Electromagnetically driven twist-lock plate joining device and method

Abstract

The invention provides an electromagnetically driven twist-lock plate connecting device, comprising: a supporting frame, an electromagnetic driving device, an electromagnetic moving plate, a stamping head, a guiding plate, a bottom mold and a guiding structure, and the supporting frame includes a top supporting plate, The guide plate and the bottom support plate, the top support plate and the guide plate are fixedly connected by two connecting pairs, the guide plate and the bottom support plate are fixedly connected by two hollow cylinders, and the electromagnetic moving plate is set between the top support plate and the guide plate; the stamping head is arranged under the electromagnetic moving plate, and the electromagnetic driving device cooperates with the guide structure so that the electromagnetic moving plate drives the stamping head to rotate and press down, and the The plates are spin-pressed into the cavity of the bottom mold; the present invention also provides an electromagnetic-driven twist-lock plate connection method, which can be connected by electromagnetic-driven plate spinning, with high connection accuracy and high structural strength, and the connection process does not require Auxiliary materials, effectively reducing the connection cost.

Description

Technical field [0001] The present invention relates to the field of sheet metal connection, and in particular, to an electromagnetic driven con lock sheet connection apparatus and method. Background technique [0002] With the popularity of lightweight, more and more light sheets (such as aluminum alloy and magnesium alloys, etc.) are widely used in the car. 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, these lightweight materials have become the hotspots of research. [0003] Traditional sheet connection methods mainly have welding, glue and rivet connections. Welding technology has a lot of branches, such as resistance spot welding, submerged arc welding, and carbon dioxide gas protection welding. The welded connection technology is mainly by generating local heat, melting the metal, achieving mutual flow of the material, and cools the welding connection point. Welding techno...

AI Technical Summary

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
