Thread-Rolling Collecting Unit for Cutting Fluid Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thread-rolling machines face issues with cutting fluid splattering onto the linking member, leading to contamination of the base and mixing with lubricating fluid, which can cause decay of the lubricating fluid and damage to the machine components.
Innovation Solution
A thread-rolling machine with a collecting unit that includes a scraping unit on the periphery of the port to scrape off cutting fluid from the linking unit during its reciprocating motion, and a collecting unit below the linking unit to collect the scraped fluid, preventing it from mixing with lubricating fluid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cutting fluid is injected to cool the thread rolling operation, then the temperature is reduced, but the cutting fluid splatters and mixes with lubricating fluid causing decay
Solution Approach 1:
The machine is divided into separate zones: a cutting fluid injection zone for cooling the thread rolling operation, and a lubricating fluid injection zone for the triggering unit. The covering unit creates physical separation between these zones, preventing mixing of the two fluids while allowing each to perform its function independently
Solution Approach 2:
The harmful splattering of cutting fluid is extracted and removed from the system by directing it away from the lubricating fluid zone. The covering unit acts as a barrier that extracts the cutting fluid from the potential mixing zone and channels it to a collection area, preventing contamination of the lubricating fluid
2Productivity
If the linking member moves at high speed for efficient thread rolling, then productivity increases, but cutting fluid splatters more extensively polluting the base
Solution Approach 1:
The covering unit acts as a flexible barrier that contains and directs the splattered cutting fluid. It allows the high-speed reciprocating motion of the linking member to continue uninterrupted while the covering unit flexes and redirects the cutting fluid away from the base, preventing pollution without restricting productivity
Solution Approach 2:
The covering unit serves as an intermediary element between the cutting fluid injection system and the base. It intercepts the splattered cutting fluid and redirects it to a collection area, mediating between the high-speed operation and the base to prevent direct contact and pollution
3Productivity
If iron chips are mixed with cutting fluid in the accommodation space, then the driving member and linking member are prone to breaking
Solution Approach 1:
Iron chips and cutting fluid are extracted from the accommodation space before they can mix with the lubricating fluid and cause damage. The covering unit creates a barrier that extracts these harmful particles from the zone where they could infiltrate between the driving member and linking member, preventing mechanical failure
Solution Approach 2:
The covering unit converts the potentially harmful splatter of cutting fluid and iron chips into a beneficial containment system. By directing the splattered mixture to a designated collection area rather than allowing it to scatter freely, the system transforms a harmful byproduct into a controlled waste stream that can be safely collected and removed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively maintains the cleanliness of the base, prevents the cutting fluid from mixing with the lubricating fluid, and ensures a long-lasting use of the lubricating fluid, thereby prolonging the service life of the machine.
Implementation Method 1
the scraping unit is in contact with the linking unit, so the cutting fluid splattered on the linking unit can be scraped off by the scraping unit when the linking unit is moved towards the accommodation space
Implementation Method 2
the scraped cutting fluid can be forced out of the covering unit, discharged into the collecting unit, and then collected

AI summary
A thread-rolling machine (3) includes a base (31), a covering unit (33), a triggering unit (32) covered by the covering unit (33), a linking unit (34) connected to the triggering unit (32), a stationary rolling die (36), and a movable rolling die (35) linked with the triggering unit (32). The covering unit (33) defines an accommodation space (331) for covering the triggering unit (32) and a port (332) adapted to bearing a reciprocating motion of the linking unit (34) . A scraping unit (333) is disposed on a periphery of the port (332). A collecting unit (37) is disposed under the linking unit (34). The collecting unit (37) is situated in the accommodation space (331) and extended beyond the covering unit (33) . Accordingly, cutting fluid splattering onto the linking unit (34) is scraped off by the scraping unit (333) and is further discharged into the collecting unit (37) for being collected, thereby keeping the base (31) clean and preventing the cutting fluid from mixing with lubricating fluid applied to the triggering unit (32).
