Problems solved by technology

At present, in order to achieve different compressions of rubber samples at the same height, it is necessary to process limiters of different heights, which not only makes the aging test assembly process cumbersome, but also leads to an increase in the processing cost of the limiter.

Abstract

The invention discloses a rubber compression permanent deformation instrument with adjustable compression height. The instrument comprises an upper compression plate, a right limiter, a first reversethread connection block, a first reverse thread locking block, a first threaded rod, a first forward thread locking block, a first forward thread connection block, a left limiter, a lower compressionplate, a second reverse thread connection block, a second reverse thread locking block, a second threaded rod, a second forward thread connection block and a second forward thread locking block. According to the instrument, the limiters at the two sides are close or far away through rotation of the threaded rods with forward and reverse threads on the two ends, so that the compression height of atested sample can be adjusted through the changes of vertical distances of the upper compression plate and the lower compression plate according to actual needs, and the adjusting range is large.

Description

technical field [0001] The invention belongs to the technical field of rubber aging tests, in particular to a rubber compression permanent deformation device with adjustable compression height. Background technique [0002] During the storage and use of rubber products, aging occurs due to the comprehensive influence of various internal and external factors, and the research on the effect on aging is based on the results of aging experiments. Due to the poor controllability of the experimental conditions of natural aging and the long experimental period, the accelerated aging method is usually used in aging experiments to study the change of rubber material properties with aging temperature and aging time. For rubber products that are in a compressed state during actual use, the compression set can effectively reflect its state. Therefore, the test of the compression set of rubber samples after accelerated aging can reasonably evaluate its performance state and predict its a...
