In fact, many components are processed by the open die manufacturing process. In order to be able to operate the whole process smoothly, the rough forging shape must be realized through the open die forging process, so that the final shape and size of the components can be realized by machining.
It can be seen that the open die forging process can help the open die manufacturing process more efficiently use the raw materials, forging equipment and other available resources, and bring about the improvement of the quality mechanical characteristics and safety operation of the components. So in the process of components manufacturing, what is the positive meaning of the open die forging process?
Usually, the components are formed after the ingot is bloomed into the square billet, saw cutting, roughing, rough machining, heat treatment, semi - finishing, finishing and so on. But the above processes need to realize the rough forging shape through the open die forging process. In other words, the existing components manufacturing method is the combination of open die forging process, machining and heat treatment.
In the open die forging process of large and important components, there is no existing process for forming the near net shape forming. Therefore, an open die forging process needs to be developed for manufacturing complex, large and important components, which will lead to the reduction of input materials, machining operations and cycle time, energy consumption, and ultimately reduce the manufacturing cost.
Practice has proved that, during the large-scale production of this components of the traditional forging method, a large number of raw materials are wasted by traditional manufacturing methods, resulting in a large number of machining time and low productivity. In order to reduce this waste, it is important to make the input near net shape forming to be machined, and this is to be achieved through the open die forging process.
