Description

Technical Field

[0001] This utility model relates to the field of aluminum foil bending technology for cables, and in particular to an adjustable width aluminum foil folding device. Background Technology

[0002] Modern electronic devices have an extreme pursuit of high-speed data transmission stability and efficient internal space utilization. High-speed flat cabling is widely used in high-end electronic devices such as servers, base stations, and switches. This type of cabling typically includes a bent aluminum foil layer, the main function of which is to shield against signal interference.

[0003] In current production processes, aluminum foil layers for ribbon cables are typically bent using aluminum foil folding dies. The cavity width of these dies is fixed during manufacturing and cannot be changed; one die corresponds to only one precise width, failing to meet the production needs of ribbon cables with varying widths. While existing aluminum foil folding dies are simple in structure, have short manufacturing cycles, and are inexpensive, changing dies for different ribbon cable production requires downtime, disassembly of the old die, and installation and debugging of the new die, resulting in significant time consumption and severely limiting production efficiency. Furthermore, a separate die needs to be prepared for each ribbon cable specification, leading to a large number of dies and high costs for subsequent management, storage, and maintenance. Therefore, we need an aluminum foil folding device capable of adjusting the width of the folded edge to adapt to the production needs of various ribbon cables. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable width aluminum foil folding device.

[0005] To achieve the above objectives, an adjustable-width aluminum foil folding device includes an upper mold base and a lower mold base corresponding to each other vertically, and a left fixed plate and a right fixed plate corresponding to each other horizontally. An upper mold is slidably connected to the upper mold base along its length, and a lower mold is slidably connected to the lower mold base along its length. The left fixed plate is fixedly connected to the left end of both the upper and lower mold bases, and the right fixed plate is fixedly connected to the right end of both the upper and lower mold bases. The device also includes a pair of parallel adjusting bolts, each bolt comprising an upper mold adjusting bolt for adjusting the position of the upper mold. The upper mold includes a connecting bolt and a lower mold adjusting bolt for adjusting the position of the lower mold. The upper mold adjusting bolt passes through the right fixed plate, the upper mold, and the left fixed plate in sequence. The lower mold adjusting bolt passes through the left fixed plate, the lower mold, and the right fixed plate in sequence. The upper mold adjusting bolt is threaded to the upper mold, and the lower mold adjusting bolt is threaded to the lower mold. The ends of the adjusting bolts are respectively connected to fixing nuts. There are material grooves spaced along the length of the upper and lower molds. The upper mold and the lower mold are respectively provided with a folding groove communicating with the material groove. The folding grooves are respectively arranged at both ends of the material groove.

[0006] The upper mold base is used to install the upper mold, and the lower mold base is used to install the lower mold. The connection between the left and right fixed plates forms a stable structure. The wiring enters through the material trough, and the aluminum foil completes the folding operation through the folding groove. According to the distance of the screw drive, the upper mold adjusting bolt and the lower mold adjusting bolt drive the upper mold and the lower mold to move respectively through the threaded connection, thereby adjusting the length of the material trough to meet the production needs of wiring of different widths. The upper mold adjusting bolt and the lower mold adjusting bolt are equipped with fixing nuts at the ends for fixing and locking the adjusted position of the upper mold and the lower mold.

[0007] Preferably, the upper mold and the lower mold are respectively provided with dovetail grooves along their length direction, and the upper mold base and the lower mold base are respectively provided with guide rails that match the dovetail grooves.

[0008] The dovetail groove is designed to work with the guide rail. It serves two purposes: first, it guides the mold, and second, it prevents the mold from slipping off. After installation, the upper and lower molds are stably connected and are less prone to swaying or falling off.

[0009] Preferably, the adjusting bolt and the fixing nut are respectively provided with a positioning platform at one end, and the fixing nut is provided with a positioning screw that passes through the fixing nut and extends to the positioning platform.

[0010] Vibration during use may cause the fixing nut to slightly shift from its intended position, affecting the locking effect. Therefore, a positioning screw is set up to cooperate with the positioning platform to further tighten the nut and adjusting bolt to ensure accurate positioning.

[0011] Preferably, the adjusting bolts are provided with a turning handle at the end away from the fixing nut.

[0012] The screw-on handle makes it easy to adjust the bolts.

[0013] Preferably, the folding groove shrinks from the feeding end to the discharging end.

[0014] The folding groove drives the aluminum foil to complete the folding action by contracting from both sides of the groove towards the center.

[0015] Preferably, the left and right fixed plates are respectively provided with clearance grooves to allow the upper and lower molds to slide freely.

[0016] The purpose of setting the clearance groove is to prevent motion interference when the upper and lower molds slide.

[0017] Preferably, the left and right fixing plates are respectively provided with a plurality of locking screws and are fixedly connected to the upper mold base and the lower mold base.

[0018] It is secured with screws, making it easy to operate and quick to assemble and disassemble.

[0019] Preferably, the upper mold base and the lower mold base are respectively threaded with mounting screws, and the mounting screws are also connected with mounting nuts.

[0020] The mounting screws are used to connect the upper and lower mold bases to the working machine base. Since the upper and lower mold bases are connected to the mounting screws by threads, mounting nuts are provided to further reinforce the threaded connection and ensure connection stability.

[0021] Compared with the prior art, the beneficial effects of this utility model are: This utility model has an upper mold base for installing the upper mold and a lower mold base for installing the lower mold. The connection of the left and right fixed plates forms a stable structure. The wiring enters through the material trough, and the aluminum foil completes the folding operation through the folding groove. According to the distance of the screw drive, the upper mold adjusting bolt and the lower mold adjusting bolt are connected by threads to drive the upper mold and the lower mold to move respectively, thereby adjusting the length of the material trough to meet the production needs of wiring of different widths. The upper mold adjusting bolt and the lower mold adjusting bolt are fixed with fixing nuts at their ends to lock the adjusted positions of the upper mold and the lower mold.

[0022] This invention allows for varying cavity widths, covering a wide range of sizes to accommodate different cable specifications. Width adjustments can be made quickly without machine downtime, enabling multi-purpose use of a single mold and saving on the manufacturing, storage, and management costs of multiple fixed molds. It is suitable for the production needs of various cable foil folding processes and offers strong compatibility. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. 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.

[0031] This utility model provides an adjustable width aluminum foil folding device, such as... Figures 1-6 As shown, the structure includes an upper mold base 1 and a lower mold base 2, corresponding vertically, and a left fixing plate 3 and a right fixing plate 4, corresponding horizontally. The upper mold base 1 is slidably connected to an upper mold 5 along its length, and the lower mold base 2 is slidably connected to a lower mold 6 along its length. The left fixing plate 3 is fixedly connected to the left ends of both the upper mold base 1 and the lower mold base 2, and the right fixing plate 4 is fixedly connected to the right ends of both the upper mold base 1 and the lower mold base 2, forming an integral structure. It also includes a pair of parallel adjusting bolts 7, including an upper mold adjusting bolt 71 for adjusting the position of the upper mold 2 and a lower mold adjusting bolt 72 for adjusting the position of the lower mold 6. The upper mold 5 can be slidable via the upper mold adjusting bolt 71, and the lower mold 6 can be slidable via the lower mold adjusting bolt 72. A material groove 8 is spaced between the upper mold 5 and the lower mold 6 along their length, through which the feed cable passes. The sliding motion adjusts the length of the material trough 8 accordingly, thus adjusting it based on the feeding requirements of the cable width. The upper mold adjusting bolt 71 passes through the right fixed plate 4, the upper mold 5, and the left fixed plate 3 in sequence, and the lower mold adjusting bolt 72 passes through the left fixed plate 3, the lower mold 6, and the right fixed plate 4 in sequence. The upper mold adjusting bolt 71 is threadedly connected to the upper mold 5, and the lower mold adjusting bolt 72 is threadedly connected to the lower mold 6. According to the screw drive principle, the upper mold adjusting bolt 71 and the lower mold adjusting bolt 72 drive the upper mold 5 and the lower mold 6 to slide through the threaded connection. Considering the fixation problem after the position adjustment, the ends of the adjusting bolts 7 are respectively connected to fixing nuts 73. The fixing nuts 73 lock the adjusting bolts 7 to prevent further rotation. For the requirement of aluminum foil folding, the upper mold 5 and the lower mold 6 are respectively provided with a folding groove 81 communicating with the material trough 8. The folding groove 81 is respectively arranged at both ends of the material trough 8, and the aluminum foil is folded when passing through the folding groove 8. The folding groove 81 can be implemented using any existing technology.

[0032] During the movement of the upper mold 5 and the lower mold 6, it is necessary to ensure the connection stability of the upper mold 5 and the lower mold 6 to prevent deviation and shaking, and it is also necessary to guide the movement. Therefore, the upper mold 5 and the lower mold 6 are respectively provided with dovetail grooves 9 along their length direction, and the upper mold base 1 and the lower mold base 2 are respectively provided with guide rails 91 that match the dovetail grooves 9. The stable guiding effect of the dovetail grooves 9 is used to ensure the stable operation of the upper mold 5 and the lower mold 6.

[0033] Considering that the adjusting bolt 7 is locked by the fixing nut 73, machine vibration during the production process may cause the fixing nut 73 to loosen, affecting the fixing effect, a positioning platform 74 is provided at the connection end of the adjusting bolt 7 and the fixing nut 73. The positioning platform 74 is flat. The fixing nut 73 is provided with a positioning screw 75 that passes through the fixing nut 73 and extends to the positioning platform 74. After tightening the positioning screw 75, the positioning screw 75 is vertically pressed against the positioning platform 74, which further fixes the connection between the fixing nut 73 and the adjusting bolt 7.

[0034] The adjusting bolt 7 is provided with a turning handle 76 at the end away from the fixing nut 73. When adjusting, the fixing nut 73 can be loosened, and the adjusting bolt 7 can be adjusted by turning the handle 76.

[0035] The folding groove 81 contracts from the feeding end to the discharging end. When the aluminum foil passes through the folding groove 81, it contracts from both sides to the middle, thus completing the folding operation.

[0036] Considering that the upper mold 5 and the lower mold 6 may interfere with the left fixed plate 3 and the right fixed plate 4 during the sliding process, the left fixed plate 3 and the right fixed plate 4 are respectively provided with clearance grooves 10 to avoid the sliding of the upper mold 5 and the lower mold 6.

[0037] The left fixing plate 3 and the right fixing plate 4 are respectively provided with a plurality of locking screws 11, which are fixedly connected to the upper mold base 1 and the lower mold base 2.

[0038] The upper mold base 1 and the lower mold base 2 are respectively threaded with mounting screws 12. The upper mold base 1 and the lower mold base 2 can be fixed to the workbench by the mounting screws 12. Considering that the upper mold base 1 and the lower mold base 2 are connected to the mounting screws 12 by threads, the mounting screws 12 are also connected with mounting nuts 13. The mounting nuts 13 are used for further tightening to ensure the stability of the connection between the upper mold base 1, the lower mold base 2 and the mounting screws 12.

[0039] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
