Description

Technical Field

[0001] This utility model relates to the field of impact testing machine technology, specifically an impact testing machine for testing fiber-reinforced nylon sheets. Background Technology

[0002] Fiber-reinforced nylon sheet is a high-performance engineering plastic sheet made of nylon as the matrix and reinforced with a certain proportion of glass fiber. During the production process, cantilever beam impact testing machines are often used to test the samples of fiber-reinforced nylon sheets to determine their impact resistance.

[0003] Patent CN222825406U discloses a cantilever beam impact testing machine. This machine includes a base, a cantilever beam body fixedly connected to the base, an electric push rod on the cantilever beam body, and an impact head at the output end of the push rod. A positioning mechanism for limiting the test specimen is located above the base. This positioning mechanism includes a positioning seat fixedly connected to the base, with a clamping assembly and an impact positioning assembly on the seat. Through this positioning mechanism design, the cantilever beam impact testing machine first adjusts the position of the impact positioning assembly to quickly engage and position the test specimen at the impact width. Then, the clamping assembly clamps and positions the test specimen, allowing for rapid toughness testing. This facilitates rapid specimen positioning during repeated tests, saving time and effort in the operation.

[0004] However, the aforementioned cantilever beam impact testing machine still has the following problems in actual use: During cantilever beam impact testing, the equipment uses a pendulum that rotates and falls instantaneously to strike the specimen and obtain corresponding impact performance data. However, due to inertia, the pendulum continues to swing back and forth for a period of time after the impact. During this period, the testers must wait until it comes to a complete stop before they can safely remove the specimen, which prolongs the testing cycle and reduces the overall testing efficiency.

[0005] Currently, although some operators may manually intervene in the pendulum's movement path to force it to stop in order to save waiting time, this operation is highly risky and can easily cause injury, posing a serious safety hazard. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides an impact testing machine for testing fiber-reinforced nylon sheets, which can assist the pendulum rod in stopping quickly.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an impact testing machine for testing fiber-reinforced nylon sheets, comprising a base plate, a clamp mounted on the base plate, a vertical plate, an operating screen mounted on the upper part of the vertical plate, a swing arm, and an impact block located at the lower end of the swing arm. A support plate is fixedly connected to the side of the vertical plate near the operating screen, and a rotating mechanism is connected to the other end of the support plate. A monitoring mechanism is connected to the output end of the rotating mechanism, and a movable component is connected to the other end of the monitoring mechanism. A second magnet is connected inside the movable component. A connecting block is fixedly connected to the lower end of the swing arm, and a first magnet is fixedly connected to the inner wall of the connecting block. The bottom surface of the connecting block is connected to the upper end of the impact block, and the first magnet and the second magnet repel each other.

[0008] Furthermore, the rotating mechanism includes a rotating motor and a rotating rod. The outer wall of the rotating motor is fixedly connected to the end of the support plate away from the vertical plate. The output shaft of the rotating motor is fixedly connected to one end of the rotating rod, and the other end of the rotating rod is connected to the monitoring mechanism.

[0009] Furthermore, the monitoring mechanism includes a rotating plate and a monitoring sensor. One end of the rotating plate is fitted and fixedly connected to the outer wall of the rotating rod, and the other end of the rotating plate is connected to the movable component. The side of the rotating plate near the clamp is fixedly connected to the monitoring sensor, and the monitoring end of the monitoring sensor faces the clamp.

[0010] Furthermore, the movable component includes a buffer plate and a spring. The outer wall of one end of the buffer plate is fixedly connected to the end of the rotating plate away from the rotating rod. A movable opening is provided through the upper surface of the buffer plate. One end of the spring is fixedly connected to the inner wall of the movable opening. The other end of the spring is fixedly connected to the side of the second magnet away from the first magnet. The second magnet is slidably connected to the movable opening.

[0011] Furthermore, a guide rod is fixedly connected to one end of the second magnet near the spring, and the other end of the guide rod passes through the movable port and is slidably connected to the movable port.

[0012] Furthermore, a cushioning pad is fixedly connected to the side of magnet number two that is closer to magnet number one.

[0013] Furthermore, a rotating shaft is fixedly connected to the end of the support plate away from the upright plate. An auxiliary plate is fitted and rotatably connected to the outer wall of the rotating shaft. The other end of the auxiliary plate is fixedly connected to the end of the buffer plate away from the rotating plate. The rotating shaft is located on the side of the support plate away from the rotating motor.

[0014] Furthermore, the connecting block and the impact block are detachably connected by bolts.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This impact testing machine for testing fiber-reinforced nylon sheets utilizes the repulsive properties of magnet number one and magnet number two to provide additional reverse thrust when the pendulum swings in the opposite direction. Combined with the rigid blocking of the moving components, the next operation can be performed without waiting for the pendulum to come to a natural stop, which greatly shortens the testing cycle. This impact testing machine for testing fiber-reinforced nylon sheets uses an automated monitoring and braking mechanism to avoid manual intervention in the movement path of the pendulum, fundamentally solving the risk of personnel injury that may be caused by manual forced stopping and improving the safety of equipment use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-4 An impact testing machine for testing fiber-reinforced nylon sheets includes a base plate 1, a clamp 2 mounted on the base plate 1, a vertical plate 20, an operating screen 3 mounted on the upper end of the vertical plate 20, a swing arm 11, and an impact block 4 located at the lower end of the swing arm 11. A support plate 8 is fixedly connected to the side of the vertical plate 20 near the operating screen 3. A rotating mechanism is connected to the other end of the support plate 8. A monitoring mechanism is connected to the output end of the rotating mechanism. A movable component is connected to the other end of the monitoring mechanism. A second magnet 16 is connected inside the movable component. A connecting block 5 is fixedly connected to the lower end of the swing arm 11. A first magnet 12 is fixedly connected to the inner wall of the connecting block 5. The bottom surface of the connecting block 5 is connected to the upper end of the impact block 4. The first magnet 12 and the second magnet 16 repel each other.

[0020] like Figures 1 to 4 As shown, when using the impact testing machine for testing fiber-reinforced nylon sheets in this utility model, the relevant test program is first set through the operation screen 3. Then, the fiber-reinforced nylon sheet sample to be tested is clamped by the clamp 2. After that, the test is started. Before the test, the impact block 4 at the front end of the swing arm 11 is located at the upper right of the upright plate 20 (between the upright plate 20 and the operation screen 3) through the limiting component. During the test, the limiting component is automatically released. Then, the swing arm 11, the connecting block 5, the first magnet 12 and the impact block 4 rotate by themselves due to gravity. When the impact block 4 rotates to the position of the clamp 2, the impact block 4 contacts the sample and impacts it. Then the sample is broken, and the corresponding test data can be obtained. At the same time that the impact block 4 comes into contact with the sample, the monitoring mechanism detects that the pendulum 11 has passed by. At this time, the monitoring mechanism transmits the data to the processor inside the operation screen 3. Then the controller inside the operation screen 3 automatically starts the rotation mechanism (power on). When the data is obtained, the pendulum 11 and the impact block 4 will swing in opposite directions due to inertia. At this time, the pendulum 11 passes by the monitoring mechanism again. After the monitoring mechanism transmits the electrical signal to the operation panel 3, the rotating mechanism is officially started and rotates together with the monitoring mechanism and moving components towards the clamp 2 (originally these components were parallel to the upright plate 20 and would not obstruct the normal swing of the swing arm 11 and other components). When it stops after rotating 90°, the swing arm 11 will swing again due to inertia. Because the first magnet 12 inside the connecting block 5 of the swing arm 11 and the second magnet 16 inside the movable component repel each other, an additional reverse thrust can be given to the swing arm 11 to accelerate the stopping of the swing arm 11. At the same time, the movable component rigidly blocks the continued rotation of the swing arm 11, so that the swing arm 11 can be stopped quickly without external force. It should be noted that the base plate 1, clamp 2, upright plate 20, operation screen 3, swing rod 11, impact block 4, and limiting components mentioned above are all mature technologies in existing cantilever beam impact testing machines. Therefore, the positional relationship, connection relationship, and working principle of each component will not be described in detail here. It should also be noted that in this utility model, only the structure of the disclosed patent is partially improved. Other structures mentioned in the disclosed patent but not improved, such as clamp 2 and operation screen 3, are not modified in any way and retain their original functions and effects.

[0021] As a preferred embodiment of this utility model, the rotating mechanism includes a rotating motor 9 and a rotating rod 13. The outer wall of the rotating motor 9 is fixedly connected to the end of the support plate 8 away from the vertical plate 20. The output shaft of the rotating motor 9 is fixedly connected to one end of the rotating rod 13, and the other end of the rotating rod 13 is connected to the monitoring mechanism.

[0022] More specifically, when it is necessary to control the rotation of components such as the monitoring mechanism and moving parts, the operation panel 3 will start the rotation motor 9. The output shaft of the rotation motor 9 will rotate the rotating rod 13, which in turn will rotate the monitoring mechanism and moving parts connected to the rotating rod 13.

[0023] As a preferred embodiment of the present invention, the monitoring mechanism includes a rotating plate 6 and a monitoring sensor 19. One end of the rotating plate 6 is sleeved and fixedly connected to the outer wall of the rotating rod 13, and the other end of the rotating plate 6 is connected to the movable component. The side of the rotating plate 6 near the clamp 2 is fixedly connected to the monitoring sensor 19, and the monitoring end of the monitoring sensor 19 faces the clamp 2.

[0024] More specifically, when the rotating motor 9 is not started, the monitoring end of the monitoring sensor 19 is facing forward (towards the operation screen 3). When the swing arm 11 rotates past the front of the monitoring sensor 19, the monitoring sensor 19 obtains the corresponding data, which can then be transmitted to the operation screen 3 in a timely manner to start the rotating motor 9. It should be noted that the monitoring sensor 19 can be a photoelectric sensor, proximity sensor or magnetic sensor, or other sensors with equivalent functions that can detect the movement of the pendulum 11 without contact.

[0025] As a preferred embodiment of this utility model, the movable component includes a buffer plate 7 and a spring 18. The outer wall of one end of the buffer plate 7 is fixedly connected to the end of the rotating plate 6 away from the rotating rod 13. A movable opening 701 is provided through the upper surface of the buffer plate 7. One end of the spring 18 is fixedly connected to the inner wall of the movable opening 701. The other end of the spring 18 is fixedly connected to the side of the second magnet 16 away from the first magnet 12. The second magnet 16 is slidably connected to the movable opening 701.

[0026] More specifically, when the rotating motor 9 rotates downwards with the rotating plate 6 and the monitoring sensor 19, the buffer plate 7 and the spring 18 connected to the rotating plate 6 rotate together, thereby rotating the second magnet 16 located in the moving port 701 onto the path of the first magnet 12. As the first magnet 12 approaches, the repulsion between the two magnets can quickly decelerate the swing arm 11. Even if the inertial connecting block 5 is still in contact with the second magnet 16, the second magnet 16 can also yield under the action of the spring 18, reducing the hard impact force.

[0027] As a preferred embodiment of this utility model, a guide rod 17 is fixedly connected to one end of the second magnet 16 near the spring 18, and the other end of the guide rod 17 passes through the moving port 701 and is slidably connected to the moving port 701.

[0028] More specifically, by setting the guide rod 17, the movement trajectory of the second magnet 16 can be restricted.

[0029] As a preferred embodiment of this utility model, a cushioning pad 15 is fixedly connected to the side of the second magnet 16 near the first magnet 12.

[0030] More specifically, by setting up the cushioning pad 15, the impact force between the second magnet 16 and the connecting block 5 can be further reduced.

[0031] As a preferred embodiment of this utility model, a rotating shaft 14 is fixedly connected to one end of the support plate 8 away from the upright plate 20. An auxiliary plate 10 is sleeved on the outer wall of the rotating shaft 14 and rotatably connected to it. The other end of the auxiliary plate 10 is fixedly connected to the end of the buffer plate 7 away from the rotating plate 6. The rotating shaft 14 is located on the side of the support plate 8 away from the rotating motor 9.

[0032] More specifically, by setting up the rotating shaft 14 and the auxiliary plate 10, the impact force of the buffer plate 7 can be improved when the connecting block 5 and the second magnet 16 come into contact and collide, while also sharing the impact force of the rotating rod 13 and the rotating motor 9.

[0033] As a preferred embodiment of this utility model, the connecting block 5 and the impact block 4 are detachably connected by bolts.

[0034] More specifically, the impact block 4 can be separated and replaced with other types of impact blocks 4 according to the test requirements through bolt connection.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
