The power set of the TROMBOLINE consists of an hydropneumatic intensifier and a
manually operated mechanical unit.
|
|
|
The working cycle is split up into three phases:
1. Approach stroke
2. Slip clutch stroke of intensifier
3. Work stroke with hydropneumatic force
|
|
 |
|
|
|
|
|
|
1. Approach stroke
The level operates the down stroke of the piston rod through a rack-and-pinion
device. It allows tha approach of the tool to workpiece. |
|
 |
|
|
|
|
|
|
2. Slip clutch stroke of intensifier
The continuing movement of the lever, engages the intensifier. It operates with
a friction clutch system.
|
|
 |
|
|
|
|
|
|
3. Working stroke with hydropneumatic force
During further down stroke of the lever, the hydropneumatic intensifier carries
out the working stroke, always with friction engaged. The release of the lever
causes the return to starting position.
|
|
 |
|
|
|
- The release of the lever causes the return of the piston rod to starting position (T.D.C.) by means of an helical spring.
- The hydropneumatic intensifier operates at any point of the stroke.
- The hydropneumatic working stroke can be operated several times by resting on workpiece. (For multiple working strokes. Example 10+10+10).
