The data obtained from the tensile test can be used to determine the elastic limit, elongation, elastic modulus, proportional limit, area reduction, tensile strength, yield point, yield strength and other tensile performance indicators of the material.

[0003] When conducting traditional tensile tests, it is necessary to fix both ends of the test piece. When dealing with heavier test pieces, the operation is inconvenient. At the same time, after the test piece breaks at the tensile peak, it will swing laterally, which is relatively dangerous. Based on this, the utility model proposes a tooling for a tensile testing machine that can solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tooling for a tensile testing machine to solve the problems raised in the above background technique.

[0009] As a preferred technical solution, a plurality of anti-slip protrusions are arranged on the lifting plate.

[0010] As a preferred technical solution, a plurality of guide rollers are arranged on the support table.

[0011] As a preferred technical solution, the isolation component includes a cover body and a second electric cylinder body. The cover body is movably sleeved on the support plate, and the movable end of the second electric cylinder body is connected with the cover body, and can push the cover body to move upward to accommodate the first traction block and the second traction block therein.

[0012] As a preferred technical solution, a buffer rubber layer is provided on the inner wall of the cover body.

Detailed Embodiments

[0024] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , and a tooling for a tensile testing machine is provided, aiming to solve the problems that it is inconvenient to operate when facing a heavy test piece during tensile test, and the test piece will swing laterally after breaking at the tensile peak, with relatively high danger. The specific embodiments are as follows:

[0026] Embodiment 1

[0027] The support table 10 has a socket 11. The lifting component 40 includes a first electric cylinder body 41 installed in the socket 11. There are multiple groups of the first electric cylinder bodies 41. The movable end of the first electric cylinder body 41 is connected with a lifting plate 42. Both ends of the lifting plate 42 respectively form a countersunk head area 45 with the socket 11. Baffles 43 are respectively arranged on both sides of the lifting plate 42.

[0028] Before the tensile test on the test piece, the test piece is placed on the support table 10 and laterally pushed into the socket 11. A plurality of guide rollers 12 are arranged on the support table 10 to reduce the frictional resistance when moving on the support table 10 into the socket 11. The lifting plate 42 plays a supporting role for the main body part of the test piece. Both ends of the test piece respectively hang down into the countersunk head area 45. By driving the lifting plate 42 to move vertically through the first electric cylinder body 41, the height of the test piece relative to the lifting plate 42 can be adjusted. And through the arranged baffles 43, it can be avoided that the test piece rolls off the lifting plate 42 during the vertical movement. A plurality of anti-slip protrusions 44 are arranged on the lifting plate 42, so that the test piece is not easy to slide and fall on the lifting plate 42.

[0029] The connecting component 30 includes a first track 31 and a second track 32. The first track 31 and the second track 32 are vertically symmetrically distributed on the support table 10 with the socket 11 as the center, that is, the first track 31 and the second track 32 are respectively distributed at one end of the socket 11.

[0030] A first traction block 33 is slidably connected to the first track 31, and a second traction block 34 is slidably connected to the second track 32. Limit blocks 36 are respectively arranged at both ends of the first track 31 and the second track 32. Hooks 35 for hooking the test piece are arranged on both the first traction block 33 and the second traction block 34. By the arranged limit blocks 36, it can be prevented that the first traction block 33 and the second traction block 34 slide off the corresponding tracks.

[0031] Specifically, the first cylinder body drives the lifting plate 42 to move upward away from the embedding groove 11, and drives the test piece above the first traction block 33 and the second traction block 34. The two ends of the test piece droop downward respectively. By sliding the first traction block 33 and the second traction block 34 close to the test piece in sequence, the two ends of the test piece are respectively hooked on the hook 35, and then the first electric cylinder body 41 is controlled to drive the lifting plate 42 to move downward to disengage from the test piece, forming a pull on the test piece, effectively reducing the operation difficulty for a heavier test piece;

[0032] During the test, the first traction block 33 is blocked by the limit block 36 near the embedding groove 11, and then the second traction block 34 is pulled away from the first traction block 33 by the tensile testing machine 13 to conduct a tensile test on the test piece. The connection between the tensile testing machine 13 and the second traction block 34 selects connection methods such as bolt connection and welding;

[0033] After the experiment is completed, when the test piece breaks, it can droop downward onto the lifting plate 42. Thus, when removing the test piece that has broken in the test, the first cylinder body can be used to drive the lifting plate 42 to lift upward again, further improving the convenience of the test.

[0034] Embodiment Two

[0035] An isolation assembly 20 is arranged on the support table 10. The isolation assembly 20 includes a cover body 22 and a second electric cylinder body 21. The cover body 22 is movably sleeved on the support plate. There are multiple groups of the second electric cylinder bodies 21. The movable end of the second electric cylinder body 21 is connected to the cover body 22, and can push the cover body 22 to move upward to accommodate the first traction block 33 and the second traction block 34 inside. A buffer rubber layer is arranged on the inner wall of the cover body 22.

[0036] During the test, the second electric cylinder body 21 is used to drive the cover body 22 to move upward to isolate the test piece inside, blocking the risk of lateral swinging when the test piece breaks, effectively improving the safety.

[0037] Embodiment Three

[0038] Both the first track 31 and the second track 32 are wedge-shaped tracks. A limit rod 331 is screwed on the first traction block 33. Multiple holes 311 are arranged on the first track 31, and the limit rod 331 can be screwed into the holes 311 to lock the first traction block 33.

[0039] When facing a longer test piece, when the first traction block 33 is blocked by the limit block 36 near the embedding groove 11 and the stroke of the tensile testing machine 13 is insufficient, the first traction block 33 can be first slid on one track away from the second traction block 34, and then the limit rod 331 is tightened into the hole 311 to lock the first traction block 33, and then the second traction block 34 is pulled by the tensile testing machine 13 to move for the experiment, with good experimental adaptability.

[0040] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
