The production process of agricultural machinery forgings: multi-link precision forging process

As the core component of agricultural machinery, the production process of agricultural machinery forgings is of great significance to ensure the mechanical properties and service life. This paper will introduce the production process of agricultural machinery forgings in detail, including free forging, die forging, ring rolling and other links, as well as the characteristics and applications of related processes.

1. Free forging
   Free forging is a relatively simple forging process in which the raw material is deformed by impact or pressure to form the desired shape and size. The advantages of free forging are simple equipment, high flexibility, and suitable for small batch and multi-variety production. However, the accuracy and efficiency of free forging is relatively low, and it is usually used to produce simpler forgings.
2. Die forging
   Die forging is a process in which a raw material is deformed and formed into a desired shape by means of a mold. The advantages of die forging are high dimensional accuracy, good surface quality, and high production efficiency. Die forging is suitable for the production of large and medium forgings. In the process of die forging, it is necessary to select the appropriate die according to the specific requirements of the forging, and carry out accurate heat treatment and processing.
   Three, rolling rings
   Ring forging is a special ring forging process, which is mainly used to produce large ring forgings. Ring rolling process through rolling and bending processes, so that the raw material to form the required ring parts. Ring rolling process has the advantages of high material utilization rate and high production efficiency, and is widely used in the production of large gear, bearing seat and other parts of agricultural machinery.
   In actual production, according to the requirements of different forgings and production scale, the appropriate process combination can be selected. For example, for small and simple forgings, a combination of free forging and die forging can be used; For large ring forgings, ring rolling process can be used.
   In summary, the production process of agricultural machinery forgings includes free forging, die forging and ring rolling. Each process has its own characteristics and application range, which need to be selected according to specific needs. Mastering these production processes helps to improve the quality and performance of agricultural machinery forgings, and provides strong support for the sustainable development of the agricultural machinery industry.
