Description

Technical Field

[0001] This utility model relates to the field of wire drawing machine technology, and in particular to a wire drawing machine for aluminum wire. Background Technology

[0002] Aluminum alloy wire is a commonly used conductive wire with low resistance, high strength, and high toughness. It is a new type of high-voltage wire material. The aluminum wire produced in the factory has a fixed size. If it is necessary to make it into conductors of different sizes, the original aluminum wire needs to be drawn. Wire drawing requires drawing equipment.

[0003] Existing wire drawing equipment has the following shortcomings in practical use: On the one hand, a large amount of wire drawing debris is generated during the wire drawing process, which requires regular manual cleaning. This is labor-intensive, and the accumulated debris will have a certain negative impact on the wire drawing operation. On the other hand, when the wire passes through the wire drawing die, a large amount of heat is generated due to plastic deformation and friction. If the heat cannot be dissipated in time, it will not only affect the processing quality of the aluminum wire and cause problems such as oxidation and deformation on the surface of the aluminum wire, but also accelerate the wear of the wire drawing die and reduce the service life of the wire drawing die. Utility Model Content

[0004] In order to address the technical deficiencies mentioned in the background, the purpose of this utility model is to provide a wire drawing machine for aluminum wires, which achieves precise spraying and cooling of aluminum wires during the wire drawing process by setting a coolant spraying device in the wire drawing area, thereby improving the processing effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The winding and unwinding device includes an unwinding drum and a winding drum. The unwinding drum is vertically positioned at one end of the frame, and the winding drum is horizontally positioned at the other end of the frame. A wire guide device and a wire drawing device are positioned between the unwinding drum and the winding drum. The wire guide device is located on both sides of the wire drawing device and is used to guide the aluminum wire through the wire drawing device sequentially along a predetermined path. A power transmission device is connected to one end of the wire guide device and the winding drum. A coolant spray device is positioned above the wire guide device and is used to spray coolant onto the aluminum wire in the processing state. The spray nozzle of the coolant spray device faces the contact area between the aluminum wire and the wire guide device, and the coolant spray device is connected to an external coolant supply source through a pipe.

[0009] Preferably, the waste collection device includes a liquid collection tank, a collection trough disposed on the top of the liquid collection tank, and a drain outlet connecting the liquid collection tank and the collection trough. The liquid collection tank is disposed below the wire drawing device and the wire guiding device. Baffles are provided around the perimeter of the collection trough. The drain outlet is disposed at the bottom of the collection trough, and the collected waste liquid or waste debris is centrally processed through the drain outlet.

[0029] The following is in conjunction with the appendix Figure 1-7 The present invention provides a more detailed description of an embodiment of an aluminum wire drawing machine.

[0030] A wire drawing machine for aluminum wire, such as Figures 1 to 4 As shown, the device includes a frame 1, on which a winding and unwinding device 2 for unwinding and rewinding aluminum wire is installed. The winding and unwinding device 2 includes an unwinding drum 21 and a winding drum 22. The unwinding drum 21 is vertically arranged at one end of the frame 1, and the winding drum 22 is horizontally arranged at the other end of the frame 1. A wire guide device 3 and a wire drawing device 4 are arranged between the unwinding drum 21 and the winding drum 22. The wire guide device 3 is located on both sides of the wire drawing device 4 and is used to guide the aluminum wire through the wire drawing device 4 sequentially along a predetermined path. A power transmission device 5 is connected to one end of the wire guide device 3 and the winding drum 22. A coolant spray device 6 is arranged above the wire guide device 3. The coolant spray device 6 is used to spray coolant onto the aluminum wire in the processing state. The spray nozzle of the coolant spray device 6 faces the contact area between the aluminum wire and the wire guide device 3, and the coolant spray device 6 is connected to an external coolant supply source through a pipe.

[0031] Specifically, the unwinding and winding devices 2 are positioned horizontally and vertically at both ends of the frame 1, respectively. They stably release the aluminum wire to be processed and orderly wind up the finished product. Together with the wire guide device 3, they form a continuous wire transport path, ensuring the aluminum wire maintains a stable direction during the drawing process. The wire guide device 3, located on both sides of the drawing device 4, not only provides precise guidance for the aluminum wire, but its power transmission device 5, connected to one end of the winding drum 22, also provides continuous and adaptable power for the entire wire transport process, ensuring stable tension required for drawing. The coolant spray device 6, located above the wire guide device 3, is connected to an external coolant supply source via pipes. Its spray nozzles are directly directed towards the contact area between the aluminum wire and the wire guide device 3, allowing for real-time spraying of coolant during aluminum wire processing. This specifically cools the area where frictional heat is generated between the aluminum wire and the guide device, while also providing lubrication. This reduces oxidation and deformation of the aluminum wire surface caused by high temperatures and also reduces wear on the guide components.

[0032] This overall structural layout ensures a smooth and orderly process for aluminum wire from unwinding, guiding, drawing to cooling and rewinding. The components work together seamlessly, solving the problem of heat dissipation in existing wire drawing equipment. The rational component layout also ensures the stability and continuity of aluminum wire processing, effectively improving the processing quality and equipment operating efficiency. It reduces processing defects caused by manual intervention or unreasonable equipment layout. The overall structure is compact and highly functional, making it suitable for the large-scale, high-quality aluminum wire drawing processing needs.

[0033] In this embodiment, as Figure 7 As shown, the coolant spraying device 6 includes a mounting bracket 61, spray pipes 62, and spray heads 63. The mounting bracket 61 has an L-shaped hollow structure, with its bottom fixed to the frame 1, serving to support and position components such as the spray pipes 62. The hollow structure can conceal some pipes, making the equipment look cleaner. The spray pipes 62 are located at the bottom of the mounting bracket 61 and extend along the length of the mounting bracket 61, providing a channel for coolant delivery. The spray heads 63 are evenly distributed on the spray pipes 62, and each spray head 63 has spray holes 631, enabling the coolant to be sprayed evenly.

[0034] Specifically, the spray pipe 62 and spray head 63 are stably installed by the L-shaped mounting bracket 61 to ensure accurate spraying position; the equidistantly distributed spray heads 63 ensure that the coolant evenly covers the aluminum wire processing area, effectively removing heat and reducing the risk of surface oxidation and deformation of the aluminum wire due to high temperature. At the same time, the lubrication effect reduces the friction between the aluminum wire and the wire guide device 3 and the wire drawing device 4, delays mold wear, improves the aluminum wire processing quality and mold life, and also reduces the problem of processing affected by debris accumulation; the external coolant supply source delivers coolant to the channel in the mounting bracket 61 through the pipeline (or directly connects to the spray pipe 62). After the coolant enters the spray pipe 62, it is sprayed through the spray holes 631 of the spray head 63 onto the contact area between the aluminum wire and the wire guide device 3 in the processing state, cooling and lubricating the aluminum wire and the wire guide device 3, removing the heat generated by wire drawing, and washing away any debris that may be generated.

[0035] It should be noted that the coolant used in this coolant spraying device is a common material in existing machining processes, and its temperature range and flow control method are common knowledge, so they will not be described in detail.

[0036] In this embodiment, as Figure 1 As shown, the waste collection device includes a liquid collection tank 71, a collection trough 72, and a drain outlet 73. The liquid collection tank 71 is located below the wire drawing device 4 and the wire guiding device 3 and is used to store the collected waste liquid or waste debris. The collection trough 72 has an opening at the top and baffles 721 around its perimeter to prevent waste liquid or waste debris from overflowing and to ensure the effectiveness of collection. The drain outlet 73 is located at the bottom of the collection trough 72 and connects the liquid collection tank 71 and the collection trough 72, serving as a channel for the discharge of waste liquid or waste debris.

[0037] Specifically, when the wire drawing device 4 is working, the wire drawing debris and the waste liquid that flows down after being sprayed by the coolant spray device 6 will fall into the collection tank 72 below. Since the collection tank 72 is blocked by the baffle 721, the waste liquid and debris remain in the collection tank 72, and then flow into the liquid collection tank 71 through the drain port 73 for temporary storage. Subsequently, the waste liquid or debris in the liquid collection tank 71 can be centrally treated through the drain port 73, such as periodically extracting and filtering coolant.

[0038] It is worth noting that the baffle 721 of the collection tank 72 is designed to effectively prevent waste liquid and debris from scattering everywhere, ensuring a clean working environment; the collection tank 71 centrally stores the liquid for easy subsequent unified processing, reduces the labor intensity of manual cleaning, reduces the negative impact of debris accumulation on wire drawing operations, and can also recycle the coolant, thereby effectively saving costs.

[0039] In this embodiment, as Figure 5As shown, the wire guiding device 3 includes at least two sets of drawing roller groups 31. The drawing roller groups 31 are arranged on both sides of the drawing device 4, and multiple annular grooves 32 are evenly distributed along the axial direction on the surface of the drawing roller groups 31. The diameter of the annular grooves 32 increases from the near end to the far end along the axis of the drawing roller 31. This structure of the drawing roller group 31 can adapt to the changes in aluminum wire diameter at different processing stages and guide the aluminum wire to wind and transport in an orderly manner.

[0040] Specifically, after the aluminum wire is released from the unwinding drum 21, it enters the annular groove 32 of the drawing roller assembly 31. As the drawing process progresses, the diameter of the aluminum wire gradually decreases. This design adapts to the characteristic that the groove diameter gradually increases from the inside to the outside, or selects a suitable groove based on the actual wire feeding path. Through the rotation of the drawing roller assembly 31, combined with the power provided by the power transmission device 5, the aluminum wire is guided to pass through the drawing device 4 sequentially along a predetermined path, providing tension to the aluminum wire and ensuring stable drawing. The design of multiple drawing roller assemblies 31 and annular grooves 32 with different diameters can precisely guide the aluminum wire feeding path, adapt to the diameter changes during the drawing process, ensure stable tension of the aluminum wire during drawing, avoid aluminum wire deviation and vibration, improve the accuracy and stability of the drawing process, and make the aluminum wire processing quality more reliable.

[0041] In this embodiment, as Figure 6 As shown, the wire drawing device 4 includes a straightening bracket 41 and wire drawing die blocks 42. The straightening bracket 41 is fixed on the frame 1 and has a mounting groove 411 for mounting the wire drawing die blocks 42. The wire drawing die blocks 42 are arranged linearly in the mounting groove 411, and each wire drawing die block 42 has a die hole 421 in its center. The diameter of the die holes 421 is different, which is used to gradually draw and reduce the diameter of the aluminum wire. In addition, slots 412 for straightening the aluminum wire are provided on both sides of the straightening bracket 41, and the slots 412 correspond to the positions of the die holes 421.

[0042] Specifically, the aluminum wire first passes through the slots 412 on both sides of the straightening bracket 41, where the slots 412 initially straighten the aluminum wire. Then, the aluminum wire enters the die holes 421 of the linearly arranged wire drawing die blocks 42. As the diameter of the die holes 421 gradually decreases, the aluminum wire undergoes plastic deformation under tension as it passes through the die holes 421, and its diameter is gradually thinned, thus achieving the wire drawing process. The slots 412 of the straightening bracket 41 first straighten the aluminum wire, ensuring the straightness of the aluminum wire when it enters the wire drawing die blocks 42, and improving the wire drawing accuracy. The linearly arranged wire drawing die blocks 422 with different die hole diameters can gradually reduce the diameter of the aluminum wire, making the deformation of the aluminum wire more uniform, avoiding excessive deformation in a single step that could lead to aluminum wire breakage or quality problems, and improving the processing quality and yield of the aluminum wire.

[0043] In this embodiment, as Figure 4As shown, the power transmission device 5 includes a drive motor 51, a reducer 52, and a pulley assembly 53. The drive motor 51 is mounted on the frame 1, and its output end is connected to the reducer 52 for transmission. The reducer 52 is used to adjust the speed and torque. The pulley assembly 53 is respectively mounted on one end of the winding drum 22 and the drawing roller group 31, and is linked to the reducer 52 to realize power transmission.

[0044] Specifically, the drive motor 51 starts and outputs power, which is transmitted to the reducer 52. After the reducer 52 adjusts the speed and torque of the power, it transmits the power to the unwinding drum 21 and the wire drawing roller group 31 through the belt pulley assembly 53. The wire drawing roller group 31 is driven to rotate to guide the aluminum wire to feed, and the take-up drum 22 is driven to rotate to realize the take-up of the aluminum wire, so that the power transmission of the entire wire drawing process is stable and controllable.

[0045] It is worth noting that the control device 8 is installed on the upper part of the frame 1 and is electrically connected to the power transmission device 5 and the coolant spray device 6 respectively. Through internal controllers, operation buttons, and displays, it enables the setting and adjustment of equipment operating parameters and the monitoring of operating status. Operators use the control device 8 to set the operating parameters of the power transmission device 5, the spray volume of the coolant spray device 6, and the spraying timing. The control device 8 receives real-time operating status signals (such as motor current and spray pressure) from the power transmission device 5 and the coolant spray device 6. When abnormalities occur (such as overload or insufficient spraying), it can issue commands to perform alarms, adjust operating parameters, or shut down the machine.

[0046] The working principle of this utility model:

[0047] When the aluminum wire drawing machine is working, the unwinding drum 21 horizontally releases the aluminum wire raw material, the drive motor 51 in the power transmission device 5 starts, the speed and torque are adjusted by the reducer 52, and then the power is transmitted to the unwinding drum 21 and the drawing roller group 31 by the belt pulley assembly 53. The aluminum wire is first initially straightened by the slots 412 on both sides of the straightening bracket 41, and then enters the drawing die block 42 with linear arrangement and gradually changing diameter of the die hole 421. Under the tension, the diameter is gradually reduced to complete the drawing. The winding drum 22 rotates vertically to wind up the finished aluminum wire. At the same time, the coolant spraying device 6 sprays coolant into the contact area between the aluminum wire and the wire guide device 3 through the spray pipe 62 and spray head 63 on the mounting bracket 61. While cooling and lubricating, it can also wash away the debris. The generated waste debris and waste liquid fall into the collection tank 72 of the waste collection device 7 below, and enter the collection tank 71 through the drain port 73 for centralized treatment. The control device 8 monitors and adjusts equipment parameters throughout the process, enabling coordinated unwinding, wire drawing, cooling, and winding to achieve stable and efficient aluminum wire processing, improve quality and efficiency, ensure equipment stability, and reduce operating costs.

[0048] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
