DW89NC Hydraulic Pipe Bending Machine With 220v / 380v / 110v
-- Installation points
After the system is set up, you can work. When you work manually,
select the switch to select the manual position and press the
manual button step by step. When working automatically, select the
switch to select the automatic position, press the start button or
step on the toe switch, and immediately release it.
The automatic operation starts. If you press the start button again
or step on the foot switch, the work is suspended. After you press
the stop work button, the manual work and automatic work are all
-- Operating system instruction
1. Bending die installation
Plunge the elbow in a clockwise direction and cap it. Replace the
required elbow wheel die and tighten the cap.
2. Clamp mold installation
Insert the clamping die with adjusting bolts, adjusting plates and
cover plates into the clamping die holder and connect the adjusting
bolts. The clamping die of the adjusting plate, cover plate, etc.
is inserted into the clamping die holder and the adjusting plate is
inserted. Fix on the clamp mold base and rotate the adjusting bolt
so that the center of the clamp mold and the center of the bend
tube mold are on the same plane.
3. Skateboard die adjustment method ditto
4. Mandrel and cylinder installation
5. Anti-crease device
The wrinkle-resistance mold is mounted on the wrinkle-proof plate
seat, and it can be properly adjusted as shown in the figure by 1°
6. Bending angle adjustment
The bend angle control is controlled by a proximity switch, a scale
display is shown at the adjustment position of the proximity
switch, and the proximity switch adjustment block is adjusted to a
desired angle. Above is the first angle, below is the second angle,
corresponding to the angle/double angle selection on the operation
panel, after the trial bend and then trim the angle. Because the
material of the pipe is different, the rebound amount is also
different. After the adjustment is completed, the locking screw
lock nut on the nut will be adjusted.
7. Overflow valve pressure adjustment
Press any of the manual buttons of pinch tube, back clamp, core,
and back core to release the pressure displayed on the pressure
gauge. At this time, rotate the pressure relief handle of the
overflow valve to adjust the pressure to the desired pressure of 10
MPA. The bending resistance should not be too high, so as not to
increase the oil temperature and to accelerate the wear of
-- Brief introduction
NC pipe bending machine is mainly used for electric power
construction, public railway construction, boiler laying, bridges,
ships, furniture, decoration and other aspects of pipe laying and
repair, which has many functions, reasonable structure, simple
operation, easy movement, quick installation and so on. This series
pipe bending equipment has the advantages of low price and
convenient use, and it occupies the leading position in the
domestic bending machine market. It can bend the pipe under cold
state (single mode) or two bend radius (double modes). It is widely
used in the bending of various pipes and wires in the automotive
and air conditioning industries. In the process of pipe bending,
the outer diameter and thickness of different pipes and the
different bending radius directly lead to the different bending
moment of the pipe. Therefore, the design of the pipe bending
machine needs to calculate and determine the bending moment of the
pipe first. The size of the pipe is directly related to the power
of the motor and the type selection of the transmission mechanism.
