Hot Extrusion Process and Die Design for the Sleeve

给出了套筒零件实用的热挤压工艺和模具结构,论述了模具的工作过程及凹模与凸模设计。该模具通过更换凸、凹模,便可生产不同规格的反挤压杯形挤压件,提高了模具利用率,降低了生产成本。

A practical hot extrusion process and die structure was presented. The operational principle and the design of teme die and cavity die were discussed. Different sizes of inverted extrusion cupulate extrusions were manufactured by replacing the teme die and cavity die, so the ratio of utilization of the die was raised, and the cost of manufacture was lowered.
