Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In synchronous cutting machines, large diameter combined grooving blades with deep slits face heat-related rigidity issues, leading to decreased cutting efficiency and shortened tool life due to inadequate cooling, which increases costs when trying to maintain substrate rigidity by increasing substrate height.
Innovation Solution
A combined grooving blade design with half-closed water cooling channels, featuring uniformly distributed cooling water through holes and channels with graded widths on outside diamond grooving blades and internal clamp plates, allowing continuous cooling and heat dissipation, even in deep slits, by connecting water channels across the grooving blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the diameter of the combined grooving blade and the depth of the slits are increased, then the cutting capability is improved, but the temperature of the steel substrate increases greatly and the substrate is easily deformed
Solution Approach 1:
The patent implements a water cooling system with cooling water channels formed by the clamp plates and cooling water through-holes in the grooving blades, allowing cooling water to flow through and dissipate heat generated during cutting operations, thereby controlling substrate temperature while maintaining large blade diameter and deep slit capabilities
Solution Approach 2:
The patent transitions from external surface cooling to internal volumetric cooling by creating three-dimensional cooling water channels within the blade structure itself, enabling cooling water to reach the core heat generation zones deep within the slits and at the blade-substrate interface
2Strength
If the height of the steel substrate is increased to maintain the rigidity of the substrate, then the rigidity is improved, but the cost of the steel substrate and the power consumption of the device are greatly increased
Solution Approach 1:
The water cooling system actively removes heat during cutting operations, preventing thermal softening and deformation of the substrate, thereby maintaining substrate rigidity and dimensional stability without requiring excessive substrate height or material quantity
Solution Approach 2:
The patent changes the thermal parameters of the cutting process by introducing active cooling, which alters the temperature field distribution in the substrate, allowing thinner substrates to maintain rigidity under cutting loads by preventing thermal-induced softening
3Temperature
If external watering is applied during cutting operation, then cooling is provided, but the water cannot enter to the inside of slits and the cooling effect is insufficient
Solution Approach 1:
The patent creates internal cooling water channels within the blade structure and positions cooling water through-holes to enable three-dimensional water distribution, allowing cooling water to penetrate deep into the slits and reach internal heat generation zones that external surface watering cannot access
Solution Approach 2:
The cooling water channels are nested within the blade structure, with the clamp plates forming channels that contain and direct cooling water flow through the blade assembly, creating a compact integrated cooling system where cooling infrastructure is embedded within the cutting tool itself

AI summary
Disclosed is a combined grooving blade for a synchronous cutting machine with half-closed water cooling channels. Two outside diamond grooving blades (1) are disposed on outer sides of two internal clamp plates (2). The two outside diamond grooving blades (1), the two internal clamp plates (2) and a central diamond grooving blade (3) are fixed into a whole by fasteners (7). A plurality of cooling water through holes (5) are uniformly distributed, along the same circumference, on each of the outside diamond grooving blades (1). Cooling water channels (6) are provided on the internal clamp plate (2) and in positions corresponding to the cooling water through holes (5) on the outside diamond grooving blade (1). The cooling water channels (6) are distributed in the radial direction of the outside diamond grooving blade (1). Ends of some of the cooling water grooves (6) are in communication with edges of outer circles of the internal clamp plates (2) via gaps. According to the combined grooving blade for a synchronous cutting machine with half-closed water cooling channels, grooving blades are cooled by water in the cooling water channels and water flowing from the cooling water channels so as to achieve a good heat dissipation effect, thereby improving the cutting efficiency and prolonging the service life.
