Embodiment Construction
[0040] Please refer to figure 2 , when the coiled wire used in the present invention is cut, shaped, preformed, formed, and punched, there are operations such as automatic feeding and automatic pinching. Before explaining the manufacturing process of the present invention, the automatic feeding and automatic pinching devices Wait for an explanation of the operation.
[0041] A. Automatic feeding:
[0042] The automatic feeding device of cold heading machine mainly includes: cam, feeding rocker, ratchet, pawl and feeding wheel and other components. The cam drives the feed rocker to make the ratchet actuate the ratchet to rotate an angle θ. When the ratchet rotates θ, the feeding wheel will synchronously rotate the angle θ to feed the material, then the feeding wheel will be divided into 2π / θ equal parts to feed the material. The effective working outer diameter of the wheel is D, and the feeding length each time is πD÷(2π / θ)=Dθ / 2.
