[0002] Compression spring machines generally refer to mechanical equipment for producing compression springs. They are developed into automatic and CNC types. According to their functional characteristics, they are divided into: compression spring machines, tension spring machines, computer spring machines, disc machines and special spring machines such as: snake spring machines, torsion spring machines; according to the driving mode, they are divided into: semi-automatic, automatic, CNC and fully computer-controlled.

[0003] In the prior art, the traditional feeding device of the compression spring machine only uses a conveyor belt or a conveyor roller structure to feed the raw materials. At the same time, the spring steel wire needs to be fixed after feeding to ensure the stability of the subsequent conveying of the spring raw materials. However, some existing feeding devices for compression spring machines cannot fix the coiled spring steel wires of different widths, which may cause shaking during the conveying of the spring raw materials, and the scope of application is relatively small. In view of this, we propose a feeding device for a compression spring machine to solve the above problems. Utility Model Content

[0031] Working principle:

[0032] When the feeding device for the compression spring machine is in use, the staff will put the rolled spring steel wire on the outer surface of the mounting rod 2. At this time, the spring steel wire will contact the two limit plates 11 away from the side of the mounting frame 1. At this time, the two limit plates 11 will rotate, and the rotation of the two limit plates 11 will drive the rotation of the connecting block 9, and the rotation of the connecting block 9 will drive the rotation of the first rotating rod 8. The rotation of the first rotating rod 8 will stretch the torsion spring 10. When the spring steel wire is no longer in contact with the limit plates 11, the limit plates 11 will be reset by relying on the elastic force of the torsion spring 10 itself, so that the spring steel wire is located between the two limit plates 11. Subsequently, the staff will rotate the bidirectional threaded rod 5, and the rotation of the bidirectional threaded rod 5 will drive the movement of the two sliding plates 6, and the movement of the two sliding plates 6 will drive the four limit plates 11 to move toward the middle, thereby finally fixing the spring steel wire.
