Description

Technical Field

[0001] This utility model relates to the field of stamping and riveting connection technology, and specifically to a base plate assembly for stamping and riveting connection. Background Technology

[0002] Riveting, as a highly efficient mechanical connection technology, demonstrates significant advantages in the manufacturing of base plate assemblies and related components, playing a crucial role, especially in automotive lightweighting and electronic component assembly. Its core principle is to achieve thin-plate connection through the interlocking structure of rivets and the base plate, featuring strong process adaptability and stable connection strength.

[0003] Instruction manual attached Figure 1 The system includes a base plate body 1 and a cable fixing plate 2, which are welded together to form a whole. The cable fixing plate 2 is made of hot-rolled steel plate with a thickness of 4.5mm and is stamped on a press using a special stamping die. The base plate body 1 is made of ordinary cold-rolled steel plate with a thickness of 2.5mm and is also manufactured by a corresponding stamping process. After the base plate body 1 and the cable fixing plate 2 are placed in a special welding fixture, they are welded together using CO2 shielded welding to combine the two parts into a whole.
