Vulcanizing machine and center mechanism thereof

Abstract

The invention discloses a center mechanism of a vulcanizing machine. The center mechanism comprises a center tube and an upper chuck used for fixing a capsule upper ring and further comprises an inner clamping ring and an outer clamping ring which are used for fixing a capsule lower ring and a clamping ring locking hydraulic cylinder used for pressing the inner clamping ring and the outer clamping ring, the inner clamping ring and the outer clamping ring are connected in a sleeved mode, and the edge of the capsule lower ring is located between the inner clamping ring and the outer clamping ring. The inner clamping ring and the outer clamping ring are connected in the sleeved mode, the clamping ring locking hydraulic cylinder is utilized for rapidly clamping the capsule lower ring between the inner clamping ring and the outer clamping ring, and therefore the sealing effect is good; compared with threaded connection in the prior art, production efficiency can be effectively improved, operation is easy, and using is reliable. The invention further discloses the vulcanizing machine with the center mechanism.

Description

technical field [0001] The invention relates to the field of tire curing equipment, in particular to a central mechanism of a curing machine. In addition, the present invention also relates to a vulcanizer comprising the above-mentioned central mechanism. Background technique [0002] In the process of tire processing, because the internal microstructure of the tire is a linear polymer before vulcanization, it is a plastic rubber with viscoelasticity, which is easy to deform, low in strength, and has no use value. In order to make it have use value, it needs to be vulcanized. , so that the linear polymer in the plastic rubber undergoes a cross-linking reaction to form a network-like polymer material, which is cured macroscopically. [0003] The vulcanization of the tire is carried out by a vulcanizing machine. For the vulcanizing machine, the central mechanism is one of its most important structures. The central mechanism of the vulcanizing machine in the prior art uses the...

Problems solved by technology

[0004] However, in the prior art, the lower ring of the bladder is sealed and fixed by means of threaded connection, which is not only inefficient, but also takes a long time to install and replace the bladder, and at the same time, the sealing effect is poor, resulting in a decrease in the accuracy of tire vulcanization.
