  • Sheet metal processing machines having a chip suctioning device and methods for detecting a malfunction in the chip suctioning device
    Patent number: 10247636
    Abstract: Sheet metal processing machines having a chip suctioning device and a control device are provided. The chip suctioning device has a chip space connected to a die orifice of a punching die for collecting chips, wherein the chip space is provided with a chip flap and a extraction line, and the extraction line comprises at least one sieve, a vacuum generator, e.g., an extraction fan, connected to the extraction line for generating a vacuum in the chip suction device, and a vacuum sensor, connected to the extraction line between the downstream last sieve and the vacuum generator, being configured to supply signals to the control device.
