Solution Overview
Problem
The rotational bearing in existing compressive torsion forming devices cannot structurally withstand high applied pressures, limiting the increase in pressure that can be applied to processing materials.
Innovation Solution
A compressive torsion forming device with a sliding portion and a rotating table supported by a rotational bearing, where a second hydraulic chamber communicates with the first hydraulic chamber to distribute the thrust load, reducing the load on the rotational bearing and allowing for higher applied pressures, and incorporating a rotating mechanism with a turning bearing to manage anti-thrust loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotational bearing is used to support the rotating die, then the die can be rotated during compression, but the bearing cannot structurally withstand large applied pressures
Solution Approach 1:
The patent replaces the traditional mechanical bearing support system with a hydraulic support system. A hydraulic chamber is introduced between the rotating table and the table support portion, where hydraulic pressure acts to support the thrust load. This substitution allows the system to withstand large applied pressures that would be impossible for a mechanical bearing to handle, while still enabling rotation through the hydraulic pressure distribution.
Solution Approach 2:
The patent directly applies hydraulic principles by introducing a hydraulic chamber that uses fluid pressure to support the rotating table against large compressive loads. The hydraulic fluid distributes the thrust load across a larger area, enabling the system to handle pressures far beyond the capacity of conventional mechanical bearings while maintaining rotational capability.
2Productivity
If the applied pressure to the processing material is increased, then the material processing effectiveness is improved, but the thrust load on the rotational bearing increases beyond its structural capacity
Solution Approach 1:
The patent substitutes the mechanical bearing's load-bearing function with a hydraulic support system. The hydraulic chamber distributes the thrust load generated by high applied pressures across the rotating table, allowing the system to achieve high material processing effectiveness without overloading any single mechanical component.
Solution Approach 2:
The patent changes the fundamental parameter of load support from solid-to-solid mechanical contact (bearing) to fluid pressure distribution (hydraulic). This parameter change allows the system to handle variable high loads dynamically, adjusting the hydraulic pressure to match the applied compression force while preventing excessive thrust load on any single point.
3Device complexity
If a traditional bearing structure is used, then the device structure is simple, but the maximum applied pressure is limited by the bearing's structural capacity
Solution Approach 1:
The patent introduces a hydraulic chamber and fluid pressure system to replace the simple mechanical bearing structure. While this increases device complexity, it enables the system to withstand and apply much higher pressures to the processing material, overcoming the fundamental limitation of mechanical bearing capacity.
Solution Approach 2:
The patent replaces the simple mechanical bearing system with a hydraulic support mechanism. This substitution increases structural complexity but removes the upper pressure limit imposed by bearing material strength, allowing the system to achieve much higher applied pressures for improved material processing.
