Dimensional accuracy control method
Process parameter control: In the forging process, by strictly controlling the heating temperature, deformation rate, deformation degree and other process parameters, you can ensure the dimensional accuracy of the crankshaft forging.
Mold design: Reasonable mold design can reduce the deformation and stress concentration in the forging process and improve the dimensional accuracy. The mold should have sufficient stiffness and accuracy to resist deformation under high temperature and high pressure conditions.
Selection of processing equipment: Selecting high-precision and high-stability processing equipment, such as CNC machine tools, machining centers, etc., can ensure the dimensional accuracy of crankshaft forgings.
Measuring method: Adopt advanced measuring methods and measuring equipment, such as coordinate measuring machine, laser scanner, etc., to accurately measure the crankshaft forgings, timely find and deal with the size deviation.
Process parameter optimization: In actual production, through continuous optimization of process parameters, the most suitable heating temperature, deformation rate and deformation degree can be found, so as to improve the dimensional accuracy of crankshaft forgings.
Mold maintenance and update: Regularly maintain and update the mold to ensure the accuracy and stability of the mold and extend the service life of the mold.
Processing equipment maintenance: Regular maintenance and maintenance of processing equipment to ensure the stability and accuracy of equipment, improve the dimensional accuracy of crankshaft forgings.
Measurement data analysis: Through in-depth analysis of the measurement data, we can find out the cause of the dimensional deviation, take timely measures to correct it, and improve the dimensional accuracy of the crankshaft forging.
The dimensional accuracy of Marine crankshaft forgings can be effectively improved by adopting reasonable dimensional accuracy control method and sharing practical experience.
