In the field of sheet metal processing, the stamping riveting process, as a common method of connection, is widely used in industries such as electronics, communication, automotive, and aviation. Its main feature is to embed the rivet into the sheet metal parts through pressure, achieving a firm connection. However, due to the diversity of sheet metal materials and the differences in thickness and strength, how to accurately control the force during the stamping riveting process has become a key factor to ensure product quality.



Firstly, understanding the basic principle of the stamping riveting process is the premise of controlling force. Stamping riveting is achieved by applying pressure to the rivet through molds or special equipment, causing it to deform and embed into the sheet metal holes, forming a reliable connection. If the pressure is too high, it may cause deformation, cracking of the sheet metal, or even damage to the equipment; insufficient pressure will result in the rivet not being fully embedded, resulting in a loose connection and affecting the structural strength.



Secondly, the key to controlling force lies in the selection of appropriate equipment and parameter setting. Currently, commonly used stamping riveting machines include pneumatic, hydraulic, and servo-driven types. Among them, servo stamping riveting machines have the advantage of dual closed-loop control of pressure and displacement, which is more advantageous in terms of accuracy and stability. By setting reasonable pressure values and combining displacement feedback for real-time adjustment, over-pressure or under-pressure phenomena can be effectively avoided.



Moreover, the optimization of process parameters is crucial for force control. This includes rivet material, size, sheet metal thickness and hardness, etc. Before actual operation, a trial stamping riveting experiment should be carried out according to product requirements, and the optimal pressure range should be determined through testing the connection strength and appearance quality. At the same time, regular detection of die wear should be ensured to ensure uniform force during the stamping riveting process.



In addition, the introduction of automation and intelligent control systems is an important means to improve the accuracy of force control. Modern stamping riveting equipment is often equipped with PLC control systems and pressure sensors, which can monitor all parameters in the stamping riveting process in real time, and optimize the process flow through data analysis to improve product consistency and pass rate.



In summary, the control of force in the stamping riveting process is a systematic project, which requires comprehensive consideration from multiple aspects such as equipment selection, parameter setting, process optimization, and automation control. Only on the basis of scientific management and precise operation can the quality of stamping riveting be effectively improved to meet the increasingly growing demand for high-precision and high-strength connections in modern manufacturing industry.
