[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figures 1-4 This utility model provides an embodiment of a hexagonal nut riveting spring device, comprising: a pressing column 1, a bending positioning seat 2 at one end of the pressing column 1, a pressing seat 3 at the upper end of the bending positioning seat 2, a bending seat 8 opposite the bending positioning seat 2, a spring plate 10 between the bending seat 8 and the bending positioning seat 2, an open pushing seat 9 on one side of the bending seat 8, a separating seat 7 on the other side of the bending seat 8, the separating seat 7 having a T-shaped structure, a moving guide seat 6 below the separating seat 7, a bending seat 4 opposite the moving guide seat 6, a limiting seat 5 at the upper end of the bending seat 4, a bending inclined surface 15 on the upper surface of the bending seat 4, a bending limiting groove 14 on the lower surface of the limiting seat 5, and a connecting inclined surface 16 on one side of the lower surface of the bending seat 4. One end surface of seat 6 is provided with a guide slope 12, and the connecting slope 16 moves along the guide slope 12. One end surface of bending seat 8 is provided with a bending concave angle 13, and the corner edge of the bending concave angle 13 is arc-shaped. The inner bottom surface of the opening push seat 9 is provided with an arc-shaped protruding rib 11, and the arc-shaped protruding rib 11 and the opening push seat 9 are an integral structure. The arc-shaped protruding rib 11 is semi-circular arc-shaped, and the opening push seat 9 has a U-shaped structure with a flat bottom. The pressing column 1 drives the bending positioning seat 2 to press one side of the spring plate 10, and then the opening push seat 9 presses the spring plate 10. The opening push seat 9 has a U-shaped structure with a flat bottom, and the inner bottom surface of the opening push seat 9 has an arc-shaped protruding rib 11. When the spring plate 10 is stamped, strip-shaped and arc-shaped openings will appear, as shown in the attached figure. Figure 3As shown, the opening push seat 9 moves to the initial position, and then the spring plate 10 is pressed out of the opening position by the opening push seat 9 and moved to the bending seat 8 position. The bending seat 8 squeezes the spring plate 10. When squeezing, the spring plate 10 is driven to bend along the opening. The bending angle is limited by the bending positioning seat 2. Then the spring plate 10 continues to move and moves between the bending seat 4 and the moving guide seat 6. The limiting seat 5 squeezes and limits the spring plate 10. Then the squeezing seat 3, bending seat 4 and moving guide seat 6 move towards the spring plate 10. Since the connecting inclined surface 16 moves along the guiding inclined surface 12, the squeezing seat 3 moves along the connecting strip 18 through the connecting groove 17, so that the bending seat 4 moves upward and is inserted into the bending limiting groove 14 of the limiting seat 5. When inserted, the bent spring plate is driven to bend upward, so as to further bend and form. Finally, the separating seat 7 punches the spring plate 10 and punches and separates the bent part, thus realizing the spring plate forming.
