Plate Splitting Support Layout to Prevent Chips and Curved Cracks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trimming apparatuses produce chips during the cutting and elimination of scrap portions from aluminum alloy plates, leading to inefficiencies and poor surface quality.
Innovation Solution
A splitting apparatus and method that includes a lower mold, an upper blade, and a support member, where the upper blade is lowered to form a cut along a split target line while the support member prevents the scrap portion from collapsing, ensuring a linear crack and flattened cut end surface, thereby preventing chip production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the upper blade is lowered to cut the scrap portion in a floating state, then the scrap portion can be eliminated, but the scrap portion collapses causing curved cracks and chip production
Solution Approach 1:
The support member is positioned in advance under the scrap portion to prevent collapse during the cutting process. This preliminary support action ensures that the scrap portion remains stable when the upper blade cuts through, preventing curved cracks and chip production while maintaining efficient scrap elimination.
2Ease of operation
If the scrap portion is left in a floating state for easy removal, then the trimming process can be completed, but the free end side collapses downward forming projected portions
Solution Approach 1:
The support member is placed beforehand under the scrap portion to maintain its shape during cutting. This preliminary support prevents the free end from collapsing downward, ensuring the cut end surface remains flat while still allowing easy scrap removal after the cutting process.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents chip formation during plate material splitting, improving the quality of the cut surface and eliminating scrap portions efficiently.
Implementation Method 1
a cut is formed on the split target line of the plate material by the upper blade
Implementation Method 2
the second side with respect to the split target line of the plate material is supported by the support member

AI summary
A splitting apparatus includes: a lower mold configured to allow placement of a plate material on the lower mold and arranged on a first side with respect to a split target line of the plate material; an upper blade configured to be raised or lowered with respect to the lower mold; and a support member arranged on a second side with respect to the split target line of the plate material. The splitting apparatus is configured that, in a case where the upper blade is lowered with respect to the lower mold in a state where the plate material is supported by the lower mold and the support member, a cut is formed on the split target line of the plate material by the upper blade, a crack is formed in conjunction with formation of the cut, and the plate material is split along the split target line.
