Tire Vulcanizer Shaping Unit Beadlock Mounting Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art tire vulcanization methods face inefficiencies due to long pre-vulcanization processing times and inaccuracies in mounting and shaping green tires, particularly lacking a beadlock mechanism which leads to positional and directional displacements.
Innovation Solution
A tire vulcanizer with a shaping unit featuring an inflatable tubular rubber bladder, clamp rings, and rotatable clamp members with beadlocks that securely engage and position the green tire's bead portions, ensuring accurate mounting and shaping, and a fluid supply system for tight contact with the bladder to facilitate vulcanization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the green tire is set in the center mechanism of the vulcanizer for shaping, then the green tire can be shaped, but pre-vulcanization processing takes a long time, causing a reduction in work efficiency
Solution Approach 1:
The system is divided into two independent parts: a shaping unit for green tire shaping and a vulcanizer body for vulcanization. The shaping unit can be detached and transferred to the vulcanizer body, allowing parallel preparation and eliminating waiting time, thus resolving the contradiction between shaping accuracy and work efficiency.
Solution Approach 2:
The green tire is shaped in advance in the shaping unit before being transferred to the vulcanizer body. This preliminary shaping action allows the vulcanization process to start immediately without waiting for shaping, improving work efficiency while maintaining shaping accuracy.
2Device complexity
If the shaping unit is structured the same as the center mechanism without a beadlock, then the structure is simpler, but the green tire is likely to be positionally or posturally displaced when mounted
Solution Approach 1:
The beadlock mechanism is extracted from the complex center mechanism and integrated into the simplified shaping unit. This selective extraction maintains only the essential beadlock function needed for mounting accuracy while keeping the overall structure simple.
Solution Approach 2:
The beadlock mechanism in the shaping unit automatically secures the green tire's bead portions during mounting, preventing positional and postural displacement without requiring additional complex positioning systems. The shaping unit itself provides the necessary securing function.
3Manufacturing precision
If the green tire is mounted and shaped accurately in the shaping unit, then high-performance tire molding is enabled, but the mounting and shaping processes become more complex
Solution Approach 1:
The mounting and shaping functions are merged into a single integrated shaping unit with beadlock mechanism. This combination achieves accurate tire molding through coordinated action of beadlocking and shaping in one device, rather than requiring separate complex systems for each function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables efficient and accurate mounting and shaping of green tires, preventing positional and directional displacements, allowing for immediate vulcanization and improved work efficiency while ensuring high-performance tire molding.
Implementation Method 1
a bladder of the center mechanism is inflated with a pressurized fluid to thereby make the outer circumference of a bladder in tight contact with the inner circumference of the green tire
Implementation Method 2
the right and left clamp members incorporate beadlocks which lock right and left bead portions of the green tire set in a periphery of the bladder of the shaping unit by directly engaging them with lock nails
Implementation Method 3
right and left clamp members being detachable from the clamp rings respectively and rotatable, in which the right and left clamp members incorporate beadlocks which lock right and left bead portions
Implementation Method 4
the green tire is held in a container of the vulcanizer, and then the inner circumference thereof is pressed into the bladder supplied with a high-temperature and pressure fluid, thereby vulcanizing the green tire by heat from the bladder and the container

AI summary
The invention provides a tire vulcanizer having a vulcanizer body and a shaping unit and configured to be able to accurately mount a green tire in the shaping unit and shape it accurately when shaping the green tire in the shaping unit. As a result, the green tire can be placed and set accurately in a lower container of the vulcanizer body when the shaping unit is placed in a container of the vulcanizer body. In order to mount the green tire in the shaping unit (B) outside the vulcanizer body, the tire vulcanizer includes outside the vulcanizer body (A) a tire mounting device (D) which mounts the green tire in the shaping unit.
