3. Relevant inspection: measure the surface hardness and hardened layer depth of induction quenching; Metallographic examination was carried out on the hardened layer and its matrix structure.
4. Heat treatment equipment: imported integral quenching machine tools 1 set, 4 domestic integral quenching machine tools and 4 single-tooth quenching machine tools; 12 raceway quenching machine tool. The detection and test center of Maanshan Fiona Fang slewing bearing co., ltd is a comprehensive detection and test center integrating detection, test, research and analysis, aiming to further realize the research and development of detection and test technology for slewing bearings, strengthen product quality control, and provide services and guarantees for the company's product research and development and process innovation.
The testing center is well equipped and the testing methods are scientific and advanced. From the beginning of testing the raw materials of products, the hardness of raw materials is ensured to meet the technical requirements with Kimberly hardness tester. After rough machining, PT flaw detection method is used to eliminate internal defects of metal materials; The length measuring instrument is used to ensure the accuracy of field measuring tools and reduce human error; After the product is finished, the flatness of the mounting surface of the slewing bearing is detected by a laser plane measuring system; Three-coordinate measuring instrument, image measuring instrument, gear pitch tester, gear base pitch tester and electronic roughness tester can comprehensively detect and analyze the static performance of products such as contour, size, parallelism and roughness; Torque test-bed and digital multifunctional test-bed can test the dynamic performance of slewing bearing, such as starting torque and rotating torque. The digital multifunctional test-bed adopts computer automatic control and has the functions of automatic detection, diagnosis and alarm, which can further simulate the operation of slewing bearing under various working conditions, analyze the reliability of slewing bearing and scientifically calculate the life of raceway and gear. The metallographic laboratory is also equipped with advanced physical and chemical inspection equipment such as inverted metallographic microscope, microhardness tester and Rockwell hardness tester, which lays a foundation for controlling and improving the quality and technology of product heat treatment.
Due to the great improvement of testing ability, the number of products that can be tested has increased, and the scope of testing and testing has expanded. Products with improved technology and a large number of new products can be fully tested and verified in the testing center before leaving the factory. Product R&D, design, technology, manufacturing and other departments can continuously optimize and adjust the design, technology and processing technology according to the test results, so as to ensure the ex-factory quality of products and improve customers' satisfaction with the company and products.
With the strong support of the company's sustainable development strategy, the scale of the testing and testing center will be further expanded, and more advanced testing and testing equipment at home and abroad will be continuously introduced according to the needs of product research and development, design, theoretical analysis and process improvement, providing a more reliable basis for product quality and reliability and a reliable guarantee for the technological progress supported by Fiona Fang.
