Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for cutting through holes in fibrous or cellular insulating materials, such as glass wool, often damage the material or fail to precisely control hole dimensions, especially when dealing with thick sections.
Innovation Solution
A method and device involving a cutting tool with a profiled shape and vibratory movement, guided along a traversing direction to minimize material damage, using a support with a passage hole and optionally aided by gas expulsion to remove the insulating material, allowing for precise control of hole dimensions and shapes like square, T-shaped, or circular sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional cutting blades are used to cut through holes in thick insulating material, then cutting capability is achieved, but material damage and crushing occur around the hole
Solution Approach 1:
The cutting tool is equipped with a vibratory mechanism that generates high-frequency oscillations during the cutting process. This vibration reduces friction between the cutting edge and the insulating material, allows the tool to penetrate more easily through thick material, and minimizes crushing and damage to the material structure around the hole.
Solution Approach 2:
The cutting process utilizes changes in physical parameters including vibratory frequency, cutting speed, and tool geometry. By optimizing these parameters, the tool can effectively cut through thick insulating material while controlling the degree of material deformation and damage in the surrounding area.
2Productivity
If conventional cutting methods are used, then cutting action is achieved, but precise control of hole dimensions is not possible
Solution Approach 1:
Before the final cutting action, the cutting tool performs preliminary scoring or grooving of the insulating material along the desired hole perimeter. This preliminary action guides the subsequent cutting path and ensures accurate hole dimensions by establishing precise boundaries before removing the material core.
Solution Approach 2:
The patent introduces an intermediary support structure with a passage hole that guides the cutting tool. This support acts as a template or mold, ensuring that the cut hole matches the precise dimensions and shape of the passage hole in the support, thereby achieving accurate dimensional control.
3Productivity
If cutting blades work directly on the conveyor belt, then cutting speed is maintained, but the conveyor belt is damaged by incisions
Solution Approach 1:
The patent introduces a removable support structure with a passage hole as an intermediary between the cutting tool and the conveyor belt. The cutting tool cuts through the insulating material while guided by this support, preventing direct contact with the conveyor belt and thus avoiding incisions and damage to the belt while maintaining cutting efficiency.

AI summary
The invention relates to a cutting method for forming a through-hole passing through an insulating material part (5) comprising: placing the insulating material part (5) against a holder (11) having a support surface provided with a passage hole (18), arranging a cutting tool (15) that has a cutting edge facing the insulating material part, translatably guiding the cutting tool in a through-direction (19), and pushing the cutting tool in the through-direction until the cutting edge reaches the passage hole so that the cutting tool passes through a density of the insulating material part located between the second end surface and the first end surface of the insulating material part while imposing a vibratory motion on the cutting tool (15) all the while it is passing through the insulating material part. The insulating material part (5) can be made of glass wool.
