Description

Technical Field

[0001] This invention belongs to the field of material processing and forming technology, specifically relating to a double-helix copper tube coiling machine and its process. Background Technology

[0002] Existing spiral coil technology suffers from several key shortcomings, with core issues concentrated in coiling types, equipment processes, structural design, and operational controls: First, the coiling types are limited and lack complete equipment support. Current technology is primarily limited to single-spiral coiling, lacking the process technology and equipment for simultaneous coiling of double spirals or multiple spirals. Furthermore, the overall focus is only on the local principles and methods of spiral copper tube bending, without a systematic description of complete production equipment, resulting in a lack of process completeness. Second, unreasonable structural design leads to a series of processing problems. The spiral grooves carved into the cylindrical shaft are difficult to process, prone to groove jumping failures, and the retraction of the tube after processing is difficult to disassemble due to the restriction of the groove body. The movable sleeve also lacks lubrication. The sliding and guiding mechanism, which relies on the hammer to bend the tube, not only easily causes deformation of the copper tube and the spiral groove edge, but also leads to uneven and discontinuous bending effect. At the same time, the spiral sleeve tooling has too many spiral turns, resulting in high resistance along the bending process and severe deformation of the finished product cross-section. It is only suitable for short-turn, low-precision workpieces and cannot meet the needs of ultra-long or high-precision coiling. Thirdly, the power drive and operation design has significant defects. Lathes are generally used as the clamping and power drive devices, and their torque is not adjustable. When the copper tube jumps out of the groove or gets stuck, it cannot stop automatically, which is prone to failure. Moreover, the workpiece must be loaded and unloaded manually. It is not possible to move the workpiece laterally to directly remove it, which is cumbersome and inefficient. Summary of the Invention

[0046] Referring to Figure 1 , Figure 2 , Figures 6-17 , the installation of the copper pipe disc manufacturing tooling before manufacturing includes the installation of the polished shaft 12, the spiral sleeve jig 13, the profiling tool 14, the lubricating component 56, the first stroke switch 43, the second stroke switch 44, and the feeding trolley 15. During the first installation, the corresponding specifications of the polished shaft 12, the spiral sleeve jig 13, the feeding trolley 15, and other tools are selected and matched with the spiral pipe disc manufacturing tool 5 for initial assembly. First, the polished shaft 12 is installed on the power head mechanism 3. The polished shaft 12 is hoisted and inserted into the installation position of the power head mechanism 3, and the hydraulic claw assembly 36 on the power head mechanism 3 is tightened. The spiral sleeve jig 13 and the profiling tool 14 are sleeved on the polished shaft 12.

Finally, a corresponding number of two copper pipe discs 16 are installed on the feeding trolley 15, axially limited and locked, and the initial installation is completed.

[0047] Referring to Figures 1-3 , Figures 9-17, the end face of the profiled tool 14 opposite to the spiral sleeve fixture 13 is in contact with the spiral surface. The two copper tubes 16 pass through the lubricating guide module 20, extend from the spiral sleeve fixture 13, and are measured for the extension length. The profiled tool 14 is used to press the copper tube 16 along the spiral direction to form a profile. Then the tube locking tool 7 is used to lock the copper tube 16 on the optical shaft 12. The lubricating guide module 20 is aligned in the direction of rotation of the spiral sleeve fixture 13. After the head of the copper tube 16 is profiled, the tube locking tool 7 is used to lock the copper tube 16 on the optical shaft 12. The operating equipment is used to make the optical shaft 12 rotate in the positive direction or in the reverse direction along the spiral line, drive the copper tube 16 to rotate along the spiral groove of the spiral sleeve fixture 13, and at the same time, the spiral sleeve fixture 13 slides forward along the spiral rise angle, so as to form a continuous spiral tube disc forming process.

[0048] Referring to Figures 1-3 , Figures 9-14 , the lubricating guide module 40 is provided with a mounting hole, a nylon oil cup 47 is mounted, an oil box 48 is mounted on the bracket above the nylon oil cup 47, and the cutting fluid bamboo joint pipe 49 with an adjusting valve is used to drain to the nylon oil cup 47, and the flow is adjusted to an appropriate flow. During the copper tube disc forming process, the lubricating oil automatically flows into the two guide holes and the outer wall of the copper tube to fully lubricate. The copper tube 16 after immersion is fully lubricated in the spiral guide disc forming process of the spiral sleeve fixture 13 and the spiral groove 46, so as to reduce the grinding resistance of the outer wall of the copper tube. It can reduce the torque of the optical shaft 14 during the disc forming process, reduce the tensile deformation and mechanical wear of the copper tube 16 during the disc forming process. That is, a very effective lubrication process is realized during the copper tube disc forming process.

[0049] Referring to Figures 1-5 , Figures 12-17 , in order to realize the continuous feeding process, a feeding trolley 15 is designed. The feeding trolley 15 is designed with a rotating shaft 50 supported by double bearings, a corresponding number of copper tubes 16 are clamped according to the number of spiral lines, and the axial displacement of the copper tube disc is limited by limiting. The copper tube 16 is manually pushed on the track to move axially, and the copper tube on the trolley is slowly rotated and expanded by traction. Thus, the process of feeding and conveying multiple copper tube discs 16 is realized.

[0050] Referring to Figures 1-5To ensure the consistency of the length of the copper pipe 16, a first travel switch 43 is installed at one end of the frame 1, the first travel switch 43 is associated with the rotary feed main oil circuit electromagnetic valve 42 of the power head mechanism 3, the first travel switch 43 is installed by several magnetic type magnets. The edge of the machine is marked with a scale mark every 1 meter distance to measure the length of the spiral pipe, when the travel switch is installed, the relative installation position is measured by the adjacent scale line, and the first travel switch 43 is fixed on the edge of the frame 1. When the lengthening arm 39 of the spiral sleeve jig 13 touches the first travel switch 43, the electromagnetic valve 42 is switched to the blocking valve position, and the power head mechanism 3 is automatically stopped rotating. The rotary proportional valve operating rod 24 is operated to the stop position, and the operating rod 45 is loaded to the empty position. The copper pipe 16 is cut off to measure 200mm in length from the inlet of the lubrication guide module 20, and the tail copper pipe 16 is rotated out by lifting the lengthening arm 39 of the spiral sleeve 13, that is, the length of the double spiral copper pipe 57 to be coiled is obtained.

[0051] Referring to Figures 1-3 , the tool mounting and dismounting operation in the continuous operation coiling process of the same specification spiral copper pipe 16. Each set of spiral copper pipe 16 coiling only needs to repeat the operation of the die tool 14, the dismounting on the light shaft 12, the operation of the tail seat sliding operating rod 8 to align the light shaft 12 and the end limit of the center 9, separation, displacement, homing, the pipe locking tool 7 is locked by two screws after pressing, and can be removed after coiling.

[0052] Working principle: through the cooperation of each mechanism to realize accurate coiling, efficient loading and unloading and safe operation: first, in the coiling forming link, the copper pipe 16 is preprocessed by the lubrication guide mechanism to complete sufficient lubrication and axis alignment, and then is formed into an adaptive arc by the profiling tool 14 along the spiral groove of the spiral sleeve jig 13, and then is fixed to the optical shaft by the pipe locking mechanism, after the electric control system switches to the loading state, the power head drives the optical shaft 12 to rotate, driving the spiral sleeve jig 13 to slide along the optical shaft 12 in a spiral line, while the feeding trolley 15 translates with it and continuously feeds, so that the copper pipe 16 is rotated into the spiral groove to form a double spiral structure, when the lengthening arm 39 of the spiral sleeve jig 13 touches the first level limit switch, the power head stops to realize length positioning; after the forming is completed, the pipe locking mechanism is removed, the tail seat center 9 is separated from the optical shaft 12 and the profiling tool 14 is taken off, the power head drives the optical shaft 12 to move to the pipe unloading position to take out the formed copper pipe, then the optical shaft is reset, the profiling tool 14 is reassembled and calibrated by the shaft alignment mechanism, the tail seat center 9 is tightly pressed against the optical shaft 12 to complete the reset preparation for the next coiling; the hierarchical limit mechanism is adopted for safety protection, the first level limit realizes normal forming positioning stop, and the second level limit is used as fault redundancy protection, when the spiral sleeve jig 13 over-travels and touches, the oil pump motor power is immediately cut off to realize global emergency stop; during the whole process, the electric control system coordinates the lubrication guide, profiling, power transmission, feeding, loading and unloading and limiting systems, through the cooperation of "low-resistance precise preposition-power forming continuous-loading and unloading reference reuse-hierarchical safety control", the double spiral copper pipe automatic, precise and safe production is achieved.

[0053] In addition, the double spiral copper pipe coiling process provided by the embodiment of the present application is completed by using a double spiral copper pipe coiling machine device, and comprises the following steps: S1: loading raw copper pipe 16 by the feeding trolley 15 of the double spiral copper pipe coiling machine, and then uniformly conveying the copper pipe 16 to the spiral sleeve jig 13 at a preset speed; S2: double spiral forming, precisely spirally forming the copper pipe 16 conveyed to the spiral sleeve jig 13 by the feeding trolley 15 in S1 according to preset pitch, spiral diameter and spiral rise angle parameters; S3: after the double spiral copper pipe 57 formed in S2 is smoothly detached from the spiral sleeve jig 13, a double spiral copper pipe 57 product meeting the specifications is obtained.

[0054] In summary, the present application is aimed at the existing spiral coil technology disc type single (only single spiral), no complete equipment support, unreasonable structure design (such as shaft spiral groove processing difficult, inconvenient pipe, no lubrication of active set leads to uneven deformation), power drive and operation defects (torque is not adjustable, no automatic parking, low efficiency of manual loading and unloading) and other problems, the device of the present application realizes the synchronous disc of double spiral copper pipe through the cooperation of lubricating guide, profiling, pipe locking and other components in the spiral coil mechanism, adjusts the torque, limits the automatic parking and realizes the precise positioning by cooperating with the control mechanism, optimizes the loading and unloading process to realize the convenient taking out of the workpiece.
