Description

Technical Field

[0001] The invention relates to the technical field of spinning equipment, in particular to a spinning machine for processing fan impellers. Background Art

[0002] The fan impeller is the core component of the fan. The quality and shape of the impeller directly determine the performance of the fan. The fan impeller is mainly composed of a hub, a wheel cover, a wheel disc and blades. The hub is the central part of the impeller, which connects the impeller to the fan shaft. The hub is usually made of high-strength metal materials. The wheel cover is located on the outside of the impeller, and the wheel disc is located on the inside of the impeller. Together, they form the frame of the impeller and provide support for the blades. The wheel cover and wheel disc are also usually made of metal materials, and their shapes and sizes match those of the hub and blades. The blades are the key components of the impeller, which directly affect the performance and efficiency of the fan. The blades are usually made of metal materials or composite materials. There are many shapes of blades, and the number of blades varies depending on the type and purpose of the fan. Each component in the fan impeller usually requires a specific curvature and radian, so a spinning machine is needed for processing and production. The spinning machine is a kind of equipment used for metal processing. It mainly rotates the metal blank and applies pressure to gradually deform it under the action of the mold, thereby manufacturing parts of various shapes. After spinning, the internal arrangement of the metal molecules is more compact, and the density will also increase. In addition, when processing some large-sized and high-strength workpieces, the problem of tensile cracking can be avoided; For fan impellers of different sizes and specifications, spinning molds of corresponding specifications are required.

[0014] Compared with the prior art, the present invention provides a spinning machine for processing a fan impeller, which has the following beneficial effects: 1. By setting a stepping rotating component and a supporting component, the supporting component can connect multiple groups of spinning dies of different specifications, and use the internal sliding supporting component to make the spinning dies slide vertically, so that the spinning dies can be close to each other under the extrusion of the hydraulic cylinder and the lower pressing frame, thereby achieving the purpose of extruding the workpiece. In addition, the transmission clutch component inside the supporting component can be rotated by the power of the driving motor and act on the spinning die to achieve the purpose of spinning the workpiece; The stepping rotating component is used in conjunction with the supporting component. Its function is to drive the multiple groups of supporting components arranged on the side to rotate, so that the supporting component equipped with the spinning mold of corresponding specifications can be rotated to the processing station, realizing the purpose of automatic mold replacement, reducing the labor intensity of manual replacement, and improving the production efficiency of spinning work.

[0015] 2. By setting up a sliding support assembly and a transmission clutch assembly, the sliding support assembly can use the internal first bearing seat and the second bearing seat to support the transmission shaft and the linkage shaft in the transmission clutch assembly. The transmission shaft and the linkage shaft are connected to the corresponding spinning mold using the spline shaft on the end face, so that the spinning mold can be horizontally plugged in or removed, and the spline shaft can be used for rotational transmission cooperation. At the same time, the sliding support assembly is also provided with a first spring and a second spring supporting the first bearing seat and the second bearing seat. The first spring can lift the first bearing seat under normal conditions, so that the height of the first bearing seat is higher than the lifting frame, so as to avoid interference between the spinning mold and the lifting frame during rotation, and the second spring can support the second bearing seat, so that the first bearing seat and the second bearing seat remain separated under normal conditions, so that after the spinning work is completed, the spinning mold connected thereto can be automatically separated, which is convenient for the placement and removal of the workpiece.

[0016] 3. By setting the interlocking shaft and the interlocking groove, when the stepping rotating component drives the supporting component to rotate to the processing position, the transmission clutch assembly in the supporting component will move to the position corresponding to the driving motor. At this time, the transmission shaft in the transmission clutch assembly is located above the output shaft of the driving motor. When the spinning mold is pressed and moves downward, the corresponding transmission shaft connected thereto will also move downward. At this time, the interlocking groove opened on the end face of the transmission shaft will engage with the interlocking shaft on the end face of the driving motor and align. At this time, the power of the driving motor will drive the transmission shaft to rotate. When the spinning work is completed, the spinning mold and the transmission shaft are reset, and the interlocking groove will also separate from the interlocking shaft. With such a design, only one driving source needs to be set at the workstation corresponding to the processing position to meet the driving work of the spinning mold, which greatly reduces the cost investment of the driving equipment.

[0017] 4. By setting up a lifting frame and a lower pressing frame, during processing, the stepping rotating component will rotate the supporting component carrying the corresponding spinning mold to the position of the corresponding lifting frame, and then place the workpiece to be processed into the spinning mold. After the spinning mold is subjected to force, it slides downward, so that the punch and mold shaft located below are clamped in the groove at the top of the lifting frame through the bearing ring. At the same time, the hydraulic cylinder drives the lower pressing frame to move downward, so that the lower pressing frame uses the groove at the bottom to clamp with the bearing rings at both ends of the die and the mold shaft, and pushes the die downward to cooperate with the punch to achieve the effect of spinning the workpiece.

The height of the lifting frame 12 corresponds to the driving motor 6, that is, the punch 805 in the spinning mold 8 and the corresponding mold shaft 801, when the bearing ring 802 is clamped in the slot 15 at the top of the lifting frame 12, the mold shaft 801 and the output shaft of the driving motor 6 are in the same horizontal axis, so that it can stably receive the power of the driving motor 6. In addition, the lifting frame 12 also directly bears the pressure of the spinning process, so that the spinning mold 8 can stably rotate and extrude. The lower pressing frame 11 located under the hydraulic cylinder 10, utilizes the connection with the die 804 and the corresponding mold shaft 801 in the spinning mold 8, and clamps the bearing ring 802 through the slot 15 at the bottom, and squeezes the mold shaft 801 together with the die 804 downward, so that the die 804 generates pressure on the workpiece, and utilizes the rotation of the punch 805 to cooperate with each other to achieve the spinning effect.

[0022] A stepping rotating component 5 is provided on the base 1 at a position outside the placement table 4, and a plurality of supporting components 7 are provided on the side of the stepping rotating component 5. A plurality of groups of spinning dies 8 of different sizes are inserted on the side of the plurality of supporting components 7, and the positions of the spinning dies 8 are vertically aligned with the positions of the lifting frame 12 and the lower pressing frame 11. A driving motor 6 is provided on the placement table 4, and a fitting shaft 14 is provided at the output end of the driving motor 6; By setting up the stepping rotating component 5, the supporting component 7 can carry multiple groups of spinning dies 8 of different sizes.

[0023] The supporting component 7 includes a connecting plate 701, a sliding supporting assembly 702 and a transmission clutch assembly 703. The connecting plate 701 is arranged in a ring array on the stepping rotating component 5. The sliding supporting assembly 702 is arranged on the connecting plate 701. The transmission clutch assembly 703 is arranged on the supporting assembly. One end of the transmission clutch assembly 703 is plugged into the spinning mold 8, and the other end is matched with the driving motor 6 through the interlocking shaft 14. In the present invention, a sliding support component 702 and a transmission clutch component 703 are provided. One end of the transmission clutch component 703 can be connected to the spinning mold 8 so that it carries the spinning mold 8, and the other end is connected to the driving motor 6 through the interlocking shaft 14, so that it can drive the spinning mold 8 to rotate. The sliding support component 702 can support and stabilize the position of the transmission clutch component 703, so that the transmission clutch component 703 is in an expanded state under normal conditions, so that when the spinning mold 8 and the transmission clutch component 703 are not working, they can be separated from the lifting frame 12 and the driving motor 6, so that they can be freely moved in or out of the processing station.

[0024] The sliding support assembly 702 includes a support slide 7021 connected to the connecting plate 701, and a first bearing seat 7023 and a second bearing seat 7025 are slidably matched inside the support slide 7021. The bottom of the first bearing seat 7023 is provided with a first spring 7022 connected to the top surface of the connecting plate 701, and the top is provided with a second spring 7024 connected to the bottom of the second bearing seat 7025. The first bearing seat 7023 and the second bearing seat 7025 are rotatably matched with the transmission clutch assembly 703. By setting the first spring 7022 and the second spring 7024, the first spring 7022 directly supports the first bearing seat 7023 and applies an upward push to the first bearing seat 7023, and under normal circumstances, the first bearing seat 7023 is higher than the lifting frame 12 and the driving motor 6, and accordingly, the transmission shaft 7031 inside the first bearing seat 7023 and the mold shaft 801 connected thereto are higher than the engaging shaft 14 and the lifting frame 12, so that they can rotate freely without interference, and the second spring 7024 can support and limit the second bearing seat 7025, so that the second bearing seat 7025 is in a state away from the first bearing seat 7023 under normal circumstances, and accordingly, the internal linkage shaft 7033 moves the die 804 to a position away from the punch 805 through the mold shaft 801 connected thereto, so that the spinning mold 8 is in an expanded state, which is convenient for loading and unloading.

[0025] The transmission clutch assembly 703 includes a transmission shaft 7031 disposed in the first bearing seat 7023, and a linkage shaft 7033 disposed in the second bearing seat 7025, a linkage component 9 is disposed between the linkage shaft 7033 and the transmission shaft 7031, and the end faces of the transmission shaft 7031 and the linkage shaft 7033 are both provided with a spline shaft 7034 plugged into the spinning mold 8, and the end face of the transmission shaft 7031 is provided with an engaging groove 7032 engaged with the engaging shaft 14; By setting the transmission shaft 7031 and the interlocking groove 7032, when the punch 805 is subjected to downward pressure, the bearing ring 802 will be driven to be clamped on the lifting frame 12 through the mold shaft 801, and at the same time, the transmission shaft 7031 will be driven to move downward by utilizing the connection with the spline shaft 7034. When the transmission shaft 7031 moves downward, the interlocking groove 7032 opened on the end face will be used to clamp with the interlocking shaft 14 on the end face of the driving motor 6, so that the driving motor 6 and the transmission shaft 7031 can cooperate in transmission, so that the driving motor 6 can drive the transmission shaft 7031 to rotate through the interlocking shaft 14 and the interlocking groove 7032, and the transmission shaft 7031 drives the punch 805 to rotate through the spline shaft 7034 and the mold shaft 801, so as to achieve the effect of spinning the workpiece, and after the spinning work is completed, the transmission shaft 7031 will drive the interlocking groove 7032 to move upward and reset, so that it is disconnected from the interlocking shaft 14, so as to facilitate the conversion of different spinning molds 8.

[0026] The transmission shaft 7031 is provided with a counterweight 7035 for controlling the docking direction of the engaging groove 7032; By setting a counterweight 7035, the counterweight 7035 is connected to the transmission shaft 7031 and is parallel to the engaging groove 7032. Under normal circumstances, the counterweight 7035 will be in a vertical downward state due to the action of gravity, and will correspondingly drive the transmission shaft 7031 to be in a stable state. The engaging groove 7032 is set in parallel with the counterweight 7035, so that the engaging groove 7032 is also in a vertical downward state. In addition, the driving motor 6 has a built-in position locator, so that the driving motor 6 can drive the engaging shaft 14 to be in a vertical downward state both when starting and stopping, so that after the spinning mold 8 is replaced, the engaging groove 7032 and the engaging shaft 14 can still be stably connected to prevent collision interference problems. Example

[0027] refer to Figure 7 The specific linkage component 9 includes a driving wheel 901 connected to the transmission shaft 7031, a driven wheel 902 connected to the linkage shaft 7033, and a chain 903 connected between the driving wheel 901 and the driven wheel 902. A tensioning wheel 904 is provided in the chain 903. The tensioning wheel 904 and the driven wheel 902 are meshed on the inner side of the chain 903, and the driving wheel 901 is meshed on the outer side of the chain 903. By setting the chain 903 and the tensioning wheel 904, the chain 903 can be used to drive the driving wheel 901 and the driven wheel 902, so that the transmission shaft 7031 and the linkage shaft 7033 can rotate at the same time, so that the concave film and the punch 805 can actively rotate at the same time, avoiding the problem of insufficient friction caused by only rotating the punch 805 to drive the workpiece, improving the working effect during spinning, and achieving the purpose of efficient and stable spinning processing. The tensioning wheel 904 uses its own tension to tighten the chain 903, so that after the positions of the transmission shaft 7031 and the linkage shaft 7033 change, the chain 903 can still maintain a stable transmission effect, and the tensioning wheel 904 can also change the layout of the chain 903, so that the driving wheel 901 is located on the outside of the chain 903, and the driven wheel 902 is located on the inside of the chain 903, so as to achieve the purpose of reverse movement of the driving wheel 901 and the driven wheel 902, so that the concave mold 804 and the punch 805 can stably push the workpiece when rotating.

[0028] A connecting frame 905 is provided on the side of the tension wheel 904, and sliding rods 906 are slidably matched at both ends of the connecting frame 905. A fourth spring 907 is sleeved on the outer side of the sliding rod 906. One end of the fourth spring 907 is connected to the bottom surface of the connecting frame 905, and the other end is connected to the top surface of the connecting plate 701; By setting the sliding rod 906 and the fourth spring 907, the sliding rod 906 can utilize the vertical sliding cooperation with the connecting frame 905 to stabilize the position of the tensioning wheel 904 connected to the connecting frame 905, so that the tensioning wheel 904 can be forced downward under the pulling force of the fourth spring 907, so that it can maintain a tensioned state and automatically adapt to the position changes of the driving wheel 901 and the driven wheel 902 to achieve a stable tensioning effect. What needs to be further understood is that the pulling force of the fourth spring 907 is less than the elastic force of the first spring 7022 and the second spring 7024, that is, only when the distance between the driving wheel 901 and the driven wheel 902 is reduced, causing the chain 903 to relax, the fourth spring 907 can pull the tensioning wheel 904 downward through the connecting frame 905, otherwise the elastic force of the fourth spring 907 cannot actively affect the position of the driving wheel 901 and the driven wheel 902. Example

[0029] refer to Fig. 9 , 10 The specific spinning mold 8 includes two mold shafts 801, both ends of the two mold shafts 801 are provided with spline holes 803 plugged with the spline shaft 7034, and the two mold shafts 801 are respectively provided with a concave mold 804 and a convex mold 805, and both ends of the mold shaft 801 are provided with bearing rings 802, and the bearing rings 802 are fitted with the lifting frame 12 and the card slots 15 in the lower pressing frame 11; By providing the bearing ring 802 and the spline hole 803, the bearing ring 802 is provided at both ends of the mold shaft 801. When working, the outer ring fits with the lifting frame 12 and the lower pressing frame 11, and the inner ring is connected with the mold shaft 801, so that the mold shaft 801 can rotate stably. In this way, there is no need to provide the bearing ring 802 in the lifting frame 12 and the lower pressing frame 11, which greatly simplifies the process of replacing the spinning mold 8 and improves the efficiency of replacement. The spline holes 803 at both ends of the mold shaft 801 can be plugged into the spline shaft 7034. On the one hand, the mold shaft 801 can be connected to the corresponding transmission shaft 7031 and the linkage shaft 7033. On the other hand, the spline connection method is used to facilitate taking and placing while ensuring a stable rotation transmission effect.

[0030] A clamping member 704 is provided in the spline shaft 7034, a groove 806 which is matched and connected with the clamping member 704 is provided in the spline hole 803, the clamping member 704 includes a placement groove 7041 provided in the spline shaft 7034, a third spring 7042 is provided in the placement groove 7041, a steel ball 7043 is provided on the end surface of the third spring 7042, and the steel ball 7043 is clamped with the groove 806 in the spline hole 803; By providing the third spring 7042 and the steel ball 7043, after the spline hole 803 is plugged into the spline shaft 7034, the third spring 7042 in the spline shaft 7034 will use its own elastic force to push the steel ball 7043, so that the steel ball 7043 is engaged with the groove 806 in the spline hole 803, so that the spline hole 803 is connected to the spline shaft 7034, preventing the spline hole 803 from being separated from the spline shaft 7034 without external force, thereby ensuring stability when switching the spinning mold 8.

[0032] The bottom plate 501 is provided with support rollers 506 that are in contact with the bottom surface of the support component 7, and the support rollers 506 are arranged in a circular array along the center of the bottom plate 501; By setting the support roller 506, the support roller 506 can carry the support component 7, so that the support component 7 can stably rotate on the support roller 506, and the support roller 506 uses its own rotation to reduce the friction force when the support component 7 rotates, so that the rotation of the support component 7 is smoother and the problem of metal wear is reduced. In addition, the support roller 506 can be further replaced with an outer nylon material or a harder rubber material, so that it can reduce noise while carrying the load.

[0033] Working principle: When spinning is required, the stepper motor 504 drives the rotating ring 503 to rotate through the gear 505 and the inner gear ring 507, and the rotating ring 503 drives the supporting component 7 carrying the corresponding spinning mold 8 to rotate to the position of the corresponding lifting frame 12, and then the workpiece is placed on the punch 805. The punch 805 drives the mold shaft 801 to move downward under the pressure of the workpiece. The mold shaft 801 is clamped on the lifting frame 12 by the bearing ring 802, and at the same time drives the transmission shaft 7031 connected thereto to move downward, so that the interlocking groove 7032 on the end face of the transmission shaft 7031 is connected to the interlocking shaft 14; The hydraulic cylinder 10 drives the lower pressing frame 11 to move downward, so that the lower pressing frame 11 drives the mold shaft 801 provided with the concave mold 804 to move downward through the bearing ring 802, so that the concave mold 804 fits on the workpiece and continuously applies pressure to the workpiece, and then the driving motor 6 drives the transmission shaft 7031 to rotate through the interlocking shaft 14 and the interlocking groove 7032, and the transmission shaft 7031 drives the mold shaft 801 to rotate by using the spline shaft 7034 and the spline hole 803, and the mold shaft 801 drives the punch 805 to rotate, and the punch 805 spins the workpiece by using the rotation and the pressure of the concave mold 804; When the transmission shaft 7031 rotates, it drives the driving wheel 901 connected thereto to rotate, and the driving wheel 901 drives the driven wheel 902 to rotate by means of the chain 903, and the driven wheel 902 rotates by means of the linkage shaft 7033 and the mold shaft 801 connected thereto, and the mold shaft 801 drives the concave die 804 to spin the workpiece while extruding it, and when the distance between the driving wheel 901 and the driven wheel 902 changes, the fourth spring 907 drives the tensioning wheel 904 to move by means of the connecting frame 905, so that the tensioning wheel 904 tightens the chain 903; When the spinning work is completed, the hydraulic cylinder 10 drives the lower pressure frame 11 to move upward and reset, and the first spring 7022 and the second spring 7024 drive the first bearing seat 7023 and the second bearing seat 7025 to move upward and reset, so that the corresponding transmission shaft 7031 moves upward and separates it from the engaging shaft 14, and at the same time drives the mold shaft 801 to separate from the lifting frame 12.
