Step a2, the control module collects a start signal of the second speed, that is, a contact signal of the bending blade 15 contacting the sheet material, and starts the first cylinder 11 with the start signal and drives the first supporting plate to rotate 5, so that the first supporting plate 5 rotates along with the sheet material 19 being bent.
And step A3, the second air cylinder 8 drives the second supporting plate 6 to rotate and abut against the plate according to the starting point signal of the second speed acquired by the control assembly.
Step A4, when the bending is finished, the bending knife 15 slowly leaves the plate 19, the plate 19 props against the second supporting plate 6 under the action of gravity and presses the second cylinder to retract 8, and the control assembly drives the first cylinder 11 to retract according to the collected signal of the magnetic switch 16 of the second cylinder 8 and drives the second supporting plate 5 to rotate until the supporting platform is flush. Specifically, set up magnetic switch 16 at second cylinder piston rod 9, when panel bending finishes, bend sword 15 and slowly leave, panel 19 pushes down second backup pad 6 and drives second cylinder 8 withdrawal under the action of gravity, and magnetic switch 16 is triggered, and control assembly starts first cylinder 11 and drives first backup pad 5 and slowly revolve to supporting platform 4 according to magnetic switch 16's signal.
It should be further noted that the second supporting plate 6 and the second cylinder 8 act as springs during the rotation process, and mainly play a role in buffering and keeping contact with the bent plate, so the thrust of the first cylinder 11 is greater than the thrust of the second cylinder 8, in this embodiment, the first cylinder 11 plays a role in main pushing force, and is required to bear the gravity of the plate and the impact of falling back, the first cylinder 11 is a cylinder of D80, and the second cylinder 8 is a cylinder of D16.
Through the control method of this embodiment, can be effectively greater than 400mm to the width, perhaps weight exceeds the bending of 40 kg's massive plate, after plate bending, plate is cushioned and is caught by second backup pad 6 and slowly fall back to supporting platform under the drive of first cylinder 11 by first backup pad 5, whole plate decline process, the noiselessness produces, it is noisy in the workshop to have avoided, it is more secure to make the operation personnel occupational health, also can not cause certain damage to the panel outward appearance simultaneously, also can not injure the operation personnel.
The method for controlling a noise-proof device of a bending machine disclosed in this embodiment has the same technical solutions as those in the third embodiment, please refer to the description of the third embodiment, and will not be described herein again.
