Description

Technical Field

[0001] This utility model relates to the field of building steel quality testing technology, specifically to a building steel toughness testing device. Background Technology

[0002] Construction steel refers to various types of steel materials used in construction projects. Its toughness is an indicator of material quality, representing the material's ability to absorb energy during deformation and fracture. Generally, the toughness of construction steel needs to be tested after it leaves the factory.

[0003] Publication No. CN119470099A discloses a steel toughness testing device, which includes a support unit and an impact unit. The support unit clamps both ends of the steel pipe, and a cylinder drives the impact unit downward, causing the impact blades to strike the steel pipe with varying forces. This solves the problem that existing toughness testing machines cannot be adapted to building steel pipes. However, steel pipes come in various specifications with significant diameter differences, and fixed-specification clamping mechanisms cannot effectively fix steel pipes of different sizes. Therefore, we propose a steel toughness testing device for building materials. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a device for testing the toughness of building steel.

[0005] The technical solution adopted by this utility model to solve its technical problem is a toughness testing device for building steel, including a device base. One end of the device base is provided with a movable connecting plate. The surface of the movable connecting plate away from the device base is provided with a splicing groove. The splicing groove is spliced ​​with an extension splicing plate through a snap-fit ​​plug. The extension splicing plate is integrally constructed on the side wall of a first detachable clamping base. An arc-shaped clamping groove is provided in the center of the top surface of the first detachable clamping base. Threaded rods are integrally constructed on both sides of the arc-shaped clamping groove at the top of the first detachable clamping base. A clamping plate is inserted into the first detachable clamping base through the threaded rods. The threaded rods are inserted into a mounting groove that is opened through the surface of the clamping plate and matches it. An adjusting threaded groove for adjusting the clamping width is rotatably connected inside the mounting groove.

[0006] A drive motor is installed inside the base of the device on the side facing the movable connecting plate. The extension end of the drive motor is equipped with a drive screw, and the drive motor is connected to the movable connecting plate through the drive screw.

[0007] By adopting the above technical solution, firstly, according to the shape characteristics of the steel, the two limiting plugs on the surface of the extended splicing plate are removed, and the corresponding model of the first detachable clamping base is replaced. The bottom end of the arc-shaped clamping groove on the surface of each first detachable clamping base is flush with the bottom end of the groove of the central clamping base. Then, the steel is passed through the arc-shaped clamping groove on the surface of the first detachable clamping base, the central clamping base, and the arc-shaped clamping groove on the surface of the threaded rod. The threaded groove is rotated and adjusted to push the clamping plate towards the first detachable clamping base by rotating the connecting piece inside the installation groove until the steel is clamped and fixed. The clamping mechanism that is easy to disassemble and clamp can be adapted to steel of different shapes, diameters and types to be tested, which improves the scope of application and is easy to disassemble and operate.

[0008] When the length of the steel to be tested is short, the transmission motor drives the transmission screw to rotate. The movable connecting plate moves toward or away from the device base as the transmission screw rotates, which is limited by the limit rods on both sides. This makes it easy to clamp steel of different lengths and avoids the situation where the steel is too short to be effectively clamped on both sides.

[0009] Specifically, a central clamping base with the same height as the arc-shaped clamping groove is provided at the center of the top of the device base, and a detection device is provided at the center of the surface of the central clamping base.

[0010] By adopting the above technical solution, the pressure on each side of the steel is made equal during the testing process by using arc-shaped clamping bases of the same height.

[0011] Specifically, a rotating connector is provided on the outer periphery of the bottom end of the adjusting thread groove, and the rotating connector is rotatably connected to a matching groove opened inside the mounting groove.

[0012] By adopting the above technical solution, the adjusting thread groove rotates within the clamping plate by rotating the connecting piece, and then rotates into the outer circumference of the threaded rod, thereby driving the clamping plate to move downwards to clamp the steel to be tested.

[0013] Specifically, the device base has a second detachable clamping base with the same structure as the first detachable clamping base, which is detachably installed at the end away from the movable connecting plate.

[0014] By adopting the above technical solution, a second detachable clamping base with a relatively fixed position is set at the end of the device base away from the end that can be extended and adjusted in length, in order to cooperate with the first detachable clamping base to clamp and fix the steel to be tested.

[0015] Specifically, the sidewall of the movable connecting plate is connected to limit rods on both sides of the transmission screw, and the limit rods are fixedly connected to the inside of the device base.

[0016] By adopting the above technical solution, when the transmission screw moves with the transmission motor and drives the movable connecting plate to move, the displacement state of the movable connecting plate is restricted by the limit rod, so that its movement is along the horizontal direction of the device base.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The technical solution of this application firstly removes two limiting plugs from the surface of the extended splicing plate according to the shape characteristics of the steel, and replaces the first detachable clamping base of the corresponding model. The bottom end of the arc-shaped clamping groove on the surface of each first detachable clamping base is flush with the bottom end of the groove of the central clamping base. Then, the steel is passed through the arc-shaped clamping groove on the surface of the first detachable clamping base, the central clamping base and the arc-shaped clamping groove on the surface of the threaded rod. The threaded groove is rotated and adjusted to push the clamping plate towards the first detachable clamping base by rotating the connecting piece inside the installation groove until the steel is clamped and fixed. The clamping mechanism that is easy to disassemble and clamp can be adapted to steel of different shapes, diameters and types to be tested, which improves the scope of application and is easy to disassemble and operate.

[0019] When the length of the steel to be tested is short, the transmission motor drives the transmission screw to rotate. The movable connecting plate moves toward or away from the device base as the transmission screw rotates, which is limited by the limit rods on both sides. This makes it easy to clamp steel of different lengths and avoids the situation where the steel is too short to be effectively clamped on both sides. Attached Figure Description

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-3 This utility model provides a technical solution: a toughness testing device for building steel, including a device base 1, a movable connecting plate 2 at one end of the device base 1, a splicing groove 3 on the surface of the movable connecting plate 2 away from the device base 1, the splicing groove 3 being spliced ​​with an extension splicing plate 5 through a snap-fit ​​plug, and the extension splicing plate 5 being integrally constructed on the side wall of a first detachable clamping base 4, an arc-shaped clamping groove 6 being centrally located on the top surface of the first detachable clamping base 4, threaded rods 7 being integrally constructed on both sides of the top of the first detachable clamping base 4, a clamping plate 8 being inserted into the first detachable clamping base 4 through the threaded rods 7, and the threaded rods 7 being inserted into an installation groove 9 that is opened through the surface of the clamping plate 8 and fits therewith, the installation groove 9 being rotatably connected to an adjusting threaded groove 10 for adjusting the clamping width;

[0027] A drive motor 13 is installed inside the base 1 facing the movable connecting plate 2. The extended end of the drive motor 13 is equipped with a drive screw 14, and the drive motor 13 is connected to the movable connecting plate 2 through the drive screw 14.

[0028] In use, firstly, according to the shape characteristics of the steel, remove the two limiting plugs on the surface of the extension splicing plate 5, and replace it with the corresponding model of the first detachable clamping base 4. The bottom end of the arc-shaped clamping groove 6 opened on the surface of each first detachable clamping base 4 is flush with the bottom end of the groove of the center clamping base 16. Then, pass the steel through the arc-shaped clamping groove 6 opened on the surface of the first detachable clamping base 4, the center clamping base 16, and the arc-shaped clamping groove 6 opened on the surface of the threaded rod 7. Rotate the adjusting threaded groove 10 to push the clamping plate 8 towards the first detachable clamping base 4 by rotating the connecting piece 11 inside the mounting groove 9 until the steel is clamped and fixed. The clamping mechanism that is easy to disassemble and clamp can be adapted to steel of different shapes, diameters and types to be tested, which improves the scope of application and is easy to disassemble and operate.

[0029] When the length of the steel to be tested is short, the transmission screw 14 is driven to rotate by the transmission motor 13. The movable connecting plate 2 moves toward or away from the device base 1 as the transmission screw 14 rotates, which is limited by the limit rods 15 on both sides. This makes it easier to clamp steel of different lengths and avoids the situation where the steel is too short to be effectively clamped on both sides.

[0030] As shown in the figure, a central clamping base 16 with the same height as the arc-shaped clamping groove 6 is provided at the center of the top of the device base 1, and a detection device is provided at the center of the surface of the central clamping base 16.

[0031] During use, the pressure on each side of the steel is equalized by using arc-shaped clamping bases of the same height during the testing process.

[0032] As shown in the figure, a rotating connector 11 is provided on the outer periphery of the bottom end of the adjusting thread groove 10, and the rotating connector 11 is rotatably connected to a matching groove opened inside the mounting groove 9.

[0033] In use, by rotating the connector 11, the adjusting thread groove 10 rotates inside the clamping plate 8 and is screwed into the outer circumference of the threaded rod 7, thereby driving the clamping plate 8 to move downward to clamp the steel to be tested.

[0034] As shown in the figure, the device base 1, which is away from the movable connecting plate 2, is detachably equipped with a second detachable clamping base 12, which has the same structure as the first detachable clamping base 4.

[0035] In use, a second detachable clamping base 12 with a relatively fixed position is set at the end of the device base 1 away from the end that can be extended and adjusted in length, in order to cooperate with the first detachable clamping base to clamp and fix the steel to be tested.

[0036] As shown in the figure, the sidewall of the movable connecting plate 2 is connected to the two sides of the transmission screw 14 by limit rods 15, and the limit rods 15 are fixedly connected to the inside of the device base 1.

[0037] In use, when the transmission screw 14 rotates with the transmission motor 13 and drives the movable connecting plate 2 to move, the displacement state of the movable connecting plate 2 is restricted by the limit rod 15, so that its movement is along the horizontal direction of the device base 1.

[0038] The working principle and usage process of this utility model are as follows: First, based on the shape characteristics of the steel, remove the two limiting plugs on the surface of the extended splicing plate 5, and replace them with the corresponding model of the first detachable clamping base 4. The bottom end of the arc-shaped clamping groove 6 on the surface of each first detachable clamping base 4 is flush with the bottom end of the groove of the central clamping base 16. By using arc-shaped clamping bases of the same height, the pressure on each side of the steel is made equal during the testing process. Then, the steel is passed through the arc-shaped clamping groove 6 on the surface of the first detachable clamping base 4, the central clamping base 16, and the arc-shaped clamping groove 6 on the surface of the threaded rod 7. Rotating the adjusting threaded groove 10 pushes the clamping plate 8 towards the first detachable clamping base 4 by rotating the rotating connector 11 inside the mounting groove 9 until the steel is clamped and fixed. A second detachable clamping base 12, with a relatively fixed position, is set at the end of the base 1 that is away from the adjustable length. This base works in conjunction with the first detachable clamping base to clamp and fix the steel to be tested. The clamping mechanism, which is easy to disassemble and fix, can adapt to steels of different shapes, diameters, and types, thus improving its applicability. It is also easy to assemble and disassemble and is simple to operate. When the length of the steel to be tested is short, the transmission screw 14 is driven to rotate by the transmission motor 13. When the transmission screw 14 rotates with the transmission motor 13 and drives the movable connecting plate 2 to move, the displacement state of the movable connecting plate 2 is limited by the limit rod 15, so that it can move along the horizontal direction of the device base 1. This facilitates clamping steels of different lengths and avoids the situation where the steel is too short to be effectively clamped on both sides.
