Problems solved by technology
Rubber has many characteristics, and the relative rigidity at low temperature is one of the important characteristics. However, there is currently no molding device in the market that can test the relative rigidity of rubber at low temperature. Therefore, the relative rigidity of rubber Testing brings inconvenience, which reduces the efficiency of testing and greatly increases the cost of testing

The invention provides a Gehman torsion testing machine, which can test the rigidity characteristic of rubber at a low temperature. The testing machine comprises a frame, and a low temperature box and a guiding column are arranged on the frame; an elevating plate is arranged on the guiding column, a transmission shaft is arranged on the elevating plate, one end of the transmission shaft is connected to a step motor, the other end of the transmission shaft is connected to an upper synchronizing wheel; the upper synchronizing wheel is connected to the upper end of a synchronizing shaft through an upper synchronizing belt, the lower end of the synchronizing shaft is connected to a lower synchronizing wheel through a lower synchronizing belt; the lower end of the lower synchronizing wheel is connected to a torsion head shaft; the torsion head shaft is connected to a rotation rod, the rotation rod is provided with a round magnetic grid, the round magnetic grid is provided with a round magnetic grid reading head, the transmission rod is also provided with an upper holder and a lower holder, and a sample is tested in the low temperature box. The provided testing machine can carry out relative rigidity characteristic tests on a plurality of rubber samples at a low temperature, the test results are accurate and reliable, moreover, the test efficiency is high, the structure of the testing machine is simple, and thus the test cost is largely reduced.
Description
technical field [0001] The invention relates to a testing machine, in particular to a Jimen torsion testing machine. Background technique [0002] Rubber is latex taken from plants such as rubber trees and rubber grasses. After processing, it has the characteristics of elasticity, insulation, impermeability and air. Rubber products are widely used in industry or in all aspects of life. Rubber has many characteristics, and the relative rigidity at low temperature is one of the important characteristics. However, there is currently no molding device in the market that can test the relative rigidity of rubber at low temperature. Therefore, the relative rigidity of rubber Testing brings inconvenience, thereby reducing the efficiency of testing, and greatly increasing the cost of testing. It is used to test the relative rigidity of rubber in a low temperature environment, also known as the Jimen test. [0003] If there is a device that can realize high-efficiency Guimen test, i...
