Main and auxiliary connecting rod forging is a common part in the field of mechanical manufacturing, and its quality has an important impact on the performance and service life of the whole mechanical equipment. Production process parameters are one of the key factors affecting the forging quality of main and auxiliary connecting rod. This paper will discuss the influence of production process parameters on quality of main and auxiliary connecting rod forgings.
Temperature is one of the most important parameters in the forging process of main and auxiliary connecting rod. In the forging process, the fluctuation of temperature will affect the plastic deformation and organizational structure of the metal, thus affecting the quality of the forging. Too low temperature may lead to insufficient plastic deformation of metal, resulting in cracks, folding and other defects of forgings; The temperature is too high, may lead to metal overburning, oxidation and other undesirable phenomena. Therefore, precise control of the temperature range is the key to ensure the quality of the forging of the main and auxiliary connecting rod.
Deformation degree and speed are also important factors affecting the forging quality of main and auxiliary connecting rod. In the forging process, the deformation degree and speed of the metal determine the flow and stress distribution of the metal, which affects the microstructure and mechanical properties of the forging. Too small deformation may lead to uneven internal structure of the metal and affect mechanical properties. Excessive deformation may lead to defects such as fracture or excessive deformation of the metal. At the same time, the increase in deformation speed may lead to excessive accumulation of heat inside the metal, causing the metal to overheat or overburn.
Stress and strain are also important process parameters in the production of main and auxiliary link forging. The magnitude and distribution of stress and strain directly affect the macroscopic and microscopic structure of forgings, thus affecting their mechanical properties and stability. In the forging process, the uneven distribution of stress and strain may lead to uneven metal flow, cracking and other problems. In order to improve the quality of the forging of the main and auxiliary connecting rod, it is necessary to control the size and distribution of stress and strain precisely to avoid excessive local stress and strain.
The cooling rate is another key parameter in the forging process of main and auxiliary connecting rod. The cooling rate determines the phase transition process and microstructure of the metal, which affects the mechanical properties and corrosion resistance of the forgings. Too fast cooling speed may lead to thinning of the internal structure of the metal, improve strength and toughness; If the cooling rate is too slow, it may cause the internal structure of the metal to be coarse and reduce the mechanical properties. Therefore, reasonable control of cooling speed is also an important means to ensure the quality of main and auxiliary connecting rod forging.
The post-treatment technology is also one of the factors that affect the forging quality of the main and auxiliary connecting rod. The post-treatment process, including heat treatment and surface treatment, plays an important role in improving the structure and surface quality of forgings. Reasonable post-treatment technology can improve the hardness and wear resistance of main and auxiliary connecting rod forgings, improve their service life and reliability. Therefore, choosing the appropriate post-treatment process is also one of the key steps to produce high-quality main and auxiliary connecting rod forgings.
In summary, production parameters such as temperature control, deformation degree and speed, stress and strain, cooling rate and post-treatment process have important effects on the quality of main and auxiliary link forging. In order to produce high quality connecting rod forgings, it is necessary to precisely control these process parameters to ensure that the plastic deformation, microstructure and mechanical properties of the metal meet the requirements. By optimizing the process parameters and improving the stability of the production process, the quality and reliability of the main and auxiliary connecting rod forging can be improved, and the long-term stable operation of the mechanical equipment can be guaranteed.
