Metal tube bending machine in the rapid development of the present, occupies a pivotal space, the public railway construction, boilers, bridges, ships, furniture, decoration and other aspects of the pipeline laying and build, can not be separated from the pipe bending machine. For the structure of the pipe bending machine, the pipe bending machine adopts the touch screen and the numerical control module, the dialog type operation, the program is simple and easy to set up.So what should we do about the folding defects in the inner arc parts of the pipe bending machine? Taiwan and mechanical experts tell you that the elbow bend in the arc part of the phenomenon of the emergence of wrinkles are: the promotion of speed too slow or too fast. In the process of pushing the pipe, the speed of the pipe is too slow to produce the phenomenon of over burning.The fold is produced, and the speed is too fast, and the arc in the curved part can collapse, and the fold of the inner arc part can be generated. Internal and external arc heating temperature is not balanced. Inside and outside arc heating temperature is usually 30-70. When the internal arc temperature is higher than the allowable range, it will be in the inner side of the occurrence of the phenomenon of the occurrence of the phenomenon of fold. Rocker arm resistance is too large. Bending is to rely on the rocker arm to provide bending deformation force, the process of bending the arm must be along with the steel pipe, that is, the length of the elbow and the distance of the rocker arm need to be strictly matched. When the rocker arm running wheel mechanism is not smooth, there will be a lot of running resistance.Or when the floor of the walking wheel will also block the operation of the rocker arm. Because of the great mass of the rocker arm (5-60t), the resistance is enough to cause the bend pipe to collapse when the hot state occurs.So how do we maintain and maintain the pipe bending machine at ordinary times? Taiwan and mechanical experts teach you the following three ways:

1. Cleaning of the oil tank,  clean the pump inlet filter also

2. Equipment began to use after 1 - 2 months, clean the tank and filter hydraulic tank.

3. As found in advance and retreat back cut failure, first check whether the solenoid valve action, such as the solenoid valve is normal, and then check the sequential valve 6X3, relief valve L20H4 - 4HD3 or check valve YF has no impurity card dead phenomenon. (this phenomenon usually occurs when the device starts to use). If the death card, opened with good cleaning with gasoline or diesel, reinstall it.
