Abstract
The utility model relates to a vulcanization mould utensil of engineering machine tool tire bead portion quality inspection belongs to tire production mould field. The tire bead part vulcanizing machine is provided with a vulcanizing mold steel ring, a circumferential U-shaped groove is processed on a platform of the vulcanizing mold steel ring, the depth of the U-shaped groove is 0.6mm, the width of the U-shaped groove is 0.8mm, the U-shaped groove is positioned at the position of 80% -85% of the design width of a tire bead, and if the circumferential direction of the platform part of a vulcanized finished tire bead opening is provided with a raised identification line, the tire bead part of the engineering machinery tire can be judged to be unqualified if incomplete. Use the utility model discloses the tire of producing can effectively discern and control the unusual condition of engineering tire bead portion material distribution, prevents that the engineering tire flow of early failure from appearing in the bead portion from to market.
Description
Technical Field
The utility model belongs to tire mold field says in detail a vulcanization mould utensil of engineering machine tool tire bead portion quality inspection.
Background
As is known, the prior mining engineering tire has the problems of early empty tire and quality loss, but the capability of checking the quality conformity of the tire bead part is insufficient, and the abnormal distribution of the material of the bead part cannot be effectively identified and controlled, so that the early failure of the engineering tire bead part in the market is caused.
Disclosure of Invention
In order to overcome the not enough of prior art, the utility model provides a vulcanizing mould of engineering machine tire bead portion quality inspection can effectively discern and control the unusual condition of engineering tire bead portion material distribution.
The utility model provides a technical scheme that its technical problem adopted is: a vulcanization mould for quality inspection of a bead part of an engineering machinery tire is provided with a vulcanization mould steel ring and is characterized in that a circumferential U-shaped groove is processed on a platform of the vulcanization mould steel ring, and the depth and the width of the U-shaped groove are 0.6mm and 0.8mm respectively.
The beneficial effects of the utility model are that, the engineering tire of production can effectively discern and control the unusual condition of tire bead portion material distribution, prevents that the engineering tire that early inefficacy from appearing in the bead portion from flowing to market.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is the local schematic diagram of the steel ring platform of the vulcanizing mold of the present invention.
In the figure, 1, a vulcanization mould steel ring and 2.U-shaped grooves are arranged.
Detailed Description
In the figure, the utility model discloses be equipped with curing mould steel ring 1, process the U type groove 2 of a circumference on curing mould steel ring 1's platform, the degree of depth 0.6mm, width 0.8mm, the position in U type groove 2 is bead design width 80% -85% position, use the circumference at the finished product child mouth platform position that curing mould steel ring 1 vulcanizes out has a bellied sign line, if finished product child mouth platform width narrows down, the incomplete lack of sign line circumference incomplete, can think engineering machine tool tire bead portion unqualified directly perceivedly.
When the mold is used for producing the engineering machinery tire, the following method can be matched and used when judging whether the tire is qualified or not:
according to the design requirements of the total thickness of the assembly line part and the total thickness of the tire bead part, namely-2 mm to +4 mm, the total thickness of the assembly line part and the total thickness of the tire bead part of the qualified engineering machinery tire bead are set, then a caliper gauge is used for detecting the total thickness of the assembly line part and the total thickness of the tire bead part, when the caliper gauge is used for measuring the total thickness of the tire assembly line part and the total thickness of the tire bead part, the distribution measurement is carried out according to points in a single-side circumferential 90-degree angle, and the design is sequentially marked as follows: A. b, C, D, E, F, G and H, points in the angle of 90 degrees in the circumferential direction on the other side are marked as A1, B1, C1, D1, E1, F1, G1 and H1, the measured result is recorded and compared with the total thickness of the assembly line part and the total thickness standard of the bead part, and if the total thickness of the assembly line part and the total thickness standard of the bead part are exceeded, the quality of the bead part of the engineering machinery tire is determined to be unqualified.
According to the design requirement of the thickness of the bead heel part rubber and the thickness of the bead bottom rubber of the engineering machinery tire, the bead heel part rubber thickness and the bead bottom rubber thickness standard of the bead of the qualified engineering machinery tire are set, then a PHYNIX thickness gauge is used for detecting the bead heel part rubber thickness and the bead bottom rubber thickness, when the bead heel part rubber thickness and the bead bottom rubber thickness are measured by the PHYNIX thickness gauge, the bead heel part rubber thickness and the bead bottom rubber thickness are distributed and measured according to points in a single-side circumferential 90-degree angle, and the measurement points are staggered by 45-degree angles with the measurement points of the total thickness of the bead part, and the measurement points are sequentially marked as: I. j, K, L, M, N, O and P, wherein points in the circumferential direction of the other side within 90 degrees are marked as I1, J1, K1, L1, M1, N1, O1 and P1, the measured result is recorded and compared with the bead heel part rubber thickness and bead bottom rubber thickness standard, and if the bead heel part rubber thickness and bead bottom rubber thickness standard are exceeded, the quality of the bead part of the engineering machinery tire is determined to be unqualified.
