Description

Technical Field

[0001] This application belongs to the technical field of pipeline production equipment, specifically relating to a support mechanism and coiling equipment. Background Technology

[0002] A coil is a heat exchange component, typically installed inside the water tank of solar water heaters and heat pump water heaters. Refrigerant flows inside the coil, and heat exchange occurs between the coil and the cold water in the tank. The heat from the refrigerant is transferred to the cold water, thus raising the water temperature in the tank. The coil has a spiral structure and requires coil manufacturing equipment for production and processing.

[0003] In related technologies, coiling equipment includes a frame, a forming mold, and a feeding mechanism. Both the feeding mechanism and the forming mold are connected to the frame. During operation, the long strip of pipe is fixed to the feeding mechanism, which drives the pipe to move. During the movement of the pipe, the forming mold can bend and shape the pipe so that the long strip of pipe can form a spiral coil.

[0004] However, when it is necessary to produce coils with different pitches, the coils need to be transferred to other equipment after forming for pitch adjustment, which reduces the production efficiency of the coils. Summary of the Invention

[0005] This application provides a support mechanism and coiling equipment to solve the technical problem in related technologies that when coils with different pitches need to be produced, they need to be transferred to other equipment for pitch adjustment after coil forming, which reduces the production efficiency of coils.

[0006] Firstly, this application provides a support mechanism, including:

[0007] A frame, which is used to be installed at the discharge end of the coil equipment;

[0008] A support assembly is slidably connected to the frame along the height direction of the frame, and the support assembly is used to support the coils output by the coil equipment;

[0009] A lifting assembly is connected to the frame and is used to drive the support assembly to rise and fall.

[0010] In some embodiments, the support assembly includes a base and a chuck, the base being slidably connected to the frame, the chuck being connected to the base, and a support space being formed between the chuck and the base for accommodating the coil.

[0011] In some embodiments, the base includes a base plate and rollers, the base plate is slidably connected to the frame, the rollers are rotatably connected to the base plate, the chuck includes a connecting part and a rotating part, the connecting part is connected to the base plate, the rotating part is rotatably connected to the connecting part, the rotation axis of the rollers is perpendicular to the rotation axis of the rotating part and connected to the rollers, and the support space is formed between the chuck rollers and the rotating part of the rollers.

[0012] In some embodiments, a reset assembly is further included, wherein the connecting portion is rotatably connected to the base plate, the rotation axis of the connecting portion is parallel to the rotation axis of the roller, the reset assembly is connected between the connecting portion and the base plate, and the reset assembly is used to drive the connecting portion to reset after rotation.

[0013] In some embodiments, the reset assembly includes a plurality of springs, one end of which is connected to the connecting portion and the other end of which is connected to the base plate, and the plurality of springs are symmetrically distributed on opposite sides of the connecting portion.

[0014] In some embodiments, the lifting assembly includes a screw, a nut, and a drive member. One end of the screw is connected to the support assembly, and the other end of the screw passes through the frame. The nut is threadedly connected to the screw, and the drive member is connected to the frame. The drive member is used to drive the nut to rotate so that the screw drives the support assembly to lift.

[0015] In some embodiments, an adjustment component is further included, the frame being connected to the adjustment component, the adjustment component being used to drive the frame to move in order to adjust the distance between the frame and the coil equipment.

[0016] In some embodiments, the adjustment assembly includes a plate and an adjustment member, the frame is slidably connected to the plate, the adjustment member is connected to the plate, and the adjustment member is used to drive the frame to move on the plate to adjust the distance between the frame and the coiling device.

[0017] In some embodiments, a protective plate is also included. The adjusting member includes a main body and a driving end. The main body is connected to the plate body. A connecting member is provided between the driving end and the frame. The protective plate is connected to the plate body. The protective plate is used to cover part of the driving end and part of the connecting member.

[0018] Secondly, this application provides a coiling device, including a frame, a forming mold, a feeding mechanism, and a support mechanism. The feeding mechanism and the forming mold are both connected to the frame. The feeding mechanism is used to drive the pipe to move, and the forming mold is used to bend and form the pipe. The frame of the support mechanism is disposed at the discharge end of the forming mold.

[0019] This application provides a support mechanism and a coiling device. The support mechanism, during the continuous feeding and forming process of the coiling device, has the end of the coil closest to the device fixed by the device. By adjusting the support assembly to a height higher than the feeding end of the coiling device, the tube, while continuously feeding and spirally forming, extends upwards with the feeding end of the coiling device as the fixed end and the support position of the support assembly as the support point. This naturally widens the gap between adjacent spiral segments, directly forming a spiral coil with a specified pitch. The lifting assembly drives the support assembly to slide and rise along the height of the frame, flexibly adjusting the height difference between the support assembly and the feeding end of the coiling device. A larger height difference results in a larger coil pitch, and a smaller height difference results in a smaller coil pitch, thus directly producing coils with different pitches. Furthermore, the height of the support assembly can be adjusted in real time while a single coil is continuously feeding and forming, creating a segmented variable pitch structure for the same coil. This eliminates the need for secondary pitch adjustment after coiling by transferring it to other equipment, simplifying the production process and improving coil production efficiency.

[0038] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] In related technologies, coiling equipment includes a frame, a forming mold, and a feeding mechanism. Both the feeding mechanism and the forming mold are connected to the frame. During operation, the long strip of pipe is fixed to the feeding mechanism, which drives the pipe to move. During the movement of the pipe, the forming mold can bend and shape the pipe so that the long strip of pipe can form a spiral coil.

[0041] However, existing coiling equipment can only form spiral coils with a single pitch during continuous forming. It lacks effective support and pitch adjustment structure for the formed coils, and cannot adjust the pitch in real time during coiling. When it is necessary to produce coils with different pitch specifications, the formed coils must be removed from the coiling equipment and transferred to other equipment such as special twisting machines and pitch adjustment devices for secondary stretching, twisting or rewinding to adjust the pitch, which reduces the production efficiency of coils.

[0042] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0043] like Figure 1 As shown, this application embodiment provides a support mechanism, including a frame 100, a support component 200, and a lifting component 300. The frame 100 is used to be installed at the discharge end of the coiling equipment. Along the height direction of the frame 100, the support component 200 is slidably connected to the frame 100 and is used to support the coils output by the coiling equipment. The lifting component 300 is connected to the frame 100 and is used to drive the support component 200 to rise and fall.

[0044] By adopting the above technical solution, during the continuous feeding and forming process of the coiling equipment, the end of the coil closest to the coiling equipment is limited and fixed by the coiling equipment. By adjusting the support component 200 to a height higher than the feeding end of the coiling equipment, the tube, while continuously feeding and spirally forming, forms an upwardly inclined extension posture with the feeding end of the coiling equipment as the fixed end and the support position of the support component 200 as the support point. This naturally widens the gap between adjacent spiral segments, directly forming a spiral coil with a specified pitch. The lifting component 300 drives the support... The component 200 slides and rises along the height of the frame 100, flexibly adjusting the height difference between the support component 200 and the discharge end of the coiling equipment. When the height difference increases, the coil pitch increases accordingly; when the height difference decreases, the coil pitch decreases accordingly. This allows for the direct processing of coils with different pitches. Furthermore, the height of the support component 200 can be adjusted in real time while a single coil is continuously being discharged and formed, enabling the same coil to form a segmented variable pitch structure. This eliminates the need to transfer the coil to other equipment for secondary pitch adjustment after forming, simplifying the production process and improving the production efficiency of the coil.

[0045] Combination Figure 2 , Figure 3 and Figure 4In this embodiment, the frame 100 includes a first connecting plate 110, a first support rod 120, a second support rod 130, and a second connecting plate 140. There are two first connecting plates 110, which are spaced apart. Each first connecting plate 110 has two first support rods 120. Two second support rods 130 are arranged between the opposing first support rods 120 of the two first connecting plates 110. The second connecting plate 140 is connected to the ends of the multiple first support rods 120 that are away from the first connecting plate 110.

[0046] By adopting the above technical solution, the frame 100 uses two spaced first connecting plates 110 as the basic load-bearing structure. Two first support rods 120 are set on each first connecting plate 110 to form a vertical support structure. Two second support rods 130 are horizontally connected between the opposite first support rods 120. At the same time, second connecting plates 140 are set at the upper ends of multiple first support rods 120, forming a closed frame structure. This improves the overall structural rigidity and load-bearing stability of the frame 100, prevents swaying, deformation or tilting when the support components 200 are raised and lowered and when the pallet tube is supported, and enhances the structural strength and reliability of the frame 100 in continuous working conditions.

[0047] The support assembly 200 includes a base 210 and a chuck 220. The base 210 is slidably connected to the frame 100, and the chuck 220 is connected to the base 210. A support space 230 is formed between the chuck 220 and the base 210, and the support space 230 is used to accommodate the coil.

[0048] In this embodiment, the base 210 is slidably connected to the second connecting plate 140 of the frame 100.

[0049] By adopting the above technical solution, during the continuous discharge of the coil, the coil is accommodated in the support space 230 formed by the chuck 220 and the base 210. The top of the coil abuts against the upper chuck 220, and the bottom of the coil abuts against the base 210. This allows the coil to be constrained by both upper and lower limits during the moving and forming process. This not only stably supports the coil to prevent it from sagging, shifting, or shaking, but also guides the spiral shape in a regular manner, ensuring that the coil pitch is uniform and the shape is regular. At the same time, the support space 230 can form a smooth sliding channel for the coil, allowing it to pass smoothly during the continuous discharge process. This effectively reduces frictional damage between the coil and the support components, and improves the dimensional accuracy and appearance quality of the formed coil.

[0050] The base 210 includes a base plate 211 and a roller 212. The base plate 211 is slidably connected to the frame 100, and the roller 212 is rotatably connected to the base plate 211. The chuck 220 includes a connecting part 221 and a rotating part 222. The connecting part 221 is connected to the base plate 211, and the rotating part 222 is rotatably connected to the connecting part 221. The rotation axis of the roller 212 is perpendicular to the rotation axis of the rotating part 222 and is connected to the roller 212. The support space 230 is formed between the roller 212 and the rotating part 222.

[0051] By adopting the above technical solution, when the coil moves within the support space 230, the upper part of the coil contacts the rotating part 222 and drives the rotating part 222 to rotate synchronously through friction. The lower part of the coil contacts the roller 212 and drives the roller 212 to rotate synchronously. This transforms traditional sliding friction into rolling friction, reducing the frictional resistance between the coil and the rotating part 222 and the roller 212, preventing the outer wall of the coil from being scratched or abraded. At the same time, it makes the coil discharge smoother and more stable, preventing the coil from deforming or the pitch from getting out of control due to excessive resistance. The rotation axis of the roller 212 is perpendicular to the rotation axis of the rotating part 222, which can adapt to the movement trends of the coil in different directions when it spirals forward. It provides rolling support and guidance synchronously from two vertical directions, further ensuring that the coil is stable in posture, does not deviate, and does not jam during the moving and forming process. This makes the spiral forming and pitch adjustment process more continuous and reliable, improving the coil forming accuracy and production stability.

[0052] In this embodiment, two guide rods 213 are provided on the side of the base plate 211 facing the second connecting plate 140. One end of the guide rod 213 is fixedly connected to the base plate 211, and the other end of the guide rod 213 passes through and is slidably connected to the second connecting plate 140. The base plate 211 is slidably connected to the second connecting plate 140 of the frame 100 through the guide rods 213.

[0053] By adopting the above technical solution and using the guide rod 213, the lifting and lowering movement of the base plate 211 can be linearly guided, limiting the shaking, swaying or radial displacement of the base plate 211 during the lifting and lowering process, maintaining the stable linear movement of the support component 200 along the height direction of the frame 100, preventing uneven force on the coil, pitch deviation or forming deformation caused by the skew position of the support component 200, thereby improving the processing accuracy and operational stability of the coil pitch.

[0054] In other embodiments, the base plate 211 and the second connecting plate 140 can also be slidably connected by a guide rail and slider or a groove and rail. The above structures can provide stable and reliable linear guidance for the base plate 211, reduce frictional resistance and movement gap during the lifting process, and make the lifting action of the support component 200 smoother and more stable.

[0055] In this embodiment, a fixing plate 214 is provided on both sides of the base plate 211, and a fixing shaft 215 is provided between the two fixing plates 214. A roller 212 is sleeved on and rotatably connected to the fixing shaft 215. A connecting part 221 is connected to the fixing shaft 215, and a rotating part 222 is rotatably connected to the upper side of the connecting part 221 to form a support space 230 between the rotating part 222 and the roller 212. The roller 212 has a circular cross-section, and the rotating part 222 has a circular cross-section. In other embodiments, the connecting part 221 can also be directly connected to the base plate 211. By making the height of the rotating part 222 higher than the height of the roller 212, a support space 230 can also be formed between the rotating part 222 and the roller 212.

[0056] The support mechanism also includes a reset assembly 400. The connecting part 221 is rotatably connected to the base plate 211. The rotation axis of the connecting part 221 is parallel to the rotation axis of the roller 212. The reset assembly 400 is connected between the connecting part 221 and the base plate 211. The reset assembly 400 is used to drive the connecting part 221 to reset after rotation.

[0057] In this embodiment, the connecting part 221 is sleeved and rotatably connected to the fixed shaft 215, and the connecting part 221 is rotatably connected to the base plate 211 through the fixed shaft 215.

[0058] By adopting the above technical solution, when the coil moves within the support space 230, the coil and the rotating part 222 abut against each other, pushing the connecting part 221 to rotate adaptively relative to the base plate 211. This automatically adjusts the support posture according to the changes in the coil's spiral angle, outer diameter, and pitch, preventing rigid support from causing the coil to be squeezed and deformed or stuck. This ensures that the support component 200 and the coil always maintain a good fit. After rotation adjustment, the reset component 400 can promptly drive the connecting part 221 to spring back and reset, ensuring continuous flexible support and dynamic following of the coil while preventing excessive swaying of the support components. This makes the coil's posture stable and its forming regular during continuous discharge and pitch adjustment, effectively improving the coil forming quality and the stability of equipment operation.

[0059] The reset assembly 400 includes multiple springs, one end of which is connected to the connecting part 221 and the other end of which is connected to the base plate 211. The multiple springs are symmetrically distributed on opposite sides of the connecting part 221.

[0060] In this embodiment, two springs are provided, with the distance between the two springs gradually increasing from the direction of the rotating part 222 towards the base plate 211; in other embodiments, the number of springs can be adjusted as needed, for example, four springs can be provided, and the four springs can be distributed in pairs on opposite sides of the connecting part 221.

[0061] By adopting the above technical solution and using springs, the structure is simple and compact, and easy to install. Two springs are symmetrically distributed on both sides of the connecting part 221, and the force is balanced and stable. They can provide uniform elastic tension or pressure when the connecting part 221 is driven to rotate by the coil, so as to realize flexible adaptive deflection. They can also quickly and smoothly drive the connecting part 221 back to the initial state after the coil passes through, so as to ensure continuous and reliable flexible support for the coil. At the same time, the spring elasticity is moderate and will not cause rigid impact to the coil, effectively preventing the pipe from deforming and jamming, and improving the working stability and adaptability of the support mechanism.

[0062] In other embodiments, the reset assembly 400 may also use an elastic rubber block, a torsion spring, or a spring sheet. The elastic rubber block achieves reset through its own compression and rebound, resulting in a quiet structure and good buffering effect. The torsion spring can be directly fitted onto the shaft of the connecting part 221, providing stable torque output and rapid reset response. The spring sheet occupies little space and is suitable for scenarios with compact installation space.

[0063] In this embodiment, connecting blocks are provided on both the connecting part 221 and the base plate 211 at the position where the spring ends. The connecting blocks are provided with connecting holes, and the ends of the springs are provided with hooks. The hooks are used to engage or disengage with the connecting holes. The springs are detachably connected by using hooks to engage with the connecting holes. During assembly, the hooks are simply inserted into the connecting holes to complete the fixation. During disassembly, they can also be easily detached. The assembly and disassembly are simple and efficient, and it is convenient to quickly replace springs with different elastic coefficients according to the coil specifications and support requirements. At the same time, the connection is firm and reliable, and it is not easy to loosen during the operation of the support mechanism. It also facilitates the maintenance, repair or replacement of the springs in the later stage, improves the applicability and maintenance convenience of the support mechanism, and extends the service life.

[0064] The lifting assembly 300 includes a screw 310, a nut 320, and a drive member 330. One end of the screw 310 is connected to the support assembly 200, and the other end of the screw 310 passes through the frame 100. The nut 320 is threadedly connected to the screw 310. The drive member 330 is connected to the frame 100 and is used to drive the nut 320 to rotate so that the screw 310 drives the support assembly 200 to lift.

[0065] In this embodiment, one end of the screw 310 is fixedly connected to the base plate 211 of the support assembly 200, and the other end of the screw 310 is inserted through the second connecting plate 140 of the frame 100. The driving member 330 is connected to the side of the second connecting plate 140 of the frame 100 facing the base plate 211.

[0066] By adopting the above technical solution, the drive component 330 drives the nut 320 to rotate. Since the screw 310 is connected to the support component 200, the screw 310 cannot rotate synchronously with the nut 320. Under the action of thread meshing, the rotational motion of the nut 320 will be converted into the linear motion of the screw 310 along its own axis. Then, the screw 310 drives the base plate 211 and the entire support component 200 to rise and fall stably along the frame 100. The threaded transmission structure of the screw 310 and the nut 320 has high transmission accuracy and good self-locking performance. It can accurately control the height position of the support component 200, ensuring accurate and reliable adjustment of the coil pitch. At the same time, the thread meshing force is uniform and the load-bearing capacity is strong. When supporting the tray tube and adjusting the height, the operation is smooth and without swaying. Fine adjustment and fixed-point positioning can be achieved, effectively improving the pitch forming accuracy and the stability of the mechanism operation.

[0067] In this embodiment, the driving component 330 is a motor, a hand crank, a servo motor, or a geared motor. Using a motor as the driving component 330 enables automated control and high adjustment efficiency. The hand crank can meet the needs of manual fine-tuning, providing intuitive operation and low cost. The servo motor can achieve precise speed and displacement control, making the height adjustment of the support component 200 more accurate. The geared motor can provide stable torque, ensuring a smooth and powerful lifting process. The overall design can be flexibly selected according to production conditions, meeting both the needs of automation and high-precision adjustment, while also taking into account the convenience of manual operation, making pitch adjustment more flexible and reliable.

[0068] The support mechanism also includes an adjustment component 500. The frame 100 is connected to the adjustment component 500, which is used to drive the frame 100 to move in order to adjust the distance between the frame 100 and the coil equipment.

[0069] In this embodiment, the adjustment component 500 is used to drive the frame 100 closer to or further away from the coiling equipment to adjust the distance between the frame 100 and the coiling equipment.

[0070] By adopting the above technical solution, the frame 100 is moved by adjusting component 500, and the distance between frame 100 and coil equipment is adjusted. When the coil needs to be supported for pitch adjustment, the frame 100 is moved closer to the coil equipment so that the support component 200 accurately receives the discharged coil to ensure the forming effect. When no support is needed or when equipment switching or maintenance is required, the frame 100 is moved away from the coil equipment to leave sufficient operating space and prevent interference. This not only ensures accurate and reliable support positioning during coil production, but also improves the flexibility of equipment layout and process switching, facilitates maintenance, mold changing, and production switching of different specifications of coils, and improves overall production adaptability and ease of use.

[0071] The adjustment assembly 500 includes a plate 510 and an adjustment member 520. The frame 100 is slidably connected to the plate 510, and the adjustment member 520 is connected to the plate 510. The adjustment member 520 is used to drive the frame 100 to move on the plate 510 to adjust the distance between the frame 100 and the coil equipment.

[0072] By adopting the above technical solution, the frame 100 slides smoothly along the plate 510. The frame 100 is driven to move by the adjusting component 520, which can accurately and stably adjust the distance between the frame 100 and the coil equipment. The structure is simple and reliable, and the transmission is smooth. It can quickly move the support mechanism to a suitable position during production to ensure effective support for the coil. It can also move the frame 100 away during shutdown, mold change or maintenance to prevent interference. At the same time, the overall guidance is good and it is not easy to deviate or shake during the movement, which further improves the flexibility of use and adaptability of the support mechanism.

[0073] In this embodiment, rails 511 are provided on the plate 510 and on both sides of the plate 510. The first connecting plate 110 of the frame 100 is provided with sliding blocks 150 that are snapped onto and slidably connected to the rails 511 on both sides. The frame 100 is slidably connected to the plate 510 through the sliding blocks 150 and the rails 511.

[0074] In this embodiment, the adjusting component 520 is an electric cylinder, a pneumatic cylinder, or a lead screw motor; using an electric cylinder or a lead screw motor can achieve automatic and precise positioning control, with fast adjustment response and high positioning accuracy, which facilitates the automated control of the distance between the frame 100 and the coil equipment; the pneumatic cylinder has rapid action and simple structure, and can quickly push and pull the frame 100 to achieve switching between near and far.

[0075] The support mechanism also includes a protective plate 600. The adjusting component 520 includes a main body 521 and a driving end 522. The main body 521 is connected to the plate 510. A connecting component 160 is provided between the driving end 522 and the frame 100. The protective plate 600 is connected to the plate 510 and is used to cover part of the driving end 522 and part of the connecting component 160.

[0076] By adopting the above technical solution, the protective plate 600 covers the drive end 522 of the adjusting component 520 and the connecting component 160, which can isolate external trampling, collision and dust, debris falling in and other interference, prevent the drive end 522 and the connecting component 160 from being deformed, displaced or damaged due to accidental trampling or collision, ensure that the drive transmission structure is always in a stable and reliable working state, reduce the operation failure caused by foreign object jamming, and extend the service life of the adjusting component 500.

[0077] In this embodiment, the connector 160 includes a drive plate 161 and a drive rod 162. The drive plate 161 is connected to the drive end 522. The drive rod 162 is provided on both sides of the drive plate 161. The drive rod 162 is parallel to the drive end 522. The end of the drive rod 162 away from the drive plate 161 is connected to the first connecting plate 110 of the frame 100. The presence of drive rods 162 on both sides of the drive plate 161 allows the driving force of the adjusting component 520 to be evenly distributed on both sides of the frame 100. This ensures that the frame 100 is subjected to balanced force and stable guidance when moving on the plate 510, preventing the skew, jamming, or shaking that can easily occur with unilateral drive. This ensures that the frame 100 moves smoothly as a whole, thereby ensuring that the relative position of the support component 200 and the coil equipment is accurately consistent, improving the reliability of the spacing adjustment and the support accuracy during coil forming.

[0078] like Figure 5 As shown, this application embodiment also provides a coiling device, including a frame 700, a forming mold 800, a feeding mechanism 900, and a support mechanism of any of the above embodiments. The feeding mechanism 900 and the forming mold 800 are both connected to the frame 700. The feeding mechanism 900 is used to drive the pipe to move, and the forming mold 800 is used to bend and form the pipe. The frame 100 of the support mechanism is arranged at the discharge end of the forming mold 800.

[0079] The specific structure of the support mechanism has been described in detail in the above embodiments and will not be repeated here.

[0080] In this embodiment, the coiling equipment also includes an automatic welding machine. The unfolded length of the coil is usually more than 15 meters, and some even reach 30 meters, while the length of conventional pipes is mostly 6 meters or 10 meters. Pipes longer than 10 meters require special transportation, which would increase costs. Therefore, the coil needs to be made by splicing multiple sections of pipe. During production, the pipes are first butt-welded by the automatic welding machine. The welded parts are flat and without protrusions, and can be directly fed into the coiling equipment for subsequent spiral forming processing without additional grinding.

[0081] The forming mold 800 includes a left bending mold and a right bending mold. The left bending mold is a double-layer clamping bending mold, and the right bending mold includes an upper push-bending disc mold and a lower clamping bending mold. The feeding mechanism 900 includes a sleeve and a servo motor. The sleeve has clamping and rotating functions and is used to transport and drive the pipe to rotate. The pipe bending head integrates the left bending mold and the right bending mold, which can realize sinking, lifting and rotating switching of the work position. The forming mold 800 is existing technology, and its specific structure will not be described in detail.

[0082] During operation, in the initial state, the bending head aligns the lower die opening of the left bending die with the 900 sleeve conveying port of the feeding mechanism. After the pipe is manually fed in, the left bending die completes the first left bend. Then, the sleeve clamps the pipe, the left bending die opens, the bending head lowers and rotates to the right bending die position, and at the same time, the sleeve drives the pipe to rotate clockwise at a set angle to determine the tilting height. After that, the bending head rises, causing the upper push-bending disc die of the right bending die to clamp the pipe. Then, the servo motor drives the sleeve to push the pipe forward. During the pushing process, the sleeve rotates counterclockwise according to preset parameters. Under the combined action of the upper and lower dies of the right bending die, the pipe is bent and shaped, forming a special-shaped coil with a tilting structure with the support mechanism, realizing continuous bending and pitch control.

[0083] The coiling equipment provided in this application, by setting up a support mechanism, supports the coil by rollers 212 and rotating parts 222 during continuous material discharge and forming. The drive component 330 drives the nut 320 to rotate, causing the screw 310 to move the base plate 211 up and down, thereby changing the height difference between the rollers 212 and the discharge end of the coiling equipment. A larger height difference results in a larger pitch between the spiral sections of the coil, while a smaller height difference results in a smaller pitch. The height of the base plate 211 can also be adjusted in real time during the discharge process to allow the same coil to form different pitches. During the process, the rollers 212 and the rotating part 222 rotate synchronously. The connecting part 221 rotates adaptively and resets under the action of the spring, maintaining smooth movement of the coil without jamming or scratching. At the same time, the frame 100 can be moved along the plate 510 through the adjusting part 520. When support is needed, it moves closer to the equipment, and when no support is needed, it moves away from it. The pitch adjustment is completed directly while the coil is being bent and formed. There is no need to transfer the formed coil to other equipment for secondary processing, reducing process transfer and waiting time and improving the production efficiency of the coil.
