Description

Technical Field

[0001] This invention relates to the technical field of pipe fitting processing, specifically to a spiral pipe forming equipment. Background Technology

[0002] Currently, most cars on the market are equipped with air conditioning systems, and the air conditioning pipes, as the main structure of the air conditioning system, directly affect the performance of the air conditioning system.

[0003] To improve the heat conduction of air conditioning pipes, the industry typically designs them in a spiral shape, hence the name spiral pipe. However, existing spiral pipe processing equipment is complex. It involves clamping both ends of the raw material pipe with chucks, then controlling one chuck to rotate or controlling both chucks to rotate in opposite directions, causing the raw material pipe to twist and form a spiral shape. While this method can achieve spiral pipe processing, the uneven stress on the raw material pipe during processing results in an uneven distribution of the spiral pattern and inconsistent spiral pattern size, affecting the processing quality of the spiral pipe and consequently the performance of the air conditioning equipment using it. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention aims to provide a spiral tube forming device. This device comprises several torsion mechanisms mounted on a frame, each equipped with a roller-type chuck. The roller-type chuck clamps the raw material tube to be processed. As the roller-type chuck rotates, the rollers drive the raw material tube to twist, achieving grooving. Simultaneously, each torsion mechanism corresponds to a pushing mechanism, which pushes the raw material tube relative to the roller-type chuck. This allows the extrusion rollers to move to each part of the raw material tube and extrude and twist that part, achieving spiral groove processing and forming a spiral tube. This process ensures that the spiral grooves are evenly distributed and uniform in size, improving the processing quality of the spiral tube and ensuring the performance of air conditioning equipment using this spiral tube.

[0005] The specific technical solution is as follows:

[0006] Spiral tube forming equipment has the following characteristics, including:

[0007] frame;

[0008] A torsion mechanism, several torsion mechanisms are spaced apart at one end of the frame. Each torsion mechanism includes a main shaft and a roller chuck. The main shaft is a hollow main shaft. The roller chuck is mounted on the main shaft and faces the other end of the frame. The roller chuck includes a chuck and a pressing roller. Each jaw of the chuck is equipped with a pressing roller, and the pressing rollers are all arranged facing the center of the chuck. At the same time, each pressing roller is arranged at an angle to the axial direction of the chuck.

[0009] A pushing mechanism, several pushing mechanisms are spaced apart at the other end of the frame, and one pushing mechanism corresponds to one torsion mechanism. Each pushing mechanism includes a pushing actuator and a pushing gripper. The pushing actuator is set on the frame and arranged axially along the main shaft of the corresponding torsion mechanism. The pushing actuator is equipped with a pushing gripper.

[0010] The aforementioned spiral tube forming equipment further includes several adjustment mechanisms. The adjustment mechanisms are mounted on the frame and located on the side of the torsion mechanism away from the pushing mechanism. Each adjustment mechanism corresponds to one torsion mechanism. The chuck is an automatic chuck with a hollow pull rod. The hollow pull rod passes through the hollow of the corresponding spindle and connects to the corresponding adjustment mechanism.

[0011] The aforementioned spiral tube forming equipment includes an adjusting mechanism comprising an adjusting bracket, an adjusting guide rail, an adjusting slide plate, an adjusting driver, an adjusting screw, and an adjusting screw block. The adjusting bracket is mounted on the machine frame, the adjusting guide rail is mounted on the adjusting bracket and arranged along the axial direction of the chuck, the adjusting slide plate slides on the adjusting guide rail, the adjusting screw is rotatably mounted on the adjusting bracket and arranged parallel to the adjusting guide rail, and the adjusting screw block is threaded onto the adjusting screw and connected to the adjusting slide plate. The adjusting driver is mounted on the adjusting bracket and poweredly connected to the adjusting screw, and one end of the hollow pull rod extending out of the hollow part of the main shaft is rotatably mounted on the adjusting slide plate.

[0012] The aforementioned spiral tube forming equipment further includes a transfer mechanism. The transfer mechanism is mounted on the frame and positioned horizontally above the torsion mechanism and the pushing mechanism. The transfer mechanism includes a transfer bracket, a transfer guide rail, a transfer slide plate, a translation actuator, a lifting actuator, a mounting rod, and several transfer grippers. The lower end of the transfer bracket is mounted on the frame, and the upper end of the transfer bracket extends vertically above the torsion mechanism and the pushing mechanism. The transfer guide rail is mounted on the upper end of the transfer bracket and extends along the arrangement direction of the several pushing mechanisms. Meanwhile, the transfer slide plate slides on the transfer guide rail. The translation actuator is mounted between the transfer bracket and the transfer slide plate and drives the transfer slide plate to reciprocate on the transfer guide rail. The lifting actuator is mounted vertically downward on the transfer slide plate. A mounting rod parallel to the transfer guide rail is mounted on the drive shaft of the lifting actuator, and several transfer grippers are spaced apart on the mounting rod, with the number of transfer grippers exceeding the number of pushing mechanisms.

[0013] The aforementioned spiral tube forming equipment also includes a feeding mechanism, which is located on the side of the frame. The feeding mechanism and several pushing mechanisms are arranged equidistantly. The feeding mechanism includes a feeding bracket, a feeding component, and a positioning component. The feeding component and the positioning component are both located on the feeding bracket, and the positioning component is located between the feeding component and the pushing mechanism.

[0014] In the aforementioned spiral tube forming equipment, the feeding assembly includes a bracket, a lifting frame, and a feeding lifter. One side of both the bracket and the lifting frame is arranged in a multi-step shape, and the inner side of each step surface of the bracket and the lifting frame is lower than the outer side. Meanwhile, the bracket is installed on the feeding support and extends towards the pushing mechanism. The feeding lifter is installed on the feeding support and moves vertically. The lifting frame is installed on the feeding lifter. After the bracket and the lifting frame are installed, the step surfaces of the bracket and the lifting frame are staggered, and the step surface of the lifting frame is lower than the step surface of the bracket.

[0015] The aforementioned spiral tube forming equipment includes a positioning component comprising a placement frame, placement blocks, an end limiting plate, an end push actuator, and a positioning plate. The placement frame is mounted on the feeding support and located below the side of the highest step surface of the support. The end limiting plate and the end push actuator are respectively located at both ends of the placement frame. The end push actuator is arranged facing the end limiting plate and is equipped with a positioning plate. Several placement blocks are installed on the placement frame between the end limiting plate and the positioning plate, and each placement block has a placement groove.

[0016] The aforementioned spiral tube forming equipment includes a feeding assembly that further comprises a limiting plate, a limiting guide rail, and several limiting sliders. The limiting guide rail is mounted on the feeding bracket and arranged along the axial direction of the main shaft. Several limiting sliders slide on the limiting guide rail, and each limiting slider is equipped with a locking structure. Additionally, limiting plates are provided on the two limiting sliders at both ends of the limiting guide rail, and a bracket is installed on the limiting slider in the middle section of the limiting guide rail.

[0017] In the aforementioned spiral tube forming equipment, the width of the lowest step surface of the bracket is greater than the width of any other step surface, and the width of the second highest step surface of the bracket is second only to the width of the lowest step surface. Meanwhile, the highest step surface of the lifting frame is composed of a movable block, which includes a connecting part and a lifting part. One end of the connecting part has a strip hole, and the upper end of the frame has a locking hole corresponding to the strip hole. The locking hole and the strip hole are locked together by threaded fasteners, and the top surface of the lifting part forms the highest step surface of the lifting frame.

[0018] The aforementioned spiral tube forming equipment also includes a receiving rack, which has a receiving trough and is mounted on the frame and located on the side of the pushing mechanism away from the feeding mechanism.

[0019] The aforementioned spiral tube forming equipment further includes several auxiliary grippers, each auxiliary gripper corresponding to a torsion mechanism, and the auxiliary grippers are located between the corresponding torsion mechanism and the pushing mechanism.

[0020] The positive effects of the above technical solution are:

[0021] The aforementioned spiral tube forming equipment, by arranging several torsion mechanisms and corresponding pushing mechanisms at intervals on the frame, and by providing roller chucks for each torsion mechanism, achieves the formation of a tube end sealing groove by clamping the raw material tube to be processed and rotating it. Simultaneously, the torsion mechanism, in conjunction with the pushing mechanism, pushes the raw material tube relative to the roller chuck of the torsion mechanism. As the roller chuck rotates, the extrusion rollers cause the raw material tube to be processed to twist, and the pushing mechanism pushes the raw material tube relative to the roller chuck. This allows the extrusion rollers to move to each part of the raw material tube and extrude and twist that part, thereby forming a spiral groove on the tube wall, thus forming a spiral tube. This effectively ensures that the spiral pattern is evenly distributed and uniform in size, resulting in higher quality spiral tubes and improved performance of air conditioning equipment using these spiral tubes.

[0031] To make the technical means, creative features, objectives, and effects of this invention easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 8 The technical solutions provided by this invention are described in detail, but the following content is not intended to limit this invention.

[0032] Figure 1 This is a structural diagram of an embodiment of the spiral tube forming equipment of the present invention. Figure 1 As shown, the spiral tube forming equipment provided in this embodiment includes: a frame 1, a torsion mechanism 2, and a pushing mechanism 3.

[0033] Figure 2 This is a structural diagram of the torsion mechanism and the adjustment mechanism according to a preferred embodiment of the present invention. Figure 1 and Figure 2As shown, several torsion mechanisms 2 are provided, spaced apart at one end of the frame 1 along its width, enabling multi-station processing. This allows each station to perform individual processing or to serve as a station for secondary, tertiary, or other processing steps in the spiral tube composite processing. For example, an annular sealing groove can be machined at the end of the raw material tube 9, and then the raw material tube 9 with the end sealing groove machined can be spirally processed to meet different processing requirements. Furthermore, each torsion mechanism 2 includes a spindle 21 and a roller-type chuck 22. The spindle 21 is hollow, preferably an electric spindle 21, which ensures smooth operation and convenient control. The hollow design of the spindle 21 also facilitates the smooth passage of the pull rod of the subsequent automatic chuck 221 and the processed spiral tube. Furthermore, the roller chuck 22 is mounted on the main shaft 21 and faces the other end of the frame 1, allowing the roller chuck 22 to be driven by the main shaft 21 to rotate, providing conditions for subsequent twisting of the raw material tube 9 to be processed. The roller chuck 22 also includes a chuck 221 and pressing rollers 222. Each jaw of the chuck 221 is equipped with a pressing roller 222, meaning that the spacing between the pressing rollers 222 is adjusted by moving the jaws of the chuck 221, thereby adjusting the force exerted by the pressing rollers 222 on the raw material tube 9 to be processed, meeting different processing requirements. Moreover, the pressing rollers 222 are all arranged towards the center of the chuck 221, ensuring that the raw material tube 9 to be processed can be clamped by the pressing rollers 222, and that the clamped raw material tube 9 is positioned at the center of the chuck 221. This provides conditions for the subsequent processing of the raw material tube 9 or the processed threaded tube to avoid entering the hollow of the main shaft 21, maintaining normal equipment operation. Meanwhile, each extrusion roller 222 is arranged at an angle to the axial direction of the chuck 221. When the extrusion roller 222 is arranged at 90° to the axial direction of the chuck 221, the extrusion roller 222 forms an annular groove on the wall of the raw material tube 9 to be processed, thus realizing the processing of the tube end sealing groove. When the angle between the extrusion roller 222 and the chuck 221 is less than 90°, the extrusion roller 222 and the axial direction of the raw material tube 9 to be processed are arranged at an angle, so that the rotation of the extrusion roller 222 can adapt to the movement of the raw material tube 9 to be processed along its axial direction, thereby forming a spiral pattern on the surface of the raw material tube 9 to be processed, thus meeting the processing requirements of the spiral tube.

[0034] Figure 3 This is a structural diagram of the feeding mechanism and auxiliary gripper according to a preferred embodiment of the present invention. Figure 1 and Figure 3As shown, several pushing mechanisms 3 are spaced apart at the other end of the frame 1, and one pushing mechanism 3 corresponds to one torsion mechanism 2, so that each torsion mechanism 2 can perform a pushing operation through a pushing mechanism 3. That is, the feeding and unloading operations of the raw material tube 9 to be processed are realized through the pushing mechanism 3, so that the raw material tube 9 to be processed can move relative to the roller chuck 22 on the torsion mechanism 2, providing conditions for forming an annular sealing groove or a spiral tube at the tube end of the raw material tube 9 to be processed. In addition, each of the feeding mechanisms 3 includes a feeding actuator 31 and a feeding gripper 32. The feeding actuator 31 is mounted on the frame 1 and arranged along the axial direction of the main shaft 21 of the corresponding torsion mechanism 2. The feeding actuator 31 is equipped with a feeding gripper 32, so that the feeding actuator 31 can drive the feeding gripper 32 to approach or move away from the main shaft 21. This allows the raw material tube 9 to be processed, which is held by the feeding gripper 32, to be pushed towards the roller chuck 22, thereby realizing the processing of the spiral pattern.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, each torsion mechanism 2 also corresponds to an adjustment mechanism 4. The adjustment mechanism 4 is mounted on the frame 1 and is located on the side of the torsion mechanism 2 opposite to the pushing mechanism 3, thus preventing the adjustment structure from obstructing the movement of the pushing mechanism 3 and the raw material tube 9 to be processed. Furthermore, one adjustment mechanism 4 corresponds to one torsion mechanism 2, meaning one adjustment mechanism 4 can adjust the corresponding torsion mechanism 2. Simultaneously, the chuck 221 is an automatic chuck 221 with a hollow pull rod 41. The hollow pull rod 41 passes through the hollow of the corresponding main shaft 21 and connects to the corresponding adjustment mechanism 4. That is, the adjustment mechanism 4 can adjust the position of the jaws on the automatic chuck 221 through the hollow pull rod 41, thereby adjusting the magnitude of the force by which the pressing rollers 222 of the roller-type chuck 22 loosen or press the raw material tube 9 to be processed, and the force applied to the raw material tube 9 to be processed, meeting the requirements for loading / unloading and processing raw material tubes of different specifications. It is worth noting that the structure of the automatic chuck 221 with hollow tie rod 41 can be the same as or similar to the structure of the hydraulic cylinder driven automatic chuck 221 on existing machine tools on the market, as long as the tie rod is hollow. Therefore, its specific structure will not be described in detail here.

[0036] More specifically, the adjustment mechanism 4 includes an adjustment bracket 42, an adjustment guide rail 43, an adjustment slide plate 44, an adjustment driver 45, an adjustment screw 46, and an adjustment block 47. At this time, the adjustment bracket 42 is mounted on the frame 1, and the adjustment guide rail 43 is mounted on the adjustment bracket 42, with the adjustment guide rail 43 arranged along the axial direction of the chuck 221. The adjustment slide plate 44 is slidably mounted on the adjustment guide rail 43, thereby allowing the adjustment slide plate 44 to move along the axial direction of the chuck 221 and to move away from or towards the chuck 221. Meanwhile, the adjusting screw 46 is rotatably mounted on the adjusting bracket 42, and the adjusting screw 46 is arranged parallel to the adjusting guide rail 43, ensuring that the axial direction of the adjusting screw 46 is consistent with the moving direction of the adjusting slide plate 44. Simultaneously, the adjusting screw block 47 is threaded onto the adjusting screw 46 and connected to the adjusting slide plate 44. The adjusting driver 45 is mounted on the adjusting bracket 42, and the adjusting driver 45 is poweredly connected to the adjusting screw 46. This ensures that when the adjusting driver 45 drives the adjusting screw 46 to rotate, the adjusting screw block 47 and the adjusting screw 46... During relative rotation, the adjusting screw 47 moves axially along the adjusting lead screw 46, thereby driving the adjusting slide plate 44 to move on the adjusting guide rail 43. The end of the hollow pull rod 41 extending out of the hollow part of the main shaft 21 is rotatably mounted on the adjusting slide plate 44. This ensures the flexibility of the hollow pull rod 41 itself, and also allows the hollow pull rod 41 to move axially along the chuck 221 through the adjusting slide plate 44, thereby adjusting the position of the jaws on the chuck 221 and adjusting the tightness of the roller chuck 22 to meet different processing requirements.

[0037] Figure 4 This is a structural diagram of a transfer mechanism according to a preferred embodiment of the present invention. Figure 1 and Figure 4As shown, a transfer mechanism 5 is also provided on the large frame 1, which realizes the transfer of the raw material pipe 9 between the feeding mechanism 6 and several torsion mechanisms 2. Furthermore, the transfer mechanism 5 is set on the frame 1 and placed horizontally above the torsion mechanism 2 and the pushing mechanism 3 to prevent the transfer mechanism 5 from obstructing the operation of the torsion mechanism 2 and the pushing mechanism 3. At this time, the transfer mechanism 5 includes a transfer bracket 51, a transfer guide rail 52, a transfer slide plate 53, a translation actuator 54, a lifting actuator 55, a mounting rod 56, and several transfer grippers 57. The lower end of the transfer bracket 51 is installed on the frame 1, and the upper end of the transfer bracket 51 extends vertically above the torsion mechanism 2 and the pushing mechanism 3, so that there is a certain height difference between the upper end of the transfer bracket 51 and the frame 1. At the same time, the transfer guide rail 52 is installed on the upper end of the transfer bracket 51 and extends along the arrangement direction of several pushing mechanisms 3, so that the transfer guide rail 52 can span across the top of each pushing mechanism 3, providing conditions for the subsequent operation of the raw material pipe 9 between different pushing mechanisms 3. Meanwhile, the transfer slide plate 53 is slidably mounted on the transfer guide rail 52, and the translation actuator 54 is installed between the transfer bracket 51 and the transfer slide plate 53, driving the transfer slide plate 53 to reciprocate on the transfer guide rail 52. That is, the transfer slide plate 53 can move between different pushing mechanisms 3 under the action of the translation actuator 54. At the same time, the lifting actuator 55 is vertically mounted on the transfer slide plate 53, so that the lifting actuator 55 can follow the movement of the transfer slide plate 53. Furthermore, a mounting rod 56 parallel to the transfer guide rail 52 is mounted on the drive shaft of the lifting actuator 55, so that the mounting rod 56 can both move with the transfer slide plate 53 and be driven by the lifting actuator 55 to perform lifting and lowering movements. Thus, the mounting rod 56 can meet the combined movement in the horizontal and vertical directions. In addition, several transfer grippers 57 are arranged at intervals on the mounting rod 56, so that the transfer grippers 57 can move in the horizontal and vertical directions, meeting the needs of clamping, transferring, and unloading the raw material tube 9. The structural design is more reasonable. In addition, the number of transfer grippers 57 is greater than the number of pushing mechanisms 3. Preferably, the number of transfer grippers 57 is one more than the number of pushing mechanisms 3. That is, the extra transfer gripper 57 can be arranged between the feeding mechanism 6 and the pushing mechanism 3. The extra transfer gripper 57 can transfer the raw material pipe 9 transported by the feeding mechanism 6 to one of the pushing mechanisms 3. The remaining transfer gripper 57 can transfer the raw material pipe 9 between two adjacent pushing mechanisms 3. At the same time, the extra transfer gripper 57 can also be used for unloading, that is, to clamp the processed pipe from the pushing mechanism 3 and transport it to the receiving rack 7, which is more convenient to use.

[0038] Figure 5 This is a structural diagram of a feeding assembly according to a preferred embodiment of the present invention. Figure 1 and Figure 5As shown, a feeding mechanism 6 is also provided on the side of the frame 1. The feeding mechanism 6 is arranged equidistantly with several pushing mechanisms 3, so that the equidistantly arranged transfer grippers 57 can meet the needs of feeding and transferring the raw material tube 9 between two adjacent pushing mechanisms 3. At this time, the feeding mechanism 6 includes a feeding bracket 61, a feeding component 62, and a positioning component 63. The feeding component 62 and the positioning component 63 are both set on the feeding bracket 61, and the positioning component 63 is set between the feeding component 62 and the pushing mechanism 3. The feeding bracket 61 provides support for the feeding component 62 and the positioning component 63, and the feeding component 62 enables automatic feeding. The positioning component 63 can position the end face of the raw material tube 9 during feeding, ensuring that the position of the raw material tube 9 is more accurate during the feeding process, thereby ensuring the precision of product processing.

[0039] Figure 6 This is an installation diagram of the bracket and lifting frame according to a preferred embodiment of the present invention; Figure 7 This is a structural diagram of a lifting frame according to a preferred embodiment of the present invention. Figure 1 , Figure 5 as well as Figure 6 and Figure 7As shown, the feeding component 62 of the feeding mechanism 6 includes a bracket 621, a lifting frame 622, and a feeding lifter 623. At this time, one side of both the bracket 621 and the lifting frame 622 has a multi-step shape, and the inner side of each step of the bracket 621 and the lifting frame 622 is lower than the outer side, making each step a sloping structure with a higher outer side and a lower inner side. This allows the raw material pipe 9 placed on the step surface to automatically roll to the inner side of the step surface, providing conditions for the subsequent transfer of the raw material pipe 9 between adjacent steps. Simultaneously, the bracket 621 is installed on the feeding support 61 and extends towards the pushing mechanism 3. The highest step of the bracket 621 is the side closest to the pushing mechanism 3. The bracket 621 serves as a storage structure for the raw material pipe 9 during the feeding process. The loading lift 623 is installed on the loading bracket 61 and moves vertically upwards and downwards. The lifting frame 622 is installed on the loading lift 623, so that the lifting frame 622 can move upwards and downwards under the action of the loading lift 623. After the bracket 621 and the lifting frame 622 are installed, the stepped surfaces of the bracket 621 and the lifting frame 622 are staggered. That is, after installation, the stepped surfaces of the bracket 621 and the lifting frame 622 are staggered, and the stepped surface of the lifting frame 622 is lower than the stepped surface of the bracket 621. Preferably, the stepped surface of the platform is located on the bracket 621. At the position between two adjacent stepped surfaces of the frame 621, that is, when the lifting frame 622 is raised, the raw material pipe 9 can rise with the support of the stepped surface of the lifting frame 622. When the height of the stepped surface of the lifting frame 622 is higher than the height of the stepped surface on the bracket 621, the raw material pipe 9 can roll along the stepped surface of the lifting frame 622 to the stepped surface of the bracket 621, realizing the climbing of the raw material pipe 9 between two adjacent stepped surfaces of the bracket 621. This is repeated to transfer the raw material pipe 9 from the lowest stepped surface of the bracket 621 to the highest stepped surface, thus realizing the feeding operation.

[0040] Figure 8 This is a structural diagram of a positioning component according to a preferred embodiment of the present invention. As shown in the figure... Figure 1 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8As shown, the positioning component 63 further includes a placement frame 631, placement blocks 632, an end limiting plate 633, an end push actuator 634, and a positioning plate 635. The placement frame 631 is positioned on the feeding bracket 61 and below the side of the highest step surface of the support 621, used to receive the raw material pipe 9 rolling down from the highest step surface of the support 621. The end limiting plate 633 and the end push actuator 634 are respectively positioned at both ends of the placement frame 631. The end push actuator 634 is positioned facing the end limiting plate 633 and has the positioning plate 635 installed on it. This allows adjustment of the distance between the positioning plate 635 and the end limiting plate 633 via the end push actuator 634. Several placement blocks 632 are installed on the placement frame 631 between the end limiting plate 633 and the positioning plate 635, and each placement block 632 has a placement groove 6321. The placement groove 6321 on the placement block 632 is used to accommodate the raw material tube 9, preventing the raw material tube 9 from moving on the placement block 632 and affecting the gripping of the transfer gripper 57. At the same time, it also allows the raw material tube 9 located in the placement groove 6321 to move towards the end limiting plate 633 under the action of the end push actuator 634. The end limiting plate 633 provides a base for the raw material tube 9 in the placement groove 6321, ensuring that the end position of the raw material tube 9 can be more accurate, and providing conditions for subsequent sealing groove processing and spiral tube formation of the raw material tube 9.

[0041] More specifically, the feeding assembly 62 also includes a limiting plate 624, a limiting guide rail 625, and several limiting sliders 626. The limiting guide rail 625 is set on the feeding bracket 61 and arranged along the axial direction of the main shaft 21, so that the arrangement direction of the limiting guide rail 625 is consistent with the length direction of the raw material tube 9. At the same time, several limiting sliders 626 are slidably placed on the limiting guide rail 625, and each limiting slider 626 is provided with a locking structure, so that the limiting slider 626 can move on the limiting guide rail 625 and be locked by the locking structure. At the same time, the two limiting sliders 626 at both ends of the limiting guide rail 625 are provided with limiting plates 624. The two limiting plates 624 restrict the two ends of the raw material tube 9, which facilitates the subsequent lifting of the lifting frame 622 and also allows for the adjustment of the distance between the two limiting plates 624 to meet the feeding requirements of raw material tubes 9 of different lengths. Furthermore, a bracket 621 is installed on the limiting slider 626 in the middle section of the limiting guide rail 625, which enables the bracket 621 to be installed on the feeding bracket 61. Simultaneously, the position of the bracket 621 on the feeding bracket 61 can be adjusted to meet the processing requirements of raw material tubes 9 of different specifications. It is worth noting that the locking structure is a locking screw, which is screwed onto the limiting slider 626 with its end abutting against the limiting guide rail 625. The unlocking and locking requirements of the locking structure are met by adjusting the tightness of the locking screw.

[0042] More specifically, the width of the lowest step surface of the bracket 621 is greater than the width of any other step surface. This means the lowest step surface of the bracket 621 provides a sufficiently large storage platform, allowing the raw material pipes 9 to be stacked on the lowest step surface, thus enabling automatic feeding. At this time, the width of the second highest step surface of the bracket 621 is second only to the lowest step surface, allowing the raw material pipes 9 lifted by the lifting frame 622 to be temporarily stored on the second highest step surface. Meanwhile, the highest step surface of the lifting frame 622 is composed of a movable block, including a connecting part 6221 and a lifting part 6222. A strip-shaped hole 6223 is provided at one end of the connecting part 6221, and a locking hole corresponding to the strip-shaped hole 6223 is provided at the upper end of the platform. The locking hole and the strip-shaped hole 6223 are locked together by threaded fasteners. The top surface of the lifting part 6222 forms the highest step surface of the lifting frame 622, i.e., through… The misalignment between the highest step surface of the lifting frame 622 and the second highest step surface of the bracket 621 is achieved by adjusting the position of the strip hole 6223 and the locking hole. When the overlap between the highest step surface of the lifting frame 622 and the second highest step surface of the bracket 621 is only the diameter of the raw material pipe 9, the lifting frame 622 can lift only one raw material pipe 9 at a time. This ensures that the raw material pipe 9 entering the placement groove 6321 is a single pipe, which guarantees that the subsequent transfer gripper 57 can grasp it individually, thus ensuring the effectiveness of processing. In addition, it can also be adjusted to adapt to the feeding requirements of raw material pipes 9 with different diameters, making the structural design more reasonable.

[0043] More specifically, a receiving rack 7 is also provided on the frame 1 on the side opposite to the feeding mechanism 6 of the pushing mechanism 3. At this time, the receiving rack 7 has a receiving trough, through which the processed spiral tube is collected.

[0044] More specifically, the frame 1 is also equipped with several auxiliary grippers 8. At this time, one auxiliary gripper 8 corresponds to one torsion mechanism 2, and the auxiliary gripper 8 is located between the corresponding torsion mechanism 2 and the pushing mechanism 3. That is, when the length of the raw material tube 9 is long, the auxiliary gripper 8 can support the raw material tube 9 between the torsion mechanism 2 and the pushing mechanism 3, preventing the raw material tube 9 from falling due to excessive length, and further ensuring the processing quality of the product.

[0045] In a preferred embodiment, the regulating driver 45 is a servo motor, and the pusher actuator 31 has a structure of servo motor, lead screw, screw block, guide rail, and slide plate, which is a conventional feeding structure on the market. Similarly, the translation actuator 54 has a structure of guide rail, slide plate, servo motor, gear, and rack, which is also a conventional feeding structure on the market. The technology is mature, the operation is stable, the control is convenient, and it can improve the running accuracy. Therefore, its specific structure will not be described in detail here. In addition, the lifting actuator 55 and the loading lift 623 are telescopic cylinders, which have low manufacturing and use costs and fast response.

[0046] The spiral tube forming equipment provided in this embodiment includes a frame 1, a torsion structure, and a pushing mechanism 3. Several torsion mechanisms 2 are spaced apart on the frame 1. Each torsion mechanism 2 has a roller-type chuck 22, which clamps the raw material tube 9 to be processed. When the roller-type chuck 22 rotates, it performs grooving processing on the end sealing groove of the raw material tube 9. Furthermore, each torsion mechanism 2 corresponds to a pushing mechanism 3, which pushes the raw material tube 9 along its axial direction relative to the roller-type chuck 22. When the roller-type chuck 22 rotates, the extrusion roller 222 can move to each part of the raw material tube 9 to be processed and extrude and torsion that part, meeting the requirements of spiral tube processing. This ensures that the processed spiral pattern is evenly distributed and uniform in size, resulting in higher quality spiral tubes and improved performance of air conditioning equipment using these spiral tubes.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
