Based on the above-mentioned device, the present invention also proposes a kind of planer blade automatic processing technology, it is characterized in that, comprises the following steps:

1) The raw sheet material is sent to the stamping die 701 on the punching machine 700 to be stamped to form a blade. During the upper and lower process of the upper module, the swing mechanism 103 pushes the push rod 110 to move through the power provided by the punch press 700, so that the sliding seat 104 moves on the guide rod one 105 and lifts the retrieving rod 111 completed by the retrieving rod elevating cylinder 101 from the punching machine. Draw out in the mold 701 to move the trough 112 to the bottom of the reclaiming cylinder 106;

2) The retrieving cylinder 106 drives the suction block 109 to move downward to suck the blade in the trough 112, and then the retrieving rod 111 continues to move backward. At this time, the suction block 109 quickly descends under the drive of the reclaiming cylinder 106 to remove the blade. Put it into the blade clamping groove 902, then the suction block 109 returns to its original position, and the take-up rod 111 returns to the stamping die 701 to receive the material again under the cyclic movement of the swing mechanism 103;

3) The blade is sent into the station of the automatic discharge pendulum mechanism 600 by the conveyor belt 904 in the blade clamping groove 902: the suction plate 607 on the main rail frame 615 is driven down by the main lifting cylinder 2 604 to make the suction plate 607 Adhere to the positioning rubber sheet 903 and block the blade clamping groove 902, then the second lifting cylinder drives the lifting magnet bar 606 on the positioning block 605 to descend and insert into the positioning hole 601, so that the positioning hole 601 part on the suction plate 607 With magnetism, the blades in the blade clamping groove 902 are neatly absorbed and stared at the suction plate 607 at this time;

4) After the suction plate 607 is finished absorbing the material, the main lift cylinder 2 604 drives the main rail frame 615 to move upward as a whole, and then pushes the cylinder 602 to push the moving frame 2 603 to move forward as a whole so that the suction plate 607 enters the workbench 1 10 On the magnetic conveying material assembly line 50, the magnet rod 606 on the positioning block 605 driven by the secondary lifting cylinder 2 rises and leaves the positioning hole 601, and at this moment, the blade of the suction plate 607 becomes and stays on the magnetic conveying material assembly line 50;

On both sides, the cylinder 5 405 drives the clamping shaping plate 409 to descend to pressurize both sides of the blade, and the stamping rebound and the blade that has not been punched in place are shaped. After the set time is reached, the clamping shaping plate 409 is pressed by the cylinder 5 405 drives up and moves on;

7) The color mark sensor 60 starts to detect the blade after shaping, if it is found that there are rusty spots on the blade, it will feed back to the defective product rejecting mechanism 300 mechanism through the circuit signal line;

8) After the blade enters the station of the defective product rejecting mechanism 300, the defective product rejecting mechanism 300 uses the cylinder 7 305 to drive the displacement of the main rail frame 7 307 through the detection result of the color mark sensor 60, so that the magnet rod 7 302 reaches the top of the unqualified blade Driven by the lifting cylinder seven 310, the magnet bar seven 302 descends into the positioning hole seven, so that the positioning hole seven has magnetism, and other positions have no magnetism, and unqualified blades are sucked into the defective product recovery box 311, and the remaining The blade continues to advance and is discharged through the discharge mechanism slideway 202, and the processing ends.
