Abstract

The invention discloses an extending and fixing structure of a tire vulcanizing machine. The extending and fixing structure comprises a bracket assembly and one or more groups of fixture assemblies, wherein the bracket assembly is provided with one or more fixed seats; upper rim fixtures of the fixture assemblies are mounted on the fixed seats; one or more extending base plates are arranged between the upper rim fixtures and the fixed seats of the bracket assembly, and the extending base plates are fixedly connected with the upper rim fixtures; a plurality of threaded holes are respectively formed in the side walls of the extending base plates and the outer walls of the fixed seats; the extending base plates are fixed to the fixed seats through a connection assembly, the connecting assembly comprises a plurality of arc-shaped connecting plates matched with the extending base plates and the outlines of the outer walls of the fixed seats, and a plurality of fixing bolts; the fixing bolts respectively penetrate through the arc-shaped connecting plates to extend into the threaded holes in the side walls of the extending base plates or the threaded holes in the outer walls of the fixed seats. The extending base plates are additionally arranged, so that the distance between the upper rim fixtures and the lower rim fixtures is changed, and different numbers of the extending base plates are needed according to different tire sizes. Therefore, the purpose that the extending fixed structure is suitable for most tire vulcanization operation is achieved.

Description

technical field

[0001] The invention relates to an expanding and fixing structure of a tire vulcanizing machine. Background technique

[0002] During the manufacturing process, tires need to pass through a vulcanizing machine and vulcanized at high temperature in a mold to obtain the designed size, shape, tread pattern and sidewall decoration. After the tire completes the vulcanization cycle and is ejected from the mold, the vulcanization process continues. Due to the special molecular structure of the skeleton material, cotton and polyester will shrink at high temperature and without load, so after vulcanization Cooling process control is an important factor in achieving a product of uniform high quality with the designed size and shape. As one of the most effective ways to effectively control the cooling process of the tire after vulcanization, the tire is post-inflated. After the vulcanization cycle is over, the tire is released from the mold through the tire unloading a...

Examples

Embodiment 1

[0019] Such as Figures 1 to 3 shown

[0020] The expanded fixing structure includes a bracket assembly, four sets of clamp assemblies and a cylinder 6 .

[0021] The bracket assembly includes an upper bracket 11 and a lower bracket 12 , and the air cylinder 6 is arranged between the upper bracket 11 and the lower bracket 12 .

[0022] The upper bracket 11 and the lower bracket 12 are respectively welded with two fixing seats 14, the clamp assembly includes an upper rim clamp 21 and a lower rim clamp 22, the lower rim clamp 22 is welded on the bracket assembly through the fixing base 14, and the upper rim clamp 21 passes through the connecting seat 13 is fixed on the bracket assembly.

[0023] Two expansion backing plates 4 are superimposed on the bottom wall of the fixing seat 14, and the fixing seat 14 and the two expansion backing plates 4 are fixed by connecting components, and each expansion backing plate 4 side wall and the outer wall of the bottom of the fixing seat 1...

Embodiment 2

[0029] Such as Figure 4 shown

[0030] The difference between this embodiment and Embodiment 1 is only that: the number of expansion backing plates 4a in this embodiment is three, the three expansion backing plates 4a are stacked, and the three expansion backing plates 4a are connected by two groups Components are fixed.
