Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abrasion test methods for molds used in metal forging require extensive preparation and cannot evaluate abrasion under high temperature and high pressure conditions, leading to inefficiencies and increased costs.
Innovation Solution
An abrasion test apparatus with a workpiece holding mechanism, a contact tool that rotates and intermittently heats, and a heating mechanism to simulate the abrasion of heated metal without requiring a mold that replicates the actual processing state, allowing for localized heating and reduced energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a mold simulating the actual processing state is prepared for abrasion testing, then the evaluation accuracy of mold abrasion is improved, but the preparation time and cost increase significantly
Solution Approach 1:
The patent uses a simplified contact tool that copies only the essential functional characteristics of the actual mold (surface geometry and material properties) rather than creating a complete replica. This allows abrasion testing to be performed with a simplified tool that captures the key wear mechanisms without requiring extensive mold preparation, thereby reducing time and cost while maintaining evaluation accuracy
Solution Approach 2:
The patent extracts the critical abrasion-inducing elements from the complete mold structure and concentrates them in a simplified contact tool. By taking out only the necessary components (contact surface and material composition) and eliminating unnecessary mold structures, the system achieves accurate abrasion evaluation without the time-consuming preparation of full-scale molds
2Temperature
If the entire test apparatus is heated to high temperature to simulate forging conditions, then the evaluation of abrasion under high temperature conditions is improved, but the energy consumption increases and stable operation becomes difficult
Solution Approach 1:
The patent applies heating only to the contact tool where the abrasion test occurs, rather than heating the entire test apparatus. This localized heating approach enables the simulation of high-temperature forging conditions at the test interface while minimizing energy consumption and avoiding the operational instability that would result from heating the entire system
Solution Approach 2:
The patent divides the test system into distinct thermal zones, with the contact tool being heated to high temperature while the rest of the apparatus remains at ambient or controlled temperature. This segmentation allows high-temperature abrasion evaluation without the prohibitive energy costs and stability issues of heating the entire apparatus
3Adaptability or versatility
If a mold with complex shape matching the workpiece is used for abrasion testing, then the realism of the test condition is improved, but the manufacturing cost and complexity increase
Solution Approach 1:
The patent creates a simplified contact tool that copies only the essential geometric features necessary for generating realistic abrasion conditions, rather than manufacturing a complete mold replica. This approach maintains test realism by preserving the critical contact geometry while dramatically reducing manufacturing complexity and cost
