Multi-sensor fusion pipe fitting bending forming state real-time monitoring device

Abstract

The invention discloses a multi-sensor fused real-time monitoring device for the bending forming state of a pipe fitting. Comprising an in-pipe fixing device, a fast disassembly and assembly universal joint and bending state detection modules, the first bending state detection module is connected with the in-pipe fixing device through the fast disassembly and assembly universal joint, and the other multiple bending state detection modules are connected end to end through the fast disassembly and assembly universal joint to form an open chain structure and are limited and fixed in a pipe through the in-pipe fixing device. A linear displacement sensor, a metal thickness sensor and a gyroscope sensor of the bending state detection module are used for monitoring the section shape change, the wall thickness change and the springback information of the pipe fitting correspondingly, and the rapid disassembly and assembly universal joint can select the number of the bending state detection modules according to the length of the bending section of the pipe fitting to achieve rapid disassembly and assembly. The device is used for monitoring changes of pipe wall shapes, wall thicknesses and axis information of all positions of a pipe fitting bending section in the pipe fitting bending process in real time, pipe fitting bending dynamic information can be obtained, the bending test process is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of pipe fitting bending and forming, and in particular relates to a multi-sensor fusion real-time monitoring device for pipe fitting bending and forming state. Background technique [0002] As a structural part or a fluid transport carrier, bent pipe components are widely used in aviation, aerospace, ships, vehicles, and oil transportation. In engineering applications, various fields have strict requirements on the bending quality of pipes. Pipe fittings are processed into bent pipes through plastic deformation. When the pipe is bent and deformed, it is easy to produce such as cross-sectional distortion, pipe wall collapse, thinning or cracking on the convex side of the pipe wall, thickening or wrinkling on the concave side of the pipe wall, and springback after unloading The monitoring, prediction, and control of these forming defects in the bending process are problems that must be solved for high-quality bending of...

Problems solved by technology

Since the outer bending section of the pipe wall mostly leans against the mold during the bending process of the pipe, there is currently a lack of a real-time monitoring device installed in the pipe to monitor the pipe bending process in real time to obtain the real-time state of the pipe bending, so as to effectively predict the bending of the pipe process, make the bending equipment determine reasonable process parameters, and control the bending defects
