| Summary: | High-speed cold forming is a complex forming process coupling under multi factors, which has the rolling friction affecting the fluidity of the workpiece metal, and then affecting the quality and performance of the forming parts. In order to understand the variation of temperature field caused by thermal effect, then choose reasonable cold rolling forming parameters to improve product forming quality, the influence of rolling friction is analyzed on the basis of cold rolling forming spline principle. The finite element simulation model is established, which can obtain the variation law of temperature field produced by rolling friction and its influence on forming stress, strain, metal flow and rolling force. It can be the provide reference for cold roll-beating forming precision control. |
