The utility model discloses a new energy vehicle charging connector body precision forging forming die which comprises a connecting handle part, a head part extending for a set distance along an arc path, a prefabricated stepped hole formed in the back arch position of a connecting area of the connecting handle part and the head part in an inwards-concave mode and perpendicular to the end face of the head part, and a lower die and an upper die which can be opened and closed. The lower die and the upper die form a cavity with a charging connector body in a supine posture, the surface of the cavity used for forming the end face part of the head is horizontally arranged, located on the upper die and located at a high position, and a containing cavity used for containing an extrusion head and a sliding cavity used for guiding the extrusion head in a sliding mode are further formed in the lower die. The extrusion head is used for stretching into the cavity to form a prefabricated stepped hole and a head after the lower die and the upper die are closed.

The invention relates to the technical field of rolling forming, and discloses a rolling double-point incremental forming device and method.The rolling double-point incremental forming device comprises a rolling rod, a plate is fixedly arranged on the inner wall of a blank holder, when the rolling rod moves, a fixed shaft is driven to move, a roller synchronously moves along with the fixed shaft, and in the moving process of the rolling rod, pressure is applied to the roller, so that the rolling rod is driven to rotate; according to the incremental forming method, the rolling wheel rolls on the surface of the plate, pressure is applied to the plate, the surface of the plate is gradually recessed by means of continuous rolling of the rolling wheel, the quality of the surface left when the tool head makes contact with the plate is improved, forming force and forming defects in the forming process are reduced, and the application range of incremental forming is further expanded.
