Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flying saws are expensive to create and suffer from contamination of the drive system by coolant and chips, which complicates maintenance and operation.
Innovation Solution
A flying saw design featuring guide rails and a travel drive positioned above the sawing device to prevent contamination, with a portal structure supported by crossbeams and a detachable sawing device for easy replacement, along with a vortex separating device and electromagnetic levitation drive for precise movement and reduced friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a machine bed with rack and pinion drive is used, then the sawing device can be moved along the machine bed, but the drive is exposed to contamination from chips and coolant
Solution Approach 1:
The patent inverts the conventional arrangement by positioning the guide rails and travel drive above the sawing device instead of below. This inversion places the drive mechanism in a clean, dry area away from the cutting zone, preventing contamination by coolant and chips while maintaining reliable operation
Solution Approach 2:
The drive system is extracted from the traditional machine bed structure and repositioned to a separate location above the sawing device. This separation removes the drive from the harmful environment of coolant and chip contamination, allowing independent maintenance and operation
2Reliability
If a complex machine bed structure is created, then the sawing device can be properly supported and driven, but production costs increase significantly
Solution Approach 1:
The machine bed is segmented into functional modules: guide rails mounted on the machine bed, crossbeams that can be moved independently, and a sawing device mounted on the crossbeams. This modular segmentation simplifies manufacturing while maintaining structural integrity and support functionality
Solution Approach 2:
The crossbeams serve multiple functions: they connect to the guide rails for movement, support the sawing device, and provide a mounting structure for the frame element. This multi-functionality reduces the need for additional supporting structures, lowering production complexity
3Stability of the object's composition
If the sawing device is fixed to the frame element, then structural stability is improved, but replacement and maintenance become difficult
Solution Approach 1:
The connection between the sawing device and frame element is made dynamically adjustable through threaded spindles that allow the sawing device to be securely fixed during operation yet easily removed when needed. This dynamic connection maintains stability during cutting while enabling simple maintenance
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 design minimizes production effort, prevents drive contamination, and enables efficient cutting with reduced vibrations and improved accessibility for tool maintenance, while allowing for precise positioning and high acceleration of the sawing device.
Implementation Method 1
the at least one travel drive is an electromagnetic levitation drive. In this case, the crossbeam on the portal is designed in the manner of an electromagnetic levitation system, in which the attractive forces of electromagnets or permanent magnets carry and guide the crossbeam on the two guide rails
Implementation Method 2
the sawing device is formed by a vortex separating device. This enables an effective cutting process for cutting profile or tube material to length. In addition, such a vortex separating device can be implemented in a compact design, as a result of which centrifugal forces can be reduced and acceleration processes can be optimized
