The spring tube winding equipment has the working principle that: firstly, the two ends of the core rod 900 are arranged on the chucks 11, and the chuck control cylinders 13 control the chucks 11 to move so as to clamp the core rod 900. Then, the feeding mechanism supplies the spring wire to the winding assembly 30 such that the spring wire passes through the support through hole 321 on the support block 32 and the end of the spring wire extends to the other side of the core rod 900, that is, the feeding mechanism is located at the front side of the core rod 900 and the end of the spring wire extends to the rear side of the core rod 900. Here, the spring wire is explained as extending from above the mandrel 900 to the rear side of the mandrel 900. Then, the third front and rear air cylinders 41 of the feeding assembly 40 control the clamping plate 45 to move to the lower part of the end part of the spring wire, and then the up and down air cylinders 43 control the clamping plate 45 to ascend, and the second clamping jaw air cylinders 44 control the clamping plate 45 to act so as to clamp the spring wire. Thereafter, the up-down cylinder 43 controls the clamp plate 45 to descend to avoid the mandrel, and then the rotation cylinder 42 controls the clamp plate 45 to rotate so that the end of the spring wire is directed toward the collet 11 at the loading position, at which time the spring wire at least partially bypasses the mandrel 900. Then, the reset motor 61 controls the slide block 72 to move, so that the slide block 72 drives the feeding mechanism to move, and the end part of the spring wire is inserted into the positioning hole. Then, the second clamping jaw air cylinder 44 controls the clamping plate 45 to release the spring wire, and the feeding assembly 40 completes the feeding action. The third fore-and-aft cylinder 41 controls the movement of the collet 11 away from the mandrel 900 to avoid the loading assembly 40 from affecting the winding of the spring wire. Finally, the first motor 21 controls the chuck 11 to rotate, the chuck 11 drives the core rod 900 to rotate, and the spring wire can be automatically wound on the core rod 900, so that the spring tube is manufactured.
