[0027] In some embodiments, please refer to the drawings in the description Figures 1-4 A spring forming equipment, including spring winding machine 1, one side of spring winding machine 1 is fixedly connected with fixed block 2, still including feeding mechanism 3, feeding mechanism 3 includes four feeding wheels 31 that are rotationally connected to the front end of fixed block 2, one end of feeding wheel 31 is fixedly connected with belt pulley 32, transmission is connected with belt 33 between the surface of two belt pulleys 32, one end of one side belt pulley 32 is fixedly connected with servo motor 34, one side of fixed block 2 is clamped with support block 36, the surface of support block 36 is fixedly connected with limiting cylinder 35, a plurality of ball 37 are rotationally connected to the inner wall of limiting cylinder 35, and the surface one end of limiting cylinder 35 is funnel-shaped.

[0028] Spring winding machine 1 is usually composed of a machine body, a feeding mechanism 3, a winding mechanism, a variable-diameter mechanism, a pitch mechanism, etc.

[0029] Machine body: it is the basic framework of spring winding machine 1, provides installation support and stable working platform for other components.

[0030] Winding mechanism: is the core part of the spring winding machine 1, mainly composed of mandrel, winding cam, cutter and so on. The mandrel is used to support and position the wire, so that it is wound according to the predetermined shape; the winding cam controls the winding angle and the number of turns of the wire; the cutter is used to cut off the wire, completing the production of the spring.

[0031] Variable diameter mechanism: when producing springs with different outer diameters, the variable diameter mechanism can adjust the outer diameter size of the spring. By changing the position or angle of the winding mold, the outer diameter of the spring is changed to meet the needs of different products.

[0032] Pitch mechanism: used to control the pitch of the spring. The pitch mechanism can accurately adjust the pitch size of the spring through mechanical transmission, hydraulic transmission or motor drive, etc., to produce springs with various pitch requirements.

During the winding process, the spring winding machine 1 accurately controls the winding length and pitch of the metal workpiece according to the set number of turns and pitch.

[0035] When winding to the set number of turns, the cutting device of the spring winding machine 1 will automatically cut off the metal workpiece, so that the spring is separated from the raw material.
