In order to improve the forging of diesel engine connecting rods, the technology of forging connecting rods in China has been continuously improved. The oil field nut die forgings are prone to produce forging air, and even in the arc of the lever with greater distance and quality problems. At the height and size of the link to the center, from the perspective of the die design process, the connection of several stamping parts has been understood and summarized, and the technical parameters must be selected for common quality problems.

Once the long-term mass production, its experience shows that the design of the die is incorrect. As long as reasonable technical parameters are selected, some common quality problems can be well solved. Through the understanding of the process of pin rail and other die forgings, the program-controlled hydraulic hammer counter is selected as the main forging machine, and the forging manipulator of the medium-frequency induction heating furnace is equipped, as well as other equipment, to form a large forging production line, Process design is carried out according to process flow and equipment parameters. With the development of engineering structure, the requirements for die forgings are becoming higher and higher.
