[0014] Preferably, a roller is rotatably provided at the end of the abutment groove, and the roller can roll on the inclined sliding surface or the side wall of the inclined wedge.
[0015] By adopting the above technical solution, when the inclined wedge is inserted into the abutment groove, the roller rolls on the inclined sliding surface or the side wall of the inclined wedge, thereby reducing the friction between the inclined wedge and the side wall of the abutment groove.

DETAILED DESCRIPTION
[0031] The following is combined with Figure 1-4 This application is described in further detail.
[0032] The present application embodiment discloses a rivet and spring riveting forming mechanism. Figure 1 It includes a lower pressing block 1 fixedly connected to the lower die seat of the continuous die, and an upper pressing block 2 fixedly connected to the upper die seat of the continuous die. When the upper die seat and the lower die seat of the continuous die press the spring sheet material strip, they make continuous relative vertical sliding motion, and at the same time, the spring sheet material strip makes horizontal stepping motion under the action of the continuous die and enters between the lower pressing block 1 and the upper pressing block 2.
[0033] Reference Figures 2 to 4 A discharge block 11 is fixedly mounted on the lower pressing block 1, and a discharge hole 111 is provided on the discharge block 11. A guide rail for guiding the rivet to enter is connected to the discharge hole 111. A slider 12 is slidably arranged in the lower pressing block 1, and a rivet nail groove 121 is provided on the slider 12. The rivet nail groove 121 can be directly opposite to the discharge hole 111. A sliding assembly 13 for driving the slider 12 to slide is arranged between the lower pressing block 1 and the upper pressing block 2. The guide rail guides the rivet into the discharge hole 111, and the bottom of the rivet contacts the slider 12. The slider 12 slides under the action of the sliding assembly 13. When the rivet nail groove 121 is not directly opposite to the discharge hole 111, the rivet is restricted in the rivet groove. After the rivet nail groove 121 is opposite to the discharge hole 111, the rivet in the discharge hole 111 naturally falls into the rivet nail groove 121 under the action of gravity.
[0034] Reference Figures 2 to 4 A group of floating material grooves 14 are provided on both sides of the lower pressing block 1. A floating material block 141 is provided in the floating material groove 14 for sliding movement. A floating material spring 142 is provided between the floating material block 141 and the bottom wall of the floating material groove 14. The floating material spring 142 drives the floating material block 141 away from the bottom wall of the floating material groove 14. A pressing block 21 is fixedly provided on the upper pressing block 2. A riveting punch 211 is provided in the pressing block 21. A positioning pin 22 is fixedly provided on the upper pressing block 2. The positioning pin 22 can be abutted against the floating material block 141. The floating material spring 142 drives the floating material block 141 to lift the spring sheet material belt. During the sliding process of the slider 12, the slider 12 drives the rivet to slide from under the spring sheet material belt, so that the riveting nail groove 121 is opposite to the riveting punch 211.
[0035] Reference Figures 2 to 4 In the process of the upper pressing block 2 pressing down the lower pressing block 1, the positioning pin 22 first passes through the positioning hole pre-opened on the spring sheet material strip to position the spring sheet material strip. Then the spring sheet material strip is pressed down by the pressing block 21, and at the same time, the positioning pin 22 presses down the floating block 141, so that the rivet passes through the rivet hole pre-opened on the spring sheet material strip. Then, the rivet is squeezed and riveted to the spring sheet material strip under the action of the end of the riveting punch 211. After the upper pressing block 2 is lifted up, the floating block 141 lifts up the spring sheet material strip again, and the rivet is disengaged from the riveting nail groove 121. When the spring sheet material strip is processed by continuous die pressing, rivet points are simultaneously riveted on the spring sheet material strip, which reduces the material turnover time and improves work efficiency.
[0036] In order to facilitate the sliding block 12 to slide on the groove plate, refer to Figure 3 and Figure 4The sliding assembly 13 includes an inclined wedge 23, a fixed seat 131, a force transmission pin 133, and a return spring 134. The fixed seat 131 is fixedly arranged on the lower pressing block 1, and a sliding groove 132 is provided in the fixed seat 131. The force transmission pin 133 is slidingly arranged in the sliding groove 132, and the end of the force transmission pin 133 is fixedly connected to the slider 12. One end of the return spring 134 is fixedly connected to the force transmission pin 133, and the other end of the return spring 134 is fixedly connected to the bottom wall of the sliding groove 132. The return spring 134 drives the force transmission pin 133 away from the bottom wall of the sliding groove 132. When the inclined wedge 23 is separated from the abutting groove 122, the return spring 134 drives the force transmission pin 133 away from the bottom wall of the sliding groove 132, and the force transmission pin 133 pushes the slider 12 to slide, and the rivet nail groove 121 is opposite to the discharge hole 111.
[0037] Reference Figure 3 and Figure 4 The slider 12 is provided with an abutment groove 122, and a roller 1221 is rotatably provided at the end of the abutment groove 122. The inclined wedge 23 is provided with an inclined sliding surface 231, and the inclined wedge 23 can be inserted into the abutment groove 122, and the roller 1221 can roll on the inclined sliding surface 231 or the side wall of the inclined wedge 23. When the upper pressing block 2 presses the lower pressing block 1 downward, the inclined wedge 23 is inserted into the abutment groove 122, and the inclined sliding surface 231 of the inclined wedge 23 abuts and slides against the abutment groove 122, and the slider 12 slides under the action of the abutment groove 122 and the inclined wedge 23. When the inclined wedge 23 is fully inserted into the abutment groove 122, the rivet nail groove 121 is opposite to the rivet punch 211. Thereby, the slider 12 is driven to slide on the groove plate.
[0038] In order to adjust the riveting force of the rivet on the spring strip, refer to Figure 3 , the riveting punch 211 is slidably arranged in the pressing block 21, and an angled pad 2111 is fixedly arranged at the end of the riveting punch 211. An adjusting rod 24 is slidably arranged on the upper pressing block 2, and an angled inclined surface 241 is provided at one end of the adjusting rod 24, and the angled inclined surface 241 can abut against the angled pad 2111. An adjusting block 242 is fixedly arranged at the other end of the adjusting rod 24, and an adjusting bolt 243 is rotatably arranged on the adjusting block 242, and the adjusting bolt 243 is threadedly engaged with the side wall of the upper pressing block 2. A tightening spring 252 is arranged in the upper pressing block 2, and the tightening spring 252 drives the angled pad 2111 to keep against the adjusting rod 24. The adjusting bolt 243 is rotated to drive the adjusting rod 24 to slide, and the angled inclined surface 241 of the adjusting rod 24 abuts and slides against the top inclined surface of the angled pad 2111. In this way, the length of the riveting punch exposed from the pressing block 21 is finely adjusted, thereby changing the degree to which the rivet is squeezed by the riveting punch, thereby adjusting the riveting force of the rivet on the spring sheet material strip.
[0039] The implementation principle of a rivet and spring sheet riveting forming mechanism in an embodiment of the present application is as follows: the upper die seat and the lower die seat of the continuous die slide continuously relative to each other, and the spring sheet material strip is pressed and formed by the die in the continuous die. At the same time, the spring sheet material strip performs stepping motion under the action of the continuous die and enters between the lower pressing block 1 and the upper pressing block 2. When the upper die seat is lifted, the inclined wedge 23 disengages from the abutment groove 122, and the return spring 134 drives the force transmission pin 133 to push the slider 12 to slide, and the rivet nail groove 121 is opposite to the discharge hole 111. The guide rail guides the rivet into the discharge hole 111, and the rivet naturally falls into the rivet nail groove 121 under the action of gravity. The floating material spring 142 drives the floating material block 141 to lift the spring sheet material strip. During the process of the upper die seat of the continuous die pressing down on the lower die seat, the inclined wedge 23 is inserted into the abutment groove 122, and the inclined sliding surface 231 of the inclined wedge 23 abuts and slides against the abutment groove 122, and the slider 12 slides under the action of the abutment groove 122 and the inclined wedge 23. Until the side wall of the inclined wedge 23 begins to abut against the roller 1221, the rivet groove 121 is opposite to the riveting punch 211. Then the roller 1221 rolls against the side wall of the inclined wedge 23, and the positioning pin 22 first passes through the positioning hole pre-opened on the spring sheet material strip to position the spring sheet material strip. Then the spring sheet material strip is pressed down by the pressing block 21, and at the same time, the positioning pin 22 presses down the floating block 141, so that the rivet passes through the rivet hole pre-opened on the spring sheet material strip. Then, under the action of the end of the riveting punch 211, the rivet is squeezed and riveted to the spring sheet material strip. After the upper pressing block 2 is lifted, the floating material block 141 lifts the spring sheet material belt, and the rivet is separated from the riveting nail groove 121. When the spring sheet material belt is continuously pressed and processed, the rivet points are simultaneously riveted on the spring sheet material belt, which reduces the material turnover time and improves the work efficiency.
[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
