Description

Technical Field

[0001] The present invention relates to the field of heat treatment of planetary carriers, and in particular to a heat treatment device and a production method for an integrally forged planetary carrier. Background Art

[0002] As a core component of planetary gear transmissions, integrally forged planetary carriers are widely used in the automotive, aerospace, and other fields. Their performance directly impacts the reliability of the transmission system. Because they must withstand complex alternating loads and friction and wear during operation, heat treatment is a key process for improving their performance. Currently, the heating and cooling processes in planetary carrier heat treatment are significantly inadequate. Most production processes utilize separate clamping and lifting equipment for the heating and cooling stages, requiring the carrier to be disassembled and re-clamped multiple times when transferred from the heating furnace to the cooling pool. This not only consumes significant manpower and time, but also poses a high risk of surface damage and localized deformation during assembly and disassembly due to operational errors or equipment inaccuracies, impacting subsequent assembly and performance. Even if some technologies use a single clamping device to complete the entire process, it is difficult to arrange multiple lifting equipment for collaborative operation due to the limitations of the equipment space layout; in actual production, due to the compact equipment space, it is often impossible to realize the parallel operation of multiple groups of clamping equipment, and only the "single-station, sequential" operation mode can be adopted, resulting in excessively long production cycles, making it difficult to form continuous and efficient assembly line operations, and the production efficiency cannot meet the needs of industrial large-scale production.

[0003] Prior art, such as patent publication number CN217973314U, discloses a homogenizing heat treatment device for wind turbine planetary carrier castings. This device utilizes a base, a support seat, and a fixed seat to construct a support structure. A rotating seat drives the rotation of a pallet. When the planetary carrier is placed on the pallet, its own weight drives the pallet downward. The support arm and other components are linked to each other, causing the clamping arm to press against the outer edge of the planetary carrier to achieve self-clamping. A motor drives the rotating seat to rotate for uniform heating. However, while this technology has improved some of the original problems, there are still areas that require further optimization to better meet actual testing needs.

[0004] 1. The above device adopts an external clamping method, which requires installation space to be reserved on the outer periphery of the planetary carrier, resulting in a large device volume and not conducive to a compact equipment layout; and the clamping components are exposed to the heating area for a long time and are prone to aging due to high temperature, which affects the clamping stability and equipment life.

[0005] 2. The planetary frame relies on its own weight for clamping. When it needs to be placed vertically in the cooling pool, it cannot automatically detach from the clamping device and must be taken in and placed manually with the help of additional equipment, which increases the complexity and cost of the process and makes it difficult to achieve full process automation.

[0006] Therefore, based on the above-stated viewpoint, there is still room for optimization in the existing technology of heat treating the planetary carrier. Summary of the Invention

[0017] Preferably, the pushing component includes through grooves symmetrically opened on both sides of the transverse frame plate, and the upper and lower through grooves correspond to each other. Two pushing cylinders are symmetrically arranged on the bottom plate. The telescopic end of the pushing cylinder is provided with a pushing plate located between the two transverse frame plates, and the pushing plate corresponds to the upper and lower adjacent through grooves on one side.

[0018] Preferably, a plurality of protective plates located on both sides of the through slot are installed between the upper and lower corresponding transverse frame plates.

[0040] The following combination Figures 1 to 11 The embodiments of the present invention are described in detail.

[0041] The embodiment of the present application discloses a heat treatment device and production method for an integrally forged planetary carrier, which is used in the process of heat treatment of the integrally forged planetary carrier, and can perform heat treatment operations such as heating and quenching on the planetary carrier, and realize automated heat treatment of the planetary carrier through the coordinated cooperation of various components; further, the present application can also achieve the effect of step coordination by setting a transmission unit to drive the annular gear ring, the swing cylinder and the receiving screw to work, while preventing the driving equipment from being unable to work due to being baked by the temperature of the heating plate or being soaked in water in the treatment box for a long time.

[0042] Example 1: Reference Figure 1 and Figure 2 As shown, it includes a base plate 1, a support frame 10, a transverse frame plate 11, a conveyor belt 12, a rectangular frame plate 13, a drive rack 14, a clamping unit 2, a processing box 15 and a pushing assembly 6. The two transverse frame plates 11 are located on the support frame 10 and are connected to the other two transverse frame plates 11 through a connecting plate, that is, the support frame 10 can support the two transverse frame plates 11, and the lower two transverse frame plates 11 can support the upper two transverse frame plates 11 through the connecting plate.

[0043] A conveyor belt 12 is provided in the transverse frame plate 11, and a driving tooth is installed on the outside of the conveyor belt 12. Several rectangular frame plates 13 are slid between the transverse frame plates 11. Driving racks 14 that mesh with the driving teeth are provided on both sides of the rectangular frame plates 13. The conveyor belt 12 can be driven by an external driving device to move the driving teeth on its outside in the transverse frame plate 11. During the movement, the driving teeth can drive the rectangular frame plates 13 to move left and right under the limit guide of the corresponding two transverse frame plates 11 through the driving racks 14.

[0044] A clamping unit 2 for clamping the planetary carrier is provided on the rectangular frame plate 13, and two processing boxes 15 are provided between the two horizontal frame plates 11 at the lower end. A heating plate (not shown) is installed on the inner wall of the processing box 15 on one side, and water is stored in the processing box 15 on the other side. The operator can install inlet and outlet pipes on the processing box 15 on one side to achieve the purpose of supplying water or draining water inside the processing box 15.

[0045] Two pushing components 6 are symmetrically arranged on the bottom plate 1 for driving the rectangular frame plate 13 to move between the upper or lower two transverse frame plates 11 .

[0046] This application also proposes a method for producing an integral forged planet carrier, comprising the following steps: S1, planet carrier placement: the planet carrier is placed on the pushing assembly 6 on the left side, and the pushing assembly 6 drives the planet carrier to move between the corresponding rectangular frame plates 13 and is clamped by the clamping unit 2.

[0047] S2, planet carrier heating: then the rectangular frame plate 13 is indirectly driven by the conveyor belt 12 to move to the side corresponding to the processing box 15, and the clamping unit 2 drives the planet carrier into the processing box 15, and the planet carrier is heat-treated by heating the heating plate.

[0048] S3, planet carrier quenching: Finally, the rectangular frame plate 13 moves to the upper end of the next processing box 15, so that the planet carrier enters the processing box 15 and contacts the water inside the processing box for quenching.

[0049] S4, planet carrier cooling: Finally, the rectangular frame plate 13 moves to correspond to the push assembly 6 on the right side, and the push assembly 6 drives the rectangular frame plate 13 to move between the two upper transverse frame plates 11. At this time, the planet carrier can be cooled naturally.

[0050] S5, the planet carrier is removed, and after the rectangular frame plate 13 is moved to the left side of the transverse frame plate 11, it is driven between the two lower transverse frame plates 11 by the pushing assembly 6 on the left side, and the processed planet carrier is removed.

[0051] Reference Figure 2 and Figure 3As shown, it is a clamping unit 2 for clamping the planetary carrier; specifically, the clamping unit 2 includes a circular groove 20, a sliding plate 21, a clamping member 3, a limit plate 22, a driving screw 23, an annular gear ring 24 and a driving gear 25. The circular groove 20 is opened in the middle of the rectangular frame plate 13, and a number of sliding grooves that pass through the interior of the rectangular frame plate 13 are opened on the inner diameter of the circular groove 20. A sliding plate 21 slides in the sliding groove, and a clamping member 3 is provided at one end of the sliding plate 21 located in the circular groove 20. The sliding plate 21 can move in the corresponding sliding groove when driven by external force. The planetary carrier is placed in the circular groove 20, and the clamping member 3 can be driven by the sliding plate 21 to clamp the planetary carrier.

[0052] Several limit plates 22 corresponding to the sliding grooves are provided in the rectangular frame plate 13. A driving screw 23 is rotated on the limit plate 22. One side of the driving screw 23 is threadedly connected to the corresponding sliding plate 21 groove. The driving screw 23 is driven by external force and can rotate under the limit of the limit plate 22. When rotating, it can drive the corresponding sliding plate 21 to move and clamp the planetary carrier.

[0053] An L-shaped annular gear ring 24 rotates inside the rectangular frame plate 13. A driving gear 25 meshing with the annular gear ring 24 is sleeved on the outer side of the driving screw rod 23. The annular gear ring 24 can rotate inside the rectangular frame plate 13 when driven by an external force, and the corresponding driving screw rod 23 is driven to rotate by the driving gear 25, so that multiple sliding plates 21 can clamp the planetary carrier together.

[0054] Reference Figure 4 As shown, the clamping member 3 is used to contact the planetary carrier; specifically, the clamping member 3 includes an arc plate 30 and a limit key 31, the arc plate 30 is inserted into the end of the sliding plate 21 by bolts, and the inner and outer diameters of the arc plate 30 are provided with several limit keys 31 evenly distributed along its arc surface.

[0055] That is, the sliding plate 21 can drive the arc plate 30 to clamp the outer side of the planetary carrier, and the limit key 31 on the inner diameter of the arc plate 30 can be inserted between the teeth on the outer side of the planetary carrier, increasing the friction between the arc plate 30 and the planetary carrier, and further improving the stability of the arc plate 30.

[0056] And depending on the specifications of the planetary carrier, if there are no teeth on the outside of the planetary carrier, the sliding plate 21 can be used to drive the curved plate 30 to move toward the axis of the circular groove 20, and the planetary carrier can be placed in the circular groove 20 from bottom to top. Then the sliding plate 21 drives the curved plate 30 to move toward the inner diameter of the planetary carrier, so that the outer diameter of the curved plate 30 and the limit key 31 can contact the inner diameter of the planetary carrier, limit the planetary carrier and complete the clamping of the planetary carrier. According to the size specifications of the planetary carrier, the curved plate 30 can be removed from the end of the sliding plate 21, and a new curved plate 30 can be installed on the end of the sliding plate 21 by bolt insertion, so that the inner or outer diameter of the curved plate 30 can clamp the planetary carrier.

[0057] Reference Figure 5 and Figure 6 As shown, the processing box 15 is further provided with a receiving unit 4 for receiving the planetary carrier; specifically, the receiving unit 4 includes a partition plate 40, a receiving plate 41, a receiving screw 42, a stepped groove 43 and a lifting column 44. The partition plate 40 is slidably arranged in the processing box 15 and is interference fit with its inner wall. A receiving plate 41 is rotated on the partition plate 40. When the partition plate 40 is driven by an external force, the receiving plate 41 can drive the receiving plate 41 to move up and down inside the processing box 15. The receiving plate 41 can also rotate on the partition plate 40. The partition plate 40 can drive the receiving plate 41 to move up and down inside the processing box 15. The plate 41 enters the circular groove 20 on the corresponding rectangular frame plate 13 and contacts the bottom of the planetary carrier. Then the sliding plate 21 drives the arc plate 30 to cancel the clamping of the planetary carrier. The receiving plate 41 can drive the planetary carrier to move into the processing box 15, start the heating plate to heat the planetary carrier, and the receiving plate 41 can also drive the planetary carrier to rotate in the processing box 15, so that the planetary carrier can be evenly heated by the heating plate. After the heat treatment is completed, the receiving plate 41 can drive the planetary carrier to move back into the circular groove 20 again, and the arc plate 30 can clamp the planetary carrier again.

[0058] Afterwards, the rectangular frame plate 13 drives the planetary carrier to correspond to another processing box 15, and the receiving plate 41 in the processing box 15 can drive the planetary carrier to move into the processing box 15 to contact the water inside it for quenching. The receiving plate 41 drives the planetary carrier to rotate so that the planetary carrier is in full contact with the water in the processing box 15. After quenching is completed, the receiving plate 41 moves the planetary carrier into the circular groove 20 again, and continues to clamp the planetary carrier through the arc plate 30. Then the rectangular frame plate 13 drives the planetary carrier to no longer correspond to the processing box 15, and the next rectangular frame plate 13 corresponds to the processing box 15 again, and continues to heat treat and quench the planetary carrier according to the above steps.

[0059] The bottom of the processing box 15 is rotatably penetrated by a connecting screw 42 through a threaded connection, and the end of the connecting screw 42 is rotatably penetrated through the partition plate 40 and connected to the connecting plate 41 at the upper end. The connecting screw 42 is driven by external force to rotate and can move up and down in the processing box 15, driving the corresponding partition plate 40 to move up and down in the processing box 15, and the end of the connecting screw 42 can drive the connecting plate 41 at the upper end to rotate. The purpose of the interference fit between the outer side of the partition plate 40 and the inner wall of the processing box 15 is to separate the area inside the bottom processing box 15 from the area at the upper end of the processing box 15, to prevent the temperature heated by the heating plate inside the processing box 15 or the water from contacting the connecting screw 42, causing hot steam or water to flow out through the gap between the connecting screw 42 and the processing box 15.

[0060] Furthermore, after quenching is completed, the water in the processing box 15 can be discharged through the pipeline. After the receiving plate 41 moves the planetary carrier into the circular groove 20 to complete the clamping and finally returns to the processing box 15, clean water can continue to be injected into the processing box 15 through the pipeline.

[0061] In addition, when the receiving screw rod 42 drives the partition plate 40 to move up and down in the processing box 15, the planetary carrier can fully contact the hot air or water in different height areas in the processing box 15, thereby significantly improving the heat treatment and quenching effect of the planetary carrier.

[0062] A stepped groove 43 with a curved cross-section is provided on the receiving plate 41, and several raising columns 44 are provided between the stepped groove 43 and the middle part of the receiving plate 41. The stepped groove 43 is used to adapt to planetary carriers of different sizes to prevent the planetary carriers from deflecting on the receiving plate 41. The raising columns 44 are used to prevent the planetary carriers from directly contacting the inner bottom wall of the receiving plate 41, so that hot air and water can contact the bottom of the planetary carrier.

[0063] Continue to refer to Figure 5 As shown, in order to prevent the hot air or water in the treatment box 15 from leaking out, a partition assembly 5 is provided at the upper end of the treatment box 15; specifically, the partition assembly 5 includes a separation groove 50, a swinging cylinder 51 and a sealing plate 52. The separation groove 50 is opened on the treatment box 15 and is connected to the interior of the treatment box 15, and the upper and lower inner walls of the separation groove 50 are rotated with a swinging cylinder 51. The outer side of the swinging cylinder 51 is provided with a sealing plate 52 which is located in the separation groove 50 and seals the upper end opening of the treatment box 15. When driven by external force, the swinging cylinder 51 can drive the sealing plate 52 to swing in the sealing groove to achieve the effect of sealing or not sealing the upper end opening of the treatment box 15, and when the planetary carrier enters the treatment box 15, the swinging cylinder 51 can also drive the sealing plate 52 to avoid the planetary carrier.

[0064] Reference Figure 7As shown, the pushing component 6 is used to drive the moment frame plate 13 to move to the upper or lower two transverse frame plates 11; specifically, the pushing component 6 includes a through groove 60, a pushing cylinder 61, a pushing plate 62 and a protective plate 63. The through grooves 60 are symmetrically arranged on both sides of the transverse frame plate 11, and the upper and lower through grooves 60 correspond to each other. Two pushing cylinders 61 are symmetrically arranged on the bottom plate 1, and the telescopic end of the pushing cylinder 61 is provided with a pushing plate 62 located between the two transverse frame plates 11, and the pushing plate 62 corresponds to the through grooves 60 adjacent to each other on one side.

[0065] That is, when the planetary frame has completed heat treatment and quenching, the rectangular frame plate 13 moves to correspond to the through-groove 60 on the right. At this time, the pushing cylinder 61 on the right drives the corresponding pushing plate 62 to push the bottom of the rectangular frame plate 13. The rectangular frame plate 13 passes through the through-groove 60 between the two lower transverse frame plates 11 and then passes through the through-groove 60 between the two upper transverse frame plates 11 and enters the two upper transverse frame plates 11. The conveyor belt 12 between the two upper transverse frame plates 11 will drive the rectangular frame plate 13 to move left and right. At this time, the temperature inside the planetary frame in the circular groove 20 will gradually decrease. When the rectangular frame plate 13 approaches the through-groove 60 on the left, the pushing cylinder 61 on the left drives the pushing plate 62 is located between the two upper transverse frame plates 11, so that after the rectangular frame plate 13 moves into the two through grooves 60 on the left, it can be directly supported by the push plate 62 on the left. Then the push plate 62 drives the rectangular frame plate 13 to move between the two lower transverse frame plates 11, and the arc plate 30 cancels the clamping of the planetary carrier, and then the push plate 62 continues to be driven downward by the push cylinder 61. At this time, the rectangular frame is supported by the two lower transverse frame plates 11 and will not move downward anymore. The push plate 62 takes the planetary carrier away, and the implementers can remove the planetary carrier and place a new planetary carrier, and the push plate 62 drives the planetary carrier into the circular groove 20 on the rectangular frame plate 13, and continues to clamp the planetary carrier through the arc plate 30.

[0066] It should be noted that since the push plate 62 cannot fully enter the circular groove 20, after the arc plate 30 completes the clamping, the bottom of the planetary frame may protrude to a part of the outside of the circular groove 20. The push plate 62 moves downward to prevent the planetary frame from protruding from the side of the circular groove 20 and scratching the push plate 62. Then, after the planetary frame completes quenching, the receiving plate 41 is driven by the partition plate 40 to completely enter the circular groove 20. At this time, the arc plate 30 clamps the planetary frame again, and the bottom of the planetary frame will not protrude outside the circular groove 20. When the subsequent rectangular frame plate 13 moves onto the push plate 62, the planetary frame will not collide with the push plate 62, thereby avoiding damage to the planetary frame.

[0067] A plurality of protective plates 63 are installed between the upper and lower corresponding transverse frame plates 11 and are located on both sides of the through slot 60 . The protective plates 63 are used to prevent the rectangular frame plates 13 from tilting and falling when moving upward or downward.

[0068] Example 2: Reference Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, on the basis of Example 1, in order to drive the annular gear ring 24, the swing cylinder 51 and the receiving screw 42 to work, a transmission unit 7 is provided in the rectangular frame plate 13 and the processing box 15; specifically, the transmission unit 7 includes an annular cavity 70, a transmission gear ring 71, a transmission shaft 72, a transmission gear 73, an inner gear ring 1 74, an inner gear ring 2 75, an insertion groove, a structural groove 76, a transmission cylinder 77, a transmission motor 78 and a driving gear 79. The annular cavity 70 is opened in the processing box 15 and corresponds to the receiving screw 42. A transmission gear ring 71 rotates in the annular cavity 70 and is keyed to the outer side of the receiving screw 42. That is, when the transmission gear ring 71 is driven by an external force to rotate in the annular cavity 70, it can drive the receiving screw 42 to rotate by means of the keyway, and because it is keyed, the receiving screw 42 does not interfere with the transmission gear ring 71 when it moves up and down.

[0069] A transmission shaft 72 with one end located in the annular cavity 70 is also rotatably installed in the processing box 15. A transmission gear 73 meshing with the transmission ring gear 71 is sleeved on the outside of the transmission shaft 72. That is, when the transmission shaft 72 is driven by external force, it can drive the transmission ring gear 71 to rotate through the transmission gear 73.

[0070] The other side of the transmission shaft 72 is passed through the swing cylinder 51 and is sleeved with an inner gear ring 1 74, and an inner gear ring 2 75 is provided on the inner diameter of the swing cylinder 51. An insertion groove corresponding to the swing cylinder 51 is provided at the upper end of the processing box 15, and one side of the swing cylinder 51 is located in the insertion groove, and a structural groove 76 corresponding to the insertion groove is provided at the bottom of the rectangular frame plate 13. A transmission cylinder 77 is installed in the rectangular frame plate 13, and a transmission motor 78 is installed at the telescopic end of the transmission cylinder 77. A driving gear 79 meshing with the inner diameter of the annular gear ring 24 is provided on the main shaft of the transmission motor 78, and the driving gear 79 also corresponds to the inner gear ring 1 74 and the inner gear ring 2 75.

[0071] That is, after the rectangular frame 13 corresponds to the processing box 15, the transmission cylinder 77 can drive the corresponding transmission motor 78 to move in the up and down directions. The transmission motor 78 can drive the driving gear 79 at its end to mesh with the annular ring gear 24, the inner ring gear 1 74 and the inner ring gear 2 75 through the insertion groove and the through groove 60 under the drive of the corresponding transmission cylinder 77. When meshing with annular gear ring 24, sliding plate 21 drives clamping member 3 to clamp the planetary carrier. When meshing with inner gear ring 1 74, drive shaft 72 drives swing cylinder 51 to rotate, causing sealing plate 52 to swing open and close the treatment chamber 15. When meshing with inner gear ring 2 75, transmission gear 73 drives transmission gear ring 71 to rotate, which in turn drives receiving plate 41 via receiving screw 42, raising and lowering the receiving plate and rotating it. The transmission cylinder and motor are only briefly engaged during positioning, and after the operation is completed, they are removed with the frame plate. This prevents the drive components from being exposed to the high temperature or water environment of the treatment chamber for a long time, achieving coordinated control of multiple components and ensuring the life of the equipment.
