The only way to form the structural parts of sheet metal processing is to connect. All kinds of parts are connected into the overall structure according to a certain structural form and corresponding position. Usually, mechanical connection methods such as biting, threaded connection and expansion are adopted, or welding and bonding are adopted.
The following is the riveting connection method and selection of the sheet metal structure:
Forms of riveting joint: lap joint, butt joint, Angle joint, plate riveting, turning hole riveting;
A. Lap joint method, characteristics and application: lap a piece of plate or section steel on another steel plate for riveting, can be used for bearing heavy structure, and adopt;
B. Docking method, features and application: place two steel plates or section steel joints on the same plane, and rivet the joints together with the cover plate as the connector. Can be used to support heavy structures,
And adopt half round head solid rivet;
c, Angle connection method, characteristics and application: the two plates are perpendicular to each other or connected at a certain Angle, and the Angle steel is used as the connector at the joint. There are two forms, one side and two side.
Can be used to bear heavy structure, and adopt half round head solid rivets;
d. Method, characteristics and application of plate riveting: First, the end face of the plate and one end of the channel steel or pressure forming part are lap assembled, and then connected together with rivets;
e. Method, characteristics and application of rivet riveting: lap a plate that has been punched through the hole on another plate that has been punched and turned over the edge of the hole, then flange the hole and press tightly;
And the use of rivet riveted in the hole side, mostly used for sealing structure, and the use of flat head semi-hollow rivet; Prevent rust corrosion caused by water leakage.
