Retractable Strip Guide Stamping Tool for Variable Blank Widths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The automobile industry faces increased manufacturing costs and production line downtime due to the need for multiple tool versions to accommodate various vehicle models and sheet metal dimensions, as well as labor-intensive tool changes during mass production.
Innovation Solution
A stamping tool with a lower part featuring retractable strip guides and fixed guides that allow for adjustable sheet metal advancement, enabling cutting of blanks with variable widths and thicknesses, and compatibility with different dies, eliminating the need for tool changes and reducing production downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tool versions are used to accommodate various vehicle models and sheet metal dimensions, then the adaptability to different production requirements is improved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The strip guides are made movable rather than fixed, allowing them to be repositioned along the advancement zone. This dynamic configuration enables a single tool to adapt to different sheet metal widths and vehicle model requirements without requiring multiple fixed tool versions, thereby reducing device complexity while maintaining versatility
Solution Approach 2:
The stamping tool is designed with universal strip guides that can serve multiple functions across different vehicle models and sheet dimensions. The retractable and repositionable strip guides allow the same tool to universally accommodate various blank types (roofs, doors, sides) without requiring model-specific tooling
2Adaptability or versatility
If tool changes are performed during mass production to accommodate different sheet metal models, then the adaptability to product variations is improved, but the productivity and manufacturing efficiency deteriorate due to labor and downtime
Solution Approach 1:
The strip guides can be dynamically repositioned during production without requiring complete tool changes. This allows quick adjustment between different blank types while maintaining production continuity, eliminating the productivity loss associated with full tool changes and repositioning
Solution Approach 2:
The strip guides are designed to be pre-positioned for different configurations, allowing operators to quickly switch between production modes without extensive setup time. The guides can be preliminarily arranged for specific vehicle models and then rapidly reconfigured when needed

AI summary
The invention relates to a press-forming tool for cutting blanks from a sheet metal strip (24) wound on a coil. The stamping tool comprises an upper part (22) and a lower part (2). The lower part (2) includes a sheet metal strip feed zone with an upper surface (6), and a blank-cutting blade for the sheet metal strip (24). The sheet metal strip feed zone (24) is laterally delimited by fixed strip guides (18). In addition, the lower part (2) includes retractable strip guides (20) under the upper surface (6). The retractable strip guides (20) are at least partially arranged within the strip feed zone so as to accommodate the width of the sheet metal (24) advancing in the stamping tool.
