Stripping Tool Securing Element for Breakout Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stripping tools for removing punching waste from sheets are prone to damage during transport due to relative displacement of tool parts, causing breakout elements to protrude and potentially get damaged.
Innovation Solution
A securing element featuring a screw nut and threaded screw with a raised rear grip element prevents relative displacement of the tool parts, ensuring they remain at a defined distance and are precisely positioned, thereby preventing damage to the breakout elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foam components are used to maintain distance between tool parts during transport, then transport protection is improved, but under significant force the tool parts can still displace and compress the foam, causing breakout elements to protrude and potentially damage
Solution Approach 1:
The locking element is activated in advance during tool assembly or before transport, preventing relative displacement of tool parts before any harmful forces can occur. The threaded screw with rear gripping element is screwed into the screw nut to engage the breakout element, establishing protective engagement before transport conditions are encountered
Solution Approach 2:
The locking element applies a counteracting force in advance to prevent the harmful relative displacement between tool parts. The rear gripping element engages behind the breakout element to counteract any forces that might cause protrusion or damage during transport
2Stability of the object's composition
If the upper and lower tool parts are kept at a defined distance during transport using foam components, then transport stability is improved, but the breakout elements may still protrude through openings when force is applied, requiring additional protective measures
Solution Approach 1:
The locking element is engaged in advance to establish a mechanical constraint between tool parts that maintains the defined distance more reliably than foam alone. The threaded screw with rear gripping element creates a positive mechanical lock that prevents breakout element protrusion before transport forces are applied
3Reliability
If a locking element with threaded screw and screw nut is added to prevent relative displacement, then protection of breakout elements is improved, but device complexity increases
Solution Approach 1:
The locking element combines multiple functions into a single integrated assembly: the threaded screw provides both the locking mechanism and the rear gripping element for preventing displacement, while the screw nut provides both threading engagement and a bearing surface. This merging reduces the number of separate components compared to using multiple independent protective elements
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 relative movement between the tool parts, ensuring the breakout elements do not protrude, and allows for easy positioning of the stripping tool in a machine without the need for time-consuming readjustments, enhancing transport and operational safety.
Implementation Method 1
The locking element is formed by a screw nut formed or arranged in one tool part and further by a threaded screw
Implementation Method 2
at least one raised rear gripping element formed or arranged on the screw shaft of the threaded screw, which engages behind and/or under the associated tool part

AI summary
The stripping tool (1) has a safety element (8) which is provided for an accurate positioning of the tool portions (2,3) relative to one another, where the safety element is formed by a screw nut (9) and by a threaded screw (10). The screw nut is arranged in one of the tool portions. The threaded screw is guided by a screw recess (16) in the latter tool portion in a stripping tool-locking position with a screw shaft (11). The threaded screw is screwed with a thread (12) in the screw nut.
