Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bending tools face challenges in achieving secure and simple attachment in multiple operating positions, leading to imperfect mounting and hindered tool change processes in bending machines.
Innovation Solution
A bending tool design featuring a plate-shaped base body with angled head parts and working sections, allowing for unhindered formation of work sections and secure attachment, along with a compact and efficient design that enables central force introduction and reduced space requirements, facilitating easy tool change and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bending tool is designed with head parts and working sections arranged opposite each other on end faces, then the tool can be used in multiple positions, but the tool may tip over and cannot be securely mounted in all operating positions
Solution Approach 1:
The bending tool is divided into distinct functional segments: head parts (35, 36) for mounting and working sections (37, 38) for operation. These segments are spatially separated and arranged on different end faces of the base body (28), allowing independent optimization of each function while maintaining structural integrity for secure mounting in multiple positions.
2Ease of manufacture
If head parts are arranged directly one after the other forming a corner region, then unhindered formation of work sections is enabled, but the tool change process becomes more complex
Solution Approach 1:
The head parts (35, 36) are arranged in a corner region of the base body (28) at angles to each other when viewed in the circumferential direction of the end faces. This three-dimensional angular arrangement allows working sections to form without interference while maintaining a compact structure that simplifies tool change through simple pivoting movements in the YZ plane.
3Reliability
If additional projecting shoulders or approaches are added to the bending tool, then mounting support is provided, but sufficient free space around the tool is reduced
Solution Approach 1:
The end faces of the base body (28) serve multiple functions: they provide full-area support surfaces for mounting in the tool holder, define the angular arrangement of head parts (35, 36), and maintain a compact profile that preserves free space. The corner region arrangement of head parts allows the end faces to act as both support surfaces and structural elements without requiring additional projecting features.

AI summary
The invention relates to a bending tool (4), in particular a head-supported design, comprising a plate-shaped base body (28) with a first flat side (29) and a second flat side (30), as well as circumferentially arranged end faces (31, 32, 33, 34). The base body (28) has a first head section (35) and a first working section (37), as well as a second head section (36) and a second working section (38). The first head section (35) and the second head section (36) are arranged directly one after the other in the circumferential direction of the end faces (31, 32, 33, 34) of the base body (28), wherein the first head section (35) and the first working section (37), as well as the second head section (36) and the second working section (38), are each arranged opposite each other on the end faces (31, 32, 33, 34). The invention also relates to a manufacturing plant (1) with a bending press (3) and a bending tool (4) designed in this way.
