Magnetic Chip Discharge Path With Withdrawn Support Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for magnetic-belt chip conveyors do not effectively reduce the quantity of coolant discharged with chips, leading to inefficient coolant recovery and increased material and design complexities.
Innovation Solution
The method involves deflecting the return flow out of the discharge path and temporarily withdrawing the supporting surface from the discharged chips, creating a jumping movement that enhances coolant release, thereby reducing the amount of coolant carried with chip accumulations and optimizing the discharge path parameters such as width, gradient, and magnet spacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the discharge region is made longer to improve coolant release, then coolant recovery improves, but material requirement and footprint increase
Solution Approach 1:
The patent introduces a movable support surface that can be temporarily withdrawn from under the chip accumulations during discharge. This dynamic element allows the system to change its configuration during operation - providing support when needed and removing it to enhance coolant release, thereby achieving better coolant recovery without requiring a longer fixed discharge region structure
Solution Approach 2:
The support surface is periodically withdrawn and repositioned during the chip discharge process. This periodic action creates intermittent free-fall phases for the chip accumulations, which enhances coolant release at critical moments without requiring the discharge region to be continuously extended in length
2Loss of energy
If the conveying speed is increased to improve coolant release, then coolant recovery improves, but the time available for return flow decreases
Solution Approach 1:
The periodic withdrawal of the support surface creates intermittent acceleration phases that enhance coolant release at specific moments during the discharge cycle. This allows effective coolant separation without requiring continuously high conveying speeds, thereby preserving adequate time for coolant return flow
Solution Approach 2:
The system dynamically changes the conveying parameters by temporarily increasing speed during the support withdrawal phase and reducing it during the return flow phase. This variable speed approach optimizes coolant release when needed while maintaining sufficient time for coolant recovery overall
3Loss of energy
If magnets are spaced closer together to reduce chip accumulation cross section, then coolant release improves, but the number of magnets and material expenditure increase
Solution Approach 1:
The movable support surface creates dynamic discharge conditions that enhance coolant release without requiring increased magnet density. By temporarily removing support during discharge, the system achieves effective coolant separation using the existing magnet spacing, avoiding the need to install additional magnets
4Weight of stationary object
If the discharge path width is reduced to lower material expenditure, then manufacturing cost decreases, but conveying capacity is limited
Solution Approach 1:
The movable support surface allows the discharge path to dynamically adapt its effective width. During normal operation, the full width is available for conveying. During discharge phases, the support withdrawal enhances coolant release across the available width, maximizing the utility of the reduced- width structure
