| Number: | Failure phenomenon (by action order) |
Review the method for repair |
| 1 | In automatic mode, press the start button, press welder does not work. | Check and start the hydraulic station, and the operation table, "hydraulic system" indicator light; Check and connect the compressed air supply, to ensure that the compressed air pressure> 0.8Mpa, and the operation stage, "Air System" indicator lights; Check and connect the cooling water, cooling water circulation to ensure normal temperature normal, and the operation stage "cooling system" indicator lights; Check and ensure that the implementing agencies blanking in the initial position of the cylinder, the initial position limit switch connected to the normal; Check and ensure the press in the initial position (the position), the position limit switch connected to the normal; Check and ensure that institutional blanking blanking circuit pneumatic cylinder normal (including valve, cylinder, gas pipeline); Check and ensure that institutional blanking blanking reset the trip switch is connected to the normal axis. |
| 2 | After falling a twist action to stop the steel, blanking the shaft is not reset. | Check and ensure the twisted square steel blanking switch is close to normal; Check and adjust the twisted square steel trough down the gap (by adjusting the copper block is installed), so that clearance for the diameter of twisted square steel. |
| 3 | After falling a twisted square steel, feeding off the hook step to the next stop is not expected location blanking. | Check and ensure that institutional blanking blanking circuit pneumatic cylinder normal (including valve, cylinder, gas pipeline); Check and ensure that institutional blanking blanking reset the trip switch connected to the normal axis; Check and ensure that the feed position limit switch hook connected to the corresponding normal step; |
| 4 | Square root of twisted steel falls after the second operation to stop, blanking the shaft is not reset. |
1, 2 method to check the light sequence. |
| 5 | After blanking movement, feeding them off the hook material, and stop action. | Check and ensure that press in on the location, press the limit switch connected to the normal position; Check and ensure the twisted square steel hand in the lower position of trust, care position limit switch connected to the normal men. |
| 6 | Feed the steel hook will feed two twisted in place, twisted steel care hand side does not rise, and stop action. | Check and ensure the blanking body feed on the trip switch is normally in place; Check and ensure the twisted square steel hand in the lower position of trust, care position limit switch connected to the normal men. |
| 7 | Hand-twisted square steel prop master up, hold up the twisted square steel, but does not retract the feed hook, stop action. | Check and ensure the twisted steel care hand side limit switch connected to the normal position; Check and ensure the press electrode position, adjust the position limit switch position on the press, so care rose hand care and hand on the press stand up mandril, the care and reliable hand position limit switch action. |
| 8 | Twisted square steel hook retraction feeding, but the electrodes do not press down, stop the action. |
Check and ensure that the feed hook retraction in place; Check and ensure that feed back into place the hook switch is connected to the normal schedule. |
| 9 | Press down the electrode in place, but not be welded, and stop action . |
Check and ensure that hands down to the next position of trust; Check and ensure that child care position limit switch connected to the normal men. |
| 10 | A welding operation, but no welding current or welding current exception. | Check and ensure the welding parameters normal; Check and ensure the welding electrode welding surface wear is normal; Check and ensure the welding control circuit is normal; Check and ensure the welding transformer primary voltage SCR working properly; Check and ensure the welding transformer secondary rectifier is working; Check and ensure the welding electrode and the electrode contacts the contact surface between Block and reliable, the electrode plate bolts clamping reliable. |
| 11 | Welding is completed, not to pull the net, the action stops. | Check and ensure the deduction of wood has been relaxed; Check and ensure the press has been on the itinerary; Check and ensure correct beam has been on the trip |
| 13 | Pop size errors. | Check and ensure that netting size setting is normal;Check and ensure the netting agencies working on the rotary encoder (including rotary encoders, rotary encoders couplings, etc.); Check and ensure that the entire rack and pinion rotary encoder meshing well. |
