Description

Technical Field

[0001] This utility model relates to the field of aluminum foil longitudinal wrapping mold technology, and in particular to a multi-slider segment aluminum foil longitudinal wrapping mold. Background Technology

[0002] In cable manufacturing, the aluminum foil longitudinal wrapping process is a crucial step in achieving material protection and performance optimization. The aluminum foil longitudinal wrapping mold, as the core forming component of this process, directly determines the quality and production efficiency of the wrapped products through its structural design and performance. This is especially true for data signal cables used in high-speed transmission applications such as AI, humanoid robots, and urban big data center servers, which have stringent requirements for the precision of aluminum foil longitudinal wrapping. Currently, many small and medium-sized manufacturers in the industry, in order to control equipment investment costs, still commonly use simple aluminum foil longitudinal wrapping molds for production. These simple molds only have basic guiding and wrapping functions and lack a precise control mechanism for the aluminum foil forming process. Due to the lack of precise guiding control during the aluminum foil wrapping process, uneven stress can easily cause local wrinkles when the aluminum foil passes through the mold cavity. Especially in the processing of thin materials with a aluminum foil thickness of less than 0.05mm, the wrinkle defect rate can be as high as 30% or more. Furthermore, longitudinal wrapping eccentricity is very likely to occur during the process, seriously affecting product quality and leading to a high scrap rate. Furthermore, the operation of simple aluminum foil longitudinal wrapping molds is highly dependent on the experience and skill of technicians. Workers need to repeatedly adjust parameters such as mold position and feeding speed manually to try to improve the forming effect, which not only increases the labor intensity of operators but also leads to extremely poor production stability. When changing to different specifications of aluminum foil or substrate, parameter debugging usually takes more than 2 hours, and the proportion of defective products generated during the debugging process exceeds 15%, significantly increasing the scrap rate and restricting the company's capacity improvement and market competitiveness.

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0033] This utility model provides a multi-slider segmented aluminum foil longitudinal wrapping mold, such as Figures 1-8As shown, the device includes a guide rail 1, with a gathering module 2 at its rear end. The core wire and aluminum foil complete the core-wrapping process in the gathering module 2 and are then discharged. The guide rail 1 has a groove 11 along its length, and a slider assembly is matched and connected to the groove 11. The slider assembly includes multiple sliders. Each slider and the gathering module 2 is fixedly connected to the guide rail 1 by a fixing member 3. The position of the slider can be adjusted by moving the slider and fixing it with the fixing member 3. Each slider has a core wire hole that passes through it. 4 and strip-shaped aluminum foil groove 5, the core wire passes through the core wire hole 4 and the aluminum foil passes through the aluminum foil groove 5. The slider gradually deforms along the processing direction of the aluminum foil groove 5 and shrinks towards the core wire hole 4 until the end of the aluminum foil groove 5 connects with the core wire hole 4 to guide the aluminum foil to wrap the core wire. The aluminum foil is precisely deformed and gradually wraps the core wire through the aluminum foil groove 5. Finally, the aluminum foil groove 5 and the core wire hole 4 are connected and merged to complete the high-precision longitudinal wrapping of the core wire by the aluminum foil. The gathering module 2 is provided with a discharge hole 21. The core wire wrapped with aluminum foil is finally discharged from the discharge hole 21. The slider assembly consists of multiple sliders arranged sequentially. Each slider has a core wire hole 4 and an aluminum foil groove 5. The aluminum foil groove 5 gradually contracts and deforms towards the core wire hole 4, connecting with the core wire hole 4, forming a segmented, step-by-step aluminum foil longitudinal wrapping process. This achieves high-precision aluminum foil wrapping of the core wire. Each slider is slidable and can be fixed to the track 1 by a fixing component. The longitudinal wrapping process of the aluminum foil is adjusted by adjusting the sliders to ensure processing accuracy. Through the multi-segment precision guidance of the sliders, the aluminum foil is driven to gradually produce high-precision deformation, ultimately completing the wrapping of the core wire. The mold guidance is precise, and the aluminum foil is subjected to uniform force within the mold cavity, avoiding problems such as longitudinal wrapping eccentricity and aluminum foil wrinkles. Moreover, the processing is convenient and efficient, without relying on the experience and skill of technical workers.

The bottom of the groove 5 connects with the core wire hole 4, wrapping the bottom of the core wire. Simultaneously, one side of the U-shaped aluminum foil groove 5 folds upwards towards the core wire hole 4, preparing for the next connection and merging step. The fourth slider 40 has one side of its aluminum foil groove 5 fully connected to the core wire hole 4, while the other side folds upwards towards the core wire hole 4. At the fourth slider 40, the U-shaped aluminum foil groove 5 has folded one side, connecting with the core wire hole 4, completing most of the core wire wrapping. The other side of the aluminum foil groove 5 folds upwards towards the core wire hole 4. At the discharge hole 21, the aluminum foil finally wraps the core wire and discharges.

[0039] Considering that the aluminum foil and core wire are continuously fed during the longitudinal wrapping of aluminum foil, a guide tube 8 is provided at the front end of the guide rail 1 in order to guide the core wire and aluminum foil during processing. The guide tube 8 can also support the core wire and aluminum foil to prevent deformation. The end of the guide tube 8 is fitted inside the protective sleeve 6. Considering the problem of fixing the guide tube 8, the protective sleeve 6 is provided with multiple tightening screws 63 to abut against the guide tube 8 to fix the guide tube 8.

[0040] Considering that the aluminum foil longitudinal wrapping mold needs to be installed on the corresponding equipment for aluminum foil longitudinal wrapping processing, the front end of the sheath 6 is provided with a clamping part 64 for installing and fixing the sheath 6. The sheath 6 can be fixed by the clamping part 64, thereby fixing the entire mold.

[0041] Considering that some cables have a ground wire and the ground wire does not need to be wrapped with aluminum foil, the slider and the gathering module 2 are also provided with at least one ground wire hole 9. The ground wire hole 9 is front and back, and the ground wire is guided through the ground wire hole 9. The ground wire hole 9 is located on one side of the core wire hole 4 and does not interfere with the shrinkage and deformation of the aluminum foil groove 5.
