The stop block 83 is used to guide the fed spring material so that the material is coaxial with the feeding hole 82 when it is fed out.

[0046] Multiple guide components 3 are evenly spaced, and two opposing guide components 3 form a group. A curling component 4, a positioning component 5, and a cutting component 6 are respectively mounted on the slide 32 of each group of two opposing guide components 3. Figure 2As shown, the curling assembly 4 is in a vertical relative state, the positioning assembly 5 and the cutting assembly 6 are both in an inclined state, the folding assembly 7 is installed on one of the horizontal guide assemblies 3, and the guide assembly 3, the curling assembly 4, the positioning assembly 5, the cutting assembly 6 and the folding assembly 7 are all arranged around the feeding assembly 8.

The other end of the push rod 24 extends above the corresponding guide rail 31 and is in contact with one end of the corresponding slide 32. When the push rod 24 rotates, its other end pushes the slide 32 to slide on the guide rail 31. Conversely, when the protruding part of the cam 22 moves away from the push rod 24... The pneumatic spring rod 33 pulls the slide block 32 back in the opposite direction. At this time, the two positioning components 5 approach each other to clamp the spring sheet material.
