Design, study and development of new equipment for sheet-metal forming

Abstract

A new facility for sheet-metal forming ensuring forming with heating of a workpiece to the temperature interval of warm or hot machining is designed and developed. The facility contains a case connected to a die where a working cylinder and a combustion chamber, separated from each other by the piston, are placed. Heating and deformation of a stamped workpiece is made under the influence of combustion products of fuel mixes in a working cylinder and dies. The distinctive feature of this unit is that the final forming stage ensures considerable increase of deforming effort that considerably enhances its technological capacity. Practical testing of the designed unit was performed. High quality products were obtained, which makes it possible to recommend this facility for use in small-scale production.
