Description

Technical Field

[0002] The riveting process is widely used in traditional manufacturing and traditional processing industries. When the workpieces are riveted together by rivets, there will be a certain gap between the workpieces after riveting. However, when the riveting processing devices of most workpieces are used, it is impossible to ensure that the gap value is fixed and parallel after riveting is completed. At the same time, some workpieces need to be connected together by four-step rivets, and a riveting machine is required to rivet eight times on the front and back sides. This method has low production efficiency and cannot guarantee the parallelism and gap between the workpieces. The riveting force value cannot be controlled, and overpressure leads to scrapping, with a high scrap rate.

[0003] Based on this, a tool capable of performing riveting at multiple stations simultaneously is now provided, which can eliminate the drawbacks of the existing devices. Utility Model Content
