sheet metal punch press machine

Due to the characteristics of high speed and high pressure of the punch press machines, the use of punch press machines for punching and forming must comply with certain safety regulations. the punch press machine operator must be trained and familiar with operating procedures.

1. Use the safety protection and control device of the punch press machines correctly and do not disassemble it.

2. Before starting up the punch press machine check whether the main fastening screws are loose, whether the dies are cracked, whether the operating mechanism, automatic stop device, clutch and brake works well, whether the lubrication system is blocked or lacks lubrication oil.

3. When installing the dies to the punch press machine, the slider must be lowered to the bottom dead center, the shut height must be correct, and the eccentric load must be avoided as much as possible; the dies must be fastened firmly and checked by pressure test.

4. It is strictly forbidden to use hands to put the work piece on the lower die. Small work pieces must be placed and taken with special tools (tweezers or feeding mechanism).

5. If it is found that the punch press machine is running abnormally or there is abnormal sound (such as batter sound), the feeding should be stopped immediately and check the punch press machine to eliminate the problem.

6. After starting the mechanical punch press machine, the operator should stand up properly, keep hands and head at a certain distance from the mechanical punch press machine. And always pay attention to the movement of the slider. the operator of the mechanical punch press machine must not be distracted in the operation of the mechanical punch press machine.

The reasons for vibration in a mechanical punch press and their corresponding solutions are as follows:
1, Imbalance: Imbalance of components such as the flywheel or crankshaft can cause vibration during operation. The solution is to adjust or rebalance the relevant punch press machine parts.

2, Misalignment: Improper alignment of parts such as the die, punch, or guide rod can lead to vibration. The solution is to ensure proper alignment of these components and tighten them securely.

3, Wear or damage: Excessive wear or damage to punch press machine parts like bearings, gears, or belts can result in vibration as they may not function properly. The solution is to regularly inspect and replace worn or faulty parts.

4, Insufficient machine rigidity: Inadequate rigidity of the machine can cause vibration. The solution may involve increasing the machine's rigidity through reinforcing the structure or using a more stable base.

5, Excessive punching load: If the workpiece is too large or the impact load applied during the punching process is too high, it can lead to vibration. The solution is to adjust the working parameters of the punch press appropriately to operate within the recommended load range.

6, Cooling system issues: Malfunctioning or insufficient cooling systems can result in increased temperature, leading to vibration. The solution is to ensure the cooling system is operating properly and perform maintenance and cleaning as required.

7, Control system issues: Faulty control systems or improper operation by untrained personnel can cause vibration. The solution is to ensure the control system is functioning correctly and provide training to operators on proper operation.

To address vibration issues in a sheet metal punch press machine, implement the aforementioned solutions based on the specific situation. Additionally, regular maintenance and inspections should be conducted to ensure the stability and proper functioning of the punch press.
