Forming process of locomotive forgings

The forming process of locomotive forgings is the key link to realize the requirement of shape and size in forging process. This paper will introduce the common forming process of locomotive forgings and the importance and concrete steps of equipment debugging to help readers understand and master this key technology.

Locomotive forgings are an important part of locomotive manufacturing, they need to be processed by forming process to achieve the expected shape and size requirements. The choice of forming process and the rationality of equipment debugging are directly related to forging quality and production efficiency. Therefore, it is very important to understand the forming process of locomotive forgings and the methods and steps of equipment debugging for improving the production level of locomotive forgings.

Forming process of locomotive forging:

1. Forging process: Forging is one of the most commonly used forming processes for locomotive forging. It obtains the desired shape by making the metal material undergo plastic deformation in the mold under high temperature and high pressure. Forging can be divided into free forging, die forging and precision forging and other different ways, according to the shape and size of the forging requirements to choose the right forging method.
2. Cold extrusion process: Cold extrusion refers to the process of mechanical extrusion of metal materials to achieve the desired shape and size. Plastic deformation of locomotive forgings can be achieved by cold extrusion, and the density and hardness of materials can be improved. Common cold extrusion processes include drawing, expanding and rolling.
3. Die casting process: Die casting is a process in which liquid or semi-solid metal is injected into the mold by pressure and cooled and solidified under a certain pressure and time. Die casting can produce locomotive forgings with complex shapes and has the advantages of high production efficiency and dimensional accuracy.

The forming process and equipment debugging of locomotive forgings are indispensable links in locomotive manufacturing. Reasonable selection of forming process and equipment debugging can ensure that the dimensional accuracy, surface quality and production efficiency of locomotive forgings meet the expected requirements. By mastering the methods and steps of forming process and equipment debugging, and continuously optimizing and improving the production level of locomotive forgings, it will bring greater impetus to the development of locomotive manufacturing industry.
