Why does the spindle of the bending machine bounce radially? | top selling wire bending machine
Plates can actually be bent, but because of the hardness of the plates, special bending equipment is needed to bend the plates. The bending machine has good accuracy, so what is the reason for the radial runout of the spindle?
1. The influence of the use of sliding bearings on the pure radial runout of the spindle. When the press brake is supported by sliding bearings, the main shaft rotates in the bearing hole with its journal. For lathe-type plate rolling machines, during the machining process, the direction of force of the spindle is the same, and the spindle journal is pressed against the fixed place on the surface of the bearing hole by the cutting force. At this time, different parts of the main shaft journal are in contact with a fixed part in the bearing hole. The roundness error of the journal of the bending machine will cause pure radial runout of the main shaft rotation, and the shape error of the bearing hole affects the rotation accuracy of the main shaft. The impact is small. The cutting force acting on the spindle rotates with the rotation of the boring tool. A certain fixed part on the journal is in contact with different parts of the bearing hole surface. Therefore, the roundness error of the bearing hole will cause the pure radial of the boring machine spindle Runout, and the shape error of the spindle journal of the boring machine has little effect on the rotation accuracy of the spindle.
2. The influence of rolling bearings on the pure radial runout of the spindle. When the main shaft of the bending machine is supported by rolling bearings, the factors that cause pure radial runout of the main shaft are not only the accuracy of the bearing itself, but also the accuracy of the matching parts of the bearing of the equipment.
These reasons will cause the main shaft of the bending machine to jump radially, and some bad operations should be corrected in time when using it. During our use, we should pay attention to the influence that some factors may have on the equipment.
