Problems solved by technology

The performance test of materials in a low temperature environment needs to simulate low temperature. Most of the existing methods are to place the impact specimen in a low temperature environment for a certain period of time. When the temperature of the impact specimen reaches the test temperature, the specimen is quickly Take it out from the low-temperature environment and place it on the experimental mechanism for testing. Due to many unstable factors in the manual movement of the sample, such as the moving time and the contact area with the human body, the temperature of different samples will be different, which will affect the accuracy of the test results.

Abstract

The invention provides a toughness detection device, comprising an impact component, an insulation box and a control system. The impact component is a pendulum impact component connected with a pushing device and includes an impact table and a pendulum arranged above the impact table; the insulation box is arranged between the impact table and the pushing device and connected with a low-temperature source; a horizontal push rod of the pushing device can axially extend through the insulation box. The toughness detection device has the advantages that cooling, pushing and impacting at low temperature are achieved for a sample through coordinated control of the control system; the influence of manual operation destabilizing factors upon experimental results is avoided; time from sample cooling to impacting is shortened; experimental accuracy is improved; the toughness detection device is reasonable in structure and simple to mount; the control system has a storage function, test data arestored in a magnetic disk; secondary analysis of the test data, management of a data base and network transmission are facilitated.

Description

technical field [0001] The invention relates to an impact device, in particular to a toughness detection device. Background technique [0002] my country has a vast territory, and some transmission towers are located in areas with lower temperatures, and low temperature will increase the brittleness of steel, which is customarily called low-temperature cold brittleness; the low-temperature environment also has a great impact on the impact performance of steel, and the resulting brittleness of steel for transmission towers Fracture accidents occur frequently, causing serious damage; the low temperature toughness of steel structures of transmission towers has gradually attracted people's attention. [0003] The breaking strength of the material needs to be determined by impact test. The performance test of materials in a low temperature environment needs to simulate low temperature. Most of the existing methods are to place the impact specimen in a low temperature environment ...
