TruAxis™ Straightening System

Bars and tubes produced for precision applications today are often not completely straight. This poses a problem for manufacturers who rely on machining or centerless grinding operations to finish these bars or tubes. To combat this problem, Lincoln Electric Automation has developed a fully automated bar/tube straightening system that automatically adapts to variances in the tubes without requiring operator intervention. The TruAxis™ Straightening System is capable of handling a wide variety of lengths and diameters. As compared to other methodologies, these systems have helped to reduce cycle times by up to 60-80% while achieving straightness over the entire bar/tube within 0.02" tolerance.

Features

• Automated X-Axis – The C-Frame press traverses via servo motion across multiple data points to determine the pre- and post- bent state or straightness of the stock.
• Measuring Supports – Cam roller guides support the bar/tube/piece during rotation & measurements.
• LVDT Measurement – Linear Variable Differential Transformer (LVDT) measures the straightness of the bar/tube/piece as it rotates.
• Servo Press – A servo press moving on a servo-driven axis applies bending force to bar/tube/piece. (40 US Ton – 356kN or 50 US Ton – 445kN)
• Infeed Queue – Stock support and feed table queue parts ahead of straightening. Queue configuration design is scalable and can accommodate manual or automatic loading configurations.
• Standard control systems includes 24VDC Allen Bradley® control, Rockwell® servo motors and a 15” HMI screen with manual & automatic modes. System can be configured to accommodate other control platforms.
