Abnormal shaping drum

Abstract

The invention discloses an abnormal shaping drum consisting of a spindle, a pull rod, an outer slide seat and an inner slide seat sleeved on the spindle, and a drum tile seat, each drum tile seat is correspondingly provided with a straight drum tile and an abnormal drum tile, and two groups of adjacent drum tiles are arranged in wide and narrow, wherein a movable connecting rod is arranged on the drum tile seat at one side of the abnormal drum tile, an I-shaped push disk and a tile nick-filling assembly are sleeved on the spindle; two adjacent drum tile seats have different slope lengths, different initial point positions and different gradients. The abnormal shaping drum has the advantages that the problem of big gap in the shaping drum is solved by using the tile nick-filling assembly; since the two adjacent drum tiles are asynchronous in the stretching process, the limitation that an expanding radius and a constriction radius of the shaping drum cannot be large enough is solved, the production process is simplified and the product quality is improved.

Description

technical field [0001] The present invention relates to a kind of rubber machinery, especially a kind of improvement about the building drum device. Background technique [0002] Generally, the forming drum is cylindrical or cone-shaped. When this type of forming drum is inflated, it is easier to achieve seamless gaps between the tiles. There is a forming drum whose shape is straight in one section and trumpet-shaped in the other. Open, when this shape is formed into a round drum, the gap between the tiles is relatively large, and the tire pressure roller is not solid when the gap is large, which is easy to generate air bubbles, which seriously affects the product quality. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the invention provides a gapless special-shaped forming drum device. [0004] A special-shaped forming drum, the device includes a main shaft, a pull rod, an outer sliding seat and an inner sliding seat sleeved on...

[0002] Generally, the forming drum is cylindrical or cone-shaped. When this type of forming drum is inflated, it is easier to achieve seamless gaps between the tiles. There is a forming drum whose shape is straight in one section and trumpet-shaped in the other. Open, when this shape is formed into a round shape, the gap between the tiles is relatively large, and the large blank tire pressure roller in the gap is not solid, which is easy to produce air bubbles, which seriously affects the product quality.
