[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] The utility model provides a stamping die for a gear ring of an elastic coupling, comprising a support frame 1, an upper punch 2, a lower die 3, an upper die base 4 and a lower die base 5. The upper die base 4 and the lower die base 5 are arranged up and down and are slidably connected up and down. The bottom of the support frame 1 can be fixed on the workbench of a punching machine, the top surface of the support frame 1 is fixed with the lower die base 5, the top surface of the lower die base 5 is fixed with the lower die 3, and the bottom surface of the upper die base 4 is fixed with the upper punch 2. The support frame 1 is provided with a channel 11, and the channel 11 is for the formed part of the gear ring 80 to pass through.

[0029] The basic usage of this utility model:

[0030] S1: Fix the upper die base 4 on the slide of the punching machine;

[0031] S2: Fix the support frame 1 on the workbench of the punching machine;

[0032] S3: Fix the lower die base 5 on the support frame 1;

[0033] S3: Fix the upper punch 2 on the upper die base 4;

[0034] S4: Fix the lower die 3 on the lower die base 5;

[0035] S5: Then manually take the strip sheet 70 and place it on the upper surface of the lower die 3;

[0036] S6: Press the start switch of the punching machine, and the slider of the punching machine causes the lower die base 5 to descend, thereby causing the lower punch to descend until the upper punch 2 and the lower die 3 are closed. After the two are closed, a small section of the strip sheet material 70 is punched out; when the small section is punched out, manually push the strip sheet material 70 forward a small section, continue to hold the strip sheet material 70 in your hand, and continue to punch the next section until the strip sheet material 70 is punched into a toothed ring, and then weld the front end and the rear end.

[0037] Specifically, the upper punch 2 includes a first module 21 and a second module 22 arranged front to back along the X-axis direction. The bottom surface of the first module 21 is provided with a first convex portion 21a, and the bottom surface of the second module 22 is provided with a second convex portion 22a. The bottom surfaces of the first module 21 and the second module 22 are combined to form a first arc surface that is convex upward. The top surface of the lower die 3 is provided with a first groove 31 and a second groove 32 arranged front to back along the X-axis direction. The top surface of the lower die is a second arc surface that is convex upward. The first convex portion 21a fits with the first groove 31, the second convex portion 22a fits with the second groove 32, and the first arc surface fits with the second arc surface.

[0038] The specific steps of stamping are as follows:

[0039] S61: At the beginning of stamping, the front end of the strip sheet 70 is first placed on the upper surface of the second groove 32 for stamping and forming. At the same time, since there is no strip sheet 70 in the first groove 31, the first protrusion 21a is pressed empty.

[0040] S62: The formed part is moved to the upper surface of the first groove 31, and the rear part of the formed part is moved to the upper surface of the second groove 32. Then the first protrusion 21a is pressed into the first groove 31, thereby pressing the formed part for positioning, making it convenient to stamp the rear part of the formed part; then the second protrusion 22a is pressed into the second groove 32 to stamp the rear part.

[0041] S63: Repeat the steps of S62.

[0042] The present invention also includes a first pressing plate 6 and a second pressing plate 7. The second pressing plate 7 is fixed on the bottom surface of the upper mold base 4. The second pressing plate 7 is slidably connected above the first pressing plate 6. A gap is provided between the second pressing plate 7 and the first pressing plate 6. A second module 22 is fixed on the bottom surface of the second pressing plate 7. The first pressing plate 6 is provided with a through hole 61 for the second module 22 to pass through. A first module 21 is fixed on the bottom surface of the first pressing plate 6. After the lower mold base 5 drops to the limit (according to the pre-set stroke), the second pressing plate 7 just slides to the top surface of the first pressing plate 6, and the second pressing plate 7 contacts the first pressing plate 6. Since the initial spacing between the first groove 31 and the first convex portion 21a is S1, and the initial spacing between the second groove 32 and the second convex portion 22a is S2, S1<S2, so when the second pressing plate 7 contacts the first pressing plate 6, the time when the first convex portion 21a matches the first groove 31 is earlier than the time when the second convex portion 22a matches the second groove 32.

[0043] A guide sleeve 8 is provided at the corner of the bottom surface of the upper mold base 4, and a guide column 9 is provided at the corner of the top surface of the lower mold base 5. The top of each guide column 9 is inserted into the guide sleeve 8 at the corresponding position. The mutual cooperation between the guide column 9 and the guide sleeve 8 reduces the time and cost of mold adjustment. The above structure provides precise guidance for the movement of the upper mold base 4 and enables the upper mold base 4 to descend stably. At the same time, it also reduces the scrap rate caused by inaccurate molds, thereby improving production efficiency and product quality.

[0044] In order to ensure that the lower die can be accurately aligned with the upper die when installing the utility model, and to avoid the misalignment of the lower die and the upper die, which may lead to poor quality of the stamped product or even directly become waste, the utility model is further provided with a lower die matching and fixing assembly 10, which includes a lower die fixing plate 101, a clamping pad 102, and a hexagon socket head bolt 103. The left and right ends of the lower die fixing plate 101 are respectively provided with slots 101a, and the top surface of the lower die base 5 is provided with a threaded blind hole. The lower die fixing plate 101 is provided with a threaded blind hole. Placed on the top surface of the lower die base 5, a clamping pad 102 is provided on the top of the slot 101a, and the clamping pad 102 is provided with a waist-shaped hole whose length extends along the Y-axis direction. The hexagonal cylindrical head bolt 103 can be inserted into the waist-shaped hole, the slot 101a and the threaded blind hole in sequence. The bottom of the hexagonal cylindrical head bolt 103 is threadedly connected in the threaded blind hole. The diameter of the head of the hexagonal cylindrical head bolt 103 is larger than the diameter of the waist-shaped hole, and the width and length of the slot 101a are both larger than the diameter of the rod of the hexagonal cylindrical head bolt 103.

[0045] In step S4, first pre-fix the lower die 3 on the lower die base 5 (thread the hexagon socket head bolt 103 in the threaded blind hole, but the head of the hexagon socket head bolt 103 is detached from the top of the clamping pad). At this time, the lower die fixing plate 101 can move within a certain range relative to the lower die base 5. Then manually lower the upper punch 2 that has been installed on the slider to a position close to the lower die 3. Adjust the position of the lower die fixing base according to the position of the upper punch 2 so that the upper punch 2 and the lower die 3 can be aligned. After the upper punch 2 and the lower die 3 are closed, continue to rotate the hexagon socket head bolt 103 into the threaded blind hole until the head of the hexagon socket head bolt 103 is clamped on the upper surface of the clamping pad. At this time, fix the lower die fixing plate 101 on the lower die base 5, that is, fix the lower die 3 on the lower die base 5.

[0046] The present invention also includes an upper die pressing guide mechanism, which includes a first guide plate 201 and a second guide plate 202. The first guide plate 201 and the second guide plate 202 are respectively fixed to the left and right side surfaces of the lower die, and the tops of the first guide plate 201 and the second guide plate 202 are partially higher than the top of the lower die. During stamping, when the upper punch 2 is driven down by the slider, before it is about to close with the lower die 3, the two sides of the upper punch 2 respectively contact the first guide plate 201 and the second guide plate 202. The first guide plate 201 and the second guide plate 202 provide a guiding function for the upper punch 2, so that the upper punch 2 will not deviate along the Y-axis direction during the descent process, ensuring that the upper punch 2 can be accurately aligned with the lower die 3.

[0047] The present invention further includes a feed guide mechanism 30 and a discharge guide mechanism 40. The feed guide mechanism 30 is fixed to the rear side of both the first guide plate 201 and the second guide plate 202, while the discharge guide mechanism 40 is fixed to the front side of both the first guide plate 201 and the second guide plate 202. The feed guide mechanism 30 provides guidance for the strip material 70 to move forward upon entering the mold, while the discharge guide mechanism 40 provides guidance for the formed portion to exit the mold.

[0048] A cushioning rubber pad 50 is fixed to the top surface of the upper die holder 4, while a supporting balancing column 60 is fixed to the top surface of the lower die holder 5. The supporting balancing column 60 is made of rubber and is spaced apart from the lower die 3 along the Y-axis. When the upper punch 2 and the lower die 3 are fully closed, the bottom surface of the upper die holder 4 also contacts the top surface of the supporting balancing column 60. The interaction between the upper die holder 4 and the supporting balancing column 60 provides additional balancing support for the upper punch 2 and the lower die 3, ensuring a more stable closing during the stamping process.

[0049] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
