Description

Technical Field

[0001] This invention relates to the field of metal wire processing technology, and more specifically, to a high-speed metal wire drawing machine. Background Technology

[0002] In high-speed metal wire drawing, after being plastically deformed by drawing, the metal wire enters the cooling tank at a high temperature (typically above 300°C). Its surface heat needs to be rapidly dissipated through forced convection with the cooling liquid to prevent grain coarsening, surface oxidation, or lubricant film failure. Since the heat flux density is highest at the die exit and gradually decreases along the travel direction due to continuous heat dissipation, the ideal cooling intensity should match this heat load distribution. That is, the inlet area needs strong agitation to quickly break the thermal boundary layer, while the outlet area only needs to maintain basic circulation to prevent the cooled liquid from being re-entrained into the high-temperature zone or causing surface splashing. However, existing wire drawing machine cooling tanks generally use a single motor to synchronously drive multiple stirring rods via a rigid shaft or equal-diameter pulleys, resulting in uniform stirring intensity across all areas, which cannot adapt to gradient changes in heat load. Insufficient agitation at the inlet causes localized overheating, affecting the mechanical properties of the wire. At the outlet, unnecessary high-speed agitation exacerbates liquid splashing, polluting the equipment environment and increasing pumping energy consumption. To achieve variable-speed agitation, some solutions attempt to introduce multiple motors to control each agitator separately, but this leads to problems such as increased complexity of the control system, difficult wiring, more potential failure points, and higher costs. Other solutions use planetary gears or differential mechanisms, which can achieve single-input multi-output speed regulation, but have poor structural compactness, are difficult to arrange at the bottom of narrow cooling tanks, and once the internal gears are damaged, the entire machine needs to be shut down for disassembly and repair, resulting in low maintenance efficiency.

[0003] In addition, traditional stirring blades are mostly welded or bolted to the rotating shaft. When cleaning or replacing them, the coolant needs to be drained and the transmission components need to be disassembled, which seriously affects the continuity of production. Therefore, there is an urgent need for a cooling stirring device that relies on a single power source, outputs a stable gradient speed in a limited space through a purely mechanical means, and has a modular quick-disassembly structure, in order to solve the core problems of mismatch between cooling intensity and heat load, high system complexity and inconvenient maintenance in the existing technology. Summary of the Invention

[0004] This invention proposes a high-speed metal wire drawing machine, which solves the technical problem of mismatch between cooling effect and heat load distribution caused by the use of a single rotation speed in the existing cooling tank stirring system; In actual wire drawing, the temperature of the wire decreases from high to low along the direction of travel after exiting the die. However, in traditional structures, multiple stirring rods operate synchronously at the same speed, resulting in insufficient disturbance and low heat dissipation efficiency in the inlet area, and excessive stirring in the outlet area causing liquid splashing and wasting energy. Furthermore, the stirring components are mostly integrally welded or bolted, requiring machine shutdown for drainage and disassembly of transmission components for maintenance, making the process cumbersome. This invention uses a single motor to drive a gear and a synchronous toothed belt, utilizing pulleys with different tooth diameters to achieve gradient speeds for three sets of stirring rods. The stirring blades employ a quick-release structure with a limit rod and spring return, allowing for rapid replacement or cleaning without disassembling the entire machine, effectively improving cooling uniformity, operational stability, and ease of maintenance.

[0005] According to one aspect, at least one embodiment of the present invention provides a high-speed metal wire drawing machine, comprising: a drawing machine body, on which a metal wire body is disposed, a motor fixedly connected to the bottom end of one end of the drawing machine body, a first transmission gear fixedly connected to the output end of the motor, a second transmission gear meshing with one end of the first transmission gear, a first toothed pulley fixedly connected to one end of the second transmission gear, a synchronous toothed belt drivingly disposed on the outer wall of the first toothed pulley, a second toothed pulley drivingly disposed on the synchronous toothed belt, a third toothed pulley drivingly disposed on the synchronous toothed belt, and a rotating shaft fixedly connected to the bottom end of the drawing machine body inside an immersion tank through the first toothed pulley, and a stirring rod fixedly connected to the top end of the rotating shaft.

[0006] For example, at least one embodiment of the present invention provides a high-speed metal wire drawing machine, which further includes: a first toothed pulley, a second toothed pulley and a third toothed pulley arranged side by side at the bottom of the drawing machine body, wherein the tooth diameter of the first toothed pulley is smaller than that of the second toothed pulley, and the tooth diameter of the second toothed pulley is smaller than that of the third toothed pulley.

[0007] For example, at least one embodiment of the present invention provides a high-speed metal wire drawing machine, which further includes: a connecting column inserted inside the stirring rod, a first stirring blade fixedly connected to the top of the connecting column, a connecting rod fixedly connected to the top of the connecting column, a second stirring blade fixedly connected to the top of the connecting rod, and a top plate fixedly connected to the top of the connecting rod.

[0008] For example, at least one embodiment of the present invention provides a high-speed metal wire drawing machine, which further includes: the first stirring blade is spirally disposed outside the connecting rod, and the first stirring blade is symmetrically disposed.

[0009] For example, at least one embodiment of the present invention provides a high-speed metal wire drawing machine, which further includes: four sets of second stirring blades are provided on the connecting rod, and the second stirring blades are disposed above the connecting rod.

[0010] For example, at least one embodiment of the present invention provides a high-speed metal wire drawing machine, which further includes: a first slot is provided inside the stirring rod, the bottom end of the connecting column is inserted into the first slot, a moving groove is provided inside the connecting column, a limiting rod is movably disposed inside the moving groove, an auxiliary groove is provided on the side of the moving groove, a second slot is provided inside the stirring rod, the limiting rod passes through the auxiliary groove and is inserted into the second slot, and a moving column is movably disposed inside the second slot.

[0011] For example, at least one embodiment of the present invention provides a high-speed metal wire drawing machine, which further includes: a second spring disposed inside the moving groove, one end of the second spring being fixedly connected to a limiting rod, the other end of the second spring being fixedly connected to the moving groove, and a first spring disposed inside the second mounting slot.

[0012] For example, at least one embodiment of the present invention provides a high-speed metal wire drawing machine, which further includes: the moving column and the limiting rod corresponding to each other, and the outer wall of the limiting rod and the inner wall of the auxiliary groove being in contact with each other.

[0013] For example, at least one embodiment of the present invention provides a high-speed metal wire drawing machine, which further includes: four sets of second stirring blades arranged alternately along the circumference of the connecting rod, wherein two sets of adjacent blades have an included angle of 80° and the other two sets have an included angle of 100°, and the included angles of 80° and 100° alternate.

[0014] For example, at least one embodiment of the present invention provides a high-speed metal wire drawing machine, which further includes: the outer wall of the moving column is provided with anti-slip texture, and the outer wall of the moving column is in contact with the inner wall of the second mounting slot.

[0015] The working principle and beneficial effects of this invention are as follows: This application uses a motor to drive the first transmission gear and the second transmission gear to mesh, transmitting the rotational motion to the first toothed pulley, and then the synchronous toothed belt synchronously drives the second toothed pulley and the third toothed pulley to rotate. Since the tooth diameters of the three increase sequentially, according to the belt drive principle, the rotational speed of the stirring rod connected to each pulley decreases accordingly, thereby forming a gradient stirring mode with fast inlet and slow outlet. This allows the high-temperature zone to be sufficiently disturbed to enhance heat transfer, while the low-temperature zone reduces the stirring intensity to suppress splashing and reduce ineffective energy consumption.

[0016] The stirring assembly adopts a split structure. The connecting column is inserted into the first slot at the top of the stirring rod, and the axial locking is achieved by the limiting rod passing laterally into the second slot on the side wall of the stirring rod. When the exposed moving column is pressed, the limiting rod retracts against the elastic force of the second spring and disengages from the second slot, so that the connecting column, together with the first stirring blade, the second stirring blade and the top plate, can be quickly pulled out without disassembling the transmission system or draining the coolant, which significantly improves maintenance efficiency.

[0017] The first stirring blade is arranged in a symmetrical spiral shape outside the connecting rod. When rotating, it pushes the cooling liquid to flow along the axial direction, promoting the exchange of liquid between the upper and lower layers. The second stirring blade is set in four groups and distributed circumferentially with alternating angles of 80° and 100°. This breaks the periodicity of the blade passing frequency, weakens the flow field resonance, and at the same time forms an asymmetric vortex in the horizontal plane, enhancing the uniformity of lateral mixing.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] Refer to the instruction manual appendix Figure 1-6A high-speed metal wire drawing machine includes a drawing machine body 1, on which a metal wire body 2 is mounted. The metal wire body 2 travels horizontally along the length of the drawing machine body 1 to complete drawing and subsequent cooling. A motor 4 is fixedly connected to one bottom end of the drawing machine body 1, providing rotational driving force as a power source. A first transmission gear 5 is fixedly connected to the output end of the motor 4, coaxially fixed with the output shaft of the motor 4, and rotates synchronously with the motor 4. A second transmission gear 6 is meshed with one end of the first transmission gear 5, receiving the rotational motion from the first transmission gear 5 through gear meshing and changing the transmission direction or speed. One end of the second transmission gear 6 is fixedly connected to the first toothed pulley 7. The first toothed pulley 7 and the second transmission gear 6 are coaxially mounted and rotate synchronously. The outer wall of the first toothed pulley 7 is provided with a synchronous toothed belt 8, which is a closed ring belt. Its inner side is provided with a toothed structure that matches the pulley to ensure no slippage during transmission. The synchronous toothed belt 8 is provided with a second toothed pulley 9 and a third toothed pulley 10. The second toothed pulley 9 and the third toothed pulley 10 are located at different positions on the synchronous toothed belt 8, forming a multi-path parallel transmission through the synchronous toothed belt 8 and the first toothed pulley 7. The first toothed pulley 7 passes through the bottom of the drawing machine body 1 and is fixedly connected to a rotating shaft 11 inside the immersion tank 3. The rotating shaft 11 is vertically arranged, with its upper end fixedly connected to the first toothed pulley 7 and its lower end extending into the immersion tank 3. A stirring rod 12 is fixedly connected to the top of the rotating shaft 11. The stirring rod 12 rotates synchronously with the rotating shaft 11 to stir the cooling liquid in the immersion tank 3.

[0027] In the above operation, when the wire drawing machine body 1 is running, the motor 4 starts and drives the first transmission gear 5 to rotate. The first transmission gear 5 drives the second transmission gear 6 to rotate through gear meshing. The second transmission gear 6 drives the first toothed pulley 7 to rotate synchronously. The first toothed pulley 7 transmits power to the second toothed pulley 9 and the third toothed pulley 10 through the synchronous toothed belt 8, so that the two rotate simultaneously. Since the first toothed pulley 7, the second toothed pulley 9 and the third toothed pulley 10 are respectively connected to three independent rotating shafts 11, the three sets of stirring rods 12 rotate accordingly. Because the diameters of each pulley are different, the three sets of stirring rods 12 obtain different speeds, thereby realizing the gradient stirring of the cooling liquid inside the immersion tank 3 from strong to weak, meeting the cooling needs of the metal wire body 2 at different positions.

[0028] Then, the first toothed pulley 7, the second toothed pulley 9, and the third toothed pulley 10 are arranged side by side at the bottom of the wire drawing machine body 1. The tooth diameter of the first toothed pulley 7 is smaller than that of the second toothed pulley 9, and the tooth diameter of the second toothed pulley 9 is smaller than that of the third toothed pulley 10. According to the belt drive principle, when the diameter of the driving pulley is the same, the larger the diameter of the driven pulley, the lower the output speed. Therefore, the stirring rod 12 corresponding to the first toothed pulley 7 near the inlet of the metal wire body 2 has the highest speed, the stirring rod 12 corresponding to the second toothed pulley 9 in the middle has a moderate speed, and the stirring rod 12 corresponding to the third toothed pulley 10 at the outlet has the lowest speed. This speed distribution matches the heat load distribution of the metal wire body 2 after it exits the mold from high to low, so that the high temperature area receives stronger cooling disturbance, the low temperature area avoids excessive agitation, improves the overall cooling uniformity, and reduces liquid splashing.

[0029] Subsequently, a connecting post 13 is inserted inside the stirring rod 12. The connecting post 13 is a vertical rod-shaped structure, with its lower end inserted into the stirring rod 12 and its upper end extending upward. A first stirring blade 14 is fixedly connected to the top of the connecting post 13, and the first stirring blade 14 is used to generate axial flow. A connecting rod 15 is fixedly connected to the top of the connecting post 13, and the connecting rod 15 is coaxially arranged with the connecting post 13, forming a support frame for the stirring blade. A second stirring blade 16 is fixedly connected to the top of the connecting rod 15, and the second stirring blade 16 is used to enhance transverse mixing. A top plate 17 is fixedly connected to the top of the connecting rod 15, and the top plate 17 closes the top of the connecting rod 15 to prevent impurities from entering the internal structure. The first stirring blade 14 is spirally arranged outside the connecting rod 15. The direction of rotation is consistent with the direction of stirring to drive the liquid to flow axially; the first stirring blade 14 is arranged symmetrically, that is, the spiral structure on the left and right sides is symmetrically distributed to ensure rotational balance; four sets of second stirring blades 16 are arranged on the connecting rod 15, and the four sets of second stirring blades 16 are evenly or non-uniformly distributed in the upper area of ​​the connecting rod 15 along the circumference; the four sets of second stirring blades 16 are arranged alternately along the circumference of the connecting rod 15, of which two sets have an adjacent angle of 80° and the other two sets have an adjacent angle of 100°, and the angles of 80° and 100° alternate; this non-uniform angular distribution breaks the periodicity of the flow field, reduces the vibration caused by the frequency of blade passage, and promotes the irregular flow of coolant in the horizontal plane, thereby improving mixing efficiency.

[0030] Next, a first mounting slot 18 is formed inside the stirring rod 12. The first mounting slot 18 is an axial blind hole located at the center of the top of the stirring rod 12. The bottom end of the connecting column 13 is inserted into the first mounting slot 18 to achieve initial positioning of the connecting column 13 and the stirring rod 12. A moving groove 19 is formed inside the connecting column 13. The moving groove 19 is a transverse through hole that penetrates the side wall of the connecting column 13. A limiting rod 21 is movably installed inside the moving groove 19. The limiting rod 21 can slide radially within the moving groove 19. An auxiliary groove 20 is formed on the side of the moving groove 19. The auxiliary groove 20 connects the moving groove 19 and the outer wall of the connecting column 13, providing a movement channel for the limiting rod 21. A second mounting slot 22 is formed inside the stirring rod 12. The mounting slot 22 is a radial blind hole that intersects perpendicularly with the first mounting slot 18. The limiting rod 21 passes through the auxiliary groove 20 and is inserted into the second mounting slot 22. When the limiting rod 21 is fully inserted into the second mounting slot 22, the connecting column 13 is locked inside the stirring rod 12 and cannot be axially removed. A movable column 23 is movably provided inside the second mounting slot 22. The movable column 23 protrudes from the outer wall of the stirring rod 12 and can be manually pressed. When the movable column 23 is pressed, it pushes the limiting rod 21 inward, causing it to disengage from the second mounting slot 22 and releasing the limiting on the connecting column 13. At this time, the connecting column 13 and the stirring blade assembly can be pulled out of the stirring rod 12 as a whole, achieving quick disassembly and facilitating cleaning or replacement of damaged parts.

[0031] Secondly, a second spring 25 is installed inside the movable slot 19. The second spring 25 is sleeved on the outer periphery of the limiting rod 21, with one end fixedly connected to the limiting rod 21 and the other end fixedly connected to the inner wall of the movable slot 19. A first spring 24 is installed inside the second mounting slot 22, located between the movable column 23 and the bottom of the second mounting slot 22. When the external force is released, the first spring 24 pushes the movable column 23 to reset, and the second spring 25 pushes the limiting rod 21 outward to reset, allowing it to re-insert into the second mounting slot 22 and return to the locked state. The two sets of springs work together to ensure that the device remains firmly connected during normal operation, and can be unlocked with simple operation when disassembly is required.

[0032] Finally, the movable column 23 and the limiting rod 21 correspond to each other and are aligned radially to ensure that pressing the movable column 23 can effectively transmit the thrust to the limiting rod 21. The outer wall of the limiting rod 21 fits against the inner wall of the auxiliary groove 20, limiting the swaying of the limiting rod 21 during movement, ensuring that it slides smoothly along the predetermined trajectory, avoiding jamming or deflection, and improving operational reliability and structural durability.

[0033] In addition, the immersion tank 3 is a closed water tank structure, which contains cooling liquid for rapid cooling of the high-temperature metal wire body 2; three sets of stirring rods 12 are arranged sequentially along the traveling direction of the metal wire body 2, corresponding to the inlet zone, the middle zone and the outlet zone respectively; the inlet zone has the strongest stirring intensity, which is used to quickly remove the concentrated heat generated when the metal wire body 2 is demolded; the middle zone maintains moderate disturbance to prevent local temperature rise; the outlet zone has weaker stirring to avoid re-entraining the liquid in the cooled area to the high-temperature area, and at the same time reduce splashing caused by liquid surface fluctuations; this staged stirring method adapts the cooling process to changes in heat load, avoiding uneven cooling or energy waste caused by traditional uniform stirring.

[0034] The entire transmission system is driven by a single motor 4, and power distribution is achieved through a combination of gears and synchronous toothed belts. The structure is compact, requiring no additional motor, thus reducing equipment costs and control complexity. The synchronous toothed belt 8 ensures that the rotational speed of each stirring rod 12 is stable and unaffected by load fluctuations. The stirring blade assembly adopts a modular design, and quick installation and removal are achieved through a limit rod 21 and a spring reset mechanism. Maintenance does not require disassembling the entire machine or draining water, thus shortening downtime. The combination of the first stirring blade 14 and the second stirring blade 16 takes into account both axial circulation and lateral mixing, improving the overall flow field uniformity. The top plate 17 prevents impurities in the coolant from falling into the top gap of the connecting rod 15, reducing the risk of blockage.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
