Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine impeller production equipment, and in particular to an integrally constructed impeller tire mold. Background Technology

[0002] With the increase in the production output of fan products, the production efficiency of traditional manual assembly and welding for this impeller is limited and cannot meet customer needs. Since the production demand for this type of high-temperature circulating fan for glass tempering furnace is very high, the production cycle and production cost are particularly important. The impeller of this fan has a forward-curved multi-blade structure. The disadvantage of the existing traditional manufacturing method is that manual assembly and spot welding followed by welding of the blades will result in a large difference in the edge distance between the blades, which will affect the later balance accuracy of the impeller. This manufacturing method is inefficient and has high production costs. Therefore, this application proposes an integrally constructed impeller mold. Utility Model Content

[0003] The purpose of this invention is to address the problems of low efficiency, high production cost, and insufficient precision in the manufacturing methods of the prior art, and to propose an integrally structured blade tire mold.

[0004] The technical solution of this utility model is: an integral blade tire mold, including a blade intermediate positioning plate and a tire film device located at the center of the blade intermediate positioning plate. The tire film device includes a blade set at the center of the blade intermediate positioning plate. A tire film for fixing the upper impeller disk is set above the blade. A fan impeller top fixing plate is set on one side of the tire film for fixing the upper impeller disk.

[0005] Optionally, a fan impeller rotating hub is provided on one side of the fixed disk at the top of the fan impeller, and the fan impeller rotating hub is located on one side of the disc on the fixed impeller.

[0006] Optionally, a chassis welding assembly is installed on one side of the rotating hub of the wind turbine impeller, and the chassis welding assembly is located on one side of the top fixing plate of the wind turbine impeller.

[0007] Optionally, the fan impeller hub and the chassis welding assembly are both installed inside the shaft positioner, and the outer wall of the shaft positioner is threaded with multiple upper and lower positioning screws.

[0008] Optionally, an adjustment handle is installed on one side of the blade, and the adjustment handle is located on one side of the positioning disk in the middle of the blade.

[0009] Optionally, the plurality of upper and lower positioning screws are all located on the outer wall of the blade, and the plurality of upper and lower positioning screws are all located on the outer wall of the disc that fixes the upper impeller.

[0010] Compared with existing technologies, this application includes at least one of the following beneficial technical effects: This device, through the coordinated positioning of the blade's intermediate positioning plate, placer, and top fixing plate, can simultaneously place multiple blades into the device and quickly lock them, eliminating the tedious process of adjusting them one by one; and after collective positioning, it can be directly connected to an automatic welding machine for circumferential welding, eliminating the need for manual point-by-point welding. The production time of a single impeller is reduced by 1 / 3 compared to the traditional mode, easily meeting the rapid production needs of large-volume orders, and reducing reliance on manual labor and production costs. There is no need for skilled workers to manually control the blade position; ordinary operators can complete the collective placement and positioning of the blades, reducing the input of highly skilled personnel. By replacing manual welding with automated welding, not only are labor costs reduced, but rework costs caused by human error are also reduced. The shaft positioner and the upper and lower positioning screws form a positioning system, with the edge distance tolerance between blades being less than 0.1mm. The center of gravity deviation of the impeller after assembly is small, and the later balance accuracy is significantly improved. Vibration and noise during fan operation are greatly reduced, and product quality and service life are significantly improved. Attached Figure Description

[0021] Example 1

[0022] like Figures 1 to 3As shown, the integral impeller tire mold proposed in this utility model includes a blade intermediate positioning disk 1 and a membrane device located at the center of the blade intermediate positioning disk 1. The membrane device includes blades 2 set at the center of the blade intermediate positioning disk 1. The blade intermediate positioning disk 1 provides stable support and a central positioning reference for the entire impeller assembly, ensuring that all blades 2 are distributed around the same axis, thus preventing the impeller's center of gravity from shifting at the source. Its surface has reserved blade installation points to guide the blades to quickly and initially align, reducing manual adjustment time. A plate 3 for fixing the upper impeller disk is set above the blades 2. A fan impeller top fixing disk 4 is set on one side of the plate 3 for fixing the upper impeller disk. The two work together to form the positioning structure of the upper part of the impeller. Together with the blade intermediate positioning disk 1, it realizes the positioning of multiple blades 2, ensuring that the spatial position of each blade is accurate and uniform after the blades enter the device collectively, without the need for individual adjustment. A fan impeller rotating hub 5 is set on one side of the fan impeller top fixing disk 4. The fan impeller rotating hub 5 is located on the fixed impeller. On one side of the upper wheel disc's plaque 3, the hub is used to mount the blades 2. A chassis welding assembly 9 is mounted on one side of the fan impeller rotating hub 5. The chassis welding assembly 9 is located on one side of the fan impeller top fixing plate 4. Both the fan impeller rotating hub 5 and the chassis welding assembly 9 are installed inside the shaft locator 8, and the outer wall of the shaft locator 8 is threaded with multiple upper and lower positioning screws 6. The shaft locator 8 serves as the positioning center of the mold, and can adjust the impeller height to adapt to the assembly requirements of impellers of different specifications. The impeller hub 5 and the chassis welding assembly 9 are directly installed inside the shaft positioner 8, achieving coaxial positioning of the hub and the positioning disc. This avoids blade position deviation caused by hub misalignment. The upper and lower positioning screws 6 are distributed along the outer wall of the shaft positioner 8, allowing for flexible adjustment of the impeller width. Simultaneously, they are limited and locked from both sides of the outer wall of the blade 2 and the wheel disc 3 on the fixed impeller, firmly fixing the blade in the set position. This ensures that after multiple blades enter the device together, the edge distance tolerance between the blades is precisely controlled within 0.1mm. Within this design, the precision defects of traditional manual assembly are completely resolved. The chassis welding component 9 is installed in conjunction with the rotating hub 5 of the wind turbine impeller to fix the bottom structure of the impeller and provide stable support for subsequent automated welding. An adjustment handle 7 is installed on one side of the blade 2. The adjustment handle 7 is located on one side of the positioning plate 1 in the middle of the blade. Multiple upper and lower positioning screws 6 are located on the outer wall of the blade 2 and on the outer wall of the plaque 3 that fixes the upper disc of the impeller. The adjustment handle 7 is installed on one side of the blade 2, which can finely adjust the position of a single blade to further optimize the blade spacing accuracy. At the same time, it allows operators to quickly adapt to the positioning needs of blades of different sizes and improves the versatility of the mold.

[0023] The working principle of this embodiment is as follows: According to the height and width specifications of the impeller to be produced, adjust the height of the shaft locator 8, rotate the upper and lower positioning screws 6 to adjust the limit distance, and ensure that the mold is adapted to the current impeller size. Install the fan impeller rotating hub 5 and the chassis welding assembly 9 into the shaft locator 8. The hub is fixed coaxially through the locator. Place multiple blades 2 around the reserved points of the blade middle positioning plate 1. The upper and lower positions of the blades are restricted by the plate 3 fixing the upper disc of the impeller and the fan impeller top fixing plate 4. Then tighten the upper and lower positioning screws 6 to lock the left and right positions of the blades. If fine adjustment is needed, it can be corrected by adjusting the handle 7 to ensure that the edge distance between the blades is accurate. After the mold is positioned, connect the whole device to the automatic welding machine to complete the impeller circumference welding. After welding is completed, loosen the upper and lower positioning screws 6, take out the finished impeller, and after the mold is reset, it can enter the next batch of production.

[0024] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
