Technical Field

[0002] Internally threaded copper tube heat treatment equipment is a specialized industrial device used to heat treat internally threaded copper tubes. Using electromagnetic induction, resistance heating, or gas heating, it achieves rapid and uniform heating of the tubes. Annealing and quenching, among other heat treatment processes, are performed within precisely controlled temperatures and timeframes to improve the tubes' mechanical properties, internal structure, and surface quality, meeting the demand for high-performance copper tubes in applications such as refrigeration and heat exchange. This equipment is typically equipped with an automated control system to ensure the efficiency, stability, and repeatability of the heat treatment process.

[0003] At present, the demand for high-density internally threaded copper tubes is growing in many industrial fields, and the requirements for their heat treatment quality are becoming increasingly stringent. However, the existing heat treatment equipment for high-density internally threaded copper tubes has obvious deficiencies at the technical level: first, the support and positioning devices of the equipment lack flexibility, making it difficult to adapt to the rapid replacement and precise positioning of copper tubes of different sizes, resulting in low heat treatment efficiency and unstable quality; second, the equipment fails to realize the rotation function when conveying the internally threaded copper tubes, causing the copper tubes to be heated unevenly during the heating process, seriously affecting the heat treatment effect; third, due to the lack of an effective temperature control mechanism, the copper tubes are prone to overheating during the heat treatment process, which in turn leads to bending and deformation, reducing the yield; finally, the equipment has not yet been equipped with a rapid cooling system, resulting in the copper tubes being unable to cool down in time after heat treatment, which not only prolongs the production cycle, but may also cause subsequent problems such as performance degradation or deformation of the copper tubes. Summary of the Invention

[0021] The beneficial effects of the present invention are:

[0022] The present invention effectively avoids uneven heating caused by inaccurate positioning through the support and positioning mechanism. During use, the drive mechanism drives the turntable to rotate via the third transmission assembly, and the guide column moves along the arc-shaped groove trajectory, driving the connecting plate and positioning seat to synchronously extend and retract along the radial direction of the slide rail. As the diameter of the copper tube changes, the rotation angle of the turntable can accurately adjust the spacing of the positioning wheels. The second synchronous motor drives the positioning wheels to rotate with the copper tube, forming a dynamic support, ensuring that the copper tube is heated evenly during heating, thereby improving heat treatment efficiency and quality stability.

[0023] The present invention effectively avoids the problem of reduced yield due to deformation after heating by providing a correction mechanism. When in use, the driving mechanism drives the threaded rod to rotate through the second bevel gear, and the first transmission assembly causes the two threaded rods to rotate synchronously, driving the correction top frame to rise and fall vertically. At this time, the heated internally threaded copper tube can be corrected, and the shape of the copper tube can be accurately adjusted, thereby avoiding the problem of deformation of the internally threaded copper tube.

[0024] The present invention effectively avoids the problem of performance degradation or deformation of the copper tube caused by the inability to cool down in time after heat treatment by providing a cooling component. When in use, the circulating pump pumps the low-temperature coolant in the cooling box into the circulating pipe, and the coolant is diverted to the inside of the correction base and the correction top frame. The hollow structure of the correction base and the correction top frame is built with a curved copper plate. The coolant transmits the cold temperature to the curved copper plate. The refrigerated curved copper plate directly absorbs the heat on the surface of the copper tube. The high-temperature coolant returns to the cooling box and is cooled by the heat exchanger before being recycled. This avoids the problem of performance degradation or deformation of the copper tube caused by the inability to cool down in time after heat treatment, shortens the production cycle, and improves production efficiency.

[0025] The present invention effectively avoids the problem of uneven heating caused by the failure to realize the rotation function during the conveying process through the provided conveying mechanism. When in use, the driving mechanism drives the bidirectional screw to rotate through the first bevel gear, and the symmetrical moving seat adaptively adjusts the spacing according to the diameter of the copper tube. The first synchronous motor drives the conveying wheel to rotate, and the rotating wheel contacts the outer wall of the copper tube and drives its axial feed and circumferential rotation. The copper tube maintains a uniform rotation when passing through the disc-shaped induction heating coil, so that the induced eddy current is evenly distributed, eliminating the risk of unilateral overheating, and further ensuring the stability and safety of the copper tube during transportation, thereby improving the heat treatment effect and product quality.

[0026] The present invention effectively avoids the problems of asynchronous movement and high energy consumption caused by the independent driving of multiple mechanisms through the provided driving mechanism. When in use, the third synchronous motor drives the driving shaft to rotate through the second transmission assembly, the third bevel gear on the left engages with the first bevel gear to control the conveying speed of the conveying mechanism, and the third bevel gear on the right engages with the second bevel gear to control the clamping height of the correction mechanism. At the same time, the third transmission assembly links the turntable to adjust the support positioning mechanism. Therefore, the device ensures the synchronization of the conveying speed, support positioning spacing and correction clamping force through the design of single-motor multi-stage transmission, thereby improving the operating efficiency and product quality of the entire heat treatment equipment.

The driving mechanism drives the bidirectional screw to rotate through the first bevel gear. The symmetrical moving seat adaptively adjusts the spacing according to the diameter of the copper tube. The first synchronous motor drives the conveying wheel to rotate. The rotating wheel contacts the outer wall of the copper tube and drives it to feed axially and rotate circumferentially. The copper tube maintains a uniform rotation when passing through the disc-shaped induction heating coil, so that the induced eddy current is evenly distributed, eliminating the risk of unilateral overheating.

[0040] The supporting and positioning mechanism 4 is installed on the top of the workbench 1 near the conveying mechanism 3, and is used to realize the positioning and support of internally threaded copper tubes of different diameters, wherein the supporting and positioning mechanism 4 includes a first circular frame 401 installed on the top of the workbench 1, and a second circular frame 403 fixed to the first circular frame 401 through a connecting column 402, a turntable 411 is rotatably provided at one end of the second circular frame 403, and an arc groove 412 is provided in a circular shape inside the turntable 411, a positioning rotation assembly is installed on one side of the first circular frame 401 and one side of the second circular frame 403, a connecting plate 409 is fixed on one side of the positioning seat 405 in the positioning rotation assembly, and the positioning rotation assembly includes a circular fixed The first circular frame 401 and the second circular frame 403 have a slide rail 404 on one side, and a positioning seat 405 is movably provided on the outer side of the slide rail 404. The front end of the positioning seat 405 is rotatably provided with a positioning wheel 406.

A transmission cylinder 413 connected to the drive mechanism 8 is fixedly provided on one side of the turntable 411. The drive mechanism drives the turntable to rotate through the third transmission assembly. The guide post moves along the arc groove trajectory, driving the connecting plate and the positioning seat to synchronously expand and contract along the radial direction of the slide rail. When the diameter of the copper tube changes, the rotation angle of the turntable can accurately adjust the spacing of the positioning wheels. The second synchronous motor drives the positioning wheels to rotate with the copper tube, forming a dynamic support, ensuring that the copper tube can be heated evenly during heating.

[0041] The correction mechanism 6 is installed on the front end side of the heating coil on the workbench 1, and is used to prevent the internal threaded copper tube from deforming after heating. The correction mechanism 6 includes a correction base frame 601 fixed to the top of the workbench 1, and a threaded rod 602 is symmetrically rotated on one side of the inner side of the correction base frame 601.

A second bevel gear 607 connected for transmission through the driving mechanism 8 is fixed to the bottom of the right threaded rod 602. The driving mechanism drives the threaded rod to rotate through the second bevel gear. The first transmission assembly causes the two threaded rods to rotate synchronously, driving the correction top frame to rise and fall vertically. At this time, the heated internal threaded copper tube can be corrected, and the shape of the copper tube can be accurately adjusted.

[0042] The cooling assembly 7 is installed on one side of the workbench 1 close to the correction mechanism 6, and is used to cool the corrected internally threaded copper tube. The cooling assembly 7 includes a cooling box 701, a circulating pump 702 and a circulating pipe 703. The circulating pump pumps the low-temperature coolant in the cooling box into the circulating pipe, and the coolant is diverted to the inside of the correction base frame and the correction top frame. The hollow structure of the correction base frame and the correction top frame has a built-in curved copper plate. The coolant transfers the cold temperature to the curved copper plate. The refrigerated curved copper plate directly absorbs the heat on the surface of the copper tube. The high-temperature coolant returns to the cooling box and is cooled by the heat exchanger and then recycled, thereby avoiding the problem of copper tube performance degradation or deformation caused by failure to cool down in time after heat treatment.

The driving mechanism 8 includes a driving shaft 801 and a third synchronous motor 805. The driving shaft 801 is fixed to the conveying frame 301 in the conveying mechanism 3 through the first bearing seat 802. Both ends of the driving shaft 801 are fixed with a third bevel gear 803.

The third bevel gear 803 on the right is meshed with the second bevel gear 607 in the correction mechanism 6 for transmission. A second transmission component 804 is provided for intermediate transmission, and a third transmission component 806 is provided for transmission between the output end of the third synchronous motor 805 and the turntable 411 in the support and positioning mechanism 4. The third synchronous motor drives the drive shaft to rotate through the second transmission component, and the third bevel gear on the left engages with the first bevel gear to control the conveying speed of the conveying mechanism, and the third bevel gear on the right engages with the second bevel gear to control the clamping height of the correction mechanism. At the same time, the third transmission component links the turntable to adjust the support and positioning mechanism.

The first transmission assembly 606 is composed of a pulley and a belt, which realizes smooth transmission and efficient operation of each component.

[0045] Example 2: The interiors of the correction base frame 601 and the correction top frame 603 are both hollow structures, which effectively reduces the overall weight and enhances the heat dissipation performance. The contact ends of the correction base frame 601 and the correction top frame 603 with the internal threaded copper tube are fixed with arc-shaped copper plates 605, ensuring a good fit with the copper tube and improving the accuracy of correction. The cooling box 701, the circulation pump 702, the correction base frame 601 and the correction top frame 603 are all connected by a circulation pipe 703, so that the coolant can circulate quickly, effectively taking away the heat generated during the heat treatment process, preventing the copper tube from overheating and deformation, and ensuring the stability and consistency of the heat treatment effect.

[0046] Example 3: The third synchronous motor 805 is fixedly arranged on one side of the second circular frame 403 in the supporting positioning mechanism 4, providing a stable and precise driving force for the equipment. The second transmission assembly 804 and the third transmission assembly 806 are both composed of pulleys and belts, realizing efficient power transmission.

[0047] Working principle: First, the disc-shaped induction heating coil 5 on the workbench 1 heats the copper tube. The bidirectional screw 302 in the conveying mechanism 3 rotates under the drive of the driving mechanism 8, driving the moving seat 303 to move symmetrically, and adaptively adjusting the spacing according to the diameter of the copper tube. The first synchronous motor 304 drives the conveying wheel 305 to rotate, and the rotating wheel 306 contacts the outer wall of the copper tube to realize the axial feeding and circumferential rotation of the copper tube, ensuring that the copper tube maintains a uniform rotation speed during heating, so that the induced eddy current is evenly distributed, eliminating the risk of unilateral overheating, and the turntable 411 in the support positioning mechanism 4 rotates under the drive of the third synchronous motor 805. Through the guide column 410, the connecting plate 409 and the positioning seat 405 are driven to synchronously extend and retract along the radial direction of the slide rail 404, and the spacing of the positioning wheel 406 is accurately adjusted to achieve copper tubes of different diameters. Dynamic support ensures uniform heating. The correction base frame 601 and the correction top frame 603 in the correction mechanism 6 are vertically lifted and lowered by the rotation of the threaded rod 602, and the heated copper tube is accurately corrected. The cooling component 7 pumps the coolant into the hollow structure of the correction base frame and the correction top frame through the circulating pump 702. The arc-shaped copper plate 605 directly absorbs the heat on the surface of the copper tube to achieve rapid cooling and prevent deformation. The third synchronous motor 805 in the driving mechanism 8 drives the driving shaft 801 to rotate through the second transmission component 804 and the third transmission component 806, realizing the synchronous movement of the conveying mechanism, the support and positioning mechanism and the correction mechanism, ensuring the coordination and efficiency of the entire heat treatment process. The central control device 2 monitors and adjusts the entire process to ensure stable operation of the equipment and product quality.
