Description

Technical Field

[0001] This utility model belongs to the field of heating coil processing technology, specifically relating to a high-efficiency forming machine for heating coil processing. Background Technology

[0002] The processing of heating coils typically requires spiral bending of metal tubing to specific diameters, lengths, and pitches. Existing coil processing equipment often uses a rotating shaft to assist production, but its applicability is limited, mainly targeting coils of specific specifications. When coils of different diameters, lengths, or pitches are involved, specialized equipment often needs to be reconfigured, leading to resource waste and inefficiency. Furthermore, existing equipment can only process one coil at a time, and after processing, the coil is easily stuck on the shaft, making disassembly complex and time-consuming, increasing the workload of operators and impacting overall production efficiency. Utility Model Content

[0003] To address the problem that existing coil processing equipment is only suitable for processing coils of specific specifications, and requires the purchase of specialized equipment when processing coils of different diameters, lengths, or pitches, this invention provides a high-efficiency forming machine for heated coil processing. This equipment, by incorporating multiple sets of bending mechanisms and adjusting components, can adapt to the processing needs of coils of various specifications, while optimizing the coil disassembly process and significantly improving production efficiency.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A high-efficiency forming machine for heating coil processing mainly includes a base, a first bending unit, a second bending unit, a baffle, and a motor. The first bending unit and the second bending unit are symmetrically installed on the top of the base, and the baffle is installed on both sides of the first bending unit and the second bending unit. Each of the first bending unit and the second bending unit includes a support frame, a rotating shaft, a lifting mechanism, a guide wheel, a connecting rod, a pressing wheel, and a lifting component. The support frame is fixedly installed on the top of the base, and the rotating shaft is rotatably installed on the support frame and the baffle. The motor is installed at the bottom of the base. The two rotating shafts of the first bending unit are respectively connected to the output end of the motor through a chain drive mechanism. The two rotating shafts of the second bending unit are respectively connected to the rotating shaft of the first bending unit through gear meshing. The rotating shaft passes through the baffle and is fixedly connected to the guide wheel. The connecting rod is installed on the support frame through the lifting mechanism. The end of the connecting rod extends out of the baffle and is fixedly connected to the pressing wheel. The pressing wheel is located between the two guide wheels, and the three form a triangular structure. The lifting component is adjustablely installed on the baffle.

[0005] The lifting mechanism includes an adjusting screw, an operating handle, and a connecting plate. The adjusting screw passes through the top surface of the support frame and is mounted on the support frame via a bearing. The operating handle is fixedly mounted on the top of the adjusting screw. The connecting plate is fixedly mounted on the bottom of the adjusting screw. The connecting rod is mounted on the bottom of the connecting plate via a bearing. The pressure wheel is fixedly mounted on the end of the connecting rod. The lifting mechanism is used to adjust the distance between the pressure wheel and the guide wheel to adapt to the needs of spiral bends of coils with different diameters.

[0006] The lifting assembly includes an adjusting rod and a lifting roller. The adjusting rod is threaded onto a baffle plate, and the lifting roller is mounted on the end of the adjusting rod. Fastening bolts fix the adjusting rod to the baffle plate. The lifting assembly is used to adjust the pitch of the spiral coil.

[0007] The lifting roller is covered with a rubber layer to reduce surface wear of the spiral coil during the winding process.

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0016] This utility model discloses a high-efficiency forming machine for processing heating coils, such as... Figure 4 As shown, the high-efficiency forming machine for heating coil processing mainly includes a base 1, a first bending unit 2, a second bending unit 3, a baffle 4, and a motor 5. The base 1 is the basic support component of the entire equipment. The first bending unit 2 and the second bending unit 3 are symmetrically installed on both sides of the top of the base 1. The baffle 4 is located on the outside of the first bending unit 2 and the second bending unit 3 and is fixedly connected to the base 1. The motor 5 is installed at the bottom of the base 1 and connected to the rotating shaft 7 in the first bending unit 2 via a chain drive mechanism. Both the first bending unit 2 and the second bending unit 3 include a support frame 6, a rotating shaft 7, guide wheels 8, a pressing wheel 9, a lifting mechanism 10, and a lifting assembly 14. The support frame 6 is fixedly installed at the top of the base 1. The rotating shaft 7 is rotatably installed between the support frame 6 and the baffle 4 via bearings. The guide wheels 8 are fixedly connected to both ends of the rotating shaft 7. The lifting mechanism 10 fixes the pressing wheel 9 to the bottom of the support frame 6 via a connecting rod 13. The pressing wheel 9 is located between the two guide wheels 8 and forms a triangular layout with them. The lifting assembly 14 is mounted on the baffle 4 and is used to adjust the pitch of the coil.

[0017] The specific structures of the first bend unit 2 and the second bend unit 3 are as follows: Figure 1 , Figure 2 , Figure 3 As shown, the support frame 6 is a rectangular frame structure with a through hole at its top for installing the adjusting screw 11 of the lifting mechanism 10. The adjusting screw 11 is connected to the support frame 6 via a bearing. The operating handle 12 is fixedly installed at the top of the adjusting screw 11. The connecting plate 17 is installed at the bottom of the adjusting screw 11. The connecting rod 13 is connected to the adjusting screw 11 and located below the support frame 6. The pressure wheel 9 is installed at the end of the connecting rod 13. The rotating shaft 7 passes through the baffle 4 and is fixedly connected to the guide wheel 8. One end of the rotating shaft 7 of the first bending unit 2 is connected to the output end of the motor 5 via a chain drive mechanism, and the other end is connected to the rotating shaft 7 of the second bending unit 3 via gear meshing, thereby realizing the synchronous operation of the two bending units. When it is necessary to process coils of different diameters, the operator rotates the operating handle 12 to drive the adjusting screw 11 to rotate, thereby causing the connecting rod 13 to move in the vertical direction, adjusting the distance between the pressure wheel 9 and the guide wheel 8 to adapt to the processing requirements of coils of different diameters.

[0018] The specific structure of the lifting component 14 is as follows: Figure 1 , Figure 2 , Figure 3As shown, the adjusting rod 15 is threaded onto the baffle 4. A lifting roller 16 is mounted at the end of the adjusting rod 15. The outer surface of the lifting roller 16 is covered with a rubber layer to reduce surface wear of the coil during winding. A fastening bolt is provided on the adjusting rod 15 to secure it to the baffle 4. When the coil pitch needs adjustment, the operator loosens the fastening bolt and rotates the adjusting rod 15, moving the lifting roller 16 to the appropriate horizontal position before tightening the fastening bolt. The positional change of the lifting roller 16 directly affects the spiral rise height of the coil during processing, thus enabling flexible adjustment of the coil pitch.

[0019] In actual operation, the operator first adjusts the distance between the pressure roller 9 and the guide roller 8 of the lifting mechanism 10 according to the diameter requirement of the coil to be processed. Then, the operator adjusts the position of the lifting roller 16 of the lifting assembly 14 according to the pitch requirement of the coil. Finally, the operator starts the motor 5. The motor 5 drives the rotating shaft 7 of the first bending unit 2 to rotate through the chain drive mechanism. The rotating shaft 7 drives the guide roller 8 and the pressure roller 9 to rotate synchronously. At the same time, the rotating shaft 7 of the second bending unit 3 rotates synchronously through gear meshing, thereby realizing the simultaneous processing of the two bending units. The coil passes between the guide roller 8 and the pressure roller 9 of the first bending unit 2 and the second bending unit 3. Under the drive of the rotating shaft 7, it completes the spiral bending and forming. Finally, the lifting roller 16 guides the finished coil after the pitch adjustment. During the processing, the baffle 4 not only serves as a limit but also facilitates the installation and adjustment of the lifting assembly 14. Through the above structural design, this utility model realizes the simultaneous processing of multiple coils and can flexibly adapt to the processing needs of coils with different diameters and pitches, significantly improving production efficiency and ensuring the quality of finished products.

[0020] Work process:

[0021] In actual operation, the metal tube to be processed is first placed on the base 1, and the operator determines its diameter specification according to the design requirements of the coil. Then, by rotating the operating handle 12 in the first bending unit 2 and the second bending unit 3, the adjusting screw 11 is driven to rotate, causing the connecting rod 13 to move vertically, thereby adjusting the distance between the pressure roller 9 and the guide roller 8. This adjustment process ensures that the pressure roller 9 and the guide roller 8 can adapt to the processing requirements of coils with different diameters, while forming a stable triangular layout to ensure the stability of the coil during bending. This step utilizes the mechanical structure of the lifting mechanism 10 to achieve flexible adaptation to the coil diameter, avoiding resource waste caused by equipment replacement.

[0022] Next, the operator adjusts the position of the lifting assembly 14 according to the coil pitch requirements. Specifically, the operator loosens the fastening bolts on the adjusting rod 15, rotates the adjusting rod 15 to move it horizontally until the lifting roller 16 reaches the appropriate position, and then re-tightens the fastening bolts. The positional change of the lifting roller 16 directly affects the spiral rise height of the coil during winding, thereby achieving precise control of the pitch parameters. The rubber layer covering the outer surface of the lifting roller 16 acts as a buffer during coil winding, effectively reducing wear on the coil surface and ensuring the quality of the finished product.

[0023] After completing the above preparations, the operator starts motor 5. Motor 5 drives the rotating shaft 7 in the first bending unit 2 to rotate via a chain drive mechanism. The rotating shaft 7 drives the guide wheel 8 and the pressure wheel 9 to rotate synchronously. At the same time, the rotating shaft 7 of the second bending unit 3 rotates synchronously through gear meshing. This design enables simultaneous processing of the two bending units, significantly improving production efficiency. The metal tube passes sequentially between the guide wheel 8 and the pressure wheel 9 of the first bending unit 2 and the second bending unit 3. Driven by the rotating shaft 7, the guide wheel 8 and the pressure wheel 9 apply force to the coil, causing the coil to complete the spiral bending shape. After bending, the coil passes through the lifting roller 16 during the continued conveying process. The lifting roller 16 guides the coil according to the previously adjusted position, thereby completing the pitch adjustment and finally forming a finished coil that meets the pitch requirements. During the processing, the baffle 4 not only serves as a limit but also facilitates the installation and adjustment of the lifting assembly 14.

[0024] Through the above steps, this invention enables the simultaneous processing of multiple coils and can flexibly adapt to the processing needs of coils with different diameters and pitches. The lifting mechanism 10, by adjusting the distance between the pressure roller 9 and the guide roller 8, meets the processing requirements of coils with different diameters; the lifting assembly 14, through the combination design of the adjusting rod 15 and the lifting roller 16, achieves precise control of the coil pitch. Furthermore, the modular design of the equipment simplifies the operation process, significantly improves production efficiency, and ensures the quality of the finished product.

[0025] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
