Description

Technical Field

[0001] The present invention relates to the technical field of testing equipment, and in particular to a compressive performance testing device and method for testing new composite materials. Background Art

[0002] New materials refer to recently developed or currently developing structural materials with superior performance and functional materials with special properties. Structural materials, such as new ceramics and titanium alloys, primarily utilize their mechanical properties, such as strength, toughness, hardness, and elasticity. Functional materials, such as superconductors and optical fibers, primarily utilize their electrical, optical, acoustic, magnetic, and thermal functions and physical effects. Before entering the market, new materials must undergo compression testing to verify their compliance.

[0003] At present, existing compressive performance testing devices all rely on manual placement and installation of new materials, resulting in a low degree of automation in the compressive performance testing devices. Moreover, manual operation for a long time can easily lead to fatigue, which affects the accuracy of the test results, reduces functionality, and reduces practicality. In particular, when testing new materials, the new materials (if unqualified) sometimes break and splash outward, which can easily cause harm to the human body and reduce safety.

[0004] In order to solve the above problems, the present invention proposes a compressive performance testing device and method for testing new composite materials. Summary of the Invention

[0014] Furthermore, the second slide opening is slidably fitted with a slide block, and transmission grooves are provided on both sides of the upper end surface of the slide block. Both sides of the slide plate are slidably fitted inside the transmission grooves. One side of the slide block is fixedly connected to a fixed block, and both sides of the fixed block are fixed to the two side walls of the lower part of the accommodating cavity.

[0017] Furthermore, when the lifting plate and the placement member are in operation, one side surface of the sheet material contacts the upper end surface of the guide plate, and after the lifting plate and the placement member are in operation, the lower end surface of the sheet material is placed on the placement surface.

[0018] A method for testing the compressive performance of composite new materials, the specific method steps are as follows:

[0019] S1. Placement: Manually place the sheet material on the inner bottom of the placement groove, and stick one side of the sheet material to one side of the long board.

[0020] S2, conveying: Start the second hydraulic cylinder to drive the transmission plate to move to one side. The transmission plate is driven by force to drive the slide plate to slide to one side inside the transmission groove. The transmission plate also drives the placement member to move to one side. The placement member slides to one side on the slide block through the second slide opening. At the same time, the placement member drives the sheet material to be conveyed to one side.

[0021] S3, lifting: The transmission plate drives two long contact blocks to one side, and the guide surface gradually contacts the force-bearing surface of the lifting plate. Under the continued contact of the guide surface, the lifting plate gradually moves upward along the guide surface until the guide surface guides the lifting plate to the high surface. At the same time, the inclined surfaces of the two guide plates contact the two sides of the lower end surface of the sheet. At this time, the lifting plate is already on the high surface;

[0022] S4, Positioning: As the placement piece continues to move to one side, one side of the sheet material moves upward along the guide surface, which guides the sheet material onto the placement surface until one side of the sheet material contacts the two positioning plates and also contacts the contact sensor. At this time, the second hydraulic cylinder stops. After a pause of 5 seconds, the second hydraulic cylinder is restarted to drive the placement piece to move in the original direction. After the sheet material moves a certain distance in the original direction, the second hydraulic cylinder is stopped again.

[0023] S5. First detection: After the sheet is positioned, if the pressure resistance of the two sides of the sheet is to be detected, the motor 21 is started to drive the bidirectional screw to rotate clockwise. The bidirectional screw is forced to engage with the first pressing plate and the second pressing plate, so that the first pressing plate and the second pressing plate are pressed against the two sides of the sheet to detect the pressure resistance. The pressure resistance of the sheet is detected by the first pressure sensor and the second pressure sensor, thereby realizing the detection of the pressure resistance of the two sides of the sheet;

[0024] S6. Second detection: After the sheet is positioned, if the resistance to pressure on the upper surface of the sheet is detected, the first hydraulic cylinder is activated to drive the pressure rod to move downward. The pressure rod is forced to drive the pressing frame block to move downward. The pressing frame block gradually presses downward on the upper surface of the sheet, wherein the lower portion of the pressing frame block is inserted into the pressing groove. After the upper surface of the sheet is pressed, the middle of the sheet gradually bends downward. At the same time, the resistance to pressure is detected by the third pressure sensor, thereby realizing the detection of the resistance to pressure on the upper surface of the sheet;

[0025] S7. Return: Start the second hydraulic cylinder to move in the original direction. The sheet material is squeezed or pressed to cause the sheet material to bend upward or downward. The first or second abutment plate is used to make the sheet material separate from the two placement surfaces and move the sheet material to the inner bottom of the placement groove until the placement piece returns to its original position. Stop the second hydraulic cylinder.

[0026] Beneficial effects:

[0027] In the present invention, if the lengths of the two sides of the sheet are not uniform, one of the longer sides of the sheet will be pressed, so that one side of the sheet is forced to move to one side, until the first pressure plate and the second pressure plate are pressed against the sheet at the same time, so that the lengths of the two sides of the sheet are consistent, ensuring that the bending part of the sheet is located in the placement groove, effectively improving the detection accuracy of the sheet.

[0028] In the present invention, by providing the first groove and the second groove, there is enough space for the plate material to bend upward or downward, and the effect of plate material detection will not be affected.

[0029] In the present invention, by placing the covering of the groove, the plate pieces that are broken and splashed can be blocked, the safety of workers can be protected, and the safety can be improved.

[0030] In the present invention, through the pushing of the second push plate and the first push plate, no matter whether the middle of the sheet material is bent upward or downward, it can be pressed by the second push plate and the first push plate, pushing the bent sheet material back to the inner bottom of the placement groove, ensuring that the sheet material is smoothly sent back to its original position and can be easily removed manually.

[0031] In the present invention, the placement of the placement parts can make the sheet material placement work easy and simple, without the need for manual installation of the sheet material, and the feeding and returning of the material can also be realized, effectively enhancing the automation function. Moreover, manual operation of this work for a long time will not affect the accuracy of the detection results, thereby improving functionality and practicality.

[0032] In the present invention, the sheet material can be positioned by lifting the lifting plate, and the height of the sheet material is also lifted upward so that the sheet material is located in the middle of the placement groove. When testing the compressive resistance performance, the placement groove will not block the bending of the sheet material, thereby improving the accuracy of the compressive resistance test of the sheet material.

[0033] In the present invention, by arranging the pressing frame block and the pressing notch, not only the pressure resistance on both sides of the sheet material can be detected, but also the pressure resistance on the upper surface of the sheet material can be detected.

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1-10 The present invention is further described with examples:

[0047] A compressive performance testing device and method for testing new composite materials include a testing box 1, wherein a accommodating cavity 11 is provided inside the testing box 1; a fixed frame plate 12 is fixedly connected to the upper end surface of the testing box 1, and a first testing mechanism 2 is provided at the lower part of the fixed frame plate 12; a second testing structure 3 is provided on the upper end surface of the fixed frame plate 12; and a moving mechanism 4, a first lifting mechanism 5, and a second lifting mechanism 6 are provided at the bottom of the accommodating cavity 11.

[0048] In this embodiment, the first detection mechanism 2 includes a motor 21, which is fixedly connected to the upper part of one side of the detection box 1 through a support plate, and the output end of the motor 21 is connected to a bidirectional screw 22, and the two ends of the bidirectional screw 22 rotate in the rotation holes provided at the lower parts of both sides of the fixed frame plate 12, and one end of the bidirectional screw 22 is meshed with a first meshing hole 231 provided at the upper part of the first pressing plate 23, a first sliding hole 232 is provided at the upper part of the first pressing plate 23, and a first pressure sensor 24 is provided at the lower part of one side of the first pressing plate 23, and the first sliding hole 232 is provided in the first meshing hole 231. The first and second pressing plates 23 and 26 are both slidably fitted with a fixing rod 25, and both ends of the fixing rod 25 are fixed to the two side surfaces inside the fixed frame plate 12. One end of the bidirectional screw 22 is meshed with a second meshing hole 261 opened on the upper part of the second pressing plate 26. A second sliding hole 262 is opened on the upper part of the second pressing hole 26. The second sliding hole 262 is slidably fitted on the outer side of the fixing rod 25. A second pressure sensor 27 is provided at the lower part of one side of the second pressing plate 26. The first pressing plate 23 and the second pressing plate 26 are both slidably fitted with a sliding opening 111, which is opened in the middle of the upper end surface of the detection box 1. The motor 21 is started to drive the bidirectional screw 22 to rotate clockwise. The bidirectional screw 22 is forced to engage with the first pressing plate 23 and the second pressing plate 26, so that the first pressing plate 23 and the second pressing plate 26 slide in relative directions on the outside of the fixed rod 25. The first pressing plate 23 and the second pressing plate 26 slide in relative directions inside the sliding opening 111, effectively allowing the first pressing plate 23 and the second pressing plate 26 to move stably and smoothly. When the first pressing plate 23 and the second pressing plate 26 are squeezed relative to each other, if the lengths of the two sides of the sheet 13 are not aligned, the longer side of the sheet 13 will be pressed to make the sheet 13 3 is forced to move to one side until the first pressing plate 23 and the second pressing plate 26 simultaneously press against the sheet material 13, making the lengths of the two sides of the sheet material 13 consistent, ensuring that the bent portion of the sheet material 13 is located within the placement groove 461, effectively improving the detection accuracy of the sheet material 13. As the first pressing plate 23 and the second pressing plate 26 continue to squeeze, the pressure resistance of the sheet material 13 is tested. After the sheet material 13 is pressed, the middle portion of the sheet material 13 gradually bends. After the sheet material 13 gradually bends, the pressure resistance of the sheet material 13 is detected by the first pressure sensor 24 and the second pressure sensor 27. The provision of the first groove 462 and the second groove 463 ensures that there is sufficient space for the sheet material 13 to bend upward or downward, without affecting the detection effect of the sheet material 13.

[0049] In this embodiment, the second detection structure 3 includes a first hydraulic cylinder 31 fixedly connected to the middle of the upper end surface of the fixed frame plate 12, the output end of the first hydraulic cylinder 31 is connected to a pressure rod 32, the lower end of the pressure rod 32 is fixedly connected to a pressing frame block 33, and third sliding holes 331 are provided on both sides of the upper end surface of the pressing frame block 33. The insides of the two third sliding holes 331 are both slidably fitted with limit rods 34, and the lower end surfaces of the two limit rods 34 are fixed on both sides of the upper end surface of the detection box 1, and the lower end surface of the fixed frame plate 12 is provided with a third pressure sensor 35. The first hydraulic cylinder 31 is activated to drive the pressure rod 32 downward. The pressure rod 32 is then forced to move the pressing frame block 33 downward. The pressing frame block 33 slides downward through the third sliding hole 331 on the outside of the two limit rods 34, effectively ensuring the stable downward movement of the pressing frame block 33. As the pressing frame block 33 moves downward, it gradually presses downward against the upper surface of the sheet material 13. The lower portion of the pressing frame block 33 is inserted into the pressure notch 464. After the upper surface of the sheet material 13 is pressed, the middle portion of the sheet material 13 gradually bends downward. Simultaneously, the resistance pressure is detected by the third pressure sensor 35. The arrangement of the pressing frame block 33 and the pressure notch 464 allows detection of the resistance pressure not only on both sides of the sheet material 13 but also on the upper surface of the sheet material 13, thereby enhancing detection functionality.

[0050] In this embodiment, the moving mechanism 4 includes a fixed frame plate 41 fixedly connected to one side of the bottom of the accommodating chamber 11. A second hydraulic cylinder 42 is mounted on the upper end of the fixed frame plate 41. A push rod 43 is connected to the output end of the second hydraulic cylinder 42. One end of the push rod 43 is fixedly connected to a transmission plate 44. Slide plates 45 are fixedly connected to the upper ends of both sides of the transmission plate 44. A placement member 46 is fixedly connected to the upper ends of both slide plates 45. When the second hydraulic cylinder 42 is activated, the push rods 43 move sideways. The force exerted by the push rods 43 drives the transmission plate 44 sideways. The force exerted by the transmission plate 44 drives the slide plates 45 sideways within the transmission groove 471. The transmission plate 44 also drives the placement member 46 sideways. The placement member 46 slides sideways on the slide block 47 through the second slide opening 468. This facilitates easy and simple placement of the sheet material 13, eliminating the need for manual installation. Furthermore, prolonged manual operation does not affect the accuracy of the test results, thereby improving functionality and practicality.

[0051] In this embodiment, a placement groove 461 is provided on one side of the placement piece 46, a first groove 462 is provided on the lower end surface of the placement groove 461, and a second groove 463 is provided on the upper end surface of the placement groove 461, and a pressure groove opening 464 is provided on the top of the second groove 463. The first abutment plate 465 is fixedly connected to both sides of the upper part of one side of the placement piece 46, and the second abutment plate 466 is fixedly connected to both sides of the lower part of one side of the placement piece 46, and a long strip plate 467 is fixedly connected in the middle of the other side of the placement piece 46. A second slide opening 468 is provided on the lower end surface of the placement piece 46, and a sheet material 13 is placed at the bottom of the placement groove 461. After the sheet 13 is pressed, the middle part of the sheet 13 gradually bends. Through the setting of the first groove 462 and the second groove 463, there is enough space for the sheet 13 to bend upward or downward, and it will not affect the detection effect of the sheet 13. For example, when the sheet 13 breaks after bending, the covering of the placement groove 461 can block the broken and splashed sheet 13 pieces, protect the safety of workers, and improve safety. After the middle part of the sheet 13 bends upward or downward, it can be pressed by the second push plate 466 and the first push plate 465 to push the bent sheet 13 back to the inner bottom of the placement groove 461, ensuring that the sheet 13 is smoothly sent back to its original position and can be easily removed manually.

[0052] In this embodiment, the second slide opening 468 is slidably engaged with a slide block 47. Transmission grooves 471 are defined on both sides of the upper end surface of the slide block 47. The slide plate 45 slidably engages within the transmission grooves 471 on both sides. A fixing block 48 is fixedly connected to one side of the slide block 47. The fixing block 48 is fixed to the two side walls of the lower portion of the accommodating chamber 111 on both sides. An L-shaped fixing plate 49 is fixedly connected to the lower end surface of the other side of the slide block 47. One side of the L-shaped fixing plate 49 is fixed to the lower portion of one side of the detection box 1. This facilitates the delivery and return of materials, effectively enhancing automation.

[0053] In this embodiment, the first lifting mechanism 5 includes an elongated resistance block 51 fixedly connected to a side surface of the transmission plate 44, a high surface 511 is provided on the upper end surface of one side of the elongated resistance block 51, a guide surface 512 is provided in the middle of the upper end surface of the elongated resistance block 51, and a low surface 513 is provided on the upper end surface of the other side of the upper end surface of the elongated resistance block 51, and a moving block 52 is fixedly connected to the lower end surface of the elongated resistance block 51, and the moving block 52 is slidably engaged in a second slide groove 521, and the second slide groove 521 is opened on both sides of the bottom of the accommodating cavity 11. The transmission plate 44 drives the two elongated resistance blocks 51 to one side. The two elongated resistance blocks 51 are forced to slide to one side in the second slide groove 521 through the moving block 52. When the placement member 46 continues to move to one side, the guide surfaces 512 on the two elongated resistance blocks 51 gradually resist the force-bearing surface 531 on the lifting plate 53. Under the continued resistance of the guide surfaces 512, the lifting plate 53 can gradually move upward along the guide surfaces 512.

[0054] In this embodiment, the lower surface 513 abuts against the force-bearing surface 531 provided on the lower end surface of the lifting plate 53, and the upper end surface of the lifting plate 53 is provided with a placement surface 532, and a positioning plate 533 is fixedly connected to one side of the placement surface 532, and a friction sensor 54 is provided on one side of the positioning plate 533, and a guide plate 534 is fixedly connected to the other side of the placement surface 532. A limiting block 55 is provided on one side of the lifting plate 53, and two limiting blocks 55 are slidably fitted in the limiting groove 56. The two limiting grooves 56 are opened in the middle of the inner side surface of the accommodating cavity 11. The structural positions of the first lifting mechanism 5 and the second lifting mechanism 6 are the same. The lifting plate 53 slides upward in the second slide groove 521 through the two limit blocks 55, so that the lifting plate 53 moves upward stably until the guide surface 512 guides the lifting plate 53 to the high surface 511. At the same time, the inclined surfaces of the two guide plates 534 contact the two sides of the lower end surface of the sheet 13. At this time, the lifting plate 53 is already on the high surface 511 and stops moving upward. When the placement member 46 continues to move to one side, one side of the sheet 13 will move upward along the guide surface 512, and its guide surface 512 guides the sheet 13 to the placement surface 532. After the sheet 13 is on the placement surface 532, the sheet 13 is located in the middle of the inner part of the placement groove 461 until one side of the sheet 13 contacts the two positioning plates 533 and also presses against the contact sensor 54. The contact sensor 54 receives the pressure signal and stops the second hydraulic cylinder 42. It is beneficial to position the sheet material 13 and also to lift the height of the sheet material 13 upward so that the sheet material 13 is located in the middle of the placement groove 461. During the pressure resistance test, the placement groove 461 will not block the bending of the sheet material 13, thereby improving the accuracy of the pressure resistance test of the sheet material 13.

[0055] In this embodiment, when the lifting plate 53 and the placement member 46 are in operation, one side of the sheet material 13 contacts the upper end surface of the guide plate 534. After the lifting plate 53 and the placement member 46 are in operation, the lower end surface of the sheet material 13 is placed on the placement surface 532. This allows the sheet material 13 to be located in the middle of the placement groove 461.

[0056] A method for testing the compressive performance of composite new materials, the specific steps of the method are as follows:

[0057] S1. Placement: Manually place the sheet material 13 on the inner bottom of the placement groove 461, and stick one side of the sheet material 13 to one side of the long plate 467.

[0058] S2. Conveying: The second hydraulic cylinder 42 is activated to drive the transmission plate 44 to move to one side. The transmission plate 44 is driven by the force to drive the slide plate 45 to slide to one side inside the transmission groove 471. The transmission plate 44 also drives the placement member 46 to move to one side. The placement member 46 slides to one side on the slide block 47 through the second slide opening 468. At the same time, the placement member 46 drives the sheet material 13 to be transported to one side, which can easily and simply place the sheet material 13 without manual installation of the sheet material 13. The work of feeding and returning the material can also be realized, effectively enhancing the automation function.

[0059] S3. Lifting: The transmission plate 44 drives the two long abutment blocks 51 to one side, and the guide surface 512 gradually abuts against the force-bearing surface 531 on the lifting plate 53. Under the continued abutment of the guide surface 512, the lifting plate 53 gradually moves upward along the guide surface 512 until the guide surface 512 guides the lifting plate 53 to the high surface 511. At the same time, the inclined surfaces of the two guide plates 534 abut against both sides of the lower end surface of the sheet 13. At this time, the lifting plate 53 is already on the high surface 511, and the placement groove 461 will not block the bending of the sheet 13 during the pressure resistance test, thereby improving the accuracy of the pressure resistance test of the sheet 13.

[0060] S4. Positioning: As the placement member 46 continues to move to one side, one side of the sheet material 13 moves upward along the guide surface 512. The guide surface 512 guides the sheet material 13 to the placement surface 532 until one side of the sheet material 13 contacts the two positioning plates 533 and also contacts the contact sensor 54. At this time, the second hydraulic cylinder 42 is stopped. After a pause of 5 seconds, the second hydraulic cylinder 42 is restarted to drive the placement member 46 to move in the original direction. After the sheet material 13 moves a certain distance (between 5 cm and 10 cm) in the original direction, the second hydraulic cylinder 42 is stopped again to ensure that the sheet material 13 is located between the first pressing plate 23 and the second pressing plate 26.

[0061] S5. First detection: After the sheet 13 is positioned, if the pressure resistance of the two sides of the sheet 13 is detected, the motor 21 is started to drive the bidirectional screw 22 to rotate clockwise. The bidirectional screw 22 is forced to engage with the first pressing plate 23 and the second pressing plate 26, so that the first pressing plate 23 and the second pressing plate 26 are squeezed on both sides of the sheet 13 to detect the pressure resistance. The pressure resistance of the sheet 13 is detected by the first pressure sensor 24 and the second pressure sensor 27, thereby realizing the detection of the pressure resistance on both sides of the sheet 13, effectively ensuring that the bending part of the sheet 13 is located in the placement groove 461, and improving the detection accuracy of the sheet 13;

[0062] S6. Second detection: After the sheet 13 is positioned, when detecting the resistance of the upper surface of the sheet 13, the first hydraulic cylinder 31 is started to drive the pressure rod 32 to move downward. The pressure rod 32 is driven by the force to drive the pressing frame block 33 to move downward. The pressing frame block 33 gradually presses downward on the upper surface of the sheet 13, wherein the lower portion of the pressing frame block 33 is inserted into the pressure groove 464. After the upper surface of the sheet 13 is pressed by the force, the middle of the sheet 13 gradually bends downward. At the same time, the resistance is detected by the third pressure sensor 35, and then the resistance of the upper surface of the sheet 13 is detected, which is conducive to detecting not only the resistance of the two sides of the sheet 13, but also the resistance of the upper surface of the sheet 13.

[0063] S7. Return: Start the second hydraulic cylinder 42 to move in the original direction. The sheet material 13 is squeezed or pressed to cause the upward or downward bending phenomenon. The first abutment plate 465 or the second abutment plate 466 is used to make the sheet material 13 separate from the two placement surfaces 532, and move the sheet material 13 to the inner bottom of the placement groove 461 until the placement part 46 returns to the original position. Stop the second hydraulic cylinder. At this time, the bent sheet material 13 can be removed manually to ensure that the sheet material 13 is smoothly sent back to the original position and can be easily removed manually.

[0064] The specific working principle of the present invention includes the following process:

[0065] First, the sheet material 13 is manually placed on the inner bottom of the placement groove 461, and one side of the sheet material 13 is attached to the side surface of the long strip 467. Then, the second hydraulic cylinder 42 is started to drive the push rod 43 to move to one side. The push rod 43 is driven by the force to drive the transmission plate 44 to move to one side. The transmission plate 44 is driven by the force to drive the slide plate 45 to slide to one side inside the transmission groove 471. The transmission plate 44 also drives the placement member 46 to move to one side. The placement member 46 passes through the second slide opening 468 to one side. The plate 13 is moved to one side by the guide surface 512 of the lifting plate 53. The lifting plate 53 is moved to the side by the guide surface 512 of the lifting plate 53. The guide surface 512 gradually moves upward, wherein the lifting plate 53 slides upward on the second slide groove 521 through the two limit blocks 55, so that the lifting plate 53 moves upward stably until the guide surface 512 guides the lifting plate 53 to the high surface 511. At the same time, the inclined surfaces of the two guide plates 534 contact the two sides of the lower end surface of the sheet material 13. At this time, the lifting plate 53 has been on the high surface 511 and stops moving upward. When the placement member 46 continues to move to one side, one side of the sheet material 13 will move upward along the guide surface 512, and its guide surface 512 guides the sheet material 13 to the placement surface 532. After the sheet material 13 is on the placement surface 532, the sheet material 13 is located in the middle of the inner part of the placement groove 461 until one side of the sheet material 13 contacts the two positioning plates 533 and also presses against the contact sensor 54. The contact sensor 54 receives a pressure signal, which is transmitted to the controller. The controller receives the signal and stops the second hydraulic cylinder 42.

[0066] 5 seconds after the controller receives the signal, the second hydraulic cylinder 42 is started again to drive the placement piece 46 to move in the original direction. One side of the long strip 467 is away from one side of the sheet 13, and one side of the first abutment plate 465 is in contact with the other side of the sheet 13, so that the sheet 13 is away from one side of the two positioning plates 533. After the sheet 13 moves a certain distance (between 5cm and 10cm), the second hydraulic cylinder 42 is stopped again. At this time, the two side surfaces of the sheet 13 are located between the first pressure plate 23 and the second pressure plate 26. The motor 21 is started to drive the bidirectional screw 22 to rotate clockwise. The bidirectional screw 22 is forced to engage with the first pressure plate 23 and the second pressure plate 26, so that the first pressure plate 23 and the second pressure plate 26 slide in relative directions on the outside of the fixed rod 25, wherein the first pressure plate 23 and the second pressure plate 26 slide in relative directions inside the sliding opening 111, effectively allowing the first pressure plate 23 and the second pressure plate 26 to slide in relative directions on the inside of the sliding opening 111, effectively allowing the first pressure plate 23 and the second pressure plate 26 to slide in relative directions on the outside of the fixed rod 25, The plate 23 and the second pressure plate 26 move stably and smoothly. During the extrusion between the first pressure plate 23 and the second pressure plate 26, if the lengths of the two sides of the sheet 13 are not aligned, the longer side of the sheet 13 will be pressed, causing one side of the sheet 13 to be forced to move to one side until the first pressure plate 23 and the second pressure plate 26 press on the sheet 13 at the same time, making the lengths of the two sides of the sheet 13 consistent. As the first pressure plate 23 and the second pressure plate 26 continue to extrude, the pressure resistance of the sheet 13 is tested. After the sheet 13 is pressed, the middle part of the sheet 13 gradually bends in the first groove 462 or the second groove 463. After the sheet 13 gradually bends, the pressure resistance of the sheet 13 is detected by the first pressure sensor 24 and the second pressure sensor 27. If the sheet 13 breaks after bending, the covering of the placement groove 461 can prevent the broken and splashing sheet 13 pieces.

[0067] After inspecting the sheet material 13, the second hydraulic cylinder 42 is started to move in the original direction. Since the sheet material 13 is squeezed and bent upward in the middle, it will be abutted against one side of the sheet material 13 by the two first abutment plates 465. The two first abutment plates 465 are used to abut the sheet material 13 to separate from the two placement surfaces 532, and allow the sheet material 13 to move to the inner bottom of the placement groove 461. As the placement part 46 continues to move, it returns to its original position and the second hydraulic cylinder is stopped. At this time, the bent sheet material 13 can be removed manually, thereby completing the pressure resistance test of the two sides of the sheet material 13.

[0068] When continuing to detect the upper surface of the sheet material 13, the steps are the same as the above steps. The two side surfaces of the sheet material 13 are located between the first pressure plate 23 and the second pressure plate 26. This time, the first hydraulic cylinder 31 is started to drive the pressure rod 32 to move downward. The pressure rod 32 is driven by the force to drive the pressing frame block 33 to move downward. The pressing frame block 33 slides downward on the outside of the two limit rods 34 through the third sliding hole 331, effectively making the pressing frame block 33 move downward stably. As the pressing frame block 33 moves downward, it gradually presses downward on the upper surface of the sheet material 13. The lower part of the pressing frame block 33 is inserted into the pressing groove 464. After the upper surface of the sheet material 13 is pressed by force, the sheet material 13 The middle part gradually bends downward in the second groove 463. At the same time, the resistance pressure is detected by the third pressure sensor 35. After detecting the resistance pressure, the second hydraulic cylinder 42 moves to the original direction. Because the sheet material 13 is subjected to downward pressure, the middle part of the sheet material 13 bends downward and will be abutted by the two second abutment plates 466 on one side of the sheet material 13. The two second abutment plates 466 are used to abut the sheet material 13 to separate from the two placement surfaces 532 and move the sheet material 13 to the inner bottom of the placement groove 461. As the placement part 46 continues to move, it returns to its original position and stops the second hydraulic cylinder. At this time, the bent sheet material 13 can be removed manually, thereby completing the resistance pressure test of the upper surface of the sheet material 13.
