Embodiment

[0038] Such as Figure 1~Figure 4 As shown, a tensile device for testing rubber swelling characteristics described in this embodiment includes a frame body, a moving plate 4 arranged in the frame, and a rotating mechanism that drives the moving plate 4 to move back and forth, the frame body and the moving plate 4 is correspondingly provided with a first clamping mechanism and a second clamping mechanism for respectively clamping two ends of the rubber.

[0039] Specifically, the rotating mechanism of this embodiment can be realized by adopting the following structure: the rotating mechanism includes a screw rod 5 and a rotating handle 11, one end of the screw rod 5 is rotatably fixed on the moving plate 4, and the other end is fixedly connected with the rotating handle 11, and The screw rod 5 is threadedly engaged with the frame body.

[0040] The frame body of this embodiment includes two parallel guide plates 1, an upper static plate 2 and a lower static plate 3, and a guid...

Abstract

The invention discloses a stretching device for rubber swelling property testing and a testing method. The stretching device comprises a frame, a movable plate arranged in the frame, and a rotating mechanism for driving the movable plate to move back and forth. A first clamping mechanism and a second clamping mechanism for clamping the two ends of rubber respectively are correspondingly arranged on the frame and the movable plate. By means of the structure, the position of the movable plate is regulated through the rotating mechanism, and then the distance between the first clamping mechanism and the second clamping mechanism is adjusted to obtain the stretching amount and deformation amount needed by the rubber. Due to the fact that the frame is adopted for restraining the movement locus of the movable plate, the movement stability and reliability of the movable plate are guaranteed, and the reliability of rubber swelling testing data is ensured.

Description

technical field [0001] The invention relates to the field of testing rubber properties, in particular to a stretching device and a testing method for testing rubber swelling properties. Background technique [0002] Rubber is widely used in all aspects of industry and life because of its good insulation, elasticity, high and low temperature resistance, etc. Then, these rubbers inevitably coexist with some organic solvents for a long time in the application, because the organic solvents can cause the rubber to swell, thereby affecting its performance. Rubber is often in a stretched state during application, and stretching deformation will affect the swelling behavior of rubber in organic solvents. Therefore, it is necessary to measure the swelling between the stretched rubber and the organic solvent to evaluate the coordination and applicability of the rubber or the solvent. [0003] With the development of the power industry, cables and cable accessories have been widely u...
