Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring apparatuses for welded billets in continuous rolling processes face issues such as frequent maintenance due to heat exposure, durability problems, and difficulty in accessing and replacing cutting tools, leading to increased maintenance costs and potential defects in rolled materials.
Innovation Solution
A deburring apparatus with rotatable arms supporting idle cutting disks that move away from the billet's heat when not in use, featuring adjustable and accessible cutting tools, and integrated cleaning mechanisms to reduce maintenance disruptions and improve productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cutting means are positioned close to the billet surface during stand-by, then the apparatus is ready for immediate operation, but the cutting means are exposed to continuous heat radiation causing durability problems and frequent maintenance
Solution Approach 1:
The cutting means are mounted on rotatable arms that can dynamically adjust their position between a stand-by position (close to the billet for quick operation) and a retracted position (away from heat radiation). This dynamic positioning system allows the apparatus to optimize between productivity and reliability based on operational needs.
Solution Approach 2:
The cutting means are exposed to heat radiation only periodically during actual cutting operations, rather than continuously during stand-by periods. The rotatable arms periodically retract the cutting means away from the billet when not in use, minimizing heat exposure and extending the lifespan of the cutting tools.
2Adaptability or versatility
If multiple cutting means are installed to cover all billet faces, then complete deburring is achieved, but the device complexity and total weight increase significantly
Solution Approach 1:
Each cutting disk is designed with a large diameter to serve multiple functions - it can deburr different faces of the billet by rotating the supporting arms to different angular positions. The cutting disks act as universal tools that can handle various deburring positions, reducing the total number of cutting means required.
Solution Approach 2:
The solution adds the angular dimension of rotation to the positioning system. Instead of having separate cutting means for each face, the arms can rotate to different angles, allowing a single set of cutting disks to service all billet faces by operating in three-dimensional space rather than fixed positions.
3Manufacturing precision
If the cutting means are positioned in narrow space close to the billet, then deburring precision is improved, but access for cleaning and maintenance becomes difficult
Solution Approach 1:
The rotatable arm mechanism provides dynamic accessibility - the cutting means can be rotated into position for precise deburring operations, then rotated away to accessible positions for cleaning and maintenance. This dynamic positioning allows the system to alternate between precision operation mode and maintenance mode.
Solution Approach 2:
The design anticipates maintenance needs by providing preliminary access paths. The rotatable arms can be positioned in advance to allow cleaning operations to be performed on the cutting means before they are installed in the narrow working space, or the arms themselves can be rotated to expose the cutting means for cleaning during maintenance intervals.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution extends the lifespan of deburring equipment, reduces maintenance costs, and allows for quicker tool changes without production interruptions, enhancing the efficiency and reliability of the deburring process.
Implementation Method 1
The disks are located such that the reaction force that the cutting disk encounters when contacting the burr provokes the rotation of the disk.

AI summary
An apparatus for removing burrs on billets has a supporting element and at least two arms extending from the supporting element. Deburring devices are driven in rotation by burrs of billets. The deburring devices are supported by the arms. The apparatus is driven rotatably and reversibly by a drive between a stand-by position wherein the apparatus is spaced apart from the billet to be deburred and a working position wherein the deburring devices are close to the billet to be deburred and are able to contact a burr.
