Release Time : 2025-02-11
During machining, it is crucial to effectively control the deformation of steel parts to ensure the stability of parts.
Optimize design plan: steel parts During the design stage, the strength and rigidity of the parts should be fully considered to avoid designing overly complex or weak structures. Reasonably arrange the parameters such as wall thickness and aspect ratio of the parts to reduce deformation caused by complex shapes or uneven wall thickness. Apply new technologies, new processes and new materials to reduce internal stress and deformation during manufacturing.
Strict material selection and blank control: Select suitable steel, considering its mechanical properties, heat treatment properties and processing properties. Strictly inspect the blank to ensure that it has no internal defects such as cracks, inclusions, etc. Aging treatment is performed on the blank to eliminate its residual internal stress.
Optimize processing technology: steel parts Develop a reasonable processing route to avoid unnecessary processes and repeated clamping. During processing, adopt appropriate clamping methods and clamping forces to avoid deformation of the workpiece due to improper clamping. Reasonably arrange the processing sequence, first do rough processing, then do fine processing, to reduce the accumulation and release of internal stress. For high-precision parts, artificial aging must be arranged during the fine processing process to further eliminate internal stress.
Use advanced processing technology: steel parts use high-speed cutting processing technology to reduce the impact of cutting heat and cutting force on the workpiece. Use precision processing and micro-machining technology to improve processing accuracy and surface quality. For thin-walled parts, auxiliary supports or reinforcing ribs and other structures can be used to improve their rigidity.
Strengthen process monitoring and detection: During the processing process, regularly inspect the workpiece to promptly detect and correct deformation problems. Use advanced detection equipment and technology, such as three-coordinate measuring machines, laser rangefinders, etc., to ensure the accuracy of the detection results.
Heat treatment and stress control: After the processing is completed, the workpiece is heat treated to eliminate the internal stress generated during the processing. For parts that require special performance requirements, such as high hardness, high wear resistance, etc., quenching, tempering and other heat treatment processes can be used. During the heat treatment process, strictly control parameters such as heating temperature, holding time and cooling rate to avoid deformation of the workpiece.
Improve the operating environment and maintain equipment: Keep the temperature, humidity and other environmental conditions of the processing workshop stable to reduce the deformation of the workpiece caused by environmental changes. Regularly maintain and service the processing equipment to ensure its accuracy and performance are in the best condition.
In summary, by optimizing the design plan, strictly selecting materials and blank control, optimizing the processing technology, adopting advanced processing technology, strengthening process monitoring and testing, heat treatment and stress control, and improving the operating environment and maintaining equipment, the deformation of steel parts during machining can be effectively controlled to ensure the stability of parts.
