Description

Technical Field

[0001] The utility model relates to the field of adhesive testing, specifically a tensile shear and peel specimen preparation tooling. Background Art

[0002] The tensile shear strength and peel strength test specimens of adhesives are important carriers for verifying the mechanical performance indicators of adhesives. Through the detection of the specimens, the mechanical properties of the adhesives can be directly obtained. Compared with the detection of product physical objects, the cost and difficulty are greatly reduced. However, at the same time, due to the differences in specimen preparation, the accuracy of the detection results may be affected, causing trouble in determining the strength of the adhesives. Therefore, national standards or industry standards have stipulated the requirements for specimen preparation. GB / T 7124-2008 "Determination of Tensile Shear Strength of Adhesives" puts forward requirements for the preparation of tensile shear specimens of adhesives, requiring the bonding length to be 12.5 mm ± 0.25 mm, the total length after bonding to be 187.5 ± 0.25 mm, the two bonded specimens should be accurately aligned, and the adhesive layer thickness should be as uniform as possible. The typical adhesive layer thickness is 0.2 mm. GB / T7122-1996 "Determination of Peel Strength of High-Strength Adhesives - Floating Roller Method" puts forward requirements for the preparation of floating roller method peel specimens, requiring the length of the rigid adherend of the specimen to be 200 mm, the length of the flexible adherend to be 205 mm, one end to be aligned, and the preferred width to be 25 mm ± 0.5 mm.

[0003] The tensile shear strength and peel strength of adhesives are mandatory inspection items for adhesive performance. Generally, the number of specimens is required to be no less than 5. Due to differences in viscosity, filler particle size, etc. of different adhesives, the pressure required to control within a certain thickness range will be different. Therefore, different pre-pressures need to be applied according to the characteristics of the glue. In addition, before the glue cures, it has a certain fluidity, which may cause the movement of the specimen in the length direction and width direction, resulting in problems such as changes in the lap area, misalignment, and angular deformation. The existing patent CN217901333U discloses a preparation tooling for tensile shear strength specimens of adhesives, which is only applicable to the preparation of tensile shear specimens. The patent CN216525088U discloses a tooling for controlling the thickness of adhesive tensile shear specimen preparation, which is mainly used for adhesives cured by heating, and after completion, it needs to be cut according to the dimensions required by national or industry standards, and is only applicable to the preparation of tensile shear specimens. The patent CN116678705A discloses a method for preparing floating roller peel test specimens of adhesives. The adhesive layer thickness of the peel specimens prepared by the method is achieved by a C-type clamp, and is only applicable to the preparation of floating roller peel test specimens. The existing specimen preparation toolings can only produce tensile shear specimens or peel specimens, and multiple toolings need to be used when different standard specimens need to be prepared.

[0030] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings. However, the present utility model can be implemented in many different ways defined and covered by the following.

[0031] The following will be further described in detail with reference to the attached Figure 1-7 This application will be further described in detail.

[0032] The embodiment of this application discloses a sample preparation tool for tensile shear and stripping specimens.

[0033] Referring to Figure 1 , a sample preparation tool for tensile shear and stripping specimens 12 includes a bottom plate 1 and a tensile shear sample preparation assembly and a stripping sample preparation assembly provided on the bottom plate 1. The tensile shear sample preparation assembly is used to test the tensile shear strength of the adhesive 17, and the stripping sample preparation assembly is used to test the stripping strength of the adhesive 17. With one tool, tensile shear specimens 8 and stripping specimens 12 that meet different standards can be made at the same time, without the need for multiple devices, simplifying the sample preparation process.

[0034] Referring to Figure 2 , the tensile shear sample preparation assembly includes a first specimen groove 6 and a second specimen groove 7 provided on the bottom plate 1, and the first specimen groove 6 and the second specimen groove 7 are arranged along the first direction X. This design enables the two grooves to accurately align and fix the specimen, thereby ensuring that the tensile shear specimen 8 has a consistent size and adhesive layer thickness during the preparation process, improving the preparation accuracy of the specimen and the reliability of the test results

[0035] The stripping sample preparation assembly includes two guiding columns 10 arranged on the bottom plate 1. A plurality of pressing blocks 11 are slidably arranged between the two guiding columns 10 along the second direction Y. A test piece mounting groove 113 is arranged on the pressing block 11 along the third direction Z. The two guiding columns 10 in the stripping sample preparation assembly are arranged on the bottom plate 1, enabling the plurality of pressing blocks 11 to slide in the second direction Y, while the test piece mounting groove 113 on the pressing block 11 is arranged along the third direction Z. This design ensures that the stripping test piece 12 can be accurately positioned and uniform pressure can be applied during the preparation process, thereby ensuring that the size and thickness of the stripping test piece 12 are consistent, improving the accuracy of test piece preparation and the reliability of test results.

[0036] The first test piece groove 6 and the second test piece groove 7 are located between the two guiding columns 10. The pressing block 11 is located above the second test piece groove 7. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The first test piece groove 6 and the second test piece groove 7 are located between the two guiding columns 10, and the pressing block 11 is located above the second test piece groove 7. Through the design of being slidably arranged between the guiding columns 10 and the perpendicular arrangement of the three directions, when the pressing block 11 completes the production of the stripping test piece 12, it directly presses the tensile shear test piece 8 in the second test piece groove 7 by its own weight or an externally applied weight, without the need for other pressing components, thereby ensuring the accurate positioning and consistency of the test piece, and simplifying the operation process.

[0037] The tensile shear and stripping test piece 12 sample preparation tooling further includes a pressing component. The pressing component includes a cross beam 13 arranged on the guiding column 10. A pressing rod 14 for pressing the pressing block 11 is vertically connected to the cross beam 13. A counterweight is arranged at one end of the pressing rod 14 away from the cross beam 13. The function of the pressing component is to provide stable and adjustable pressure to ensure that the tensile shear test piece 8 and the stripping test piece 12 have consistent thickness and size during the production process. Its working principle is as follows: The pressing component includes a cross beam 13 fixed on the guiding column 10. A pressing rod 14 is vertically connected to the cross beam 13, and an adjustable counterweight is arranged at one end of the pressing rod 14 away from the cross beam 13. Under this pressure, the pressing block 11 uniformly presses the test piece in the test piece mounting groove 113, thereby ensuring that the test piece maintains the required thickness and size during the curing process, adapting to the requirements of different adhesives 17, and improving the preparation quality of the test piece and the reliability of test results.

[0038] The counterweight includes a tray 152 and a hook 151 connected to the tray 152. The tray 152 is used for stacking and placing weights 16. Through the counterweight 15 system composed of the tray 152 and the hook 151, the pressure applied to the test piece can be flexibly adjusted to ensure the consistency of the thickness and size of the test piece during the manufacturing process. The specific implementation method is that the tray 152 is connected to the distal end of the pressure bar 14 through the hook 151. Different weights of weights 16 can be stacked on the tray 152. By increasing or decreasing the quantity and weight of the weights 16, the pressure applied by the pressure bar 14 on the pressure block 11 is adjusted, so as to control the pressing force of the tensile shear test piece 8 and the peeling test piece 12, ensure that the test piece maintains a uniform thickness and precise size during the curing process, and meet the requirements of different adhesives 17.

[0039] Referring to Figure 6 and Figure 7 , a hook groove 142 for cooperating with the hook 151 is provided on the pressure bar 14, and a plurality of hook grooves 142 are uniformly spaced along the length direction of the pressure bar 14. Through the plurality of hook grooves 142 uniformly spaced along the length direction of the pressure bar 14, flexible adjustment position options are provided, enabling the counterweight 15 to be suspended at different height positions, thereby precisely adjusting the pressure applied to the test piece. The specific implementation method is that a plurality of hook grooves 142 are uniformly distributed on the pressure bar 14, and the tray 152 is hung on these hook grooves 142 through the hook 151. By selecting different positions of the hook grooves 142, the suspension height of the counterweight 15 can be changed, and further the pressure applied by the pressure bar 14 to the pressure block 11 can be adjusted. In this way, according to the requirements of different adhesives 17, the pressure can be flexibly adjusted to ensure the consistency of the thickness and size of the test piece, and improve the quality of test piece preparation and the reliability of test results.

[0040] A plurality of through holes 102 are provided on the guiding upright column 10 along the second direction Y, and the cross beam 13 is inserted and cooperated with the through holes 102. A plurality of through holes 102 are uniformly spaced along the second direction Y on the guiding upright column 10. By inserting the cross beam 13 into the through holes 102 at different heights, the height position of the cross beam 13 is adjusted, thereby changing the pressure applied by the pressure bar 14 and the counterweight 15 on the pressure block 11, enabling the pressure to be flexibly adjusted according to the requirements of different adhesives 17 during the sample preparation process, ensuring the consistency of the thickness and size of the test piece, and improving the quality of test piece preparation and the reliability of test results. A connection hole 141 is provided at the end of the pressure bar 14, and the cross beam 13 is passed through the connection hole 141.

[0041] On the bottom plate 1, there is a spacer 9 located between the first specimen groove 6 and the second specimen groove 7. The spacer 9 is used to support the specimen in the first specimen groove 6, so that the specimen in the first specimen groove 6 can maintain balance when lapping on the specimen in the second specimen groove 7. A spacer 9 with a height equivalent to the thickness of the specimen is arranged between the first specimen groove 6 and the second specimen groove 7 on the bottom plate 1. When the specimen in the first specimen groove 6 is placed on the spacer 9, the spacer 9 supports the height of the specimen, making it at the same level as the specimen in the second specimen groove 7 at the lap joint, thereby avoiding the specimen from tilting or uneven contact, ensuring a consistent adhesive layer thickness, and improving the bonding quality of the specimen and the reliability of the test results.

[0042] On the bottom plate 1, there are a third stop bar 4 and a fourth stop bar 5 perpendicular to the first specimen groove 6. The first specimen groove 6 and the second specimen groove 7 are located between the third stop bar 4 and the fourth stop bar 5. The third stop bar 4 and the fourth stop bar 5 are perpendicularly arranged on the bottom plate 1, and the first specimen groove 6 and the second specimen groove 7 are located between these two stop bars. When the specimen is placed in the groove, the third stop bar 4 and the fourth stop bar 5 limit the horizontal displacement of the specimen, ensuring that the specimen will not slide or shift during the preparation process, thereby guaranteeing the dimensional and positional accuracy of the specimen and improving the quality and consistency of specimen preparation.

[0043] Refer to Figure 3 and Figure 4 On both guiding columns 10, guiding ribs 101 are arranged along the second direction Y. Guide grooves 111 that are slidably matched with the guiding ribs 101 are provided at both ends of the pressing block 11. When the pressing block 11 slides between the guiding columns 10, the cooperation between the guiding ribs 101 and the guide grooves 111 ensures the smooth movement of the pressing block 11, prevents deviation or tilting, enables the pressing block 11 to accurately apply uniform pressure to the specimen, ensures the consistency of the specimen thickness and dimensions, and improves the quality of specimen preparation and the reliability of test results. Through the sliding cooperation between the guiding ribs 101 on the guiding columns 10 and the guide grooves 111 at both ends of the pressing block 11, it is ensured that the sliding process of the pressing block 11 in the second direction Y is stable and accurate, thereby applying uniform pressure.

[0044] On the bottom plate 1, there are multiple parallel first stop bars 2. The first specimen groove 6 is formed between adjacent first stop bars 2. On the bottom plate 1, there are multiple parallel second stop bars 3. The second specimen groove 7 is formed between adjacent second stop bars 3. The first stop bars 2 and the second stop bars 3 are distributed in the same direction in a one-to-one correspondence. When the specimen material is placed in these grooves, each groove can form an independent specimen position, ensuring that multiple specimens can be made simultaneously in the same operation, with consistent dimensions and thickness, and improving the sample preparation efficiency and the consistency of specimen quality.

[0045] The briquet 11 is provided with a protrusion 112 that matches the test piece installation groove 113. The protrusion 112 is used to press the test piece tightly within the test piece installation groove 113. A protrusion 112 that matches the size and shape of the test piece installation groove 113 is provided at the bottom of the briquet 11. When the briquet 11 is pressed down, the protrusion 112 is accurately pressed into the test piece installation groove 113, fixing and pressing the test piece within the installation groove. This can prevent the test piece from moving or deforming during the curing process, ensuring uniform thickness and precise position of the test piece.

[0046] Refer to Figure 1 、 Figure 3 and Figure 5, the working principle of this embodiment is as follows: First, the tensile shear test plate 1 81, tensile shear test plate 2 82, peel test plate 1 121, and peel test plate 2 122 to be bonded are polished and cleaned respectively to ensure that the surfaces are clean and pollution-free. Then, the tensile shear test plate 2 82 is placed in the second test piece groove 7 on the bottom plate 1, and it is aligned with the fourth retaining strip 5. And an adhesive 17 is evenly applied to the bonding area. Next, the tensile shear test plate 1 81 is placed in the first test piece groove 6, with one end of it fitting against the third retaining strip 4 and overlapping with the tensile shear test plate 2 82 in the second test piece groove 7 to ensure that the two test plates are bonded in parallel. At the same time, the spacer 9 between the first test piece groove 6 and the second test piece groove 7 on the bottom plate 1 is used to support the test piece in the first test piece groove 6 to keep it horizontal during overlapping and ensure that the bonded test piece is flat; after the placement of the tensile shear test piece 8 is completed, the pressing block 11 is installed. The pressing block 11 is placed above the second test piece groove 7. Through the cooperation of the guiding ribs on the guiding column 10 and the guiding grooves 111 at both ends of the pressing block 11, the pressing block 11 can slide stably. Then, the two polished and cleaned peel test plates 1 121 and peel test plates 2 122 are placed in the test piece installation groove 113 on the pressing block 11, and the adhesive 17 is evenly applied between the two peel test plates. After the peel test plates are placed, the next set of peel test plates is continued to be placed in the test piece installation groove 113 on the pressing block 11, and so on. Multiple pressing blocks 11 are stacked for production until all the peel test pieces 12 are made; a cross beam 13 is inserted into the through hole 102 on the guiding column 10. A pressing rod 14 is vertically connected to the cross beam 13. A counterweight 15 is provided at the distal end of the pressing rod 14. The counterweight 15 includes a tray 152 and a hook 151. According to the viscosity of the adhesive 17 and the required pressure, by adjusting the weight of the counterweight 15 and the position of the hook 151, or adjusting the height of the cross beam 13 in the through hole 102, an appropriate pressure is applied. Appropriate weights of weights 16 are stacked on the tray 152, and the quantity and specifications of the weights 16 are adjusted to achieve the required downward pressure, keeping the pressing block 11 applying a stable pressure to the test piece to ensure that the thickness of the adhesive 17 layer is consistent. Keep the device and the test piece in a static state until the glue layer is completely cured. For adhesives 17 that require heat curing, the entire device can be placed in a heating furnace for heat preservation and curing. After curing is completed, the counterweight 15 and the pressing assembly are removed, the pressing block 11 is carefully removed, and the cured tensile shear test piece 8 and peel test piece 12 are taken out. Check whether the size and thickness of the test piece meet the standard requirements to ensure that each test piece is uniform, and then perform performance testing.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
