The invention discloses a
numerical control cutting machine, which comprises an upper
workbench, a guide post, a guide sleeve, a screw support, a
ball screw, a
numerical control moving head, a connecting seat, a step motor, a rotary die holder, a
servomotor, a
workbench, a balancing connecting rod, a swing plate, a connecting plate, an oil cylinder, and a
numerical control box. The
computer programming control technology and a human-computer interface are adopted by the
machine, a chain wheel on the
servomotor drives a chain wheel on the
ball screw through a chain, so that the connecting seat on the
ball screw drives the numerical control moving head to advance and retreat in the longitudinal direction to realize mobile
cutting; the rotary die holder on the numerical control moving head driven by the step motor can rotate 360 DEG;
layout and blanking are carried out digitally; and the computer controls a hydraulic
system to push the guide post on the oil cylinder to drive a balance mechanism, so that the upper
workbench drives the numerical control moving head ascend and descend to realize automatic
cutting. The
machine has quick response, high precision, stable mechanical properties, low
failure rate, high
automation degree, and high production efficiency without waste and ungraded product, is convenient and safe to operate, and obviously saves energy.
