Turret Punch Multi-Tool With Selectable Taps for Threading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Punching devices, particularly turret punching presses, are limited in their functionality as they primarily perform punching operations and lack the capability to efficiently cut or form threads, restricting their versatility.
Innovation Solution
A multiple tool system is designed for punching devices that includes a thread cutter drive mechanism, a link guide for selecting active thread cutters, and a lubrication system, allowing for the expansion of functionality to include thread cutting or forming, with features like a quickly removable tool head, automated selection, and a drive device that specifies the number of rotations via a selectable transmission ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a punching device is equipped with traditional single-function tools, then the device structure remains simple, but the functionality is limited and cannot perform thread cutting or forming operations
Solution Approach 1:
The punching device is equipped with a multi-tool that can perform multiple functions including punching, thread cutting, and thread forming operations. The multi-tool comprises multiple thread cutters with different thread diameters and types, allowing a single device to handle various fastening operations without requiring separate specialized tools for each function.
Solution Approach 2:
The multi-tool is divided into multiple independent thread cutter units, each capable of performing specific threading operations. This segmentation allows the device to handle different thread specifications (M6, M8, M10, etc.) and types (metric, unified, pipe threads) through individual selectable cutters, while maintaining a unified tool holder structure that integrates with the punching device.
2Adaptability or versatility
If multiple thread cutters are integrated into a single multi-tool, then thread cutting capability is enhanced, but the device complexity increases due to additional selection and drive mechanisms
Solution Approach 1:
Multiple thread cutters are combined into a single tool holder assembly, sharing common drive and selection mechanisms. The multi-tool integrates several thread cutter units (first, second, third thread cutters) with different thread specifications into one compact structure, reducing the need for multiple separate tools while minimizing additional complexity through shared components.
Solution Approach 2:
The multi-tool incorporates a rotatable tool holder that can dynamically switch between different thread cutter positions. The selection mechanism allows rotation to bring the desired thread cutter into the active working position, enabling flexible adaptation to different threading requirements without requiring complex individual control mechanisms for each cutter.
3Productivity
If automated selection mechanism is implemented, then operational efficiency is improved, but the device complexity and initial cost increase
Solution Approach 1:
The multi-tool incorporates an automated selection mechanism that can be actuated by the punching device's existing ram or actuator system. The tool holder rotates automatically to position the required thread cutter based on pre-programmed sequences or simple mechanical indexing, eliminating the need for manual intervention while utilizing the punching device's existing motion cycles for selection.
4Adaptability or versatility
If thread forming operation is added to punching device, then application possibilities are expanded, but the device complexity and operational time increase
Solution Approach 1:
The multi-tool is designed to perform thread forming operations continuously within the existing punching device cycle. The thread formers can engage and form threads during the same operational cycle as punching operations, eliminating separate threading steps and maintaining continuous productive action without significant additional time requirements.
