A spring machine with a core shaft structure having a thread feeding function
By setting a wire-pushing mechanism in the middle of the spring core shaft and using a synchronizing sleeve and clutch unit to control the wire-feeding wheel group, the problem of asynchronous wire feeding and material movement within the core shaft is solved, achieving synchronization and improved accuracy of wire feeding, reducing defects in wire conveying, and improving processing stability.

Abstract
The application provides a core shaft structure with a wire feeding function on a spring machine, and relates to the technical field of metal processing equipment. The core shaft structure comprises a shaft body and a wire pushing mechanism located at the middle part of the shaft body. The wire pushing mechanism comprises two synchronous sleeves slidably connected to the shaft body through splines, a wire feeding wheel set rotatably connected to the shaft body, and a clutch unit connected between the two synchronous sleeves. The wire feeding wheel set comprises two wire biting wheels rotatably connected to the shaft body. At least one driving wheel is coaxially fixedly arranged on each wire biting wheel. The clutch unit comprises a connecting rod assembly corresponding to the driving wheels. The connecting rod assembly comprises two clutch plates parallel to each other. The two ends of each clutch plate are rotatably connected to the corresponding synchronous sleeve through a short arm. The application has the advantages of shortening the wire feeding path and the like.
