[0002] Plasticity is a crucial material property for tungsten alloys. By combining pressure processing and different heat treatment processes, tungsten alloys can acquire varying degrees of plasticity. In scientific research, plasticity can be assessed by bending thin materials.

[0003] Existing plasticity testing devices require two sets of drive equipment when bending thin materials, one to clamp the thin material and the other to drive the pressure plate to rotate, so that the thin material is bent to test its plasticity, resulting in high operating costs. Summary of the Invention

[0004] The purpose of this application is to provide a plasticity testing device for tungsten alloy thin materials in order to solve the above problems. It adopts a single set of driving components, which can simultaneously drive the clamping of the thin material and then drive the pressure plate to rotate, so as to bend the thin material, and the cost of use is lower.

The stationary clamping block is fixed to the top surface of the worktable, and the movable clamping block is movably disposed on the top surface of the worktable, able to approach or move away from the stationary clamping block to clamp the thin material between them. The bottom of the movable clamping block is fixedly connected to a connecting rod that passes through the worktable, and a groove adapted to the connecting rod is provided on the worktable. The pressure plate is connected to a transmission component that drives its rotation to bend the thin material between the stationary and movable clamping blocks.

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0022] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0023] like Figure 1-4 As shown, a plasticity testing device for tungsten alloy thin materials includes a worktable 1, a stationary clamping block 2, a movable clamping block 3, a pressure plate 4, a cylinder support 5, a cylinder 6, a connecting rod 11, a linkage block 17, a lever 18, and a return lever 19. The stationary clamping block 2 is fixed to the top surface of the worktable 1. The movable clamping block 3 is movably disposed on the top surface of the worktable 1, allowing it to approach or move away from the stationary clamping block 2 to clamp the thin material between them. The bottom of the movable clamping block 3 is fixedly connected to a connecting rod 11 that penetrates the worktable 1, and the worktable 1 is provided with an adapter for the connecting rod 11. The slide groove of 1, the pressure plate 4 is connected to the transmission component to drive its rotation to bend the thin material between the static clamping block 2 and the moving clamping block 3, the cylinder 6 is fixedly installed on the worktable 1 through the cylinder bracket 5, the telescopic end of the cylinder 6 is provided with an elastic element that can push the connecting rod 11, the end of the telescopic end of the cylinder 6 is also fixedly provided with a toggle block 18, the linkage block 17 is fixedly connected to the transmission component, and the linkage block 17 can be toggled by the toggle block 18 for transmission, the side of the toggle block 18 is also fixedly provided with a return lever 19 that can toggle the connecting rod 11.

[0024] Specifically, the extension and retraction of cylinder 6 causes the connecting rod 11 to move via the elastic element, which in turn causes the moving clamping block 3 to move and cooperate with the stationary clamping block 2 to clamp the thin material. At the same time, the elastic element does not affect the continued extension of cylinder 6. Then, the toggle block 18 moves the linkage block 17, and under the action of the transmission component, the pressure plate 4 rotates and bends the thin material. When cylinder 6 retracts, the toggle block 18 moves the linkage block 17 back, thereby causing the pressure plate 4 to return to its original position. At the same time, the return lever 19 moves the connecting rod 11 back to its original position.

[0025] Furthermore, the transmission assembly includes a housing 12, a rotating shaft 13, a turntable 14, a rack 15, and a gear 16. The housing 12 is fixedly installed on the bottom surface of the worktable 1. The rotating shaft 13 is located inside the housing 12. One end of the rotating shaft 13 is provided with a turntable 14, and the turntable 14 is rotatably connected to the worktable 1. The other end of the rotating shaft 13 is fixedly provided with a gear 16. The rack 15 is slidably engaged with the inside of the housing 12, and the rack 15 meshes with the gear 16. The linkage block 17 is fixedly connected to the end of the rack 15.

[0026] Specifically, the lever 18 pushes the linkage block 17 to move horizontally, which in turn drives the rack 15 to move horizontally. The rack 15 meshes with and drives the gear 16 to rotate. The rotating shaft 13 and the turntable 14 rotate synchronously with the gear 16, while the pressure plate 4 rotates at the same time.

[0027] Furthermore, the elastic element includes a connecting block 7, a sliding rod 8, a limiting plate 9, and a spring 10. One end of the connecting block 7 is fixedly connected to the telescopic arm of the cylinder 6, one end of the sliding rod 8 passes through the other end of the connecting block 7, and the sliding rod 8 slides in cooperation with the connecting block 7. Both ends of the sliding rod 8 are fixedly connected to the limiting plate 9, and the spring 10 is sleeved on the outside of the sliding rod 8.

[0028] Specifically, the slide bar 8 on the connecting block 7 first pushes the connecting rod 11, which in turn pushes the moving clamping block 3. After the stationary clamping block 2 and the moving clamping block 3 clamp the alloy thin material, the moving clamping block 3 can no longer move. At this time, the slide bar 8 slides on the connecting block 7, so that the cylinder 6 can continue to extend and can maintain the state of clamping the thin material under the push of the spring 10.

[0029] Furthermore, the turntable 14 is connected to the worktable 1 via bearings to ensure stable rotation of the turntable 14.

[0030] Furthermore, the horizontally positioned cylinder 6 can horizontally extend and retract to move the elastic element and the toggle block 18.

[0031] Furthermore, the toggle block 18 is U-shaped, and the linkage block 17 is located inside the toggle block 18.

[0032] Specifically, the U-shaped lever 18 will not move the linkage block 17 temporarily when the elastic element moves first. After the elastic element pushes the movable clamping block 3 into place, the lever 18 contacts the linkage block 17 and then pushes the linkage block 17 to move, thereby causing the pressure plate 4 to rotate.

[0033] Furthermore, the shaft 13 is axially perpendicular and rotates on the housing 12, providing stable support and transmission.

[0034] In the above structure, the alloy sheet to be tested is placed between the stationary clamping block 2 and the moving clamping block 3. Then, the cylinder 6 is activated to extend, driving the connecting block 7 and the lever 18 to move synchronously. The slide bar 8 on the connecting block 7 first pushes the connecting rod 11, which in turn pushes the moving clamping block 3. After the stationary clamping block 2 and the moving clamping block 3 clamp the alloy sheet, the moving clamping block 3 can no longer move. At this time, the slide bar 8 slides on the connecting block 7, so that the cylinder 6 can continue to extend. Then, the lever 18 pushes the linkage block 17 to translate, and then the linkage block 17 drives the rack 15 to translate. The rack 15 meshes and drives the gear 16 to rotate. The rotating shaft 13 and the turntable 14 rotate synchronously with the gear 16. At the same time, the pressure plate 4 rotates, causing the alloy sheet to bend towards the moving clamping block 3. After completion, the cylinder 6 retracts, causing the lever 18 to drive the linkage block 17 to shift, and then the pressure plate 4 returns to its position. At the same time, the return lever 19 drives the connecting rod 11 to return to its position. The plasticity is judged based on the bending angle of the sheet.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application.
