Removable Pipe Threader Lubrication for Low-Friction Threading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable pipe threaders often lack effective lubrication systems, leading to increased friction and heat during threading operations, with some relying on manual lubrication and others having onboard systems that may not be efficient or convenient.
Innovation Solution
A portable pipe threader with a removably coupled lubrication system that includes a reservoir and a pump powered by the drive assembly, featuring a basin with an inclined bottom to direct lubricant into the reservoir and a valve to control flow, and a stand that adjusts to funnel lubricant either towards or away from the pipe depending on the operation state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual lubrication is used, then device complexity is reduced, but productivity decreases due to operator intervention requirements
Solution Approach 1:
The lubrication system is designed to automatically pump and apply lubricant to the die during threading operations without requiring operator intervention. The pump draws lubricant from the reservoir and delivers it to the die, allowing the system to service itself during operation.
Solution Approach 2:
The lubrication system pre-lubricates the die before threading begins and maintains lubrication throughout the operation. The reservoir is pre-filled with lubricant, and the pump is positioned to deliver lubricant in advance of the die's contact with the pipe.
2Productivity
If onboard lubrication systems are integrated, then productivity improves, but device complexity increases
Solution Approach 1:
The lubrication system is designed as a separate, removable assembly that can be detached from the pipe threader. The pump, reservoir, and associated components form a modular unit that interfaces with the main device but can be removed independently for refilling or maintenance.
Solution Approach 2:
The reservoir is designed to be removable and replaceable, allowing the lubrication system to adapt to different operating conditions and lubricant types. The dynamic configuration allows the system to be reconfigured or maintained without affecting the main pipe threading device.
3Reliability
If the lubrication system is permanently integrated, then reliability improves, but ease of repair worsens
Solution Approach 1:
The lubrication system components (pump, reservoir, hoses) are segmented into separate, removable parts. The reservoir can be detached and refilled independently, and the pump assembly can be removed for maintenance without disassembling the entire pipe threader device.
Solution Approach 2:
The lubrication system is extracted as a separate removable assembly from the main pipe threading device. This allows the lubrication components to be taken out for refilling, cleaning, or replacement without affecting the integrity or operation of the main threading mechanism.
4Stability of the object's composition
If the stand is fixed in one position, then stability improves, but adaptability worsens
Solution Approach 1:
The stand is designed to be adjustable between multiple positions and orientations. The stand can be tilted or rotated to change the angle at which the pipe threader operates, allowing lubricant to be funneled in different directions based on the specific threading task being performed.
Solution Approach 2:
The stand's position and orientation parameters can be changed to optimize lubricant flow patterns. By adjusting the stand angle, the system can control how lubricant flows from the reservoir through the pump and onto the die, adapting to different pipe sizes and threading requirements.
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 lubrication system provides efficient and convenient lubrication during pipe threading operations, reducing friction and heat while allowing for easy removal and transport, and adjustable stand orientations optimize lubricant flow and tool accessibility.
Implementation Method 1
a pump supported upon the reservoir and configured to draw the lubricant from the reservoir
Implementation Method 2
a basin positioned beneath the carriage having an inclined bottom wall for directing lubricant toward the reservoir
