Embodiment Construction

[0009] The production and processing process of the double-drum type blind rivet: firstly, a special machine is used to pre-process two grooves (1-1) on the mandrel nail (1), and there will be two grooves (1-1) ) mandrel nail (1) for cleaning and annealing treatment, and then use a self-made special machine and mold to place the The metal aluminum material is squeezed inward at the two grooves (1-1) and pressed at the same time to form a metal double drum (2) and a double drum type blind rivet. It has high smoothness, clean and beautiful appearance, novel shape and wide range of applications. Due to the use of self-made special machines for production, the production efficiency is improved. It is suitable for mass production and meets the needs of the market.

[0010] According to above-mentioned making promptly constitute the present invention---a kind of double-drum type blind rivet.

Description

technical field [0001] The invention relates to a coupling rivet for fixing components, in particular to a double-drum type blind rivet. Background technique [0002] The common rivets currently used are limited by the thickness of the riveted parts. For example, the thicker the riveted plate, the lower the strength of the rivet and the lower the safety. Therefore, there are problems such as single use and rough appearance. With the development of my country's national economy and the improvement of people's living standards, the decoration and decoration design projects required in the vast urban and rural areas have developed rapidly. At present, there is an urgent need to provide a large number of rivets that meet the needs of decoration and decoration design projects. Therefore, in order to meet the needs of the market, it is very necessary for the country to develop a double-drum type blind rivet with dual functions, high strength, and novel and beautiful appearance. ...
