曼哈特（广东）数控机床有限公司针对下动式数控折弯机过热问题可以采取哪些预防措施呢？

The overheating problem of the downward moving CNC bending machine may be caused by various factors, including but not limited to excessive mechanical load, poor lubrication, cooling system failure, etc. To prevent such problems, the following measures can be taken:
1. Regular inspection and maintenance: Regularly inspect and maintain the bending machine, including cleaning, tightening loose parts, replacing worn parts, etc. This can ensure that the machine is in good working condition and reduce overheating caused by friction of mechanical components.
2. Ensure that the lubrication system is functioning properly: The lubrication system is crucial for reducing machine friction and wear. The quality and quantity of lubricating oil should be regularly checked to ensure that the oil level is within the normal range, and deteriorated lubricating oil should be replaced in a timely manner.
3. Load control: Avoid subjecting the bending machine to excessive loads and try to operate within the allowable range of the machine. If it is necessary to handle workpieces that exceed the range, consideration should be given to upgrading the machine or taking other measures.
4. Keep the cooling system running normally: The cooling system of the bending machine is very important for reducing machine temperature. The operation status of the cooling system should be regularly checked, including components such as water pumps, radiators, and water pipes. If any abnormalities are found, they should be dealt with promptly.
5. Use appropriate molds: Choosing the right mold is crucial for reducing machine load and overheating. Suitable molds should be selected based on the material, thickness, and shape of the workpiece to avoid overloading the machine due to the use of unsuitable molds.
6. Training operators: Ensure that operators are familiar with the operation and maintenance knowledge of the bending machine, and can use the machine correctly and in a standardized manner. Avoid overheating issues caused by improper operation.
By taking the above preventive measures, the occurrence of overheating problems in the downward moving CNC bending machine can be effectively reduced, and the service life and work efficiency of the machine can be improved.
