Problems solved by technology

At present, the drum plates of various forming drums on the market are all made of metal materials, such as steel, aluminum alloy, etc. These metal drum plates with relatively high density are heavy, resulting in the heavy weight of the entire circle of drum plates supported by the radial support of the forming drum. In turn, the load on the main shaft is relatively large. For example, the internal support members radially push the drum board to expand and contract. The weight of the drum board and the pressure on the formed tire are all loaded on the main shaft. The service life is reduced, and when the main shaft drives the entire forming drum to rotate, the heavy metal drum plate will form a large centrifugal force and load on the main shaft, and the drum plate will generate a huge inertial torque during the process of forming the drum from rotating to braking. , and loaded on the main shaft through the internal support, therefore, the requirement on the main shaft load is extremely high, which greatly increases the manufacturing cost and maintenance cost of the tire building machine

Abstract

The invention provides a tire forming drum with an improved structure. The tire forming drum with the improved structure comprises a main shaft, and circular ring-shaped side plates arranged on two sides of the main shaft, wherein a plurality of arc-shaped drum plates are arranged around circumferential directions of the side plates; multiple groups of telescopic devices for driving the drum plates to radially move in a reciprocating way are arranged on the main shaft between the two side plate; each drum plate is formed by radially stacking and fixedly connecting an inner layer plate and an outer layer plate; and the inner layer plates and the outer layer plates are formed by aluminum honeycomb plates and carbon fiber cloth wrapped, cured and adhered to the surfaces of the aluminum honeycomb plates. Since the drum plate parts are made of the aluminum honeycomb plates and the carbon fiber cloth, the weight of the drum plates is greatly reduced, the forming quality of a tire blank cannot be influenced, and the stress size of the main shaft is reduced, so that the manufacturing cost and the maintenance cost of the main shaft can be reduced, and the tire production cost is further reduced.

Description

technical field [0001] The invention relates to a building drum for a tire building machine, in particular to a tire building drum with improved structure. Background technique [0002] The tire building drum installed on the tire building machine is an important part in tire building. Its main function is to compound various rubber materials and form them into tire blanks. The tire building drum is mainly composed of inner supports and outer drum plates. The inner supports are used to support the drum plates and drive the drum plates to expand and contract. Several drum plates form a drum surface for laminating various Compound and tire blank molding. At present, the drum plates of various forming drums on the market are all made of metal materials, such as steel, aluminum alloy, etc. These metal drum plates with relatively high density are heavy, resulting in the heavy weight of the entire circle of drum plates supported by the radial support of the forming drum. In turn...
