Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sheet processing machines require multiple specialized frames for different processing techniques, leading to increased complexity, space requirements, high production costs, and prolonged off-time due to frame changes, posing safety hazards.
Innovation Solution
A hybrid blanking frame that integrates a circumferential frame with a movable bar, supporting full-sheet-delivery, guillotine, and quick-lock blanking setups, allowing a single frame to adapt to various operations with interchangeable components and adjustable dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple specialized frames are used for different processing techniques, then each frame can be optimized for its specific function, but the device complexity increases and more storage space is required
Solution Approach 1:
The patent implements a universal frame structure that can perform multiple blanking operations (guillotine blanking, quick-lock blanking, and full-sheet delivery) through interchangeable components and adjustable mechanisms. The circumferential frame with movable bar and various mounting mechanisms allows a single frame to replace multiple specialized frames, directly resolving the contradiction between versatility and complexity.
2Adaptability or versatility
If multiple specialized frames are used for different processing techniques, then each frame can be optimized for its specific function, but production expenses increase due to manufacturing and maintaining multiple frames
Solution Approach 1:
The universal frame design reduces production expenses by manufacturing a single frame structure instead of multiple specialized frames. The frame body is produced once, and only the interchangeable components (mounting mechanisms, guide pins, template bars) need to be manufactured in variants, significantly reducing overall manufacturing costs while maintaining adaptability across different processing techniques.
3Adaptability or versatility
If multiple specialized frames are used for different processing techniques, then each frame can be optimized for its specific function, but the off time increases due to frame interchange operations
Solution Approach 1:
The frame incorporates dynamic and adjustable components such as the movable bar that can be repositioned along the circumferential frame, and quick-change mounting mechanisms that allow rapid interchange of blanking setups. These dynamic features enable fast adaptation between different processing techniques without requiring complete frame replacement, significantly reducing off time while maintaining versatility.
4Adaptability or versatility
If multiple specialized frames are used for different processing techniques, then each frame can be optimized for its specific function, but safety hazards increase due to carrying frames in and out of the machine platform
Solution Approach 1:
By implementing a universal frame that remains installed on the machine platform and can be reconfigured for different operations, the patent eliminates the need to physically carry frames in and out of the machine. The frame stays in place while components are interchanged, removing the safety hazards associated with manual frame handling while preserving adaptability through component interchangeability.
