Applications of AC80C-Y Punch Press Special Inverter

Abstract: Veichi AC80C-Y Punch press is a stamping type press. In general, the stamping process is energy-saving and efficient compared with traditional mechanical processing, and the stamping process has less demanding of operating technique and a variety of mold machining products can be made, which is why Veichi AC80C-Y Punch Press Special Inverter is widely used. There is a steady increase in drive speed when punch press has started with no mechanical impact, which protects the mechanical part and extends maintenance time. The speed of Veichi AC80C-Y punch press inverter can be adjusted according to product requirements to ensure product quality and reduce scraps.

1. Working Principle of Punch Press

Punch is mainly used for sheet metal forming. Punching, forming, stretching, trimming, fine blanking, riveting and extrusion can be made by the mold, which are widely used in electronics, telecommunications, home appliances, vehicles and so on.

The principle of the punching machine is to convert circular motion into linear motion. The main motor drives the flywheel and the gear, crankshaft (or eccentric gear), connecting rod are driven through the control of the clutch to achieve linear motion of the mold.

Note:

(1) When installing a DC reactor, be sure to remove the jumper between P1 and (+) terminal;

(2) Multi-function input terminals (X1 ~ X7 / PUL) can select NPN or PNP transistor as an input signal, and the bias voltage can be the inverter internal power supply(+ 24V terminal) or an external power supply (PLC terminal). The illustrated switch pulling to +24 indicates "+ 24V" and "PLC" is in short-circuited state.

(3) Analog monitor outputs are the special output for frequency meter, ammeter, voltmeter and other special meters, and the analog monitor output cannot be used in control type operation such as feedback control.

(4) Due to the presence of various types of pulses, the specific wiring methods please see in detailed description.
