Abstract

The invention relates to an electromagnetic riveting device for a large-size thin-walled workpiece and a riveting method. Primary electromagnetic riveting equipment in the market at present has the problems that the riveting equipment is complex in structure, low in efficiency, high in processing cost, unstable in riveting quality, large in labor intensity, only suitable for some workpieces of simple structures, is great in recoil force and the like, and is limited greatly in practical engineering applications. The electromagnetic riveting device comprises a bottom plate. A group of strut screws are fixed to the bottom plate, a bracket system and an upper plate are mounted on the strut screws, the bottom of the upper plate is connected to a connecting seat, the connecting seat is arrangedon the outer side of an upper pressure block of a spring in a sleeving manner, the upper pressure block of the spring is fixedly mounted on a center guide bar, a reset spring is arranged between the upper pressure block of the spring and a lower pressure block of the spring, the reset spring is mounted on the outer side of the center guide bar in a sleeving manner, a guide bar bushing is arrangedon the outer side of the center guide bar in a sleeving manner, the guide bar bushing is connected to the lower pressure block of the spring, and the center guide bar is connected to a divided insertblock. The electromagnetic riveting device is used for electromagnetically riveting the large-size thin-walled workpiece.

Description

Technical field: [0001] The invention relates to an electromagnetic riveting device and riveting method for a large-size thin-walled workpiece. Background technique: [0002] With the growing call for energy saving and emission reduction, the manufacturing industry has more and more urgent requirements for lightweight, and the role of various lightweight materials in the industrial field is becoming more and more important. Traditional technologies challenged. [0003] Electromagnetic riveting provides a high-intensity pulse current to the discharge coil through a typical LRC discharge circuit, and then induces a mutually repelling eddy current magnetic field around the discharge coil and the driver piece. The electromagnetic riveting process does not produce any emissions during the production process. The whole process generates less heat, no waste gas, no sparks, no condensed water, no consumption of auxiliary materials, low carbon and environmental protection, low power...
