Set-up and Assembly

Floor Diagrams

The machine requires mounting. The diagram shows hole centers for mounting the Shear, Brake, and Roll. The holes are spaced 10 inches (255mm) apart on one axis and 13 inches (330mm) on the other, with four 0.31" (8mm) diameter holes.

Assembly Steps

Tools required: 5mm hex keys, 6mm hex keys, 16mm open-end wrench.

1. Remove the machine and spare parts from the box.
2. 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 they may damage painted surfaces.
3. Coat all machined surfaces with a light film of oil to inhibit rust.
4. Carefully move the machine to a workbench or stand, ensuring free access on all sides.
5. Bolt the machine to the stand or workbench. The stand or workbench must be bolted to the floor. (An optional stand is available; contact your VEVOR distributor.)
6. Remove one handle (A) from each operating handle assembly using a 6mm hex key.
7. Loosen the lock bolt (C).
8. Slide bar (B) into the hub and tighten the 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. Tighten the setting by rotating the hex nut against the cast base of the machine with a 16mm wrench.
11. Install the guide plate as shown in Figures 3 or 4, securing it to the 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) on the bottom die, the full length of the die.
2. Close the brake until the wood contacts the upper dies (E).
3. Loosen screws (D) using a 5mm hex key.
4. Select the desired upper dies (E) and remove the others by sliding them out the left end. (Included die set sizes: 1"x1, 2"x2, 3"x1, 4"x1).
5. Move the operating handle until the wood pushes up the dies, seating them uniformly in the upper beam.
6. Securely re-tighten all screws, then release and remove the wood strip.
7. For 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. Accommodate bend allowance based on material thickness.
9. Rest the workpiece on the v-block (lower die) so the scribed line aligns with the tips of the upper die(s).
10. Hold the workpiece steady and use the operating handle to make the bend.

To adjust brake beam (G) for 90° bends:

1. Slightly loosen locking screws (H) using a 6mm hex key.
2. Turn brake beam adjusting screws (G) with a 16mm wrench until a 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 to account for material "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 shear position (Figure 4) and adjust to the desired length of workpiece cut.
2. Place workpiece against the guide block at the right edge of the table (K, Figure 7).
3. Operate the handle to begin the shearing cut, which progresses from right to left.

Notes:

• To prevent distortion when notching, "snap" the handle to facilitate piercing.
• Do not reach behind the machine to catch cut-off pieces. Allow large pieces to drop onto a dedicated table.
• Large pieces may require a front table for support.
• All cut metal will have a sharp edge. File or sand the edge before handling to avoid injury.

Lower Blade Adjustment

The upper and lower shear blades are factory aligned. If re-alignment is needed:

1. Place a heavy sheet of paper in the cutting position along the entire length of the bed and make a cut.
2. If the shear does not cut the paper cleanly, 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 blades. Do not allow the blades to overlap.
4. If the shear cuts the paper on the ends but not the center, slightly turn screw (N, Figure 9) clockwise until the paper is cut the entire length.
5. If the shear cuts the paper in the center but not the ends, turn screw (N) counterclockwise until the 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 edges become dull:

1. Remove the hold-down by loosening screws (O, Figure 10) with a 10mm hex key.
2. Raise the upper blade to its 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 the hold-down. With the blade in its highest position, the gap between the hold-down and the table should be within 1/4". Adjust using screws (O) as needed. The hold-down should immediately secure the workpiece when the blade starts its downward travel.

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 material is being fed into them. Failure to comply may cause serious injury and/or damage to the machine.

Material Size Considerations

To determine the approximate length of material needed for a desired tube size, use the formula: C = πD, where C is the circumference, π ≈ 3.1417, and D is the diameter. For example, to form a tube with a 4" diameter, multiply 3.1417 by 4" to get the circumference (12.5667"). Cut several pieces to this length for a forming test run, adjusting as needed.

TIP: A slight bend made with the press brake on the leading edge can simplify the initial rolling process by allowing the edge to slip more easily over the idle roll, provided it doesn't interfere with the final shape.

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

1. Ensure rolls and workpiece are clean and free of debris to prevent pitting of sheet metal.
2. Back off the idle roll completely by rotating idle roll screws (Q, Figure 11) counter-clockwise.
3. Loosen bolt (R, Figure 11) to increase the space between the upper and lower press rolls.
4. Insert material between the upper and lower rolls, and tighten bolt (R) to lower the upper roll until the material fits snugly. The upper roll must apply sufficient pressure for proper feeding.
5. Rotate both idle roll screws (Q, Figure 11) to adjust the idle roll's proximity to the two main rollers, raising both ends equally.
6. Run the workpiece through the machine using the handles. Support large workpieces as they exit.
7. Make further passes, raising the idle roll incrementally before each pass, until the desired radius is achieved. Adjustments depend on material "spring back". Test forming several pieces to obtain correct adjustments. It is easier to re-pass material for a smaller radius than to increase a radius that was made too small.

The idle roll must be adjusted parallel to the material to prevent spiraling. Use calipers to measure the opening at each end for greater precision.

Setting the rolls non-parallel can be used to create cone shapes.

To remove cylindrical shaped workpieces:

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

Flat Rolling

Softer metals (copper, aluminum, etc.) can be processed to straighten, flatten, or reduce thickness. Adjust the upper press roll for thickness, lower the idle roll completely, and feed the workpiece through (Figure 13).

Note: The idle roll may not descend completely out of the workpiece path, potentially causing a slight bend. Flipping the workpiece and re-feeding can minimize this bend.

Forming a Radius

1. Adjust the upper press roll as needed.
2. Insert workpiece from the front.
3. Operate the handle. When the material reaches the point where the radius should 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 the 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, with incremental idle roll adjustments.

Forming a Tube

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

Bending Wire

There are 6 wire grooves on the ends of the press rollers: 2.99mm (0.12"), 3.66mm (0.14"), 6.1mm (0.24"), 3.05mm (0.12"), 4.40mm (0.17"), and 5.16mm (0.20"). Use the smallest groove that comfortably fits the wire. Bend the wire using the same principles as forming a radius. For a complete loop, follow the instructions for forming a tube.

Maintenance/Lubrication

Warning: Use caution when performing maintenance work around the shear blades. Use work gloves when handling them.

1. Apply #2 lithium grease to the grease nipples on both ends of the frame (A, Figure 16) once a month.
2. Keep the slip rolls clean and rust-free, and apply a light coat of oil frequently.
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).
