Integrated Stripping Device for Insulated Flat Material Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing busbars with bends are inefficient, as the stripping process is typically done separately from the bending process, leading to increased productivity loss and potential damage to the carrier material.
Innovation Solution
Integrating a stripping device into the bending machine allows for a continuous stripping process before the bending part is separated, eliminating the need for separate handling and reducing non-productive time, with precise control over the stripping operation to ensure a clean and undamaged surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stripping is performed separately from bending using stand-alone stripping machines, then the stripping operation can be performed on finished bent parts, but this leads to increased productivity loss and additional handling requirements
Solution Approach 1:
The patent combines the stripping device with the bending machine into an integrated system. The stripping unit is positioned within the bending machine frame and processes the flat material during the bending operation, eliminating the need for separate stand-alone stripping machines and reducing material handling steps between operations.
Solution Approach 2:
The stripping operation is performed on the flat material before the bending part is separated from the supplied material. This preliminary stripping action allows the material to be prepared while still guided in the bending machine, avoiding subsequent handling of finished bent parts.
2Adaptability or versatility
If separate stand-alone stripping machines are used, then the stripping operation can be performed independently, but this requires additional handling equipment and increases non-productive time
Solution Approach 1:
The stripping device is integrated into the bending machine structure, sharing the same frame and control system. This merger reduces the number of separate devices needed while maintaining process flexibility through coordinated control of both bending and stripping operations.
Solution Approach 2:
The bending machine is designed to perform multiple functions: bending the flat material and stripping the insulation layer. The integrated system uses a single machine platform to execute both operations, reducing equipment complexity while maintaining adaptability.
3Reliability
If flat material is transported to separate stripping devices, then the stripping operation can be performed on finished parts, but this increases the risk of damage to the carrier material
Solution Approach 1:
The stripping operation is performed while the flat material is still guided in the bending machine, before the bending part is separated. This preliminary action eliminates the need to transport finished bent parts to separate stripping devices, reducing handling steps and damage risk.
Solution Approach 2:
The flat material itself serves as the intermediary that connects the bending and stripping operations. By processing the material while it is being fed through the bending machine, the system eliminates the need for separate transport and handling intermediaries that could cause damage.

AI summary
In a method for producing a bent part from insulated flat material (190) which has a flat electrically conductive support material which is surrounded by an electrically insulating insulation layer, the insulated flat material is supplied from a material store to a bending machine (100) and formed in the bending machine into a two- or three-dimensionally bent part consisting of insulated flat material. The bent part is then separated from the supplied insulated flat material in a cutting operation. In at least one section of the insulated flat material, some of the insulation layer is removed from the electrically conductive support material in an insulation-stripping operation. In the method, the insulation-stripping operation is carried out in a continuous process on the flat material guided in the bending machine, by means of an insulation-stripping device (200) integrated in the bending machine (100), before the bent part is separataed from the supplied flat material. The invention also relates to a system for producing bent parts from insulated flat material.
