Aerial layout punch line wiring duct device

The utility model relates to the technical field of wire ducts. The utility model relates to a device, in particular to an overhead punch line wiring duct device. The device comprises a wire duct supporting assembly, a main wire duct and a plurality of sub-wire ducts, one sub-wire duct is fixedly installed at the top end of each punch, the end, away from the punch, of each sub-wire duct communicates with the main wire duct, the wire duct supporting assembly is fixedly installed on the bottom end face of the main wire duct, and the wire duct supporting assembly is fixedly connected with the ground to support the main wire duct to be suspended; compared with the prior art, the main wire groove is erected in the air through the wire groove supporting assembly, the situation that the wire groove occupies too much ground space is avoided, a worker cannot touch a cable or a wire groove of a punching machine when walking in a workshop, the wire groove device is safer, waste materials and oildirt cannot be accumulate
