Description

Technical Field

[0001] The invention belongs to the technical field of tire vulcanization, and in particular relates to a tire unloading device for aviation bias tires. Background Art

[0002] Aircraft tires are important parts for aircraft takeoff, landing, and taxiing. They have distinctive characteristics such as high speed, high load, and impact resistance. Therefore, they need to have very superior performance and stable and reliable quality. The development level of aircraft tire manufacturing equipment is closely related to the stability of tire product quality.

[0003] The vulcanization process is the last process in the manufacture of aircraft tires. A well-controlled tire unloading method is a necessary guarantee for bias tires in the vulcanization process before entering the rear inflation device for inflation. When the traditional tire unloading method is used, since the cross-section of aviation bias tires is wider than that of civilian tires and the tire weight is heavier (the weight of 20" aviation bias tires is more than 60Kg), the tires have large inertia, large impact, and unstable sliding state when sliding on the tire unloading trolley and tire unloading roller. Since the connecting rod type B-type curing vulcanizer itself has a compact structure, the distance between the trolley and the upper steam chamber after the trolley is flipped into place is relatively close, resulting in frequent collisions between the bias aircraft tires and the steam chamber or other parts of the vulcanizer during sliding, resulting in tire scratches. The occurrence of scratches seriously affects the quality of aviation bias tires. Therefore, it is necessary to develop a new tire unloading device to solve the scratch problem that occurs when the tire slides from the tire unloading trolley to the rear inflation device of the vulcanizer.
