The feed cylinder 73 step is entered.
And (3) switching on the power supply of the cutter 34, and closing a circulation cutting mode switch after the idle running check cutter 34 is in a normal state. First, the pressing cylinder 22 descends to fix the plate on the workbench 1, and the reset cylinder 55 is retracted to the rearmost end. The cutter 34 cuts backward under weight tension. When the photoelectric switch 37 on the cutter 34 senses the signal of the first baffle 38, the photoelectric switch 37 sends out a switch signal, and the time module starts to count. The cutter 34 continues to cut backwards, when the photoelectric switch 37 of the cutter 34 senses the signal of the second baffle 39, the photoelectric switch 37 sends out a switch signal, and the time module stops timing;
