Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cutting tools for elongated elements like threaded rods and sill bars often distort the shape or damage the thread, requiring reworking, which is time-consuming and inefficient, especially when dealing with soft materials or complex profiles.
Innovation Solution
A cutting tool with a matrix-shaped blade and support that provides form contact along a shearing plane, using removable dies with semi-cylindrical recesses complementary to the thread or profile, allowing precise cutting without distortion or damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional cutting tools (saw, disk, or shear) are used to cut solid elongated elements, then the cutting operation can be performed, but the curved shape is distorted or the thread is damaged, requiring reworking
Solution Approach 1:
The cutting tool is divided into two separate matrices (first matrix on support, second matrix on blade) that work together to perform the cutting operation. Each matrix has cutting edges shaped to match specific portions of the elongated element, allowing the cutting action to be segmented into coordinated movements that preserve the element's geometry while achieving efficient cutting.
Solution Approach 2:
The matrices act as intermediary elements between the cutting force and the elongated element. By providing form-contact through shaped cutting edges, the matrices mediate the cutting process in a way that distributes force appropriately and maintains the original shape and thread integrity, avoiding direct harmful contact that would cause distortion or damage.
2Ease of manufacture
If conventional cutting tools are used, then cutting can be performed, but reworking of the shape or thread is required, increasing time consumption
Solution Approach 1:
The matrices are pre-shaped with cutting edges that exactly match the form of the elongated element (e.g., threaded rod profiles). This preliminary preparation of the cutting edges ensures that when cutting occurs, the original shape and thread are preserved without requiring any subsequent reworking, thus eliminating time loss while maintaining cutting simplicity.
3Manufacturing precision
If the cutting tool is designed for specific thread types or profiles, then precise cutting can be achieved, but the tool's versatility is limited
Solution Approach 1:
The tool system is made dynamic by allowing the matrices to be interchangeable. Different matrices with different cutting edge shapes can be mounted on the support or blade depending on the type of elongated element to be cut. This dynamic reconfiguration capability allows the same basic tool structure to achieve precise cutting for various thread types and profiles, thereby maintaining both cutting precision and tool versatility.
Solution Approach 2:
The cutting tool is designed as a universal system where the same support and blade structure can accommodate multiple matrices designed for different element types. This multi-functionality allows a single tool to perform precise cutting on threaded rods, sill bars, or other elongated elements with different profiles, achieving both precision and versatility through the interchangeable matrix system.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables cutting of elongated elements without the need for reworking, maintaining the original shape and thread integrity, and extending the tool's applicability and lifespan through interchangeable dies.
Implementation Method 1
The cutting tool according to the invention is therefore a shearing effect tool along a shearing plane crossing a longitudinal axis of the elongated element, the shearing being carried out between a fixed blade mounted on the support, and a mobile blade mounted pivoting on the support

AI summary
The invention relates to a cutting tool for segmenting solid long elements following a shear plane, said tool comprising a base (1) and a blade (2) which is movably mounted on a holder (3) attached to the base (1), and enabling the blade (2) to be moved between an open position for receiving a solid long element (4) to be segmented between the blade (2) and the holder (3), and a closed position at the end of a cutting process. The blade (2) and the holder (3) are each provided with a die (5, 6) for receiving a solid long element (4) during the cutting process, the shape and size of the edge of each of the two dies (5, 6) complementing the shape and size of the solid long element (4) to be cut, measured adjacently to the shear plane.
