Description

Technical Field

[0001] This invention relates to the field of enameled aluminum wire processing technology, and in particular to an integrated continuous drawing and annealing enameled aluminum wire processing apparatus and process. Background Technology

[0002] The continuous processing of enameled wire and its conductor wires typically involves drawing, heat treatment (annealing / tempering), cooling and shaping, straightening and winding.

[0003] In the prior art, to improve production efficiency, there are existing equipment solutions that continuously combine wire drawing machines and annealing sections. For example, Chinese patent document CN110586677A describes a multi-head continuous annealing and wire drawing equipment, which achieves a combination of wire drawing and continuous annealing through multiple stations and transmission components, thus shortening the production cycle and improving efficiency. However, under continuous high-speed wire drawing conditions, existing continuous wire drawing-annealing equipment is prone to problems when abnormal conditions (such as wire breakage or sudden drop in tension) occur, such as the wire path and subsequent sections easily malfunction. Inertial recoil and whipping effects occur: the wire end may jump and tangle randomly in the guide zone, cooling / shaping inlet, or winding section, which may lead to secondary wire breakage, surface scratches, and increased downtime for troubleshooting. At the same time, if the surface condition of the annealed wire (such as oxide film, lubricant residue, etc.) lacks a stable and consistent "online light shaping / disturbance" process before entering the subsequent stages, the subsequent processes will often be more sensitive to minor surface differences, resulting in fluctuations in the consistency of the finished product. Therefore, this application discloses a continuous integrated enameled aluminum wire drawing and annealing processing device and process. Summary of the Invention

[0004] In view of this, the purpose of this invention is to propose a continuous integrated enameled aluminum wire drawing and annealing processing device and process to solve the problems of existing continuous drawing-annealing equipment being prone to wire breakage or sudden tension drop during high-speed operation, resulting in backlash and tangled wires, scratches, and shutdowns, and inconsistent surface conditions after annealing causing fluctuations in the consistency of finished products.

[0005] To achieve the above objectives, this invention provides a continuous integrated drawing and annealing device for enameled aluminum wire processing, comprising a first mounting and positioning platform and a second mounting and positioning platform. A first set of guide wheels is mounted on the first mounting and positioning platform, and a second set of guide wheels is mounted on one side of the second mounting and positioning platform. An annealing furnace is positioned between the first and second mounting and positioning platforms. A mounting frame is mounted on the side of the second mounting and positioning platform away from the first mounting and positioning platform. A rotating motor is mounted at the bottom of the mounting frame, and a winding drum is mounted at the top of the mounting frame. The output end of the rotating motor is fixedly connected to the winding drum. A cooling and shaping groove is provided between the take-up drum and the second guide wheel assembly; a micro-bending film-breaking mechanism is provided at a corner of the second guide wheel assembly away from the take-up drum. The micro-bending film-breaking mechanism includes a backflush absorption module and a micro-bending film-breaking module. The backflush absorption module is used to release a predetermined buffer length of the wire path instantaneously when the wire breaks or the tension drops suddenly, so as to absorb the backflush energy and reduce the impact of the wire on the subsequent mechanism. The micro-bending film-breaking module is used to form an adjustable micro-bending path of the wire under normal operating conditions, so as to weaken the influence of the oxide film / contamination layer on the surface of the wire and improve the consistency of subsequent processes.

[0006] Preferably, the recoil absorption module includes: a positioning plate, a ratchet, a buffer release arm, a buffer wheel, and a pawl; wherein, the positioning plate is installed on the side of the second guide wheel assembly away from the take-up drum, the ratchet is rotatably mounted on the positioning plate, the buffer release arm is fixedly connected to the ratchet, the buffer wheel is rotatably mounted on the end of the buffer release arm, and the pawl is disposed on the swing arm and engages with the ratchet to lock or unlock the ratchet; the micro-bending film breaking module includes: a swing arm, an inlet guide wheel, an outlet guide wheel, and a return elastic element; wherein, the swing arm is rotatably mounted on one side of the positioning plate, the inlet guide wheel is mounted on the swing arm, the outlet guide wheel is mounted on the other side of the positioning plate, and the return elastic element is connected between the swing arm and the positioning plate to drive the swing arm back, so that the wire forms an adjustable micro-bending path between the inlet guide wheel and the outlet guide wheel.

[0007] Preferably, a torsion spring is provided at the rotating mounting point of the ratchet. One end of the torsion spring is connected to the positioning plate, and the other end is connected to the ratchet. The torsion spring is used to drive the ratchet to rotate to a predetermined angle position when the pawl releases its restraint on the ratchet.

[0008] Preferably, the wire is drawn out after passing through the buffer wheel, the inlet guide wheel and the outlet guide wheel in sequence along the processing direction, and a zigzag path is formed between the inlet guide wheel and the buffer wheel to form a micro-bend.

[0009] Preferably, the pawl is a pawl structure rotatably mounted on the swing arm, and the pawl remains engaged with the ratchet under the action of elastic preload. When the wire tension drops suddenly, causing the swing arm to swing in the return direction under the action of the return elastic element, the pawl disengages from the ratchet, causing the ratchet to rotate under the action of the torsion spring, and driving the buffer release arm to rotate to change the position of the buffer wheel, thereby releasing the buffer length.

[0010] Preferably, the second guide wheel assembly is provided with a fixed straightening wheel and a movable extrusion wheel that cooperates with the fixed straightening wheel. The movable extrusion wheel is position-adjustable by adjusting bolts to straighten the wire and stabilize its tension.

[0011] Preferably, the micro-bending membrane breaking mechanism is disposed between the outlet end of the annealing furnace and the cooling and shaping tank, and the return elastic element provides the return force required for the swing arm to return, so that the micro-bending section formed by the inlet guide wheel and the buffer wheel is maintained in the set working position under normal conditions.

[0012] This invention also discloses a continuous integrated drawing and annealing process for enameled aluminum wire, which, using the aforementioned continuous integrated drawing and annealing process for enameled aluminum wire, includes the following steps:

[0013] S1. The wire is guided by the first guide wheel group and then fed into the annealing furnace;

[0014] S2. After continuous annealing in the annealing furnace, the wire is drawn out by the second guide wheel assembly;

[0015] S3. After the wire is drawn out, it enters the micro-bending film breaking mechanism and passes through the buffer wheel, inlet guide wheel and outlet guide wheel in sequence along the processing direction to form a zigzag path. During normal operation, the pawl engages with the ratchet to keep the buffer release arm in the working position, so that the wire forms a set micro-bend. When a wire breakage or a sudden drop in tension occurs, the pawl releases the ratchet from its limit. The ratchet rotates under the action of the torsion spring at its rotating mounting point and drives the buffer release arm to rotate, so that the buffer wheel is displaced to release the predetermined buffer length ΔL and absorb the backlash. At the same time, the return elastic element drives the swing arm to return to its original position to reduce or eliminate the micro-bend.

[0016] S4. The wire is straightened by the cooperation of the fixed straightening wheel and the moving extrusion wheel, and the position of the moving extrusion wheel is adjusted by the adjusting bolt.

[0017] S5. The wire is cooled and shaped in a cooling and shaping tank;

[0018] S6. After cooling and shaping, the wire is continuously wound up by a rotating motor-driven winding drum.

[0019] Preferably, in step S6, the take-up drum is provided with an inertial trigger locking or braking mechanism; when a wire breakage or a sudden drop in tension occurs in step S3 and causes the swing arm to make a rapid return movement, the inertial trigger locking or braking mechanism is triggered, so as to brake or lock the take-up drum, thereby suppressing the inertial rotation of the take-up drum and reducing the risk of wire loosening and tangling.

[0020] Preferably, in step S6, the rotating motor and the take-up drum are connected by a torque-limiting transmission component, which slips when the transmitted torque exceeds a set threshold to limit the instantaneous tension of the wire; and / or a one-way clutch mechanism is provided in the drive chain of the take-up drum so that the take-up drum is only allowed to drive in the take-up direction, thereby suppressing the reverse swing of the take-up drum when the buffer length ΔL is released in step S3.

[0021] The beneficial effects of this invention are:

[0022] This integrated continuous drawing and annealing enameled aluminum wire processing device and process linearly and continuously arranges the first mounting and positioning platform, annealing furnace, second mounting and positioning platform, and subsequent cooling and shaping tank and winding drum. This allows the wire to continuously complete annealing after being introduced by the first guide wheel group and directly enter the shaping and winding section by the second guide wheel group. This avoids secondary contamination, bumps, and waiting between processes caused by intermediate wire unloading and transfer. Thus, under the same site conditions, it achieves a compact and continuous connection of "drawing—annealing—shaping—winding," improving the overall line cycle time and stability. The micro-bending film-breaking mechanism is located at the wire exit end of the annealing furnace and the cooling and shaping section. Arranged between the slots and at a corner of the second guide wheel group away from the take-up drum, the wire sequentially winds around the buffer wheel, the inlet guide wheel, and the outlet guide wheel along the processing direction to form a zigzag path. The buffer wheel and the inlet guide wheel form a micro-bend section, which allows the wire to generate an adjustable micro-bend during normal operation and creates a slight disturbance to the surface oxide film / contamination layer. With the help of the ratchet locking ratchet, the buffer wheel is stably kept in the working position. This ensures that the amount of micro-bend is controllable, avoids wire drift caused by tension disturbance, and improves the consistency of the wire surface state after annealing. In turn, it reduces the sensitivity of the subsequent shaping and winding processes to surface defects and improves the consistency of the finished product.

[0023] The recoil absorption module integrates "buffered wire release" and "micro-bend release" into a single mechanism operating in two states: When a wire breakage or sudden drop in tension occurs, the swing arm returns to its original position under the action of the return elastic element, causing the pawl to disengage from the ratchet. The ratchet, under the rotational torque of the torsion spring at its rotation mounting point, rotates to a predetermined angle and drives the buffer release arm to rotate, causing the buffer wheel to displace and instantly release a predetermined buffer length ΔL. This absorbs the instantaneous inertial recoil of the broken wire in a "path-based wire release" manner, reducing the impact of the wire on the second guide wheel group, the cooling and shaping groove inlet, and the winding section. At the same time, the micro-bend section is reduced or eliminated, further reducing the probability of wire tip jumping, scratching, tangling, and secondary wire breakage. Furthermore, the torsion spring rotates the ratchet to a predetermined angle, making the buffer stroke repeatable and the release amount controllable, which is beneficial for rapid recovery of threading and restart under abnormal working conditions, improving maintenance efficiency and equipment reliability.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0035] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains.

[0036] like Figures 1 to 6As shown, the continuous integrated drawing and annealing enameled aluminum wire processing device includes a first mounting and positioning platform 1 and a second mounting and positioning platform 3. A first guide wheel assembly 2 is mounted on the first mounting and positioning platform 1, and a second guide wheel assembly 4 is mounted on one side of the second mounting and positioning platform 3. An annealing furnace 8 is positioned between the first mounting and positioning platform 1 and the second mounting and positioning platform 3. A mounting frame 5 is mounted on the side of the second mounting and positioning platform 3 away from the first mounting and positioning platform 1. A rotary motor 6 is mounted at the bottom of the mounting frame 5, and a winding drum 7 is mounted at the top of the mounting frame 5. The output end of the rotary motor 6 is fixedly connected to the winding drum 7. A cooling and shaping groove 9 is provided between 7 and the second guide wheel group 4; a micro-bending film breaking mechanism is provided at a corner of the second guide wheel group 4 away from the winding drum 7. The micro-bending film breaking mechanism includes a backflush absorption module and a micro-bending film breaking module. The backflush absorption module is used to release a predetermined buffer length of the wire path instantaneously when the wire breaks or the tension drops suddenly, so as to absorb the backflush energy and reduce the impact of the wire on the subsequent mechanism. The micro-bending film breaking module is used to form an adjustable micro-bending path of the wire under normal operating conditions, so as to weaken the influence of the oxide film / contamination layer on the surface of the wire and improve the consistency of subsequent processes.

[0037] The wire enters from the first mounting and positioning platform 1, is guided by the first guide wheel group 2, and is continuously fed into the annealing furnace 8 located between the first mounting and positioning platform 1 and the second mounting and positioning platform 3 for online annealing. After annealing, the wire exits from the outlet end of the annealing furnace 8 and enters the second guide wheel group 4 on one side of the second mounting and positioning platform 3 for guidance and reversal, allowing the wire to directly enter the subsequent section without intermediate winding and unwinding, thereby achieving continuous connection between drawing and annealing and reducing reel changes and secondary contamination. After being led out from the second guide wheel group 4, the wire first enters the arrangement of... The micro-bending film-breaking mechanism located at a corner of the second guide wheel assembly 4 away from the take-up drum 7, during normal continuous production, causes the wire to form an adjustable micro-bend along a set zigzag path. This slightly breaks / disturbs the oxide film and drawing lubricant residue on the wire surface, improving surface consistency and reducing the probability of surface defects and increasing stability during subsequent shaping and winding processes. Simultaneously, this micro-bending path can be adjusted to adapt to different wire diameters and speeds, avoiding surface damage caused by excessive bending. When wire breakage or other issues occur during production... In abnormal operating conditions such as sudden tension drop, the recoil absorption module is triggered, causing the wire path to release a predetermined buffer length instantaneously. This buffer length is used to absorb and unload the inertial recoil at the moment of wire breakage, reducing the impact of the wire on the second guide wheel group 4, the inlet of the cooling and shaping tank 9, and the take-up section. This avoids secondary scratches, tangling, or contamination caused by wire jumping around, and reduces secondary wire breakage and equipment downtime for maintenance due to impact. After the wire completes the micro-bending and recoil absorption treatment, it enters the cooling and shaping tank 9 for cooling and shaping, ensuring that the temperature and composition after annealing are optimal. The woven state is stabilized, and the thermal softening deformation and springback during subsequent winding are reduced, thereby improving the winding quality and coil shape consistency. Finally, the wire is led to the winding drum 7 at the top of the mounting frame 5, and the winding drum 7 is driven to rotate continuously by the rotating motor 6 at the bottom of the mounting frame 5 to complete the winding. With the help of the aforementioned micro-bending film breaking to improve the surface condition and the backflow absorption to suppress abnormal impact, the risk of surface scratches, tangled wires and downtime caused by tension fluctuations and wire breakage backflow can be significantly reduced while maintaining continuous and efficient production, thereby improving the overall machine operation stability, finished product consistency and maintenance cycle.

[0038] like Figures 1 to 6As shown, the backwash absorption module includes: a positioning plate 13, a ratchet 17, a buffer release arm 18, a buffer wheel 19, and a pawl 20; wherein, the positioning plate 13 is installed on the side of the second guide wheel group 4 away from the take-up drum 7, the ratchet 17 is rotatably mounted on the positioning plate 13, the buffer release arm 18 is fixedly connected to the ratchet 17, the buffer wheel 19 is rotatably mounted on the end of the buffer release arm 18, and the pawl 20 is set on the swing arm 14 and engages with the ratchet 17 to lock or unlock the ratchet 17; the micro-bending membrane breaking module includes: a swing arm 14, an inlet guide wheel 15, an outlet guide wheel 16, and... Return elastic element 21; wherein, the swing arm 14 is rotatably mounted on one side of the positioning plate 13, the inlet guide wheel 15 is mounted on the swing arm 14, the outlet guide wheel 16 is mounted on the other side of the positioning plate 13, and the return elastic element 21 is connected between the swing arm 14 and the positioning plate 13 to drive the swing arm 14 back to its original position, so that the wire forms an adjustable micro-bend path between the inlet guide wheel 15 and the outlet guide wheel 16, wherein the wire passes through the buffer wheel 19, the inlet guide wheel 15 and the outlet guide wheel 16 in sequence along the processing direction before being led out, and a zigzag path is formed between the inlet guide wheel 15 and the buffer wheel 19 to form a micro-bend section;

[0039] Specifically, the positioning plate 13 is installed on the side of the second guide wheel assembly 4 away from the take-up drum 7 as the installation reference for each component. The swing arm 14 is rotatably mounted on one side of the positioning plate 13 at its rotational connection point and has a tendency to return to its predetermined position under the action of the return elastic member 21. The inlet guide wheel 15 is mounted on the swing arm 14, and the outlet guide wheel 16 is fixedly mounted on the other side of the positioning plate 13. The ratchet 17 is rotatably mounted on the positioning plate 13, and the buffer release arm 18 is fixedly connected to the ratchet 17. The buffer wheel 19 is rotatably mounted on the buffer release arm 18. At the end, the pawl 20 is rotatably mounted on the swing arm 14 and tends to engage with the ratchet 17 under elastic preload to lock or unlock the ratchet 17. The wire is led out after passing through the buffer wheel 19, the inlet guide wheel 15 and the outlet guide wheel 16 in sequence along the processing direction. Since the buffer wheel 19 and the inlet guide wheel 15 form a zigzag path with a micro-bend, the wire will produce adjustable micro-bend deformation during normal continuous operation and cause slight disturbance to the oxide film and contamination layer on the wire surface, thereby improving the surface uniformity and reducing the cost of subsequent processes. This improves defect sensitivity and product consistency. Simultaneously, the inlet guide wheel 15, swinging with the swing arm 14, allows for micro-bending adjustment to accommodate different wire diameters and speeds, preventing excessive bending that could cause surface scratches. Furthermore, the recoil absorption module, consisting of ratchet 17, buffer release arm 18, and buffer wheel 19, maintains the working position of the buffer wheel 19 stably when the pawl 20 is locked. This prevents significant fluctuations in the micro-bending section under normal conditions due to tension disturbances, thereby improving cable routing stability and straightening quality. Conversely, in the event of a wire breakage or... When abnormal working conditions such as sudden drop in tension require unloading the impact, the pawl 20 can transition from the engaged state to the unlocked state, allowing the ratchet 17 to rotate and drive the buffer release arm 18 to change the position of the buffer wheel 19. This allows the wire path to release a predetermined buffer length instantly to absorb recoil energy and reduce the impact of the wire on the subsequent mechanism. This reduces the risk of secondary scratches, wire tangling, and downtime maintenance caused by wire jumping, and achieves compatibility between "micro-bending to improve surface and stable wire routing" in normal conditions and "rapid wire release buffer and protection of subsequent sections" in abnormal conditions.

[0040] A torsion spring is provided at the rotating mounting point of the ratchet 17. One end of the torsion spring is connected to the positioning plate 13, and the other end is connected to the ratchet 17. It is used to drive the ratchet 17 to rotate to a predetermined angle position when the pawl 20 releases its limit on the ratchet 17. The pawl 20 is a pawl structure that is rotatably mounted on the swing arm 14. The pawl 20 is kept engaged with the ratchet 17 under the action of elastic preload. When the wire tension drops suddenly and the swing arm 14 swings in the return direction under the action of the return elastic element 21, the pawl 20 disengages from the ratchet 17, causing the ratchet 17 to rotate under the action of the torsion spring, and driving the buffer release arm 18 to rotate to change the position of the buffer wheel 19, thereby releasing the buffer length.

[0041] Specifically, a torsion spring is provided at the rotating mounting point of the ratchet 17. One end of the torsion spring is connected to the positioning plate 13, and the other end is connected to the ratchet 17. This allows the ratchet 17 to automatically rotate to a predetermined angle position under the rotational torque of the torsion spring after it loses the restraint of the pawl 20. This prevents the ratchet 17 from being at a random angle, which could lead to unstable engagement or uncontrollable buffer stroke in the next engagement. The pawl 20 is a pawl structure rotatably mounted on the swing arm 14. Under the action of elastic preload, the pawl 20 remains engaged with the ratchet 17 to lock the ratchet 17 under normal tension. This keeps the buffer release arm 18 and the buffer wheel 19 in the set working position and stabilizes the wire routing path, thereby obtaining more stable tension and a more consistent micro-bending film breaking effect during continuous processing. When the wire breaks or the tension drops suddenly, the traction force of the wire on the mechanism decreases, causing the swing arm 14 to return to the elastic element 2. Under the action of 1, the swing arm 14 swings in the return direction, causing the pawl 20 to lift or disengage from the ratchet 17, thus disengaging from the ratchet 17. The ratchet 17 then rotates under the action of the torsion spring and drives the buffer release arm 18 fixedly connected to it to rotate, causing the position of the buffer wheel 19 to change and the wire path to release the buffer length ΔL instantaneously. This unloads the inertial backlash at the moment of wire breakage in the form of "path release" and significantly reduces the impact of the wire on the guide wheel, the double straightening wheel group and the inlet of the subsequent cooling and shaping tank 9. This reduces problems such as surface scratches, swing contamination, secondary wire breakage and wire tangling caused by wire pulling. At the same time, the torsion spring rotates the ratchet 17 to a predetermined angle to ensure that the buffer action has repeatable stroke and controllable release amount, making the protection action under abnormal working conditions stable and reliable and facilitating the rapid recovery of production.

[0042] In this embodiment, the buffer length ΔL is determined by the increase in the wire path corresponding to the displacement of the buffer wheel 19 in the released state relative to the working state. Specifically, the buffer wheel 19 is installed at the end of the buffer release arm 18. The buffer release arm 18 rotates with the ratchet 17, generating an angular displacement, thereby causing the buffer wheel 19 to form a defined displacement trajectory in space. This causes the wire to instantaneously increase and release the buffer length ΔL along the zigzag path between the buffer wheel 19, the inlet guide wheel 15, and the outlet guide wheel 16. To ensure that ΔL is repeatable and controllable, the rotation termination position of the ratchet 17 can be limited by a mechanical limiting structure (e.g., setting a limiting block or limiting groove on the positioning plate 13, and...). The ratchet 17 or the buffer release arm 18 cooperate to form a rotary stop, so that the ratchet 17 rotates to the same termination angle each time under the action of the torsion spring, thereby fixing the termination position of the buffer wheel 19 and ensuring that ΔL is stable and consistent; at the same time, the limit position / stop position is adjustable (for example, by a replaceable stop, an adjustable stop screw or a multi-hole installation method), so that ΔL can be set according to the differences in wire diameter, wire speed and winding inertia, so that under abnormal working conditions, the backflush can be fully unloaded and the excessive unwinding can be avoided to prevent subsequent loosening of the wire.

[0043] Furthermore, to avoid accidental disengagement of the pawl 20 due to normal tension fluctuations, in this embodiment, the pawl 20 always tends to engage with the ratchet 17 under the action of elastic preload, and the engagement angle / engagement depth of the pawl 20 and the ratchet 17 is set to not self-unlock within the normal cable tension range; only when the cable breaks or the tension drops sharply, causing a significant reduction in the traction force of the cable on the inlet guide wheel 15, the swing arm 14 generates a rapid return swing under the action of the return elastic element 21. The relative movement of the swing arm 14 causes the pawl 20 to cross the disengagement threshold and generate a defined lifting / retracting stroke, thereby achieving reliable separation of the pawl 20 and the ratchet 17. Furthermore, the swing arm can... A return stop / travel limit is set on the return path of 14 to fix the return endpoint of the swing arm 14, thereby ensuring the consistency of the pawl 20's disengagement action each time. The high-frequency vibration of the swing arm 14 under normal working conditions can be suppressed by adjusting the preload of the return elastic element 21 or by setting damping elements (such as friction damping pads, damping sleeves, or buffers), reducing the risk of shaking and disengagement caused by minor tension disturbances. In this way, under "normal working conditions", the pawl 20 is stably locked to ensure that the working position of the micro-bend section does not drift. Under "abnormal working conditions", the pawl 20 can quickly and reliably release the lock when the tension drops sharply, ensuring that the ΔL release action is fast and reliable.

[0044] like Figures 3 to 5 As shown, the second guide wheel group 4 is provided with a fixed straightening wheel 10 and a movable extrusion wheel 12 that cooperates with the fixed straightening wheel 10. The movable extrusion wheel 12 is position-adjustable by adjusting bolt 11 to straighten the wire and stabilize the tension. The micro-bending film breaking mechanism is set between the wire outlet end of the annealing furnace 8 and the cooling and shaping tank 9. The return elastic element 21 provides the return force required for the swing arm 14 to return, so that the micro-bending section formed by the inlet guide wheel 15 and the buffer wheel 19 is kept in the set working position under normal conditions.

[0045] Specifically, a fixed straightening roller 10 is installed at the second guide roller group 4. The movable extrusion roller 12 cooperates with the fixed straightening roller 10 to form a straightening channel. The movable extrusion roller 12 is position-adjustable by adjusting bolts 11, so that the extrusion amount and straightening pressure can be set according to the wire diameter, hardness and process speed. This ensures that the wire is effectively straightened before entering the cooling and shaping tank 9 and the winding section, and suppresses deviation, friction and surface scratches caused by residual bending. At the same time, the straightening roller group plays a certain role in stabilizing and buffering the wire tension, reducing the impact of tension fluctuations on the subsequent shaping and winding coil shape. The micro-bending film breaking mechanism is arranged between the wire exit end of the annealing furnace 8 and the cooling and shaping tank 9, so that the wire is in a section with controllable surface condition and tight process connection after annealing and before entering the cooling and shaping section. The micro-bending film breaking mechanism is formed by the inlet guide roller 15 and the buffer roller 19. Under normal conditions, the bend slightly disturbs the surface oxide film / contamination layer and improves its consistency. The return elastic element 21 provides a return force to the swing arm 14, ensuring that the swing arm 14 remains stably in the set working position during normal operation. This ensures that the micro-bending amount and the wire path remain consistent during production and is conducive to the stable setting of straightening parameters, avoiding straightening pressure fluctuations, wire deviation, or local wear caused by micro-bending drift. When the abnormal tension drops sharply, the return elastic element 21 can drive the swing arm 14 to move in the return direction to cooperate with the recoil absorption module to release the buffer length and reduce or remove the micro-bending. This protects the inlet of the subsequent cooling and shaping tank 9 and the winding section while reducing the risk of wire tip whipping and tangling. It achieves the combined effect of "stable straightening + improved surface by micro-bending + consistent shaping and winding" during normal operation and "rapid unloading of impact + reduced damage" under abnormal conditions.

[0046] like Figure 7 As shown, this invention also discloses a continuous integrated drawing and annealing enameled aluminum wire processing technology, applied to the aforementioned continuous integrated drawing and annealing enameled aluminum wire processing apparatus, comprising the following steps:

[0047] S1. The wire is guided by the first guide wheel group 2 and then fed into the annealing furnace 8. In this step, the first guide wheel group 2 is used to reverse, limit, and guide the incoming wire from the upstream, so that the wire enters the annealing furnace 8 at a stable entry angle, thereby reducing friction scratches and tension fluctuations caused by uneven wear and jumping at the entry end of the wire, and ensuring continuous and stable operation of the annealing section. In specific implementation, the wheel spacing and wrap angle of the first guide wheel group 2 can be set according to the wire diameter to balance the guiding stability and the controllability of friction damage.

[0048] S2. After continuous annealing in annealing furnace 8, the wire is led out by the second guide wheel group 4. In this step, after the wire is continuously annealed in annealing furnace 8, the second guide wheel group 4 guides and reverses the wire exit end, so that the annealed wire can enter the subsequent section without intermediate winding, thereby reducing the risk of oxidation, contamination and collision caused by intermediate transfer, and improving the continuous processing efficiency of the whole line. At the same time, the second guide wheel group 4 can stably constrain the wire exiting the furnace, providing a basis for the stable operation of the subsequent micro-bending film breaking mechanism.

[0049] S3. After the wire is drawn out, it enters the micro-bending film breaking mechanism and passes through the buffer wheel 19, the inlet guide wheel 15, and the outlet guide wheel 16 in sequence along the processing direction to form a zigzag path. During normal operation, the pawl 20 engages with the ratchet 17 to keep the buffer release arm 18 in the working position, so that the wire forms a set micro-bend. When a wire breakage or a sudden drop in tension occurs, the pawl 20 releases the limit on the ratchet 17. The ratchet 17 rotates under the action of the torsion spring at its rotating mounting point and drives the buffer release arm 18 to rotate, so that the buffer wheel 19 is displaced to release the predetermined buffer length ΔL and absorb the backlash. At the same time, the return elastic element 21 drives the swing arm 14 to return to its original position to reduce or eliminate the micro-bend. Under normal operation, the zigzag path formed by the buffer wheel 19 and the inlet guide wheel 15 constitutes a micro-bend section. This micro-bend section slightly disturbs the oxide film and contamination layer on the surface of the wire and improves the surface condition consistency, thereby reducing the sensitivity of subsequent sections to surface micro-defects and improving the consistency of the finished product. Because the pawl 20 engages and locks with the ratchet 17, the buffer release arm 18 and the buffer wheel 19 are stably held in the working position, making the micro-bending amount stable and controllable, avoiding micro-bending amount drift caused by tension disturbances; when a wire breakage or sudden drop in tension occurs, the traction force of the wire on the mechanism is significantly reduced. After the pawl 20 releases its limit on the ratchet 17, the ratchet 17 rotates to a predetermined angle position under the action of the torsion spring and drives the buffer release arm 18 to rotate, causing the buffer wheel 19 to shift and the wire path to release the buffer length ΔL instantaneously. This absorbs the recoil energy in the form of "path release", reduces the impact of the wire hitting the subsequent mechanism, and reduces the risk of wire snagging, tangling and secondary wire breakage caused by the wire jumping around; at the same time, the return elastic element 21 drives the swing arm 14 to return to its original position to reduce or eliminate the micro-bending, so that the wire is no longer forced to pass through a large folded path at the moment of wire breakage, thereby further reducing the probability of hitting, scratching and jamming, and making the mechanism easier to resume threading and continue production.

[0050] S4. The wire is straightened by the cooperation of the fixed straightening roller 10 and the movable extrusion roller 12, and the position of the movable extrusion roller 12 is adjusted by the adjusting bolt 11. In this step, the fixed straightening roller 10 and the movable extrusion roller 12 form a straightening channel. The position of the movable extrusion roller 12 is changed by adjusting the bolt 11 to adjust the extrusion amount, thereby correcting the curvature of the wire and stabilizing the output posture of the wire, reducing the risk of wire deviation and abrasion before entering the cooling and shaping tank 9 and the winding drum 7. At the same time, the straightening process can play a certain shaping role in the wire tension, making the subsequent cooling and shaping and winding drum shape more consistent, reducing problems such as loose finished drum shape and interlayer misalignment.

[0051] S5. The wire is cooled and shaped in the cooling and shaping tank 9. In this step, the annealed wire enters the cooling and shaping tank 9 for cooling and shaping, which rapidly reduces the temperature of the wire and stabilizes its shape and structure, thereby reducing plastic deformation and springback caused by traction and winding in the hot soft state and improving the stability of the winding coil. The cooling and shaping tank 9 can also inhibit the re-oxidation and adhesion of the wire surface to a certain extent, ensuring the surface quality of the finished winding product.

[0052] S6. After cooling and shaping, the wire is continuously wound by the take-up drum 7 driven by the rotating motor 6. In this step, the rotating motor 6 drives the take-up drum 7 to continuously wind the finished wire, which, combined with the buffer unwinding in S3 and the straightening and stabilization in S4, can reduce tension fluctuations and wire deviation during the winding process, making the coil shape tighter and neater and reducing surface scratches. In addition, in continuous production, the winding section is the position where inertia and tension coupling are most obvious. Subsequent inertia-triggered braking and torque limiting / one-way clutch measures can further reduce the risk of wire breakage or sudden tension drop, and improve the safety and recovery efficiency of the entire line.

[0053] In step S6, the take-up drum 7 is equipped with an inertial trigger locking or braking mechanism; when a wire breakage or a sudden drop in tension occurs in step S3 and causes the swing arm 14 to make a rapid return movement, the inertial trigger locking or braking mechanism is triggered, so that the take-up drum 7 is braked or locked to suppress the inertial rotation of the take-up drum 7 and reduce the risk of wire loosening and tangling.

[0054] The inertial triggering locking or braking mechanism can be set on the winding drum 7 or its drive shaft in the form of centrifugal block-pawl, pendulum-friction plate or roller wedging, etc. The triggering signal can be transmitted by the rapid return movement of the swing arm 14 through the mechanical linkage / cable, or the instantaneous speed change caused by the return of the swing arm 14 can be used to trigger inertial triggering, thereby achieving rapid braking without the need for electronic control response. This measure can suppress the "empty winding" and loose coil accumulation caused by the continued rotation of the winding drum 7 due to inertia at the moment of wire breakage, avoid wire back-throwing and entanglement, jamming of guide wheel or winding into mechanism, and improve safety and reset efficiency under abnormal working conditions.

[0055] In step S6, the rotating motor 6 and the take-up drum 7 are connected by a torque-limiting transmission component. The torque-limiting transmission component slips when the transmitted torque exceeds a set threshold to limit the instantaneous tension of the wire; and / or a one-way clutch mechanism is provided in the transmission chain of the take-up drum 7 so that the take-up drum 7 is only allowed to drive in the winding direction, thereby suppressing the reverse swing of the take-up drum 7 when the buffer length ΔL is released in step S3.

[0056] Torque-limiting transmission components can employ friction plate torque-limiting couplings, magnetic powder torque limiters, or spring-pressed slippage structures. This allows the winding end to automatically "yield" and slip when tension abnormally increases, there is a momentary impact, or the mechanism jams. This limits the instantaneous tension of the wire and reduces the probability of wire breakage, while also reducing the impact on the guide rollers, the re-straightening roller group, and the micro-bending film-breaking mechanism. The one-way clutch mechanism can be set in the winding drum 7 or its transmission chain in the form of roller one-way clutch or ratchet one-way clutch. This ensures that the winding drum 7 is not affected when it is driving in the normal winding direction. However, when the buffer length ΔL is released at S3 or the wire rebounds due to wire breakage, it can suppress the backlash and loosening caused by the reverse rotation of the winding drum 7. This further reduces tangling, wire tangling, scratches, and downtime for troubleshooting, achieving self-protection and rapid recovery of the winding section under abnormal working conditions.
