Each of the small nails is made of a round iron wire with the same diameter as the nail rod through the cyclic movement of the nail making machine such as straightening → stamping → feeding → clamping → shearing → stamping. Every step in this process is very important. The punching motion on the nail making machine is driven by the rotation of the main shaft (eccentric shaft) to drive the connecting rod and the punch to form a reciprocating motion, thereby implementing the punching motion. Clamping motion is (are eccentric shaft) and a minor axis of rotation of the cam on both sides of the clamp rod repeated pressure, the left and right swing clamp rod, embodiments of a mold clamping nail activity, a complete cycle loosen the wire clamp sports. The auxiliary shaft rotates while driving the small connecting rods on both sides to rotate to make the tire cutter boxes on both sides reciprocate, and the cutter fixed in the tire cutter box realizes the shearing movement. The nail-making wire is plastically deformed or separated by punching, clamping of the die, and shearing of the cutter, so as to obtain the required nail cap, nail tip shape and nail size. Nail stamping of stable quality, high efficiency, and easy operation to achieve a nail machine automation, mechanization and greatly reduce the production cost of the nail. Therefore, the accuracy and structure of the main shaft, auxiliary shaft, punch, die, and tool directly affect the forming and accuracy of the nail.
