Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for producing spacers and lattice girders for concrete reinforcements suffer from manufacturing defects during the welding process, such as incomplete or excessive welding, and lack flexibility in producing different types with the same accuracy and speed.
Innovation Solution
A machine with a drive mechanism that continuously securely clamps the spacer using a mechanical gripping system, combined with a welding installation actuated by electrodes, ensures accurate and efficient welding by immobilizing the spacer during welding intervals and transporting it to the next weld point, allowing for precise positioning and reduced defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a welding installation with separate wires and frame structures is used to automatically produce spacers, then production automation is improved, but manufacturing defects increase due to welding inaccuracies
Solution Approach 1:
The spacer is clamped and positioned in advance before the welding operation begins. The drive mechanism secures the spacer at the correct position, and the welding installation is pre-positioned with electrodes ready to weld. This preliminary positioning ensures that when welding occurs, the components are already accurately aligned, reducing welding defects while maintaining automation.
Solution Approach 2:
The patent replaces manual positioning and alignment operations with an automated drive mechanism that uses clamps and mechanical transport to position the spacer. This mechanical substitution eliminates human error in positioning while maintaining automation, thereby improving both automation extent and manufacturing precision simultaneously.
2Productivity
If the welding installation processes spacers at high speed, then productivity is improved, but manufacturing defects increase due to reduced welding quality
Solution Approach 1:
The drive mechanism continuously transports the spacer through the welding installation without interruption. The clamping system maintains continuous contact to hold the spacer steady during welding, while the transport mechanism ensures continuous movement between weld points. This continuity allows high-speed production while maintaining consistent welding quality through stable positioning throughout the entire welding process.
3Adaptability or versatility
If the machine is designed for high flexibility to produce different spacer types, then adaptability is improved, but device complexity increases
Solution Approach 1:
The drive mechanism and welding installation are designed as universal systems that can accommodate different spacer types, sizes, and configurations through programmable control. The clamping system can adjust to various spacer geometries, and the welding installation can be reconfigured for different welding patterns. This universality provides high production flexibility without requiring multiple specialized machines, thereby limiting the increase in device complexity.
