Special steel compressive strength detection device

Abstract

The invention is suitable for the technical field of special steel, and particularly relates to a special steel compressive strength detection device which comprises a base and a supporting frame, a supporting column is arranged on the surface of the base, a lantern ring for fixing steel is arranged on the supporting column, a fixing mechanism is arranged in the lantern ring, and pressing rods are arranged on the two sides of the supporting column. A channel allowing steel to penetrate through is formed in the pressing rod, the channel and the lantern ring are located on the same horizontal plane, a cavity is formed in the base, and a detection mechanism is arranged in the cavity. According to the device, the lifting mechanism drives the pressing rod to move downwards, the pressing rod extrudes the two ends of the steel through the channel while moving downwards, so that the two ends of the steel move downwards, then the steel is bent, and due to the fact that the channel is movably connected with the steel, the channel slides relative to the steel when the steel is bent downwards; and the steel is prevented from being stressed in the horizontal direction, and the accuracy of detecting the compressive strength of the steel is improved.

Description

technical field [0001] The invention relates to the technical field of special steel, in particular to a device for detecting the compressive strength of special steel. Background technique [0002] Special steel is different from traditional steel. It is mainly composed of alloys. It generally has good oxidation resistance, corrosion resistance, and high temperature resistance. It can be used in extremely harsh environments and is mostly used in special industries. Therefore, special steel is in production. After completion, its compressive strength needs to be tested. [0003] In the prior art, the method for testing the compressive strength of special steel is generally to put the steel on the detection device, then clamp and fix the two ends of the steel, and then apply pressure to the middle part of the steel to exert pressure on the steel During the process, the steel will bend back, and the pressure sensor will be squeezed through the bent part of the steel, and the ...

Problems solved by technology

[0004] However, in the process of testing the compressive strength of this kind of steel, because the middle part of the steel will bend downward, it will drive the two ends of the steel to approach each other. In addition to the pressure, it will also be subjected to horizontal tension from the fixtures at both ends of the steel, which will cause certain errors in the test results.
