Retraction system for multihyphen;anvil presses

摘要

A hollow guidehyphen;pin system is described for retraction of the hydraulic rams of multihyphen;anvil presses that saves weight and machining costs and improves mechanical proportions. The system also unclutters the anvil region, providing more access. The use of inverted rams and right/lefthyphen;hand thread tiehyphen;bars and bases further reduces weight and cost.
