Sealed Gas-Charging and Flanging for Shock Absorber Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gas-charging and flanging processes for shock absorbers are inefficient, as they require separate machines and can damage the sealing ring, affecting the sealing performance of the shock absorber assembly.
Innovation Solution
A gas-charging and flanging machine that integrates a sealed chamber for simultaneous gas charging and spinning/pressing flanging, using clamping mechanisms and a spin-and-press flanging device to enclose and form a sealed environment, ensuring the gas is charged and the workpiece is flanged without damaging the sealing ring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gas-charging and flanging are performed using different machines, then each machine can be optimized for its specific function, but production efficiency is reduced due to sequential processing
Solution Approach 1:
The patent combines the gas-charging device and spin-and-press flanging device into a single integrated machine. The gas-charging device includes clamping blocks and a gas intake nozzle, while the flanging device includes a spin-and-press mechanism with a sealing wheel. Both operations are performed within the same sealed chamber, eliminating the need for separate machines and sequential processing, thereby improving production efficiency.
2Productivity
If an insert is inserted through the sealing ring during gas-charging, then gas can be charged into the workpiece, but the sealing ring is damaged and sealing performance is affected
Solution Approach 1:
The patent introduces a sealed chamber as an intermediary environment that allows gas-charging to occur without directly penetrating the sealing ring. The gas-charging device charges gas into the workpiece through the sealed chamber, and the spin-and-press flanging device subsequently forms a flange that seals the chamber. This mediator approach enables gas-charging while preserving the sealing ring integrity.
3Loss of time
If gas-charging is performed before flanging, then production time is reduced, but the sealing ring may be damaged during the gas-charging process
Solution Approach 1:
The patent merges the gas-charging and flanging operations into a single integrated process within the same sealed chamber. The gas-charging device and spin-and-press flanging device work sequentially in the same environment, allowing gas-charging to occur before flanging without requiring separate machines or risking sealing ring damage through repeated handling.
4Device complexity
If separate machines are used for gas-charging and flanging, then each machine can be simpler in design, but the overall system requires more equipment and space
Solution Approach 1:
The patent creates a universal machine that performs both gas-charging and flanging functions. The sealed chamber serves as a multi-functional environment that accommodates both the gas-charging device and the spin-and-press flanging device. This multi-functionality approach consolidates what would traditionally require two separate machines into one integrated system, improving production efficiency while maintaining manageable complexity through shared infrastructure.
