Description

Technical Field

[0001] The present invention relates to the technical field of fan impeller processing, and specifically to a manufacturing and processing device for a fan impeller. Background Art

[0002] The fan impeller is the core component of a fan, like the "heart" of the fan, directly determining the performance and efficiency of the fan. It mainly consists of structures such as blades and a hub, and through the principle of aerodynamics, it converts mechanical energy into gas kinetic energy and pressure energy. The shape, angle, and number of the blades are precisely designed to optimize the process of air intake, acceleration, and discharge; the hub is used to fix the blades and transmit power.

[0003] As the core functional component of the fan impeller, the performance of the blades directly determines the working efficiency and service life of the fan. Currently, commonly used blade materials in the industrial field include stainless steel, aluminum alloy, and various high-performance composite materials. During the production and processing process, in order to endow the blades with a specific aerodynamic shape, it is necessary to perform a twist angle treatment on the profile through mechanical equipment so that the blades can efficiently convert the kinetic energy of the airflow during rotation and improve the aerodynamic performance of the fan.

[0004] However, in order to pursue production efficiency, existing processing equipment mostly adopts a fast twisting process driven by an electric motor or hydraulic transmission. Although this method significantly shortens the processing cycle, during the high-speed deformation process, the stress generated inside the blade profile cannot be released in time, resulting in a large accumulation of residual stress. These residual stresses will cause the blades to deform or crack during subsequent service, seriously affecting the operation stability and reliability of the fan, increasing the equipment maintenance cost and the risk of downtime. Therefore, those skilled in the art have proposed a manufacturing and processing device for a fan impeller to solve the above-mentioned technical problems. Summary of the Invention

A ring-shaped support seat is fixedly connected to both sides of the middle of the bottom end of the piston seat.

[0023] Working principle: When processing the blades on the fan impeller, first, the profile fixing mechanism is activated. The operator first pulls up the fixing seat in the first mounting seat through the pull ring seat on it. Then, the operator inserts the raw material of the cut blade profile into the insertion slot on the first mounting seat. After the operator fully inserts the top of the blade profile into the insertion slot, the operator resets the fixed seat that has been moved upward in the first mounting seat. After the fixed seat is reset in the first mounting seat, the limiting ring on the fixed seat limits and fixes its falling position in the first mounting seat. At the same time, when the fixed seat moves downward and resets, it drives the socket at its bottom to move downward synchronously. During the downward movement of the socket, it enters the fitting groove. As the bottom of the socket continues to move downward, the bottom of the socket squeezes the silica gel pad at the bottom of the fitting groove to cause it to deform, thereby increasing the friction force of the insertion slot on the blade profile inside it through the deformed silica gel pad. At the same time, when the socket resets, the striped rubber layer on it also synchronously makes frictional contact with the surface of the blade profile in the insertion slot. Through this multiple friction fixing method, the multiple fixing treatment of the blade profile before processing is completed; Then, the front-end processing mechanism is activated. After the profile fixing mechanism fixes the blade profile to be processed, the main electric cylinder on the base is activated. When the main electric cylinder is activated, the rod on it contracts and descends. When the rod on the main electric cylinder contracts and descends, it drives the connecting seat on it to descend synchronously. When the connecting seat descends, it synchronously drives the first mounting seat, the fixed seat, and the blade profile fixed at its bottom into the interior of the inclined surface annular cover. At this time, the heating wire on the mounting rod is powered on and emits heat. The heat it emits reaches the surface of the blade profile at the bottom of the first mounting seat through the slot on the inclined surface annular cover, and through the coordinated use of the reflection wall in the inclined surface annular cover, the blade profile at the bottom of the first mounting seat is uniformly preheated before plastic processing, so that the material inside the blade profile is heated and softened before plastic processing, thereby completing the front-end pretreatment operation of the blade profile before processing;Then the shaping and processing mechanism is activated. After the front-end processing mechanism finishes the uniform preheating treatment of the blade profile to be processed, the main electric cylinder on the base is activated again. The rod on the main electric cylinder continues to contract and reset. While the rod on the main electric cylinder contracts and resets, it continues to drive the connecting seat, mounting seat 1, fixed seat, and the blade profile after uniform preheating treatment on it into the processing cylinder on the top seat. The blade profile that enters the processing cylinder is inserted between each pair of mounting seat 2 and mounting seat 3. Then the servo electric cylinder on the base is activated, and the rod on the servo electric cylinder slowly extends. While the rod on the servo electric cylinder slowly extends, it drives the piston seat at the bottom of the adjusting cylinder to move upward synchronously. When the piston seat moves upward, it squeezes the liquid in the liquid storage cavity to be discharged and enters the horn cavity in the corresponding position connecting pipe. When the liquid that enters the horn cavity is discharged into the adjusting liquid cavity in mounting seat 2, the liquid flowing in the horn cavity is blocked by the misaligned flow-blocking pieces on the mounting ring pieces at various positions inside it, thereby reducing its flow rate and slowing down the outward movement speed of the shaping seat on mounting seat 2. And the liquid that enters the horn cavity from the liquid storage cavity is synchronously reduced in flow rate due to the influence of the smaller inner diameter pipe orifice at the bottom of the horn cavity. Finally, after the liquid in the horn cavity undergoes multiple flow rate reduction and flow rate slowdown treatments, it enters the adjusting liquid cavity in mounting seat 2. Then, as the volume of the liquid that enters the adjusting liquid cavity slowly increases, it squeezes the connecting seat in the adjusting liquid cavity to move outward. While the connecting seat moves outward, it drives the shaping seat on it to move synchronously towards the position of the mating die seat. While the shaping seat moves, it slowly squeezes and drives the blade profile between mounting seat 2 and mounting seat 3 to approach the position of the mating die seat. With the cooperation of the shaping seat and the mating die seat on mounting seat 3 during the movement of the shaping seat, finally, the shaping and processing of the blade profile is completed through the shaping seat and the mating die seat; When processing blades of different shapes is required, the die seat replacement mechanism is activated. The staff removes the fixing bolt 1 on mounting seat 3, and then slides the mating die seat in the sliding groove 1 in mounting seat 3 upward and pulls it out. While the mating die seat is being pulled out, it synchronously drives the sliding seat in the sliding groove 1 to be separated synchronously. Then the staff takes out the required mating die seat and connects it to the mating die seat. After that, the sliding seat on the connected mating die seat is inserted and reset into the sliding groove 1 on mounting seat 3, and it is fixed with fixing bolt 1. Then the staff removes the fixing bolt 2 on the connecting seat, and then separates the original shaping seat on the connecting seat. After that, the staff inserts the shaping seat to be replaced into the sliding groove 2 on the connecting seat and fixes it with fixing bolt 2, thereby replacing the mating die seat and shaping seat of the original shape, facilitating the subsequent processing of blades of other shapes, and thus completing the replacement processing of the die seat;After the blade is processed, the staff lifts it up through the lifting ring seat on the fixed seat, so that the fixed seat in the mounting seat 1 moves upward. After the fixed seat moves upward, it synchronously drives the fixed seat at its bottom to move upward, so as to release the fixation of the blade after processing in the insertion groove. The staff takes down and collects the blade, and then welds or installs and fixes it to the chassis, thereby completing the manufacturing and processing of the fan impeller.

[0024] The present invention provides a manufacturing and processing device for a fan impeller. It has the following beneficial effects:

[0025] 1. By adding and setting a profile fixing mechanism, the present invention fixes the profile raw material of the fan blade multiple times during the processing. On the one hand, it can ensure the stability of the profile raw material during the processing, thus facilitating the subsequent plastic processing of the profile raw material. On the other hand, it can also avoid the influence of vibration and reaction force on the profile raw material during the subsequent processing, thereby avoiding processing errors caused by material deviation. At the same time, this multiple flexible fixing method not only ensures the fixing strength but also prevents overpressure from damaging the surface, significantly reducing the defective rate and laying a solid foundation for the high-quality and high-efficiency production of fan blades.

[0026] 2. By adding and setting a front-end processing mechanism, the present invention conducts a front-end treatment of uniformly preheating the profile raw material of the fan blade before plastic processing. This treatment method can not only increase the temperature of the profile, fully soften the molecular structure of the material, effectively reduce the material rigidity during plastic processing, facilitate plastic processing while reducing processing energy consumption, but also avoid the thermal stress concentration caused by local temperature difference during the plastic processing, significantly reduce the residual stress inside the blade after forming, improve the material structure stability and anti-fatigue performance, extend the service life of the fan blade, and provide a reliable guarantee for the efficient and safe operation of wind power equipment.

[0027] 3. By adding and setting a shaping and processing mechanism, the present invention significantly improves the processing quality and reliability of the fan impeller blades. When shaping the uniformly preheated blade profiles, this mechanism uses multiple flow reduction and flow blocking technologies to precisely control the moving speed of the shaping seat, achieving slow and progressive shaping. Compared with the traditional rapid processing method, this processing method can enable the atoms inside the material to fully rearrange, effectively eliminate most of the residual stress in the material, reduce the risk of deformation and cracking of the blades during service, and at the same time, slow shaping can make the microstructure of the material more uniform and dense, improving the mechanical properties of the material. Surface defects such as wrinkles and scratches are avoided through a smooth material flow process, reducing the surface roughness of the blades. In addition, this mechanism can also be adapted to special materials such as high-strength alloys and composite materials, ensuring the precise forming of complex aerodynamic shapes through low-stress and high-precision step-by-step shaping, providing a reliable guarantee for the manufacture of high-performance fan impellers.

[0028] 4. By adding and setting a die seat replacement mechanism, when processing the fan impeller blades, this mechanism can replace the corresponding modules according to the processing requirements of the staff. This processing method can not only improve the processing flexibility, enabling the same equipment to be compatible with the production requirements of multiple types of blades, effectively reducing the equipment idle rate, but also break the limitations of the traditional fixed die mode, enabling the equipment to flexibly adapt to the production requirements of blades of various sizes and shapes, significantly improving the flexibility level of the production line, and making it applicable when processing blades of different shapes, with high processing adaptability.

Specific embodiments

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to the attached Figure 1 - attached Figure 2, an embodiment of the present invention provides a manufacturing and processing device for a fan impeller, including a base 1, on the upper part of which there is a top seat 6, and the four corners of the bottom end of the top seat 6 are connected to the corresponding positions of the base 1 through support frames 2; a main electric cylinder 14, which is arranged at the middle rear part of the top end of the base 1, and the top end of the cylinder body of the main electric cylinder 14 penetrates through the top seat 6 and extends upward; a processing cylinder 7, which is arranged on one side of the middle part of the top seat 6 and is used for installing a mold base required for processing and shaping and performing shaping processing on a metal profile raw material;

[0045] Please refer to the attached Figure 3 - attached Figure 4 , a profile fixing mechanism, which is arranged on the top of the top seat 6 and is used for fixing the cut metal profile raw material;

[0046] The profile fixing mechanism includes a first mounting seat 9. A first mounting seat 9 is arranged on one side of the middle front part of the top end of the top seat 6. A plurality of fitting grooves 16 are circumferentially arranged on the bottom end inside the first mounting seat 9. Silicone pads 17 are arranged at the bottom of the inner side of each fitting groove 16. A plurality of insertion grooves 15 are circumferentially arranged near the edge of the bottom end of the first mounting seat 9, and one side inside the insertion groove 15 corresponds to the outside of the fitting groove 16 at the corresponding position.

[0047] When the profile fixing mechanism is started, the staff first pulls up the fixing seat 10 in the first mounting seat 9 through the pull ring seat thereon, and then the staff inserts the cut blade profile raw material into the insertion groove 15 on the first mounting seat 9. After the staff completely inserts the top end of the blade profile into the insertion groove 15, the staff resets the fixed seat 10 that has been moved upward in the first mounting seat 9.

[0048] The profile fixing mechanism further includes a fixing seat 10. The fixing seat 10 is slidably connected inside the first mounting seat 9. A limiting ring 19 is arranged in the middle upper part of the outer wall of the fixing seat 10. A plurality of plug-in seats 20 are circumferentially arranged at the bottom edge of the fixing seat 10. The plug-in seats 20 are matched with the insertion grooves 15. Striped rubber layers 18 are arranged on the outer walls of the plug-in seats 20. Lifting ring seats are arranged on both sides of the middle part of the top end of the fixing seat 10. A connecting seat 11 is fixedly connected to the middle part of one side of the outer wall of the first mounting seat 9, and one side of the middle part of the bottom end of the connecting seat 11 is connected to the top end of the rod body of the main electric cylinder 14.

[0049] After the fixed seat 10 is reset in the first mounting seat 9, the limit ring 19 on the fixed seat 10 limits and fixes its falling position in the first mounting seat 9. At the same time, when the fixed seat 10 moves downward and resets, it drives the socket 20 at its bottom to move downward synchronously. During the downward movement of the socket 20, it enters into the fitting groove 16. As the bottom of the socket 20 continues to move downward, the bottom of the socket 20 presses the silica gel pad 17 at the bottom of the fitting groove 16 to cause it to deform. Thus, the deformed silica gel pad 17 increases the friction force of the insertion groove 15 on the blade profile therein. At the same time, when the socket 20 resets, the striped rubber layer 18 on it also synchronously makes frictional contact with the surface of the blade profile in the insertion groove 15. Through this multiple friction fixing method, the multiple fixing treatment of the blade profile before processing is completed.

[0050] Please refer to the attached Figure 5 - attached Figure 6 , the front-end processing mechanism, which is arranged in the middle front part of the top of the top seat 6 and is used for uniformly heating the raw metal profile before plastic processing;

[0051] The front-end processing mechanism includes an inclined surface annular cover 8. One side of the middle part of the top of the top seat 6 is provided with an inclined surface annular cover 8. A plurality of mounting rods 23 are equidistantly and fixedly connected inside the inclined surface annular cover 8. Heating wires 24 are arranged on the mounting rods 23. A plurality of slots 22 are equidistantly opened on the inner wall of the inclined surface annular cover 8. A reflective wall 21 is arranged on the inner wall of the inclined surface annular cover 8.

[0052] When the front-end processing mechanism is started, after the profile fixing mechanism fixes the required processed blade profile, the main electric cylinder 14 on the base 1 is started. When the main electric cylinder 14 is started, the rod body on it contracts and descends. While the rod body on the main electric cylinder 14 contracts and descends, it drives the connecting seat 11 on it to descend synchronously. While the connecting seat 11 descends, it synchronously drives the first mounting seat 9, the fixed seat 10 on it, and the blade profile fixed at its bottom into the inside of the inclined surface annular cover 8.

[0053] The front-end processing mechanism further includes support rods 13. A plurality of support rods 13 are circumferentially arrayed in the middle front part of the top of the top seat 6. The tops of the support rods 13 are respectively connected to the corresponding positions on the outer wall of the inclined surface annular cover 8. An opening 12 is opened in the middle of the rear side of the inclined surface annular cover 8.

[0054] At this time, the heating wires 24 on the mounting rods 23 are energized and emit heat. The heat emitted by them reaches the surface of the blade profile at the bottom of the first mounting seat 9 through the slots 22 on the inclined surface annular cover 8. Through the coordinated use of the reflective wall 21 in the inclined surface annular cover 8, the blade profile at the bottom of the first mounting seat 9 is uniformly preheated before plastic processing, so that the material inside the blade profile is heated and softened before plastic processing, thus completing the front-end pretreatment operation of the blade profile before processing.

[0055] Please refer to the attached Figure 7 - attached Figure 10 , a die holder replacement mechanism, which is arranged inside the processing cylinder 7 and is used for replacing the die holder according to different processing requirements;

[0056] The die holder replacement mechanism includes multiple groups of second mounting seats 25 and third mounting seats 27. Multiple groups of second mounting seats 25 and third mounting seats 27 are circumferentially arrayed on the inner wall of the processing cylinder 7. An adjustment liquid cavity 38 is opened in the middle of the inner side of each second mounting seat 25. A connecting seat 34 is slidably connected inside each adjustment liquid cavity 38. A sealing ring 36 is arranged on one side of the outer wall of the connecting seat 34. A second sliding groove 33 is opened in the middle of one side of the connecting seat 34. A shaping seat 28 is slidably connected inside each second sliding groove 33. A plurality of second fixing bolts 35 are equidistantly arranged on one side of the connecting seat 34, and the ends of the second fixing bolts 35 enter into the shaping seat 28.

[0057] When the die holder replacement mechanism is started, the operator releases the first fixing bolt 31 on the third mounting seat 27, and then slides the mating die holder 26 in the first sliding groove 30 in the third mounting seat 27 upward and pulls it out. While the mating die holder 26 is being pulled out, the sliding seat 29 in the first sliding groove 30 is synchronously separated. Then the operator takes out the required mating die holder 26, connects it to the mating die holder 26, and then inserts and restores the sliding seat 29 on the connected mating die holder 26 into the first sliding groove 30 on the third mounting seat 27, and fixes it with the first fixing bolt 31.

[0058] The die holder replacement mechanism further includes a first sliding groove 30. A first sliding groove 30 is opened in the middle of each third mounting seat 27. A sliding seat 29 is slidably connected inside the first sliding groove 30. A plurality of extension holes 32 are equidistantly opened on the sliding seat 29. A mating die holder 26 is arranged on one side of the sliding seat 29. A plurality of first fixing bolts 31 are equidistantly arranged in the middle of one side of the third mounting seat 27, and the ends of the first fixing bolts 31 respectively extend into the corresponding extension holes 32.

[0059] Then the operator releases the second fixing bolt 35 on the connecting seat 34, and then separates the original shaping seat 28 on the connecting seat 34. Then the operator inserts the required shaping seat 28 to be replaced into the second sliding groove 33 on the connecting seat 34 and fixes it with the second fixing bolt 35, so as to replace the original-shaped mating die holder 26 and shaping seat 28, which is convenient for the subsequent processing of blades of other shapes, thereby completing the replacement of the die holder.

[0060] Please refer to the attached Figure 11 - attached Figure 13, a shaping processing mechanism, which is arranged on the base 1 and is used for shaping and processing the raw metal profile after the front-end processing mechanism has finished processing.

[0061] The shaping processing mechanism includes an adjusting cylinder 5. The middle part of the bottom end of the processing cylinder 7 is provided with an adjusting cylinder 5. A liquid storage cavity 43 is opened in the middle part of the inner side of the adjusting cylinder 5. A plurality of communicating pipes 37 are evenly arranged at equal distances at the bottom of the inner side of the mounting seat two 25. A horn cavity 42 is opened in each of the communicating pipes 37, and the inside of the horn cavity 42 is communicated with the inside of the liquid storage cavity 43. The inner diameter of one port of the horn cavity 42 close to the liquid storage cavity 43 is smaller than that of the other port.

[0062] When the shaping processing mechanism is started, after the front-end processing mechanism has uniformly preheated the required processed blade profile, the main electric cylinder 14 on the base 1 is started again. The rod body on the main electric cylinder 14 continues to contract and reset. While the rod body on the main electric cylinder 14 contracts and resets, it continues to drive the connecting seat 11, the mounting seat one 9, the fixed seat 10 and the uniformly preheated blade profile thereon into the processing cylinder 7 on the top seat 6.

[0063] The inner diameter of the horn cavity 42 is set to be smaller at the bottom and larger at the top. This setting method is to make the liquid in the liquid storage cavity 43 be discharged under extrusion. The small diameter at the bottom of the horn cavity 42 can reduce its flow rate, thereby reducing the volume of the liquid entering the regulating liquid cavity 38 from the horn cavity 42. At the same time, the affected liquid can also synchronously slow down the pushing and moving speeds of the connecting seat 34 and the shaping seat 28 on the mounting seat two 25, so as to facilitate the slow shaping processing of the raw blade profile.

[0064] The shaping processing mechanism further includes mounting ring pieces 39. A plurality of mounting ring pieces 39 are arranged at equal distances and are staggered on both sides of the inner wall of the horn cavity 42. A staggered flow blocking piece 40 is rotatably connected to each mounting ring piece 39 close to the middle of the horn cavity 42. A one-way limiting seat 41 is fixedly connected to the middle part of one side of the top end of each staggered flow blocking piece 40.

[0065] The blade profiles entering the processing cylinder 7 are inserted between each set of second mounting seats 25 and third mounting seats 27. Then, the servo electric cylinder 3 on the base 1 is started, and the rod body on the servo electric cylinder 3 slowly extends. While the rod body on the servo electric cylinder 3 slowly extends, it drives the piston seat 44 at the bottom of the adjusting cylinder 5 to move upward synchronously. As the piston seat 44 moves upward, it squeezes the liquid in the liquid storage cavity 43 to be discharged and enters the horn cavity 42 in the corresponding position communicating pipe 37. When the liquid entering the horn cavity 42 is discharged into the adjusting liquid cavity 38 in the second mounting seat 25, the liquid flowing in the horn cavity 42 is blocked by the misaligned flow blocking pieces 40 on the mounting ring pieces 39 at various positions inside it, thereby reducing its flow rate and slowing down the outward movement speed of the shaping seat 28 on the second mounting seat 25. Moreover, the flow rate of the liquid entering the horn cavity 42 from the liquid storage cavity 43 is synchronously reduced due to the influence of the smaller inner diameter pipe orifice at the bottom of the horn cavity 42. Finally, after multiple flow reduction and flow buffering treatments, the liquid in the horn cavity 42 enters the adjusting liquid cavity 38 in the second mounting seat 25.

[0066] The misaligned flow blocking pieces 40 in the horn cavity 42, when the liquid in the liquid storage cavity 43 is discharged into the horn cavity 42, are not flipped or rotated under the influence of the one-way limiting seats 41 on them when impacted by the liquid, so that the liquid entering the horn cavity 42 can be blocked and buffered. When the liquid in the adjusting liquid cavity 38 is discharged into the horn cavity 42, the limiting effect of the one-way limiting seats 41 on the misaligned flow blocking pieces 40 disappears. Thus, when the liquid in the adjusting liquid cavity 38 returns to the liquid storage cavity 43 through the horn cavity 42, the misaligned flow blocking pieces 40 are flipped, thereby improving and ensuring the liquid return speed.

[0067] The shaping processing mechanism further includes a piston seat 44. A piston seat 44 is arranged inside the liquid storage cavity 43. The middle front part of the top end of the base 1 is provided with a servo electric cylinder 3, and the top end of the rod body of the servo electric cylinder 3 is connected to the middle part of the bottom end of the piston seat 44. Both sides of the middle part of the bottom end of the piston seat 44 are fixedly connected with annular support seats 4.

[0068] Then, as the liquid volume in the adjusting liquid cavity 38 slowly increases, it squeezes the connecting seat 34 in the adjusting liquid cavity 38 to move outward. While the connecting seat 34 moves outward, it drives the shaping seat 28 on it to move synchronously towards the position of the mating die seat 26. While the shaping seat 28 moves, it slowly squeezes and drives the blade profiles between the second mounting seat 25 and the third mounting seat 27 to approach the position of the mating die seat 26. With the cooperation of the shaping seat 28 and the mating die seat 26 on the third mounting seat 27 during movement, finally, the shaping processing of the blade profiles is completed through the shaping seat 28 and the mating die seat 26.

[0069] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
