Several common troubles and treatment methods of forging press

In the production of forging press, due to routine wear, maintenance or improper use, it is possible to cause all kinds of faults. Such as:
One, airframe vibration: airframe violent vibration will bring a lot of problems, may cause bad working environment, forging press service life shortened, reduce the accuracy of forgings and so on. For this case, the initial judgment of the balance of the flywheel is not good, too much jump, crankshaft bearings are seriously worn, whether the loosening of the anchor screws, tension bolts pretension is sufficient.
Two, Lian Chong: forging press continuous punching is a very serious fault, light will cause forgings, waste, mold damage, heavy equipment damage. In this regard, we should exclude the forging press control program is error, cam switch signal inspection is not a failure, whether the loss caused by the clutch friction plate clutch can not be disengaged, brake failure action not brake, clutch, brake exhaust is smooth.
Three, stuffy car and overload: in normal work, the clutch slip will cause stuffy car. After the occurrence of the stuffy vehicle, we must first determine what happened in the stuffy car position, and then adopt corresponding measures, generally can be adjusted by increasing the mold closing height to solve; intake pressure can also increase the clutch, the lower dead point before and after the stuffy car were resolved through the open anti car or open car. The selection of equipment is unreasonable, the forging temperature is too low, the die is adjusted improperly, repeated replacement of the forgings or rigid foreign bodies on the die may lead to overload of the forging press. The forging press is a heavy accident, and it is very difficult to handle. When the existing methods are not free, only the cutting nut or the loosening nut of the body is removed.
