Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for processing section bars with annular or shaped cross-sections face productivity issues due to manual swarf removal, leading to swarf dispersion in the environment.
Innovation Solution
The machine incorporates roller support devices with movable rollers, a processing station with a milling unit, and a combination of blowing and suction devices to automatically remove swarf, ensuring it does not disperse and maintain high productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual swarf removal is used, then the machine structure is simple, but productivity is reduced and swarf disperses in the environment
Solution Approach 1:
The swarf removal system is segmented into distinct functional components: blowing devices positioned at the processing station and suction devices positioned along the base. This segmentation allows each component to perform its specific function efficiently while maintaining overall system simplicity. The blowing device generates airflow to move swarf, while suction devices capture and contain it, together resolving the productivity-environmental dispersion contradiction.
Solution Approach 2:
Air flow acts as an intermediary medium between the processing operation and swarf containment. The blowing device generates air flow that carries swarf particles, and suction devices capture this air-swarf mixture. This intermediary approach enables automatic swarf removal without complex mechanical contact with the workpiece, thereby improving productivity while preventing environmental dispersion.
2Object-generated harmful factors
If automatic swarf removal is implemented, then productivity increases and swarf dispersion is limited, but device complexity increases
Solution Approach 1:
The harmful factor of swarf dispersion is extracted and separated from the processing environment through the suction devices. These devices are positioned to capture swarf at its source and remove it from the workspace, effectively taking out the environmental pollution problem. The blowing device works in conjunction to direct swarf toward suction points, together eliminating dispersion while maintaining relatively simple system architecture.
Solution Approach 2:
The swarf removal system operates autonomously without requiring manual intervention. The blowing and suction devices work automatically during the processing cycle, with air flow naturally carrying swarf from the processing area to suction points. This self-service operation prevents environmental dispersion while avoiding the need for complex control systems or manual monitoring.
3Loss of time
If manual swarf removal is used, then device complexity is low, but time is lost and productivity is reduced
Solution Approach 1:
The automatic swarf removal system operates continuously throughout the processing cycle without interruption. The blowing device maintains constant air flow to move swarf, while suction devices continuously capture and contain it. This continuous operation eliminates the time losses associated with manual swarf removal intervals, thereby improving productivity while using a relatively simple system architecture.
