Hammer-fixable device for measuring impact toughness

Abstract

The invention belongs to the technical field of steel detection and discloses a hammer-fixable device for measuring impact toughness. The device comprises a base; the upper surface of the base is fixedly connected with a supporting column; the upper end of the supporting column is fixedly connected with a disc; the middle part of the disc is movably connected with a rolling shaft; the middle partof the rolling shaft is movably connected with a wheel ring; saw teeth are fixedly connected in the wheel ring; baffles are movably connected in the wheel ring; one side of the wheel ring, which is close to rib inserting openings, is movably connected with a bearing; the middle of the bearing is fixedly connected with a rotating rod; and one end, away from the bearing, of the rotating rod is movably connected with a hammer. According to the hammer fixable device for measuring the impact toughness, the saw teeth fixedly connected in the wheel ring; the hammer falls, and the wheel ring rotates;the direction of the saw teeth is opposite to the direction of the baffles; after the hammer is raised to the highest point and falls down, the rotating rod drives the bearing to fall back, and the wheel ring also rotates; the baffles clamp the saw teeth at this moment, the wheel ring cannot rotate, and the hammer stops at the highest point.

Description

technical field [0001] The invention relates to the technical field of steel detection, in particular to a device for measuring impact toughness with a fixed hammer. Background technique [0002] Steel testing includes steel structure and special equipment raw materials, welding consumables, weldments, fasteners, welds, bolt ball joints, coatings and other material testing content, to test the mechanical properties of steel used in steel structures, such as tensile, Bending, impact, hardness, etc., impact toughness refers to the ability of a material to absorb plastic deformation work and fracture work under impact loads, reflecting the subtle defects and impact resistance inside the material, and can be divided into "V" according to the shape of the sample notch There are two types of impact tests: notch-shaped and "U"-shaped notch. When a metal sample of a certain size and shape is broken by an impact load in a specified type of impact test, the impact energy consumed on t...
