摘　　要：对称式三辊卷板机增加夹具后,利用有限元法对L型钢滚弯过程进行研究。确定了滚弯过程中夹具工作面之间的距离在t+2-3～t+2-3(mm),通用于L型钢的弯制。避免了参数设定的经验性,提高了生产效率,对生产实践有一定指导意义。After equiping fastening tools in Symmetry Three-roll Bending Plates Machine, the roll bending process of L-strucure steel were reserched with Finite Element Method. It is obtained that the distant between working surfaces of fastening tools is t＋2-3-t＋2-3 （mm） and it is common used in roll bending process of L-strucure steel. This method can avoided the experience parametesr and enhanceed the efficiency of production.
