Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing numerical control machines for working sheet materials face challenges with complex and time-consuming tool replacement, limited versatility, and obstruction during operations due to the simultaneous mounting of rotary disks and waterjet cutting nozzles, requiring expert intervention and being costly to maintain.
Innovation Solution
A machine with interchangeable tools featuring male and female fast-coupling means allows for easy mounting and dismounting of rotary tools and waterjet cutting systems, enabling the use of either technology independently and simplifying tool replacement, with a hydraulic connection system that withstands high pressures without needing expert handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotary disk and waterjet cutting nozzle are simultaneously mounted on the supporting head, then the machine can perform both types of operations, but the replacement and mounting of tools becomes extremely complicated and requires expert intervention
Solution Approach 1:
The supporting head is divided into separate functional modules: a rotary disk assembly and a waterjet cutting assembly. Each module can be independently mounted, removed, or replaced without affecting the other, simplifying tool changes while maintaining versatility
Solution Approach 2:
The supporting head is designed with universal mounting interfaces that can accommodate both rotary disk tools and waterjet cutting nozzles. The quick-coupling mechanism provides a standardized connection system that simplifies the mounting and removal of different tool types
2Adaptability or versatility
If a rotary disk and waterjet cutting nozzle are simultaneously mounted on the supporting head, then the machine can perform both types of operations, but the presence of the non-working tool hinders the free independent movement of the working tool
Solution Approach 1:
The tool assembly is segmented into independently movable components. The rotary disk and waterjet nozzle are positioned on separate axes and can be independently adjusted, allowing the working tool to move freely without being constrained by the non-working tool
Solution Approach 2:
The supporting head incorporates dynamic positioning mechanisms that allow the working tool to be adjusted to various positions and angles. The non-working tool can be repositioned or removed to clear the path of the working tool, ensuring uninterrupted operation
3Ease of manufacture
If the waterjet cutting system is completely integral with the supporting head, then the mounting is simplified, but the machine becomes extremely expensive and requires dedicated equipment
Solution Approach 1:
The supporting head is designed with universal mounting interfaces that can accommodate both rotary disk tools and waterjet cutting nozzles. The quick-coupling mechanism provides a standardized connection system that simplifies the mounting and removal of different tool types, reducing the need for dedicated equipment
Solution Approach 2:
The waterjet cutting system is segmented into a modular assembly that can be independently mounted on the supporting head. This modular design maintains mounting simplicity while allowing the system to be configured for different operations, enhancing flexibility
4Reliability
If tool replacement is performed using traditional locking mechanisms, then the tools are firmly fixed, but the replacement operation is cumbersome, complicated and time-consuming
Solution Approach 1:
The quick-coupling mechanism incorporates pre-positioned locking and unlocking features that are prepared in advance. The coupling elements are designed with preliminary alignment guides and pre-loaded spring mechanisms that enable rapid tool changes without cumbersome manual operations
Solution Approach 2:
The quick-coupling mechanism incorporates self-locking features that automatically secure the tool in place upon insertion. The spring-loaded locking elements engage automatically, eliminating the need for manual tightening or complex locking procedures, thereby reducing tool replacement time while maintaining reliable fixation
