Dual-mode high-efficiency bias tire automatic vulcanizing machine

Abstract

The invention discloses a dual-mold high-efficiency oblique-crossing full-automatic tire vulcanizing machine. The full-automatic tire vulcanizing machine comprises an electric control system, an atmosphere chamber hot plate, a main frame, an upper clamping disc, a lower clamping disc, an upper mold, a lower mold, a central mechanism, a main oil cylinder, a hydraulic system and a thermotechnical system and also comprises an upper-mold lifting mechanism, wherein the upper-mold lifting mechanism consists of an oil cylinder and guide shafts; the guide shafts are arranged at two sides of the main frame and are in sliding and matching connection with the upper mold; the oil cylinder is fixedly connected with the upper mold; the upper-mold lifting mechanism is arranged on the main frame and the guide shafts at two sides are driven to move up and down by an upper oil cylinder and a lower oil cylinder at the middle part; when a tire is installed on the upper mold, the oil cylinder of the lifting mechanism falls to the lower-end position, so that the distance between the upper mold and the lower mold for installing the tire is greatly increased, further the tire can be conveniently arranged into a tire blank; when the tire is installed in the lower mold, the oil cylinder of the lifting mechanism rises to the upper-end position, so that the distance of the upper mold and the lower mold for installing the tire is also increased, further the tire can be conveniently arranged in the tire blank; the upper-mold lifting mechanism plays a main role in increasing the tire installing distance of the upper mold and the lower mold, so that the height of the rack is greatly reduced and the convenience is brought for operation.

Description

Technical field [0001] The invention relates to a double-mode high-efficiency bias tire automatic vulcanizing machine, which belongs to the technical field of rubber vulcanization machinery. Background technique [0002] With the rapid development of my country's transportation industry, the continuous paving of highways has put forward higher and higher requirements for the uniformity of automobile tires, so the requirements for the working accuracy of the vulcanizer have also increased. When the hydraulic vulcanizer is working, the lifting cylinder drives the upper mold to rise along the guide column, forming a cavity in the frame, and the tyre-loading device is transferred to the tyre, the upper and lower rings of the center mechanism rise, the tire blank is positioned, and the tyre-loading device exits after unloading the tire , The lifting cylinder drives the upper mold to descend along the guide column to close the mold. After the tire blank is shaped, the mold is clamped i...

AI Technical Summary

Problems solved by technology

[0003] 1. The vulcanizing machine does not have a tire storage device, which makes it difficult for workers to take and release tires and affects production efficiency;

[0004] 2. Bias tire vulcanizing machines do not contain the tire loading mechanism, but generally adopt the method of manually placing the tire blank. Manually placing the tire blank will cause misalignment and pressure deviation of the vulcanized tire.

[0006] 4. Most of the vulcanizers of this type are directly welded by section steel, which produces a large amount of welding stress to reduce the strength of the frame, and the thermal stress generated during the welding process makes the frame distorted and deformed, which greatly affects the performance of the vulcanizer.

[0007] 5. The opening distance of all vulcanizing machines is fixed, resulting in too high frame height, inconvenient operation, high cost, and the strength of the frame cannot be guaranteed

[0008] 6. The guide sleeve is directly an opening, so that the same position of the capsule is repeatedly impacted by high-pressure gas, which seriously damages the service life of the capsule

[0009] 7. A large number of hydraulic valves will be used if hydraulic control check valves or accumulators are used for pressure maintenance, and as the hydraulic system prolongs, the wear of the check valves seriously affects the reliability of the hydraulic system, and the impact of the system also bigger

In the past, the bladder vulcanizing machine mostly used high-pressure air or superheated water, because it contained a lot of oxygen, and the oxidation of the bladder or water tire was very serious, which caused the glue to block the central mechanism and the valve of the thermal pipeline, which seriously affected the normal operation of the machine. use
