Problems solved by technology

Foreign companies such as MTS and Instron also have creep testing machines specially used for elastic components. They mainly use electronic control and electric drive precision screw loading, and the test results are also very good, but the purchase price of these testing machines is very high. Expensive, requires a lot of investment, and because they are all loaded by electric control, there is also the possibility that if the test is powered off, the entire test will fail. However, under the current power supply situation in our country, power outages are often possible. occurring

Embodiment Construction

[0014] The accompanying drawings show a specific embodiment of the present invention, and the present invention will be further described in detail below in conjunction with the accompanying drawings. It can be seen from the attached drawings that this elastic body creep testing machine includes frame 6, test box 8, creep test loading mechanism 12, and its feature is: the creep test is combined by a lever and weight The mechanical device is loaded for the creep test. The loading mechanism 12 is a composite mechanical loading structure combined with a loading lever 2 and a weight 10. The creep test is loaded by the weight 10 to the loading lever 2, and then the loading lever 2 passes the loading force through The loading point 13 is transmitted to the adjustable guide rod 4, and the adjustable guide rod 4 loads the creep specimen. The specific structure is: a high and low temperature experiment box 8 is placed on the base 14 of the rack, a test sample is placed in the high and low ...

Abstract

In the present invention, a hinging point of lever is set on framework, one end of lever crossbeam is connected to hinging point and its loading crossbeam can be swung upwards and downwards around framework hinge, another end of lever is hinged with loading weight which is hinged on lever crossbeam through a movable block set and wirerope, movable block set can be two set, another loading application point between hinging point and weight hinged point is on lever crossbeam, adjustable guide bar is connected to loading application point and loading force from weight loading is applied to test sample through adjustable guide bar.

Description

[0001] Field [0002] The present invention is a static test method and device, which belongs to a test method and device for testing or analyzing material characteristics by measuring the chemical or physical properties of the material, in particular, it refers to testing the creep fatigue resistance of elastic elements The test method and device. It is mainly used for compression or shear creep test of elastic elements. Background technique [0003] At present, many domestic manufacturers use hydraulic servo test system to conduct the creep test of elastic components. Due to the particularity of the creep test, it is difficult to guarantee the accuracy of hydraulic servo control, the load sometimes fluctuates, and the test results are not very satisfactory. The operating cost is high and the economic benefits are poor. There are also manufacturers that use electronic universal testing machines for creep experiments, but electronic universal testing machines are easily affected by...
