Ceramic Honeycomb Cutting Synchronization Prevents Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceramic molded body cutting apparatuses risk deformation or cracking, especially when cutting honeycomb structures with thin walls, due to contact between the cutting piece and the molded body during the cutting process, and adherence of material to the cutting piece can lead to clogged cells and defective cuts.
Innovation Solution
A molded body cutting apparatus is designed with a first conveyer member and a cutting member that move in synchronization, and a second conveyer member, where the conveyance and cutting speeds are adjusted to prevent contact and adherence, using a filamentous cutting member, such as a metallic filament coated with resin, to minimize stress and facilitate precise cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cutting piece simply rises back to its original position after cutting, then the cutting operation can proceed to the next cycle, but the cutting piece and the cut molded body may make contact causing deformation, cracking, or cell wall damage
Solution Approach 1:
The cutting piece is designed to move dynamically in three directions: horizontally along with the molded body during cutting, vertically downward to perform the cut, and horizontally backward after cutting. This dynamic multi-directional movement prevents contact between the cutting piece and the cut molded body while maintaining high cutting cycle speed.
2Ease of manufacture
If the cutting piece contacts the molded body during rising, then the cutting operation can be completed, but constitution material adheres to the cutting piece and re-adheres to the cut face causing defects
Solution Approach 1:
The cutting piece performs a horizontal backward movement after cutting completes, creating separation distance between the cutting piece and the cut molded body. This dynamic separation prevents constitution material from re-adhering to the cut face, ensuring cut face cleanliness while completing the cutting operation.
3Device complexity
If a traditional cutting piece is used, then the cutting apparatus is simple, but the cell walls of honeycomb molded bodies suffer deformation, cracking, or clogging
Solution Approach 1:
The cutting piece is designed with dynamic multi-directional movement capability, moving horizontally along with the molded body during cutting, vertically downward to cut, and horizontally backward after cutting. This dynamic movement pattern prevents contact with the cut molded body and cell structures, preserving cell wall integrity while maintaining a relatively simple apparatus structure.
4Ease of operation
If the conveyance speed and cutting speed are not synchronized, then the cutting operation is simpler to control, but the cut face becomes uneven and deformation occurs
Solution Approach 1:
The cutting piece moves horizontally along with the molded body at the same speed during the cutting operation, maintaining relative position stability. This synchronized dynamic movement ensures the cut face remains flat and prevents deformation, while the automated speed coordination simplifies the control mechanism.
