Hydropneumatikzylinder für Schneidmesservorschub
Initial situation
When cutting wound materials such as packaging tapes, films or composite materials, cutting blades must be moved precisely and at a constant speed. Uneven movement can impair cutting quality, particularly with materials that exhibit varying or fluctuating cutting forces. At the same time, it should be possible to flexibly adjust the rapid traverse and working stroke to suit the specific cutting process.
Objective
The aim was to develop a bespoke hydro-pneumatic cylinder that combines rapid feed with a precisely controllable and constant cutting speed. The rapid traverse and power stroke were to be adjustable independently of one another in order to cater optimally for different materials and cutting requirements.
Our solution
We developed a customised hydro-pneumatic cylinder to drive the cutting blade of the cutting machine. Separately adjustable throttles allow the rapid traverse and working speeds to be individually adapted to the respective process.
Whilst the rapid traverse ensures quick positioning of the cutting blade, the hydropneumatic cylinder maintains a smooth and constant cutting speed during the working stroke, even when cutting forces fluctuate. This enables even challenging composite materials, such as those made of rubber and steel, to be cut precisely and with a uniform cut profile.
