Description

TECHNICAL FIELD

[0001] The utility model belongs to rubber testing technical field especially relates to a single emery wheel double position Akron abrasion testing machine. BACKGROUND

[0002] The abrasion of rubber has been a bottleneck problem restricting the service life of tire. At present, Akron abrasion is still an important means of industry research abrasion. With the progress of rubber technology, special rubber products and the emergence of new Akron samples, many defects of Akron abrasion are exposed. The defects of conventional Akron abrasion tester are mainly the following:

[0003] (1) part of rubber in the later stage of the abrasion process, the sample presents oil-like abrasion surface, sticks to the grinding wheel, reduces the abrasion amount, and the test is invalid, the traditional processing method is to add alumina powder in the abrasion process, but the amount and uniformity of the added alumina powder affect the test, and poor data stability is caused.

[0004] (2) due to different abrasion debris adhered to the surface of the grinding wheel in each test, if the cleaning wheel is used for cleaning after abrasion, the test time will be wasted, and the efficiency will be reduced. If the cleaning wheel is not used for cleaning after abrasion, the abrasion material adhered to the previous sample will affect the next test, so that the abrasion amount changes, and the test result will be affected.

[0005] (3) single station abrasion test, the device can only test one sample at a time, and the test efficiency is low. At present, the traditional Akron test pre-abrasion is 15-20 min, and the formal test is about 100 min, and each sample test takes at least 120 min. Replacing the sample during operation is time-consuming and laborious, and the test cycle is long.

[0006] (4) the Akron test sample is divided into two kinds: adhesive strip type and integral vulcanization type, wherein the adhesive strip type is a traditional sample preparation method, which is pasted on the sample strip on the bottom wheel with a hardness of 75-80HA for testing. The disadvantages of this method are: difficult to prepare, easy to open glue during testing, and easy to fall off. The integral vulcanization type is a new sample: the sample size is directly vulcanized from the rubber material. The disadvantage of this method is: when the hardness is low, the sample is severely deformed, the abrasion amount increases, and the test is affected.

[0007] (5) the traditional equipment lacks effective abrasion material collecting device, and there are many debris around the equipment after the test, which pollutes the test bench table and the equipment.

[0008] The patent CN206192804U discloses a multi-station rubber abrasion testing machine device, and the implementation steps are that a plurality of grinding wheels are used, and the design is equivalent to that a plurality of Akron devices are spliced together to work, and the plurality of abrasion devices work together, so that the test efficiency problem is solved, but since each rubber material and the surface features of the grinding wheel are different, the abrasion is inevitably different even if the test is performed at the same time, and the problems of the sticking grinding wheel and the large data difference of parallel samples are not solved.
