Second step is for adjusting the position of material: 4. when the second sensor (7) detects billot (10), adjust motor (4-4) and drive positioning plate (4-1) and adjust the position of billot (10) forward by predeterminable range, simultaneously y-axis motor (2-6) driving mechanical hand (3) mobile one section default distance forward; 5. when adjusting motor (4-4) work, flexible cylinder (3-1) work on mechanical arm (2-1) both sides is protracted, and the material folding plate (3-3) that drives open mode is mobile forward; 6. after finishing predeterminable range, y-axis motor (2-6) stops, when adjusting motor (4-4) when also finishing predeterminable range, billot (10) is in the position between positioning plate (4-1) and the position-limited lever (3-4), front and back position is adjusted operation and is finished, and billot (10) is in the clamp area of material folding plate (3-3), and then both sides material folding cylinder (3-2) is worked simultaneously and clamped billot (10); 7. then X-axis motor (2-4) work, X-axis slide block (2-2) by X-axis slide rail (2-3) driving mechanical hand (3) so that billot (10) toward moving to right, stop when arriving the initial workpiece Working position of presetting;
The 3rd step was stamping-out and feeding operation: 8. after finished the adjustment position, the order slider of punch started, and made its tenesmus finish initial workpiece processing; 9. the 3rd sensor (8) is installed to detect the slider of punch operation that whether drops at punch press, when slider of punch is processed first, the 3rd sensor (8) detects its operation, and preset step distance drive billot (10) by system according to this signal command X-axis motor (2-4) basis and carry out step feeding, and a signal is once given in every processing, beginning stepping processing;
The 4th step was avoided punching machine mold for the material folding hand: 10. when stepping made four-sensor (9) detect right manipulator (3), right material folding plate (3-3) unclamped material, and right flexible cylinder (3-1) the right material folding plate of drive (3-3) is retracted simultaneously; 11. when stepping made four-sensor (9) detect right manipulator (3), right telescopic cylinder (3-1) protracted, right material folding plate (3-3) recovers material folding; 12. when stepping made four-sensor (9) detect left manipulator (3), left material folding plate (3-3) unclamped, left telescopic cylinder (3-1) drives left material folding plate (3-3) retraction simultaneously; 13. when stepping made four-sensor (9) detect left manipulator (3), left telescopic cylinder (3-1) protracted, left material folding plate (3-3) recovers material folding;
The 5th step finished single processing and enters a new line afterwards: 14. when punching out machines default single operation quantity, suspends pressing operation, allows adjustment motor (4-4) drive positioning plate (4-1) and resets; 15. by X-axis motor (2-4) and y-axis motor (2-6) work, make material mobile according to parameter preset again, enter the initial workpiece job position of the second row; 16. the startup slider of punch, after first punching out finishing the second row, it is oppositely mobile that X-axis motor (2-4) drives material, begins the second row stepping operation; 17, finish the second row operation after, continue line feed and left and right sides reciprocating working;
The 6th step resetted and discharging after finishing this job task: 18. behind last part of extremely default last row of row of operation, and slider of punch stops; Y-axis motor (2-6) driving mechanical hand (3) begins to be reset to initial position; Simultaneously X-axis motor (2-4) continuous working drives billot (10) and continues to turn right away; 19. when expecting that when reaching discharge position, X-axis motor (2-4) stops; This moment billot (10) broken away from the punch press lathe bed, and be in unload charging basket directly over; 20. then, both sides material folding plate (3-3) unclamps billot (10) simultaneously, the flexible cylinder (3-1) on both sides drives material folding plate (3-3) Rapid reset simultaneously; Because the position of two position-limited levers (3-4) does not change, when material folding plate (3-3) when fast pumpback puts in place, billot (10) is in vacant state, can only fall into charge basket under it in the mode of free-falling body, thereby realize automatic discharging; 21. after the discharging, X-axis motor (2-4) drive y-axis motor (2-6) is turned left and is resetted, and finishes the cycle operation that enters next time feeding after resetting;
The 7th step cycle operation: 22. work as a upper billot (10) fulfils assignment, and when X-axis motor (2-4) drove y-axis motor (2-6) arrival rightmost discharge position, system began upper next billot (10), makes system enter next work cycle; 23. after y-axis motor (2-6) put in place again, detecting to be in such as sensor had the material state, then y-axis motor (2-6) again driving mechanical hand (3) start working and namely begin circulation, if without material then stop.
