Research on the model of the production of hot forming process and the optimization method of production cycle

With the increasingly high demand for energy saving, the demand for lightweight vehicles emerged.Hot stamping of high strength steel is a very important part of automobile lightweight.How to establish an efficient, reliable, energy saving hot stamping production lines will be an integral part of automotive lightweight issues in the production process.Based on the SIGMA hot stamping production line, this paper uses a parallel, multi-scale analysis method and presents an analysis model of production cycle.According to the motion characteristics of industrial robots and transmission principle, the operation steps of industrial robots are mainly analyzed to improve the efficiency of collaborative work.The paper finds production bottlenecks, looks for optimization program to shorten cycle and optimize them, compares the old and new programs and completes the test of feasibility of it, thereby achieves the purpose of improving the efficiency of sheet delivery, shortening the production cycle, and improving production efficiency.
