Factors of unstable quality in tube bender

pipe bending machine

In the tube bender processing, the bending is pure, and the pipe bending machine is thinned by the external stress of the outer layer of the inner layer under the action of the external force M. The inner compressive stress acts to thicken, and the combined forces N1 and N2 cause the cross section of the tube to occur. Variety. Based on this factor, the main cause of the deterioration of the bend quality is RX and SX. Therefore, in GBJ235-82, the RX value and the amount of thinning on the outside are clearly defined for various pressure levels. Is to control the value of RX and SX to ensure quality
