The invention discloses a handheld electromagnetic self-piercing riveting device. The upper portion of a riveting gun shell is in an opening shape, an electromagnetic coil is fixedly installed in theriveting gun shell, and a rear cover is fixedly arranged at the opening in the upper portion of the riveting gun shell in a covering manner. A rubber mat is fixedly clamped between the rear cover andthe electromagnetic coil, the lower portion of the riveting gun shell is provided with a guide barrel, the lower portion of an amplifier is provided with a guide pillar, and the guide pillar is movably inserted in the guide barrel of the riveting gun shell. A spring is arranged on the outer side of the amplifier in a sleeved manner, the lower end portion of the spring props against the inner wallof the riveting gun shell, and the upper end portion of the spring props against the amplifier. A drive piece is fixedly installed on the upper end portion of the amplifier and is in fit with the electromagnetic coil, and a punch is fixedly installed on the lower end portion of the guide pillar. The handheld electromagnetic self-piercing riveting device has the advantages of being good in rivetingeffect, high in efficiency, easy to control and the like, and riveting force is offset inside a system, and riveting is safe and reliable.
Description
technical field [0001] The present invention relates to the technical field of riveting devices, more specifically to the technical field of electromagnetic riveting devices. Background technique [0002] Riveting technology is a method of connecting two or more parts with one rivet, which has the advantages of easy operation, reliable connection strength and no pollution. Electromagnetic riveting is a riveting process using electromagnetic force loading. Compared with traditional riveting, it has the advantages of high joint strength, uniform interference and high work efficiency. It is currently widely used in the aerospace field. Traditional riveting technology requires pre-punching the riveting materials before connecting them with rivets. The process is complex, inefficient and difficult to automate. Self-piercing riveting technology is a connection process that adopts hydraulic or servo motor loading method to punch semi-hollow rivets, and then expands the nail legs t...
