Abstract

The invention relates to on-line monitoring equipment and a method of pipes, in particular to on-line monitoring equipment and a method of PVC (polyvinyl chloride) pipes with unqualified bending. The equipment comprises a roll-over stand, a roll-over air cylinder controlling the roll-over stand to move, and a material roll-over stand used for placing the monitored pipes, and further comprises a lifting mechanism arranged on the roll-over stand, a first distance detection switch for detecting whether the roll-over stand receives the pipes and controls the lifting mechanism to move, and a second distance detection switch for controlling the roll-over air cylinder to move, wherein the second distance detection switch is arranged over the central positions of the pipes to be measured. Whether the pipes are qualifiedor not is judged by detecting the central distances of the pipes, the qualified pipes and the unqualified pipes are classified, and the equipment is simple in structure and practical and low in transformation input.

Description

technical field [0001] The invention relates to an on-line monitoring device and method for pipes, and more specifically, to an on-line monitoring device and method for products with unqualified bending of PVC pipes. Background technique [0002] The bending degree of long strips (types, rods, pipes) in the length direction. The bending chord height per meter of length is the bending degree per meter; the ratio of the total bending chord height to the total length of the total length is the total bending degree. The bending degree of various rolled pieces is stipulated in the product standard. The reason for the bending of the metal material is that the cooling rate is uneven during thermal processing or heat treatment, the shrinkage is inconsistent, the rolled piece is not straightened before cooling, and it is bent during transportation. [0003] When plastic pipes are extruded, the shrinkage rate varies with the flow direction, that is to say, the shrinkage rate in the ...
