Embodiment Construction

[0012] The step that the present invention implements operation is:

[0013] 1. In figure 1 , figure 2 , image 3 In the embodiment, the Figure 4 Place the vulcanized tire tread pattern vulcanized rubber sample (4) on the corresponding notch of the base of the workbench (3), and use Figure 5 Fasten the gland (5) in the workbench (3), then install the workbench (3) on the support frame (1), and use two pins (2) to position it symmetrically. which is figure 1 , figure 2 , image 3 Status location shown.

[0014] 2. On the tire static load testing machine, the Image 6 Install the indenter (6) on its chuck, move the overall tooling completed in step 1 to the working position of the testing machine, adjust the force measuring device and loading device of the testing machine according to the operating requirements of the testing machine, and start the testing machine , the indenter (6) moves downward slowly, and stops when the indenter (6) advances to its front end and...

Abstract

The invention provides an apparatus applicable to apparatus applicable to contrast detection of destructive characteristics of tire tread patterns. According to the invention, different tire tread pattern rubber samples (4) are fixed on a workbench (3) via a gland (5) and are assembled on a bracing frame (1) via pins (2); then plunger testing with a static load testing machine for tires is carriedout in virtue of pressure heads (6) of different shapes so as to detect plunger energy bearable by the different tire tread pattern vulcanized-rubber samples (4) and the stroke parameters of the vulcanized-rubber samples (4); and puncture resistance, pricking resistance, cutting resistance, pattern-spalling resistance and other usage performances of rubber prepared according to different formulasare compared and fed back according to different parameter values. The detection apparatus is used for contrast detection of the performance of tire tread pattern rubber; the detection object of theapparatus is vulcanized rubber for tire tread patterns instead of finished tires, so the apparatus well targets to defects and can realize timely feedback and improvement of a formula system for tiretread patterns in the designing phase of a product; and the apparatus is applicable to designing departments, experimental and detection departments and other departments of tire manufacturers.

Description

technical field [0001] The invention relates to a test device for contrast detection of tire tread pattern destruction performance. The detection device is used for contrast detection of tire tread pattern destruction performance and can be used by design, experimental detection and other departments of tire manufacturing plants. Background technique [0002] For ordinary structure tires, the tread is the most severe component that bears the external stress, and is the main damaged part of the tire being scrapped. There are two main forms of damage: one is normal tread wear to wear marks, and the other is abnormal tread pattern trauma—such as pattern block punctures, punctures, cuts, peeling and other defects, and then Cause early damage and be scrapped, so tire treads should avoid these traumas. The tire tread must have good performance such as anti-puncture and anti-pattern peeling. The performance involved in this part is usually mainly through the road test of the finis...
