Description

Technical Field

[0001] This utility model relates to the field of wire spring pin technology, and in particular to a wire spring pin interference fit riveting mechanism. Background Technology

[0002] Currently, the interference fit of the front and rear sleeve pins of the spring wire is mostly produced using automated assembly machines. On the one hand, automated machines lack compatibility. They are typically designed for specific products or production processes and are relatively poorly adaptable to product changes or diversified production. Adjusting the specifications, models, or assembly methods of the spring wire may require significant equipment modifications, leading to production interruptions and increased costs. On the other hand, automated equipment has high requirements for spring wire quality. If the spring wire has dimensional deviations, irregular shapes, or other quality problems, it can cause equipment malfunctions or unstable product quality. A failure in the automated assembly machine can halt the entire production process, impacting efficiency. Furthermore, the initial deployment of automated assembly machines requires extensive debugging and optimization to ensure normal operation and stable product quality. This process consumes considerable time and resources, and subsequent operation also requires professional technicians for debugging and maintenance, increasing the cost and difficulty of technical support and training.
