Cutting Die Resistance Member for Scrap Discharge Clog Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During cutting operations, swarf generated by cutting chips often clogs the scrap discharge hole, leading to scratches on the workpiece's back surface and disrupting machining processes.
Innovation Solution
Incorporating a resistance member that guides and collides with the swarf, finely dividing it and preventing it from reentering the scrap discharge hole, thereby maintaining the workpiece's value and ensuring continuous machining without clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cutting chip is used for cutting works, then cutting operations can be performed, but swarf clogs the scrap discharge hole causing scratches on the workpiece back surface
Solution Approach 1:
The invention introduces a resistance member with multiple through-holes that segments the swarf into smaller particles. The swarf passes through multiple small openings in the resistance member, which divides it into fine particles that can be properly discharged through the scrap discharge hole, preventing clogging and subsequent scratching of the workpiece back surface.
Solution Approach 2:
The resistance member acts as an intermediary between the cutting chip and the scrap discharge hole. It receives the swarf from the cutting chip, processes it by dividing it through its through-holes, and then allows the divided swarf to pass into the scrap discharge hole, thereby solving the clogging problem.
2Device complexity
If swarf is not divided, then the discharge hole structure remains simple, but swarf remains in the scrap discharge hole causing clogging
Solution Approach 1:
The resistance member is integrated into the discharge hole structure with multiple through-holes, creating a segmented path for swarf discharge. This segmentation divides the swarf into smaller particles during passage, enabling reliable discharge without requiring a completely separate complex disposal system.
Solution Approach 2:
The resistance member is merged with the die structure, combining the swarf division function with the existing discharge hole structure. This integration adds the division capability while maintaining a relatively simple overall structure, avoiding the need for separate complex swarf management systems.

AI summary
In a cutting die D having a cutting chip 50, applied to a punch press, and cutting a work W in collaboration with a cutting punch P, a resistance member 51 (53, 55, 56) for guiding swarf K generated during cutting of the work W through the cutting chip 50 and dividing it by giving resistance to it is provided around a scrap discharge hole 39 so that the divided swarf K does not remain in the scrap discharge hole 39 but is discharged to an outside so as to prevent clogging by scrap.
