Honeycomb Dried Body Cutting Force Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for cutting honeycomb dried bodies often result in cracks, especially when using a wheel grindstone, due to increased processing resistance and abrasive grain wear, which affects yield, cost, and production efficiency, particularly for large-sized honeycomb structures.
Innovation Solution
A cutting method and device that applies a resisting force (Pm) to the cutoff section during cutting, balancing it with the thrust force (Pt) and weight (Pw) of the cutoff section, to prevent movement and crack generation, ensuring the honeycomb dried body is cut without peeling off the product section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wheel grindstone is used to cut the honeycomb dried body, then the cutting can be performed, but cracks are generated in the product section when the grindstone is used for a long period or at high cutting speeds
Solution Approach 1:
The invention applies a supporting force to the cutoff section before and during cutting to prevent it from moving. This preliminary counteraction to the expected movement (caused by thrust force and weight) prevents the chain reaction that would cause peeling and cracks in the product section. By anticipating and counteracting the problematic movement in advance, the system maintains cutting speed while preventing defects.
2Duration of action of moving object
If the wheel grindstone is used continuously for a long period, then production efficiency is maintained, but abrasive grains wear and processing resistance increases leading to crack generation
Solution Approach 1:
The supporting force applied to the cutoff section counteracts the increased processing resistance that occurs during prolonged grindstone usage. By stabilizing the cutoff section against movement caused by wear-induced resistance increases, the system maintains cutting precision throughout the grindstone's service life without generating cracks in the product section.
3Productivity
If the cutting speed is raised to enhance production efficiency, then productivity increases, but processing resistance becomes large and cracks are easily generated
Solution Approach 1:
The supporting force applied to the cutoff section counteracts the increased processing resistance that occurs at higher cutting speeds. By preventing the cutoff section from moving despite the higher resistance forces, the system enables high-speed cutting without generating cracks in the product section, thus maintaining both productivity and precision.
4Volume of stationary object
If a large-size honeycomb dried body is cut, then the filter and catalyst are enlarged as required, but the cutoff section weight increases making cracks more easily generated
Solution Approach 1:
The supporting force is applied to the cutoff section to counteract its weight before cutting begins. This preliminary counteraction prevents the weight-induced movement that would cause peeling and cracks in the product section, enabling the cutting of large-size honeycomb bodies without compromising precision despite the increased gravitational forces.

Function Achieved in This Case
This approach effectively prevents crack generation in the honeycomb dried body, extends the life of the grindstone, and enhances cutting efficiency, even for large-diameter honeycomb structures, by ensuring the cutoff section remains immobile during cutting.
