Such machines include tire building machines, tire bead ring machines, tire shaping vulcanizers, capsule vulcanizers, pad vulcanizers, inner tube jointers and inner tube vulcanizers, as well as force tire machinery, tire reconditioning machines and reclaimed rubber production machines. More than 60% of the world's rubber is used to make tires, so tire machinery plays an important role in rubber machinery. Figure 2 is a tire production process.
A green tire used to laminate various components such as rubberized curtains, bead rings, and treads into tires. Divided into two categories according to the use of ordinary tire forming machine and radial tire forming machine. Tire cords of common tire casing cords are inclined at an angle. During molding, the fabric drums are put on the forming drums first, and then the wire loops are laid on both sides, and the buffer layer and the tread rubber are covered in the middle to form the tires. The billet becomes a tube. The main difference between radial tires and ordinary tires in terms of structure is that the buffer layer cords are 90° to 75° (nearly orthogonal) to the carcass axis, so the diameter size of the buffer layer after forming cannot be changed greatly, so the carcass is made of Afterwards, it needs to expand to a shape that is approximately fixed, and then attaches a buffer layer. Therefore, the structure of the radial tire building machine is also different from the ordinary tire building machine.
