Description

Technical Field

[0001] This utility model relates to the field of cemented carbide plate technology, specifically a cemented carbide plate impact resistance testing platform. Background Technology

[0002] Hard alloys possess a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. In particular, their high hardness and wear resistance remain essentially unchanged even at 500℃, and they still have very high hardness at 1000℃.

[0003] A search revealed a Chinese patent (CN221280792U) disclosing a hard alloy plate impact resistance testing platform, including a placement box. This device, through an adjustment mechanism, allows pulling a ring to slide a conical block within a fixed frame. When the conical block is pulled out from the inner wall of the conical groove, an L-shaped plate slides within a groove on a mating plate. After the mating plate is slid to the desired position, releasing the ring causes the conical block, under the elastic force of a compression spring, to embed into the inner wall of the corresponding conical groove on the mating plate. This completes the fixing of the arc-shaped slider after position adjustment, further enabling adjustment of the height of the tested object. This facilitates impact resistance testing of objects at different heights, achieving the testing objective.

[0004] While the above solutions are applicable to impact testing of heavy objects at different heights, the aforementioned patents are difficult to adjust the position of the heavy object being tested, and can only perform impact testing on a single location of the alloy plate, which is quite limited and greatly reduces the practical effect. Therefore, we provide a hard alloy plate impact testing platform to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a technical solution for a cemented carbide plate impact resistance testing platform.

[0025] Please see Figure 1 , Figure 2 and Figure 5 The device includes a placement box 1 and a winding mechanism 7. The top of the placement box 1 is rotatably connected to a clamping swing plate 20. The purpose of setting the clamping swing plate 20 is to allow the position of the wing bolt 21 to be freely changed through its movable design, which is beneficial for the subsequent placement of the alloy plate. The clamping swing plate 20 is threadedly connected to the wing bolt 21. The purpose of setting the wing bolt 21 is to allow the height of the wing bolt 21 to be changed by rotating through its threaded design. One end of the wing bolt 21 is fixedly connected to a washer 22. The washer 22 can effectively press the alloy plate, thereby ensuring the stability of the alloy plate.

[0026] Please see Figure 2 and Figure 3The bottom of the winding mechanism 7 is fixedly connected to an auxiliary rail 11. The purpose of setting the auxiliary rail 11 is to effectively control the circular detection weight 10, ensure the stability of the detection weight 10, and allow the detection weight 10 to fall straight down, preventing the detection weight 10 from deviating during the fall.

[0027] Please see Figure 2 and Figure 4 A U-shaped mounting bracket 14 is fixedly connected to one side of the auxiliary track 11. The U-shaped mounting bracket 14 can effectively control the positioning pin 18, allowing the positioning pin 18 to move more smoothly. A control housing 15 is fixedly connected to one side of the U-shaped mounting bracket 14. A guide rod 16 is slidably connected to the inner wall of the control housing 15. The control housing 15 can effectively control the guide rod 16, thereby ensuring the stability of the guide rod 16.

[0028] Please see Figure 4 The other end of the guide rod 16 is fixedly connected to a positioning pin 18. The guide rod 16 and the positioning pin 18 are integrated into one unit and maintain a linkage effect. The positioning pin 18 can effectively restrict the limiting plate 13, thereby ensuring the stability of the limiting plate 13 and thus ensuring the stability of the control baffle 12.

[0029] Please see Figure 4 A tough spring 19 is fixedly connected to one side of the positioning pin 18. The tough spring 19 is sleeved on the outer circumferential surface of the guide rod 16. The purpose of setting the tough spring 19 is to effectively apply force to the positioning pin 18 by utilizing the rebound characteristics of the tough spring 19 itself, so that the positioning pin 18 can be reset, thereby enabling the positioning pin 18 to successfully complete the blocking of the limiting plate 13.

[0030] Please see Figure 3 and Figure 4 One end of the guide rod 16 is fixedly connected to an external pull ring 17. The purpose of setting the external pull ring 17 is to facilitate the manual pulling of the guide rod 16 by the staff. The inner wall of the auxiliary track 11 is slidably connected to a control baffle 12. The setting of the control baffle 12 can effectively control the position of the detection weight 10, so that the detection weight 10 is at the expected height, thereby enhancing the practical effect.

[0031] Please see Figure 3 One side of the control baffle 12 is fixedly connected to one side of the limiting plate 13. The control baffle 12 and the limiting plate 13 are integrated and maintain a linkage effect. The limiting plate 13 has a pin hole. The drum of the winding mechanism 7 is fixedly connected to the wire rope 9. The winding mechanism 7 is mainly used to wind up and unwind the wire rope 9. The winding mechanism 7 consists of a shell, a drum and a power source that drives the drum to rotate.

[0032] Please see Figure 1 and Figure 3 One end of the steel wire rope 9 is fixedly connected to the test weight 10. The purpose of setting the test weight 10 is to use the impact force generated by the natural fall of the test weight 10 to test the impact resistance of the alloy plate. The top of the placement box 1 is fixedly connected to the L-shaped support frame 2. The L-shaped support frame 2 is mainly used to support the DC motor 3, the guide shell 8 and other components.

[0033] Please see Figure 1 A DC motor 3 is fixedly connected to one side of the L-shaped support frame 2. The output shaft of the DC motor 3 is fixedly connected to the power swing arm 4. The purpose of setting the DC motor 3 is to effectively provide sufficient power support for the movement of the power swing arm 4. The DC motor 3 is a known technology and will not be described in detail in this application.

[0034] Please see Figure 1 and Figure 2 One end of the power swing arm 4 is rotatably connected to the force-applying plate 5. The force-applying plate 5 is rotatably connected to the winding mechanism 7 through the positioning shaft 6. The cooperation between the power swing arm 4, the force-applying plate 5 and the positioning shaft 6 can effectively change the position of the winding mechanism 7, thereby changing the position of the detection weight 10. The winding mechanism 7 is slidably connected to the inner wall of the guide housing 8. The guide housing 8 will exert a control effect on the winding mechanism 7, so that the winding mechanism 7 can only move horizontally within the guide housing 8. The guide housing 8 is fixedly connected to the L-shaped support frame 2.

[0035] Working principle: In use, the alloy plate is placed in the placement box 1. The clamping swing plate 20 is rotated so that the pad 22 is above the alloy plate. Then, the butterfly bolt 21 is manually rotated so that the pad 22 contacts the alloy plate and applies pressure, thus ensuring the stability of the alloy plate. Then, the winding mechanism 7 releases the winding force on the wire rope 9. Under the action of the weight of the test weight 10, the wire rope 9 will move. At this time, the test weight 10 will fall straight down along the auxiliary track 11, thus impacting the alloy plate and achieving the effect of testing the impact resistance of the alloy plate. To test the impact force brought by the test weight 10 falling from different heights, simply pull the external pull ring 17 manually. This will drive the positioning pin 18 to move through the guide rod 16, so that the positioning pin 18 releases the restriction on the limiting plate 13. When the limiting plate 13 is moved downwards... The position of the control baffle 12 can be changed by moving it. When the detection weight 10 rises due to the winding of the wire rope 9, the detection weight 10 will hit the control baffle 12 and stop, thereby adjusting the highest position of the detection weight 10. This achieves the effect of impact testing of the alloy plate by the detection weight 10 falling from different heights. Finally, when it is necessary to perform impact testing on different positions of the alloy plate, the DC motor 3 is started to work, driving the power swing arm 4 to move. At this time, because the positioning shaft 6, which is combined with the force application plate 5, is restricted by the guide shell 8 through the winding mechanism 7, the power swing arm 4 can drive the positioning shaft 6 to move through the force application plate 5, thereby changing the position of the winding mechanism 7 in the guide shell 8, thereby changing the position of the detection weight 10, auxiliary track 11 and other components, and achieving the purpose of adjusting the position of the detection weight 10.
