Embodiment

[0034] Such as Figure 1-6 As shown, the embodiment of the present invention provides a constant load metal tensile test device, including a base 1, the upper end of the base 1 is fixedly connected with a frame 2, and the front profile of the frame 2 is "Π", without affecting other structures on the frame 2 In the case of the position, ribs can be added at the corners of the frame 2 to improve the structural strength of the frame 2. The inside of the frame 2 is provided with a slider 11, and one side of the slider 11 is rotatably connected to a lever 6, and the lever One end of 6 is provided with a negative pressure device 7, which provides a constant load in the form of atmospheric pressure, and the final force acting on the metal material can be changed by using the lever 6 to realize the setting of the specified load, and the atmospheric pressure will change with time and region. The force generated by the negative pressure device 7 will also change, so the lever 6 can be u...

Abstract

The invention provides a constant load metal tensile test device, which relates to the field of metal tensile tests. The constant load metal tensile test device comprises a base, the upper end of the base is fixedly connected with a frame, the inside of the frame is provided with a slider, one side of the slider is rotatably connected with a lever, and the lever is One end is provided with a negative pressure device, the upper end of the negative pressure device is connected with the frame, the lower end of the negative pressure device is rotatably connected with one end of the lever, and the other end of the lever is rotatably connected with a fixing piece, and the fixing piece A second screw rod is arranged above, the second screw rod penetrates the frame, the lower end of the second screw rod is fixedly connected with a fixing member, and a clamping member is arranged at a turning point between the slider and the lever. By using atmospheric pressure to generate a constant load, and using the principle of leverage to change the magnitude of the force, the device can be miniaturized.

Description

technical field [0001] The invention relates to the technical field of metal tensile testing, in particular to a constant load metal tensile testing device. Background technique [0002] Tensile testing refers to a test method for determining the properties of a material under an axial tensile load. The data obtained from the tensile test can determine the elastic limit, elongation, elastic modulus, proportional limit, area reduction, tensile strength, yield point, yield strength and other tensile performance indicators of the material. In the research of materials, it is necessary to test the properties of new materials in real time, and tensile testing is usually a means to determine the properties of materials. There are several types of devices for performing constant load tensile tests on existing metal materials. [0003] A tensile test is carried out on metal materials by means of screw, hydraulic pressure, air pressure, etc. In the experiment, a pressure sensor is ...
