As the core parts of the engine, the production equipment and technical requirements of the main and auxiliary connecting rod forging directly determine the quality and performance of the forging. This paper will introduce the production equipment and technical requirements of the main and auxiliary link forging in detail to ensure the high efficiency, accuracy and stability of the forging production.
Production equipment
Heating equipment: In order to ensure that the material is uniformly heated to the appropriate temperature, electric induction heating furnaces or gas heating furnaces are usually used. These devices are characterized by fast, uniform heating and can effectively control oxidation and decarbonization during heating.
Forging equipment: The forging of main and auxiliary connecting rod forgings is usually done by hydraulic press, mechanical press or hammer forging machine. These devices can provide enough forging force to ensure that the material is fully deformed during forging to achieve the desired shape and size.
Molds and tooling: Special molds and tooling are needed in the forging process to ensure the accuracy and consistency of the forging. Molds are usually made of high-strength alloy steel, which is precision machined and heat treated to ensure their wear resistance and service life.
Cutting and finishing equipment: After forging is completed, the forgings need to be cut and trimmed using a flame cutting machine, a laser cutting machine or a plasma cutting machine to remove excess metal and achieve the final size requirements.
Testing and testing equipment: In order to ensure the quality of forgings, various testing and testing equipment need to be used in the production process, such as metallographic microscope, hardness tester, ultrasonic flaw detector, etc., to carry out a comprehensive inspection of the internal organization, mechanical properties and surface quality of forgings.
Technical requirement
Material requirements: The material of the main and auxiliary connecting rod forging should meet the relevant standards, and have good malleability, mechanical properties and corrosion resistance. The chemical composition and mechanical properties of the material shall be strictly tested to ensure that they meet the design requirements.
Heating and forging process: The heating temperature and holding time should be precisely controlled according to the nature of the material and the requirements of the forging. The forging process should ensure that the material is fully deformed and the mold cavity is filled, while avoiding material damage caused by excessive forging.
Size and shape accuracy: The size and shape of the forging should meet the design requirements to ensure an accurate fit with other parts of the engine. The accuracy of the mold and tooling should meet the requirements of forging accuracy, while considering the shrinkage rate and deformation of the material.
Surface quality: The surface of the forging should be smooth, no cracks, pores and other defects. Heat-affected zones and mechanical damage should be avoided during cutting and trimming.
Testing and testing: Comprehensive testing and testing of forgings should be carried out in the production process, including chemical composition analysis, mechanical properties testing, non-destructive testing, etc. Ensure quality of forgings meets relevant standards and customer requirements.
In summary, the production equipment and technical requirements of the main and auxiliary connecting rod forging are crucial to the quality and performance of the forging. By selecting appropriate production equipment, optimizing process parameters and strict quality control, high quality main and auxiliary connecting rod forging can be produced to meet the performance and use requirements of the engine.
