Abstract
The invention discloses an automatic reversing control method for wire feeding of a linear cutting machine. The method comprises the steps of (1) driving a wire feeding barrel to a reversing position at one end through a motor; (2) recording the starting position through a wire feeding controller; (3) driving a wire feeding barrel to run through the motor, and performing linear cutting processing for a workpiece through an electrode wire on the wire feeding barrel; (4) coding and counting the number of rotating cycles of the wire feeding barrel through the wire feeding controller according to a pulse signal fed back by a coder on the wire feeding barrel; (5) stopping the motor when the wire feeding barrel runs to the reversing position at the other end, recording the data of the number of the rotating cycles at the end through the wire feeding controller, and driving the motor to reverse and rotate through the wire feeding controller so as to perform the reversed linear cutting processing through the wire feeding barrel; (6) driving the motor by the wire feeding controller to automatically reverse by a reciprocating manner according to the stored data of the number of the rotating cycles. With the adoption of the method, the running safety and stability of the linear cutting machine can be effectively improved, and the machine can be prevented from being damaged due to small service life and large impact force of a mechanical switch.
