Rotating Stripping Head with Parallel Drive Shafts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation stripping apparatuses for conductors, particularly those with multilayer insulation, face complexity in actuating blades and centering jaws due to the use of pivotable levers and cages, leading to increased manufacturing costs and reduced precision.
Innovation Solution
The use of drive shafts parallel or at an acute angle to the main axis for actuating insulation stripping blades and centering jaws, allowing for electromechanical or motor-driven rotation, simplifies the apparatus design and reduces production costs while maintaining precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If pivotable levers and cages are used to actuate blades and centering jaws, then the apparatus can function, but the device complexity increases and manufacturing precision decreases
Solution Approach 1:
The patent removes the complex pivotable lever mechanism and cage from the actuation system. Instead, it uses a simplified drive shaft with radially displaceable insulation stripping blades and centering jaws that are directly actuated by the drive shaft's movement, eliminating the intermediary levers and cages that caused complexity and precision issues.
Solution Approach 2:
The drive shaft serves multiple functions simultaneously: it rotates to advance the cable, it radially displaces to actuate both the insulation stripping blades and centering jaws, and it provides the structural framework for the entire stripping head. This multi-functionality eliminates the need for separate actuation mechanisms for different components.
2Ease of manufacture
If pivotable levers are used for actuation, then the apparatus can operate, but the ease of manufacture decreases due to complicated mounting and transmission
Solution Approach 1:
The patent eliminates the pivotable lever mechanism entirely, removing the complicated mounting and transmission components associated with levers. The direct radial displacement mechanism simplifies both manufacturing and adjustment operations.
Solution Approach 2:
The patent introduces a cam mechanism as an intermediary between the drive shaft and the radially displaceable blades/jaws. This cam mechanism simplifies the transmission of motion by converting the drive shaft's rotation into controlled radial displacement, making both manufacturing and operation easier compared to direct lever connections.
3Device complexity
If cages are used to rotate with the blades, then the blades can be fed in, but the device complexity increases with grooved tracks and peg mechanisms
Solution Approach 1:
The patent removes the cage, grooved tracks, and peg mechanisms from the blade actuation system. The radially displaceable blades are directly actuated by the drive shaft's radial movement, eliminating the complex cage-based mechanism while maintaining effective blade feeding.
Solution Approach 2:
The drive shaft itself performs the actuation function that previously required a separate cage mechanism. By integrating the actuation function into the drive shaft's radial displacement capability, the system achieves blade feeding efficiency without the complexity of additional rotating components.

AI summary
The invention relates to a novel insulation stripping head which can also be used in particular as a spare part for existing rotational insulation stripping apparatuses. It is particularly stable and simple to produce while at the same time providing the same or improved precision. It substantially has insulation stripping blades (3) and centering jaws (4) which can be swiveled in laterally and, during operation for insulation stripping, rotate together about the main axis (1).
