Spray Nozzle Diffusion Member for Press Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing press apparatuses for forming steel sheets have a limited coolant diffusion angle due to small spray nozzle designs, leading to poor cooling efficiency and increased costs when attempting to improve shape accuracy, which affects the durability and cost of the equipment.
Innovation Solution
A press apparatus with a spray nozzle featuring a nozzle main body and a diffusion member inside the through-hole, where the diffusion member includes a protruding portion that diffuses coolant and a retaining portion to prevent slippage, allowing for a larger diffusion angle and improved cooling efficiency without increasing the cost of the nozzle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the shape accuracy within the spray nozzle is increased to increase the diffusion angle of coolant, then the cooling efficiency is improved, but the cost of the spray nozzle increases and durability becomes a concern
Solution Approach 1:
The spray nozzle is divided into two functional parts: a simple nozzle main body and a separate diffusion member. The diffusion member includes a diffusing portion with multiple protrusions that create coolant diffusion, and a retaining portion that secures it inside the nozzle. This segmentation allows the nozzle main body to remain simple and inexpensive while the diffusion member provides the required diffusion function.
Solution Approach 2:
The diffusion member acts as an intermediary element inserted into the nozzle passage. It has protrusions that extend into the coolant flow path, interfering with the flow to create diffusion patterns. This intermediary structure achieves the diffusion function without requiring complex internal geometry of the nozzle itself, thereby maintaining manufacturing simplicity and cost-effectiveness.
2Productivity
If a diffusion member is added to increase coolant diffusion angle, then cooling efficiency is improved, but the device complexity increases
Solution Approach 1:
The diffusion function is segmented from the nozzle structure and implemented through a separate diffusion member. This member consists of simple geometric elements (protrusions and retaining portions) that can be easily manufactured and assembled, avoiding complex integrated designs while achieving improved cooling efficiency through increased coolant diffusion angle.
3Temperature
If the diffusion angle of coolant is increased to improve cooling efficiency, then the cooling performance is enhanced, but the shape accuracy and manufacturing cost of the nozzle must be increased
Solution Approach 1:
The diffusion member serves as an intermediary component that achieves the desired coolant diffusion angle without requiring high shape accuracy in the nozzle main body. The protrusions on the diffusion member are designed to interfere with coolant flow and create diffusion patterns, achieving enhanced cooling performance while keeping the nozzle main body simple and easy to manufacture.

Function Achieved in This Case
The solution enhances the coolant diffusion angle, improving cooling efficiency and reducing equipment costs by using a cost-effective diffusion member, such as a split pin, which maintains the diffusion member in place and ensures effective coolant distribution.
