SHEAR BLADE ADJUSTMENTS

The blade was adjusted at the factory. However, after using the shear for a time, it may become necessary to re-adjust the blade.

1. Remove the material hold down by unscrewing the bolts from the hold down bar.

2. Loosen the two table capscrews at each end of the table.

3. Using a flathead screwdriver tighten or loosen the table adjustment screws located under both ends of the table.

Note'': These screws change the distance of the table and fixed blade to the shear blade. The idea is to obtain a snug blade fit without binding the blades.

4. Re-tighten the four table top screws.

5. While keeping fingers clear of the blades, shear a piece of paper along the full edge of the blade.

Adjustment Results

• Shear cuts properly along the full length. Reinstall the hold down and follow the adjustment procedure.

• Shear cuts clean at one end but not the other. Repeat steps 2 & 3 above.

• Shear cuts at both ends of the blade but not at the center. Turn the bow nut (A) clockwise (cw) until the paper cuts clean at all locations.

• Shear cuts at the center but not the blade ends. Turn the bow nut counterclockwise (ccw) until the paper cuts clean the full length.

Once the blade makes a clean cut the whole length, reinstall the hold down and follow the adjustment procedure.

REMOVAL OF BRAKE BLADES FOR CLEANING AND SETUP

Turn the handlebar counterclockwise (ccw) to raise the brake blade die until it contacts the brake blades as shown at right. Using a hex wrench, loosen all of the capscrews holding the gib. Now slide the brake blades out, one at a time. Clean the casting seat, the gib, and all of the brake blades with mineral spirits. After drying, lubricate with an anti-rust lubricant.

Installing the Brake Blades

Turn the handlebar clockwise (cw) to lower the brake blade die. Lay a strip of wood on the brake blade die the full length as shown at right. Start inserting the brake blades. Wide blades to the right and narrow blades to the left when facing the front of the machine. When the brake blades are all in place, turn the handlebar counterclockwise (ccw) to raise the brake blade die. When the brake blades are firmly seated in the casting, tighten all of the capscrews on the gib. Now lower the brake blade die and remove the strip of wood.

LUBRICATION AND MAINTENANCE

Check for the following conditions and repair or replace when necessary:

• Check daily for any unsafe conditions and fix immediately.

• Check that all nuts and bolts are properly tightened.

• On a weekly basis clean the machine and the area around it.

• Lubricate gears, bushings, threaded components and sliding devices.

• Apply rust inhibitive lubricant to all non-painted surfaces.

• Loose mounting bolts.

• Chipped brake fingers.

• Dull or chipped shear blades.

• Inadequate lubrication.

• Any other condition that could hamper the safe operation of this machine.

SLIP ROLL MAINTENANCE

Every (6) months remove and lubricate the roller bushings.

1. With the aid of an assistant carefully remove the top front roll. To do so, back off both top roll adjustment bolts, and rotate the roll release pin (left side of roll), 90°. Be careful not to damage the roll.

2. Remove both bushings from the ends of the roll.

3. With mineral spirits, wipe all old grease from the bushings, gears, roller end shafts, and machined pockets that the bushings rest on.

4. After the parts have dried, lubricate them sufficiently with multi-purpose grease.

5. Apply some 10W30 or equivalent oil into the bushings of the bottom front roll.

6. Lower the idler roll by turning the (2) idler adjustment bolts counterclockwise (ccw). This will give you access to apply oil to the bushings.

7. Remove the idler adjustment bolts and clean the threads. Lubricate with oil and re-install.

BRAKE ALIGNMENT

On occasion, it may become necessary to realign the brake blades and the brake die. Follow the procedure below:

1. The first thing to do is clean and then deburr the brake blades and the V-groove of the brake die.

2. Make sure all brake blades are tight and seated properly.

3. Place a straight piece of .5” to .75” (12.7 to 19mm) diameter tubing (approx.) 42” (1067mm) long in the brake die “V”- groove.

4. Raise the blade die until the side of the pipe lightly contacts the brake blades.

5. From one end to the other, visually check for consistent contact between the pipe and the blades.

6. If you notice a gap at one end of the brake, loosen the (2) carriage lock capscrews at that end, and adjust the jack bolt until the brake blades just touch the pipe.

7. Tighten both capscrews and remove the pipe.

8. After cycling the brake a few times, recheck the alignment.

REPLACING THE SHEAR BLADE

Rotate or Replace Blades

1. Remove the material hold down by unscrewing the bolts (#70) from the hold down bar (#41).

2. Raise the shearing blade assembly to the top of its stroke and secure either by blocking the frame or tying off the handlebar. MAKE SURE it is secure to avoid accidental shearing.

3. Remove the eight flathead screws holding on the upper blade (#40) and remove it from the movable blade (#39). When handling the blade always wear leather gloves to protect your hands.

4. Either rotate the blade or replace it if all the sharp edges have been used. Replace the flat head screws and tighten securely.

5. To rotate or replace the lower blade you must work from the other side (rear) of the machine.

6. Remove the eight flathead screws holding on the lower blade (#40) and remove it from the shear table (#2). When handling the blade always wear leather gloves to protect your hands.

7. Either rotate the blade or replace it if all the sharp edges have been used. Replace the flat head screws and tighten securely.

8. While keeping fingers clear of the blades, shear a piece of paper all along the full length of the blades.

Shear Results

• Shear cuts properly along the full length. Reinstall the hold down and follow the adjustment procedure.

• Shear cuts poorly at the blade ends. Follow the blade adjustment procedure.

• Shear cuts all but one or two locations in the center. Loosen the flat head screw at the location where the cut is poor. Apply a piece of shim material between the blade and the backup and then retighten the screw. Check cut again.

Specifications

With a 16 gauge mild steel capacity for all functions, the SBR-5216 is the most powerful 3-in-1 combination machine on the market. This manual combination shear brake and roll saves space and money for small shops.

  • 52” width lets you roll, bend, and shear 4’ x 8’ sheets.
  • Slip roll portion is on top, press brake in the middle, and sheet metal shear on the bottom.
  • 1.70” minimum rolling diameter.
  • Hardened, adjustable back and top rolls can form different thicknesses.
  • Top roll can swing away from the machine for convenient material removal.
  • 3 grooves on the roll can form wire or round rod.
  • Manual press brake section comes with a fixed bottom V-block die.
  • The SBR-5216 combination shear brake roller bends up to 90°, so you can make perfect corners.
  • 9 movable fingers on the top beam can make many sizes of boxes and pans.
  • Crowning feature adjusts the camber of press brake tooling to make consistent bends across your material.
  • Shear portion includes a spring-loaded clamp or hold-down to keep the material from lifting up, extend blade life, improve cut quality.
  • You can adjust the blade gap to fit different gauges of sheet metal.
  • Includes a material guide.
  • Hardened, reversible blades stay sharp.
  • Manual back gauge helps you easily produce repeatable parts.
