Problems solved by technology

In recent years, the emerging punching riveting connection adopts hollow rivets, which will pierce the upper plate during the connection process and cause damage to the plate.
In addition, this kind of hollow rivet is generally made of different materials from the plate, which is prone to electrochemical corrosion and reduces the connection quality

Abstract

The invention provides an electromagnetically-driven spin lock type plate connecting device. The electromagnetically-driven spin lock type plate connecting device comprises a supporting frame, an electromagnetic driving device, an electromagnetic moving plate, a stamping head, a guide plate, a bottom die and a guide structure; the supporting frame comprises a top supporting plate, a guide plate and a bottom supporting plate; the top supporting plate and the guide plate are fixedly connected through two connecting pairs, the guide plate and the bottom supporting plate are fixedly connected through two hollow cylinders, and the electromagnetic moving plate is arranged between the top supporting plate and the guide plate; the stamping head is arranged below the electromagnetic moving plate; and the electromagnetic driving device is matched with a guide structure to enable the electromagnetic moving plate to drive the stamping head to rotate and press downwards, so that a plate is spun into a cavity of the bottom die. The invention further provides an electromagnetically-driven spin-locking type plate connecting method, plate spinning connection can be achieved through electromagnetically driving, the connecting precision and the structural strength are high, auxiliary materials are not needed in the connecting process, and the connecting cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of plate connection, in particular to an electromagnetically driven twist-lock type plate connection device and method. Background technique [0002] With the popularity of lightweight vehicles, more and more lightweight sheets (such as aluminum alloys and magnesium alloys) are widely used in the body. These lightweight materials not only reduce the weight of the body, but also increase the strength of the body to a certain extent. In recent years, the connection of these lightweight materials has become a research hotspot. [0003] The traditional plate connection methods mainly include welding, gluing and rivet connection. There are many branches of welding technology, such as resistance spot welding, submerged arc welding and carbon dioxide gas shielded welding. The welding connection technology mainly generates local heat, melts the metal, realizes the mutual flow of materials, and cools to form a wel...
