Optimization Method for Heat Treatment of High-Precision Roller Screws for High-Speed ​​and Heavy-Load Applications

Abstract

This application relates to the field of metal heat treatment steel processing technology, and discloses an optimization method for heat treatment of high-precision roller screws for high-speed and heavy-load requirements. Based on pre-collected geometric models, material properties, cooling medium flow rate and flow field data, and historical quenching test data of the screw, a digital model of quenching heat conduction and heat transfer is established. The simulated cooling curves, vapor film stage duration, and target cooling rate parameters of representative areas on the screw surface are calculated to form a set of quenching control parameters. Real-time closed-loop control and optimization updates are performed by combining the temperature distribution on the screw surface and the local temperature data of the cooling medium. This application can improve the zonal control capability, result consistency, and parameter call reliability of the quenching cooling process.
