Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing duct manufacturing equipment faces challenges in improving cutting and forming quality while reducing processing time, as increasing production speed deteriorates quality and reducing roller speeds decreases efficiency, and the fixed extrusion length of rollers leads to unnecessary rotation areas and overstroke, affecting production speed.
Innovation Solution
A duct cutting and forming apparatus with a rotation housing and eccentric housing system, where the eccentric drive reciprocates the eccentric housing within 180 degrees, allowing adjustable extrusion length and faster restoration speeds, optimizing the cutting and forming process by controlling the number of reciprocations and rotation speeds of the cutting and forming rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rotation speed of the rotation housing is increased to improve production speed, then productivity increases, but the extrusion speed of the cutting roller and forming roller increases, deteriorating cutting and forming quality
Solution Approach 1:
The patent divides the rotation drive into two independent parts: the rotation housing rotation drive and the main shaft rotation drive. This segmentation allows independent control of production speed (rotation housing speed) and quality (roller extrusion speed), resolving the contradiction between productivity and manufacturing precision.
Solution Approach 2:
The patent introduces adjustable extrusion length for the cutting roller and forming roller, allowing dynamic optimization of the extrusion stroke. This enables the system to adapt extrusion parameters to actual processing needs, improving quality while maintaining high production speed.
2Productivity
If the extrusion length of the cutting roller and forming roller is increased to secure production yield, then productivity improves, but the rotation area required increases, reducing actual cutting and forming efficiency
Solution Approach 1:
The patent makes the extrusion length of the cutting roller and forming roller adjustable rather than fixed. This allows optimization of extrusion stroke to match actual processing requirements, eliminating unnecessary over-stroke and reducing idle rotation time while maintaining sufficient production yield.
Solution Approach 2:
The patent changes the extrusion length parameter of the rollers from a fixed value to an adjustable parameter. This enables fine-tuning of the extrusion stroke to achieve optimal balance between production yield and processing time, eliminating waste from excessive extrusion length.
