摘要

A stamping machine has an actuator moving an upper plate carrying a stamp toward. The upper plate is mounted on guides and moves the stamp through an opening in an intermediate plate to a lower plate supporting a workpiece. The stamp has lower cutting edges that operate as the stamp descends and upper cutting edges as the stamp ascends. The intermediate and lower plates may be fixed to the guides. The opening in the intermediate plate corresponds to the shape of the stamp. The workpiece is a tubular section.
