Description

Technical Field

[0001] The utility model relates to the technical field of radial tire building drums, in particular to a radial tire building drum with adjustable outer diameter. Background Art

[0002] The building drum is one of the key equipment in the radial tire production process. It is responsible for providing the necessary profile to form the outer diameter and sidewall of the tire. Traditional building drums are often fixed in outer diameter size, which requires manufacturers to prepare multiple sets of equipment for different tire specifications.

[0003] The main problems caused by traditional fixed outer diameter drums are high cost and poor flexibility. Each specification of tire requires a specific set of drums, which increases the number of production equipment and storage space, and the entire set of equipment needs to be replaced when switching production, which is time-consuming and labor-intensive. In order to solve the above problems, some manufacturers have begun to develop building drums with adjustable outer diameters. This type of equipment allows the operator to adjust the outer diameter of the drum within a certain range through various mechanical or hydraulic systems to adapt to the production of tires of different specifications. Although these systems improve the flexibility of the equipment, they may still have problems such as limited adjustment range, complex operation or high cost. Utility Model Content
