Problems solved by technology

However, some pipe fittings have many arcs and complex dimensional chains, so they cannot be bent on CNC equipment and can only be processed by hand.
For this type of pipe fittings, it is required to measure the arc dimensions of each pipe fitting and related dimension chains. The detection workload is large and the efficiency is low, and it is difficult to ensure the consistency of mass-produced pipe fittings.

Abstract

The invention discloses a bend tube detection device and an application thereof. The bend tube detection device is formed by bending a red copper tube, or a steel tube, or a stainless steel tube. The bend tube detection device comprises an extension end, a tail end and a plurality of sequentially-connected arcs. The diameter of each arc is 60-160 mm, and the central angle of each arc is 30-280 degrees; and the surfaces of the extension end, the tail end and the arcs are respectively provided with a 0.2-0.5 mm antifriction layer. Serving as a casting mould and a detection comparison tool, the bend tube detection device, in the same plane, can bend a plurality of different radiuses of arcs and mould metal pipes, and can ensure uniformity of bend tube pipe moulding and improve processing efficiency; and serving as the detection comparison tool, the bend tube detection device can detect the pipes quickly, and improves pipe molding processing and detection efficiency by more than 50 %; by adding the antifriction layer, bonding force between molecules can be improved, and the antifriction layer can be attached to the surface of each metal pipe, and has good resistance to high temperature, chemical corrosion and friction, thereby improving service life of the bend tube detection device.

Description

technical field [0001] The invention belongs to the field of forming and processing of pipe fittings with many arcs and complex size chains in the pipeline system of special vehicles, and specifically relates to a bent pipe detection device and its application. Background technique [0002] In the existing special vehicle oil, water and gas pipeline system, after the pipeline system is assembled, it should be arranged neatly and orderly, horizontally and vertically. Therefore, it is required that the shape of the mass-produced formed pipe fittings should be consistent. However, some pipe fittings have many arcs and complex dimensional chains, so they cannot be bent on CNC equipment and can only be processed by hand. For this type of pipe fittings, it is required to measure the dimensions of each arc of each pipe fitting and the related dimension chain. The inspection workload is large and the efficiency is low, and it is difficult to ensure the consistency of mass-produced ...
