In assembly manufacturing target torques can range from 2Nm to 2000Nm, the higher the torque the greater the risk of injury to the operator as well as an increased chance of impacting the quality and performance of the joint.
Automating these processes has become increasingly important to protect operators, enhance productivity, reduce errors, and ensure the highest level of product quality.
Let’s explores the benefits, challenges, and advancements in automating high torque rundowns, along with the risks posed to humans during manual operations.
High torque rundowns are usually classified as anything over 100Nm and involve applying substantial force to fasten components securely.
Manual high torque fastenings can be prone to inconsistencies and errors, leading to potential failures and costly recalls. Torque Reaction is also a problem and can cause injuries and long term illness to operators who are repeatedly carrying out high torque rundowns.
Automation addresses these issues by providing precise, repeatable, and controlled torque application and with no manual intervention there is no risk of illness or injury to operators.
1. Enhanced Precision and Consistency:
Automated torque systems are designed to apply the exact amount of torque required for each application. This eliminates the variability associated with manual processes and ensures that every fastener is tightened to the specified torque value.
2. Increased Productivity
Automation significantly speeds up the torque application process. Automated systems can perform rundowns faster than human operators, reducing cycle times and increasing throughput. This is particularly beneficial in high-volume production environments where time is a critical factor.
3. Error Reduction
Automated systems incorporate error-proofing mechanisms that detect and correct issues in real-time. This includes torque and angle monitoring, customizable torque sequences, and post-torque inspection. These features help prevent assembly errors that could lead to product failures.
4. Cost Savings
By reducing the need for manual labor and minimizing errors, automation can lead to substantial cost savings. The initial investment in automated torque systems is offset by the long-term benefits of improved efficiency and reduced rework.
1. Physical Strain and Injury
Applying high torque manually can lead to repetitive strain injuries, muscle fatigue, and other musculoskeletal disorders. The physical effort required can be substantial, especially in high-volume production settings.
2. Inconsistencies and Errors
Human operators may struggle to apply consistent torque, leading to variations that can compromise the integrity of the assembly. This inconsistency increases the risk of product failures and safety issues.
3. Safety Hazards
High torque applications can be dangerous, with the potential for tools to slip or components to break under excessive force. These incidents can result in serious injuries to operators.
Recent advancements in torque automation technology have addressed many of these challenges, making it easier for manufacturers to implement and benefit from automated systems:
1. Adaptive Fastening Strategies
Modern torque control systems can adapt to different joint designs and variable tolerances. This flexibility allows manufacturers to handle a wide range of applications with a single system.
2. Real-Time Monitoring and Data Analysis
Advanced torque systems offer real-time monitoring and data analysis capabilities. This enables manufacturers to track performance, identify issues, and make adjustments on the fly.
3. Integration with PLC and Line Control
Automated torque systems can be integrated with programmable logic controllers (PLC) and other line control techniques. This ensures smooth operation and coordination with other automated processes.
Automating high torque rundowns is a transformative step for industries that rely on precise and reliable assembly processes. The benefits of enhanced precision, increased productivity, error reduction, and cost savings make automation an attractive option. While challenges exist, advancements in torque automation technology continue to improve the feasibility and effectiveness of these systems. Additionally, automation significantly reduces the risks posed to human operators, enhancing workplace safety. As manufacturers embrace automation, they can expect to achieve higher quality standards, greater efficiency, and a competitive edge in their respective markets.
