With the development of modern industrial requirements, the future circuit board will be further to the direction of composite, functional development. As a result of growing environmental awareness, coated panels and lightweight materials such as aluminum alloy panels for automobiles are bound to become more widely used, which have been largely hampered by traditional spot welding processes. Therefore, how to solve the connection problem of these new plates by hardware stamping parts manufacturers is not only the key to the widespread use of these plates, but also crucial to the quality progress and cost reduction of modern industrial products.
Hardware stamping parts manufacturers commonly used stamping parts connection methods are:
- Bite connection: Bite connection is the connection method of folding and squeezing the edges of the sheet metal. Bite joint does not need special equipment, its density is good, the connection is very firm. Hardware stamping parts manufacturers
- Riveting: When sheet metal stamping parts can not meet the expected requirements. Two commonly used pieces into a piece, this is the metal stamping parts manufacturers often say welding, welding is the most commonly used argon arc welding, electric welding, gas welding, etc.; Riveting is composed of rivets can not open the connection mode, riveting structure has uniform force, good toughness, plasticity, easy to repair and other characteristics, so it is often used in some dissimilar metal connection and welding metal (such as aluminum alloy) connection;
- Thread connection: generally use detachable structure, its characteristics are simple structure, convenient installation and disassembly, low cost, widely used;
- Embedded connection: Press screws, studs or nuts into the sheet metal parts of the stamping parts. There is usually no problem with the inserts because the nails are specially made and there is a slot in the hexagonal head of the nails. When pressed into the hexagonal head, the material on the plate squeezes into the slot and holds it in place. The screws are different. The screw selected by hardware stamping parts manufacturers is generally not specially manufactured, and there is no extrusion groove. So when the screw presses into the metal, the extruded material has nowhere to go. Therefore, when installing additional parts, it is often difficult to install the situation, the longer the screw, the more difficult to control. At this time, do not choose the embedded form, directly with the screw connection is better.
