How to quickly diagnose and solve problems when a rolling machine malfunctions
As an important sheet metal processing equipment, the rolling machine inevitably encounters various malfunctions during operation. In order to quickly diagnose and solve problems, ensure the continuous and stable operation of the production line, we need to start from multiple aspects and take targeted measures. The following are the main steps and methods for quickly diagnosing and solving problems in the event of a rolling machine malfunction:
1、 Power and electrical inspection
Firstly, check the power supply and electrical system of the rolling machine. Ensure that the power connection is normal, the voltage is stable, and there are no short circuits or open circuits. At the same time, check if the electrical components are intact, such as switches, relays, sensors, etc., and if there is any damage or poor contact. If there are any problems, replace or repair them in a timely manner.
2、 Transmission system maintenance
The transmission system is the core component of the plate rolling machine, and its status directly affects the operation effect of the equipment. Therefore, when the rolling machine malfunctions, a detailed inspection of the transmission system should be carried out. Check whether the transmission components such as gears, bearings, and chains are worn or damaged, and whether the lubricating oil is sufficient and clean. If there are any problems, replace the worn parts in a timely manner and supplement or replace the lubricating oil.
3、 Roller shaft and tensioning device
The roller shaft and tensioning device are key components of the plate bending machine for sheet metal bending. Check if the roller shaft is parallel, the surface is smooth, and there is no wear or crack. At the same time, check the working status of the tensioning device to ensure that the sheet maintains appropriate tension during the curling process. If there are any problems, adjust the parallelism of the roller shaft or replace worn parts in a timely manner, and adjust the tension.
4、 Hydraulic system maintenance
For rolling machines equipped with hydraulic systems, the cleanliness and oil level of the hydraulic oil should be checked. If severe hydraulic oil pollution or low oil level is found, hydraulic oil should be replaced or replenished in a timely manner. At the same time, check the working status of components such as hydraulic pumps and valves to ensure their normal operation.
5、 Roller quality and adjustment
The roller is an important component of the plate rolling machine, and its quality directly affects the curling effect of the sheet metal. Check the surface quality of the rollers to ensure they are smooth and free from wear. If the roller is severely worn, it should be replaced in a timely manner. Meanwhile, according to the thickness and material of the board, adjust the gap and pressure between the rollers to ensure the quality of the board’s curling.
6、 Running speed adjustment
The operating speed of the bending machine is also an important factor affecting the bending effect of the sheet metal. Reasonably adjust the operating speed of the rolling machine based on production needs and the characteristics of the board. If the speed is too fast or too slow, it may lead to substandard curling quality of the board.
7、 Fasteners and Lubrication
Check if the fasteners of the rolling machine are loose or missing, and if there are any problems, tighten or replace them in a timely manner. At the same time, regularly lubricate the lubrication components of the equipment to ensure smooth operation and no abnormal noise.
8、 Safety protection and maintenance
In the process of solving the malfunction of the rolling machine, safety should always be the top priority. Ensure that the safety protection devices of the equipment are intact and effective, such as protective covers, safety switches, etc. At the same time, regular maintenance should be carried out on the equipment, including cleaning the surface of the equipment, inspecting electrical circuits, etc., to extend the service life of the equipment.
Through the above steps and methods, we can quickly diagnose and solve the faults of the rolling machine, ensuring the continuous and stable operation of the production line. Meanwhile, strengthening the daily maintenance and upkeep of equipment is also an effective way to prevent malfunctions and improve equipment performance.
