一、Device description
CNC punching machine is an automatic machine tool equipped with a program control system. The control system is able to logically process and decode programs with control codes or other symbolic instructions to make the press act and machine the part.
二、Features of CNC punching machines
The operation and monitoring of the CNC punching machine are all done in this CNC unit, which is the brain of the CNC punching machine. Compared with ordinary punching machines, CNC punching machines have the following characteristics:
● High processing accuracy, with stable processing quality;
● Large processing area: 1.5m*5m processing format can be completed at one time;
● Multi-coordinate linkage, complex shape parts can be processed and cut and shaped;
● When the machining parts are changed, generally only the CNC program needs to be changed, which can save the production preparation time;
● The punching machine itself has high precision, large rigidity, and can choose a favorable processing amount, with high productivity;
● The degree of automation of the punching machine is high, which can reduce the labor intensity;
● Simple operation, with certain basic computer knowledge training can be used in 2-3 days;
三、System composition
The system consists of two sets of servo drives and servo motors, plus a machine, a computer controller and a traditional punching machine. As shown in the following figure:
四、How the system works
The computer is programmed by software and displayed on a monitor in graphical form. With a few simple operations, a position command pulse is sent to the driver to achieve precise positioning. Cooperate with the stamping speed of the punching machine to complete the processing of various products.
