Loosen the bending die cap in a clockwise direction, install the required bending wheel die and tighten the cap.
2. Installation of the clamping die
Loosen the clamping die key bolt, replace the required clamping die and tighten the bolt.
The adjustment method is as follows:
(1) Loosen the clamping die fixing bolt, select the parameter manual mode "bending clamp" until the clamping die reaches the end point (there should be a gap between the bending wheel die and the clamping die).
(2) Tighten the clamping die seat adjustment bolt to fully press the clamping die and the bending die.
(3) Select the parameter manual mode "bending retreat" to retreat the clamping die, and then screw the clamping die seat adjustment screw in about 1/4-1/2 turn.
(4) Tighten the clamping die seat fixing bolt.
3. The adjustment method of the slide plate die is the same as above.
4. Mandrel Cylinder
(1) Screw the mandrel into the mandrel bolt, adjust it to the appropriate position, and then fix the mandrel and nut.
(2) Loosen the mandrel cylinder seat bolt.
(3) Move the mandrel cylinder seat pointer and the guide rail seat scale to the same radius as the pipe bending die.
(4) Tighten the mandrel cylinder seat bolt.
5. Anti-wrinkle device
Install the anti-wrinkle die on the anti-wrinkle plate seat and adjust it appropriately by 1°~2°.
6. Relief valve pressure adjustment
Do not release any manual state of clamping, unclamping, core feeding, and core withdrawal. The pressure displayed on the pressure gauge is the relief valve pressure. At this time, rotate the relief valve pressure adjustment handle to adjust the pressure to the required pressure of about 10MPa, depending on the bending resistance of the pipe. It should not be too high to avoid excessive oil temperature and accelerated wear of hydraulic parts.
