The quality standards of agricultural machinery forgings include the following aspects: size and tolerance: the size of agricultural machinery forgings should meet the design requirements, and be controlled within a certain tolerance range to ensure the reliability of coordination with other parts and assembly. Range and position tolerances: There are some special shape, edge and surface features on agricultural machinery forgings, and range and position tolerances require that these features be clearly specified. Surface quality: The surface of agricultural machinery forgings should be smooth, no cracks, no scars or other defects. For different application environments, such as corrosion resistance, wear resistance and other special needs, there may also be special surface treatment requirements. Basic mechanical properties: Agricultural machinery forgings should have the required strength, hardness, toughness and other mechanical properties to meet the requirements of agricultural machinery work. These properties can be evaluated by chemical composition analysis, physical testing, and mechanical property testing. Reliability and life: Agricultural machinery forgings need to have good reliability and service life to ensure that there is no rupture, deformation and failure during long-term use. Testing requirements: The quality standard of agricultural machinery forgings also includes testing requirements, specifying the testing items and methods that must be carried out, such as non-destructive testing, chemical composition analysis, metallographic structure analysis, etc. The quality standards of agricultural machinery forgings are usually formulated by national standards, industry standards or enterprise standards to ensure that the performance and quality of forgings in the design, manufacturing and use process meet the requirements. In the production process, the corresponding standards need to be followed for quality control and inspection to ensure that agricultural machinery forgings reach the expected quality level.
