[0002] Optical fiber cable is a communication cable assembly manufactured to meet optical, mechanical, or environmental performance specifications. With the increase in communication density, the use of optical fiber cable is increasing, and the requirements for optical fiber cable performance are also becoming higher. Ordinary carbon steel tape and aluminum steel tape can no longer meet the requirements of special cables, so stainless steel tape is widely used. Compared with ordinary carbon steel tape, stainless steel tape has the advantages of being less prone to rust and having better rigidity, while compared with aluminum tape, stainless steel tape has better tensile strength.

[0003] Because stainless steel strip is more rigid than carbon steel strip and aluminum strip, it is more difficult to form. After being formed by existing molds, stainless steel strip will rebound and the overlapping position is easy to misalign, which will affect the final structure and performance of the cable.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention. Example 1

[0028] Reference Figures 1-5 As shown, this utility model discloses a stainless steel strip post-forming device, comprising,

[0029] Mounting base 1, with a central through hole 11 coaxially formed on the mounting base 1, and two parallel mounting plates 12 symmetrically arranged at one end of the mounting base 1, with the two mounting plates 12 located on both sides of the central through hole 11 and parallel to it.

[0030] The sizing die assembly 2 includes a sizing die base 21 and a sizing die 22. The sizing die base 21 is disposed in the central through hole 11, and a die hole 211 is coaxially opened on the sizing die base 21. The sizing die 22 is installed in the die hole 211, and a sizing hole 221 is coaxially opened on the sizing die 22.

[0031] The sizing wheel assembly 3 includes a mandrel 31 and forming rollers 32. Two sets of mandrels 31 are provided, which are vertically connected between the two mounting plates 12 and are symmetrically arranged on both sides of the central through hole 11. Two forming rollers 32 are provided and are rotatably connected to the two mandrels 31 respectively. Annular arc grooves 321 are opened on the circumferential surface of each forming roller 32.

[0032] Specifically, the stainless steel strip post-forming device is set at the output end of the existing forming mold. The cable output from the forming mold is coaxially inserted into the sizing hole 221 of the sizing mold 22, increasing the forming distance and forming time, thereby reducing the springback and stress release process of the formed stainless steel strip. Furthermore, the two forming rollers 32 of the sizing roller assembly 3 at the rear end of the sizing mold assembly 2 can perform a second extrusion and shaping process on the cable passing between them, so that the cable has better roundness and avoids the occurrence of misalignment of the stainless steel strip overlap position, ensuring the final performance of the cable.

[0033] Reference Figure 1 , Figure 2 and Figure 3 As shown, the forming roller 32 is rotatably connected to the mandrel 31 via a bearing 33. Two bushings 34 are fitted onto the mandrel 31, located between the two mounting plates 12 and the forming roller 32, respectively. One end of each bushing 34 abuts against the bearing 33, and the other end abuts against one of the mounting plates 12. Specifically, the two bushings 34 located on both sides of the forming roller 32, in conjunction with the mounting plates 12 and the bearings 33, limit the movement of the forming roller 32, preventing axial movement and ensuring the symmetry of the two forming rollers 32, which is beneficial to the cable forming process.

[0034] Reference Figure 4 As shown, furthermore, each end of the two mounting plates 12 has a U-shaped groove 121, and each end of the mounting plate 12 is connected in parallel to a pressure plate 13 by fasteners. A shaft hole is formed between the pressure plate 13 and the U-shaped groove 121, and both ends of the mandrel 31 pass through one of the shaft holes. Specifically, the distance between the pressure plate 13 and the mounting plate 12 can be adjusted according to different needs to adjust the distance between the two forming rollers 32 during the forming process.

[0035] Furthermore, the mounting plate 12 has two first bolt holes symmetrically opened at both ends, located on both sides of the U-shaped groove 121 respectively. The pressure plate 13 has a second bolt hole corresponding to the position of the two first bolt holes. The pressure plate 13 is connected to the mounting base 1 by bolts at the corresponding first bolt holes and second bolt holes.

[0036] Furthermore, flat areas are machined on the sides of both ends of the mandrel 31. The flat areas on the mandrel 31 can increase the contact area between the pressure plate 13 and the mandrel 31, which can improve the stability of the mandrel 31 and the forming roller 32 to a certain extent.

[0037] Furthermore, the die hole 211 is a stepped hole, and the shape of the sizing die 22 matches the shape of the die hole 211 and is fitted into the die hole 211. Specifically, the sizing die holder 21 and the sizing die 22 are detachably connected, and the sizing die holder 21 and the mounting base 1 are also detachably connected; this allows for the provision of various sizing die holders 21 and sizing dies 22 with different specifications of die holes 211 and sizing holes 221, which can be combined according to actual needs, improving the versatility of the entire equipment.

[0038] Furthermore, the end of the sizing hole 221 away from the sizing wheel assembly 3 is provided with a chamfer or rounded corner. The chamfer or rounded corner can guide the cable passing through the sizing hole 221 and also reduce the friction between the sizing die 22 and the cable. This reduces the wear of the cable and the sizing die 22, while making the cable run more smoothly.

[0039] Furthermore, the mounting base 1 has a clearance groove located between the two mounting plates 12. Specifically, the position of the clearance groove corresponds to the position of the two forming rollers 32, and the clearance groove provides sufficient installation space for the forming rollers 32 and makes the entire structure more compact. The width of the clearance groove can be set according to the specific width of the forming rollers 32.

[0040] Furthermore, the mounting base 1 and the mounting plate 12 are integrally formed structures. Example 2

[0041] This utility model also discloses a production line, including a stainless steel strip post-forming device as described in Embodiment 1.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
