Problems solved by technology

In the current all-steel radial tire building drum, there are existing mechanical turn-up forming drums, such as "a mechanical forming drum" (patent No. 01269962.4), "conical oblique wedge slider type building drum" (patent No. 200320110467.9), "A tire metal forming drum" (Patent No. 200320103041.0)", etc., there are discontinuities on the turn-up circumference, uneven turn-up force, deep indentation, inaccurate material distribution position, inconsistent height of sidewall turn-up, and many bubbles , Difficult to adjust during work, poor stability, complex structure, high price, heavy weight, high energy consumption, etc.; The package is not in place, the quality of the turn-up is unstable, the pass rate of the dynamic balance test is low, and the labor intensity is high, and the production efficiency is low; therefore, it is necessary to provide a new type of all-steel radial tire turn-up forming drum with better performance.

Abstract

The invention relates to a machine boost assembly drum of a radial ply reversed-packaging tire mold, which comprises a principal axis (1), a ballscrew pair (2), a longitudinal key (3), a supporting sleeve (4), a boost cylinder (5), a boost cylinder rod (6), a boost connecting bar (7), a boost plate (8), a wedge (9), a fan-shaped segment cylinder (10), a fan-shaped segment piston (11), a reversed-packaging mold (12), an adhesive tape (13), a fan-shaped segment (14), a tire shoulder cylinder body (15), a locating disc (16), an outer barrel (17), a middle barrel (18), a center panel (19), an inner barrel (20), an inner barrel flange (21) and the like. The boost connecting bar (7) is respectively connected with the boost plate (8) and the boost cylinder rod (6) which are evenly distributed along the circumference by a gemel pair in a mechanical way; the boost plate (8) is connected with the wedge (9) by the gemel pair in a mechanical way; meanwhile, an inner sleeve of the middle drum of the tyre assembly drum is formed by connecting and assembling the inner sleeve (20) of an outer thread and the inner sleeve flange of an inner thread with a thread. The invention has the advantages of little stretching of the reversed packaging of the sidewall, more uniform distribution of glue stuff and good quality of the reversed packaging, and the like; besides, the inner sleeve of the middle drum of the assembly drum can be dismantled and maintained conveniently.

Description

technical field [0001] The invention relates to an all-steel radial tire capsule turn-up forming drum, in particular to provide a novel radial tire capsule turn-up mechanically boosted forming drum for rubber product molding preparation and technology. technical background [0002] The all-steel radial tire building drum is the executive mechanism of tire building, which affects the accuracy of the material distribution of each part of the formed tire blank, plays an extremely important role in the durability of the tire, and directly affects the tire building quality. In the current all-steel radial tire building drum, there are existing mechanical turn-up forming drums, such as "a mechanical forming drum" (patent No. 01269962.4), "conical oblique wedge slider type building drum" (patent No. 200320110467.9), "A tire metal forming drum" (Patent No. 200320103041.0)", etc., there are discontinuities on the turn-up circumference, uneven turn-up force, deep indentation, inaccura...
