6.0 Set-Up and Assembly 6.
6.2 Unpacking Open shipping container and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Shear/Brake/Roll machine is assembled and running properly. Compare the contents of your container with the following parts list to make sure all parts are intact. Missing parts, if any, should be reported to your distributor. Read the instruction manual thoroughly for assembly, maintenance and safety instructions.
NOTE: For brake operation, install guide rods into upper set of holes (Figure 4); for shear operation, install in lower set of holes (Figure 5). To adjust brake beam (G, Figure 7) for 90° bends at bottom of stroke: 12. Install guide plate as shown in Figures 4 or 5. Secure it to rods using the T-handles. 1. Slightly loosen locking screws (H) using 8mm hex key. 2. Turn brake beam adjusting screws (J) with 19mm wrench, until test bends reflect 90° bend at both ends of brake. 3. Re-tighten screws (H).
Figure 10 6.5.2 Blade Rotation/Replacement Figure 8 6.5.1 Lower Blade Adjustment Exercise caution when working with or near the blades. Use work gloves when handling them. 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. 2. 3.
4. Insert material between upper and lower rolls, and tighten bolt (R, Figure 12) to lower the upper roll, until material fits snugly. The upper roll must have sufficient pressure on work piece to feed properly. 5. Rotate both idle roll screws (Q, Figure 12) to adjust idle roll’s proximity to the two main rollers. Raise both ends an equal amount. 6.
5. 3. Reinstall upper roll, and tighten screw and bolt (S, Figure 13). Make further passes if needed, along with incremental idle roll adjustments. 6.6.1 Flat Rolling Softer metals (copper, aluminum, 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 all the way down, and feed workpiece through (Figure 14). Figure 16 6.6.
7.0 Maintenance/Lubrication 8.0 Optional Accessories 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 frame (A, Figure 17). 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 17). Turn operating handle to distribute the grease. 4.
9.0 Troubleshooting Trouble Probable Cause Remedy Incorrect blade gap. Adjust gap to accommodate thicker material. Machine capacity exceeded. Use materials within capacity. Unequal blade gap. Make blade gap equal. Not contacting table guides. Maintain consistent guides contact. Blade is bowed. Remove bow. Insufficient hold-down pressure. Adjust hold down. Dull blade(s). Replace or sharpen. Incorrect blade gap. Adjust gap as needed. Loose gibs. Adjust backlash out of gibs.
