Description

B1.282 Hydro-cylinder with optional stroke end cushioning

Double-acting hydro-cylinders with connecting dimensions according to DIN ISO 6020. Only exception is the shorter overall length. On request also available in the longer version as per DIN ISO 60 20. The piston rod is provided with an external thread. For fixing, the front and back part of the body is provided with 4 internal threads.
The adjustable stroke end cushioning avoids a too hard stop of the piston in the cylinder body with the following applications:

1. High piston speed

2. Additional load at the piston rod

3. If an external stop cannot be provided to compensate the additional load

Application examples

Application example 1

Injection mould

Cycle (portrayed in simplified terms)
1. Mould closed, injected
2. Toothed rack retracts, threaded spindle is moved out
3. Limit switch gives signal "open mould"
4. Mould opens
5. Workpiece will be ejected
6. Mould closes
7. Toothed rack extends, threaded spindle is moved in
8. Limit switch gives signal „Substance to be injected“
9. Substance is injected
1. New cycle

Application example 2

Injection mould

Cycle (portrayed in simplified terms)
1. Mould closed, injected
2. Mould opens
3. Hydraulic block cylinder pulls the core out of the mould
4. Limit switch gives signal "ejector system forward"
5. Ejector system forwards
6. Workpiece falls
7. Ejector system backwards
8. Limit switch gives signal "Insert core"
9. Hydraulic block cylinder pushes the core into the mould
10. Limit switch gives signal "close mould"
11. Mould closes
12. Substance is injected
1. New cycle
