Specifications of nuts tapping equipment series RNT

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.

PNEUMATIC FOUR-SPINDLE THREAD-ROLLING MACHINE FOR NUTS

Equipment for thread cutting /rolling for standard, flange, round nuts. This nuts tapping machine is designed for cutting hexagon, four-sided, nylon and flange nuts. Thread-rolling machine pitch fully complies with the requirements for the processing of nuts in different shapes, lengths and hardness. Convenient location of the control panel, easy operation. Each axis can be operated independently. Using the control panel, you can freely choose the left or right cutter, adjust the length of cut, adjust the speed of rotation of the tool axis. The process of cutting is controlled by a programmable logic controller (PLC).

The machine has the following components: an independent counter, independent control of the automatic thread cutter with circulation, management of supply, monitoring and control system, alarm system. Checking the current sensor to automatically control the process of cutting and the nut jam when applying that helps avoid breaking the mold. Tool exchange is simple and fast. A system of filtering the iron residues. The machine got CE certificate and fully complies with the EU's health and safety standards.
