Touch screen press each cylinder of required button control stretch out with the operation retracted, and realize sending by the forward and backward of stepper motor
Material operation；If the contact for detecting control model is in automatic mode, PLC makes control model enter into automatic mold
Formula, and the length for completing to set required sawing material operation；
Step (2), self-feeding：After opening automatic mode, gas control mechanism control single pole double-acting cylinder B is clamped up and down and is pressed from both sides up and down
Tight sawing bar, left and right clamps gas control mechanism control single pole double-acting cylinder A or so and clamps sawing bar, and left and right and presss from both sides up and down
The position of tight bite will lean against the side of sawing point；Stepper motor is rotated forward after bar is transported into the blank length of setting, saw
Cut and clamp the sawing bar that gas control mechanism control single pole double-acting cylinder C clamps sawing；
Step (3), sawing prepare：Single pole double-acting cylinder A, single pole double-acting cylinder B first unclamp sawing bar, stepping before sawing
To extreme position, single pole double-acting cylinder A, single pole double-acting cylinder B clamp sawing bar to motor movement again, and support bar promotes gas
Control mechanism controls single pole double-acting cylinder D promotes support bar, is that the decline sawing of sawing arm is prepared；
Step (4), automatic sawing, cutting：After sawing is ready to complete, SAWING CONTROL gas control mechanism control single pole double-acting cylinder E promotes saw
Control handle is cut, sawing arm begins to decline carries out sawing, after sawing arm drops to extreme position, in touching button/detection switch
Mechanical stroke switch, SAWING CONTROL gas control mechanism control single pole double-acting cylinder E pulls SAWING CONTROL handle, sawing arm to open
Begin to rise, sawing execution unit resets.
