Y-Pipe Vertex Forming for Sharp Angles Without Weld Seams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for constructing Y-pipes either result in sharp vertex angles with potential weaknesses from welding seams or larger vertex angles due to hydroforming, neither of which optimizes fluid flow.
Innovation Solution
A device comprising a first piece with a holder and jaws portion, and a second piece with a wedge and punch portion, controlled by a system to synchronize the movement of the jaws and punch, allowing for the reduction of the vertex angle of a Y-pipe without creating weaknesses or flow disturbances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If welding two parts together is used to construct a Y-pipe, then sharp vertex angles are possible, but welding seams create points of weakness and flow disturbance
Solution Approach 1:
The device divides the Y-pipe construction into two separate parts (first piece and second piece) that are joined together. The first piece forms the main body with holder and jaws portions, while the second piece forms the vertex with wedge and punch portions. This segmentation allows the vertex to be formed separately and joined without creating weak welding seams throughout the entire structure.
Solution Approach 2:
The device acts as an intermediary tool that enables the formation of a sharp vertex without direct welding of the Y-pipe parts themselves. By using the holder, jaws, wedge, and punch components as mediators, the vertex can be shaped precisely and then joined using alternative methods that avoid welding seams.
2Reliability
If hydroforming is used to construct a Y-pipe, then welding seams are eliminated, but the vertex angle becomes much larger
Solution Approach 1:
The device performs preliminary shaping of the vertex before final assembly. The holder and jaws portions are prepared in advance with specific angles, and the wedge and punch portions are configured to achieve the desired sharp vertex angle. This preliminary preparation enables subsequent joining without welding while maintaining the sharp angle geometry.
Solution Approach 2:
The device enables changing the vertex angle parameter to a sharp value that would be impossible with conventional hydroforming. By using the adjustable holder and jaws portions combined with the wedge and punch mechanism, the vertex angle can be precisely controlled to achieve sharp angles while eliminating the need for welding seams.
3Speed
If a small vertex angle is achieved in a Y-pipe, then fluid flow speed increases, but conventional methods create either welding seams or large vertex angles
Solution Approach 1:
The device introduces dynamic elements through the movable jaws portion and the extendable punch portion. The jaws can adjust between different configurations to hold the pipe at various angles, and the punch can extend to different positions to achieve the desired vertex sharpness. This dynamic capability allows optimization of fluid flow speed through precise vertex angle control without compromising structural reliability.
