Reasons for continuous punching of mechanical punching machines

There are various reasons for the continuous punching of mechanical punching machines,mainly including mechanical failures,electrical failures,improper operation,and equipment design defects.The following is a detailed analysis of these reasons:
一、Mechanical malfunction
1.Clutch issue:
The clutch is stuck or loose,and due to uneven wear of the friction plates,the braking is not responsive,resulting in continuous impact.
The material of the clutch spring is poor,and it may become twisted or compressed after long-term use,making it difficult to reset in time and locking the lifted mold,resulting in continuous impact.
2.Brake system wear:

The brake part of the mechanical punch press is severely worn and exceeds the safety range(such as the brake clearance of small punch presses exceeding the range of 0.5mm to 1.5mm),and the brake must be replaced to prevent continuous punching.

二、Electrical malfunction
1.Control valve relay issue:
The relay contacts controlling the air valve stuck,accidentally causing the air valve to become electrified and resulting in continuous flushing.At this point,it is necessary to check and replace the relay.
2.External signal interference:
There are high-power signal interference sources nearby,such as welding machine power supply,plasma equipment,etc.,which may interfere with the normal operation of mechanical punching machines and cause continuous punching.Professional electricians are required to provide signal isolation or shielding measures for the equipment.
3.Equipment static electricity:
The device itself has static electricity,which may also cause continuous charging.An electrician is required to safely ground the equipment or control system and dissipate static electricity.
Second degree protection short circuited or solenoid valve problem:
The second degree drop protection of the mechanical punch press is short circuited,or the double solenoid valve is changed to a single action solenoid valve,which leads to the failure of the protection function and may cause continuous punching.
三、Improper operation
Operators who fail to follow safety operating procedures,such as violating regulations or not using specialized tools,may also result in continuous punching of the punch press.
四、Equipment design defects
Unreasonable mold structure design or defects in the design of the mechanical punching machine itself may also lead to the occurrence of continuous punching phenomenon.
In summary,the reasons for the continuous punching of mechanical punching machines involve multiple aspects such as mechanical,electrical,operational,and equipment design.In order to prevent the occurrence of continuous punching,it is necessary to regularly inspect and maintain the punching equipment to ensure the normal operation of key components such as clutches and brake systems;At the same time,strengthen the safety training of operators and strictly follow the safety operation procedures for operation;In addition,it is necessary to pay attention to the design defects of the equipment and make timely improvements and optimizations.
