Points of caution and information
Follow the points as described under cutting and slotting (cutting tool,
RS stock no. 541-400)
Bending and box forming
Accessories required
'V' bending tool, RS stock no. 541-422
Corner notching tool, RS stock no. 541-416
A 'V' bending tool for forming up to 90° bends, comprising a 160mm 'V'
groove die and 5 blades 50, 75, 100, 125 and 150mm length. Blades
are not hardened so that they can be cut (with HSS hacksaw) or
machined to required length. Use in conjunction with corner notching
tool RS stock no. 541-416, to form small boxes as described in this
instruction.
Setting procedure
1. Raise the ram to the 'up' position.
2. Set the die down onto the base and retain by the four screws
provided. Do not lock at this point.
3. Fit the appropriate blade to the ram, (Figure 13) ensuring that the
locking screw in the ram holds the blade spigot at the undercut. Do
not lock at this point.
4. Lower the ram slowly and locate the 'V' of the blade into 'V' groove
of the blade.
5. In this position, lock the blade in the ram and the die to the press
base.
6. Raise and lower the blade ensuring that it seats fully and squarely
into the groove.
Bending procedure
7.
For good forming, the length of fold should be no more than 5mm
longer than the blade.
8.
After marking the material with a fold line, place the workpiece flat
on the die face centrally under the blade (Figure 14a).
9.
Lower the blade slowly and align it centrally on the fold line.
10. Pull the handle down firmly in one stroke, to form a bend up to 90°.
11. With the blade pressed fully home, a 90° bend is formed, (Figure
14b), see note.
12. Raise the blade and extract the workpiece clear of the press.
Note: For softer materials an overbend > 90° may be obtained.
Adjustment to 90° may be made using the adjustable stop,
(Figure 1), to limit blade throw.
Box making
Please note the limitations on box size given in Table 1.
13. Preparation will require sheet material cut (Figure 15).
14. For depth of box 'D' cut corner notches as described under corner
notching.
15. The width 'W' and length 'L' of the box will determine blade lengths.
Naturally, for a square box only one blade is needed.
16. For good forming the blade length should be slightly shorter than
the length of the fold, but NOT more than 5mm shorter.
17. With all fold lines clearly marked, (Figure 15), follow items '7' to '11'
for each of the four box sides.
18. To attain the box sizes listed in Table 1 always bend with the main
body of the box away from the press.

the shortest side dimension L or W.

Points of caution and information
19. Use materials up to the max thickness as specified.
20. When cutting blades to required length ensure that the spigot
remains at the centre line of the blade length.
Note: The maximum and minimum blade lengths are 150mm and
19mm respectively.
21. When bending always place the workpiece centrally under the
blade.
22. Protect the tool surfaces and edges from damage by safe storage.
Louvre forming
Accessory required
Louvre tool, RS stock no. 541-393.
A louvre forming tool 44.4mm length by 10mm width to form ventilation
apertures. Minimum spacing between adjacent louvres 5.5mm, (Figure
17b).
Setting procedure
1. Raise the ram to the 'up' position.
2. Set the die down on the press base with the 'D' shape of the louvre
facing either inwards or outwards as required. Figure 16 shows the
'D' facing inwards.
3. Retain the die with four screws provided but do not lock at this point.
4. Fit the punch into the ram and hold with the locking screw in the
undercut of the spigot.
5. Lower the punch, slowly locating it into the die.
6. With the punch set fully into the die, lock the punch in the ram, then
the die to the base.
7. Raise and lower the punch in the die to ensure free movement and
no fouling.
Louvre forming procedure
8. With ram raised, place the workpiece flat on the dieface.
9. Lower the ram, aligning the punch against the workpiece in the
required position. Use a reference line on the workpiece or the end
and back stops as described.
10. Holding the workpiece, pull the handle down firmly in one stroke
until the punch pierces the material and seats fully into the die
(Figure 17a).
11. Raise the ram and re-position the workpiece ready for the next
louvre, (Figure 17b).
12. Spacing between louvres is limited to 5.5mm (min) top to bottom
and side to side.
Points of caution and information
13 Use materials up to the max. thickness as specified.
14. Protect the tool surfaces and edges from damage by safe storage.
Tool rotation plate
Accessories required
Tool rotation plate, RS stock no. 602-195
The plate can be used in conjunction with:
'D' hole punches and dies, RS stock no. 607-415 etc
Cutting tool RS stock no. 541-400
Notching tool, RS stock no. 541-416
'V' bending tool, RS stock no. 541-422
Louvre tool, RS stock no. 541-393
When fitted to the base of the press, the plate allows tool dies to be
rotated through 90°. Using the plate, material may be cut or bent along
two axis lines.
Setting procedure
1. Raise the ram to the 'up' position.
2. Fit the plate to the base of the press using the countersink holes and
the screws provided.
3. Choosing the cutting or bending axis line required, orientate the tool
die on the plate then fix via two of the four 'A' holes, (Figure 18).
4. Complete the setting and punching procedure as described for
individual tools.
