Description

Technical Field

[0001] This utility model relates to a metal mechanical property testing device, specifically a nickel-based high-temperature alloy tensile property testing device, belonging to the technical field of alloy testing devices. Background Technology

[0002] Alloy materials are solid products with metallic properties obtained by mixing and melting a metal with one or more other metals or non-metals, cooling and solidifying them. After the production of alloy materials, testing equipment is needed to check whether they are qualified. Nickel-based alloys are a class of alloys with high strength and certain resistance to oxidation and corrosion at high temperatures of 650 to 1000℃. The main alloying elements are copper, chromium and molybdenum.

[0003] Chinese Patent Application Publication No. CN221667483U discloses a tensile property testing device for nickel-based high-temperature alloys. This utility model can prevent the sudden fracture of the alloy from causing debris and the broken alloy to fly everywhere, effectively protecting workers from injury. At the same time, the protective door is fixed by a press-to-lock buckle, which is simple and stable.

[0004] While the aforementioned patent solution can prevent debris from flying everywhere when the alloy breaks, the testing device in the aforementioned patent only uses a metal fixing platform to fix and stretch the alloy. When clamping cylindrical or irregular shapes, the contact area between the fixing platform and the alloy is narrow, which makes it easy for the alloy to fall off during stretching, affecting the alloy testing results.

[0005] Therefore, a device for testing the tensile properties of nickel-based superalloys is proposed here. Utility Model Content

[0006] This invention proposes a tensile property testing device for nickel-based high-temperature alloys, which can increase the contact area between the anti-slip pad and the alloy material, thereby improving the stability of the alloy material when clamped at both ends during testing. Furthermore, the use of a protective frame can prevent material breakage and splashing, increasing the safety of testing personnel.

[0007] This utility model is achieved through the following technical solution: a nickel-based high-temperature alloy tensile property testing device, including a protective shell, a protective frame rotatably connected to one side of the protective shell, an observation window opened on one side of the protective frame, a snap-fit ​​assembly for fixing the position of the protective frame on one side of the protective shell, the snap-fit ​​assembly including a connecting rod fixed to one side of the protective shell and a positioning rod fixed to one side of the protective frame, a positioning frame rotatably sleeved around the connecting rod, and a lever fixed to one side of the positioning frame.

[0008] The protective shell has two connecting plates inside. Two connecting brackets are provided on the sides of the two connecting plates that are close to each other. Each connecting bracket has a clamping assembly on one side for fixing the alloy. The clamping assembly includes a first clamping block that slides inside the connecting bracket. A first arc-shaped rod that slides inside the connecting bracket is fixed to one side of the first clamping block. A set of second clamping blocks slides inside the first clamping block. A second arc-shaped rod that slides inside the first clamping block is fixed to one side of the second clamping block. A set of third clamping blocks slides inside the second clamping block. A third arc-shaped rod that slides inside the second clamping block is fixed to one side of the third clamping block. An anti-slip pad is fixed to one side of each third clamping block.

[0009] Furthermore, the connecting plate has a positioning hole inside, and a limiting groove is formed on one side of the connecting plate near the connecting frame. A first threaded rod is rotatably connected inside the limiting groove, and a transmission block that slides inside the limiting groove is threaded around the first threaded rod. The transmission block is fixed to one side of the connecting frame.

[0010] Furthermore, one end of the first threaded rod rotatably passes through one side of the connecting plate and is fixedly sleeved with a transmission frame, and the transmission frame rotates outside the connecting plate.

[0011] Furthermore, the protective shell is equipped with a lifting assembly that drives the upper connecting plate to move. The lifting assembly includes a motor fixed to the top surface of the protective shell, and a second threaded rod is fixed to the output end of the motor. A transmission sleeve fixed to the top surface of the connecting plate is threaded around the outer periphery of the second threaded rod.

[0012] Furthermore, a connecting sleeve is rotatably sleeved around the periphery of the second threaded rod, and the connecting sleeve is fixedly sleeved inside the protective shell.

[0013] Furthermore, a limiting slide rod is fixed on the top surface of the connecting plate mentioned above, and a limiting sleeve fixed inside the protective shell is slidably sleeved around the limiting slide rod.

[0014] This invention provides a device for testing the tensile properties of nickel-based superalloys, which has the following advantages:

[0015] 1. The nickel-based high-temperature alloy tensile property testing device uses a rotating transmission frame to drive the first threaded rod to rotate, and through the transmission block, it drives one of the connecting frames to move, so that multiple third clamping blocks come into contact with the surface of the alloy material. The alloy is used to compress the third clamping blocks and the second clamping blocks, so that the angles of the first clamping block, the second clamping block and the third clamping block can be adjusted according to the shape of the alloy material to increase the contact area between the anti-slip pad and the alloy material, thereby improving the stability of the alloy material clamped at both ends during testing.

[0016] 2. After the material is fixed, the protective frame is closed, and then the lever is moved to rotate the positioning frame on the surface of the connecting rod, so that the positioning frame is fixed in position with the positioning rod. Then the testing process can be observed through the observation window, which can avoid material breakage and splashing, and increase the safety of the testing personnel.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0030] Please see Figures 1-4 The present invention proposes the following implementation scheme: a nickel-based high-temperature alloy tensile property testing device, including a protective shell 1, a protective frame 2 rotatably connected to one side of the protective shell 1, an observation window 21 opened on one side of the protective frame 2, a snap-fit ​​assembly 3 for fixing the position of the protective frame 2 on one side of the protective shell 1, the snap-fit ​​assembly 3 including a connecting rod 31 fixed to one side of the protective shell 1 and a positioning rod 34 fixed to one side of the protective frame 2, a positioning frame 32 rotatably sleeved around the connecting rod 31, and a lever 33 fixed on one side of the positioning frame 32.

[0031] In the above scheme, after the test material is fixed, the protective frame 2 is closed, and then the lever 33 is moved to drive the positioning frame 32 to rotate on the surface of the connecting rod 31, so that the positioning frame 32 fixes the position of the positioning rod 34. Then the test process can be observed through the observation window 21, which can increase the safety of the test personnel.

[0032] Please refer to this carefully. Figure 2 and Figure 3 The protective shell 1 has two connecting plates 4 inside. Two connecting brackets 6 are provided on the side of the two connecting plates 4 that are close to each other. Each connecting bracket 6 has a clamping assembly 7 on one side to fix the alloy. The clamping assembly 7 includes a first clamping block 71 that slides inside the connecting bracket 6. A first arc-shaped rod 74 that slides inside the connecting bracket 6 is fixed on one side of the first clamping block 71. A set of second clamping blocks 72 slides inside the first clamping block 71. A second arc-shaped rod 75 that slides inside the first clamping block 71 is fixed on one side of the second clamping block 72. A set of third clamping blocks 73 slides inside the second clamping block 72. A third arc-shaped rod 76 that slides inside the second clamping block 72 is fixed on one side of the third clamping block 73. An anti-slip pad 77 is fixed on one side of each third clamping block 73.

[0033] In the above scheme, the movable connecting frame 6 makes multiple third clamping blocks 73 contact the surface of the alloy material, and uses the alloy to squeeze the third clamping blocks 73 and the second clamping blocks 72, so that the angles of the first clamping block 71, the second clamping block 72 and the third clamping block 73 can be adjusted according to the shape of the alloy material.

[0034] Please refer to this carefully. Figure 3 The connecting plate 4 has a positioning hole 41 inside. The connecting plate 4 has a limiting groove 42 on one side near the connecting frame 6. A first threaded rod 43 is rotatably connected inside the limiting groove 42. A transmission block 44 that slides inside the limiting groove 42 is threaded around the first threaded rod 43. The transmission block 44 is fixed to one side of the connecting frame 6.

[0035] One end of the first threaded rod 43 rotates through one side of the connecting plate 4 and is fixedly sleeved with the transmission frame 45, and the transmission frame 45 rotates outside the connecting plate 4.

[0036] In the above scheme, the rotary transmission frame 45 drives the first threaded rod 43 to rotate, and drives one of the connecting frames 6 to move through the transmission block 44.

[0037] Please refer to this carefully. Figure 2 The protective shell 1 is equipped with a lifting assembly 5 that drives the upper connecting plate 4 to move. The lifting assembly 5 includes a motor 51 fixed on the top surface of the protective shell 1. The output end of the motor 51 is fixed with a second threaded rod 52. The outer periphery of the second threaded rod 52 is threaded with a transmission sleeve 53 fixed on the top surface of the connecting plate 4.

[0038] The outer periphery of the second threaded rod 52 is rotatably sleeved with a connecting sleeve 54, and the connecting sleeve 54 is fixedly sleeved inside the protective shell 1.

[0039] In the above scheme, the starting motor 51 drives the second threaded rod 52 to rotate inside the connecting sleeve 54, and drives the connecting plate 4 to move upward through the transmission sleeve 53, which can detect the clamped alloy material.

[0040] A limiting slide rod 8 is fixed on the top surface of the upper connecting plate 4, and a limiting sleeve 9 fixed inside the protective shell 1 is slidably sleeved around the limiting slide rod 8.

[0041] In use, the two ends of the test material are placed inside the positioning holes 41 on the surfaces of the two connecting plates 4. Then, the rotating transmission frame 45 drives the first threaded rod 43 to rotate, and through the transmission block 44, it drives one of the connecting frames 6 to move, so that multiple third clamping blocks 73 come into contact with the surface of the alloy material. The alloy is used to squeeze the third clamping blocks 73 and the second clamping blocks 72, so that the angles of the first clamping blocks 71, the second clamping blocks 72 and the third clamping blocks 73 can be adjusted according to the shape of the alloy material to increase the contact area between the anti-slip pad 77 and the alloy material, thereby improving the stability of the alloy material being clamped at both ends during testing. After the test material is fixed, the protective frame 2 is closed, and then the lever 33 is moved to drive the positioning frame 32 to rotate on the surface of the connecting rod 31, so that the positioning frame 32 fixes the position of the positioning rod 34. Then, the testing process is observed through the observation window 21, which can increase the safety of the testing personnel. Then, the motor 51 is started to drive the second threaded rod 52 to rotate inside the connecting sleeve 54, and through the transmission sleeve 53, it drives the connecting plate 4 to move upward, which can test the clamped alloy material.
