Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller tools for machine tools are not adequately robust, flexible, or compact to efficiently handle metal sheets with varying thicknesses, especially those with small or large wall thicknesses, and require costly and space-intensive drive components.
Innovation Solution
A roller tool system with a form-fit profile rotary engagement for transmitting rotating movement, allowing for high torque transmission and precise control, and a compact configuration that eliminates the need for costly drive components, featuring a tool head with a reversible interaction with the ram and a roller installation with rotatably driven roller bodies for flexible operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional drive components are used to transmit rotating movement from the ram to the roller tool, then the roller tool can be operated on different machine tools, but the device becomes cost-intensive and intensive in terms of installation space
Solution Approach 1:
The tool head is designed with a universal form-fit profile rotary engagement that can transmit rotating movement from different types of rams (mechanical or hydraulic) across various machine tool brands, making the roller tool adaptable to multiple machine tools without requiring brand-specific or type-specific drive components
Solution Approach 2:
The patent extracts and eliminates the complex drive components (gears, belts, motors) from the roller tool design, retaining only the essential form-fit profile rotary engagement mechanism that directly transmits rotation from the ram to the roller body, thereby reducing device complexity and installation space
2Adaptability or versatility
If the roller tool is configured with pivotable drive components for variable machining directions, then the roller tool can operate in variable machining directions, but the device complexity and installation space increase
Solution Approach 1:
The form-fit profile rotary engagement is designed to be direction-agnostic, capable of transmitting rotating movement effectively regardless of the machining direction, eliminating the need for pivotable or adjustable drive components while maintaining versatility in variable machining directions
3Reliability
If a robust tool head is dimensioned for transmitting contact pressure force and rotating movement, then high torques can be transmitted reliably, but the roller tool configuration becomes less compact
Solution Approach 1:
The patent merges the functions of contact pressure force transmission and rotating movement transmission into a single integrated tool head structure with a form-fit profile rotary engagement, eliminating the need for separate robust drive mechanisms and achieving compact configuration while maintaining reliable high torque transmission
4Productivity
If multiple machining tools are disposed in the same space, then the machining output of the machine tool can be increased, but the space requirements for each tool must be reduced
Solution Approach 1:
By extracting and eliminating unnecessary drive components and mechanical interfaces from the roller tool design, the patent reduces the volume occupied by each tool, enabling more machining tools to be disposed in the same space and thereby increasing the machining output of the machine tool
