Device for riveting sheet metal

Abstract

The invention discloses a riveting device for sheet metals, which is used for performing riveting processing on the sheet metals which are overlaid in two layers or a plurality of layers. The device is provided with a riveting punching head (1) and a riveting concave die (2) which are connected with a gas-liquid pressurization system respectively; and in the riveting processing state, the riveting punching head (1) is pressed into one surface of the sheet metals which are overlaid in the two layers or the plurality of the layers, and protrusions formed on opposite surfaces of the sheet metals are pressed into a concave cavity of the riveting concave die (2). Due to adoption of the technical proposal, the riveting device for the sheet metals is easy to detect and control the connection quality, can achieve the aim of detection by the general detection mode, has stable riveting parameters which are difficult to fluctuate, can not generate pollutant and radiation which pollute the environment and harm the body health due to riveting, and avoids welding dropping of surface claddings and even components of sheet metal pieces caused by welding. Compared with the prior riveting technology, the riveting method is simple and has low cost.

Description

technical field [0001] The invention belongs to the technical field of metal sheet material processing, and more specifically, the invention relates to a metal sheet riveting device. Background technique [0002] In mechanical structures, welding is generally the most widely used connection technology for sheet metal, but the disadvantages of welding are also obvious. Its equipment is expensive, the connection cost is high, it is difficult to connect multi-layer plates and plated plates or aluminum, copper and stainless steel plates, welding of galvanized steel plates, welding of high-strength steel plates and welding of plated steel plates, often Destroying the surface coating or even welding parts off will affect the corrosion resistance of the plate, and there will be mechanical stress concentration and difficult detection. [0003] There are many existing rivetless riveting technologies, such as Tox riveting of Tox company. But their common disadvantage is that the mol...
