During the rolling process of aluminum alloy, it was easy to have some rolling anomalies such as the material sticking on the guide plate and the billet caught in the clearance between guide plate and die to cause plastic deformation and failure or damage of guide mechanism for cross wedge rolling machine. Due to the long period of repairing or replacing guide mechanism, for protecting the guide mechanism, shortening the maintenance cycle of machine and improving the efficiency and stability of machine and production line, the numerical simulation and design optimization were conducted for the guide mechanism exclusively used for the aluminum alloy cross wedge rolling machine, and the process of billet squeezing into the guide plate was analyzed by the numerical simulation software Deform-3D. Then, the counteracting force when the billet stopped rotating was simulated, and the method for protecting the guide mechanism by safety bolt was put forward. The verified experiment shows that the method is simple and effective. While protecting the guide mechanism, it can detect and timely eliminate the rolling anomalies to resume production and has a certain guiding significance for the design and optimization of the guide mechanism for cross wedge rolling machine.
