Adapter Sleeve Cooling Channels for Faster Tool Coolant Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adapter sleeves for cutting tools require additional production steps and are inefficient in coolant supply, leading to increased production effort and suboptimal cooling of cutting tools.
Innovation Solution
An adapter sleeve with a cylindrical body featuring a cooling line that decreases in flow cross-section towards the axial front end, utilizing the Venturi principle to increase coolant flow speed and efficiency, and incorporating a cooling distribution section to distribute coolant to multiple outlet nozzles, which are designed without drilling, allowing for efficient and homogeneous cooling of cutting tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If outlet nozzles are drilled into the adapter sleeve after production, then coolant can be supplied to the cutting tool, but production effort increases and coolant supply efficiency is insufficient
Solution Approach 1:
The cooling line is integrated into the adapter sleeve body during the initial production process (3D printing), rather than being added afterward through drilling. This preliminary integration eliminates the need for additional production steps and ensures optimal coolant flow paths are established before the adapter sleeve is put into service.
Solution Approach 2:
The flow cross-section of the cooling line is specifically designed to decrease toward the axial front end, creating a Venturi effect that increases coolant flow velocity. This parameter change optimizes the coolant supply efficiency while maintaining a single-integration production approach.
2Reliability
If the flow cross-section of the cooling line remains constant, then production is simpler, but coolant flow speed and cooling efficiency are insufficient
Solution Approach 1:
The cooling line's flow cross-section parameter is deliberately varied along its length, decreasing toward the axial front end to generate higher coolant velocities through the Venturi effect. This parameter variation directly improves cooling efficiency by forcing faster coolant flow over the cutting tool surfaces.
Solution Approach 2:
The cooling line design utilizes hydraulic principles, specifically the Venturi effect, where a reduction in cross-sectional area of a fluid conduit results in an increase in fluid velocity. This hydraulic principle is applied to optimize coolant delivery without requiring additional energy input or complex pumping systems.
3Reliability
If multiple cooling lines are added to cool different areas, then cooling coverage improves, but device complexity and production effort increase
Solution Approach 1:
The single cooling line is segmented into multiple outlet nozzles distributed around the adapter sleeve's circumference. Each nozzle provides localized cooling to specific areas of the cutting tool, achieving comprehensive cooling coverage while maintaining a simple single-line integration structure that is easy to manufacture.

The adapter sleeve provides economical and efficient coolant delivery to cutting tools, enhancing cooling performance by increasing coolant flow speed and ensuring homogeneous distribution, while eliminating the need for additional production steps through 3-D printing technology.
Implementation Method 1
the flow cross-section of the cooling line decreases toward the axial front end... the flow speed of the coolant changes, especially increases, due to the changing flow cross-section

AI summary
An adapter sleeve is described for inserting into an expansion chuck of a cutting device with a substantially cylindrical body that defines a longitudinal axis (L) of the adapter sleeve and a seat area for a cutting tool. The body comprises an axial front end and an axial rear end opposite the front end by means of which the adapter sleeve can be inserted into the expansion chuck of the cutting device. An outlet element is provided at the axial front end through which a coolant can be discharged toward the cutting tool. At least one cooling line extends along the body up to the outlet element and comprises a body line section and an outlet element section. At least one channel-like outlet nozzle is formed in the outlet element and is in fluidic connection with the at least one cooling line. The flow cross-section of the cooling line decreases or remains the same toward the axial front end. In addition, a cutting device is described.
