USING THE MACHINE
To perfectly identify the components detailed in the description of operating uses, users must consult the graphic tables enclosed with this
manual.
- BAR BENDING AND PIERCING CYLINDER
(see Figs. 5a / 5b / 5c)
To bend copper bars (max. angle of bend 90°) follow the sequence of operations listed here:
1.
Connect the female coupling located at the end of the supply pump pipe to that on the machine cylinder (detail G).
2.
(only for 009012-B) Insert the electrohydraulic control box connector into the inlet on the front panel of the BBP (detail A).
3.
(only for 009012-B) Insert the connector of the goniometer (detail B) into the appropriate socket on the work surface (detail C).
4.
Raise the protective guard (detail E).
5.
Position the copper bar to be bent (resting it on its side on the work surface) between the elements of the bending tool already fitted as
standard (details L and M/N).
6.
Position the bar with respect to the centre of the bend using the graduated bar stop (detail F); slacken the handle to move the bar stop
plate.
7.
Turn the handwheel (detail H) at the front of the machine to raise or lower the bar bending block so that the tool pushes on the centre
of the bar to be bent (rotate clockwise to lower the block and anticlockwise to raise it). Use the millimetric rod (detail T) for measuring
the movements.
8.
Set the required angle of bend by turning the handwheel (detail D). To carry out the operation slacken it and position it manually so
that the front part of the dropper is set at the preselected angle. Finally, lock the handwheel.
9.
Lower the protective guard.
10. Operate the supply pump pedal to provide the consent to the bending operation.
11. Once the angle of bend has been achieved discharge the pump to ensure that the cylinder returns to its starting position (see pump
instructions booklet).
(only for 009012-B) When the microswitch positioned on the tab comes into contact with the dropper it will stop the control box and
will cause the cylinder to return automatically.
All that remains to be done is for the protective guard to be raised and the bent copper bar to be extracted.
Note: depending on the type of material and their size metal bars may have a tendency to spring back. Therefore once the first bend has been
completed, it will be necessary to check the accuracy of the bend obtained and where necessary carry out any adjustments in order to achieve a
consistent repetitiveness of the bend.
To pierce a copper bar, on the other hand, follow the sequence of operations listed here:
1.
Check that the female coupling located at the end of the supply pump pipe is connected to the one mounted on the machine cylinder
(detail G).
2.
(only for 009012-B) Check that the electrohydraulic control box connector is inserted in the inlet on the front panel of the BBP (detail
A).
3.
Raise the protective guard (detail E) and remove the contrasting pin (detail N or M) vertically and the bending tool (detail L)
horizontally.
4.
Insert the female die (detail U) of the tool designed for the piercing operation. Where a slotted hole is required, the nut (detail S) will
need to be tightened once the die has been inserted in order to create a guide and to prevent the die from rotating. To prevent the
female from becoming jammed in its housing it is important not to over-tighten the guide nut. When inserting round punches however
ensure that the guide nut has been slackened.
5.
Position the male punch (detail P) in its housing and lock the same punch in place using the blocking nut (detail V). In the case of
slotted punches attention must be paid to the position of the coupling between the male punch and female die. Mounting the slotted
punch is simple. The punch needs to be inserted so that the pin fits into one of the two reference holes in accordance with the direction
required.
6.
Position the copper bar to be pierced between the elements of the tool that has just been installed, resting it on its side on the work
surface.
7.
Turn the handwheel (detail H) located on the front of the tool (turning it clockwise will lower the block whilst turning anticlockwise
raises it). Doing this will determine the position of the centre of the hole with respect to the surface. The millimetric rod (detail T)
located on the side of the block indicates the value of the centre to centre distance of the hole in relation to the side of the bar resting
on the work surface.
8.
The bar stop (detail F) is used to establish the horizontal position of the hole to be created in relation to the edge of the bar.
9.
Lower the protective guard.
10. Operate the supply pump pedal to provide the consent to the piercing operation.
11. Once the hole has been created discharge the pump to ensure that the cylinder returns to its starting position (see pump instructions
booklet).
(only for 009012-B) A sensor will stop the control box and will cause the automatic return of the cylinder.
All that remains to be done is for the protective guard to be raised and the pierced copper bar to be extracted.
WARNING
During bending or piercing the automatic stopping devices will only function with the 00HP1550 electrohydraulic control box.
With 00PA2002 and 00PA2004 pumps it is necessary to pay attention to the visual references: goniometer tab for the bending
operation, coloured recess located on the cylinder stem for the piercing operation.
