Manhart How to evaluate the effectiveness of maintenance and cleaning of the bending machine?

**Evaluation of the Effectiveness of Bending Machine Maintenance and Cleaning**
1、 Introduction
Regular maintenance and cleaning of the bending machine is an important measure to ensure efficient and stable operation of the equipment. To measure the effectiveness of these efforts, a series of evaluations are needed. This article will evaluate the maintenance and cleaning effectiveness of the bending machine from the aspects of machine surface cleanliness, lubrication effect, fastening condition, electrical system status, cutting tools, hydraulic system, vibration and noise, and protective work.
2、 Assessment content
1. Machine surface cleanliness
-Assess whether the outer surface of the bending machine is clean, free of oil stains, dust, and other debris.
-Check if the ventilation openings and heat sinks of the lubrication system and electrical cabinet are clean and unobstructed.
2. Lubrication effect
-Check whether the lubrication system is working properly, whether the lubricating oil or grease is sufficient and clean.
-Check the viscosity and color of the lubricating oil to assess its degree of aging.
-Monitor whether the device emits abnormal friction sounds during operation to evaluate the lubrication effect.
3. Tightening situation
-Check all fasteners of the bending machine for firmness, reliability, and no looseness.
-Tighten and inspect components with abnormal vibrations to ensure stable operation of the equipment.
4. Electrical system status
-Check if the electrical circuits, wiring terminals, and switches are securely connected and undamaged.
-Evaluate the working status of electrical components, such as motors, controllers, sensors, etc., to ensure they are functioning properly.
-Check the heat dissipation of the electrical cabinet to avoid equipment failure caused by overheating.
5. Cutting tools
-Check the wear of the cutting tool and assess whether it needs to be replaced or ground.
-Check if the installation of the cutting tool is secure and there is no looseness.
-Check the fit between the cutting tool and the mold to ensure their accuracy and stability.
6. Hydraulic system
-Check the oil level and quality of the hydraulic system to ensure the cleanliness and adequacy of the hydraulic oil.
-Check the pipelines and joints of the hydraulic system to ensure that there are no leaks or blockages.
-Monitor whether the hydraulic system emits abnormal noise during operation to evaluate its performance.
7. Vibration and Noise
-Evaluate the vibration of the bending machine during operation and check if it exceeds the vibration standards specified by the equipment.
-Monitor the noise level of the device during operation to ensure it is within a reasonable range.
-Further inspection and maintenance of components with abnormal vibration and noise.
8. Protection work
-Check whether the safety protection devices of the equipment (such as protective covers, emergency stop buttons, etc.) are intact and effective.
-Assess whether the operators strictly comply with safety operating procedures and wear protective equipment.
-Check whether the environment around the equipment is clean and orderly, and avoid debris affecting the normal operation of the equipment.
3、 Evaluation method
1. Visual inspection: Evaluate the cleanliness and condition of equipment surfaces, electrical cabinets, lubrication systems, hydraulic systems, and other parts by observing them.
2. Auditory examination: Evaluate the vibration, noise level, and lubrication effect of the device by monitoring its sound during operation.
3. Tactile inspection: Evaluate the tightness and leakage of the device by touching its fasteners, pipelines, and joints.
4. Instrument testing: Use professional instruments to test electrical systems, hydraulic systems, etc. to obtain more accurate evaluation results.
4、 Summary
By evaluating the maintenance and cleaning effectiveness of the bending machine, problems and hidden dangers of the equipment can be identified in a timely manner, providing a basis for subsequent maintenance and improvement. At the same time, the evaluation results can also serve as one of the evaluation criteria for equipment performance and quality, providing strong support for the production and operation of enterprises. Therefore, enterprises should attach importance to the maintenance and cleaning of bending machines, and conduct regular effectiveness evaluations.
