Description

Technical Field

[0001] The utility model relates to the technical field of steel bar tensile testing machines, and particularly relates to a steel bar strength tensile testing machine. Background Art

[0002] A steel bar strength tensile testing machine is a test device used to test the strength and deformation properties of steel bar materials during the tensile process. In the construction and engineering fields, steel bars are a commonly used building material, often used to reinforce the strength of concrete structures. Therefore, it is very important to test the strength and deformation properties of steel bars. The steel bar strength tensile testing machine tests the performance of steel bars in the tensile state by applying different magnitudes of tensile force. Important parameters such as the yield strength, tensile strength, and elastic modulus of the steel bars can be obtained through testing. These parameters are crucial for designing engineering structures and determining the reliability of materials.

[0003] Among them, Chinese Patent (CN219434543U) discloses a steel bar strength tensile testing machine, the abstract or including a first clamping table and a second clamping table. Both sides of the first clamping table and the second clamping table are connected with clamping plates through first hydraulic rods. The upper surfaces and bottoms of the first clamping table and the second clamping table are provided with fitting grooves. There are two groups of fitting grooves, which are respectively connected with a lower shielding cover and an upper shielding cover through a first fitting plate and a second fitting plate. The inner surface of the lower shielding cover is provided with a track groove. The utility model effectively realizes the shielding of waste chips generated during the steel bar strength tensile testing process, avoids the phenomenon that waste chips fly randomly and cause accidental injury to operators, and can also make the lower shielding cover and the upper shielding cover automatically extend or contract during use, increasing the shielding range of the lower shielding cover and the upper shielding cover during use, and improving the safety of the steel bar strength tensile testing machine during use.

[0004] The deficiencies of the steel bar strength tensile testing machine in the above-mentioned comparative document: Although the waste chips generated during the steel bar strength tensile testing process can be shielded by the upper and lower shielding covers, the upper and lower shielding covers do not have a relatively large opening, so the waste chips may fly out from the opening and cause damage to the equipment or the staff, and the steel bars may be blocked by the upper and lower shielding covers when placing and taking out the steel bars, causing inconvenience in placing and taking out the steel bars;

[0005] Therefore, we have designed a steel bar strength tensile testing machine. Content of the Utility Model
