Description

Technical Field

[0001] The utility model relates to the technical field of cables, and specifically relates to a high-flexibility machine tool drag chain flat power supply cable. Background Technique

[0002] A drag chain is a device that restrains cables to facilitate their rotation and movement. Most machine tools are equipped with a drag chain system. The machine tool drag chain cable generally uses a flat high-flexibility cable, which can freely bend and move back and forth following the drag chain.

[0003] The existing high-flexibility machine tool drag chain flat power supply cable often bends as the drag chain box moves. If the overall flexibility of the cable is not good enough, the internal conductors of the cable are easily damaged, which will affect the use of the cable. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a high-flexibility machine tool drag chain flat power supply cable aiming at the above deficiencies.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A high-flexibility machine tool drag chain flat power supply cable includes a strengthening core, conductors, insulating layers, an inner sheath, a shielding layer and an outer sheath. A plurality of conductors are arranged in parallel on the outer side of the strengthening core. Each conductor is coated with an insulating layer on the outside. Adjacent conductors coated with insulating layers are wound around each other to form a twisted pair conductor unit. The strengthening core and all the twisted pair conductor units are wrapped in an inner sheath. The outer side of the inner sheath is coated with a shielding layer, and the outer side of the shielding layer is coated with an outer sheath. A plurality of reinforcing wires are embedded in the outer sheath.

[0007] Furthermore, a plurality of the reinforcing wires are symmetrically distributed in parallel along the upper and lower sides of the outer sheath.

[0008] Furthermore, the material of the reinforcing wire is steel wire.

[0009] Furthermore, the material of the strengthening core is an aramid fiber strengthening core.

[0010] After the utility model adopts the above technical solutions, compared with the prior art, it has the following advantages:

[0011] The utility model adopts the design of multiple wires wound around each other to form a twisted pair wire unit, which increases the freedom degree of the cable during bending, effectively disperses the bending stress, and thus significantly improves the flexibility of the cable. This design enables the internal wires of the cable to be not easily damaged when the cable bends frequently along with the movement of the drag chain box, extending the service life of the cable; the setting of the strengthening core not only provides axial support for the cable, but also enhances the overall tensile strength of the cable. At the same time, the inner protective layer not only covers the outside of the wires, but also covers the outside of the strengthening core, forming an all-round protection for the internal structure of the cable. In addition, multiple strengthening wires are arranged on the inner side of the shielding layer, especially the design symmetrically distributed along the upper and lower sides of the outer protective layer, further enhancing the flexibility of the cable; the outer protective layer is made of wear-resistant and oil-resistant materials such as polyurethane or chloroprene rubber, and these materials have excellent wear resistance and chemical corrosion resistance, and can effectively protect the internal structure of the cable from the influence of the external environment, especially from the erosion of corrosive substances such as oil stains and cutting fluids that may be encountered in the working environment of machine tools.

[0018] Such as Figure 1As shown in the figure, a high-flexibility machine tool drag chain flat power supply cable includes a strengthening core 1, conductors 2, insulating layers 3, an inner protective layer 4, a shielding layer 5, and an outer protective layer 6. Multiple conductors 2 are arranged in parallel on the outer side of the strengthening core 1. Each conductor 2 is coated with an insulating layer 3 on the outer side. Adjacent conductors 2 coated with insulating layers 3 are wound around each other to form a twisted pair conductor 2 unit. The strengthening core 1 and all the twisted pair conductor 2 units are wrapped in an inner protective layer 4. The outer side of the inner protective layer 4 is coated with a shielding layer 5. The outer side of the shielding layer 5 is coated with an outer protective layer 6. Multiple strengthening wires 7 are embedded in the outer protective layer 6.

[0019] As an implementation manner, multiple said strengthening wires 7 are symmetrically distributed in parallel along the upper and lower sides of the outer protective layer 6.

[0020] As an implementation manner, the material of the strengthening wire 7 is steel wire.

[0022] The working process of the present utility model: During the process of the cable bending back and forth with the drag chain, the two conductors 2 of the twisted pair conductor unit bend along with the cable. The twisted pair structure enhances the toughness between the two conductors 2. The strengthening core 1 and multiple strengthening wires 7 also bend simultaneously, enhancing the overall flexibility of the cable.
