Assembly
Tools required for setup and assembly, 6mm hex keys (“Allen wrenches”) and 16mm open-end wrench.

1. Take out the machine and spare parts from the box.
2. Carefully clean all rust-protected surfaces with a mild solvent or kerosene and a soft rag. Do not use lacquer thinner, paint thinner, or gasoline, as these may damage painted surfaces.
3. Coat all machined surfaces with a very light film of oil to inhibit rust.
4. Carefully move the machine to a workbench or stand. Machine location must allow free access on all sides.
5. Bolt machine to stand or workbench. The stand or workbench must be bolted to the floor.
   • ( NOTE: An optional stand is available for this machine; see Section 8. Contact KAKA distributor to order.)
6. Remove one handle (A, Figure 2) from each operating handle assembly, using a 6mm hex key.
7. Loosen lock bolt (C, Figure 2).
8. Slide bar (B) into the hub and tighten lock bolt (C) to secure.
9. Re-install handle (A).
10. Install both guide rods into either the upper or lower set of threaded holes(Figures 3 & 4) and tighten the setting by rotating the hex nut against the cast base of the machine with a 16mm wrench.
11. Install guide plate as shown in Figures 3 or 4. Secure it to rods using the T-handles.
    • NOTE: For brake operation, install guide rods into the upper set of holes(Figure 3); for shear operation, install them in the lower set of holes (Figure 4).

PRESS BRAKE SET-UP

WARNING: Do not bend material larger than 12” 20-gauge mild steel. Failure to comply may cause serious injury and/or damage to the machine.

To set up for bending:

1. Place a strip of wood (F, Figure 5) on the bottom die, the full length of the die.
2. Close the brake until the wood contact supper dies(E).
3. Loosen screws (D) using a 5mm hex key.
4. Select upper dies (E) for the desired job and remove the others by sliding them out the left end.（Included die set sizes1”x1, 2”x2, 3”x1, 4”x1）
5. Move the operating handle until the wood pushes up the dies so that they sit uniformly in the upper beam.
6. Securely re-tighten all screws (Figure 3), then release and remove the wood strip.
7. If making repeated bends or using along the workpiece, position guide rods and plate for brake operation, as shown in Figure 3.
8. Scribe a line on the workpiece for the bend location. (Be sure to accommodate bend allowance based on the thickness of the material. This can be done either through trial and error or by consulting a machinist’s handbook.)
9. Rest the workpiece on the v-block (lower die)so that the scribed line is aligned with the tips of the upper die(s).
10. Hold the workpiece steady and use the operating handle to make the bend.

To adjust the brake beam (G, Figure 6) for90° bends at the bottom of the stroke:

1. Slightly loosen locking screws (H)using a 6mm hex key.
2. Turn the brake beam adjusting screws (G)with a 16mm wrench, until the test bend reflects a 90° bend at both ends of the brake.
3. Re-tighten screws (H).
   • For special repetitive bends, the brake beam may be adjusted to over-bend the desired angle since the metal will have some degree of “spring back”.

Shear set-up

WARNING: Do not shear material larger than 12” 20 gauge mild steel. Failure to comply may cause serious injury and/or damage to the machine.

1. Install guide rods and plate in the shear position (Figure 4) and adjust to the desired length of the workpiece cut.
2. Place the workpiece against the guide block at the right edge of the table (K, Figure 7). The end of the workpiece should be against the guide plate.
3. Operate the handle to begin the shearing cut. Shearing action progresses from right to left.

NOTE: 1

1. To prevent distortion when notching, “snap” the handle to facilitate piercing.
2. Do not reach behind the machine to catch the cut-off piece. A large cut-off piece should be allowed to drop onto a special table designed to catch pieces that are bigger than the workbench.
3. Large pieces being cut may require a front table to support the piece.
4. All metal cut on this machine will have a sharp edge. File or sand the sharp edge before handling to avoid injury.

Lower Blade Adjustment
Upper and lower shear blades have been factory-aligned and should not require immediate adjustment. Should re-alignment be needed in the future, proceed as follows:

1. Place a heavy sheet of paper in the cutting position, along the entire length of the bed, and cut.
2. If the shear does not cut the paper, loosen screw (L, Figure 7) at each end of the table, with a 6mm hex key.
3. Rotate adjustment screws (M, Figure 8)to shift the table and change the gap between the blades. Do not allow the blades to overlap.
4. If the shear cuts the paper on the ends, but not the centre, slightly turn the screw (N, Figure 9) clockwise until the paper is cut the entire length.
5. If the shear cuts the paper in the centre, but not the ends, turn screw (N)counterclockwise until paper is cut the entire length.

Blade Rotation/Replacement

WARNING: Exercise caution when working with or near the blades. Use work gloves when handling them.

The shearing blades are reversible and interchangeable; when the edges dull, rotate them to the new edge, as follows:

1. Remove the hold-down by loosening screws (O, Figure 10), using a 10mm hex key.
2. Raise the upper blade to the highest position.
3. Remove 4 screws (P, Figure 10) and carefully remove the blade.
4. Rotate or replace the blade and re-install screws (P).
5. Re-install hold-down. When the blade is in the highest position, the gap between the hold-down and the table should be within 1/4. Adjust to this position by turning the wo screws (O, Figure 10) as needed. When the blade starts its downward travel, the hold-down should immediately hold the workpiece in place.

Slip Roll set-up

WARNING: Do not roll material larger than 12” 20-gauge mild steel. The slip roll guard must cover the rolls except when the material is being fed into the rolls. Failure to comply may cause serious injury and/or damage to the machine.

Material Size considers rations

• To determine the approximate length of material needed for a desired size tube, use the following formula :

C =πD

• Where C is the circumference, π equals3.1417 and D is the diameter.
• For example: To find the length of material needed (C) to form a tube 4″ in diameter, multiply 3.1417 by 4″. Result:12.5667″ is the circumference of the approximate length of material needed. Cut several pieces of material to this length for a forming test run. Material may have to be lengthened or shortened depending on the results of the test run.
• TIP: If it doesn’t interfere with the proposed final shape or design, a slight bend made with the press brake on the leading edge will simplify the initial rolling process, by allowing the leading edge to slip more easily over the idle roll.

WARNING: Beware of pinch point –the intersection of upper and lower rolls. Failure to comply may cause serious injury to fingers and/or hands.

1. Make sure rolls and workpieces are clean and free of debris to prevent the pitting of sheet metal.
2. Back off the idle roll completely by rotating the idle roll screws (Q, Figure 11)counter-clockwise.
3. Loosen bolt (R, Figure 11) to increase space between upper and lower press rolls.
4. Insert material between upper and lower rolls, and tighten the bolt (R, Figure 11)to lower the upper roll, until the material fits snugly. The upper roll must have sufficient pressure on the workpiece to feed properly.
5. Rotate both idle roll screws (Q, Figure11) to adjust the idle roll’s proximity to the two main rollers. Raise both ends an equal amount.
6. Run the workpiece through the machine using the handles. If the workpiece is large, make sure it receives proper support as it exits the machine.
7. Make further passes of the workpiece, raising the idle roll incrementally before each pass, until desired radius is achieved. No exact formula can be followed when making roll adjustments because material “spring-back” varies with the kind of material being formed. Only by test forming several pieces can correct adjustments be obtained. Also, keep in mind that it is much easier to re-pass material to make a smaller radius than to attempt to increase a radius that was made too small.

The idle roll must be adjusted exactly parallel or the material will spiral during the rolling process. Measure each end of the opening with callipers if greater precision is required. Deliberately setting the rolls non-parallel can be used to make cone shapes.

To remove cylindrical-shaped workpieces:

1. Loosen bolt (R, Figure 12)
2. Carefully grasp the upper roll and swing out the end. Grasp the upper roll firmly, to prevent it from falling out of a machine.
3. Slip the workpiece off the end of the roll.
4. Re-install the upper roll, and tighten the bolt (R, Figure 12).

Flat Rolling

Softer metals (copper, aluminium, etc.)can be processed through the slip-roll machine to straighten, flatten, or reduce their thickness. Simply adjust the upper press roll for thickness, lower idle roll down, and feed the workpiece through (Figure 13).
NOTE: The idle roll will not descend completely out of the path of the workpiece; thus, there may be a slight bend in the workpiece. By flipping the workpiece over and re-feeding it, this bend can be minimized.

Forming a Radius

1. Adjust the upper press roll as needed.
2. Insert the workpiece from the front.
3. Operate handle; when the material reaches the point where the radius is to begin (a, Figure 14), stop the machine and raise the idle roll an equal amount on each end to achieve the desired bend.
4. Restart rolls and continue until the bend is completed (b, Figure 14). Support the workpiece as it exits the machine.
5. Make further passes if needed, along with incremental idle roll adjustments.

Forming a Tube

1. Adjust the upper press roll as needed for workpiece thickness.
2. Feed workpiece into machine. As it nears the end (a, Figure 15), stop and reverse direction (b, Figure 15).
3. Make further passes if needed, along with incremental idle roll adjustments.

Bending Wire

• There are 6 wire grooves at the ends of the press rollers to accommodate a2.99mm(0.12”), 3.66mm(0.14”), 6.1mm(0.24”), 3.05mm(0.12”), 4.40mm(0.17”), 5.16mm(0.20”)wire.
• Use the smallest groove into which the wire will comfortably fit. Bend the wire using the same principles as described for forming a radius.
• To make a complete loop of wire, use the instructions for forming a tube.

Maintenance/Lubrication

WARNING: Use caution when doing maintenance work around the shear blades.

1. Apply #2 lithium tube grease once a month to the grease nipples on both ends of the frame (A, Figure 16).
2. Keep the slip rolls clean and rust-free, and frequently apply a light coat of oil to them.
3. Lightly brush multi-purpose grease onto the gears at the end of the rollers (B, Figure 16). Turn the operating handle to distribute the grease.
4. Keep other exposed areas clean and lightly coated with oil, such as the shear blades, table and upper dies. (Remove upper dies from the bar for more effective cleaning).
