Description

Technical Field

[0001] The utility model relates to a bending device, in particular to a bending device for water conservancy and hydropower construction. Background Art

[0002] In water conservancy and hydropower construction projects, pipes will be bent and then laid according to actual use needs. Manual bending has poor quality and low efficiency. The Chinese patent with application number CN202223000014.2 provides a patent for a pipe bending device for water conservancy and hydropower construction. The solution passes the pipe through a clamping seat, positions the pipe through two knobs on the clamping seat, and then drives the support rod to rotate by turning the auxiliary handle, so that the first bending part and the second bending part rotate, and the pipe is bent under the cooperation of the auxiliary bending seat. During use, the two threaded rods are driven to rotate by turning the two knobs, so as to drive the two clamping plates to move up and down, so as to adjust the size of the area enclosed by the two clamping plates and the V-groove to adapt to the bending of pipes of different thicknesses. At the same time, the two arc grooves and the V-groove are opened The size is large and can be used for pipes of different thicknesses; this structure replaces pure manual bending, effectively reduces the labor intensity of operators, and improves the bending quality to a certain extent; but on the one hand, every time the pipes to be bent are of the same diameter or different diameters, it is necessary to manually turn the knob to limit or cancel the limit of the pipe to be bent, which not only increases the workload of the operator, but also reduces the efficiency; on the other hand, the clamping seat of this structure cannot be set too large, because when the clamping seat is too large, when positioning the pipe to be bent with a smaller diameter, the two clamping plates cannot be completely fitted with the pipe to be bent, so that the limiting effect will be reduced; on the other hand, since the auxiliary handle is manually turned for bending, the operator's physical strength will gradually decrease with the increase of working hours, making the bending efficiency lower and lower, so that large-scale bending operations cannot be performed.
