Dear all
As I said we are doing a metal sheet cutting machine with Rotart shear which as to cut800mm to 5000 mm
The main problem what we are facing is we are not able to achieve the maximum speed of the machine as the motor is selected by the customer. he selected the motor for 80 cuts/min when it is 800mm, but we are able to achieve only 50 cuts. and our cutting profile is like blade will be on the top and when it reached the material it will come down with synchronous speed and cut it when we are increasing the speed we are getting over voltage trip on the drive.
according to customer this profile is not good and he wants the rotary to move always and accel the speed when it going to cut. looking o this I looking for all your suggestion. which profile will be good customers or ours. Will the shear has to move always or it can stop on the top. right now our accel time and decel time is very less. shear is 340mm and we are having leveler and uncoiler..
What should I have to do. Syn angle is 40 as calculated by customer. Speed of the leveler and shear should be same when it is cutting for synchronization.
Looking forward for your suggestions
With thanks and regards
