Description

Technical Field

[0001] The invention relates to the technical field related to metal material devices, and in particular to a metal material physical property experimental device. Background Art

[0002] Metal materials refer to materials with properties such as gloss, ductility, easy conductivity and heat transfer. They are generally divided into ferrous metals and non-ferrous metals. Ferrous metals include iron, chromium and manganese, among which steel is the basic structural material, known as the "skeleton of industry". Tensile test is one of the important indicators for detecting metal properties. The precise marking of the specimen gauge in the tensile test is an important parameter to ensure the accuracy of the tensile results.

[0003] The publication number CN215812066U discloses a metal material physical property experimental device, including a mobile base, a plurality of storage drawers are arranged inside a rectangular support column, a workbench is arranged on the top of the rectangular support column, a material stretching device is arranged on one side of the top surface of the workbench, a universal support tube is arranged on the top of the material stretching device, a display cross clamping claw is arranged on the top of the universal support tube, and rubber protrusions are arranged on the top of the display cross clamping claw, and a material fixing device is arranged on the other side of the top surface of the workbench. The remaining three sides of the workbench except the front are all provided with transparent explosion-proof panels, and a millimeter scale is arranged on the top surface of the workbench along one side of the opening of the transparent explosion-proof panel. The device can firmly fix the metal material to be tested at one end of the device by arranging a telescopic hydraulic rod and a wrench-type metal chuck, and the tension generated by the telescopic hydraulic rod is more uniform and powerful, which is convenient for tensile testing of metal materials with different strengths.

[0004] During use, the experimental metal rod placed inside the fixing device will be continuously stretched, and the corresponding diameter of the experimental metal rod will be reduced when being stretched. Different materials can withstand different stresses, so the amount of diameter reduction is also different. Current devices often use bolts for fixing. When the diameter of some materials is reduced a lot after stretching, gaps will be generated between the bolts and the material, causing the material to loosen, which may cause severe experimental accidents. At the same time, when testing the metal rod, unidirectional stretching will cause the metal rod to be unevenly stressed, thus affecting the experimental results. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a metal material physical property experimental device to solve the problems existing in the above-mentioned background technology.

[0006] The present invention provides the following technical solutions: a metal material physical property experimental device, comprising an experimental device, the experimental device comprising a connecting plate, a side of the connecting plate is fixedly connected to a supporting device, the bottom of the supporting device is movably connected to a hydraulic device, the bottom of the hydraulic device is fixedly connected to a side connecting plate, the side of the side connecting plate is rotatably connected to a pressure plate, the other end of the pressure plate is rotatably connected to a fixing device, the bottom of the fixing device is movably connected to a connecting platform, the top of the connecting platform is fixedly connected to a fixing plate, the side of the fixing plate is fixedly connected to a connecting rod, an experimental metal rod is arranged at the center of the fixing device, the fixing device comprises a connecting shell, the interior of the connecting shell is fixedly connected to a limiting device, a fixing rod is movably connected to the limiting device, one end of the fixing rod is fixedly connected to the connecting rod, the other end of the fixing rod is fixedly connected to a clamping block, the clamping block is movably connected to the limiting device, the top of the clamping block is movably connected to a roller, the side of the roller is rotatably connected to a movable plate, the side of the movable plate is rotatably connected to the connecting shell, and the side of the movable plate is fixedly connected to a fixer;

[0007] During the demonstration experiment, the hydraulic device movably connected at the bottom of the supporting device moves downward, driving the side connecting plate and the pressure plate arranged at the bottom of the hydraulic device to move downward. The fixing device drives the fixing device to move outward during the movement, so as to stretch the experimental metal rod fixed inside the fixing device. The connecting rod and the fixing plate are fixedly connected to the connecting platform and are arranged on the inner side of the fixing device. The connecting rod is also fixedly connected to the fixing rod. When the fixing device moves outward, it drives the roller connected to the limit device and the top of the fixing rod to move. During the movement, the roller is gradually lifted by the block toward the direction of the connecting shell, so that the fixer fixedly connected at the other end of the movable plate gradually closes toward the center, so as to fix the experimental metal rod when the experimental metal rod is stretched.

[0008] During use, the experimental metal rod placed inside the fixing device will be continuously stretched, and the corresponding diameter of the experimental metal rod will be reduced when being stretched. Different materials can withstand different stresses, so the amount of diameter reduction is also different. The current device often uses bolts for fixing. When the diameter of some materials is reduced a lot after stretching, a gap will be generated between the bolts and the material, causing the material to loosen. When the device is stretched, the fixture will continue to move closer to the center, thereby reinforcing the material and avoiding loose materials and inaccurate test results. At the same time, it can also effectively reduce the risks during the experiment.

[0009] During the experiment, the hydraulic device moves downward, causing the fixing device fixed on the experimental metal rod to move to both ends. Compared with unidirectional stretching of the experimental metal rod, the bidirectional stretching of this device is more conducive to making the experimental metal rod evenly stressed and can more conveniently detect the overall physical properties of the experimental metal rod.

[0010] Furthermore, a connecting base is fixedly connected to the bottom of the experimental device, a device housing is fixedly connected to the outer side of the connecting base, an observation panel is provided on the front of the device housing, tempered glass is used for the observation panel, and steel plates are provided at the connection between the device housing and the support rod and opposite to the support rod for reinforcement.

[0011] Furthermore, a support rod is fixedly connected to the side of the device housing, a display device is fixedly connected to the side of the support rod, a camera and a detection device are arranged inside the device housing, and the camera and the detection device are connected to the display device through a line.

[0012] Furthermore, a fixing ring is fixedly connected to the side of the fixing device, and a fixing bolt is threadedly connected to the fixing ring for fixing the experimental metal rod.

[0013] Furthermore, an auxiliary connecting block is fixedly connected to the side of the hydraulic device, and a limit rod is movably connected to the center of the auxiliary connecting block. The bottom of the limit rod is fixedly connected to the connecting platform, which limits the vertical movement of the hydraulic device and reduces the force in other directions, thereby improving the accuracy of the experimental results.

[0014] Furthermore, the cross section of the block is trapezoidal, with the higher end facing the direction of the fixer, and a circular groove is provided at the center of the limiting device, and the circular groove is used to install the experimental metal rod.

[0015] Furthermore, a connecting groove is provided at the center of the connecting platform.

[0016] Furthermore, a support frame is fixedly connected to the bottom of the connecting shell, and the support frame is arranged at the connecting groove and movably connected to the connecting platform. A connecting head is fixedly connected to the side of the connecting shell, and the connecting head is rotatably connected to the pressure plate, so that the force applied by the pressure plate is converted into a force in the horizontal direction during use.

[0017] Beneficial effects:

[0018] 1. The metal material physical properties experimental device, when the device is stretched, the fixture will continue to move closer to the center, so as to reinforce the material, avoid the loose material and cause inaccurate test results, and at the same time effectively reduce the risk during the experiment.

[0019] 2. During the experiment, the metal material physical property experimental device moves downward through the hydraulic device, so that the fixing device fixed on the experimental metal rod moves to both ends. Compared with the unidirectional stretching of the experimental metal rod, the bidirectional stretching of the device is more conducive to making the experimental metal rod evenly stressed, and can more conveniently detect the overall physical properties of the experimental metal rod.

[0028] During the demonstration experiment, the hydraulic device 304 movably connected at the bottom of the supporting device 303 moves downward, driving the side connecting plate 305 and the pressure plate 306 arranged at the bottom of the hydraulic device 304 to move downward. The fixing device 307 drives the fixing device 307 to move outward during the movement, and stretches the experimental metal rod 310 fixed inside the fixing device 307.

When the device is stretched, the fixer 3078 will continuously move closer to the center, thereby reinforcing the material and avoiding loosening of the material and causing inaccurate test results. At the same time, it can also effectively reduce the risks in the experimental process.

Compared with the unidirectional stretching of the experimental metal rod 310, the bidirectional stretching of the device is more conducive to making the experimental metal rod 310 evenly stressed, and can more conveniently detect the overall physical properties of the experimental metal rod 310.
