Automation stability improvement method for roll forging unit

Abstract The long shaft forgings in the roll forging forming process and the rigidity of the metal will change due to temperature. When the roller forging clamping device holds the forging piece on one side, the shaft forging piece will be bent due to self-weight, and the height of the other side of the forging piece will be changed, which will affect the operation of forging automation. In this paper, through the statistical analysis of sample data, the relationship between forging temperature and height deviation value is fitted, which solves the problem of how the change in the height of long shaft forgings affects robot handling in the automation process of roll forging. The stability of the forging automation is improved, while the method reduces the investment cost of the production line by using models instead of expensive vision hardware.
