Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable technology, specifically a tensile-resistant control cable for CNC machine tools. Background Technology
[0002] Currently, CNC machine tools generally use conventional wires and cables. Cables are an indispensable connection line in CNC machine tools. When existing cables are used on CNC machine tools, they are often pulled, causing them to bend or the internal wires to twist. If the cable has poor flexibility, it is easy to damage the cable and reduce its service life. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a tensile-resistant control cable for CNC machine tools, addressing the above-mentioned shortcomings.
[0004] To solve the above technical problems, the present invention adopts the following technical solution:
[0005] A tensile-resistant control cable for CNC machine tools includes a conductor, an insulation layer, a shielding layer, and an inner sheath arranged sequentially from the inside to the outside. The conductor has an insulation layer, a shielding layer, and an inner sheath arranged sequentially from the inside to the outside. The inner sheath has a first toughness layer on its outer side. The first toughness layer is covered by a first isolation layer. The first isolation layer has a second toughness layer on its outer side. The second toughness layer is covered by a second isolation layer. The second isolation layer has an armor layer on its outer side. The armor layer is covered by an outer sheath.
[0006] Furthermore, both the first toughening layer and the second toughening layer are aramid-reinforced core wrapping layers, and the aramid-reinforced core wrapping directions of the first toughening layer and the second toughening layer are opposite.
[0007] Furthermore, the armor layer includes multiple elastic metal sheets arranged in a scale-like pattern, with the rear end of the front elastic metal sheet overlapping the front end of the rear elastic metal sheet, and each elastic metal sheet being a curved rectangular sheet with a thickness of 0.2 mm.
[0008] Furthermore, both the first and second isolation layers are made of polyethylene.
[0009] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:
[0010] This invention significantly enhances the tensile strength of the cable by sequentially constructing a first toughening layer, a first insulating layer, a second toughening layer, and a second insulating layer on the outer side of the inner sheath, followed by an outermost armor layer. This multi-layered structure allows each layer to work synergistically to disperse and resist tensile force, effectively preventing damage to the cable due to tension. In particular, the first and second toughening layers utilize aramid-reinforced core wrapping layers with opposite wrapping directions. This design not only enhances the cable's tensile strength but also improves its flexibility and torsional resistance. The armor layer employs a design of multiple evenly distributed and sequentially overlapping elastic metal sheets, ensuring both tensile strength and good flexibility and elasticity during bending. Simultaneously, the thickness of the elastic metal sheets is moderate, neither too thick to affect the cable's flexibility nor too thin to provide sufficient protection.
[0011] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] like Figure 1-4 As shown, a tensile-resistant control cable for CNC machine tools includes a conductor 1, an insulation layer 2, a shielding layer 3, and an inner sheath 4 arranged sequentially from the inside to the outside. The conductor 1 is surrounded by the insulation layer 2, the shielding layer 3, and the inner sheath 4 arranged sequentially from the inside to the outside. The inner sheath 4 is surrounded by a first toughness layer 5. The first toughness layer 5 is surrounded by a first isolation layer 6. The first isolation layer 6 is surrounded by a second toughness layer 7. The second toughness layer 7 is surrounded by a second isolation layer 8. The second isolation layer 8 is surrounded by an armor layer 9. The armor layer 9 is surrounded by an outer sheath 10.
[0021] In one embodiment, both the first toughness layer 5 and the second toughness layer 7 are aramid reinforcing core wrapping layers, and the aramid reinforcing core wrapping directions of the first toughness layer 5 and the second toughness layer 7 are opposite.
[0022] In one embodiment, the armor layer 9 includes a plurality of elastic metal sheets arranged in a scale-like manner, with the rear end of the front elastic metal sheet overlapping the front end of the rear elastic metal sheet, and each elastic metal sheet being a curved rectangular sheet with a thickness of 0.2 mm.
[0023] In one embodiment, both the first isolation layer 6 and the second isolation layer 8 are made of polyethylene.
[0024] The working principle of this invention is as follows: When the cable is subjected to tensile force, the first toughening layer 5 and the second toughening layer 7 further enhance the tensile strength of the cable. The high strength and good flexibility of the aramid material allow the cable to maintain good elasticity under tensile force and is not easily broken. When the cable is twisted or bent, the opposite wrapping direction of the first toughening layer 5 and the second toughening layer 7 effectively resists torsional force and maintains the stability and integrity of the cable. The elastic metal sheet structure of the armor layer 9 can also adapt to the bending and twisting of the cable and will not break or fall off due to external forces.

The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
