[CN 202010653387.6] Progressive Radial Forging Device and Process of Four Hammer Head with Non-involute Complex Curved Tooth Profile at Circular Arc Tooth Bottom
[CN 202010653387.6] Four-hammer progressive radial forging device and process title for non-involute complex curved tooth profile with circular arc tooth bottom: Four-hammer progressive radial forging device and process application number for non-involute complex curved tooth profile with circular arc tooth bottom: CN 202010653387.6 Applicant: Xi 'an Jiaotong University Application Date: 2020-7-8 Patent Type: Invention Application This invention belongs to the technical field of plastic processing, specifically, it relates to a circular arc tooth bottom non-involute complex curved surface tooth shape four-hammer progressive radial forging device and process. A four-hammer progressive radial forging device with non-involute complex curved tooth profile at the bottom of a circular arc tooth includes four radial forging hammers and a clamping device. The four radial forging hammers are circumferentially arrayed at a certain angle in space. The radial forging hammer is used to form the non-involute complex curved tooth profile of the bottom of the circular arc tooth; the clamping device is used to realize the axial feeding, rotation and axial withdrawal of the workpiece. The invention uses a plastic forming method to form a circular arc tooth bottom non-involute complex curved surface tooth-shaped part, the forming efficiency is high, the formed part tissue fiber is continuous, especially the surface processing hardening phenomenon of the part after cold forging is obvious, the surface strength is increased, and the reliability of the part is improved.
