Solution Overview
Problem
Existing ceramic and metal powder presses are cumbersome and costly due to their rigid structure, requiring large components and high material consumption to accommodate variously shaped pressed parts, leading to increased weight, space requirements, and material costs, with complex adjustment drives and high material thickness contributing to instability and inefficiency.
Innovation Solution
A modular ceramic and metal powder press tool with adjustable stamp carriers and electric motor-driven adjustment drives, featuring coupling rods and spindle nuts for precise control, allowing for compact design and reduced overall height, with height-adjustable fixed stops and flexible component dimensions to accommodate diverse pressing forces and part shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rigid structure with large components is used to accommodate variously shaped pressed parts, then adaptability is improved, but weight increases
Solution Approach 1:
The press tool is divided into modular components including interchangeable stamp carriers, adjustable fixed stops, and separable die sets. Each module can be independently selected and configured based on the specific pressed part requirements, allowing adaptability without requiring the entire tool to be oversized and heavy.
Solution Approach 2:
The press tool incorporates adjustable elements such as height-adjustable fixed stops and positionable stamp carriers that can be dynamically reconfigured for different pressed part geometries. This dynamic adjustability replaces the need for multiple heavy rigid tooling sets, reducing overall weight while maintaining versatility.
2Strength
If large components with high material thickness are used to transmit pressing force, then strength is improved, but device complexity increases
Solution Approach 1:
Material thickness and component dimensions are optimized locally based on the actual pressing force requirements for each specific position and application. Rather than uniformly thick components throughout, the structure uses variable thickness where needed, reducing overall complexity while maintaining sufficient strength at critical locations.
Solution Approach 2:
The pressing force transmission capability is adjusted by changing parameters such as component geometry, material selection, and structural configuration rather than simply increasing material thickness uniformly. This allows strength to be optimized for each specific application without unnecessarily increasing device complexity.
3Adaptability or versatility
If height-adjustable fixed stops are used to accommodate different pressed parts, then adaptability is improved, but manufacturing precision deteriorates
Solution Approach 1:
The fixed stops and stamp carriers are pre-adjusted to precise positions before the pressing operation begins. This preliminary positioning ensures that when the pressing force is applied, all components are already correctly aligned, maintaining manufacturing precision despite the adjustability feature.
Solution Approach 2:
Mechanical adjustment mechanisms for the fixed stops are replaced or supplemented with precision positioning systems that use controlled movement and locking mechanisms to achieve and maintain precise positions. This substitution ensures that adjustability does not compromise the precision required for high-quality pressed parts.
