Adjustable Pipe Stop for Precise Butt Welding Protrusion Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe welding technologies fail to allow individual adjustment of pipe protrusions, leading to unnecessary material waste and inefficiency due to uniform removal of protrusions regardless of the specific requirements of the fittings.
Innovation Solution
A pipe stop with two adjustable stop discs and locking elements, allowing independent adjustment of pipe protrusions, which can be easily positioned and secured on a welding machine, enabling precise and efficient cutting of pipes to the desired length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a rigid block is inserted between pipe ends to define axial position, then pipe protrusion length is standardized, but individual adjustment of pipe protrusion is impossible leading to material waste
Solution Approach 1:
The rigid block is segmented into a holder and two stop discs that can be independently adjusted. This segmentation allows each stop disc to be positioned separately to define precise pipe protrusion lengths for different pipes, eliminating the need to remove excessive material and reducing waste.
Solution Approach 2:
The stop discs are made adjustable along the axial direction of the holder, transforming the static rigid block into a dynamic system. The stop discs can be moved to different positions using adjusting elements, enabling individual customization of pipe protrusion lengths while maintaining manufacturing precision.
2Device complexity
If a rigid block is used to define pipe protrusion, then positioning is simple, but multiple clamping operations are required removing time
Solution Approach 1:
The positioning mechanism is segmented into adjustable stop discs that can be set once for multiple pipes. This allows different pipe protrusion lengths to be defined without requiring multiple clamping operations, reducing time loss while maintaining simple positioning.
Solution Approach 2:
The stop discs are adjusted in advance to the required positions before pipe clamping. This preliminary action enables all necessary pipe protrusion definitions to be prepared beforehand, eliminating the need for repeated clamping and adjustment operations during the welding process.
3Adaptability or versatility
If stop discs are made axially adjustable, then individual pipe protrusion adjustment is enabled, but device complexity increases
Solution Approach 1:
The stop discs are designed with adjusting elements that enable axial movement along the holder. This dynamic capability provides adaptability for individual pipe protrusion adjustment while keeping the adjusting mechanism relatively simple through the use of threaded connections and locking elements.
Solution Approach 2:
The position of the stop discs along the axial direction is made variable through adjusting elements. By changing the axial position parameter of each stop disc independently, the system achieves high adaptability for different pipe protrusion requirements without requiring complex adjustment mechanisms.
