When selecting roll forming equipment, we must first pay attention to the diameters of the three top rolls: it must be consistent with the type of steel that has been pre-cold-bent. The top roll has a small diameter, and because of the small contact surface, it is easy to slip during processing; Non-standard steel is easy to deform when in use. The second is about the diameter and stroke of the hydraulic cylinder of the roll forming equipment: the diameter and stroke are based on the output pressure of the hydraulic cylinder and the radius of the processed steel.
The thickness of the steel plate of the roll forming equipment itself and the quality of the skeleton are also very important, requiring the size of the load it can bear and the strength of the equipment itself. There is also the power of the motor and the quality of the reducer, which must meet the corresponding requirements.
The hydraulic oil of the same brand as that used in the system should be used in the operation of the roll forming equipment. The oil temperature should be between 45 and 80 °C, and the impurities in the system should be taken away as much as possible with a large flow rate. The hydraulic system should be cleaned more than three times. After the Ganzhou roll forming machine is cleaned each time, release all the oil from the system while it is hot.
Clean the filter after cleaning, replace the new filter element and add new oil. Select the driving method suitable for the oil pump of the roll forming equipment from the driving methods such as electric, pneumatic, gasoline engine, etc., and understand its capacity; according to the working environment, the working temperature of the oil pump of the roll forming equipment, and the cooling conditions of the roll forming machine can be used to see whether it is necessary to adopt explosion-proof Method.
