The invention discloses a circular working collecting device of metal forming machinery. The circular working collecting device comprises a base and supporting rods, an outer shell is installed on theupper part of the base, an anti-corrosion layer is arranged on the outer side of the outer shell, a collecting box is installed on the left side of the outer shell, classifying boxes are installed onthe inner side of the collecting box, a feeding port is formed in the right side of the outer shell, and heat emission holes are formed in the upper part of the feeding port. According to the circular working collecting device of the metal forming machinery, the base, the outer shell, the anti-corrosion layer, the collecting box, the classifying boxes, clamping hands and a telescopic strip are arranged, the clamping hands can clamp materials after being machined, the telescopic strip performs retraction on the telescopic hands upward, then the materials are conveyed to the collecting box through an inclined plate, the classifying boxes in the collecting box can perform classified storage on the materials after being machined, later processing of users is facilitated, during long-term operation of the collecting device, the heat emission holes can perform dissipation on inner heat, inner part damage caused by inner excessively high temperature can be prevented, a conveying belt can drive the materials to be subjected to automatic circular machining, and the labor is saved.
