Description

All-steel light-clamping sector block capsule of three-drum forming machine Technical Field The utility model belongs to the field of tire manufacturing, and particularly relates to an all-steel light-truck sector block capsule of a three-drum forming machine. Background At present, the forming machine for producing all-steel light truck radial tires at home is mainly a three-drum forming machine, and is widely applied due to the characteristics of low maintenance cost, high production efficiency and the like. The three-drum forming machine has more production specifications, including 16 inches, 17.5 inches and the like, wherein the 16 inches is provided with 7.50R16 and 8.25R16 inches, and when 7.50R16 products are produced on site, the problems of bead edge emergence, bead opening upper extraction and the like occur, the three-drum forming machine is usually adjusted through a construction structure, a whole circle of pits appear on a tire blank opening after construction adjustment, and the problem of bead gum shortage occurs after vulcanization, so that the quality of finished tires is seriously affected. The tire bead opening produced by the two-drum light-clamp forming machine is full, the tire bead opening produced by the three-drum forming machine is obviously narrowed, the structure of the forming machine is analyzed from the forming machine, the fan-shaped block structure of the forming machine is the same, and the curve and the angle of the bottom of a 16-inch capsule of the three-drum forming machine are unreasonable from the capsule curve analysis. Disclosure of utility model The utility model aims to provide a novel all-steel light-clip radial tire sector block capsule, which can effectively solve the problems of full bead pits and tire bead gum shortage after vulcanization in 7.50R16 specification in the production process and improve the quality of finished tires. In order to achieve the above purpose, the utility model adopts the following technical scheme: The novel all-steel light-weight tire-noon fan-shaped block capsule comprises a capsule body, one side of the capsule body is a capsule outer edge, the other side corresponding to the capsule outer edge is a capsule inner edge, a part between the capsule body inner edge and the capsule outer edge and in contact with a forming drum fan-shaped block is a capsule bottom, a part between the capsule body inner edge and the capsule outer edge corresponding to the capsule bottom is a capsule top, a capsule tail is arranged between the capsule top and the capsule outer edge, a capsule gradient a is arranged at the capsule top, and the capsule gradient a is 10 degrees. The contact part between the top of the capsule and the outer edge is the top radian, and the top radian is R5. The top of the capsule is in smooth arc transitional connection with the tail of the capsule. Compared with the prior art, the utility model has the beneficial effects that: 1. the slope of capsule top reduces, increases the steel ring and effectively sits the width, avoids the steel ring landing to be outside. 2. The radian of the top of the capsule is close to the angle of the outer edge of the hexagonal steel ring, so that the steel ring is tightly attached to the capsule. 3. The tail of the capsule is added with radian, so that the steel ring is completely located at the bottom of the capsule. Drawings Figure 1 is a schematic illustration of the cooperation of the capsule of the present utility model with a steel rim. Fig. 2 is a view showing the state of use of the capsule of the present utility model. Fig. 3 is a schematic diagram (1) of the cooperation of the original capsule and the steel ring. Fig. 4 is a schematic diagram (2) of the cooperation of the original capsule and the steel ring. The capsule comprises a capsule body 1, a capsule outer edge 11, a capsule inner edge 12, a capsule top 13, a capsule top 131, a capsule bottom 14, a capsule tail 15, a forming drum sector block 2, a steel ring 3 and a forming drum anti-wrapping pinch roller 4.
