Description

Discharge coil for electromagnetic riveting gun and manufacturing method thereof technical field The invention relates to a discharge coil, in particular to a discharge coil for an electromagnetic riveting gun, and also to a manufacturing method of the discharge coil. Background technique Electromagnetic riveting technology has been widely used in the aerospace field. As the core component of electromagnetic riveting equipment, the discharge coil has an important impact on the performance of electromagnetic riveting equipment. Electromagnetic riveting equipment generally has two coils. The primary coil is generally a wound multi-turn pie-shaped coil, also known as a discharge coil. The secondary coil is generally an aluminum or copper plate with a certain thickness. The discharge coil is a key component of electromagnetic riveting equipment, and its working conditions are very harsh. When riveting, the discharge coil needs to bear the impact current of tens of thousands o...
