Composite Punch for Simultaneous Multi-Formula Powder Pressing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current punches for pressing powder cannot simultaneously compress multiple formulas in a pan without resulting in uneven hardness and performance issues, as they apply a single pressure, leading to over- or under-pressing depending on the caking agents present.
Innovation Solution
A punch with distinct regions made of different materials, allowing for varying pressures to be applied to different powder formulas within the same pan, ensuring each formula is pressed to the appropriate hardness for optimal payoff performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single solid metal punch is used to press multiple formulas, then the pressing process is simple, but the hardness uniformity deteriorates
Solution Approach 1:
The punch is divided into multiple regions with different material properties. Each region has a specific hardness tailored to the requirements of the corresponding powder formula, enabling localized pressure adjustment while maintaining a unified punch structure.
Solution Approach 2:
The punch combines multiple materials with different hardness levels in a single composite structure. This allows different regions of the punch to apply different pressures to different powder formulas simultaneously, achieving uniform hardness across multiple formulas while keeping the device relatively simple.
2Ease of operation
If a single pressure is applied to different formulas, then the pressing operation is straightforward, but the payoff performance deteriorates
Solution Approach 1:
Different regions of the punch are designed with specific material properties to apply localized pressures that optimize the payoff performance of each powder formula. This maintains ease of operation with a single pressing action while achieving reliable, optimized payoff for each formula.
3Manufacturing precision
If separate pressing of each formula is performed, then the hardness precision is improved, but the production time increases
Solution Approach 1:
Multiple pressing operations that were previously performed separately are merged into a single simultaneous pressing operation. The composite punch with different hardness regions allows multiple powder formulas to be pressed to their respective optimal hardesses in one action, doubling productivity while maintaining hardness precision.
Solution Approach 2:
The pressing process continues without interruption by performing multiple presses simultaneously in a single continuous action. This eliminates the time required for sequential operations while maintaining the precision of individual formula pressing through the specialized composite punch design.
4Device complexity
If formulas with different caking agents are pressed with the same pressure, then the pressing process is simple, but the hardness characteristics deteriorate
Solution Approach 1:
The punch is designed with regions of different material hardness corresponding to different powder formula locations. Each region applies the appropriate pressure for formulas with different caking agent contents, achieving precise hardness characteristics while keeping the pressing process simple and unified.

Function Achieved in This Case
Enables simultaneous pressing of multiple formulas in a single pan, achieving uniform hardness and performance across all formulas, reducing the time and cost associated with separate pressing and recombination methods.
Implementation Method 1
The first region is comprised of a first material and configured to apply a first predetermined pressure to a first powder formula when a ram force is placed on the punch body
Implementation Method 2
The second region is at least partially comprised of a second material and is configured to apply a second predetermined pressure to a second powder formula when the ram force is placed on the punch body

AI summary
A punch for simultaneously pressing two or more different powder formulas has a punch body with a first region and second region. The first region is comprised of a first material and configured to apply a first predetermined pressure to a first powder formula when a ram force is placed on the punch body. The second region is at least partially comprised of a second material and is configured to apply a second predetermined pressure to a second powder formula when the ram force is placed on the punch body. The second material is less hard than the first material such that the second predetermined pressure is less than the first predetermined pressure.
