Connection method of sheet metal stamping parts

There are sheet metal stamping parts in the stamping parts, and stamping parts have different production processes in the processing and production. What is the connection method of the cold work process of the common sheet metal stamping parts? The stamping parts processing manufacturers will give you a brief explanation; the connection methods of sheet metal stamping parts include: seam connection, riveting, welding, screw connection, pre-embedding (expansion), etc.; seam connection is to fold the edges of the stamping parts into each other The connection method of buckle and compression, the seam connection does not require special equipment, its compactness is good, and the connection is very reliable. It is often used for sheet metal institutions with a thickness of less than 1mm. For example, our common iron and copper connection is this connection method ; Riveting is a non-detachable connection formed by rivets. The riveted structure has the characteristics of uniform and reliable transmission, toughness, good plasticity, and easy maintenance, so it is used for the connection of some dissimilar metals and weldable metals (such as aluminum alloys). ), etc.; welding; when the sheet metal stamping parts cannot meet the expected requirements. Two parts are commonly connected into one part. This is what we often call welding. The most commonly used welding is argon arc welding, electric welding, gas welding, etc.; screw connections are generally used for detachable structures, which are characterized by simple structure, assembly and disassembly Convenient, low cost, widely used, etc.; embedded connection; is to press screws, studs or nuts into sheet metal stamping parts. Embedded studs generally do not cause any problems, because the studs are specially made. There is a groove above the hexagonal head of the stud. When the hexagonal head is pressed, the material on the board will squeeze into the groove and can be fixed by itself. The screws are different. The screws we select are generally not specially made and have no extrusion grooves. Therefore, when the screws are pressed in, there is no place for the extruded material. Due to the extrusion of the material, it is difficult to control the screw and the sheet metal plane. Verticality. Therefore, when installing other parts, it is often difficult to assemble. The longer the screw, the more difficult it is to control. At this time, it is better not to use the pre-embedded form, and it is better to connect directly with screws.
