Abstract

The invention discloses an ultrasonic vibration spindle device for incrementally forming plates. The ultrasonic vibration spindle device comprises an ultrasonic generator, a shell and a coupling. The coupling is connected with the shell by shell bolts, a primary winding is connected with the ultrasonic generator by a wire, a secondary winding is arranged on the coupling, and the primary winding and the secondary winding are connected with each other by means of inductive coupling; a giant magnetostictive rod is arranged in the shell, a driving coil is arranged outside the giant magnetostictive rod, permanent magnets are arranged at two ends of the giant magnetostictive rod, magnetic conductive blocks are arranged on the permanent magnets, the magnetic conductive block which is close to the coupling is arranged on a rear cover plate, the other magnetic conductive block is arranged on a front cover plate, the front cover plate is connected with the shell by bolts, and a tool head is fixed to the front cover plate by the aid of screws. The ultrasonic vibration spindle device has the advantages that the giant magnetostictive rod is a driving element, and accordingly the problem of low output amplitude and power of the traditional piezoelectric transducer can be solved.

Description

technical field [0001] The invention belongs to the field of progressive forming of sheet metal, in particular to an ultrasonic vibration spindle device for progressive forming of sheet material. Background technique [0002] Sheet metal incremental forming is a new type of dieless forming technology. This forming technology is based on the idea of ​​"layered manufacturing" in rapid manufacturing. It discretizes complex three-dimensional shapes into a series of two-dimensional planes along the axial direction, and The corresponding trajectory is generated on the corresponding plane, and the tool head moves according to the processing trajectory during forming, so that the required shape is gradually formed. [0003] Ultrasonic Vibration Sheet Metal Incremental Forming is a sheet metal forming process in which ultrasonic vibration is applied to the tool head during the single-point incremental forming process of sheet metal. During the progressive forming process, the sheet ...
