Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3 , a special processing center machine tool for metal sheet tensile specimens, comprising a first clamping block 1 and a second clamping block 4, the second clamping block 4 is horizontally slidably clamped and installed on one side of the first clamping block 1, a clamping cylinder 2 is fixedly installed on one side of the first clamping block 1, the ejection end of the clamping cylinder 2 is fixedly connected to the second clamping block 4, a metal sheet sample 3 is clamped and installed between the first clamping block 1 and the second clamping block 4, and the second clamping block 4 is driven to move horizontally along the first clamping block 1 through the extension and contraction of the clamping cylinder 2, and is used to telescopically clamp the lower end of the metal sheet sample 3, a corrugated groove 13 is provided on the left clamping end face of the first clamping block 1, and a corrugated protrusion that matches the corrugated groove 13 is provided on the right end face of the second clamping block 4, which is used to clamp the lower end of the metal sheet sample 3 in a corrugated shape, increase the friction force of the lower end of the metal sheet sample 3, and prevent the metal sheet sample 3 from detaching from the first clamping block 1 and the second clamping block 4 during the subsequent stretching.

[0023] In this embodiment, a support plate 5 is fixedly installed on the upper end of the first clamping block 1, and a guide block 1 6, a guide block plate 2 7 and a hydraulic cylinder for a sample are installed on both sides of the upper end of the support plate 5. The guide block 1 6 and the guide block plate 2 7 are respectively fixedly installed on both sides of the upper end of the support plate 5. The cylinder body 9 in the hydraulic cylinder for the sample is fixedly installed on the top of the support plate 5. The hydraulic cylinder for the sample also includes a piston rod 8. The upper end of the piston rod 8 is telescopically installed in the cylinder body 9. The hydraulic cylinder for the sample is arranged at the upper end of the metal plate sample 3.

[0024] In this embodiment, a one-piece clamp is provided at the lower end of the piston rod 8 in the hydraulic cylinder for the specimen, and an inclined plate 21 for transmitting kinetic energy is hinged between the one-piece clamp and the piston rod 8. The one-piece clamp is composed of a third clamp block 10 and a fourth clamp block 12. A slider 11 is fixedly provided on the left side of the third clamp block 10. The guide block plate 27 and the slider 11 are always in contact with each other, specifically in sliding contact with the right side wall or the lower side wall of the slider 11. The fourth clamp block 12 is slidably connected to the left side wall of the guide block 16. A connecting plate 18 is hinged at the top end of the inclined plate 21. The connecting plate 18 is fixedly connected to the end of the piston rod 8. A telescopic rod 19 is fixedly installed at the lower end of the connecting plate 18. The telescopic rod 19 is vertically telescopically installed in the fourth clamp block 12.

[0025] In this embodiment, a guide mechanism is arranged between the third clamping block 10 and the fourth clamping block 12, and the guide mechanism is composed of a fixed block 17, a guide rod 16 and an inner hole guide block 15. The inner hole guide block 15 is fixedly installed on the top of the third clamping block 10, the fixed block 17 is fixedly installed on the top of the fourth clamping block 12, the guide rod 16 is fixedly installed on one side of the fixed block 17, and the guide rod 16 slides through the inner hole guide block 15, that is, the third clamping block 10 is horizontally slidably installed on the left side of the fourth clamping block 12 through the fixed block 17, the guide rod 16 and the inner hole guide block 15, and a rubber spring 20 is fixedly installed between the third clamping block 10 and the fourth clamping block 12. The rubber spring 20 in this application is always in a compressed state, and is used to automatically push the third clamping block 10 to the left away from the fourth clamping block 12, so as to automatically open the third clamping block 10 and the fourth clamping block 12.

[0026] It should be noted that the specific process of clamping the top of the metal sheet sample 3 by the one-piece clamp is as follows: first, the top of the metal sheet sample 3 is placed between the third clamp 10 and the fourth clamp 12 in the one-piece clamp, and then the piston rod 8 in the sample hydraulic cylinder is directly contracted and moved upward along the cylinder body 9, pulling the top of the inclined plate 21 to move upward, and the upper end of the slider 11 is pulled by the lower end of the inclined plate 21 to move rightward along the lower end surface of the guide plate 7, thereby pushing the third clamp 10 on the right side to move rightward, and clamping the top of the metal sheet sample 3 between the third clamp 1 0 and the fourth clamp block 12, and the third clamp block 10 and the fourth clamp block 12 are provided with a corrugated groove 2 14 on the left side, and the right side of the third clamp block 10 is fixedly provided with a convex block that matches the corrugated groove 2 14, so that when the third clamp block 10 and the fourth clamp block 12 are close to each other and squeezed, the top end of the metal sheet sample 3 is bent and deformed along the shape of the inner wall of the corrugated groove 2 14, thereby increasing the friction between the third clamp block 10, the fourth clamp block 12 and the metal sheet sample 3, and preventing the metal sheet sample 3 from detaching from the third clamp block 10 and the fourth clamp block 12 when stretched later;

[0027] Until the left side wall of the slider 11 and the right side wall of the guide plate 7 are in the same vertical plane, as the piston rod 8 continues to move upward, the third clamping block 10 and the fourth clamping block 12 are pulled upward along the right side wall of the guide plate 7 and the left side wall of the guide block 6 through the inclined plate 21 and the slider 11, so as to stretch the top of the metal sheet sample 3 clamped between the third clamping block 10 and the fourth clamping block 12 upward for a tensile test;

[0028] As can be seen from the above, as the piston rod 8 moves upward, the horizontal clamping and vertical stretching actions of the one-piece clamp can be automatically pulled by the inclined plate 21, thereby eliminating the need to clamp the top of the metal sheet sample 3 separately, and the clamping efficiency is high.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
