Description

Technical Field

[0001] The utility model relates to the technical field of axial flow fan blade production, in particular to a cooling and shaping device for axial flow fan blades. Background Art

[0002] Axial flow fan blades typically undergo multiple manufacturing steps, including casting, forging, machining, and heat treatment. During these processes, the fan blades may experience high temperatures, and cooling and shaping are necessary to ensure the final dimensional accuracy and mechanical properties of the fan blades.

[0003] Traditional cooling and shaping systems typically utilize a conveyor system with fans for cooling during transport, making it difficult to ensure uniform cooling. This is because fan cooling is affected by numerous factors, such as blade position, wind direction, wind speed, and the blade's shape and size. These factors can lead to inconsistent cooling rates in different parts of the blade, potentially causing deformation or internal stress. Furthermore, since fan cooling requires continuous operation and often requires high air volumes to ensure effective cooling, this results in high energy consumption. Furthermore, prolonged cooling times can increase production cycle times. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling and shaping device for axial flow fan blades, comprising a frame and a conveying loading platform and a conveying unloading platform respectively installed at the head and tail ends of the frame, a coolant tank is fixed on the inner side of the frame, and a box plate is fixed on the top, and two guide plates located above the coolant tank are fixed, a carrying plate docked with the two guide plates, and a support plate docked with the carrying plate are also fixed on the frame, and a transfer mechanism is installed, a drain pipe and an air intake pipe are connected to one side of the coolant tank, an air duct connected to the air intake pipe is fixed on the inner side of the coolant tank, and a lifting mechanism located above the coolant tank is installed on the box plate.

[0005] Furthermore, two sleeve blocks are fixed on the middle section of the conveying and loading platform, and limit cylinders are installed on the opposite sides of the two sleeve blocks, and the inner sides are slidably connected to limit blocks fixed to the piston rods of the limit cylinders.

[0006] Furthermore, the transfer mechanism is divided into a transverse moving part and a longitudinal moving part. The transverse moving part includes a linear module fixed on the frame. The moving end of the linear module is fixed with a moving plate, and two sets of clamping parts are installed on the moving plate.

[0007] Furthermore, the clamping part includes two double-headed cylinders installed on the movable plate, and a counter-moving plate is fixed on the piston rods at both ends of the double-headed cylinders. Two vertical blocks are fixed on the opposite sides of the two counter-moving plates, and a guide wheel is installed at the bottom of the vertical block, and a side plate is fixed on one side of the two counter-moving plates.

[0008] Furthermore, the longitudinal moving part includes a guide cylinder fixed on the frame, and a push plate is fixed to the piston rod of the guide cylinder.

[0009] Furthermore, the lifting mechanism includes a guide cylinder fixed on the frame and the box plate, the piston rod of the guide cylinder on the box plate is fixed to a orifice plate located above the coolant tank, a ring is fixed at the center of the orifice plate, and the piston rod of another guide cylinder is fixed to the bottom of the supporting plate.

[0010] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0011] The cooling and shaping device of the axial flow fan blade transfers the product to the guide plate through the conveying loading platform. During the conveying process, the product is exposed to the outside and cooled to a certain extent. Then the transfer mechanism transfers the product to the orifice plate in the middle section of the guide plate, the load-bearing plate and the support plate. The lifting mechanism drives the product up and down at a uniform speed through the orifice plate. When the product descends at a uniform speed, the air duct guides the air to cool the product until the product is immersed in the coolant. Then, when it rises evenly, it can be cooled again under the action of the air duct. At the same time, the surface of the product can also be dried, thereby achieving cooling uniformity and reducing energy consumption, while shortening the cooling time and reducing the production cycle.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-3 , a cooling and shaping device for axial flow fan blades in this embodiment includes a frame 1, a conveying loading platform 2 connected to the head end of the frame 1, and a conveying unloading platform 3 connected to the tail end of the frame 1, a coolant tank 7 is fixed on the inner side of the frame 1, and a box plate 10 and a transfer mechanism are fixed on the top of the frame 1, two guide plates 11 and a carrying plate 23 connected to the two guide plates 11, and a support plate 24 connected to the carrying plate 23 and the conveying unloading platform 3 are also fixed on the top of the frame 1, three groups of lifting mechanisms are installed on the box plate 10 and the frame 1, a drain pipe 9 and an air inlet pipe 91 are fixed on the front of the coolant tank 7, an air duct 8 close to the box port is fixed on the inner side of the coolant tank 7, the air duct 8 is connected to the air inlet pipe 91, and the air duct 8 is coiled around the coolant tank 7 in three layers, and the moving end of the transfer mechanism is located between the guide plate 11, the carrying plate 23 and the support plate 24 and moves back and forth.

[0018] Blocks 4 are fixed on both sides of the middle section of the conveyor loading platform 2. Limit cylinders 5 are installed on opposite sides of the two blocks 4. Limit blocks 6, which are fixed to the piston rods of the limit cylinders 5, slide on the inner sides of the blocks 4. When the conveyor loading platform conveys products, the limit cylinders can drive the limit blocks to be ejected. Therefore, the two limit blocks can limit the movement of the products and play a role in limiting the position.

[0019] like Figure 2In the direction shown, in order to realize the product transfer, the transfer mechanism includes a linear module 12 installed on the frame 1, and a moving plate 13 is fixed to the moving end of the linear module 12. Two double-headed cylinders 14 are fixed on the moving plate 13, and the two piston rods of the double-headed cylinders 14 are fixed with a shift plate 15. Two vertical blocks 16 are fixed on the opposite sides of the two relatively distributed shift plates 15, and a high-temperature resistant guide wheel 17 is installed at the bottom of the vertical block 16. The left ends of the two shift plates 15 on the left are fixed with side plates 18, and two arc grooves are provided on both sides of the supporting plate 23. When the product is transferred to the guide plate through the conveyor loading table, the axis of the product is located between the two guide plates, and the double-headed cylinder will drive the moving plates to clamp, and clamp the axis of the product through four guide wheels. Then the linear module drives the moving plate to move, and drives the two double-headed cylinders to move at the same time. When the two sets of double-headed cylinders drive the guide wheels to clamp the product, the distance between the two side blocks is nearly reduced. Therefore, the double-headed cylinder at the head end drives the guide wheels to move the product to the middle of the guide plate, and the double-headed cylinder at the tail end can move the product in the middle of the guide plate to the carrier plate through the guide wheels. At the same time, the two side plates can also push the product on the carrier plate to the support plate, thereby completing the transfer of the product.

[0020] Among them, the lifting mechanism includes two guide cylinders 20 fixed on the frame 1 and a guide cylinder 20 fixed on the box plate 10. The guide cylinder 20 is composed of an H-shaped block, a guide rod and a cylinder. The piston rod of the guide cylinder 20 at the head end is fixed with a hole plate 25 connected to the guide rod. The hole plate 25 is located above the coolant tank 7 and in the middle of the two guide plates 11. Arc grooves are provided on the opposite sides of the middle of the two guide plates 11. A ring 26 is fixed at the center of the hole plate 25, and the axis of the product is adapted to the inner side of the ring 26. Through the above-mentioned transfer mechanism, the product can first be transferred to the arc groove in the middle of the guide plate to match it, and the product also fits into the arc groove. Then the guide cylinder drives the orifice plate to rise and fall until the axis of the product is inserted into the limit of the collar. The transfer mechanism puts the product down, and the guide cylinder drives the orifice plate to descend into the coolant tank until the product is immersed in the coolant tank and then rises, thereby completing the lifting and cooling operation of the product. At the same time, when the product rises, the transfer mechanism will clamp the product and guide the cylinder to retract, so that the product is separated from the collar, so that the product can be transferred to the carrier plate.

[0021] The piston rod of the central guide cylinder 20 is fixedly connected to the carrier plate 23, which is also fixed to the guide rod. After the product is separated from the collar, the guide cylinder drives the carrier plate downward until the transfer mechanism transfers the cooled product to the top of the carrier plate. The carrier plate then lifts and supports the product, pushing it to the appropriate height, allowing the side plates to push the product onto the support plate for placement.

[0022] The piston rod of the tail guide cylinder 20 is fixed with a push plate 21, which is also fixed to the guide rod. When the product is pushed onto the support plate, the transfer mechanism drives the side plate back to the load plate, and the guide cylinder operates, driving the push plate to push the product on the support plate to the conveyor unloading platform to complete the unloading operation.

[0023] The working principle of the above embodiment is:

[0024] The product is conveyed through the conveying loading platform. During the conveying process, the limit cylinder drives the limit block to be ejected, thereby limiting the conveying of the product until the product is conveyed to the guide plate. Then the double-headed cylinder at the head end drives the shift plate to move, and the vertical block drives the guide wheel to clamp the product and push it to the top of the orifice plate. Then the guide cylinder at the head end drives the orifice plate to move up until the sleeve is on the axis of the product to limit the product. Then the guide cylinder at the head end will drive the orifice plate to descend at a uniform speed. During the descent, cold air enters through the air inlet pipe, and then the product is surrounded by air cooling in the coolant tank through the air duct, so as to achieve uniform cooling. After the product is immersed in the coolant for a proper time, the orifice plate rises. At the same time, the product will also be cooled by the air cooling of the air duct in sequence, and the liquid on the product can also be dried until When the product rises to the appropriate height, the linear module drives another set of double-headed cylinders to move above the product, and the double-headed cylinder drives the shift plate to move, so that the guide wheel clamps the product, and then the orifice plate is pushed down a certain distance to separate the product from the ring. At this time, the middle guide cylinder will drive the carrier plate to move down until it is under the next guide plate. At the same time, the linear module can move the product along the guide plate to the top of the carrier plate. The carrier plate rises to support the product, and the guide wheel retreats at the same time, so that the side plate is located between the guide plate and the support plate. The opening and closing of the double-headed cylinder can drive the two side plates to move relative to each other. Therefore, when running through the linear module, the distance between the side plates can push the product to the support plate for placement, and then the tail end guide cylinder drives the push plate to move, and moves the product to the conveyor unloading table to complete the unloading operation.
