Specific implementation mode
[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.
[0034] Next, according to the overall structure of the present invention, its embodiments will be described.
[0035] Embodiment 1:
[0036] A toughness drawing test device for processing polyamide heat insulation strips, as Figures 1-4 shown, includes a device main body 1, a groove 2 and a heat insulation strip 3. A displacement mechanism 4 is arranged inside the groove 2. The displacement mechanism 4 includes a lead screw motor 41, a lead screw 42 and a sliding seat 44. Slide rails 43 are arranged on both sides inside the groove 2. Support plates 5 are arranged on the top of the sliding seat 44 and the top of the device main body 1. A fixing mechanism 6 is arranged on the support plate 5; the fixing mechanism 6 includes a rectangular plate 61. An arc plate 62 and a cylindrical rod 63 are arranged on the rectangular plate 61. A U-shaped plate 69 is arranged on one side of the support plate 5. An electric push rod 65 is arranged on the other side of the support plate 5. A moving seat 66 is arranged at the output end of the electric push rod 65. A clamping plate 64 is arranged on one side of the moving seat 66. The arrangement of the displacement mechanism 4 enables the device main body 1 to effectively perform a drawing test on the heat insulation strip 3 to ensure the normal progress of the test. The arrangement of the fixing mechanism 6, especially the use of the arc plate 62 and the cylindrical rod 63, and the cooperation of the clamping plate 64 and the electric push rod 65. When the displacement mechanism 4 drives the heat insulation strip 3 to be continuously drawn to both sides, the heat insulation strip 3 is subjected to an outward pulling force, and the pressing force of the electric push rod 65 pushing the clamping plate 64 also faces outward. Coupled with the buffering of the friction force between the arc plate 62 and the cylindrical rod 63 and the heat insulation strip 3, compared with the way of directly pressing the heat insulation strip 3, it can provide a stable fixation for the heat insulation strip 3 and prevent it from slipping during the test.
[0037] Refer to Figure 1 、 Figure 2, the lead screw motor 41 is fixedly connected to the lead screw 42. The lead screw 42 is threadedly connected to the sliding seat 44, and the sliding seat 44 is slidably connected to the slide rail 43. When the lead screw motor 41 rotates, the lead screw 42 fixedly connected thereto rotates. With the assistance of the slide rail 43, the sliding seat 44 smoothly slides, ensuring the precise control and stability of the displacement mechanism 4, thereby providing smooth moving performance and achieving a stable pulling action during the test.
[0038] Refer to Figure 1 、 Figure 2 、 Figure 3 , there are two support plates 5. One of the support plates 5 is fixedly connected to the sliding seat 44, and the other support plate 5 is fixedly connected to the device main body 1. The setting of the two support plates 5 enhances the structural stability of the device and provides an effective supporting role for the fixing mechanism 6 during the pulling test. The two support plates 5 are respectively fixed on the sliding seat 44 and the device main body 1, ensuring that while one support plate 5 remains fixed, the other support plate 5 moves with the movement of the sliding seat 44, thus ensuring the normal progress of the pulling test.
[0039] Refer to Figure 3 、 Figure 4 , both the outer surfaces of the arc-shaped plate 62 and the cylindrical rod 63 are made of rubber material, and the interiors of the arc-shaped plate 62 and the cylindrical rod 63 are made of rigid material. The cylindrical rod 63 is arranged in an internally tangent manner with the extension line of the outer diameter of the arc-shaped plate 62. The rubber outer surfaces of the arc-shaped plate 62 and the cylindrical rod 63 provide a good friction coefficient, increasing the gripping force of the heat insulation strip 3 and assisting in reducing the risk of slipping. The internal rigid material makes the arc-shaped plate 62 and the cylindrical rod 63 have a certain durability and long-term stability. The special design of the extension line of the outer diameter of the cylindrical rod 63 and the arc-shaped plate 62 enables the heat insulation strip 3 to be smoothly wound around the outside of the cylindrical rod 63 and the arc-shaped plate 62 during winding and fixing, presenting a smooth transition at the unconnected part between the two.
[0040] Refer to Figure 3 、 Figure 4 , the electric push rod 65 is fixedly connected to both the support plate 5 and the moving seat 66. The moving seat 66 is fixedly connected to the clamping plate 64. When the electric push rod 65 is activated, the moving seat 66 fixedly connected thereto moves, causing the clamping plate 64 on one side of the moving seat 66 to move. The support plate 5 provides a good supporting role for the electric push rod 65. At the same time, the fixed connection of the electric push rod 65 to the support plate 5 and the moving seat 66 ensures the accurate transmission of the thrust, improving the test accuracy. The fixed connection of the moving seat 66 to the clamping plate 64 provides a stable platform, enabling the clamping plate 64 to reliably press the heat insulation strip 3.
[0041] Refer to Figure 3 、 Figure 4The upper end of the clamping plate 64 is matched with the cylindrical rod 63, and the lower end of the clamping plate 64 is matched with the arc plate 62. The good adaptability of the clamping plate 64, the cylindrical rod 63 and the arc plate 62 ensures the fixing effect of the thermal insulation strip 3 during the test and improves the accuracy of the test. At the same time, the adaptation design also helps to reduce the adjustment time, thereby improving the work efficiency to a certain extent.
[0042] Embodiment 2:
[0043] See also Figure 3 , Figure 4 A storage groove is provided on the U-shaped plate 69, and the card plate 64 is adapted to the storage groove. The storage groove on the U-shaped plate 69 provides a safe storage space for the card plate 64, which is convenient for avoiding hitting the card plate 64 during the process of winding the insulation strip 3, and helps to protect the card plate 64 and avoid accidental damage in a non-test state.
[0044] See also Figure 3 , Figure 4 An extension plate 67 is provided on the outer side of the movable seat 66, and a slide bar 68 is provided on the inner side of the U-shaped plate 69. The setting of the extension plate 67 and the slide bar 68 provides additional support and guidance to ensure the smooth movement of the card plate 64 when pressing the thermal insulation strip 3. In the process of the electric push rod 65 pushing the movable seat 66 and the card plate 64 to move, the force-bearing parts of the movable seat 66 and the card plate 64 are only in the middle. The extension plate 67 and the slide bar 68 can assist the movable seat 66 and the card plate 64 to maintain the stability of movement and pressing when the force is only in the middle.
[0045] See also Figure 3 , Figure 4 There are two groups of extension plates 67 and slide bars 68, and the two groups of extension plates 67 and slide bars 68 are symmetrically distributed. The two groups of symmetrical distribution of extension plates 67 and slide bars 68 provide balanced support and avoid tilting or offset caused by asymmetry. The auxiliary card plate 64 and the movable seat 66 can move more smoothly while ensuring the balance of the clamping force of the card plate 64. The symmetrical distribution design also helps to improve the neatness and aesthetics of the appearance of the device.
[0046] See also Figure 3 , Figure 4 The slide bar 68 is fixedly connected to the U-shaped plate 69, the extension plate 67 is fixedly connected to the movable seat 66, and the extension plate 67 is slidably connected to the slide bar 68. When the movable seat 66 is displaced as the electric push rod 65 is started, the extension plate 67 fixedly connected thereto is subjected to force and slides left and right on the slide bar 68. The fixed connection between the slide bar 68 and the U-shaped plate 69 can utilize the U-shaped plate 69 to provide a relatively stable support for the slide bar 68. The sliding connection between the extension plate 67 and the slide bar 68 allows the card plate 64 to be accurately adjusted when pressing the thermal insulation strip 3, thereby improving the flexibility of operation and the accuracy of the test.
[0047] The implementation principle of the present utility model is as follows: First, the heat insulation strip 3 to be tested is respectively wound around the outer sides of the arc-shaped plate 62 and the cylindrical rod 63 of the two-side fixing mechanism 6, and the electric push rod 65 is started, so that the electric push rod 65 pushes the moving seat 66 fixedly connected thereto towards the arc-shaped plate 62 and the cylindrical rod 63 until the clamping plate 64 on one side of the moving seat 66 completely presses and fixes the heat insulation strip 3 wound around the outer sides of the arc-shaped plate 62 and the cylindrical rod 63. Then, the lead screw motor 41 is started to drive the lead screw 42 to rotate. With the assistance of the slide rail 43, the sliding seat 44 drives the support plate 5 on its top to continuously move away from the other support plate 5 at the top of the device main body 1 to conduct a pulling test on the toughness of the fixed heat insulation strip 3, and record the test results according to the data displayed on the front side of the device main body 1. Finally, after the test is completed, the lead screw motor 41 is started again to drive the lead screw 42 to rotate in the reverse direction. With the assistance of the slide rail 43, the sliding seat 44 and the support plate 5 on its top move towards the other support plate 5 at the top of the device main body 1 until they are completely reset. Then, the electric push rod 65 is started to pull the moving seat 66 and the clamping plate 64 fixed on one side of the moving seat 66 back into the storage groove of the U-shaped plate 69, and the tested heat insulation strip 3 is taken off.
