Punch and Die Setup Measurement for Faster Tool Equipping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing setup devices for tools used in punching or forming plate-shaped materials require lengthy processes to record and adjust for changes in tool dimensions due to wear, leading to increased setup time and potential inaccuracies in processing.
Innovation Solution
A setup device that allows for simultaneous measurement of punch length and die height using a measuring object with a defined thickness, enabling efficient recording of tool dimensions and alignment verification, thereby reducing setup time and ensuring accurate processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If separate measurement steps are used for punch length and die height, then measurement accuracy can be maintained, but setup time increases significantly
Solution Approach 1:
The patent combines the measurement of punch length and die height into a single integrated measurement step. The measuring device simultaneously captures both dimensions by positioning sensors to measure the punch length from the punch holder to the measuring surface, and the die height from the measuring object to the zero point of the die holder, eliminating the need for separate measurement operations and reducing setup time
2Productivity
If multiple measurement steps are performed sequentially, then comprehensive tool data can be collected, but productivity decreases
Solution Approach 1:
The patent implements continuous measurement action by having the measuring device capture both punch length and die height in an uninterrupted single operation. The measuring sensors continuously record dimensions as the punch holder is positioned, ensuring comprehensive data collection without interrupting the measurement flow, thereby maintaining precision while improving productivity
3Device complexity
If a simple measuring setup is used, then device complexity is reduced, but the ability to measure both punch length and die height simultaneously is lost
Solution Approach 1:
The patent designs the measuring device with universal functionality to perform multiple measurement tasks simultaneously. The same measuring device and sensor system can measure both punch length and die height in one operation, as well as verify punch-die alignment, making the device multi-functional without requiring complex additional components or multiple specialized measuring instruments
