Plastic deformation measuring system and method for austenitic stainless steel stamped seal head

Abstract

The invention relates to the stamped seal head quality detection technology, and aims to provide a plastic deformation measuring system and method for an austenitic stainless steel stamped seal head. The system comprises a guiding measuring tape and a measuring platform with guiding wheels on the bottom. An L-shaped slot is arranged in the front end of the measuring platform and movably installed in the measuring platform through a warp-wise scribing driving rod and a circumferential scribing driving rod, one end of the warp-wise scribing driving rod and one end of the circumferential scribing driving rod are amplified in a taper shape and are respectively and movably installed in a vertical chute in an adjustable ring. A laser head is sleeved inside the adjustable ring and connected to a laser generator through fiber, and the rear end of the measuring platform is provided with a stay wire displacement sensor, a stay wire guide rod angle adjusting turn button, a stay wire guide rod and a stay wire guide wheel. The precision is high and reading error is reduced. Laser scribing ensures high efficiency, high precision and low cost. Damage on material surface is small, and influence on the surface performance of seal head material is minimal. Mark is permanent, mark traceability is enhanced, and the application scope is expanded.

Description

technical field [0001] The invention relates to a quality detection technology of a stamped and formed head, in particular to a measurement system and method for the plastic deformation of a stamped and formed head. Background technique [0002] With the implementation of the national clean energy strategy, the domestic demand for liquefied natural gas (LNG) and other clean energy is growing rapidly. As one of the main storage and transportation equipment for LNG, austenitic stainless steel (such as S30408) cryogenic containers are also in increasing demand. Big. As one of the core components of the cryogenic container, the performance of the head is related to the safety of the container product, so higher requirements are put forward for the quality of the head. The stamping forming process is widely used in the manufacture of small and medium-sized cryogenic containers, such as the stamping and forming of heads, due to its high processing precision, good surface quality,...

AI Technical Summary

Problems solved by technology

Compared with the traditional scribing measurement method, it solves the problem that the mark is easy to lose and the mark is easy to damage the surface of the head. At the same time, it reduces the manual error, improves the scribing efficiency and measurement accuracy, and is also suitable for convex heads of different sizes. Plastic deformation measurement
