Diamond Segment Weld Pad Structure for Stronger Cutting Chains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy chains with conventional diamond segments face limitations in achieving both adequate strength and cutting performance, constraining the development of diamond layer formulations for faster cuts with less damage.
Innovation Solution
The introduction of a chain link with a sintered diamond layer coupled to a weld pad, where the weld pad extends the full length and width of the diamond layer, providing enhanced mechanical strength and stability, and the diamond layer is sintered with a matrix material like cobalt, nickel, or iron, allowing for improved cutting efficiency and reduced wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional diamond segment is used, then the cutting element can perform cutting operations, but the diamond layer lacks adequate mechanical strength and is prone to damage
Solution Approach 1:
The cutting element is divided into two distinct segments: a diamond layer for cutting performance and a separate weld pad substrate for mechanical strength. This segmentation allows each component to be optimized independently - the diamond layer can be formulated for cutting efficiency while the weld pad provides the necessary structural support and damage resistance.
Solution Approach 2:
The invention uses a composite structure combining diamond material with a metal matrix (such as nickel, cobalt, or iron) in the weld pad. This composite approach allows the diamond layer to provide superior cutting performance while the metal matrix provides mechanical strength, toughness, and damage resistance, resolving the contradiction between strength and complexity.
2Reliability
If the diamond layer is made stronger to withstand sudden stops, then damage resistance improves, but cutting performance may be compromised
Solution Approach 1:
By separating the diamond layer from the structural support function (placed in the weld pad), the system allows the diamond layer to be optimized purely for cutting performance and speed, while the weld pad independently provides the strength and toughness needed for damage resistance during sudden stops.
Solution Approach 2:
The weld pad acts as an intermediary between the diamond layer and the drive link, absorbing impact forces and protecting the diamond layer from damage during sudden stops, thereby maintaining both high cutting speed and damage resistance.
3Strength
If a weld pad is added to the diamond segment, then mechanical strength and stability improve, but the device complexity increases
Solution Approach 1:
The weld pad is merged with the diamond layer to form an integrated diamond segment assembly where the two components are permanently joined. This merging creates a unified structure that provides both the cutting performance of diamond and the mechanical strength of the metal weld pad, while the entire assembly is designed to fit within existing chain link configurations to minimize overall complexity.

AI summary
A diamond segment may include a steel weld pad that is configured to be coupled with a drive link of a cutting chain. The diamond segment may further include a diamond layer that is coupled with the steel weld pad such that the diamond layer extends along a height of the steel weld pad at a peripheral portion of the steel weld pad. Other embodiments may be described and claimed.
