What are the common faults of quality 200T precision press machine
In some production and processing processes, quality 200T precision press machines are common. However, during the production and operation of presses, due to normal wear, use or improper maintenance, various failures will inevitably occur. So, what should I do when the quality 200T precision press machine fails?
1. The temperature rise of the bearing bush is too high: if the temperature rise of the crankshaft bearing bush changes greatly in a short period of time when the quality 200T precision press machine is working normally or even in idle operation, it is necessary to consider whether the bearing bush clearance is too small, and whether impurities or foreign objects enter the bearing bush, Whether the lubrication is poor, whether it is working under overload and overload for a long time.
2. Vibration of the machine body: Excessive vibration of the quality 200T precision press machine body will also bring many problems, resulting in harsh working environment, reduced machine service life, and reduced precision of forgings. In this case, it is necessary to check whether the flywheel is not well balanced and the beating is too large, whether the crankshaft bearing is seriously worn, whether the anchor screws are loose, and whether the pre-tightening force of the tension bolts is sufficient.
3. Continuous punching of the press: the continuous punching of the quality 200T precision press machine is a very serious fault. First of all, it is necessary to eliminate whether there is an error in the control program of the press, check whether the cam switch signal fails, and whether the clutch friction plate has fallen off and the clutch cannot be disengaged. The brake action fails and does not brake, and whether the intake and exhaust of the clutch and brake are smooth.
If the quality 200T precision press machine fails, it needs to be further analyzed according to the content, and the root cause of the problem can finally be found. Only by judging and handling the faults in a timely and accurate manner can the performance of the quality 200T precision press machine be guaranteed, thereby improving the reliability, lifespan and efficiency of the equipment.
