Air/oil power unit for use with hydraulic rollblocks max. operating pressure 1,740 psi
Applications: The HCR-PA-23X01 is an air driven hydraulic pump package. It is designed for intermittent use and the actuation of die lifters with operating pressure of 550 to 1,740 psi (40 to 120 bar). Description: The pump is actuated by the manual air toggle or solenoid operated valve located at the base of the pump. It has a 40 cu. inch reservoir, with 20 cu. inch usable capacity. The out-put pressure (20:1) is controlled by the adjustable air regulator. A safety circuit relief valve reduces possible pressure intensification caused by overloading the rollblocks. A return line check valve keeps balls or rollers that are not under the die up during stamping. Note: Minimum inlet air pressure is 60 psi. Air supplied to pump must be clean, dry and non-lubricated. Air filter is included.

Hydraulic power units Series D 8.0115 with 0.82/2.1/3.5 l/min
Q P
Applications:
These power units are especially suitable for the operation of small to medium-sized hydraulic clamping fixtures. Maximally 2 clamping circuits for single or doubleacting cylinders are available, that can be controlled independently of each other. This means "shuttle machining" is possible, i.e. that during machining of the workpiece in one fixture, workpiece change on the second fixture can be made.
Description:
A special feature is the mounting of pump and electric motor in the reservoir, so hydraulic and electric control can be arranged in a space-saving way and easily accessible on the reservoir cover. The modular design enables a multitude of control variants. The radial piston pump is available with 3 different flow rates and operating pressures. To allow an energy-saving intermittent cycling, only leakage-free poppet valves are used.
Important notes:
These power units are exclusively designed for the industrial use of pressure generators for hydraulic clamping fixtures that allow intermittent cycling (see example).
Clamping fixture / Clamping elements
Advantages: Very compact design Energy-saving intermittent cycling Many control variants Electronic pressure switch Digital pressure display Quick pressure adjustment by teach-in function Electric control optimally adapted High-quality leakage-free poppet valves Pressure generator also without valves available Useful accessory already mounted Alternatively manual switch or foot switch Ready for connection*
* Delivery The power units are delivered ready for connection. i.e. after filling of hydraulic oil and connection of the hydraulic and electric lines they are ready for operation.
All connected hydraulic components must be leakage-free and designed for the maximum operating pressure of the power unit. The power unit supplies very high pressures. The connected clamping cylinders generate very high forces so that there is a permanent danger of crushing in the effective area of the piston rod. The manufacturer of the fixture or the machine is obliged to provide effective protection devices. Installation, start up and maintenance have to be made according to the supplied operating instructions by authorized experts.

Cycle time
In this example of a hydraulic clamping fixture, the running time of the electric motor corresponds to the clamping time, which is only a few seconds. In standby mode the power consumption is relatively low (see Electrical characteristics). The conditions are leakage-free clamping elements, valves and accessories. The pressure control is made by an electronic pressure switch, that switches on the electric motor for a short time in case of a pressure drop.

Oil level and temperature control "T" S1
M
The oil level and temperature control is installed in the reservoir cover and electrically connected to the control box. In case of an error message, the control LED below the main switch is lit. Possible errors: 1. Oil filling quantity < 2.3 l Shortage 0.7 l below the minimum oil level gauge. Required refilling quantity min.1.5 l 2. Oil temperature > 63 °C Important note! As long as the error message is showing, the electric motor will no longer start to avoid damages due to overheating. This means that in the case of a pressure drop, the pump does not deliver !!! Recommendation Above all, with automated operation the oil level and temperature control should only be used for machine safety in combination with pressure switches. This is the only way to ensure that during the switch-off of the electric motor the workpiece machining will be interrupted in the case of a pressure drop of more than 20%.

The hydraulic control is designed for direct manifold mounting without pipes and consists of the following components: The connecting block with pressure relief valve to adjust the desired operating pressure. The maximum operating pressure (chart page 5 of this section) is mechanically limited in the factory. Series mounting plate with electronic pressure switch and digital pressure display to adjust the switch-off pressure for the electric motor. The adjustment is made in teach-in mode independent of the adjustment of the pressure relief valve. A pressure drop of approx. 10% will cause the pump motor to start again. Series mounting plate with directional control valve for control of single or double-acting cylinders. Alternative: Series mounting plate with directional control valve and pressure switch for machine safety (see page 5 of this section).
Valves
Only leakage-free poppet valves are used to allow the energysaving intermittent cycling (see page 2 of this section). The electric control is designed for maximally two solenoid valves. Single-acting cylinders One 3/2 directional control valve per clamping circuit is directly operated by a manual switch or a foot switch. Double-acting cylinder The 4/2 directional control valve is a combination of an electrically and a hydraulically operated 3/2 directional control valve. The control is made by a manual switch or a foot switch. Operation of two clamping fixtures The control enables the operation of two clamping fixtures by means of two manual switches or two foot switches. Prerequisite is the same operating pressure of both fixtures. Safety in case of power failure The solenoid valves are de-energized in "clamping position". In the case of power failure this switching position is remained and thereby also the hydraulic pressure in the clamping line. A pressure drop is only to be feared with leaking clamping elements or valves.

Relative duty cycle

tSt
Load (Pressure)
Hydraulic control
Start
tB = Running time of the electric motor from start to switching off (clamping time) tSt = Downtime (workpiece machining time) tS = Cycle time The relative duty cycle is % ED =
tB · 100 = tB + tSt
tB · 100 tS
The maximum duty cycle is a function of the motor load. Apart from the load, the motor winding temperature of the submerged motor is in principle dependent on oil temperature and oil level. With maximum oil level, the complete winding is submerged in oil and optimally cooled. With decreasing oil surface a part of the winding is in the air. Since air is a poor heat conductor, the winding temperature increases considerably. Therefore the load of the motor must be reduced. The following chart indicates the relative cycle time as a function of the oil level in the reservoir. The maximum oil temperature of 60°C must not be exceeded (see "Oil level and temperature control").
