How does the plate change when Special Tricycle are processed?

In order to make the Special Tricycle smoothly, you need to pay attention to a change in the plate during processing, and its change is mainly like this.

First of all, the rolling change of the plate thickness of Special Tricycle is related to the plasticity of the material, the bottom diameter of the workpiece and the fillet. Reasonable selection of the convex and concave die gaps and fillet radius can increase the plasticity of the material, which can improve the thinning of the plate thickness.
Secondly, when a Special Tricycle is rolled, large plastic deformation occurs, which inevitably causes cold work hardening of the iron plate. The strength and hardness of the sheet material are significantly increased, and the plasticity is reduced, which further increases the difficulty of rolling. The degree of hardening of the sheet material is related to the degree of deformation. In order to control the degree of hardening, the degree of deformation should be reasonably selected based on the plasticity of the material.
However, it should be noted that the high-strength rolled parts of Special Tricycle should be rolled multiple times, and recrystallization annealing treatment is required after each rolling to eliminate hardening after material deformation and prevent the workpiece from cracking during reprocessing.
