[0016] Three beneficial effects

[0017] Compared with the prior art, the present invention provides an in-situ bending mechanical property testing device, which has the following beneficial effects:

[0018] 1. This in-situ bending mechanical performance testing equipment features an enhanced active heat dissipation function through a heat dissipation mechanism. This mechanism accelerates airflow, rapidly dissipating internal heat via air cooling. Simultaneously, the filtration system filters out dust, particles, and other impurities from the flowing air. Furthermore, the storage mechanism allows for easy adjustment of the spacing between storage units, facilitating the storage of different sized test pieces. These features further enhance the equipment's functionality and practicality.

[0019] 2. This in-situ bending mechanical property testing equipment, through the setup of a mechanical testing instrument, coordinate slide, bending worktable, pin, pressure plate, pressure plate seat, and electric cylinder module, greatly facilitates the mechanical property testing of metal parts. During testing, test specimens are made to scale according to the actual usage of the metal components and bent to the required bending angle. Then, the mechanical properties are tested using a portable mechanical property testing instrument fixed above the device. This device solves two problems: First, before structural design, this device can measure the true mechanical properties of the metal material of the structure to be designed, and then perform structural design calculations based on the mechanical property parameters. Previously, only simulation software could be used for analysis, and the analysis results often differed significantly from the actual situation. Second, when it is necessary to understand the actual stress condition of structural components after a period of use, actual measurement is usually not possible. With this structure, the device can simulate the same stress and bending condition based on the actual stress condition of the metal components, and then perform mechanical property testing. Traditional methods can hardly measure the actual mechanical property parameters of steel structures, thus preventing mechanical testing of actual components. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-5 An in-situ bending mechanical performance testing device includes a heat dissipation protection cabinet 1, universal wheels 2 at the bottom of the heat dissipation protection cabinet 1, a controller 3 fixedly installed on the front of the heat dissipation protection cabinet 1, an operation panel 4 fixedly installed on the top of the heat dissipation protection cabinet 1, a bending worktable 5 on the top of the operation panel 4, a pressure plate seat 6 on the top of the operation panel 4, two pressure plates 7 on the top of the pressure plate seat 6, two test blocks 8 inside the bending worktable 5, two pins 9 inside the bending worktable 5, a coordinate slide 10 on the top of the bending worktable 5, a mechanical testing instrument 11 on the top of the coordinate slide 10, a heat dissipation mechanism 12 on the left side of the heat dissipation protection cabinet 1, a filtering mechanism 13 on the right side of the heat dissipation protection cabinet 1, and a placement mechanism 14 on the back of the heat dissipation protection cabinet 1.

[0028] In this embodiment, the heat dissipation protection cabinet 1 provides installation and fixation for the equipment; the casters 2 facilitate equipment movement; the controller 3 is a PLC controller used to control the movement of the electric cylinder module and set the output pressure; the operation panel 4 facilitates equipment installation and fixation and provides an operating platform; the bending workbench 5 is connected to the coordinate slide 10 at the top and to the heat dissipation protection cabinet 1 and the electric cylinder module at the bottom; it has eight through holes on its side for installing pins 9, with four through holes in each of two layers, providing a bending platform for the test block 8; the layer of pins 9 is selected based on the bending angle of the test piece; the two oblong holes on the pressure plate seat 6 are used to install the pressure plate 7, which can be installed according to the test requirements. The distance between the two pressure plates 7 can be adjusted within a certain range. The pressure plate seat 6 has eight bolt holes inside for connection with the electric cylinder module. There are two pressure plates 7, which are symmetrically installed on the pressure plate seat 6 and connected by bolts. The upper part of the pressure plate 7 is circular. The pin 9 is installed in the through hole of the bending table 5 to provide a reverse fulcrum for the specimen during bending. The circular shape ensures that the specimen can rotate around the pin 9 during bending. The coordinate slide 10 provides a connection interface with the mechanical testing instrument 11 and the bending table 5, so that the instrument can measure the mechanical properties of the specimen and move the X and Y coordinates during measurement to adjust the position of the test point. The mechanical testing instrument 11 can be equipped with various indenters, such as spherical indenters, Vickers indenters, and Knoop indenters, to perform various mechanical property tests on the specimen.

[0029] Usage steps:

[0030] 1) First, start the axial fan 123 to make it start to rotate, further drawing the air from the left side of the heat sink 121 and delivering it to the inside of the heat sink protection cabinet 1 through the two first ventilation mesh plates 124. When maintenance is required, simply pull the axial fan 123 and it can slide directly away from the heat sink 121 through the setting of the slider 122.

[0031] 2) Then, the cold air will carry the heat inside the heat dissipation protection cabinet 1 through the second ventilated mesh plate 133 into the interior of the filter box 131. After being filtered by the filter mesh plate 134, all impurities will be filtered out. When maintenance is required, simply pull the filter mesh plate 134 from the top to make the filter mesh plate 134 slide away from the filter box 131 through the limit plate 132 for replacement and maintenance.

[0032] 3) Then, according to the usage requirements, push the placement plate 142 up and down to make it slide on the mounting plate 141 and adjust the position. When it is adjusted to a suitable position, simply align the rotating rod 144 and the card plate 145 with the slot, insert them directly, and rotate them 90 degrees so that the card plate 145 is locked inside the heat dissipation protection cabinet 1. This will fix the height of the placement plate 142, thereby making it easier to adjust the spacing between the placement plates 142.

[0033] 4) Install the specimen on the testing equipment. According to the in-situ testing requirements, bend the specimen to the same shape as the specimen to be designed or tested. Then fix the mechanical testing instrument 11 on the equipment to perform mechanical testing on the bent specimen. The device is equipped with a coordinate slide 10, which allows the machine to move within a certain range of X and Y coordinates without disassembly, thereby realizing mechanical testing at different points of the test part. Thus, the relevant mechanical performance test of the specimen can be completed in one fixation.

[0034] In summary, this in-situ bending mechanical performance testing equipment, through the addition of a heat dissipation mechanism 12, possesses superior active heat dissipation capabilities. Active heat dissipation accelerates airflow, rapidly dissipating internal heat through air cooling. Simultaneously, the filtration mechanism 13 filters the flowing air, removing dust, particles, and other impurities. Furthermore, the placement mechanism 14 allows for easy adjustment of the spacing of the storage devices, facilitating the storage of test pieces of different sizes. These features further enhance the equipment's functionality and practicality.

[0035] Furthermore, the setup of the mechanical testing instrument 11, coordinate slide 10, bending worktable 5, pin 9, pressure plate 7, pressure plate seat 6, and electric cylinder module greatly facilitates the mechanical performance testing of metal parts. During testing, test pieces are made to scale according to the actual usage of the metal components and bent to the required bending angle. Then, the mechanical performance is tested using a portable mechanical performance testing instrument fixed above the device. This device solves two problems: First, before structural design, this device can measure the true mechanical properties of the metal material of the structure to be designed, and then perform structural design calculations based on the mechanical performance parameters. Previously, only simulation software could be used for analysis, and the analysis results often differed greatly from the actual situation. Second, when it is necessary to understand the actual stress condition of structural components that have been used for a period of time, actual measurement is usually not possible. With this structure, the device can simulate the same stress and bending condition based on the actual stress condition of the metal components, and then perform mechanical performance testing. Traditional methods can hardly measure the actual mechanical performance parameters of steel structures, so mechanical testing of actual components is not possible.
