[0002] Riveting refers to the process of connecting two or more parts together using rivets. Riveting dies typically include components such as an upper die base, punch, guide post, lower die base, and die cavity. A rivet is a metal part with a pre-formed head at one end and a smooth shank at the other. In riveting, holes are drilled in the parts to be connected, the rivet is passed through the holes, and then the parts are secured by pressing or deforming the rivet.

[0003] The rivet molds currently used can achieve efficient and precise rivet forming, stably control the error of the rivet head within a certain range, firmly connect the rivet to the component, meet the basic strength requirements, work stably with manual assistance, and support mass production.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-5This utility model provides an embodiment of a riveting forming mold, wherein a lower mold base 2 is fixedly connected to the center of the top of the base 1, and rotating shafts 3 are rotatably connected to both the left and right sides inside the lower mold base 2. Multiple evenly distributed concave molds 4 are fixedly connected to the outer periphery of the rotating shafts 3. A fixing component is provided on the right side of the lower mold base 2. Rotating the rotating shafts 3 causes the concave molds 4 to rotate together. A fixing component is provided on the right side of the lower mold base 2.

[0035] The fixing assembly includes a base 20, which is fixedly connected to the right side of the lower mold base 2. A spring mounting groove 6 is provided in the middle of the inner side of the base 20. Fixed rods 8 are slidably connected to both ends of the base 20. A lever 7 is fixedly connected to the bottom of the fixed rod 8. A second spring 23 is slidably connected inside the base 20. The sliding lever 7 drives the fixed rod 8 to extend and retract by squeezing the second spring 23. The fixed rod 8 is aligned with the fixed hole 19 so that the fixed rod 8 can slide in and out of the fixed hole 19 to fix the rotating shaft 3 and the die 4. The second spring 23 is slidably connected in the spring mounting groove 6 to ensure that the second spring 23 can work stably in the spring mounting groove 6.

[0036] Reference Figure 1 and Figure 2 The rivet forming mold is characterized in that: both ends of the rotating shaft 3 are fixedly connected to locking blocks 5, the locking blocks 5 have a fixing hole 19 in the middle, the top center of the base 1 has an inclined groove 16, the bottom end of the base 1 has a collection groove 17, and the lower mold base 2 has multiple evenly distributed rotating grooves 15 inside. The fixed component, under the rotation of the rotating shaft 3, falls through the rotating groove 15 into the inclined groove 16, and then slides down from the inclined groove 16 into the collection groove 17, facilitating collection by workers.

[0037] Reference Figures 1-3 The base 1 has a shock-absorbing lower rod 9 abutting at its top. A shock-absorbing pile 24 is fixedly connected to the top of the shock-absorbing lower rod 9. A shock-absorbing upper rod 10 is abutting at the top of the shock-absorbing pile 24. A top plate 11 is fixedly connected to the top of the shock-absorbing upper rod 10. A spring 18 is sleeved on the outer periphery of the shock-absorbing lower rod 9 for buffering and shock absorption. An upper mold base 13 is fixedly connected to the middle of the bottom side of the top plate 11. Multiple evenly distributed punches 14 are fixedly connected inside the upper mold base 13. The punches 14 are aligned with the die 4 and complete the rivet stamping by moving up and down. A paddle sliding groove 22 is opened on the right side of the base 20. The paddle 7 is slidably connected in the paddle sliding groove 22.

[0038] Reference Figure 1 and Figure 4An engine 12 is fixedly connected to the top of the top plate 11, and an engine connecting rod 21 is fixedly connected to the bottom output end of the engine 12. The bottom end of the engine connecting rod 21 is fixedly connected to the top of the top plate 11. The engine 12 drives the top plate 11 to move downward, which in turn drives the punch 14 of the upper mold base 13 to move downward, cooperate with the die 4 of the lower mold base 2, and complete the riveting of the parts.

[0039] Working principle: When the riveting forming die is working, the sliding paddle 7 first drives the fixed rod 8 to extend and retract. The paddle 7 slides within the paddle sliding groove 22, compressing the spring 23, which disengages the fixed rod 8 from the fixing hole 19 of the latch block 5, releasing the fixation on the rotating shaft 3. When the rotating shaft 3 is rotated, the multiple dies 4 on its outer periphery rotate together. After the target die 4 is aligned with the punch 14, the paddle 7 is released, the spring 23 returns to its original position, and pushes the fixed rod 8 into the corresponding fixing hole 19, firmly fixing the rotating shaft 3 and the die 4, ensuring stability during stamping.

[0040] During the stamping process, the engine 12 drives the top plate 11 to move downwards, causing the punch 14 of the upper die holder 13 to move downwards and cooperate with the die 4 of the lower die holder 2 to complete the rivet forming. The spring 18, the lower shock absorber rod 9, the shock absorber pile 24, and the upper shock absorber rod 10 in the shock absorption structure work together to buffer the impact force during stamping. The formed part falls into the inclined groove 16 through the rotating groove 15, and then slides into the collection groove 17, which is convenient for workers to collect. The whole process is efficient and stable.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
