Problems solved by technology

However, when the existing general-purpose universal material testing machine is used to test the bending strength of stainless steel pipes, it is not convenient to fix the steel pipes. It is necessary to ensure the stability of the clamping, and the steel pipe is separated from the clamping assembly, which poses a great potential safety hazard

Abstract

The invention discloses a stainless steel pipe bending resistance testing device which is characterized in that a first clamping arm and a second clamping arm are symmetrically arranged at the top end of a supporting base, a first supporting body and a second supporting body are arranged between the first clamping arm and the second clamping arm, and mounting bodies are arranged on the back faces of the first supporting body and the second supporting body; a lifting hydraulic cylinder is fixedly mounted at the top end of the mounting body, and a detection body is fixedly connected to the bottom end of the lifting hydraulic cylinder. The device has the beneficial effects that the two ends of the to-be-detected steel pipe are clamped at the same time through the clamping bodies of the first clamping arm and the second clamping arm, the clamping stability is improved through the hard rubber layer, meanwhile, the to-be-detected steel pipe is always clamped in the steel pipe clamping groove through the characteristic of the gravity of the to-be-detected steel pipe, and the detection accuracy is improved. The stability of the to-be-detected steel pipe during testing is further guaranteed, it is guaranteed that the to-be-detected steel pipe does not deviate, and the safety of a testing instrument is guaranteed.

Description

technical field [0001] The invention relates to a bending resistance test device, in particular to a stainless steel pipe bending resistance test device, which belongs to the technical field of steel pipe detection. Background technique [0002] Flexural strength refers to the ultimate breaking stress per unit area of ​​a material when subjected to a bending moment. Also known as flexural strength, modulus of rupture. The flexural strength test is divided into three-point bending and four-point bending. Each point requires more than 5 data (standard requires 10 data) and the average result. [0003] When testing the flexural strength of general materials, a universal universal material testing machine is generally used. However, when the existing general-purpose universal material testing machine is used to test the bending strength of stainless steel pipes, it is not convenient to fix the steel pipes. It is necessary to ensure the stability of the clamping. If the steel...
