Manhart How to determine the malfunction of the punching and shearing machine?

When judging the malfunction of the punching and shearing machine, we need to integrate various information and manifestations to ensure that the problem can be accurately diagnosed. The following are some methods for diagnosing faults in punching and shearing machines, represented and summarized in clear points:
1、 Observing device performance
1. * * Operating Stability * *: Observe whether the punching and shearing machine experiences unstable phenomena such as vibration and increased noise during operation. These phenomena may indicate mechanical component failures or hydraulic system issues in the equipment.
2. * * Cutting accuracy * *: Check whether the material edges cut by the punching and shearing machine are flat and free of burrs. If the cutting accuracy decreases, it may be caused by severe blade wear or mechanical component failure.
2、 Check the power supply and electrical system
1. * * Power status * *: Confirm whether the power supply of the punching and shearing machine is connected properly, whether the plug is plugged in tightly, and whether the power switch is turned on. If the power supply is normal but the device cannot start, it may be an electrical system malfunction.
2. Electrical components: Check if the electrical components of the punching and shearing machine are damaged, such as the motor, control panel, electrical contact points, etc. The damage to these components may cause the equipment to malfunction.
3、 Inspect mechanical components
1. * * Blade Status * *: Observe whether the blade or mold blade of the punching and shearing machine is severely worn or stuck. If the blade becomes dull or stuck, it needs to be replaced or cleaned in a timely manner.
2. * * Transmission device * *: Check if the transmission device of the punching and shearing machine is damaged or loose, such as the transmission belt, gears, etc. Damage or looseness of the transmission device may lead to unstable operation or decreased accuracy of the equipment.
4、 Check the hydraulic system
1. * * Oil level and quality * *: Check whether the oil level and quality of the hydraulic system of the punching and shearing machine are normal. Low oil level or poor oil quality may cause hydraulic pump malfunction or hydraulic oil temperature to be too high.
2. * * Oil leakage phenomenon * *: Pay attention to observe whether there is any oil leakage in the hydraulic system. Oil leakage may cause a decrease in system pressure or equipment damage.
5、 Check the control system
1. * * Control Panel * *: Check if the control panel of the punching and shearing machine can operate normally. If the control panel is unable to operate or displays abnormally, it may be a control system malfunction.
2. * * Signal Circuit * *: Check if the signal circuit of the control system is connected properly and if there is any damage or poor contact. A malfunction in the signal line may cause the equipment to malfunction or fail to respond properly.
6、 Comprehensive judgment
Based on the above inspection and observation results, make a comprehensive judgment. If there is an obvious problem with a component or system, it can be preliminarily determined that the component or system is faulty. If the specific fault point cannot be determined, professional testing equipment and diagnostic techniques can be further utilized for inspection and analysis.
Summary: When judging the malfunction of the punching and shearing machine, we need to conduct comprehensive inspections and observations from multiple aspects such as equipment performance, power and electrical systems, mechanical components, hydraulic systems, and control systems. Through comprehensive judgment and analysis, the cause of the malfunction can be accurately identified and corresponding maintenance measures can be taken. At the same time, regular maintenance and upkeep of the shearing machine is also an important means to reduce the probability of failure.
