Cutting Strand Segment With Depth Limiting Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting strand segments for machine tool parting devices face challenges in achieving precise cutting with minimal material removal and preventing chain tearing due to deep penetration into workpieces, while also requiring a compact and cost-effective design.
Innovation Solution
A cutting strand segment with a cutter support element, a cutting element, and a cutting depth limiting element that limits the maximum cutting depth to less than 0.5 mm, along with a transverse securing element to prevent lateral movement, is designed to form a compact and efficient cutting chain. The segment is lightweight, with a maximum weight of less than 1 g, and features a connecting element for secure assembly, allowing for precise cutting with reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cutting depth is increased to remove material faster, then productivity is improved, but the cutting strand segment experiences high loading that causes chain tearing
Solution Approach 1:
The cutting depth limiting element is pre-configured on the cutting carrier element to establish a maximum cutting depth before the cutting operation begins. This preliminary constraint prevents the cutting element from penetrating too deeply into the workpiece, thereby avoiding excessive loading that would cause chain tearing while still enabling efficient material removal within safe limits.
2Ease of manufacture
If the cutting strand segment design is simplified to reduce cost, then ease of manufacture is improved, but the precision of cutting depth control deteriorates
Solution Approach 1:
The cutting depth limiting element is designed with specific dimensional parameters (height, width, and profile) that directly determine the maximum cutting depth. By carefully selecting and configuring these geometric parameters during manufacturing, precise cutting depth control is achieved without requiring complex mechanisms or additional components, thus maintaining cost-effectiveness while ensuring precision.
3Ease of operation
If the cutting strand segment is made compact to reduce weight, then ease of operation is improved, but the structural complexity increases to maintain strength
Solution Approach 1:
The cutting depth limiting element is integrally formed with the cutting carrier element as a single unified component. This merging of functions allows the limiting element to be seamlessly integrated into the carrier structure without requiring separate parts or complex assembly mechanisms, thereby maintaining structural strength while keeping the overall design compact and easy to handle.

AI summary
The invention relates to a cutting strand segment for a cutting strand of a machine tool separating device, having at least one blade carrier element (16a; 16a'; 16b; 16b'; 16c), having at least one blade element (18a; 18a'; 18b; 18b'; 18c) arranged on the blade carrier element (16a; 16a'; 16b; 16b'; 16c) and having at least one cutting depth limiting element (20a; 20a'; 20b; 20b'; 20c) arranged on the blade carrier element (16a; 16a'; 16b; 16b'; 16c) for limiting a maximum cutting depth of the blade element (18a; 18a'; 18b; 18b'; 18c). According to the invention, the cutting depth limiting element (20a; 20a'; b; 20b'; 20c) limits a maximum cutting depth of the blade element (18a; 18a'; 18b; 8b'; 18c) to a value less than 0.5 mm.
