Variable Guide Distance Cutting Machine for Precision Metal Shaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting machines struggle to achieve high precision in cutting metal members, particularly in shaping the configuration of short pieces for forging, as they fail to maintain a predetermined cut surface angle and smoothness due to fixed guide distances.
Innovation Solution
A cutting machine with a disc-like tool and two pairs of guides, where the distance between the guides is variable, allowing the work to pass between them, thereby reducing deflection and enabling precise cutting by adjusting the guide distance according to the work's configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distance between the two pairs of guides is fixed to be sufficiently large to accommodate the maximum diameter of the work, then the work can pass between the guides, but the distance between the cutting position and the guides increases, causing increased deflection in the axial direction of the disc-like tool
Solution Approach 1:
The distance between the two pairs of guides is made variable rather than fixed. The guides can be adjusted to change their separation distance, allowing the system to adapt to different workpiece diameters while maintaining optimal cutting precision for each specific configuration
Solution Approach 2:
The physical parameter of guide distance is changed from a fixed value to a variable parameter. By adjusting the separation distance between guides based on the specific workpiece being cut, the system optimizes both adaptability and cutting precision for different work configurations
2Manufacturing precision
If the distance between the two pairs of guides is reduced to minimize deflection, then cutting precision improves, but the work with larger diameter cannot pass between the guides
Solution Approach 1:
The guide system incorporates dynamic adjustability, allowing the distance between guides to be changed based on the specific workpiece requirements. This enables the system to achieve minimal guide distance for precision cutting when needed, while still accommodating larger workpieces by increasing the distance
3Adaptability or versatility
If the guides are positioned far from the cutting position to accommodate various work sizes, then all work can pass between the guides, but deflection in the axial direction of the disc-like tool increases, reducing cutting precision
Solution Approach 1:
The guide distance parameter is made adjustable rather than fixed. By changing this parameter based on the specific workpiece being cut, the system can position guides close to the cutting position for high precision work while still accommodating various work sizes through parameter adjustment

AI summary
A cutting machine (1) has a disc-like tool (2), a saw head (10), two pairs of guides (3, 4) and a variable device (1a). The disc-like tool (2) has two sides. The saw head (10) rotatably supports the disc-like tool (2). The two pairs of guides (3, 4) are provided on the saw head (10), and the guides (3, 4) of each pair face the two sides of the disc-like tool (2). The variable device (1a) varies a distance between the two pairs of guides (3, 4) so that work (20) can pass between the two pairs of guides (3, 4) when the work (20) is to be cut by the disc-like tool (2).
