Workpiece Lubricator Baffle Plate Spray Jet Width Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workpiece oilers using single-component nozzles result in uneven distribution of lubricating agents across the workpiece, with higher greasing density in lateral areas and insufficient coverage in edge areas due to larger droplets and reduced spray energy.
Innovation Solution
A device is arranged in front of the single-component nozzle to limit the expansion of the spray jet, using baffle plates to cut off the outermost lateral areas of the spray jet, ensuring a uniform distribution by allowing only the central area to reach the workpiece, with adjustable baffle placement to accommodate different greasing agents and workpiece sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-component nozzle is used to spray lubricating agent, then the spray structure is simple and no mist is formed, but the distribution of lubricating agent becomes uneven across the workpiece width
Solution Approach 1:
The spray jet is segmented into a central area and lateral areas by the baffle plates. The baffle plates divide the spray pattern, allowing only the central area to reach the workpiece while blocking the lateral areas, thereby achieving uniform distribution across the workpiece width.
Solution Approach 2:
The harmful lateral portions of the spray jet are extracted and removed by the baffle plates. The baffle plates cut off the outermost lateral areas of the spray jet, preventing these excessive droplets from striking the workpiece and causing uneven greasing.
2Manufacturing precision
If baffle plates are added to limit spray jet expansion, then distribution uniformity is improved, but device complexity increases
Solution Approach 1:
The baffle plates are positioned at specific locations to create a slot-shaped free area that allows the central spray area to pass through while blocking lateral areas. This localized intervention achieves uniform distribution without requiring complete redesign of the entire spray system.

Function Achieved in This Case
This solution achieves a uniform distribution of the lubricating agent across the workpiece width and length, preventing excessive greasing in edge areas and ensuring consistent application, thereby improving the quality of stamped and formed components and extending tool service life.
Implementation Method 1
A device for limiting the expansion of the spray jet, in particular the width of the spray jet, is arranged in front of and at a distance from the single-component nozzle in the spraying direction
Implementation Method 2
the remainder of the spray jet passing between the device for limiting the expansion of the spray jet has an advantageous, approximately uniform distribution of lubricating agent
