Cutting Head With Tilted Circular Blade For Large Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting heads for cutting-off machines are inadequate for cutting large-section profiles with main horizontal or vertical extensions, as increasing the diameter of the circular blade is limited by operational and construction requirements, and prior solutions do not effectively address the cutting needs for such profiles.
Innovation Solution
A cutting head with a circular blade that can tilt between 0° and 45° and move along a rectilinear path, allowing it to assume four positions at the vertices of an ideal quadrilateral, enabling effective cutting of large-section profiles by adjusting its inclination and position to accommodate both horizontal and vertical extensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the diameter of the circular blade is increased to cut large-section profiles, then the cutting capability is improved, but the operational and construction requirements cannot be met beyond certain limits
Solution Approach 1:
The cutting head incorporates a blade inclination unit that enables dynamic adjustment of the circular blade's inclination angle between 0° and 45° relative to the workpiece. This dynamic positioning capability allows the same blade to effectively cut profiles of varying sizes and orientations without requiring multiple blades of different diameters, thereby resolving the contradiction between cutting capability and device complexity
Solution Approach 2:
The invention introduces a new degree of freedom by tilting the blade along an inclination axis perpendicular to both the blade rotation axis and the workpiece rotation axis. This dimensional change transforms the cutting approach from a single-plane operation to a multi-angle operation, enabling effective cutting of large-section profiles without increasing blade diameter
2Ease of operation
If the circular blade is tilted with upward or downward movement, then cutting of profiles is achieved, but the cutting diagram is inadequate for large-section profiles with main horizontal or vertical extension
Solution Approach 1:
The cutting head is designed with universal adaptability to handle both horizontally extending and vertically extending large-section profiles through the combination of workpiece rotation about a first axis and blade inclination about a perpendicular axis. This multi-functional capability allows the same cutting head to effectively process various profile orientations and sizes, resolving the inadequacy of previous cutting diagrams
3Productivity
If the circular blade is moved in a rectilinear path perpendicular to the profile, then cutting is performed, but the cutting diagram remains inadequate for large-section profiles
Solution Approach 1:
The system employs dynamic coordination between the rectilinear feeding movement of the blade and the inclination angle adjustment. The blade can be fed in a rectilinear path while simultaneously being inclined at optimized angles (0° to 45°) depending on the profile orientation, maintaining cutting efficiency while adapting to large-section profiles of various dimensions

AI summary
A cutting head (1) for a cutting-off machine (100) comprises a bearing base (10), a support structure (20) mounted to the bearing base (10) to rotate about a rotation axis (Z-Z), a cutting unit (30) with a circular blade (31) rotating about a rotation axis (A-A), said cutting unit (30) being mounted to tilt about a tilt axis (U-U), parallel to the rotation axis (A-A) of the circular blade (31) between a rest position and a cutting position, a circular blade inclination unit (40), which is coupled to the cutting unit (30) to incline the cutting unit (30) about an inclination axis (Y-Y) and a blade feeding unit (50), fixed to the support structure (20) and coupled to the blade inclination unit (40) to move the cutting unit (30) along a rectilinear feeding direction (V-V), which is parallel or coincident with the inclination axis (Y-Y), between a first travel limit position and a second travel limit position.
