Assembly for heating workpieces before shaping in a press, e.g. high tensile steel sheets for automobile bodywork components, has a kiln with a jet field and fans to give the workpieces a convective heating action

摘要

To raise the temperature of workpieces (10), prior to heat shaping, they are passed through a kiln (30) with a jet field (20). The jet field has a number of openings for the delivery of beating fluid streams to heat the workpieces by a convective action, with fans (40) to circulate the heat. The heated workpieces are transferred by a gripper (80) to a shaping press (90).
