A cylindrical die steel toughness detection device

Abstract

The invention discloses a cylindrical mold steel toughness testing device, which comprises a casing, a toughness testing cavity is arranged inside the casing, a transverse movement mechanism is arranged inside the toughness testing cavity, a clamping mechanism is arranged at the upper end of the transverse movement mechanism, and a toughness testing cavity There is a lifting mechanism on the rear end wall of the steel pipe, through the lifting mechanism, the detection worm and the profiling worm wheel are used to realize the lifting of the steel to achieve the purpose of toughness detection, and the detection worm and profiling worm gear are formed at the same time. The worm gear structure has a self-locking function, which can stop at any position during the toughness test of the steel, which facilitates a more intuitive observation of the physical properties and surface strength changes of the steel during the test. The existing gap difference prevents the small deformation of the steel from rebounding when stopped, ensuring the reliability of the toughness test.

Description

technical field [0001] The invention relates to the technical field of detection, and more particularly relates to a cylindrical die steel toughness detection device. Background technique [0002] Cylindrical mold steel is widely used in the field of construction. Because of its good rigidity, it is often used for the load-bearing parts of buildings. Therefore, it is necessary to carry out toughness testing when it is used, but the traditional testing lacks necessary equipment. , mainly through artificial bending to determine whether the steel has good toughness and flexural strength. This method has no way to determine the specific toughness range of the material, and the results are not convincing. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a cylindrical die steel toughness testing device, the technical solution is: [0004] A cylindrical mold steel toughness testing device according to the present invention...
