Press Tool Plane Plate with Nested Guide Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing press tools for producing green compacts have issues with varying elasticities between tool levels, leading to problematic demolding and potential cracks in the green body due to different expansion of components, and they have a large overall height and weight, making them cumbersome and costly.
Innovation Solution
A level plate design with a one-piece construction, featuring cylindrical guide surfaces at different heights to reduce torque and tilting, and a centrally arranged receptacle to minimize torque, allowing for a nested arrangement of plates to reduce overall height and weight, and using additive processes to adjust rigidity and weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual plane plates are spaced apart and permanently arranged at different heights, then the press tool can accommodate multiple tool levels, but the overall height and weight increase, making the structure cumbersome
Solution Approach 1:
The patent applies nesting by arranging plane plates at the same height level, allowing them to be stacked vertically like nested dolls. This enables multiple tool levels to be accommodated within a compact height, as each plane plate can support tool components while maintaining alignment with guide columns.
Solution Approach 2:
The patent transitions from vertical stacking (different heights) to horizontal arrangement (same height level), utilizing the radial dimension to accommodate multiple tool levels. This dimensional change allows plane plates to be arranged side-by-side rather than one above the other, reducing overall height.
2Adaptability or versatility
If individual plane plates are spaced apart and permanently arranged at different heights, then the press tool can accommodate multiple tool levels, but the weight increases, making the structure costly
Solution Approach 1:
By nesting tool levels at the same height level on a single plane plate, the patent eliminates the need for multiple separate plane plates at different heights. This reduces the total weight of stationary components while maintaining the capability to accommodate multiple tool levels through vertical stacking of tool components.
3Device complexity
If guide surfaces are arranged at the same height, then the plane plate structure is simplified, but torque and tilting increase during operation
Solution Approach 1:
The patent introduces asymmetry by positioning guide surfaces at different height levels on the plane plate. This asymmetric arrangement creates a stabilizing effect where the vertical offset of guide surfaces counteracts torque and tilting forces during operation, while the guide surfaces remain coaxially aligned.
4Adaptability or versatility
If different elasticities exist between tool levels, then the press tool can accommodate varying tool configurations, but demolding becomes problematic and cracks may form
Solution Approach 1:
The patent creates equipotentiality in elasticity by arranging all tool levels at the same height level on a single plane plate. This ensures that all tool levels experience identical elastic deformation characteristics during pressing and demolding, preventing differential expansion that could cause cracks or demolding issues.
