Embodiment

[0024] A dynamic monitoring device for the shrinkage of the inner diameter of the wound metal liner, its structure is as follows figure 1 As shown, the device includes a base 2 , a connecting bracket 3 , an eddy current displacement sensor 4 , and a fixing bracket 5 . The bottom end of the connecting bracket 3 used is connected on the base 2, and the top is provided with a fixed bracket 5 in a ring or arc-shaped structure. The fixed bracket 5 used in this embodiment is an arc-shaped structure, which is convenient to put in The metal liner 1 to be detected is conveniently specified. A double number of eddy current displacement sensors 4 are arranged in the fixed bracket 5 and are evenly distributed on the inner surface of the fixed bracket 5 . The metal liner 1 to be detected is arranged in the area surrounded by the fixed bracket 5 . In order to obtain better detection accuracy, the area surrounded by the metal liner 1 and the fixing bracket 5 is arranged concentrically.

Abstract

The invention relates to a dynamic monitoring method and device for inner diameter shrinkage of a winding metal inner container. An electric eddy current displacement device is monitored on the periphery of the wound metal inner container and used for monitoring multi-point deformation of a section in real time in the winding process of the metal inner container, so that dynamic monitoring of theinner diameter shrinkage amount of the winding metal inner container is realized. According to the method and the device, the inner diameter change of the winding metal inner container is measured inreal time through the eddy current displacement method, accurate and effective process monitoring data can be provided for technological parameter research of the winding metal inner container, then the design of an improved or optimized winding scheme is further realized, and the product quality can be monitored in real time in the production of winding products as well.

Description

technical field [0001] The invention relates to a monitoring method, in particular to a method and a device for dynamically monitoring the inner diameter shrinkage of a wound metal liner. Background technique [0002] In the field of winding technology, winding metal liner is a production process widely used in composite gas cylinders, composite pressure pipe fittings and other products. By winding fiber materials, etc., on the surface of the metal liner (such as steel, aluminum alloy and titanium alloy, etc.) with increased tension, the metal liner is under pressure in the initial state, thereby improving the elastic working range of the overall structure of the product, and improving the quality of the product. Purpose of rated working pressure. However, there is no method for real-time monitoring of the shrinkage of the inner diameter of the metal liner in the prior art. Contents of the invention [0003] The purpose of the present invention is to provide a dynamic mo...
