Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sheet processing machines require a mechanism for fast and reliable alignment and exchange of blanking tools to minimize downtime, as existing methods are inefficient in securing the tools during operations.
Innovation Solution
A tool clamping assembly with a frame and aligning mechanism that includes a clamping element, which can be displaced between open and clamping positions, applying force components along two perpendicular directions to secure the blanking tool, utilizing a combination of alignment and clamping mechanisms for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional clamping mechanism is used to secure the blanking tool, then the tool position is stable during operation, but the exchange time is long and downtime increases
Solution Approach 1:
The clamping mechanism is divided into multiple independent clamping elements (at least two) that can act simultaneously on different sides of the blanking tool. This segmentation allows for parallel clamping action, reducing the time required to secure the tool while maintaining stability through distributed force application.
Solution Approach 2:
The aligning mechanism performs preliminary alignment of the blanking tool in a first direction before the clamping elements are fully engaged. This preliminary action ensures that when clamping occurs, the tool is already positioned correctly, reducing adjustment time and ensuring stability without requiring complex post-clamping adjustments.
2Reliability
If multiple clamping elements are used to secure the tool in multiple directions, then the tool position stability is improved, but the device complexity increases
Solution Approach 1:
The clamping elements are designed with multi-functionality, serving both as positioning elements and as clamping force application points. Each clamping element can apply force in multiple directions (second and third directions perpendicular to each other), eliminating the need for separate positioning and clamping mechanisms, thus reducing overall device complexity while maintaining stability.
Solution Approach 2:
The aligning mechanism and clamping elements are integrated into a unified tool clamping assembly where the frame houses both components. The aligning mechanism and clamping elements work together as a coordinated system rather than separate mechanisms, reducing the number of independent components and simplifying the overall structure while ensuring both alignment and secure positioning.
3Reliability
If the clamping element applies strong clamping force to secure the tool, then the tool stability is improved, but the difficulty of quick release increases
Solution Approach 1:
The clamping elements are designed to be dynamically controllable, allowing for rapid transition between clamped and released states. The mechanism enables the clamping force to be applied strongly when needed for stability, but can be quickly released when tool exchange is required, achieving both secure clamping and easy operation through dynamic control capability.

AI summary
A tool clamping assembly (38) for clamping a blanking tool (40) intended to be used in a blanking station of a sheet processing machine has a frame (46) to which the blanking tool (40) is to be clamped and at least one clamping element (48). The frame (46) has an aligning mechanism adapted for aligning the blanking tool (40) in a first direction. Further, the frame (40) has at least one support surface (60) oriented to support the blanking tool (40) in a second direction which is perpendicular to the first direction, and at least one abutment surface (62) oriented to support the blanking tool (40) in a third direction which is perpendicular to the first and second directions. The clamping element (48) is displaceable between an open position and a clamping position, the clamping element (48) being adapted for clamping the blanking tool (40) against both the support surface (60) and the abutment surface (62).Further, a blanking tool assembly with such a tool clamping assembly is shown.
