Key points of quality control of bearing ring forgings

Bearing ring forgings are the key parts in mechanical equipment, and their quality is directly related to the performance, life and safety of the equipment. Therefore, in the production process of bearing ring forgings, strict quality control is crucial. This paper will focus on the quality control points of bearing ring forgings.

The quality of bearing ring forgings first depends on the quality of raw materials. Therefore, when purchasing raw materials, its chemical composition, mechanical properties, surface quality and other indicators should be strictly controlled to ensure that raw materials meet relevant standards and product requirements. At the same time, the establishment of a sound raw material storage inspection system, strict inspection of each batch of raw materials, to prevent unqualified raw materials into the production link.

The production process is the key factor affecting the quality of bearing ring forgings. In the production process, the process parameters of forging, heat treatment, processing and forming should be strictly controlled to ensure the stability and reliability of the production process. In particular, the forging process should choose the appropriate forging method, forging temperature and forging force to ensure the internal organization and mechanical properties of the forging. In addition, the production process is regularly reviewed and optimized to continuously improve production efficiency and product quality.

The dimensional accuracy and surface quality of bearing ring forgings directly affect the assembly and performance of the equipment. In the production process, advanced processing equipment and testing technology should be used to ensure that the dimensional accuracy and surface quality of the forging meet the design requirements. For critical dimensions, high-precision measuring equipment should be used for testing to ensure that the dimensional tolerance is within the allowable range. At the same time, pay attention to surface quality problems such as surface roughness and oxide skin, and adopt appropriate treatment technology to improve the surface quality of forging.

The internal quality of bearing ring forgings mainly refers to the internal organization, chemical composition and physical properties. These indexes directly affect the mechanical properties and durability of forgings. Therefore, in the production process, metallographic inspection, chemical composition analysis and mechanical properties test should be carried out regularly to ensure that the inherent quality of the forging meets the relevant standards and product requirements. For the problems found, the production process should be adjusted in time to eliminate quality hazards.

The finished product inspection is the last gateway of quality control of bearing ring forgings. In the inspection of the finished product, the appearance, size and internal quality of the forgings should be comprehensively inspected to ensure that the products meet the design requirements and quality standards. For unqualified products, traceability analysis should be carried out to find out the cause and take improvement measures to prevent similar problems from happening again. At the same time, the establishment of a perfect quality file, to achieve product quality traceability, to provide customers with reliable quality assurance.

In short, the quality control of bearing ring forgings is a systematic project, involving raw materials, production process, dimensional accuracy, surface quality, internal quality and other aspects. In order to ensure the stable and reliable quality of bearing ring forgings, enterprises should strengthen quality management, improve the quality control system, improve the quality awareness of employees, and constantly promote the continuous improvement of quality management. Only in this way can we provide customers with high-quality products, win the trust of the market and achieve sustainable development of the enterprise.
