Scrap cleaning device

The utility model provides a chipping cleaning device which is used for cleaning chippings generated by die stamping and comprises a chipping channel pipe, a vacuum air suction device installed on the chipping channel pipe and an air pipe used for leading in a compressed air source. The air pipe is communicated with the vacuum air suction device and the chipping channel pipe, so that when the vacuum air suction device generates negative pressure in the chipping channel pipe, air and chippings at an inlet of the chipping channel pipe flow to an outlet of the chipping channel pipe along with a compressed air source in the air pipe. According to the utility model, the debris channel pipe, the vacuum air suction device and the air pipe used for leading in the compressed air source are arranged, and the Venturi principle is utilized, so that debris cleaning is realized. The whole device is simple in gas circuit structure, easy to apply practically, not easy to damage and long in service life; in addition, the comp
