[0030] To fully describe the technical content, structural features, objectives, and beneficial effects of this utility model, a detailed description will be provided below in conjunction with the accompanying drawings.

[0031] This utility model discloses an automatic production device for double-ear snap rings, such as... Figures 1 to 5 As shown, it includes a frame 1, a first platform 4, a second platform 5, a mold assembly, and a flexible winding assembly.

[0032] The front and rear walls of the frame 1 are connected by a fixed shaft 14. The front wall consists of two parts connected by a first connecting plate 30, which has a horizontally arranged first sliding groove 2. A vertically arranged second sliding groove 3 is provided on both the front wall on the first side and the corresponding rear wall.

[0033] In a preferred embodiment of this invention, two second sliding grooves 3 are provided at the same height and correspondingly positioned on the front and rear wall panels. A third drive shaft 12 is disposed within the second sliding groove 3, passing through the second sliding grooves 3 on both the front and rear wall panels. Both ends of the third drive shaft 12 are axially fixed by fixing bolts, meaning the axial positions of both ends of the third drive shaft 12 are fixed, preventing axial movement and allowing it to slide up and down along the second sliding groove 3 and rotate within it. A bushing is provided at the mating point between the third drive shaft 12 and the inner wall of the second sliding groove 3.

[0034] A first spring 13 is provided between the third drive shaft 12 and the fixed shaft 14. The function of the second slide groove 3 is to ensure that the third drive shaft 12 can reciprocate, and the function of the first spring 13 is to enable the third drive shaft 12 to return within the second slide groove 3. A bushing is provided at the connection between the first spring 13 and the third drive shaft 12. The purpose of the bushing is to reduce sliding friction when the third drive shaft 12 rotates and reciprocates, and also to improve its load-bearing capacity.

[0035] A first platform 4 is positioned above the second slide groove 3 on the front wall panel. A cam drive motor 29 is mounted on the first platform 4. The output end of the cam drive motor 29 is connected to the first end of the second transmission shaft 6. The second end of the second transmission shaft 6 passes through the front wall panel via a rolling bearing and is connected to the planar cam 7. In a specific embodiment of this invention, the outer circumference of the planar cam 7 is set as a plane, and the edge of the planar cam 7 is set as an irregular circular structure with different distances between its edge and the center point. The difference between the longest and shortest distances between the edge and the center point is equal to the length of the first slide groove 2. The cam drive motor 29 drives the second transmission shaft 6 to rotate, and the second transmission shaft 6 drives the planar cam 7 to rotate synchronously.

[0036] The second platform 5 is located above the second slide groove 3 on the rear wall panel. A mold drive motor 8 is installed on the second platform 5. The output end of the mold drive motor 8 is connected to the first transmission shaft 9, and the mold drive motor 8 drives the first transmission shaft 9 to rotate. The positions of the first transmission shaft 9, the mold drive shaft 11, and the third transmission shaft 12 are arranged in a triangular structure. A transmission timing belt 10 is provided on the first transmission shaft 9, the mold drive shaft 11, and the third transmission shaft 12. The transmission timing belt 10 is close to the outer circumference of the first transmission shaft 9, the mold drive shaft 11, and the third transmission shaft 12 and is in a closed loop. The first transmission shaft 9 is the main transmission shaft, which can drive the third transmission shaft 12 and the mold drive shaft 11 to rotate synchronously through the transmission timing belt 10.

[0037] The mold assembly includes a mold drive shaft 11 and a V-shaped bracket 16. The mold drive shaft 11 is disposed in the first slide groove 2 and is in contact with the planar cam 7. The planar cam 7 pushes the mold drive shaft 11 to reciprocate along the first slide groove 2. A second spring 15 is disposed between the first end of the mold drive shaft 11 and the first transmission shaft 9. The second spring 15 is arranged laterally and its function is to cause the mold drive shaft 11 to return in the first slide groove 2.

[0038] Bearings are provided at the contact points between the mold drive shaft 11 and the first slide groove 2, at the connection points between the mold drive shaft 11 and the second spring 15, and at the connection points between the second spring 15 and the first transmission shaft 9. The load distribution of the bearings is relatively uniform, which better reduces friction and wear when the mold drive shaft 11 and the first transmission shaft 9 rotate at low speed, thereby increasing their service life.

[0039] The second end of the mold drive shaft 11 is connected to the first side of the middle end of the V-shaped frame 16, and the second side of the middle end of the V-shaped frame 16 is connected to the second winding post 18. Wire fixing holes 20 are provided on both sides of the first end of the V-shaped frame 16, and a first winding post 17 is connected to the first end of the V-shaped frame 16. A third winding post 19 is connected to the second end of the V-shaped frame 16.

[0040] In a preferred embodiment of this utility model, the size of the V-shaped bracket 16 can be set according to the required specifications of the retaining spring. The V-shaped bracket 16 is detachably connected to the mold drive shaft 11, the first winding post 17, the second winding post 18, and the third winding post 19, and the V-shaped bracket 16 can be replaced according to the requirements of different specifications of retaining springs. The cross-sections of the first winding post 17, the second winding post 18, and the third winding post 19 are arranged horizontally in a V-shape and are parallel to each other, and are consistent with the structure of the matching V-shaped bracket 16.

[0041] The flexible winding assembly includes a first fixing post 21, a second fixing post 22, a second connecting plate 23, a third spring fixing shaft 24, a fourth spring fixing shaft 25, a third spring 26, a fourth spring 27, and a perforated plate 28. The first ends of the first fixing post 22 and the second fixing post 23 are connected to the upper and lower ends of the first connecting plate 30, respectively, and the second ends of the first fixing post 22 and the second fixing post 23 are connected through the second connecting plate 23. The first ends of the third spring fixing shaft 24 and the fourth spring fixing shaft 25 are both connected to the second connecting plate 23. Specifically, the third spring fixing shaft 24 and the fourth spring fixing shaft 25 are fixed to the second connecting plate 23 by bolts. The third spring 26 is mounted on the third spring fixing shaft 24, and the fourth spring 27 is mounted on the fourth spring fixing shaft 25. The second ends of the third spring fixing shaft 24 and the fourth spring fixing shaft 25 are both connected to the perforated plate 28, which has a wire-passing hole 281.

[0042] The perforated plate 28 is arranged adjacent to the V-shaped frame 16, and the distance between the perforated plate 28 and the first connecting plate 30 is greater than the thickness of the V-shaped frame 16. In a specific embodiment of this utility model, the V-shaped frame 16 drives the first winding post 17, the second winding post 18, and the third winding post 19 to rotate along the edge of the perforated plate 28. The first side of the V-shaped frame 16 is close to the first connecting plate 30, and the second side of the V-shaped frame 16 maintains a certain distance from the end of the perforated plate 28. When the V-shaped frame 16 rotates across the flexible winding assembly, collision between the V-shaped frame 16 and the perforated plate 28 is avoided.

[0043] The specific embodiments of this utility model are further described below:

[0044] Taking the production of double-eared retaining rings using 1mm diameter iron wire as an example, Figure 6 shows the corresponding positions of the mold rotation during the production process of this utility model:

[0045] In this invention, the cam drive motor and the mold drive motor cooperate with each other during the production process, moving alternately according to a preset program. The cam drive motor 29 drives the planar cam 7 to push the mold drive shaft 11 to reciprocate within the first slide groove 2. The mold drive shaft 11 returns to its starting position within the first slide groove 2 via the second spring 15. The mold drive motor 8 drives the V-shaped frame 16 to rotate via the transmission timing belt 10. During the rotation of the V-shaped frame 16, the third transmission shaft 12 returns to its starting position within the second slide groove 3 via the first spring 13. Since the length of the transmission timing belt 10 remains constant, the position of the first transmission shaft 9 remains stationary. When the position of the mold drive shaft 11 changes, the position of the third transmission shaft 12 changes synchronously to ensure the transmission of force by the mold drive motor 8. The rotation of the V-shaped frame 16 is always centered on the second winding post 18. That is, when the first winding post 17 and the third winding post 19 reciprocate within the first slide groove 2, they rotate around the second winding post 18 at different nodes.

[0046] The process of producing double-eared snap rings begins by first fixing the end of the wire through the threading hole 281 to the wire fixing hole 20 on the first winding post 17, thus fixing the starting part of the wire to the first winding post 17. Then, the mold drive motor 8 and the cam drive motor 29 are started. The steps are as follows:

[0047] S1. The mold drive motor 8 actuates, causing the mold drive shaft 11 to rotate clockwise. The wire abuts against the outside of the second winding post 18. The first winding post 17 and the second winding post 18 are in a horizontal state, and the third winding post 19 is located above. At this time, the V-shaped frame 16 is in its initial state, and the mold drive shaft 11 stops rotating. Figure 6a As shown.

[0048] S2, the cam drive motor 29 actuates, causing the planar cam 7 to rotate, pushing the mold drive shaft 11 to slide to the right within the first slide groove 2 until the perforated plate 28 passes between the second winding post 18 and the third winding post 19. The planar cam 7 then stops rotating, causing the wire to wind around and avoid the third winding post 19. Figure 6b As shown, at this time, the edge part that is furthest from the center point of the planar cam 7 contacts the mold drive shaft 11, which pushes the mold drive shaft 11 to the rightmost side of the first slide groove 2.

[0049] S3. Rotate the mold drive shaft 11 clockwise again, so that the first winding post 17 wraps around the perforated plate 28 once, and the wire is just wrapped around the second winding post 18 once. The mold drive shaft 11 then stops rotating. Figure 6c As shown.

[0050] S4. The planar cam 7 rotates again, causing the mold drive shaft 11 to slide to the leftmost side of the first slide groove 2. The planar cam 7 then stops rotating. Figure 6d As shown, at this time, the edge shortest from the center point of the planar cam 7 contacts the mold drive shaft 11, and the mold drive shaft 11 automatically returns to the leftmost side of the first slide groove 2 by the action of the second spring 15.

[0051] S5. Rotate the mold drive shaft 11 clockwise again to wind the wire onto the third winding post 19. The rotation angle should be such that the first winding post 17 is above the first slide groove 2, and the third winding post 19 is below the first slide groove 2. The mold drive shaft 11 should then stop rotating. Figure 6e As shown.

[0052] S6, the planar cam 7 rotates again, pushing the mold drive shaft 11 to the far right in the first slide groove 2. This action causes the wire to avoid winding around the second winding post 18. Figure 6f As shown.

[0053] S7. Rotate the mold drive shaft 11 clockwise again to make the wire wind around the first winding post 17 once more. Figure 6g As shown.

[0054] S8, the planar cam 7 rotates again, continuing to move the mold drive shaft 11 to the leftmost position within the first slide groove 2, as shown in the following state. Figure 6h As shown.

[0055] S9. Rotate the mold drive shaft 11 clockwise again, and the wire will wrap around the second winding post 18 once, finally returning to its initial state. Figure 6i As shown, two completed double-eared snap rings were obtained.

[0056] During the above decomposition steps, when the cam drive motor 29 is activated, and the planar cam 7 pushes the mold drive shaft 11 to the rightmost side of the first slide 2, the transmission timing belt 10 causes the third drive shaft 12 to be positioned at the uppermost end of the second slide 3. When the second spring 15 returns the mold drive shaft 11 to the leftmost side of the first slide 2, the third drive shaft 12 automatically falls back to the lowermost end of the second slide 3 under the action of the first spring 13. The bushing on the third drive shaft 12 and the bearings on the first drive shaft 9 and the mold drive shaft effectively reduce friction during rotation and reciprocating motion within the slide, making the automatic production process smoother and reducing wear, thus extending the service life of the equipment.

[0057] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
