[0029] Please see Figures 1 to 7 As shown, this preferred embodiment provides a metal ring pressing and riveting device for automotive motor coverings, used to fix a metal daughter ring 22 and a metal mother ring 23 onto the motor covering body 21. It includes a base 1, an upper template 2, and a lower template 3. The lower template 3 is fixed to the worktable surface of the base 1. The upper template 2 is suspended above the lower template 3 and guided by a vertical slide rail 4 for vertical sliding. A downward-facing booster cylinder 5 is provided at the top of the base 1, and the output rod of the booster cylinder 5 is fixedly connected to the upper surface of the upper template 2. The booster cylinder 5 can be a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc.

[0030] The lower template 3 is provided with a product support seat 6 for placing and positioning the motor cover body 21, and a lower riveting mold 7 is provided on the lower template 3 corresponding to the riveting position of the metal ring. The lower riveting mold 7 is used to place and position the metal sub-ring 22. Multiple locking feet 24 extend from the inner ring of the metal sub-ring 22, thereby effectively preventing the motor cover body 21 and the metal sub-ring 22 from moving and ensuring the riveting accuracy.

[0031] The upper template 2 is provided with an upper riveting core 8 corresponding to the lower riveting mold 7. A pre-pressing mold 9 is slidably sleeved on the upper riveting core 8. The pre-pressing mold 9 is used to press the metal female ring 23, which is placed on the motor cover body 21 and pre-fitted with the metal female ring 22. The upper riveting core 8 is used to press the locking foot 24 of the metal female ring 22, so that the locking foot 24 is expanded and further turned outward to complete the riveting.

[0032] Specifically, grooves 25 are formed on the end face of the metal mother ring 23 corresponding to each clamping foot 24. During riveting, the clamping foot 24 is turned outward and pressed into the groove 25. Positioning protrusions 10 are provided on the pre-pressing mold 9 corresponding to each groove 25 in order to accurately position the metal mother ring 23.

[0033] The end of the upper riveting die core 8 is provided with a protrusion 11 that can extend into the inner ring of the metal sub-ring 22. A tapered inclined surface 12 is formed on the protrusion 11, and a stop plane 13 is formed at the root of the tapered inclined surface 12. As the protrusion 11 gradually extends into the metal sub-ring 22, the tapered inclined surface 12 causes the locking foot 24 to expand, and the stop plane 13 causes the locking foot 24 to bend and turn outward.

[0034] A pin 14 is radially inserted into the upper riveting die core 8, and a stroke groove 15 is provided on the pre-pressing die 9 to allow the pin 14 to pass through, thereby limiting the relative displacement between the upper riveting die core 8 and the pre-pressing die 9. Furthermore, a limiting part 16 protrudes from the upper riveting die core 8, and a spring 17 is sleeved on the upper riveting die core 8 between the limiting part 16 and the pre-pressing die 9.

[0035] In addition, the upper template 2 is provided with a first adjusting plate 18, and the upper riveting die core 8 is installed on the first adjusting plate 18, so that the upper and lower positions of the upper riveting die core 8 are adjustable. The lower template 3 is provided with a second adjusting plate 19, and the lower riveting die 7 is installed on the second adjusting plate 19, so that the upper and lower positions of the lower riveting die 7 are adjustable, so as to adjust the relative positions of the upper riveting die core 8 and the lower riveting die 7 and ensure the positional accuracy of the product riveting.

[0036] The upper template 2 and the lower template 3 are respectively provided with mold closing guide pillars 20 to ensure that the mold pressing and riveting action is carried out accurately and to ensure the quality of pressing and riveting.

[0037] Production process flow:

[0038] (1) Embed the metal sub-ring 22 onto the lower pressing and riveting die 7, with its clamping feet 24 facing upwards;

[0039] (2) Place the motor cover body 21 on the product support base 6;

[0040] (3) Place the metal mother ring 23 onto the motor cover body 21 and position it corresponding to the metal daughter ring 22;

[0041] (4) Initially, the spring 17 is in a free state. Under the action of the spring 17, the pre-pressing mold 9 pushes out the upper pressing and riveting mold core 8, and starts the booster cylinder 5 to drive the upper template 2 to move downward, causing the pre-pressing mold 9 to press against the metal mother ring 23.

[0042] (5) The upper template 2 continues to descend, driving the upper riveting die core 8 to press down, so that the upper riveting die core 8 presses onto the clamping foot 24 of the metal sub-ring 22, and the clamping foot 24 is opened at a certain angle;

[0043] (6) The pressure cylinder 5 continues to increase the pressure, and the pressure increases instantly, causing the clamping foot 24 to be folded onto the surface of the metal ring 23, and the riveting is completed.

[0044] (7) The upper template 2 and the upper pressure riveting core 8 and the pre-pressing mold 9 on it retract to their original positions.

[0045] In summary, the aforementioned automotive motor cladding metal ring pressing and riveting equipment combines the processes of expanding and pressing the metal rings of the mother-daughter structure into one step, thereby improving production efficiency and ensuring product quality.
