Abstract
Description
Technical Field
[0001] This utility model relates to the field of bare copper stranded wire production technology, and more specifically, to a cutting device for bare copper stranded wire production. Background Technology
[0002] Bare copper stranded wire is a conductive material made by twisting multiple bare copper wires together according to specific rules. It is widely used in overhead transmission lines, grounding systems, and busbars of electrical equipment. Its core advantages are excellent conductivity, high mechanical strength, and good heat dissipation. After production, bare copper stranded wire needs to be cut into fixed lengths according to customer requirements.
[0003] Most existing bare copper stranded wire cutting equipment uses a telescopic cylinder to connect the cutting blade. The telescopic cylinder pushes the cutting blade to cut the bare copper stranded wire. This cutting method has high shear resistance on the bare copper stranded wire, which can easily cause the bare copper stranded wire to unravel and affect subsequent processing. Utility Model Content
[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a cutting device for bare copper strand production that reduces shear resistance and prevents bare copper strands from unraveling.
[0005] To solve the above problems, the present invention adopts the following technical solution.
[0006] A cutting device for producing bare copper stranded wire, comprising: Base; A wire feeding mechanism, mounted on the base, is used to feed out bare copper stranded wire; The preheating mechanism is movable back and forth on the base and is located on the output side of the wire feeding mechanism, and is used to heat the bare copper stranded wire; An air jetting mechanism, mounted on the base and located between the preheating mechanism and the wire feeding mechanism, is used to spray inert gas onto the bare copper strands to protect them from oxidation; and A cutting mechanism is mounted on the base and located on the side of the preheating mechanism away from the wire feeding mechanism, and is used to cut bare copper stranded wire.
[0007] The technical solution described above in this application example has at least the following technical effects: The cutting equipment is equipped with a preheating mechanism that preheats and softens the bare copper strands before the cutting structure cuts them. This process softens the bare copper strands by preheating them before cutting, reducing shear stress, improving cutting efficiency, and preventing burrs and loose strands. Additionally, the equipment is equipped with an air jetting mechanism that sprays inert gas onto the bare copper strands to form a protective film on their surface, preventing oxidation and improving the quality of the bare copper strands.
[0008] In some embodiments, the preheating mechanism includes: Frame; A sleeve, disposed on the frame; and An induction heating coil is arranged around the bare copper stranded wire on the inner wall of the sleeve for induction heating of the bare copper stranded wire.
[0009] In some embodiments, the jetting mechanism consists of a plurality of jet heads disposed around the bare copper stranded wire on the inner wall of the sleeve for ejecting inert gas.
[0010] In some embodiments, the sleeve is a sealed container; the sleeve has through holes at both ends for the entry and exit of bare copper stranded wires.
[0011] In some embodiments, the cutting mechanism includes: The mounting bracket is disposed on the base and located on the side of the preheating mechanism away from the wire feeding mechanism; A cutting table is mounted on the mounting frame; A cutting blade, mounted on the mounting bracket and positioned directly above the cutting table, is used to cut bare copper stranded wires; and A driver, mounted on the mounting bracket and with its output connected to the cutting blade, is used to drive the cutting blade to move downwards.

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1 A cutting device for producing bare copper stranded wire is provided, comprising a base 10, a wire feeding mechanism 20 disposed on the base 10 for feeding bare copper stranded wire, a preheating mechanism 30 movable on the base 10 and located on the output side of the wire feeding mechanism 20 for heating the bare copper stranded wire, an air jetting mechanism 40 disposed on the base 10 and located between the preheating mechanism 30 and the wire feeding mechanism 20 for spraying inert gas onto the bare copper stranded wire to protect it from oxidation, and a cutting mechanism 50 disposed on the base 10 and located on the side of the preheating mechanism 30 away from the wire feeding mechanism 20 for cutting the bare copper stranded wire.
[0016] Understandably, the wire feeding mechanism 20 is a mechanism that releases the bare copper stranded wire. It can be a passive or active wire feeding mechanism, but is not limited to these. The preheating mechanism 30 is a component that softens part of the bare copper stranded wire. It can be a high-frequency induction heating mechanism or a resistance preheating mechanism, but is not limited to these. The air jet mechanism 40 is a component that removes oxygen from around the bare copper stranded wire, forming an inert gas protective film around it. The cutting mechanism 50 is a component that cuts the bare copper stranded wire with a blade. It can be a hydraulic or pneumatic cutting mechanism, but is not limited to these.
[0017] As can be seen from the above, the cutting equipment is equipped with a preheating mechanism 30, which preheats and softens the bare copper strands. Finally, the cutting mechanism 50 cuts the bare copper strands. It can be seen that by preheating the bare copper strands before cutting, the bare copper strands are softened, the shearing stress is reduced, the shearing efficiency is improved, and burrs and loose strands are prevented from appearing on the bare copper strands. At the same time, the equipment is also equipped with an air jet mechanism 40, which sprays inert gas onto the bare copper strands to form a protective film on the surface of the bare copper strands to prevent oxidation and improve the quality of the bare copper strands.
[0018] Optionally, in some embodiments, please refer to Figure 3 The preheating mechanism 30 includes: a frame 31; a sleeve 32 disposed on the frame 31; and an induction heating coil 33 disposed on the frame 31 for induction heating of bare copper stranded wire.
[0019] Understandably, sleeve 32 is a place for partially heating the bare copper stranded wire. For example, it can be a fully enclosed sleeve 32 or a semi-enclosed sleeve 32, but it is not limited to these. The induction heating coil 33 is a component that generates eddy currents through electromagnetic induction to locally heat the bare copper wire. For example, it can be a spiral coil or a toroidal coil, but it is not limited to these.
[0020] This configuration allows for precise localized heating of the bare copper stranded wires via the induction heating coil 33, preventing other parts of the bare copper stranded wires from being heated.
[0021] Optionally, in some embodiments, please refer to Figure 3 The jetting mechanism 40 consists of several jet heads 41 arranged around the bare copper stranded wire on the inner wall of the sleeve 32, used to jet out inert gas.
[0022] Understandably, the jet head 41 is a component that ejects gas. For example, it can be an annular jet head 41 or a single-hole direct injection jet head 41, but it is not limited to these.
[0023] This configuration prevents inert gas from leaking out through the jet nozzle 41 onto the bare copper stranded wire sleeve 32, thus avoiding air pollution from inert gas leakage.
[0024] Optionally, in some embodiments, please refer to Figure 4 The cutting mechanism 50 includes: a mounting bracket 51, mounted on the base 10 and located on the side of the preheating mechanism 30 away from the wire feeding mechanism 20; a cutting table 52, mounted on the mounting bracket 51; a cutting blade 53, mounted on the mounting bracket 51 and located directly above the cutting table 52, for cutting bare copper stranded wire; and a driver 54, mounted on the mounting bracket 51, with its output end connected to the cutting blade 53, for driving the cutting blade 53 to move downwards.
[0025] Understandably, the cutting table 52 is a support platform for placing the bare copper stranded wire and performing the cutting work. For example, it can be a U-shaped cutting table 52 or a V-shaped cutting table 52, but it is not limited to these. The cutting blade 53 is a tool for cutting the bare copper stranded wire. For example, it can be a serrated cutting blade 53 or a regular cutting blade 53, but it is not limited to these.
[0026] With this setup, the bare copper stranded wire is cut by the cutting blade 53 driven by the driver 54, eliminating the need for manual cutting by workers and saving labor costs.
[0027] As can be seen from the above, the bare copper stranded wire is pulled out from the wire feeding mechanism 20, passes through the sleeve 32, and then passes through the cutting table 52 to straighten the bare copper stranded wire. The wire feeding begins, the jetting mechanism 40 jets air to fill the sleeve 32 with inert gas, the induction heating coil 33 is activated to heat the bare copper stranded wire, and then the bare copper stranded wire is pulled out to the cutting mechanism 50, where the cutting blade 53 cuts the bare copper stranded wire.
[0028] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
