The roller shaft is one of the important components of the coiling machine. The strength and rigidity of the roller play a decisive role in the forming of the sheet. Common shape defects such as waist drum shape, waist shape, etc. depend on the rigidity of the roller shaft of the coiler, and the fracture of the roller shaft depends on the strength of the roller.
The breakage of the roller shaft can be divided into the early, middle and late stages according to the time. Generally, if the strength and the process specification are scientific and reasonable, the operation is not carried out according to the process flow, or there is no practical experience.
In order to improve the quality of the bending machine and the service life of the machine, in the technical level, the hardness of the working roller shaft of the coiling machine should be increased as much as possible, the wear resistance and fatigue resistance of the roller should be improved, and the contact stress should also be reduced. The quality of life expectancy will increase. The fracture of the roller is complementary to the design, manufacture, coiling process and operation experience. Every link can not be neglected. Only by combining these factors scientifically and organically can we ensure the normal operation of the coiling machine and extend the bending machine. Service life.
