Description

Technical Field

[0001] This utility model relates to the field of cable wire processing technology, specifically a wire drawing machine for low-voltage cables. Background Technology

[0002] Low-voltage cable wire drawing machines are specialized equipment that use a multi-pass continuous drawing process to gradually reduce the diameter of metal wires (such as copper and aluminum) to the required specifications. Their core function is to precisely process thick metal wires into standard fine wires that meet the conductivity requirements of low-voltage cables. Since the conductivity, flexibility, and compatibility of the outer insulation layer of cables all depend on the precise control of the wire diameter, this type of equipment uses controllable cold deformation processing to enable the wires to obtain uniform cross-sectional dimensions, higher mechanical strength, and better electrical performance, thereby meeting the rigid requirements of the low-voltage power transmission field for wire core consistency, reliability, and production efficiency.

[0003] However, traditional equipment, due to the fixed height of the rotating wheel and the lack of a progressive lifting structure, is prone to overlapping or misalignment of the cable wires during winding, increasing the risk of wire breakage and affecting the uniformity of stretching; in addition, conventional molds have limited adjustment capabilities for mounting positions and insufficient heat dissipation, making it difficult to adapt to the precise angle alignment requirements of different wire diameters, and the electromagnetic system is prone to tension fluctuations due to uncontrolled temperature rise during long-term operation.

Detailed Implementation

[0016] 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.

[0017] Please see Figures 1-5 As shown, this utility model provides a technical solution: A low-voltage cable wire drawing machine includes a slide table 101. The top of the slide table 101 is provided with three sets of sliding grooves 102. Each set of sliding grooves 102 consists of two parts, and each set of sliding grooves 102 is slidably installed with a sliding block 103. The top of each sliding block 103 is connected to an assembly table 104 by bolts. The top of the assembly table 104 is provided with molds 105 of progressively increasing height by bolts. Each mold 105 has a wire drawing hole 106 of progressively decreasing diameter at its center.

[0018] The above scheme allows for the guidance of three sets of position adjustment units through three sets of sliding grooves at the top of the slide table; two sliding blocks slidably installed in each set of sliding grooves can move synchronously and bear the load; the assembly table connected by bolts at the top of the sliding blocks enables flexible positioning of the mold installation platform; the mold with increasing height installed by bolts on the assembly table forms a progressive processing station; and the wire drawing hole with decreasing diameter at the center of the mold enables the physical deformation of the cable wire to gradually reduce its diameter.

[0019] In this embodiment, preferably, the top of the slide table 101 is bolted to an assembly plate 107 adjacent to each group of sliding grooves 102, forming a first group, a second group, and a third group of assembly plates 107. The top of the second group and the third group of assembly plates 107 are respectively provided with a height-increasing platform 118 with progressively increasing height.

[0020] The above scheme constructs stable wheel system support points by bolting assembly plates at adjacent sliding grooves of each group of slide plates; a gradient lifting structure is formed by the incrementally heightening platforms set at the top of the second and third groups of assembly plates; and the height difference enables automatic path guidance of the cable wires without overlapping or tangling when transitioning between rotating wheels.

[0021] In this embodiment, preferably, the height of the first assembly plate 107 is lower than that of all the height-increasing platforms 118, and rotating wheels 109 are rotatably installed on the top of the first assembly plate 107 and the height-increasing platforms 118 in sequence. The center of each rotating wheel 109 is provided with a rotating shaft 110.

[0022] The above scheme ensures that the rotating wheels form a stepped layout by combining the low-height base of the first assembly plate with the top of the elevation platform; the rotating wheels, which are rotatably installed on the progressively higher support surface, provide an interference-free guide wire path; and the rotational power is transmitted to the magnetic control system through the rotating shaft at the center of the rotating wheels.

[0023] In this embodiment, preferably, the bottom end of the rotating shaft 110 passes through and extends into the housing 111 and is connected to the rotor end of the magnetic powder clutch 112. The support seat of the magnetic powder clutch 112 is respectively installed at the bottom end of the support platform 108 by bolts.

[0024] The above scheme achieves power coupling by extending the rotating shaft downwards into the housing to the rotor end of the magnetic powder clutch; the magnetic powder clutch support seat is bolted to the bottom of the support platform to form an inverted load-bearing structure; and the characteristics of the magnetic powder medium enable precise electromagnetic control of the transmission torque of the rotating wheel.

[0025] In this embodiment, preferably, the support platform 108 is fixedly installed on the top of the housing 111, and the four corners of the bottom of the housing 111 are respectively equipped with support legs 113, and the input end of the magnetic powder clutch 112 is respectively connected to the output shaft of the motor 114.

[0026] The above scheme forms a closed transmission chamber by fixing the support platform at the top of the housing; the four corner supports at the bottom of the housing provide stable support for the whole machine; and the direct shaft connection between the magnetic powder clutch input end and the motor output end achieves efficient power transmission.

[0027] In this embodiment, preferably, the housing of the motor 114 is provided with connecting plates 117, and the connecting plates 117 are respectively installed on the magnetic powder clutch 112 support seat at one end opposite to the support platform 108 by bolts.

[0028] The above scheme secures the power source to the magnetic powder clutch support by bolting the motor housing connecting plate; the double-end support structure eliminates vibration and offset during operation of the magnetic powder clutch; and the rigid connection between the motor and the clutch ensures the accuracy of dynamic tension control.

[0029] In this embodiment, preferably, multiple sets of doors 115 are bolted to the four sides of the box body 111, and heat dissipation grooves 116 are respectively opened on the two side doors 115 of the box body 111.

[0030] The above scheme enables omnidirectional maintenance of the transmission mechanism through multiple sets of doors bolted around the enclosure; heat convection between the magnetic powder clutch and the motor is guided by heat dissipation slots opened in specific doors; and the electromagnetic control system is maintained in a long-term stable operation through a controllable heat dissipation path.

[0031] In this embodiment, a low-voltage cable drawing machine is used such that the cable wire first enters from below the radial outer side of the first set of rotating wheels 109, spirals up along the wheel surface to the top, and then exits from above the radial outer side. It then enters the drawing hole 106 in the center of the first mold 105 for initial stretching and diameter reduction. Since the height of the rotating wheels 109 increases sequentially, this configuration is achieved by gradually raising the height of the lifting platforms 118 at the top of the second and third sets of assembly plates 107. The base height of the first set of assembly plates 107 is relatively low, ensuring that the cable wire can transition naturally between adjacent rotating wheels 109 without overlapping, thus improving system stability and operational continuity. Next, the cable wire flows to the next rotating wheel 109. At 09:00, this entry and exit path is repeated, guided by a second set of taller rotating wheels 109, and then into the second mold 105 for secondary wire drawing. During this stage, the height of the mold 105 increases sequentially, while the diameter of the matching wire drawing holes 106 decreases sequentially, ensuring that the cable wire gradually thins and forms a uniform shape during multi-stage stretching, effectively preventing stress concentration or breakage of the material during continuous deformation. In the entire system, each assembly platform 104 serves as a support platform for the mold 105, sliding within the sliding groove 102 on the slide table 101 using sliding blocks 103. This allows for easy adjustment of the position of the assembly platform 104 via bolts, thereby flexibly controlling the angle of the mold 105. This angle adjustment is crucial. Especially when changing to different models of mold 105 or stretching cable wires of different diameters, it ensures that the cable wire inlet direction is accurately aligned with the center line of the wire drawing hole 106, effectively avoiding unnecessary friction or scratching between the cable wire and the external structure of mold 105 (such as the inlet conical surface). At the same time, this design not only simplifies the replacement and maintenance process of mold 105, but also allows for rapid parameter adjustment for different cable specifications, significantly improving production adaptability and efficiency. The drive of the rotating wheel 109 is powered by an electric motor 114, whose output end is connected to the shaft of the magnetic powder clutch 112, driving the rotating shaft 110 to rotate. The rotating shaft 110 extends into the housing 111 and is connected to the rotor end of the magnetic powder clutch 112. The support base of 2 is fixed to the bottom of the support platform 108, which is fixedly installed on the top of the housing 111, forming a compact and stable transmission structure. The magnetic powder clutch 112 plays a key role here, controlling the torque and speed transmitted at the rotor end through the current of the magnetic powder medium, thereby finely adjusting the rotation speed of the rotating wheel 109 or the tension applied to the cable wire, and avoiding slippage or breakage during the stretching process. The motor 114 is bolted to the support base of the magnetic powder clutch 112 through the connecting plate 117, ensuring the stability of the drive and the installation accuracy. In the overall layout of the equipment, the housing 111 serves as the basic frame, and the support legs 113 at its bottom provide grounding support, ensuring that the entire system does not vibrate or shift during high-load operation.The cabinet 111 has doors 115 bolted around its perimeter, facilitating inspection and maintenance of internal components. Some doors 115 feature heat dissipation grooves 116 that effectively guide internal heat out, preventing performance degradation due to overheating of the magnetic powder clutch 112 or motor 114, extending equipment lifespan and maintaining efficiency. The cable wire continuously flows through rotating wheels 109 and dies 105, undergoing progressive diameter reduction before finally outputting a fine wire of the required specifications. The entire process achieves high component synergy: rotating wheels 109 provide a smooth conveying path, dies 105 perform continuous diameter reduction, the magnetic powder clutch 112 applies precise control, and the assembly table 104's angle adjustment function supports rapid and accurate die changes and wiring, comprehensively improving the wire drawing machine's production efficiency, finished product quality, and ease of operation.
