Abstract

The invention discloses a portable low-voltage electromagnetism riveter applied to the electromagnetism riveting technology, which mainly provides an electromagnetism riveting method for the work condition with poor openness of a riveting and operation environment of a medium-small rivet and high requirement on the flexibility of riveting process, and changes the current situation of large volume, heavy mass and inflexible operation of the existing electromagnetism riveter. The technical structure of the invention is composed of a front cover, a shell, a rear cover, a spring slideway, a rear cover flange, a coil, an amplifier, a punch, a rubber shock absorber, a damping spring and other components; under the low pressure condition of 300-1000V, the riveter can be used for carrying out the riveting of a high-strength aluminum alloy riveter with the diameter of 5mm or the riveting of the riveter with medium-small diameter made of other metal materials. The total mass of the riveter is as light as 3.0-4.5kg, is convenient to handheld operation, has remarkable damping effect, low recoil and high operation flexibility and reduces the labor intensity.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a portable low-voltage electromagnetic riveting gun applied to the electromagnetic riveting technology. Background technique [0002] Riveting is a mechanical connection technology widely used in aerospace, automobile, electronic appliances and other manufacturing fields. It mainly includes hammer riveting, pressure riveting and electromagnetic riveting and other process forms. [0003] Hammer riveting is a commonly used riveting method. When riveting, use the impact force to hit the head of the rivet rod several times in succession, so that the rivet material flows in the radial direction, forming the riveted head of the connected parts. The process characteristics are: the required impact force is large; There is a large vibration; the force on the head of the rivet rod is uneven, and the product quality is unstable; the surface quality of the riveted...
