Description

Technical Field

[0001] This utility model relates to the field of material strength testing technology, specifically a new material tensile strength testing device. Background Technology

[0002] The rapid development of the aviation industry has placed stringent demands on the performance of new materials, especially their strength properties, which are directly related to the structural safety and operational reliability of aircraft. New aviation materials, such as titanium alloys, carbon fiber composites, and shape memory alloys, must withstand complex mechanical stresses under extreme operating conditions.

[0003] Tensile strength, as a core indicator, determines a material's ability to resist fracture under tensile loads and is a crucial basis for material selection, structural design, and safety assessment. Therefore, accurate testing of the tensile strength of such materials has become an indispensable and important step in the research, development, production, and application of aerospace materials.

[0004] When some new materials (such as carbon fiber) are subjected to high tensile force and break, they will produce debris that will fly at high speed in all directions. This debris can cause scratches to accumulate on the inner wall of the equipment, affecting the surface finish and potentially causing safety issues.

[0005] Therefore, a new material tensile strength testing device is proposed to address the above problems. Utility Model Content

[0006] The main objective of this invention is to provide a new material tensile strength testing device to solve the technical problem in existing new material tensile strength testing devices that, when certain new materials are subjected to high tensile force and break, they generate debris that flies out at high speed in all directions. This debris causes accumulated scratches on the inner wall of the device, affecting the surface finish and potentially causing safety issues.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A new material tensile strength testing device of this utility model includes a main body, an internal space of which is formed. Two opposing upright plates of the main body are each equipped with a cylinder. The output end of each cylinder passes through the internal space and is connected to a C-shaped plate, so that the C-shaped plates connected to the two cylinders face each other and can move away from or towards each other under the drive of the cylinders, thereby forming a test space that can be opened or closed within the internal space. A limiting plate is vertically arranged within the test space. The top plate of the main body is fixedly connected to the top of the limiting plate. A motor is connected to one horizontal end of the top plate on the side away from the internal space. The output end of the motor passes through the test space and connects to a vertically arranged threaded rod, allowing the threaded rod to rotate within the test space. A movable plate is rotatably connected to the threaded rod. The limiting plate has a limiting groove for sliding the movable plate. Clamping components are connected to the bottom of the movable plate and the upper side of the bottom plate of the main body.

[0009] Preferably, the connecting plate has a groove parallel to the line connecting the second clamp to the first clamp, and the bolt passes through the groove from the side wall of the connecting plate in a direction parallel to the groove, and connects with the threaded hole of the second clamp extending into the groove.

[0010] Preferably, the C-shaped plate includes a main body plate for connecting the output end of the cylinder, and the two sides of the main body plate are bent and extended toward the other C-shaped plate.

[0011] Preferably, a back plate is connected to the same side of the two uprights, and the other side of the two uprights forms an opening in the equipment space.

[0012] Preferably, both the first clamp and the second clamp have protrusions on their sidewalls; the protrusions on the sidewalls of the first clamp and the second clamp are staggered; there are multiple protrusions; thus, the protrusions further fix the carbon fiber, so that the carbon fiber will not slip out due to the second clamp and the first clamp when the carbon fiber is subjected to tensile strength test.

[0013] Preferably, the C-shaped plate has multiple grooves on its surface; heating rods are provided on the inner walls of the grooves.

[0014] Preferably, the bottom of the main body of the device is connected to multiple damping spring shock absorbers.

[0015] Preferably, a suction cup is fixed to the bottom of the damping spring shock absorber.

[0016] Preferably, a sealing ring is provided at the bottom of the suction cup.

[0017] The advantages of this utility model are: 1. The new material tensile strength testing equipment described in this utility model uses a C-shaped plate to block the debris generated after the carbon fiber and other new material samples break, preventing the debris from flying around and causing safety hazards.

[0018] 2.

[0022] 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 scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5 As shown in the embodiment of this utility model, a new material tensile strength testing device includes a main body 1, with an internal space. Two opposing vertical plates of the main body 1 are each equipped with a cylinder 110. The output end of each cylinder 110 extends into the space and is connected to a C-shaped plate 111, so that the C-shaped plates 111 connected to the two cylinders 110 face each other and can move away from or towards each other under the drive of the cylinders 110, thereby forming a test space that can be opened or closed within the space. A limit plate 10 is vertically arranged within the test space. 5; The top end of the limiting plate 105 is fixedly connected to the top plate 102 of the main body 1 of the equipment; a motor 103 is connected to one horizontal end of the top plate 102 on the side away from the equipment space; the output end of the motor 103 passes into the test space to connect to the vertically arranged threaded rod 101 so that the threaded rod 101 can rotate in the test space; a moving plate 104 is rotatably connected to the threaded rod 101; the limiting plate 105 forms a limiting groove for the moving plate 104 to slide up and down; clamping components are connected to the bottom of the moving plate 104 and the upper side of the bottom plate of the main body 1 of the equipment.

[0025] During operation, the clamping component connected to the moving plate 104 clamps one end of the new material sample, while the clamping component on the base plate of the main body 1 clamps the other end of the new material sample (e.g., a carbon fiber sample). After the new material sample is fixed, the cylinder 110 is activated, causing the C-shaped plate 111 at its output end to move. After a pair of C-shaped plates 111 come into contact, the new material sample is sealed inside the C-shaped plates 111. Then, the motor 103 is activated, causing the threaded rod 101 to rotate. This causes the threaded rod 101 to move the moving plate 104 upwards on the threaded rod 101, thereby stretching the sample. When a new material sample is subjected to tensile strength testing, a large amount of flying debris will be generated after the sample, such as carbon fiber, is subjected to high-intensity tensile stress and breaks. However, due to the shielding space formed by the C-shaped plates 111, the debris will not fly away. Thus, the C-shaped plates 111 block the debris generated after the carbon fiber and other new material samples break, preventing the debris from flying around and causing safety issues. At the same time, after the debris is collected in the C-shaped plates 111, the motor 103 stops when the test is completed, and the cylinder 110 opens the test space. The debris is collected in a small area defined by the two C-shaped plates 111 during the test, making it easier to clean up the debris.

[0026] Specifically, the clamping component includes a horizontally arranged connecting plate 106, on one side of which a first clamp 107 is fixedly connected; the connecting plate 106 is also slidably connected to a second clamp 108 along the same horizontal direction; and the side wall of the connecting plate 106 is provided with bolts 109 for adjusting the clamping distance between the first clamp 107 and the second clamp 108 along the direction from the second clamp 108 to the first clamp 107.

[0027] When using clamping components to clamp both ends of the new material sample, rotating bolt 109 drives the second clamp 108 to move, so that the second clamp 108 and the first clamp 107 fix and clamp the new material sample.

[0028] Furthermore, the connecting plate 106 has a groove parallel to the line connecting the second clamp 108 to the first clamp 107. The bolt 109 passes through the side wall of the connecting plate 106 in a direction parallel to the groove and is connected to the threaded hole of the second clamp 108 that extends into the groove.

[0029] Specifically, the C-shaped plate 111 includes a main body plate for connecting the output end of the cylinder 110, and the two sides of the main body plate are bent and extended toward the other C-shaped plate 111 respectively.

[0030] Furthermore, a back plate is connected to the same side of both upright plates, and the other side of the two upright plates forms an opening in the equipment space. The threaded rod 101 is disposed near the back plate within the test space. Therefore, when the two C-shaped plates 111 are moved away from each other, a new material sample can be clamped between the two clamping components through this opening. After the test is completed, moving the two C-shaped plates 111 away from each other facilitates the cleaning of debris through this opening.

[0031] like Figure 4 As shown, both the first clamp 107 and the second clamp 108 have protrusions 2 on their sidewalls; the protrusions 2 on the sidewalls of the first clamp 107 and the second clamp 108 are staggered; there are multiple protrusions 2; during operation, when the second clamp 108 is moved by rotating the bolt 109 to clamp and fix the carbon fiber, the protrusions 2 in the first clamp 107 and the second clamp 108 will come into contact with the carbon fiber, and when the second clamp 108 moves to fix the carbon fiber, the protrusions 2 will further clamp and fix the carbon fiber; thus, the protrusions 2 further fix the carbon fiber, so that when the carbon fiber is subjected to tensile strength test, the carbon fiber will not slip out due to the second clamp 108 and the first clamp 107.

[0032] like Figure 2 and Figure 5 As shown, the surface of the C-shaped plate 111 is provided with multiple grooves 6; the inner wall of the groove 6 is provided with a heating rod 601; when it is necessary to test the tensile strength of the new material sample at different temperatures, the new material sample is first heated to the specified temperature, and then before the tensile strength test, the temperature of the heating rod 601 in the groove 6 is adjusted to keep the test space composed of the C-shaped plate 111 warm, so that the new material sample can be kept warm in the environment during the test to perform the strength test, thereby reducing the temperature fluctuation during the test.

[0033] like Figures 1 to 5 As shown, the bottom of the main body 1 of the equipment is connected to multiple damping spring shock absorbers 3. During operation, when the tensile strength test is carried out, the impact generated after the carbon fiber is pulled and broken will cause the equipment to vibrate. The damping spring shock absorbers 3 at the bottom of the main body 1 will eliminate the vibration generated, so that the vibration will not affect the main body 1 of the equipment. Thus, the damping spring shock absorbers 3 will absorb and eliminate the vibration generated on the main body 1 of the equipment after the carbon fiber breaks, reducing the impact of the carbon fiber breaking on the equipment.

[0034] like Figures 1 to 5As shown, a suction cup 4 is fixed to the bottom of the damping spring shock absorber 3. During operation, the suction cup 4 at the bottom of the damping spring shock absorber 3 will adhere to the ground, so that the vibration caused by the breakage of carbon fiber will not cause the whole device to move slowly. The suction cup 4 will adhere to the ground, thereby strengthening the stability of the damping spring shock absorber 3. Thus, the suction cup 4 contacts and adheres to the ground, which strengthens the stability of the damping spring shock absorber 3.

[0035] like Figures 1 to 5 As shown, a sealing ring 5 is provided at the bottom of the suction cup 4. During operation, the sealing ring 5 at the bottom of the suction cup 4 will enhance the sealing performance of the suction cup 4, thereby reducing the entry of air into the suction cup 4 and enhancing the suction force of the suction cup 4. Thus, the sealing ring 5 enhances the sealing performance of the suction cup 4, thereby strengthening its suction force.

[0036] Furthermore, the base plate of the main body 1 of the device can also be configured as a horizontal pull-out type, which makes it convenient to pull out the base plate for cleaning up debris when needed.

[0037] Working principle: By rotating the bolt 109, the second clamp 108 is moved, and the second clamp 108 and the first clamp 107 fix and clamp the two ends of the carbon fiber and other new material sample. After the carbon fiber and other new material sample is fixed, the cylinder 110 is started, which drives the C-shaped plate 111 at its output end to move. After a pair of C-shaped plates 111 come into contact, the carbon fiber and other new material sample will be shielded within the C-shaped plate 111. Then, the motor 103 is started, which drives the threaded rod 101 to rotate. The threaded rod 101 will drive the moving plate 104 to move up and down on the threaded rod 101, thereby performing a tensile strength test on the carbon fiber and other new material sample. During the tensile strength test, a large amount of flying debris generated after the carbon fiber and other new material sample breaks under high-strength tension is blocked by the shielding space formed by the C-shaped plate 111, thus preventing flying and safety issues. The impact generated when the new material sample breaks will cause the equipment to vibrate. The damping spring shock absorber 3 at the bottom of the main body 1 will eliminate the vibration, so that the vibration will not affect the main body 1 of the equipment. The suction cup 4 at the bottom of the damping spring shock absorber 3 will adhere to the ground, so that the vibration generated after the carbon fiber breaks will not cause the entire equipment to move slowly. The suction cup 4 will adhere to the ground, thereby strengthening the stability of the damping spring shock absorber 3. The sealing ring 5 at the bottom of the suction cup 4 will enhance the sealing performance of the suction cup 4, thereby reducing the entry of air into the suction cup 4 and enhancing the suction force of the suction cup 4. The heating rod 601 in the groove 6 heats the shielding space composed of the C-shaped plate 111, which can provide a heat preservation environment when the new material sample is heated to different temperatures for strength testing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
