A device for measuring impact toughness with a fixed hammer

Abstract

The invention relates to the technical field of steel detection, and discloses a device for measuring impact toughness with a fixed hammer, including a base, the upper surface of the base is fixedly connected with a support column, and the upper end of the support column is fixedly connected with a disc , the middle part of the disc is movably connected with a roller, the middle part of the roller is movably connected with a wheel ring, the inside of the wheel ring is fixedly connected with sawtooth, the inside of the wheel ring is movably connected with a baffle plate, the The side of the wheel ring close to the socket of the rib is movably connected with a bearing, the middle of the bearing is fixedly connected with a rotating rod, and the end of the rotating rod far away from the bearing is movably connected with a hammer, and the hammer can be used as a fixed measuring device for impact toughness , through the sawtooth fixedly connected in the wheel ring, the hammer falls, and the wheel ring rotates, because the direction of the sawtooth is opposite to the direction of the baffle plate, when the hammer is lifted to the highest point to fall, the rotating rod drives the bearing to fall back, and the wheel ring also turns. At this time, the baffle plate is stuck on the sawtooth, the wheel ring cannot turn, 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...
