Description

Technical Field

[0001] The utility model relates to the technical field of bellows detection, in particular to a bellows stretch detection device which is easy to disassemble and assemble. Background Art

[0002] Bellows is a metal tube that is used as a flexible connector or for transferring fluids, gases or heat in many industrial applications. Bellows need to be tensile tested after production. The tensile test can determine the mechanical properties of the bellows material, such as strength and toughness. Understanding the tensile properties of the material can ensure that it meets engineering standards and design requirements, and it also helps to detect manufacturing defects and ensure product quality. The tensile test can evaluate the deformation and damage of the bellows under pressure loading, thereby ensuring its safety and reliability within the designed working range.

[0003] At present, when performing tensile testing on bellows, both ends of the bellows need to be fixed and then stretched. However, when fixing, bolts are mostly used for squeezing and fixing. When testing different pipelines, repeated disassembly reduces the test efficiency and also increases manpower consumption. In view of this, we propose a bellows tensile testing device that is easy to disassemble and assemble. Utility Model Content
