Precision forging production is a complex and technically demanding process in which various problems can arise. This paper will discuss the common problems in the production of precision forgings, and put forward the corresponding solutions.
Q&A
Cracks and damage: Forgings may have cracks or damage in the forging process, which is usually due to material problems, too high or too low temperature, uneven forging force and other reasons.
Insufficient dimensional accuracy: Due to equipment accuracy, process parameter fluctuations, die wear and other factors, may lead to insufficient dimensional accuracy of forging parts.
Surface quality defects: such as oxidation, decarburization, folding, burrs, etc., these defects may affect the performance and appearance of the forgings.
Internal defects: such as segregation, porosity, non-metallic inclusions, etc., these defects may seriously affect the mechanical properties and durability of forgings.
solution
Crack and damage solution strategy: First of all, we must strictly control the quality of raw materials and avoid the use of defective materials. Secondly, the forging temperature should be precisely controlled to avoid over-burning caused by too high temperature or cracking caused by too low temperature. Finally, the forging process is optimized to ensure the uniform distribution of forging force and avoid stress concentration.
Improve dimensional accuracy: Production equipment should be regularly maintained and calibrated to ensure that its accuracy is within the acceptable range. At the same time, the process control should be strengthened to reduce the fluctuation of process parameters. For molds, high-quality materials should be used, and timely replacement of severely worn molds.
Improve surface quality: Appropriate protective measures can be taken, such as applying lubricants, using vacuum forging, etc., to reduce surface oxidation and decarbonization. For folding and burr, it can be solved by optimizing mold design and adjusting forging parameters.
Reduce internal organization defects: Reasonable heat treatment should be carried out to improve the internal organization of forgings. In addition, strengthen the detection of raw materials to control the content of non-metallic inclusions in raw materials. Defects such as segregation and porosity can be solved by optimizing the alloy composition and forging process.
Comprehensive measures
Strengthen staff training: improve the skill level and awareness of operators, ensure that they are familiar with the production process and quality requirements of precision forgings, and reduce human error.
Introduction of advanced technology and equipment: The use of advanced production technology and equipment, such as high-precision sensors, advanced control systems, etc., to achieve accurate control and automation of the production process.
Establish a sound quality management system: from the raw materials to the warehouse to the product, each link should be strictly quality inspection and control to ensure the stability and traceability of product quality.
In short, there may be various problems in the production of precision forgings, but as long as the cause of the problem is carefully analyzed, appropriate solution measures are taken, and comprehensive measures are combined to improve and optimize, it can effectively improve the quality and production efficiency of precision forgings, meet the needs of customers, and promote the sustainable development of the precision forgings industry.
