Description

Technical Field

[0001] The utility model belongs to the technical field of tensile testing of profiles, and particularly relates to a transverse tensile testing tooling for building heat insulation profiles of profiles. Background Technique

[0002] Aluminum alloy heat insulation profiles are a new type of building material with aluminum as the main body and plastic profile cavities as heat insulation materials in the middle of the profiles. This innovative structural design of plastic and aluminum combines the advantages of both materials, and at the same time meets various requirements of decorative effects, door and window strength, and aging resistance.

[0003] During the design and production process of aluminum alloy heat insulation profiles, it is necessary to conduct transverse tensile tests on them to verify their load-bearing capacity by testing the tensile properties and elastic modulus of aluminum alloy heat insulation profiles during transverse tensile processes. The currently used transverse drawing test fixtures, such as Figure 1 shown, include two testing toolings corresponding up and down. The testing tooling has a "C" - shaped structure. During testing, after a rigid support bar is inserted into the interior of the aluminum alloy profile, the rigid support bar is clamped inside the testing tooling, and then the tensile test is started; there is a separation between the two testing toolings of this transverse drawing test fixture. At the same time, the aluminum alloy profile is movably sleeved outside the rigid support bar. There is a lack of positioning between the aluminum alloy profile and the rigid support bar, as well as between the rigid support bar and the testing tooling. During drawing, the center lines of the two upper and lower testing toolings deviate from the force - bearing axis of the profile specimen, which further exacerbates the deflection of the profile specimen and affects the progress of the test.

[0004] Therefore, it is necessary to design a transverse tensile testing tooling for building heat insulation profiles of profiles that can improve the positioning accuracy between the rigid support bar, the aluminum alloy profile, and the testing tooling, make the center lines of the two upper and lower testing toolings coincide with the force - bearing axis of the profile specimen, and ensure the testing effect to solve the current technical problems. Summary of the Invention

[0005] Aiming at the deficiencies in the prior art, the utility model provides a transverse tensile testing tooling for building heat insulation profiles of profiles that can improve the positioning accuracy between the rigid support bar, the aluminum alloy profile, and the testing tooling, ensure that the center lines of the two upper and lower testing toolings coincide with the force - bearing axis of the profile specimen, and further ensure the testing effect.

[0006] The technical solution of the utility model is: a transverse tensile testing tooling for building heat insulation profiles, including a top plate. An installation column is arranged at the top of the top plate. Side plates are arranged at the bottoms of both ends of the top plate. A support plate is fixedly arranged at the bottom end of one side corresponding to each other between the two side plates. A limiting plate is arranged at one end of the support plate away from the side plate. A positioning mechanism is arranged at the end of the limiting plate. A jack is arranged on the side plate, and a support plate is slidably arranged inside the jack.

[0007] The positioning mechanism comprises a support plate fixedly arranged at the end of the limiting plate, a screw rod is vertically threadedly connected to the support plate, and a hand wheel is fixedly arranged at one end of the screw rod away from the limiting plate.

[0008] A spherical head is arranged on the end of the screw rod away from the hand wheel.

[0009] A slideway is provided inside the support plate along the support plate, and a limit bolt matching the slideway is provided inside one of the insertion holes, and the limit bolt is slidably connected to the slideway.

[0010] The top of the limiting plate is flush with the top of the supporting plate, and the top of the supporting plate is flush with the bottom of the plug hole.

[0011] The distance between the two limiting plates is 100-105 mm.

[0012] The support plate, side plate and top plate are an integrated structure.

[0013] The beneficial effects of the utility model are as follows: the utility model limits the two ends of the profile sample by two limit plates, and cooperates with the positioning mechanism to position the front and back sides of the profile sample, and then the support plate is inserted into the interior of the aluminum alloy profile to start testing, which can improve the positioning accuracy between the support bar and the profile sample and the testing tooling, ensure that the center lines of the upper and lower testing tools coincide with the force axis of the profile sample, thereby ensuring the testing effect.

[0019] Various exemplary embodiments of the present utility model will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is not intended to limit the present utility model or its application or use. The present utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present utility model thorough and complete, and to fully convey the scope of the present utility model to those skilled in the art. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, the compositions of materials, numerical expressions and values set forth in these embodiments should be construed as merely exemplary and not as limitations.

[0020] The "first", "second" and similar terms used in the present utility model do not denote any order, quantity or importance, but are only used to distinguish different parts. Words such as "comprising" or "including" mean that the elements before the word cover the elements listed after the word, and do not exclude the possibility of also covering other elements. "Upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0021] As Figures 2 to 5 shown, a transverse tensile testing tooling for building thermal insulation profiles includes a top plate 1. An installation column 4 is provided at the top of the top plate 1. Side plates 2 are provided at the bottoms of both ends of the top plate 1. A support plate 3 is fixedly provided at the bottom end of one side corresponding to each other between the two side plates 2. A limiting plate 5 is provided at the end of the support plate 3 away from the side plate 2. A positioning mechanism 6 is provided at the end of the limiting plate 5. A jack 7 is provided on the side plate 2. A support plate 8 is slidably arranged inside the jack 7. In this embodiment, a profile specimen with a length adapted to the distance between the two limiting plates 5 is cut during the experiment for the aluminum alloy thermal insulation profile. When installing the profile specimen into the tooling, the two limiting plates 5 are used to limit the two ends of the profile specimen, and at the same time, the positioning mechanism 6 is used to position the front and rear sides of the profile specimen. Then, the support plate 8 is inserted into the interior of the aluminum alloy profile to start the detection, which can improve the positioning accuracy between the support bar, the profile specimen and the testing tooling, ensure that the center lines of the upper and lower two testing toolings coincide with the force axis of the profile specimen, and thus ensure the detection effect.

[0022] In some embodiments, as a specific implementation manner of the positioning mechanism 6, as Figure 3As shown, the positioning mechanism 6 has a support plate 61 fixedly arranged at the end of the limit plate 5. A screw rod 62 is vertically threadedly connected to the support plate 61. A hand wheel 63 is fixedly arranged at one end of the screw rod 62 away from the limit plate 5. By rotating the screw rod 62 through the hand wheel 63, the screw thread structure between the screw rod 62 and the support plate 61 is matched, and the end of the screw rod 61 close to the profile sample can be moved. By adjusting the screw rods 62 on both sides of the profile sample, the profile sample can be centered front and back in the detection tooling; in order to avoid the friction between the end of the screw rod 62 and the profile sample from affecting the detection accuracy, the end of the screw rod 62 and the profile sample can be separated when the tensile force reaches a certain value and then the test can be continued.

[0023] In some embodiments, a spherical head 64 is arranged at one end of the screw rod 62 away from the hand wheel 63. Compared with a flat head, the contact area between the spherical head 64 and the profile sample is smaller, and the friction force is relatively smaller.

[0024] In some embodiments, as Figure 5 shown, a slideway 81 is arranged along the inside of the support plate 8. A limit bolt 9 matching the slideway 81 is arranged inside one jack 7. The limit bolt 9 is slidably connected to the slideway 81. The support plate 8 slides inside the jack 7, and the limit effect of the limit bolt 9 can prevent the support plate 8 from slipping out of the jack 7 and being lost. When the support plate 8 is inserted in place inside the other jack 7, the limit bolt 9 just abuts against one end inside the slideway 81, playing a role in limiting the insertion of the support plate 8.

[0025] In some embodiments, the top of the limit plate 5 is flush with the top of the support plate 3, and the top of the support plate 3 is flush with the bottom of the jack 7, so that the top of the limit plate 5, the top of the support plate 3 and the inner bottom of the jack 7 form a plane to provide support for the support plate 8.

[0026] In some embodiments, the distance between the two limit plates 5 is 100 - 105 mm; preferably, the distance between the two limit plates 5 is 103 mm. The length requirement of the profile sample in the arbitration sample is 100 mm ± 2 mm. The distance of 103 mm between the two limit plates 5 can enable the qualified profile sample to be placed between the two limit plates 5, and at the same time, there is a certain gap between the profile sample and the limit plates 5 to avoid the friction between the profile sample and the limit plates 5 from affecting the detection accuracy.

[0027] In some embodiments, the support plate 3, the side plate 2 and the top plate 1 are of an integral structure.

[0028] So far, the embodiments of the present invention have been described in detail. In order to avoid obscuring the concept of the present invention, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed here based on the above description.

[0029] The above-described embodiments only represent some implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
