Principle Of Synchronous Operation Of NC Feeder And Press Machines

It is an inevitable trend for the industry to develop stamping processing towards high precision, high efficiency and high automation, which puts forward higher demand for the supporting feeder equipment of the punch, and also promotes the continuous updating and upgrading of the punch feeder. From the original air feeder with reliable quality to the second generation of roller feeder, the precision, stability and automation have been significantly improved, However, it still cannot meet the increasingly high demand for precision stamping, and the connection between the holding and feeding actions and the stamping points of the die is not good. The commissioning of the feeder machine is relatively cumbersome, which has become increasingly unable to meet the needs of modern stamping production.

The principle of synchronization between the NC feeder and the punch is not complicated. In simple terms, the PLC of the NC feeder receives the angular shaft angle signal transmitted by the crankshaft encoder of the punch, realizes feeding and relaxation at the specified time sequence through calculation, so as to achieve the purpose of synchronous operation with the punch, ensuring the accuracy of each feeding and the reliability of stamping. The actual installation method of the NC servo feeder to achieve this effect is also very simple, Just connect two groups of cam signals (one is the feeding signal, the other is the relaxation signal) from the punch, and then connect them to the PLC in the NC feeding electrical control box. The PLC precisely controls the feeding action of the servo system, achieving perfect coordination with the press machines
