Grizzly Industrial T1241 20 Ton Hydraulic Press Instructions

Grizzly Industrial T1241 20 Ton Hydraulic Press

Eye injury hazard! Always wear safety glasses when using this machine. Crushing hazard! Always keep hands clear when using this machine.

Identification

• Hydraulic Ram. Applies pressure directly to workpiece. Hydraulic ram operates using pressure for downward ram movement.
•  Pressure Gauge. Shows pounds of force (in tons) per inch being applied to workpiece.
•  Table Plates. Support workpiece during pressing operation.
•  Pump Handle. Generates hydraulic pressure in ram when pumped up and down. Moves ram downward.
•  Tank Relief Valve. Releases pressure from hydraulic ram to release workpiece.
•  Hydraulic Fluid Reservoir. Holds hydraulic fluid for operation of hydraulic ram.
•  Micro Pump Valve. Increases hydraulic ram pressure in small increments.
•  Standard Pump Valve. Increases hydraulic ram pressure in large increments.
•  Bed Adjustment Holes. Holds support rods to position press bed at desired height.
•  Support Rods. Support press bed using holes in machine frame.
•  Press Bed. Platform for table plates supports workpiece during pressing operation.

Always ensure workpiece is positioned so force is evenly distributed. Off- center workpieces can be ejected unexpectedly from force of hydraulic ram, striking operator or bystanders and causing injury.

Assembly

1.  Lay columns on the ground and connect base supports and center brace, as shown in Figure 3, using (4) M12-1.75 x 30 hex bolts, 12mm flat washers, 12mm lock washers, and M12-1.75 hex nuts.

2. Attach (2) angle braces to each base support using (8) M10-1.5 x 25 hex bolts, 10mm flat washers, 10mm lock washers, and M10-1.5 hex nuts, as shown in Figure 3.

3.  With help from an assistand, secure cross beams to top of columns (see Figure 4) with(8) M16-2 x 35 hex bolts, 16mm flat washers, 16mm lock washers, and M16-2 hex nuts. When installing second cross beam, position ram mounting plate over bottom edges of cross beams, as shown in Step 4.

4. Secure ram mounting plate in center of cross beams using (4) M8-1.25 x 16 hex bolts through pre-drilled holes in mounting holes (see Figure 5).

5. From above, insert hydraulic ram cylinder through hole in ram mounting plate and thread ram collar into position, as shown in Figure 6.
   Note: Ram collar can be tightened by insert-ing a Phillips head screwdriver into collar holes and lightly tapping across shaft of screwdriver with a mallet to rotate until tight.

6. Attach hydraulic reservoir assembly to right side of press column (see Figure 7) with (2) M10-1.5 x 25 hex bolts, 10mm flat washers, and 10mm lock washers, and M10-1.5 hex nuts.

7.  Connect hydraulic line to top end of hydrau-lic ram cylinder and hydraulic tank (see Figure 8).

8.  Attach pressure gauge to the top of hydraulic ram (see Figure 8).Use thread tape on pressure gauge threads to ensure a proper seal during opera-tion.

9.  Assemble bed with (4) sleeve spacers between bed sides and secure together with(4) M10-1.5 x 130 hex bolts, 10mm lock washers, 10mm flat washers, and M10-1.5 hex nuts, as shown in Figure 9.

10.  Place table plates on press bed, and insert pump handle into left or right receiver on top of hydraulic tank (see Figure 10).Note: Left receiver is used for smaller incre-mental ram movement, and right receiver is used for larger incremental ram movement.

Anchoring to Floor

Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs slightly quieter and feels more solid.If the machine will be installed in a commercial or workplace setting, local codes may require that it be anchored to the floor.If not required by any local codes, fastening the machine to the floor is an optional step. If you choose not to do this with your machine, we rec-ommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads.

Anchoring to Concrete Floors
Lag shield anchors with lag screws (see below) are a popular way to anchor machinery to a con-crete floor, because the anchors sit flush with the floor surface, making it easy to unbolt and move the machine later, if needed. However, anytime local codes apply, you MUST follow the anchoring methodology specified by the code.

Operating Press

1. Fully rotate tank relief valve (see Figure 12) clockwise to close it.
2. Raise press bed to desired height, insert sup- port rods, as shown in Figure 13, into holes in machine frame, then lower bed onto sup-port rods.
3. ALWAYS make sure support rods are sup-porting bed evenly! Failure to support press bed evenly could lead to bed accidentally dropping during setup or operation, which may result in crushing injury. Place table plates on press bed (see Figure 14), and place workpiece onto blocks.
4. Pump handle to lower ram or increase down- ward pressure. Refer to pressure gauge for actual workpiece pressure (see Figure 15). Ram should lower smoothly.
5. Rotate tank relief valve (see Figure 16) coun-Rotate tank relief valve (see Figure 16)

Maintenance

The T1241 20-Ton Press features a fully-sealed hydraulic unit. Periodically check press for loose mounting bolts or any unsafe conditions. Thoroughly clean press components on an as-needed basis for best operation.
To clean/maintain press:

1.  Wipe all dirt and dust off press components.
2.  Apply light oil to surface of ram.
3.  Check hydraulic ram and press bed sup-port rods for cracks or damage. Replace if necessary.
