Abstract

This application discloses a method and apparatus for shaping multi-strand wire springs, relating to the field of spring processing technology. The multi-strand wire spring shaping apparatus includes a support frame and multiple furnace bodies, each furnace body providing a heating zone, and each heating zone being equipped with a temperature sensor for acquiring temperature detection data. The support frame is movably installed between the multiple heating zones. The multi-strand wire spring shaping method includes the following steps: in response to a spring shaping processing command, acquiring historical heating data of multiple heating zones; acquiring temperature detection data of multiple heating zones; determining the actual heating power and actual heating time period of each heating zone based on the historical heating data and temperature detection data; and controlling the operation of each heating zone according to the actual heating time period and actual heating power. This method addresses the technical problem of achieving synchronous and uniform heating of multi-strand wire springs using multiple furnace bodies.
