想方法——冲切法，给出了冲切间隙的计算方法。为减小挤压型材的弯扭畸变，建立了局部挤压比、挤压带系数的概念。给出了挤压筒中心与挤压模孔型中心距离的计算方法。On the basis of simulation test in the laboratory and production test in the factory, the extrusion specialites on the multi cored forging and extrusion hydraulic press is expounded A better way has been found out, for reminder separation from the extrusion cylinder It is called blanking off method A kind of calculating formulation of blanking clearance is given In order to decrease bend and twist deformation of shape extruded, the new conception of local extrusion ratio and die land ratio is set up, and a new method is got, by which the distance between extrusion cylinder center and die opening center can be calculated
