Interchangeable Tool Punch and Die Holder Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal sheet processing machines face limitations due to spatial restrictions at tool holders, which restrict the use of tools with varying heights and complicate tool changes, limiting flexibility and tool stability.
Innovation Solution
The machine features positionable tool punch and die holders driven by separate drives, allowing for tools with differing heights to be securely mounted and adjusted along a stroke axis, enabling flexible tool configuration and increased installation space for improved stability and tool element usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tools with varying heights are used to expand processing flexibility, then adaptability is improved, but spatial restrictions at tool holders cause instability and processing issues
Solution Approach 1:
The patent implements separate, independent positioning drives for the tool punch holder and tool die holder along the stroke axis. These drives enable dynamic adjustment of each holder's position based on the specific height of the mounted tools, allowing the system to adapt to varying tool configurations while maintaining stable processing conditions through active position control.
Solution Approach 2:
The system changes the positional parameters of the tool holders along the stroke axis according to the height parameters of the mounted tools. By adjusting the starting positions and movement ranges of the punch holder and die holder independently, the system accommodates tools of different heights while ensuring reliable processing throughout the stroke.
2Device complexity
If tool holder spatial space is reduced for compact machine design, then device complexity is reduced, but tool stability and installation space are worsened
Solution Approach 1:
The patent divides the positioning system into two independent segments: a tool punch holder with its own positioning drive and a tool die holder with its own positioning drive. This segmentation allows each holder to be optimized independently for stability while maintaining overall machine compactness through coordinated control of the two segments.
Solution Approach 2:
The patent utilizes the stroke axis dimension to provide adjustment range for the tool holders. By positioning the holders at different locations along the stroke axis and allowing independent movement in this dimension, the system creates sufficient installation space and stability without increasing the machine's footprint in other dimensions.
3Adaptability or versatility
If separate positioning drives are implemented for tool punch and die holders, then adaptability to varying tool heights is improved, but device complexity increases
Solution Approach 1:
The separate positioning drives for the tool punch holder and tool die holder serve multiple functions: they enable adaptation to varying tool heights, maintain processing stability, control the stroke motion, and facilitate tool changing operations. This multi-functionality justifies the additional drive components by consolidating multiple requirements into a unified control system.

AI summary
A plate workpiece processing machine includes a workpiece support, a tool punch holder, a tool die holder, a tool drive, multiple tool punches, and multiple tool dies. Various tool punches and tool dies have tool heads of differing heights. The tool punch holder is positionable based on the tool head height of a tool punch secured to the tool punch holder and/or the tool die holder is positionable based on the tool head height of a tool die secured to the tool die holder.
