How to Change the Feeding Direction of a Cold Saw in ERW Tube Mill

In some cases, customers may need to change the feeding direction of the ERW tube mill production line due to workshop layout adjustments or relocation to a new factory.

The cold saw unit is one of the key sections that requires modification when reversing the production line direction.

As a professional ERW tube mill manufacturer, HEBEI AIS MACHINERY provides the following general guidance for adjusting the feeding direction of a cold cutting saw.


Step 1: Exchange the Infeed and Outfeed Roller Tables

First, interchange the infeed roller table and the outfeed roller table on both sides of the cold saw.

This ensures the steel pipe enters and exits the cold saw correctly after the production direction is reversed.


Step 2: Adjust the Clamping Unit Position

The clamping device of the cold saw must be repositioned according to the new feeding direction.

Proper alignment of the clamping system is essential to maintain cutting accuracy and production stability.


Step 3: Reconnect the Encoder Wiring

After mechanical adjustments, the encoder wiring must be reconnected accordingly.

Correct encoder signal direction is critical to ensure accurate pipe length measurement and synchronized flying cutting operation.


Step 4: Modify Servo Drive Parameters

Finally, update the servo drive parameters in the control system.

Parameter modification ensures correct motion direction, speed synchronization, and cutting accuracy under the new feeding configuration.


Important Notice

Please note that different cold saw designs may vary in structure and control logic.

The above steps are provided for general reference only.

For detailed technical guidance, it is strongly recommended to consult professional engineers.

HEBEI AIS MACHINERY provides full technical support for ERW tube mills, cold saw units, and complete pipe production line solutions.
