All-steel four-drum engineering tire single stage building machine

Abstract

The invention discloses an all-steel four-drum engineering tire single stage building machine, which includes a belt layer drum area, a drum building area, a drum winding area and a tire body laminating drum area. The drum building area and the tire body laminating area are arranged on the left side and the right side of a tire body transfer ring base in the horizontal direction, the belt layer drum area and the drum winding area are arranged on the front side and the rear side of the drum building area in the vertical direction, a green tire transfer ring cross beam and a belt layer transferring cross beam are arranged overhead between the drum building area and the tire body laminating drum area in the vertical direction, the tire body transfer ring base is provided with a tire body transfer ring, a green tire transfer ring is hung on the green tire transfer ring cross beam, and a belt layer transfer ring is hung on the belt layer transfer ring cross beam. According to the all-steelfour-drum engineering tire single stage building machine, the disadvantages of horizontal layout of rotary four-building machines are overcome, equipment floor area is greatly decreased, the movementof the tire body transfer ring, the overhead belt layer transfer ring and the overhead green tire transfer ring does not overlap, and the positioning accuracy and the production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of tire building machines, in particular to an all-steel four-drum engineering tire one-shot building machine. Background technique [0002] In recent years, with the increasing demand for off-road tires, especially the hot market for small and medium-sized off-road tires, the production efficiency of conventional off-road tire building machines is difficult to meet the needs of orders. [0003] For the molding of small and medium-sized all-steel OTR tires, most of them currently use the one-shot molding process on the market. Commonly used molding machines include two-drum OTR tire building machines and rotary four-drum OTR tire building machines. The four drums of the rotary four-drum OTR tire building machine are arranged in a row, two of which can rotate half a circle, the left drum is used for tire molding, and the right drum is used for tire tread winding . Tire building and tread winding are two for...

AI Technical Summary

Problems solved by technology

Tire building and tread winding are two forming processes. The production sequence of tire building and tread extrusion and winding of the two building drums conflicts. The building drum on the left can only position the carcass cylinder after the tire embryo on the right is wrapped. The process must be completed in one of the time sequences before the next process can be carried out. The idle rate of the forming drum is high, the production efficiency is low, and the utilization rate of the forming machine is extremely low. The layout is arranged side by side, which occupies a large area and the equipment cost is high.
