Description

Technical Field

[0001] The utility model belongs to the technical field of steel material processing, and in particular relates to a steel sample fixing fixture device. Background Art

[0002] With the advancement of steel industry technology, new types of steel and special-purpose steels are emerging in an endless stream. They not only have to meet various engineering design requirements, but their inherent mechanical properties, especially impact toughness, have also become important indicators for measuring product quality and safety and reliability. In the practice of impact performance inspection of steel, in order to ensure the accuracy of data and the efficiency of the inspection process, higher requirements are placed on impact specimens. The size control of the blank specimens used in the impact performance inspection test is particularly critical, and the length of the specimen is usually required to be controlled within the range of ±0.5mm. If the length of the blank specimen exceeds the tolerance limit, it will directly lead to the final size of the impact specimen being unqualified, which will in turn affect the reliability and reproducibility of the entire test results. As a result, the impact characteristics of the steel material itself cannot be truly reflected.

[0003] Therefore, in the process of implementing the impact performance test for new or special types of steel, in order to ensure the validity and accuracy of the test data, the relevant technicians faced many challenges when preparing the steel specimens required for the impact test. One of the key links is the sawing of the specimen, which depends on the operation of the metal band saw. Because the original fixture of the metal band saw does not have a measuring device, this means that when processing the blank specimen required for each impact test, the operator has to repeatedly measure the preset length of the specimen manually.

[0004] This manual measurement method not only consumes a lot of valuable working time, but also, especially in a mass production environment, each individual manual measurement will accumulate into a significant time cost in the overall process. On the other hand, manual measurement inevitably introduces potential dimensional errors, which may be caused by human factors such as visual judgment or differences in operating techniques, which may cause the processed specimen size to deviate from the standard requirements, directly affecting the reliability of subsequent impact test results.

Rotate the wrench rod B 312 until the lower end surface of the pressing head 314 presses the upper surface of the profile, and the profile is pressed and fixed.

[0045] 7. Start the sawing machine 1, and the sawing machine 1 starts cutting the profile.

[0046] 8. After the cutting is completed, the pressure head 314 is lifted upwards, and the cut profile sample is manually taken away.

[0047] 9. The bottom of the pressing head 314 is set to a V-shaped structure to achieve the V-shaped fixing effect on the rod. Certain planes 316 are set on both sides of the V, and the planes 316 can achieve pressing of the profile whose upper surface is the plane 316.
