Laser Machining Support Dross Removal With a Rotating Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser beam machining technologies face challenges in efficiently and reliably removing dross from the support after machining a plate material, which can lead to welding of the dross with the next plate material, reducing machining accuracy, and increasing the frequency of support replacement.
Innovation Solution
A method and apparatus that utilize a rotating tool to contact and remove dross from the support, reducing the burden on operators and minimizing the frequency of support replacement by ensuring reliable dross removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a laser beam is used to machine plate material, then machining efficiency is improved, but dross adheres to the support causing welding with next plate material and reducing machining accuracy
Solution Approach 1:
The patent applies preliminary action by removing dross from the support immediately after laser machining completes, before the next plate material is positioned. The rotating tool is brought into contact with the support to remove adhered dross in advance, preventing potential welding with the next workpiece and maintaining machining accuracy without interrupting the overall production flow.
2Duration of action of stationary object
If dross is not removed from the support, then support replacement frequency increases, but manual dross removal increases operator burden
Solution Approach 1:
The system applies self-service by automatically removing dross from the support using a rotating tool that is integrated into the machining apparatus. The control unit automatically controls the rotating tool to contact the support and remove dross without operator intervention, reducing the operator burden while extending support usage duration by preventing dross accumulation.
3Reliability
If a rotating tool is brought into contact with dross to remove it, then dross removal reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the dross removal function with the existing laser machining apparatus by integrating a rotating tool into the same system. The rotating tool is positioned to contact the support after laser machining, and the control unit coordinates both the laser beam and rotating tool operations, combining multiple functions into one apparatus to reduce overall system complexity while maintaining reliable dross removal.
