AI Technical Summary

Technical Problem

In the existing spring manufacturing process, the lack of a coordinated mechanism between horizontal machining and single heat treatment makes it difficult to improve the consistency of spring quality, individual differences cannot be captured and compensated in real time, heat treatment cannot achieve differentiated control, and the system cannot learn and adapt to dynamic changes, resulting in a decline in performance inconsistency.

Method used

A disturbance feature online encoding module is used to collect spring processing disturbance data in real time. A personalized heat treatment command is generated through an online control law dynamic calibration module. Non-uniform heat treatment is performed using a personalized heat treatment execution module. An adaptive closed loop is established through a quality feedback and model self-optimization module to optimize the control model.

Benefits of technology

It achieves precise control over individual spring variations, improves product consistency and pass rate, enhances system adaptability and long-term stability, and reduces human intervention.

Abstract

The invention relates to the field of spring manufacturing intelligent control, and discloses a spring horizontal processing and single heat treatment coordinated intelligent regulation and control system which comprises the following steps: a disturbance characteristic on-line coding module which is used for collecting and coding physical disturbance generated by each spring in rolling, welding and other horizontal processing procedures in an on-line manner, the disturbance characteristic spectrogram generating module is used for generating a unique disturbance characteristic spectrogram, and the online control law dynamic calibration module is used for receiving the disturbance characteristic spectrogram and reversely solving a compensatory personalized heat treatment instruction sequence for the spring; the personalized heat treatment execution module is used for executing accurate single heat treatment on the single spring according to the instruction sequence; and the quality feedback and model self-optimization module optimizes the control model for a long period according to the final actual measurement performance of the spring. According to the method, a direct mapping and feedback optimization closed loop from horizontal machining disturbance to single heat treatment control is constructed, deep cooperation of the two is achieved, process fluctuation is effectively compensated, and the consistency of spring product quality is remarkably improved.
