Solution Overview
Problem
Existing methods for producing ring-shaped or tubular parts from thin steel strips are inefficient due to the need for multiple complex work steps, high mechanical and electronic effort, and increased costs associated with tool changes and investment, especially when producing different pipe diameters.
Innovation Solution
A method that integrates cutting, rounding, and welding into a continuous process using a combination machine, allowing thin-walled sheet metal to be cut, formed, and welded in a single system without requiring tool changes, reducing investment and operational costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple separate machines are used for cutting, rounding, and welding, then each process can be performed with specialized equipment, but the overall system complexity increases and requires multiple tool changes for different pipe diameters
Solution Approach 1:
The patent combines cutting, rounding, and welding operations into a single integrated machine platform. The cutting device, rounding device, and welding device are all mounted on the same machine base, allowing them to operate sequentially on the same workpiece without requiring transfer between separate machines or tool changes.
Solution Approach 2:
The machine is designed with universal functionality to perform multiple operations (cutting, rounding, welding) on various pipe diameters using the same equipment. The rounding device can adapt to different diameters without requiring tool changes, and the welding device can accommodate different workpiece sizes on the same platform.
2Manufacturing precision
If complex forming tools and multiple bending steps are used to achieve dimensional accuracy, then the desired shape can be obtained, but the production time increases and automation becomes difficult
Solution Approach 1:
The workpiece is clamped in a fixed position before processing begins. The cutting device creates precise initial cuts, and the rounding device then forms the tubular shape in a continuous motion without requiring multiple intermediate bending steps or adjustments, achieving both precision and efficiency.
Solution Approach 2:
The rounding process is performed as a continuous operation without interruption. The workpiece remains clamped and is formed into the tubular shape in one continuous motion, eliminating the need for multiple discrete bending steps and intermediate positioning operations that would increase production time.
3Adaptability or versatility
If tool changes are made for different pipe diameters, then the correct forming tools are used for each size, but the machine time increases and cost-effectiveness decreases
Solution Approach 1:
The rounding device is designed with universal adaptability to handle different pipe diameters using the same tooling. The device can adjust its forming action to accommodate various sizes without requiring physical tool changes, maintaining both versatility and operational efficiency.
4Ease of manufacture
If separate loading systems and multiple machines are used, then each process step can be optimized independently, but the overall investment costs increase
Solution Approach 1:
The patent integrates cutting, rounding, and welding functions into a single machine system that processes the workpiece sequentially in one clamping operation. This consolidation eliminates the need for separate loading systems and multiple independent machines, reducing overall system complexity while maintaining process optimization capabilities.
