Cutting Link Embossing for Stable Chainsaw Segment Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing cutting strand segments for machine tool parting devices are inefficient in achieving a mechanically stable connection between cutting elements and carrier elements, leading to increased assembly costs and potential interfering contours during production.
Innovation Solution
The method involves forming cutting elements and carrier elements in one piece using a single stamped blank, with the cutting element being embossed onto the carrier element, and incorporating a transverse securing element to prevent movement, thereby achieving a cost-effective and stable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cutting elements and carrier elements are produced separately and assembled, then assembly flexibility is maintained, but assembly effort and costs increase
Solution Approach 1:
The cutting element and carrier element are merged into a single integrated component produced from one stamped blank. The embossing process creates the cutting element protrusion directly on the carrier element, eliminating separate assembly steps and reducing overall complexity despite the advanced forming process used.
Solution Approach 2:
The single stamped blank serves multiple functions: it forms both the carrier element structure and the cutting element, creates embossed features for mechanical connection, and produces transverse securing elements. This multi-functionality reduces the number of separate components and assembly operations required.
2Strength
If cutting elements are formed by embossing onto carrier elements, then mechanical stability is improved, but production process complexity increases
Solution Approach 1:
The embossing process creates preliminary mechanical interlocking features during the forming stage itself. The cutting element protrusion is pre-formed on the carrier element before final assembly, ensuring mechanical stability is built into the structure during production rather than added through separate fastening operations.
Solution Approach 2:
The embossed cutting element and carrier element form a self-joining structure where the protrusion and recess automatically align and interlock during assembly. The transverse securing elements also self-form during embossing, creating a self-servicing connection that requires no additional fasteners or assembly operations.
3Ease of manufacture
If a single stamped blank is used to produce cutting and carrier elements, then assembly costs are reduced, but manufacturing precision requirements increase
Solution Approach 1:
The embossing process utilizes controlled plastic deformation parameters to form precise three-dimensional features from the stamped blank. By adjusting embossing depth, pressure, and tooling geometry, the cutting element protrusion and transverse securing elements achieve required precision without requiring additional machining or finishing operations.

AI summary
The invention relates to a method for producing a cutting unit segment of a cutting unit (12) of a machine tool separating device, comprising at least one cutter support element (16) and at least one cutter element (18). In at least one step, the cutter element (18) is molded on the cutter support element (16) by means of a drawing process in an at least partially staggered manner relative to an outer surface (20) of the cutter support element (16).
