Description

Technical Field

[0001] The utility model relates to the technical field of steel materials, in particular to a three-station steel bar bending testing machine for engineering material detection. Background Art

[0002] The three-station steel bar bending test machine is a kind of equipment widely used in the field of engineering material testing. It is mainly used to perform bending tests on steel bars to evaluate their performance and quality in actual use. The three-station steel bar bending test machine usually consists of the following parts: bending frame, hydraulic system, control system and data acquisition system. The bending frame is the main structure of the three-station steel bar bending test machine, which is usually made of sturdy and durable metal materials. It has a stable structure and can withstand the bending force and pressure during the test. The hydraulic system is responsible for providing force and control during the test, and usually includes components such as hydraulic cylinders, oil pumps, and pressure sensors. The control system is the core part of the three-station steel bar bending test machine, which is mainly composed of computer control devices and related software. It can monitor and control the entire test process, including functions such as applying force, recording test data, and generating reports.

[0003] For example, a three-station steel bar bending tester for engineering material testing with the announcement number CN217688348U, in which different support blocks are required for different types of steel bars, and support rails are added to the interior of the horizontal table when different shapes of support blocks need to be replaced continuously, so that the upper slot of the support block faces upward. Since the upper slot is V-shaped, when testing steel bars with circular cross sections, the steel bars can be prevented from sliding, which is convenient for testing. When the upper slot of the support block faces upward, since the upper slot is V-shaped, when testing steel bars with circular cross sections, the steel bars can be prevented from sliding, which is convenient for testing. When testing steel materials with flat bottom surfaces such as steel plates, the pull rod is pulled outward, and then the support block is rotated to rotate the lower slot upward, and two lower slots are used to place steel materials. Since the lower slot is rectangular, it is convenient to place steel materials with flat bottom surfaces. Compared with the existing steel testing machine, the utility model can test different types of steel materials, and there is no need to replace the support block, which is more convenient to use.

[0004] However, in this patent, the diversity of test objects during use makes the adjustment of the device during testing cumbersome, affecting work efficiency. Utility Model Content

[0029] In this embodiment, the slider 113 moves on the top slide groove 112 to drive the connecting slide 114, and the connecting slide 114 drives the fixing frame 115 to move, and the fixing frame 115 is adjusted to adapt to the length of different test objects.

[0030] Example 2

[0031] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the width adjustment device 12 includes a back slide groove 121, a fixed platform 122, a baffle 123, a socket 124, an electric telescopic rod 125, and an opening 126.

Through the data acquisition system, we can obtain important information such as the mechanical properties and failure characteristics of the steel bar during the bending process. When using a three-station steel bar bending test machine for steel bar bending tests, we can adjust the parameters of the bending frame, such as the support spacing and loading speed, to simulate the stress environment in the actual project. At the same time, by recording the test data, we can evaluate the bending resistance, elastic deformation and failure characteristics of the steel bar to ensure that it meets the relevant standards and specifications. In short, the three-station steel bar bending testing machine plays an important role in engineering material testing. It can help us evaluate the bending performance and quality of steel bars, thereby ensuring the safety and reliability of engineering projects.
