STUDY OF THE PROCESS OF BREAKING ROLLED STEEL BY BENDING FOR STAMPING UNDER IMPACT AND COMBINED LOADING

Abstract

At the present stage of mechanical engineering development, the problem of energy resources and metal economical use during its processing specifies ever increasing requirements to technology and equipment for separating raw materials into workpieces. This requires the development of already known and the creation of new effective separation processes and equipment for their implementation1. At every engineering enterprise, the rolled stock separating is typical and massive. Considering that ten millions of workpieces from rolled stock are produced every month in the world, the relevance of works aimed at improving the existing and developing new technologies for the production of workpieces becomes evident. Among the known methods of separating of rolled stock into dimensional workpieces, used in modern procurement production, the most productive and economical ones are waste-free methods of separating rolled stock. They are cutting by shearing and cold breaking by bending.
