Comparison of TOX-Powerpackage and hydraulic cylinder

TOX Powerpackage drive

Typical hydraulic press drive

1. Costs

1.1 Investment:

Relatively low to medium costs; inexpensive pneumatic controls: simple mounting (examples):

24 kN € 1.900,-

80 kN € 2.270,-

300 kN € 4.040,-

1000 kN € 10.600,-

1. Costs

1.1 Investment:

Medium to high costs. Complicated controls and installation.

24 kN € 3.426,-

80 kN € 21.730,-

300 kN € 21.730,-

1000 kN € 21.730,-

1.2 Process speed: Based on cycle rates:

for 24 kN 100 strokes/min

for 80 kN 80 strokes/min

for 300 kN 50 strokes/min

for 1000 kN 30 strokes/min

1.2 Process speed:

for 24 kN 80 strokes/min

for 80 kN 60 strokes/min

for 300 kN 30 strokes/min

for 1000 kN 20 strokes/min

1.3 Maintenance: Easy to exchange; compact design; minimal wear; seals last many millions of cycles. Simple maintenance consists of oil refilling and bleeding when low oil level indicator pops out.

1.3 Maintenance: Change of oil and filters required periodically. Oil leakage, contamination requires continuous maintenance. Complicated installation and plumbing.

1.4 Energy Consumption per Stroke: in litres (CF) normal air:

for 24 kN 4.75 l (.17 CF)

for 80 kN 16.00 l (.57 CF)

for 300 kN 59.00 l (2.08 CF)

for 1000 kN 198.00 l (7.00 CF)

1.4 Energy Consumption per Stroke: Depending on controls. For simple controls and small loads, up to 80 kN/80 strokes/min. Very complicated controls required for large units.

2. Quality

Easy on tooling due to soft touch during approach stroke. Independent speed controls for approach, retract and power strokes. Force can be precisely controlled with a pressure switch and monitored with a gauge. Workpiece tolerance stackups are compensated automatically by the resistance activated power stroke. Stroke adjustment is not required when changing tooling. Precise rod guidance is provided by supporting it on both ends.

2. Quality

Low-force approach stroke is possible only with specialsystems. Approach and retract speeds are adjustable;power stroke can be controlled with pressure switch. Force available throughout stroke, compensates for variations in part tolerances.

3. System Flexibility

Units available in many stroke lengths. In specialcases, the units can be stroked repeatedly to pressassemblies together that require longer powerstrokes than available.

3. System Flexibility

Force available throughout stroke.

4. Environment

Ideal for sterile room applications. Low noise due to soft touch. Low air consumption also provides lownoise levels of exhausts.

4. Environment

High noise levels. Contamination, oil leakage. Heat generated by pump.

5. Disadvantages

Units are long for very long power stroke requirements(split execution can be used in such cases).

5. Disadvantages

High energy consumption. Leakage.

The parameters were considered for comparison of the different systems: 6 bar air pressure, 60 mm total stroke, 3 mm included power stroke, press force 24 kN / 80 kN / 300 kN / 1000 kN
