Small nails are made by the circular motion of the round wire with the diameter of the nail rod through straightening → punching → wire feeding → clamping → cutting → stamping and other circular motions of the nail making machine. Every step in this process is very important.
The punching movement on the nail making machine is a reciprocating movement of the connecting rod and the punch by the rotary movement of the main shaft (eccentric shaft), thereby implementing the punching movement. The clamping movement is repeated pressure on the clamping rod by the auxiliary shafts (also eccentric shafts) on both sides and the rotation of the cam, causing the clamping rod to swing left and right, clamping and loosening the active nail mold to complete a cycle of wire clamping. motion. When the auxiliary shaft is rotated, the small connecting rods on both sides are rotated to reciprocate the knife and tire case on both sides, and the cutting knife fixed in the knife and tire case realizes the shearing movement. The wire for making nails is plastically deformed or separated by punching of the punch, clamping of the die, and cutting of the cutter to obtain the desired shape of the nail cap, nail tip, and nail size. The quality of the stamped nails is stable, the production efficiency is high, and the operation is convenient. It realizes the automation and mechanization of the nail making machine, which greatly reduces the production cost of the nails. Therefore, the accuracy and structure of the main shaft, the auxiliary shaft, the punch, the mold, and the tool directly affect the forming and accuracy of the nail.
