Working principle of RNT series nut tapping equipment

The stamped blank of the nut is fed to the intermediate hopper and then to the receiving hopper of the nut-cutting machine. From the hopper, the workpiece falls along vertical guides into the thread cutting unit, where the pneumatic pusher presses the nut workpiece against the driven rotating tap, pushing it along the working part of the tap rod, forming an internal thread. Finished nuts are dumped from the tail end of the curved tap into the finished product container.
