Further, it is spaced 45 ° between described adjacent fan-shaped projection.
This utility model compared with prior art, has the advantage that
(1) this utility model shortens sample length, and the almost all kinds of any degree of depth of finished product tire can be sampled detection, expands the range that Akron abrasion is measured；
(2) this utility model can expand to finished product tire conditions of vulcanization, tread rubber ageing-resistant performance, the amendment etc. of different regions formula are provided data basis by the range of application of Akron abrasion from the anti-wear performance of single judgment experiment glue；
(3) this utility model is with low cost, simple to operate, the testing time is short, data are accurate, it is only necessary to conventional Akron test machine i.e. can complete detection；
(4) the fan-shaped projection above the rubber tire that test device described in the utility model uses can be adjusted according to the finished product tire of different pattern block sizes, thus the finished product tire of different model is set up the company standard about Akron abrasion, enterprise-quality management and control is provided foundation；
(5) different regions can be simulated when using test device to test described in the utility model, the true temperature used under environment and humidity, more press close to finished product tire and truly use environment, therefore gained Akron test data more closing to reality.
Accompanying drawing explanation
Fig. 1 is the structural representation of test device described in the utility model.
Fig. 2 is that batten is bonded to test the schematic diagram on device.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As it is shown in figure 1, the device of test finished product tire tread glue Akron abrasion described in the utility model, including rubber tire 1, the outline of rubber tire 1 is circular, and a diameter of 6.8cm of rubber tire 1, the thickness of rubber tire 1 is 12.7mm ± 0.2mm；Arranging one fan-shaped protruding 2 every 45 ° on the rounded outer profiles of described rubber tire 1, form groove 4 between adjacent fan-shaped protruding 2, the fan-shaped height of protruding 2 is 1.6mm；The hardness of described rubber tire 1 is 75 degree ~ 80 degree (Shao Er A), and the center of rubber tire 1 is provided with centre bore 3, and centre bore 3 diameter is consistent with the diameter of rubber tire gyroaxis.
The method of described test finished product tire tread glue Akron abrasion, comprises the following steps:
(1) tread rubber sampling: can obtain in any degree of depth of pattern block during the sampling of finished product tire, and grinder buffing 15 ~ 20min makes spline surfaces consistency of thickness, when ensureing test, Akron abrasion machine will not cause vibration because of uneven thickness, and a length of 3.88cm of batten, thickness are 3.2mm, width is 12.7mm；Carry out contrast test if desired for experiment glue or elastomeric compound, grinding tool can be used to prepare sample according to GB/T1689-1998 requirement, then be cut to length 3.88cm；
(2) as in figure 2 it is shown, be bonded to by batten in the groove 4 of rubber tire 1, groove 4 can prevent batten from skidding occur when testing, and during bonding, batten should not be restricted by tension force, can not be by the extruding of both sides sector projection 2；
(3) testing according to GB/T1689-1998 method, during test, the angle between caster axle and grinding wheel spindle is 25 ° ± 0.5 °, when batten travels the wear volume of 1.61km relatively greatly, uses the inclination angle of 15 ° ± 0.5 ° to measure.
This utility model has the advantage that
