Opposite-Direction Oil Application for Thin Metal Plates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machining oil application methods risk uneven distribution and plate crinkling when applying oil to extremely thin metal plates, making it difficult to convey them to press apparatuses without damage.
Innovation Solution
A machining oil applying apparatus with upper and lower surface units, reciprocally moving in opposite directions perpendicular to the plate's conveying direction, ensures even oil distribution and prevents plate bending by canceling out forces on both surfaces, while also allowing for uniform oil application and reduced oil usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a member impregnated with liquid machining oil is placed in contact with the thin plate and moved across the surface, then machining oil is applied onto the thin plate, but the thin plate becomes crinkled in the direction of movement when the plate thickness is 0.3 mm or below
Solution Approach 1:
The single applying unit is divided into two separate units: an upper surface applying unit for applying machining oil to the upper surface of the thin plate, and a lower surface applying unit for applying machining oil to the lower surface. This segmentation allows independent control of each unit, enabling the lower surface unit to counteract crinkling forces while the upper surface unit applies oil uniformly.
Solution Approach 2:
The lower surface applying unit acts as a counterbalancing mechanism that moves in the opposite direction to the upper surface applying unit. When the upper surface unit causes plate deformation during oil application, the lower surface unit simultaneously applies counteracting force in the opposite direction, neutralizing the crinkling effect on extremely thin plates (0.3 mm or below).
2Quantity of substance
If the amount of machining oil used to impregnate the member is reduced to economize on machining oil, then cost is reduced, but the machining oil becomes unevenly distributed within the member resulting in oil being applied to only some parts of the thin plate
Solution Approach 1:
By dividing the oil application function into upper and lower surface units, the system can achieve complete surface coverage even when each unit contains less oil. The two units work together to distribute oil uniformly across both surfaces of the plate, compensating for reduced impregnation quantity in each individual unit.
Solution Approach 2:
The invention transitions from single-sided oil application to dual-sided application. By applying machining oil from both the upper and lower surfaces of the thin plate, the system achieves more uniform overall distribution and complete coverage, allowing each applying unit to use less oil while maintaining or improving total distribution uniformity.

Function Achieved in This Case
Enables reliable machining oil application and plate conveyance without crinkling, even with reduced oil amounts, and allows for cost-effective maintenance by replacing only worn-out oil-impregnated members, ensuring efficient and uniform oil distribution across the plate surface.
Implementation Method 1
an applying unit moving portion that causes the upper surface applying unit and the lower surface applying unit to move reciprocally in a direction that is perpendicular to a conveying direction of the thin plate, wherein the applying unit moving portion causes the upper surface applying unit and the lower surface applying unit to always move in respectively opposite directions
Implementation Method 2
an upper surface applying unit that is impregnated with the machining oil, contacts an upper surface of the thin plate and applies the machining oil onto the upper surface of the thin plate
Implementation Method 3
a member that has been impregnated with liquid machining oil in contact with the thin plate to apply the machining oil
