Definitions
- the present invention relates to a device for ejecting formed parts, in particular those made of sheet metal, from a forming tool with a plunger movably guided in the forming tool in a guide tube and loaded in the ejection direction by a spring.
- Such devices are known and are also referred to as feather pillows. Compression springs are regularly used as springs in such spring cushions.
- a spiral spring is used as the tension spring and is used such that the guide tube and the tappet are arranged essentially within this spiral spring.
