[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0033] like Figures 1 to 8 As shown, in order to facilitate accurate shear test and extrusion test of a plurality of mutually bonded polyurethane rigid foam boards 4, and to facilitate rapid placement of a plurality of mutually bonded polyurethane rigid foam boards 4 into a test device or rapid removal of the polyurethane rigid foam boards 4 from the test device, the utility model discloses a polyurethane rigid foam board mechanical testing device, which includes the following Figure 1 and Figure 2The polyurethane rigid foam board extrusion test device shown is used for the extrusion test of the polyurethane rigid foam board 4, and tests the extrusion performance of a plurality of polyurethane rigid foam boards 4 sequentially bonded to each other along the length direction. Figure 3 He Ru Figure 4 The polyurethane rigid foam board shear test device shown is used for shear resistance testing, and is used to test the shear resistance of a plurality of polyurethane rigid foam boards 4 bonded to each other in sequence along the width direction.
[0034] The polyurethane rigid foam board compression test device and the polyurethane rigid foam board shear test device both comprise a base plate 1 , a pressurizing mechanism, a blocking mechanism, and a limiting mechanism. The pressurizing mechanism, the blocking mechanism, and the limiting mechanism are all arranged on the base plate 1 .
[0035] by Figure 3 and Figure 4 Taking the polyurethane rigid foam board shear test device shown in the figure as an example, in this embodiment, the pressure mechanism and the blocking mechanism are arranged opposite to each other, and both the pressure mechanism and the blocking mechanism are arranged along the X-axis direction. The limiting mechanism includes relatively arranged limiting components, each of which is arranged along the Y-axis direction, and a first glue overflow groove 2 is provided on the limiting component. In other embodiments, each of the limiting components can also be arranged tilted to the Y-axis direction. Figure 3 As shown, a second glue overflow groove 3 is provided on the bottom plate 1 , and the first glue overflow groove 2 and the second glue overflow groove 3 are communicated with each other.
[0036] During the use of the polyurethane rigid foam board mechanical testing device of the present invention, several polyurethane rigid foam boards 4 to be tested, which are sequentially bonded to each other, are placed between the pressurizing mechanism and the blocking mechanism, with the bonding surface of each polyurethane rigid foam board 4 perpendicular to the pressurizing direction of the pressurizing mechanism. At the same time, several polyurethane rigid foam boards 4 to be tested, which are sequentially bonded to each other, are also placed between the respective relatively arranged limiting components. In this embodiment, Figure 3 and Figure 4 Taking the polyurethane rigid foam board shear test device shown as an example, after a number of polyurethane rigid foam boards 4 to be tested are sequentially bonded to each other and placed on the base plate 1, the four sides of the polyurethane rigid foam boards 4 are respectively limited by the pressure mechanism, the blocking mechanism and the limiting assembly. Each of the polyurethane rigid foam boards 4 is a number of columnar polyurethane rigid foam boards 4, and the side walls of each polyurethane rigid foam board 4 are sequentially bonded to each other, and the bonding seams between the polyurethane rigid foam boards 4 are arranged along the Y-axis direction. Figure 9As shown, the first glue overflow groove 2 and the second glue overflow groove 3 are both arranged toward the bonding seams between the polyurethane rigid foam boards 4. During use of the polyurethane rigid foam board shear test device, the pressurizing mechanism moves toward the blocking mechanism, and the polyurethane rigid foam boards 4 are squeezed in the X-axis direction. A small amount of glue bonding between the polyurethane rigid foam boards 4 is squeezed and overflows. The first glue overflow groove 2 and the second glue overflow groove 3 act as a clearance groove. Due to the arrangement of the first glue overflow groove 2 and the second glue overflow groove 3, a small amount of overflowed glue cannot contact the base plate 1 and the limiting assembly. At the same time, due to the arrangement of the limiting mechanism, during the squeezing process of the polyurethane rigid foam boards 4, the polyurethane rigid foam boards 4 are not easily deviated in the X-axis direction, thereby ensuring the accuracy of the test. In other embodiments, the bonding seams between the polyurethane rigid foam boards 4 can also be arranged tilted in the X-axis direction.
[0037] The utility model provides the first glue overflow groove 2 and the second glue overflow groove 3. When a number of the polyurethane rigid foam boards 4 bonded to each other in sequence are squeezed, the glue overflowing between the polyurethane rigid foam boards 4 is located in the first glue overflow groove 2 and the second glue overflow groove 3. Due to the yielding design of the first glue overflow groove 2 and the second glue overflow groove 3, the glue overflowing between the polyurethane rigid foam boards 4 will not come into contact with the polyurethane rigid foam board mechanical testing device, thereby not contaminating the polyurethane rigid foam board mechanical testing device, and facilitating the removal of the polyurethane rigid foam boards 4 after the test is completed.
[0038] In this embodiment, Figure 3 and Figure 10 As shown, Figure 3 and Figure 4 Taking the polyurethane rigid foam board shear test device shown as an example, the pressurizing mechanism includes a pressure sensor 5, a pressure push plate 6 connected to one end of the pressure sensor 5, and a pressure drive assembly connected to the other end of the pressure sensor 5, and the pressure push plate 6 is used to contact the polyurethane rigid foam board 4. During use of the polyurethane rigid foam board shear test device of the present invention, after a number of polyurethane rigid foam boards 4 bonded to each other in sequence are placed in place, the pressure drive assembly drives the push plate 6 to move toward the blocking mechanism to apply shear force to each of the polyurethane rigid foam boards 4. At this time, the pressure sensor 5 can display the specific value of the pressure applied by the pressure drive assembly. The utility model facilitates accurate acquisition of the force applied to each of the polyurethane rigid foam boards 4 by providing the pressure sensor 5. In other embodiments, the pressure sensor 5 may not be provided.
[0039] In this embodiment, Figure 1 and Figure 2Take the polyurethane rigid foam board extrusion test device shown as an example. The limiting assembly may include a first fixed plate 7 and a first limiting plate 8, the first fixed plate 7 and the bottom plate 1 are connected by bolts, and the first fixed plate 7 is arranged parallel to the bottom plate 1. The first fixed plate 7 and the first limiting plate 8 are welded and connected, and the first limiting plate 8 is arranged perpendicular to the bottom plate 1, that is, the first limiting plate 8 is arranged perpendicular to the first fixed plate 7. The first glue overflow groove 2 is arranged on the first limiting plate 8, and the first glue overflow groove 2 is arranged in a direction perpendicular to the bottom plate 1. At this time, as shown in FIG. Figure 5 Taking the polyurethane rigid foam board extrusion test device shown above as an example, the second glue overflow groove 3 is arranged along the X-axis, and its two ends are respectively connected to the first glue overflow groove 2 located on the first limiting plate 8. Furthermore, during use of the polyurethane rigid foam board extrusion test device, the height of the first limiting plate 8 is set to be greater than the height of the polyurethane rigid foam board 4. In this case, the polyurethane rigid foam board 4 can be effectively limited by the first limiting plate 8 in the X-axis direction.
[0040] In this embodiment, Figure 1 and Figure 2 Taking the polyurethane rigid foam board compression test device shown above as an example, since the plurality of sequentially bonded polyurethane rigid foam boards 4 are arranged sequentially along the Y-axis, the length of the plurality of sequentially bonded polyurethane rigid foam boards 4 in the Y-axis direction is relatively long. Therefore, at least two pairs of stopper assemblies are provided to ensure that the plurality of sequentially bonded polyurethane rigid foam boards 4 are not easily deviated in the X-axis direction during the compression process.
[0041] In this embodiment, the structure of the limit assembly can be Figure 1 and Figure 2 The structure of the limit assembly in the polyurethane rigid foam board extrusion test device shown in FIG. Figure 3 and Figure 4 The polyurethane rigid foam board shear test device shown in the figure is used as an example of the structure of the limit assembly. Figure 3 In, the limiting assembly includes a second fixing plate 9 and a second limiting plate 10, the second fixing plate 9 is bolted to the bottom plate 1, and the second fixing plate 9 is parallel to the bottom plate 1. The second fixing plate 9 includes a main plate 9a and an extension plate 9b connected to the main plate 9a, and the second fixing plate 9 is L-shaped. The second limiting plate 10 is welded to the main plate 9a, and the second limiting plate 10 is arranged perpendicular to the bottom plate 1, that is, the second limiting plate 10 is arranged perpendicular to the main plate 9a. The first glue overflow groove 2 is arranged on the second limiting plate 10, and the first glue overflow groove 2 is arranged in a direction perpendicular to the bottom plate 1. In Figure 3In the embodiment, the polyurethane rigid foam board mechanical testing device is used to clamp the polyurethane rigid foam board 4 where the joints between the polyurethane rigid foam boards 4 are arranged along the Y-axis direction, so the second glue overflow groove 3 is arranged along the Y-axis direction. At the same time, the polyurethane rigid foam board mechanical testing device is used to clamp a number of polyurethane rigid foam boards 4 that are bonded to each other in special shapes. Specifically, each polyurethane rigid foam board 4 is bonded in sequence along the width direction, and one end of the outermost polyurethane rigid foam board 4 has a protrusion 4a relative to other polyurethane rigid foam boards along the length direction of the polyurethane rigid foam board 4. The extension plate 9b is used to contact the protrusion 4a, and the second limiting plate 10 is used to contact the other polyurethane rigid foam boards 4 except the polyurethane rigid foam board 4 where the protrusion 4a is located. When Figure 1 During the use of the polyurethane rigid foam board mechanical testing device on the middle right, the shear force on the several polyurethane rigid foam boards 4 bonded to each other in sequence is along the X-axis direction, and due to the setting of the second limiting plate 10 and the extension plate 9b, the several polyurethane rigid foam boards 4 bonded to each other in sequence are effectively prevented from deviating in the Y-axis direction.
[0042] In this embodiment, Figure 1 and Figure 2 Take the polyurethane rigid foam board extrusion test device shown as an example. The blocking mechanism includes a third fixed plate 11 and a blocking plate 12. The third fixed plate 11 is bolted to the base plate 1, and the third fixed plate 11 is arranged parallel to the base plate 1. The blocking plate 12 is welded to the third fixed plate 11, and the blocking plate 12 is arranged perpendicular to the base plate 1, that is, the blocking plate 12 is arranged perpendicular to the third fixed plate 11. The blocking plate 12 is used to support a number of polyurethane rigid foam boards 4 that are bonded to each other in sequence. Similar to the first limiting plate 8, during use of the polyurethane rigid foam board extrusion test device, the height of the blocking plate 12 is also set to be greater than the height of the polyurethane rigid foam board 4. At this time, the polyurethane rigid foam board 4 can be well restricted by the blocking plate 12 in the Y-axis direction. In other embodiments, the third fixed plate 11 can also be arranged to be inclined relative to the base plate 1.
[0043] In this embodiment, Figure 3 and Figure 4 The structure of the blocking mechanism in the polyurethane rigid foam board shear test device is as follows: Figure 1 and Figure 2The blocking mechanism structure of the polyurethane rigid foam board compression test device is exactly the same as that of the polyurethane rigid foam board shear test device. The difference between the two is that in the polyurethane rigid foam board shear test device, the polyurethane rigid foam boards 4 that are sequentially bonded to each other are longer in the Y-axis direction. In order to effectively block the polyurethane rigid foam boards 4, the blocking mechanism in the polyurethane rigid foam board shear test device is provided with at least two.
[0044] In this embodiment, Figure 1 and Figure 3 As shown in FIG, the pressure drive assembly in the polyurethane rigid foam board extrusion test device is identical to the pressure drive assembly in the polyurethane rigid foam board shear test device. Figure 3 Taking the polyurethane rigid foam board shear test device shown in as an example, the pressure drive assembly includes a pressure device and a locking part, and the pressure device can be a cylinder. The locking part includes a locking fixing plate 13, a push rod 14 and locking nuts 15 arranged in pairs. The locking fixing plate 13 is arranged on the base plate 1, and a through hole is provided on the locking fixing plate 13. The push rod 14 passes through the through hole. One end of the push rod 14 is connected to the pressure sensor 5, and the other end of the push rod 14 is connected to the pressure device. The push rod 14 is provided with a thread, and the locking nut 15 cooperates with the thread, and the locking nuts 15 arranged in pairs are located on both sides of the locking fixing plate 13. During use of the polyurethane rigid foam board mechanical testing device of the present invention, it is necessary to maintain pressure on each polyurethane rigid foam board 4 for several hours. Therefore, when the pressure device applies pressure to the push rod 14, and thus gradually applies pressure to each polyurethane rigid foam board 4, the pressure value of the pressure device on the polyurethane rigid foam board 4 at this time can be determined by observing the value on the pressure sensor. When the target pressure value is reached, each locking nut 15 is rotated toward the fixed plate 13 to lock it. After each locking nut 15 is completely locked, the pressure device can be removed. The provision of the locking portion in the present invention can maintain pressure on each polyurethane rigid foam board 4, thereby allowing the pressure device to be removed and reducing energy consumption.
[0045] In this embodiment, Figure 9 As shown, the cross section of the first glue overflow groove 2 is semicircular, and the diameter of the first glue overflow groove 2 is 8 to 12 mm. Figure 7 As shown, taking the second overflow glue groove 3 in the polyurethane rigid foam board shear test device as an example, the second overflow glue groove 3 can be a through hole, and the length of the second overflow glue groove 3 along the X-axis direction is also 8 to 12 mm. In other embodiments, the first overflow glue groove 2 can also be as shown in FIG. Figure 7 The second glue overflow groove 3 also uses a through hole.
[0046] In summary, the polyurethane rigid foam board mechanical testing device of the present invention utilizes the first and second overflow glue grooves 2 and 3. When a plurality of sequentially bonded polyurethane rigid foam boards 4 are squeezed, the glue overflowing between the boards 4 is located within the first and second overflow glue grooves 2 and 3. Due to the design of the first and second overflow glue grooves 2 and 3, the overflowing glue between the boards 4 does not come into contact with the testing device, thereby preventing contamination. This facilitates removal of the boards 4 after the test is completed. Furthermore, the pressure sensor 5 facilitates accurate measurement of the force applied to each board 4. Furthermore, the locking portion maintains pressure on each board 4, allowing the pressurizing device to be removed, reducing energy consumption.
[0047] It should be emphasized that the above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
