Sliding Guide Annular Nozzle for Tool Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for processing glass panes with sliding guides and hydraulic cushions face increased design complexity and inadequate tool cooling, as only partial hydraulic pressure reaches the tool, limiting machining performance.
Innovation Solution
A sliding guide with an annular nozzle aligned radially inward towards the tool ensures surface-friendly guidance and effective tool cooling by allowing hydraulic fluid to flow towards the tool, mixing with air to improve friction conditions and prevent radial liquid escape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If hydraulic cushions are built up on both sides of the workpiece plate for surface-friendly guidance, then the workpiece plate can be guided without damaging the surface, but the design complexity increases and the tool cooling becomes insufficient
Solution Approach 1:
The invention extracts the hydraulic cushioning function from both sides and concentrates it on only one side (the side with the sliding guide). The other side uses simple mechanical support elements, thereby reducing design complexity while still protecting the coated surface from damage during machining.
Solution Approach 2:
The hydraulic fluid serves multiple functions: it creates the hydraulic cushion for surface-friendly support AND it cools the tool through the gap between the slideway and workpiece plate. This multi-functionality resolves the contradiction by eliminating the need for separate cooling systems.
2Object-affected harmful factors
If hydraulic fluid is used to build up hydraulic cushions for guiding the workpiece plate, then the surface is protected from damage, but the tool cooling becomes insufficient because only part of the hydraulic pressure reaches the tool
Solution Approach 1:
The hydraulic fluid is designed to perform dual functions: supporting the workpiece plate via hydraulic cushion AND cooling the tool. The fluid flows through the gap between the slideway and workpiece plate, directly cooling the tool while maintaining the hydraulic cushion for surface protection.
Solution Approach 2:
The gap between the slideway and workpiece plate acts as an intermediary channel that directs the hydraulic fluid flow toward the tool. This intermediary structure enables the hydraulic fluid to reach the tool for cooling while still maintaining the hydraulic cushion for surface-friendly guidance.
3Measurement precision
If a sliding guide with hydraulic cushion is used for precise guidance, then the workpiece plate can be guided precisely, but the structure becomes more complex compared to simple mechanical support
Solution Approach 1:
The invention uses a hydraulic cushion between the slideway and workpiece plate to achieve precise guidance. The hydraulic fluid pressure creates a thin film that eliminates mechanical contact, providing precise guidance while reducing friction and wear compared to traditional mechanical support systems.
