Engineering Contradiction Analysis
1Ease of operation
If a bar-shaped upper anvil is inserted into the compression chamber with one surface contact, then the workpiece can be forged, but misalignment occurs due to workpiece deformation and the workpiece strongly sticks to the anvils making removal difficult
Solution Approach 1:
The upper anvil is divided into multiple flat surfaces (first through fourth surfaces) arranged in a cross pattern, replacing the single bar-shaped anvil. This segmentation allows the load to be distributed across multiple contact points, preventing misalignment and reducing workpiece sticking while maintaining ease of removal.
Solution Approach 2:
The upper anvil uses asymmetric flat surfaces positioned at different locations rather than a symmetric bar shape. This asymmetric arrangement optimizes the distribution of contact points to prevent misalignment during forging while facilitating workpiece removal after processing.
2Device complexity
If the compression recess is provided at the one end edge portion with compression upper surface contact, then the structure is simple, but misalignment occurs due to upper jig portion inclination and the projecting corner portion gets damaged
Solution Approach 1:
The compression upper surface is segmented into multiple flat surfaces (first through fourth surfaces) arranged in a cross pattern. This segmentation distributes the compressive load across multiple points, preventing misalignment and protecting corner portions from damage while maintaining structural simplicity.
Solution Approach 2:
Different regions of the upper anvil have different functional qualities - the first through fourth flat surfaces provide load distribution and alignment stability, while the overall cross-shaped structure protects corner portions. This local quality differentiation solves both the simplicity and precision requirements.
