In the application of spring machine every time when it first started to return to zero operation, in order to find the correct starting position. The implementation of this function is the use of a column is arranged on the motor side shaped induction switch, through a screw internal to trigger it. Zero is correct operation is running in a circle will only trigger an induction switch, the induction switch is triggered when the shine; when the correct zero after the end, the machine will stop at the origin position, the induction switch. Induction switch and the nut at the distance of 2mm is good, is easy to hit too close, too far will not feel signal.
  Summarizes the causes of a cam spring machine axis is not normal zero:
  1, the induction switch is arranged too close, leading to the switch has been lit;
  2, the induction switch is arranged too far, not to signal induction;
  3, the induction switch failure, often bright or not bright.
  The occurrence of the above situation, the solution:
  1, reinstall the induction switch, method is that the cam shaft to rotate to screw the high, then the induction switch load, met screw bit after the switch back 2 wire mouth.
  2, if the judgment switch is broken, replace the induction switch.
  Computer spring machine is mainly controlled by AC servo, spring machine computer as a controller control system, various manufacturers on the market, is all through the speed control and position control in two ways to realize the control of A. About the system out of control, is also adjustable machine master often said that the "speed" defects, cut the PC system in place (computer numerical control spring machine controller) is not free to appear, the PC then in speed control in a casual, defect is more difficult to eliminate.
  Inductive control fault causes CNC spring machine system:
  1, power supply problems, such as a power outage or poor contact;
  2, the servo motor encoder and echo circuit problem;
  3, spring processing program to write the problem;
  4, AC servo control board circuit;
  5, all kinds of control line connector, terminal problems.
  On the safety valve computer spring machine failure, how to eliminate?
  1, the safety valve cannot be opened normally;
  2, the valve can not be opened according to routine;
  3, safety valve leakage, no stretch or sealing surface loose.
  When the occurrence of the phenomenon, summarizes its processing method:
  1, adjust or replace the spring, blowing dirt, such as leakage of grinding or replacement parts (according to the technical requirements for calibration, easy to use).
  2, check the calibration and dismantling the calibration, in accordance with the relevant instructions to troubleshooting.
