Thrust bearing block stamping die

Abstract

The invention relates to a thrust bearing block stamping die. The thrust bearing block stamping die comprises an upper die base, a lower die base, guide posts connecting the upper die base and the lower die base and guide sleeves, and further comprises a necking part pushing module. The necking part pushing module comprises a cone fixing push block and a cone expansion structure, wherein the conefixing push block is fixedly connected with the upper die base; the lower surface of the cone fixing push block is uniformly provided with a plurality of first protrusions with slope surfaces; a locating sleeve is fixedly connected with the lower die base; a plurality of necking part pushing devices are movably connected to the outer wall of the locating sleeve through stripper bolts; the cone expansion structure comprises a cone, an expansion module and a clamping plate; and the upper end of the cone is arranged on the locating sleeve, and the lower end of the cone is provided with the clamping plate. The thrust bearing block stamping die conducts necking stamping on the upper edge of a thrust bearing, the technological process is greatly reduced, the manufacturing time is shortened, pollution to the environment is reduced, and the operating cost is reduced. A workpiece stamped through the thrust bearing block stamping die is compact in structure, free of the defects such as shrinkagecavities, pores, residues and cracks. The stamping mechanical performance of the workpiece is improved, and the quality of the workpiece is greatly improved.
