Design and Static Analysis of Rotary Manipulator for Fixed-point Tire Vulcanization

The fixed-point vulcanization can be used to reduce the defects in the tire vulcanization for the green tire and the adverse impacts on the uniformity and dynamic balance of the finished tire. In order to implement the fixed-point vulcanization of the green tire and improve the uniformity and dynamic balance of the tire, the dual-cylinder rotary manipulator is designed for fixed-point tire vulcanization using Siemens NX software. The rotary cylinder drives the gripping mechanism to rotate and identify code of the green tire and then locates the circumferential position of the green tire. The piston cylinder drives the manipulator claws and make a telescopic movement to grip or release the green tire. The structure static analyses on the key components such as bolts, horizontal adjustment joints, connecting arms and guide pillars of the manipulator are carried out using ABAQUS software. The simulation results show that the designed manipulator meets the requirements of strength and accuracy.
