Multi Step Continuous Performing-Forming Roll Forging Technology of Slip-Joint Pliers

The plastic deformation technological analysis of slip joint pliers, the design of roll forging drawing, the calculation of the section diagram and diameter diagram of the billet, the determination of roll forging working step, the selection of billet dimension ,the distribution of deformation amount in each working step and the calculation of billet dimension in each working step is described. The productive process of performing forming roll forging technology of slip joint pliers is introduced. The advantages replacing traditional technology with multi step continuous roll forging is also elaborated.
