SAFEGUARDING THE POINT OF OPERATION

ANSI B11.2 – Hydraulic Power Presses – Safety Requirements for Construction, Care, and Use It is important that Dake press users have a clear understanding of their responsibility involving the care and use of their Dake hydraulic press, including point-of-operation safe guards. Dake strongly recommends that Dake press users obtain a copy of the current American National Standard Institute (ANSI) B11.2 standard, for a more complete understanding of their responsibilities. ANSI B11.2 states the following, relative to point of operation safeguarding: “Normally, only the employer (press user) can determine the requirements of the press productions system components, including the dies and methods for feeding. Therefore, the employer is ultimately responsible to designate and provide the point-of-operation safeguarding system.”
The standard also discusses additional responsibilities of the employer. Some of the key responsibilities are:

  • The employer is responsible for the safety, use, and care of the hydraulic power press production system.
  • The employer is responsible to consider the sources of hazards for all tasks to be implemented on the hydraulic power press production system.
  • The employer is required to eliminate or control identified hazards in the scope of their work activity.
  • The employer is responsible for the training of personnel, caring for, inspecting, maintaining, and operating hydraulic press production systems to ensure their competence.
  • The employer is responsible to provide and ensure that point-of-operation safeguarding is used, checked, maintained, and where applicable, adjusted on every production operation performed on a press production system.

A complete and current copy of the ANSI B.11.2 standard can be obtained by contacting the following:

  • American National Standards Institute

SET UP

FIRST TIME SET UP
For shipping convenience, the hoist crank was removed from the press and will need to be attached upon arrival.

  1. The press should be set on a level floor with the base angles touching the floor at all points, using shims where necessary.
  2. Bolt the press to the floor using 4 anchor bolts.
  3. Motor starter box is mounted on left upright. Have electrician connect power to motor starter. Pump can rotate in either direction.
  4. Fill the press with oil. Use Mobil DTE oil No. 24 or equivalent. Remove the NPT pipe plug from the weep hole located on the right side of the reservoir. Start to fill the reservoir using the pour spout at the back of the press. Once oil starts to run out of the weep hole stop filling and replace the pipe plug.
    • Filter all oil before adding to press* Model 5-075 requires 10 quarts of oil.
  5. Prime the pump by removing the plug on the top of the pump and filling it with oil. Wait until the oil levels equalize between the reservoir and the pump, then replace the plug and making sure the seal is tight.DAKE-5-075-Elec-Draulic-I-Press-fig-1 \(5\)
  6. Attach nose piece to ram by inserting shank into ram and tightening the set screw.

MOVING THE TABLE

CAUTION!

  1. Place the hoist crank on the lift drum shaft. Turn the hoist crank to relieve the pressure on the table pins. Keeping tension on the hoist crank, remove the table pins on at a time. After removing the table pins, turn the crank that controls the table and run it top to bottom.
  2. Ensure that the cable is tracking correctly, this means the cable should be on each of the two upper pulleys and should track back and forth on the cable drum.
    • a) If tracking problems exist, contact the Dake for instructions.
  3. Be sure the table pins are fully inserted in place before applying pressure, servicing, cable tracking, or set up for desired work opening. Always be sure to put slack into the cable before operating the press.

OPERATION

WARNING: DO NOT OVERSTROKE THE RAM. Overstroking will cause premature seal failure.
Model 5-075 maximum stoke is 10 inches.
CONTROLS

  • Three set screws (Item 100) are used to lock the workhead in the desired position along the head channels.
  • The hand crank (Item 19) is used to raise and lower the table channels to the proper work height. When desired height is reached insert the table pins, three pins on each side. o Be sure all the table pins are in place and inserted as far as they can go before pressure is applied. o Be sure to put slack into the cable before pressure is applied.
  • The handle on the left side of the workhead (Item 67) opens and closes the ball valve, which releases pressure on the ram. This valve should be kept firmly closed and only opened when it is time to move the ram to its up position.
  • The two table plates (Item 6) and two V-blocks (Item 7) are used for supporting the work in process.
  • The control handle (Item 86 & 91) on the right side of the panel regulates the speed of ram travel. The handle will return to the off position when released. It is not necessary to stop the motor after each operation.
  • The relief valve (Item 79) has been factory set to open when maximum tonnage of the press is reached. The valve should only be adjusted by a professional technician.
    • Never exceed the rated tonnage of the press.

MAINTENANCE

LUBRICATION

  • Keep all working parts of the press well-oiled for easier operation.
  • Keep a light film of oil over the entire surface of the ram to prevent rust.

CHECKING HYDRAULIC OIL LEVEL

  • Hydraulic oil should be checked and refilled as needed once a week.
  • Amount needed may vary dependent on machine use*
  • To check, open the weep hole, if oil leaks out then the press is still filled properly. If it is not, use step 4 in the “SET UP” section of the manual to add oil.

REPLACING HYDRAULIC OIL

  • Recommended to replace hydraulic oil every 6 months of machine use.
  • Amount needed may vary dependent on machine use*
  • To empty oil, remove the pipe plug located in front of the ram and use a bucket to catch the old oil. To fill use step 4 in the “SET UP” section of the manual.
  • Priming the pump is not necessary after replacing oil in the machine.

TROUBLESHOOTING

CAUTION!

  • Use extreme caution when disconnecting any parts of the machine to not introduce any dirt/dust into the hydraulic system, ensure all parts stay clean.
    • Filter any oils before adding into the machine.
  • When performing any maintenance make sure proper lockout procedure is followed.
  • High pressure fluid is present in operational hydraulic systems. Fluids under high pressure are dangerous and can cause serious injury or death. Do not make modifications, repairs or adjustments to a hydraulic system unless you are competent or working under competent supervision. If in doubt, consult a qualified technician, engineer, or contact the Dake factory.

If the press loses pressure:

  • a. Check all tubing joins for leaks and tighten tube nuts.
  • b. Leakage past the release valve (Item 67). Drain reservoir and remove packing nut (Item 66), valve rod (Item 64), and ball valve (Item 63). Clean out valve seat and reseat ball valve using a brass rod as a drift, striking sharply with a hammer. Reassemble valve rod, packing, and packing nut. Refill reservoir with appropriate oil amount.
  • c. Leakage past eductor inlet check ball (Item 60). Drain reservoir, remove large pipe plug (Item 62), valve seat (Item 61), and check ball (Item 60). Clean and inspect seat. Reset ball on seat or replace seat with new part if necessary. Reassemble with ball above the seat tightening plugs securely.
  • d. Worn leather cup or T-ring seal. If none of the previous conditions seem to have been the cause, the leather cup or T-ring may be worm or damaged. To inspect, drain oil and remove the work head from the press frame. Remove tube assembly (Item 123). Set two 4×4 blocks on the table then raise the table channels with the block up to the bottom of the reservoir applying pressure to the reservoir. Remove roller brackets from the reservoir and lower the work head using the table.

WARNING: Be sure the stroke indicator rod support is installed in the side of the piston. If not, insert 1/2″-13 stud or cap screw into the tapped hole in the piston. This will hold the piston down under spring pressure. Next remove nuts from cylinder flange and lift cylinder off piston. The piston leather or T-ring seal can now be inspected and replaced if necessary. Press may be reassembled in reverse order being careful not to damage the lip of the leather cup or T-ring seal as it enters the cylinder.
Note: A leather cup will only be in presses made before 1992 or has a serial number before 192522.

Press will not develop rated tonnage.

  • a. Dirt under ball valves. Refer to 1 – c above.
  • b. Worn leather cup or T-ring seal. See 1 – d above.
  • c. Relief valve is not set properly. This valve is located on the top side near the right end of the control block at the front of the reservoir. The valve is set at the factory to bypass oil from the pump back to the reservoir when the press reaches its rated capacity.

The load on the spring (Item 75), which governs the pressure at which the valve will bypass oil, is adjusted by turning the screw (Item 79) in to increase pressure or out to decrease pressure. Replace seal (Item 74) and cap nut (Item 78).

Note: We advise that the relief valve not be tampered with after it is set to the capacity of the press.

Nothing happens when press is operated.

  • a. If motor does not run, the electrical circuit should be investigated.
  • b. Release valve is open. Be sure to have release valve firmly closed when using press.
  • c. If the ram will come down only a fraction of its rated stroke, check the oil level in the reservoir with the ram at the top of its stroke.
  • d. Eductor nozzle is plugged. If motor labors and ram does not move when pump control knob is turned, the orifice in the eductor nozzle (item 73) may be plugged. Drain reservoir, remove tube assembly (Item 123), eductor bushing (item 70), eductor body (item 72), and eductor nozzle (Item 73). Clean out orifice with a 1/32” drill. Replace parts being sure not to install item 72 backwards. See parts drawing. Check O-ring and back-up washer (items 71A &71B) to be sure it has not been damaged.

Press is operating slow.

  • a. Improper oil. It is essential that the recommended oil (Mobil DTE 24 or equivalent) be used. Heavier oils cause a marked reduction in the ram speed.
    • Note: DO NOT USE HYDRAULIC JACK OIL.
  • b. Release valve not closed properly. Release valve must be firmly closed when using the press.
  • c. The seal on the piston rod for the 50-101 pump is worn. A worn seal will pull air into the pump causing the pump to slowly lose its prime. To test, place grease around the control rod where it goes in and out of the seal (Item 129). Then replace seal part number 26573.
  • d. The piston rod for the 50-101 pump is bent or rusted. Contact Dake for rebuilding the pump. Note: Adjustments to the pump are not necessary and the pump should not be tampered with because expensive damage could occur.

Sequence of Operation:

  1. Press Idle – Dake Elec-draulic presses are operated through lever (11) after turning the electric motor switch to “ON”. This lever operated through its range provides ram speeds from zero to the maximum rated pressing speed of the press. This is done entirely within the pump (2) and does not require a variable speed electric motor.
  2. Advance – When release valve (6) is closed, the fluid flows through the manifold and check valve (9) to the eductor (5). As the oil passes through the restricted orifice of the eductor (5). It “picks up” oil through the check valve (8), giving rapid advance.
  3. Pressing – When the ram meets resistance, check valve (8) closes and maximum pressure can be built.
  4. Return – When pressing is completed and lever (11) is returned to zero speed, check valve (9) closes and holds the hydraulic fluid above the ram until it is released back to the reservoir (3) by opening the release valve (6). The ram spring then returns the ram to its up position. In doing this the ram exerts a pressure on the oil and returns it to the reservoir through the open release valve (6).

The relief valve (7) will automatically by-pass the oil back to the reservoir (3) when the oil pressure exceeds system pressure. Check valve (9) holds pressure in the cylinder (4) when relief valve (7) is open. The relief valve (7) is made so the pressure can be reduced to 1/2 its normal operating pressure. By-pass hole in cylinder wall limits travel of ram and protects press from breakage.

INSTRUCTIONS AND PARTS

INSTRUCTIONS AND PARTS LIST FOR

  • MODEL 50-101
  • 3/4 GPM Hydraulic Pump
  • Variable Volume – Step Control

DESCRIPTION
This unit is a five-piston axial type piston pump designed for heavy-duty industrial application up to 6000 psi continuous and 8000 psi intermittent. The pump should be coupled directly to the driving source and can be rotated in either direction.

TYPICAL VARIABLE VOLUME CONTROLS

  • A) Stem Control – with control stem out (return spring), output delivery is zero gpm – pushing in on the control stem increases pump delivery from zero to the maximum gpm.
  • B) Knob Control – with the control knob adjusted out (counterclockwise rotation), output delivery is zero gpm – turning the control knob clockwise increases pump delivery from zero to the maximum gpm.
  • C) Pressure Compensated – circuit operating pressure is controlled by setting the compensator valve mounted on the pump. Turning the knob clockwise increases circuit pressure, counterclockwise decreases circuit pressure. Output delivery of the pump at zero circuit pressure is maximum gpm – when circuit pressure reaches the setting of the compensator valve pump output automatically decreases to supply the exact flow rate required by the system.

INSTALLATION

  1. Rotation – Pump shaft rotation can be in either direction.
  2. Shaft Alignment & Pump Mounting – The alignment of the pump and motor is critical, having a direct relation to pump bearing, shaft seal and coupling life.
  3. Fluid Connections – Pressure and intake line piping should correspond to port size to keep fluid velocities in an acceptable range. Do not bush down to a smaller size.
  4. Safety Valves – The high-pressure line must have a relief valve close to the high-pressure outlet to prevent damage to the pump. In a circuit using the pressure compensated pump, the relief valve should be set several hundred psi above the compensator pressure to minimize transient pressures due to compensator overtravel.
  5. Filtration – Cleanliness of fluid and components is of extreme importance in high-pressure hydraulic circuits. A suction strainer of 140 microns or less and a twice pump capacity should be used in the pump inlet line.

MAINTENANCE

  • A) Minor Repairs – Minor repairs are considered those that so not involve total disassembly of the pump. External leaks around the pump, for example, can usually be eliminated by tightening screws and/or fittings around the leakage area. Replacement of leaking shaft or O-ring seals is a minor repair that can be done in the field. The Dake service manual should be consulted for the necessary part numbers.
  • B) Major Repairs – Major field repairs can be accomplished in an emergency; however, it is recommended that the Dake factory be contacted for necessary assistance. Dake pumps are built to give long-term dependable service. If they should eventually require overhaul, factory rebuilding is recommended when possible since disassembly and assembly can damage many parts. This minimizes replacements with net savings to the user. Trained Dake personnel with complete rebuilding and testing facilities permit rapid overhaul and testing, resulting in minimal downtime for the customer as well as the added advantage of complete factory testing after repair.
