Why does a bar break occur in a bar splitting machine?
Bending caused by uneven tension: the same tension is applied to the entire width of the steel plate when the volume is closed. Bending occurs if tension is concentrated on one side
The bending caused by the rapid movement of the correcting device: if the movement of the rectification is too fast during the process, the side of the contact with the rectification will be partially extended and bent.
The uneven gap between the upper and lower blade produces bending: when the left and right gap is larger, the part of the impression is larger than the left and right side of the gap, so it shows a great curvature
As a result of burr and bending: vertical cut due to the blade gap adjustment is not correct, so that the burr larger, when the volume of the edge due to burr, equivalent to the larger thickness of the plate, resulting in edge stretching and bending.
Raw materials: steel plate bending stress in the rolling process is not completely eliminated, longitudinal shear stress release show bending stress, when the middle plate on both sides to release to the outside when slab bending; when the plate on both sides to the Middle stress release appears to the middle curved slab
