Twist correction machine

Twist correction machine

A correction device for rail materials up to approximately 40mm square, targeting twisting (warping) distortion!

We handle a "Twist Correction Machine" that clamps one side of the rail material from above and below, measures the balance between the bottom surface of the clamp and the bottom surface on the opposite side, and twists it in the opposite direction if it is out of specification. Pass/fail standard values and correction amounts can be set arbitrarily. There is also a setting to change the correction ratio (the percentage of correction) without altering the correction value, allowing for easy adjustments based on variations in hardness for each production lot or the amount to revert in case of excessive twisting. 【Equipment Configuration】 ■ Twist Correction Machine Line 　・Twist Correction Machine Main Unit 　・Hydraulic Unit 　・Electrical Control Panel 　・Operation Panel *For more details, please download the PDF or feel free to contact us.

End bending correction machine

End bending correction machine

It corrects bending distortion up to about 500mm from one end face of rail material with a thickness of approximately 40mm.

We handle the "End Bend Correction Machine." There are vertical specifications for one-direction correction and horizontal specifications that correct by pushing and pulling. Both types operate by inserting the item fully and then, while extruding at a specified pitch, they measure and correct at each point. Additionally, the horizontal specification allows for setting the number of correction points and the pitch for extraction, enabling the measurement of the target area as a whole and identifying the correction points. We can also create end bend correction lines that combine 90-degree rotation and insertion conveyors. 【Equipment Configuration】 ■ End Bend Correction Machine Main Unit ■ Conveying Conveyor ■ Loading Device ■ Separate Control Panel ■ Hydraulic Unit ■ Separate Operation Panel ■ Hand Switch BOX *For more details, please download the PDF or feel free to contact us.

Warped Roll Correction Machine

Warped Roll Correction Machine

Leave the automation of distortion correction work that cannot be done with a press correction machine and leveling to us!

<Distortion Correction Roll Machine> Corrects complex distortions across the entire workpiece! Reduces processing distortions! • This roll correction machine, arranged in a staggered pattern with multiple rolls, performs bending correction of peaks and valleys across the entire workpiece, unlike point-specific corrections in press correction. • By bending the workpiece once, it can also equalize the complex internal stresses inherent in the workpiece, thereby reducing processing distortions that occur during machining and bending processes.
