Auxiliary incremental forming device heating metal plate by using electrical discharges

Abstract

The invention relates to an auxiliary incremental forming device heating a metal plate by using electrical discharges. The auxiliary incremental forming device is characterized in that a workpiece isfixed on a support, and the support is fixed on a machine tool. During forming machining of the metal plate, a vibrator drives an electrical discharge anode to vibrate together, then the electrical discharge anode is in contact with the plate frequently and alternately, the high-strength electrical discharges are generated, then the plate is locally heated, so that machining conditions are greatlyimproved, and the auxiliary incremental forming device is especially used for a thick plate; and the auxiliary incremental forming device has the advantages that the structure is simple, the work isreliable, the installation operation and the maintenance are convenient.

Description

technical field

[0001] The invention relates to the field of mechanical manufacturing and processing, and more specifically relates to an electric spark heating metal plate auxiliary progressive forming device. Background technique

[0002] Due to its advantages of high degree of automation and no need for molds, incremental forming of sheet metal has been widely used in automobile manufacturing, aerospace, medical treatment, art sculpture and other fields. Most of the incremental forming of sheet metal is carried out at room temperature. Due to the uneven flow of metal during forming, it is easy to produce defects such as wrinkles and cracks, especially for high-strength, high-hardness and difficult-to-process materials such as stainless steel, magnesium alloys, and titanium alloys. , forming defects are particularly significant. Contents of the invention

[0003] The present invention draws on the principle of electric discharge machining, and the present invention incl...
