Description

Technical Field

[0001] This utility model relates to the field of cable production, and in particular to a high-speed cable drawing machine. Background Technology

[0002] In the field of metal conductor processing, the drawing and forming of metal wires typically relies on multi-stage drawing mechanisms to achieve continuous diameter reduction and surface quality control. Traditional drawing equipment mostly uses fixed dies to extrude and form metal wires. However, during long-term high-speed drawing, the dies are prone to wear due to hard contact, leading to changes in the diameter of the dies. This results in a decrease in the dimensional accuracy of the formed metal wire and the generation of scratches in localized areas, affecting the stability of subsequent processes.

[0003] To reduce forming defects caused by die wear, some equipment has begun to adopt a wheel-type wire drawing structure. However, existing wheel-type wire drawing equipment generally relies on a wire drawing wheel in a fixed position to press the metal wire together, resulting in low precision in adjusting the bonding pressure. This makes it difficult to maintain a stable bonding pressure during high-speed continuous production, leading to uneven deformation of the metal wire surface. Furthermore, existing equipment typically requires shutdown when the wire drawing wheel needs to be replaced or local maintenance is required, causing production interruptions and impacting overall capacity. Utility Model Content

[0004] The purpose of this utility model is to propose a high-speed cable drawing machine to solve the traditional problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-speed cable drawing machine unit, including a base and two drawing components movably connected thereon, the base including a fixed frame and a main beam fixed thereon, and a hydraulic rod installed on the inner wall of the fixed frame; The wire drawing assembly includes a balance frame movably connected to one end of the main beam. Wire drawing wheels are rotatably mounted at both ends of the balance frame. A pressure frame is movably mounted on the balance frame. An adjusting screw that is threadedly connected to the balance frame slides through the pressure frame. The end of the pressure frame is movably connected to a movable plate driven by a hydraulic rod.

[0006] As a further description of the above technical solution: the end of the hydraulic rod is fixed with an end frame, and the end frame is movably connected to the opposite ends of the two movable plates.

[0007] As a further description of the above technical solution: the base also includes a detector located on one side of the fixing frame to detect the wire drawing diameter.

[0008] As a further description of the above technical solution: the pressure frame has a strip-shaped through hole, the adjusting screw slides through the through hole, and one side of the pressure frame is hinged to the balance frame.

[0009] As a further description of the above technical solution: a rubber washer is fitted on the adjusting screw, and the adjusting screw is installed perpendicular to the balance frame.

[0010] As a further description of the above technical solution: the arc-shaped sidewall of the wire drawing wheel is provided with meshing texture, and the groove of the sidewall of the wire drawing wheel is polished.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This solution uses a hydraulic rod to drive the end frame and simultaneously move two movable plates together. When the movable plates are in a vertically aligned state, the pressure frame pryes the balance frame, achieving synchronous tightening of the first set of wire drawing wheels. This creates a stable and controllable extrusion forming force when the metal wire passes through, significantly reducing the wear risk caused by traditional die hard extrusion and effectively improving the surface finish of the metal wire.

[0012] The adjusting screw can limit the maximum deflection angle of the pressure frame, keeping the contact pressure of the drawing wheel constant within the set range. This can compensate for minor fluctuations in wire diameter during high-speed drawing, ensuring consistency in metal properties and dimensions.

[0013] As the hydraulic rod continues to extend, the movable plate generates a reverse pulling force, causing the pressure frame to drive the balance frame to deflect to the other side. This allows the second set of drawing wheels to smoothly engage and automatically separates from the first set of drawing wheels, achieving seamless switching of the drawing wheel sets. Worn drawing wheels can be maintained or replaced in the separated state without machine downtime, significantly improving continuous production capacity. This solution achieves a drawing operation mode with controllable pressure, smooth switching, and uninterrupted maintenance, reducing production losses and improving overall processing efficiency.

[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] like Figure 1 - Figure 4 As shown, the present invention provides a high-speed cable drawing machine unit, including a base 1 and two drawing components 2 movably connected thereon. The base 1 includes a fixed frame 11 and a main beam 12 fixed thereon. A hydraulic rod 13 is installed on the inner wall of the fixed frame 11. The wire drawing assembly 2 includes a balance frame 21 movably connected to one end of the main beam 12. Wire drawing wheels 24 are rotatably installed at both ends of the balance frame 21. A pressure frame 22 is movably installed on the balance frame 21. An adjusting screw 26, which is threadedly connected to the balance frame 21, slides through the pressure frame 22. The end of the pressure frame 22 is movably connected to a movable plate 23 driven by a hydraulic rod 13.

[0018] This solution uses a hydraulic rod 13 to synchronously drive two movable plates 23 via an end frame 14 to achieve synchronous force distribution. This allows the pressure frame 22 to pry the balance frame 21 with a controllable lever action, thereby enabling the first set of drawing wheels 24 to apply a stable and controllable bonding force to the metal wire. The metal wire is extruded and shaped under the cooperation of the meshing texture of the drawing wheels 24 and the polishing groove surface, significantly reducing the risk of wear and scratches caused by the hard contact of traditional die, and improving the surface finish and dimensional consistency of the drawn wire. The adjusting screw 26 limits the maximum deflection angle of the pressure frame 22, which can accurately limit the bonding pressure and compensate for small fluctuations in wire diameter, achieving stability and repeatability of the bonding force. The added detector 15 enables real-time monitoring of the drawn wire diameter, providing timely feedback for quality control, thereby reducing the defect rate and improving the yield rate. As the hydraulic rod 13 continues to extend, the system applies force in the opposite direction to deflect the balance frame 21 to the other side, allowing the second set of drawing wheels 24 to smoothly engage and complete the drawing operation. At the same time, the first set of drawing wheels 24 is opened for maintenance or replacement, thus supporting wheel group maintenance without interrupting the main production line, significantly reducing downtime and improving production continuity. The balanced force design of the overall structure and the adjustable engagement force improve the process stability under high-speed operation, extend the service life of the drawing wheels 24, reduce maintenance frequency, improve production efficiency, and enhance the consistency and reliability of the processed products.

[0019] Specifically, such as Figure 2As shown, the end of the hydraulic rod 13 is fixed with an end frame 14, and the end frame 14 is movably connected to the opposite ends of the two movable plates 23.

[0020] By setting up end frame 14, end frame 14 serves as a transfer mechanism, enabling simultaneous coordinated connection and transmission of two movable plates 23.

[0021] Specifically, such as Figure 4 As shown, the base 1 also includes a detector 15 located on one side of the fixing frame 11 to detect the wire drawing diameter.

[0022] By setting up detector 15, the diameter of the wire can be detected, and the detection data can be fed back to the industrial control computer, thereby controlling the pressure control of hydraulic rod 13 in coordination.

[0023] Specifically, such as Figure 3 As shown, the pressure frame 22 has a strip-shaped through hole 25, and the adjusting screw 26 slides through the through hole 25. One side of the pressure frame 22 is hinged to the balance frame 21.

[0024] By providing a through hole 25, which is formed on the pressure frame 22, the adjusting screw 26 can be kept within tolerance when the pressure frame 22 is deflected, thereby reducing motion interference.

[0025] Specifically, such as Figure 3 As shown, a rubber washer is fitted on the adjusting screw 26, and the adjusting screw 26 is installed perpendicular to the balance frame 21.

[0026] By setting rubber washers, rigid wear between the pressure frame 22 and the adjusting screw 26 is avoided when the pressure frame 22 deflects, and the adjusting screw 26 pulls the balance frame 21 to deflect.

[0027] Specifically, such as Figure 1 As shown, the arc-shaped sidewall of the wire drawing wheel 24 is provided with meshing texture, and the groove of the sidewall of the wire drawing wheel 24 is polished.

[0028] The meshing texture of the drawing wheel 24 enhances the consistency of its rotation, improves the quality of drawing, and the polishing of the inner wall keeps it smoother and reduces friction.

[0029] When this solution is in use, the extension of the hydraulic rod 13 causes the hydraulic rod 13 to move along with the two movable plates 23 through the end frame 14. When the two movable plates 23 are parallel and vertical to each other, they pry the balance frame 21 through the pressure frame 22 to deflect it, so that the wire drawing wheels 24 at one end of the two balance frames 21 are tightly attached, and the metal wire passes through the two wire drawing wheels 24 and is squeezed into shape. This method, through the cooperation of the drawing wheel 24, can perform preliminary drawing of the metal wire, greatly reducing the decrease in precision caused by wear in traditional hole drawing. Furthermore, this solution controls the maximum deflection angle of the pressure frame 22 by rotating the adjusting screw 26, adapting to the vertical state of the movable plate 23 to complete the fit of a pair of wire drawing wheels 24, which can easily adapt to the existence of errors; As the hydraulic rod 13 continues to extend, the movable plate 23 begins to pull the pressure frame 22. Under the action of tension, the pressure frame 22 pulls the balance frame 21 to deflect to the other side, so that its other pair of wire drawing wheels 24 come into contact. The original wire drawing wheels 24 are separated for maintenance or replacement, realizing continuous production maintenance without stopping the machine.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
