[0002] The spring coiling machine is a highly automated device used to produce springs, which can realize automatic wire input, curling and spring cutting. At present, the spring coiling machine knife group on the market has a working process as follows: the spring coiling machine is running, and the spring wire is fed into the forming knife group by the feeding guide plate. Then, under the action of the guide rod, it is gradually wound around the mandrel to form. The push rod contacts the spiral coil and pushes it outward a specified distance. Repeat the above operation until the preset length of the spring is reached. The cutter moves down to cut the spring wire and complete the processing of a spring. The above equipment can complete the processing and production of springs, but it can only process springs of conventional diameters or circular diameters. When the user wants to produce vortex springs, the spring will interfere with the feeding guide plate and will not match.
