Quality assurance in manufacturing process of mining machinery forgings
Mining machinery forging is an important equipment component in mining and engineering construction, and its quality directly affects the performance, safety and service life of the equipment. Therefore, in the manufacturing process of mining machinery forgings, quality assurance is very important. Preliminary preparation The preparatory work of manufacturing mining machinery forgings includes technical preparation, site preparation, equipment and personnel preparation. Technical preparation includes detailed study and understanding of product drawings, technical requirements, manufacturing standards, etc., in order to develop reasonable manufacturing programs and processes. Site preparation includes finishing, cleaning and safety measures on the production site to ensure that the production environment meets the specified requirements. Equipment and personnel preparation includes the selection of suitable processing equipment and personnel, and the calibration and maintenance of equipment and personnel to ensure the stability and reliability of the manufacturing process. Material selection Material quality is the key factor to guarantee the quality of mining machinery forgings. When selecting materials, the mechanical properties, chemical composition, physical properties and other indicators should be fully considered. At the same time, according to the product use conditions and manufacturing requirements, the selection of materials that meet the requirements of the standard. In addition, the incoming inspection and storage management of materials also need to be strictly controlled to prevent materials from moisture, rust, damage and other problems affecting product quality. Process planning Process planning is an important link in the manufacturing process of mining machinery forgings. Reasonable process flow should include the formulation of processing specifications, clear precision requirements and quality standards of each process, and specify the inspection process. Processing specifications should specify the selection of processing equipment, cutting parameters, cooling methods and other details. At the same time, we should also develop a sound inspection process, including first inspection, inspection and final inspection, to…
