[0029] 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.

[0030] Example

[0031] like Figure 1-4 As shown, an embodiment of this utility model provides a snap ring conversion and shaping mechanism, comprising:

[0032] Snap ring positioning component 1, used to position snap ring 4 with shaping;

[0033] The shaping drive component 2 includes two symmetrically arranged shaping rods 21. One end of each of the two shaping rods 21 extends to both sides of the retaining spring positioning component 1 and is respectively opposite to the shaping part 41 on both sides of the retaining spring 4.

[0034] The driving mechanism 3 is used to drive the shaping driving component 2 to compress and shape the retaining ring 4.

[0035] like Figure 1-4 As shown, in some embodiments, the snap ring positioning member 1 is U-shaped, and positioning notches 11 are provided on both sides of the snap ring positioning member 1.

[0036] The U-shaped retaining ring positioning part 1 matches the tail shape of the retaining ring 4. The U-shaped groove inside, combined with the springback characteristic of the retaining ring 4, allows the retaining ring 4 to be positioned by slightly compressing it when it is inserted into the retaining ring positioning part 1. This prevents the retaining ring 4 from shifting during the shaping process and ensures the stability and accuracy of the shaping operation.

[0037] like Figure 1-4 As shown, in some embodiments, one end of the shaping rod 21 is provided with a pressing head 22 that extends into the positioning notch 11.

[0038] The extrusion head 22 enters the positioning notch 11 and can pre-clamp the parts 41 to be shaped on both sides of the retaining spring 4 under the action of the balance spring 23 supporting the shaping rod 21, so that the extrusion head 22 and the parts 41 to be shaped are precisely aligned. At the same time, the extrusion head 22 can be guided to avoid swaying during the extrusion process and improve the consistency of the shaping effect.

[0039] like Figure 1-4 As shown, in some embodiments, a balance spring 23 is provided between the two shaping rods 21.

[0040] The balance spring 23 connects the two shaping rods 21 to ensure that they move synchronously during the driving process, avoid the problem of skew caused by unilateral force, make the force on both sides of the retaining spring 4 uniform, and improve the shaping quality.

[0041] A snap-fit ​​is provided between the two shaping rods 21 to engage with the two ends of the balance spring 23, thus preventing the ends of the balance spring 23 from falling off.

[0042] like Figure 1-4 As shown, in some embodiments, a return spring 24 is provided at the end of the shaping rod 21 away from the extrusion head 22.

[0043] The return spring 24 can provide restoring force to the shaping rod 21 after the drive mechanism 3 returns to its original position, so that it can automatically return to its initial position and prepare for the next shaping operation, thereby improving the efficiency of continuous operation of the equipment.

[0044] During the shaping process, the reset spring 24 is in the compression process and the balance spring 23 is in the extension process; during the reset process, the reset spring 24 is in the extension process and the balance spring 23 is in the compression process.

[0045] like Figure 1-4 As shown, in some embodiments, a lower mold fixing plate 5 is also included. The shaping rod 21 is rotatably mounted on the top of the lower mold fixing plate 5 via a rotating shaft 25. A mold base 51 is provided at the bottom of the lower mold fixing plate 5. A mold top plate 6 is movably connected to the top of the mold base 51 via a guide rod 52.

[0046] The snap ring positioning component 1 is fixedly installed on the top of the lower mold fixing plate 5. Through the combined design of the lower mold fixing plate 5, the mold base 51 and the mold top plate 6, it provides stable support and precise guidance for the entire mechanism, ensuring the stability and reliability of the movement of each component during the forming process.

[0047] like Figure 1-4 As shown, in some embodiments, two limiting members 53 are fixedly provided on the top of the mold lower fixing plate 5, and one side of the limiting member 53 is movably engaged with the end of the reset spring 24 away from the extrusion head 22.

[0048] The limiting member 53 and the shaping rod 21 are also provided with a buckle that engages with the two ends of the return spring 24, providing a reliable fixing point for the return spring 24 and limiting its range of motion. This prevents the ends of the spring from falling off during compression and rebound, ensuring the accuracy and consistency of the reset action. Furthermore, the shaping rod 21 performs a rotational compression operation with a short rotational stroke, resulting in small compression and extension amplitudes of the balance spring 23 and the return spring 24, preventing significant fluctuations and making the operation more stable.

[0049] like Figure 1-4 As shown, in some embodiments, the drive mechanism 3 includes a punch connecting seat 31 disposed at the bottom of the mold top plate 6, and an upper punch 32 is disposed inside the punch connecting seat 31.

[0050] The punch connecting seat 31 securely connects the upper punch 32 to the mold top plate 6, ensuring the effective transmission of driving force so that the upper punch 32 can accurately act on the forming rod 21 to complete the forming action. The mold top plate 6 is connected to the stamping power source, which can be flywheel stamping, cylinder stamping, hydraulic steel stamping, etc.

[0051] like Figure 1-4 As shown, in some embodiments, the bottom of both sides of the upper punch 32 is provided with inclined surfaces, and the upper punch 32 is located directly above the end of the two shaping rods 21 away from the extrusion head 22.

[0052] The inclined surface design at the bottom of the upper punch 32 can contact the shaping rod 21 during the downward movement, converting the vertical driving force into the horizontal extrusion force, so that the two shaping rods 21 rotate simultaneously around the pivot 25, causing the shaping rods 21 to drive the extrusion head 22 to extrude the part 41 of the retaining spring 4 into place. By adjusting the downward height of the upper punch 32, the part 41 of the retaining spring 4 to be shaped can reach the required size.

[0053] In summary, by cooperating with the snap ring positioning component 1 and the symmetrically arranged shaping rods 21, the snap ring 4 is quickly and accurately positioned and extruded for shaping. The overall structure is simple and compact, effectively reducing manufacturing costs and minimizing the mold size. The vertical linear motion of the drive mechanism 3 is converted into the horizontal opposing motion of the shaping rods 21, allowing operators to safely hold the product for shaping without having to put their hands inside the mold. This significantly improves production efficiency and operational safety. The mechanism is stable and reliable in operation and is very suitable for on-site shaping of small workpieces.

[0054] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
