Rubber specimen apparatus for crack resistance test

摘要

The present invention relates to a test apparatus for evaluating aging according to cracking of rubber specimens, in particular, by applying an hourglass type rubber specimen in which the trapezoidal shape is positioned up and down in dynamic and static state, and crack resistance according to various strains. It relates to a rubber specimen test apparatus for evaluating cracks. To this end, the present invention provides upper and lower supporters 2a and 2b for fixing both front ends of the hourglass rubber specimen 1, and upper and lower connecting bars 3a and 3b for fixing the upper and lower supporters 2a and 2b. A fixing table 4 fixedly mounted to the upper connecting table 3a, a moving table 5 fixedly mounted to the lower connecting table 3b, and connected between the fixing table 4 and the moving table 5 Both guide beams 6 for guiding the vertical movement of (5), a base table 7 to which both guide beams 6 are connected and fixed, and installed on the base table 7 to move the movable table 5. It consists of the moving screw shaft 8 which reciprocates.
