Abstract
Description
Technical Field
[0001] This utility model belongs to the field of centrifugal impeller manufacturing technology, specifically, it relates to a forward-inclined centrifugal impeller shaping device. Background Technology
[0002] A centrifugal impeller is a type of impeller that draws air in axially and discharges air radially, using centrifugal force (depending on the rotational speed and outer diameter) to increase the pressure of the air.
[0003] Centrifugal fan impellers can be classified into forward-curved impellers, radial impellers, and backward-curved impellers according to their blade angles. A forward-curved impeller is one whose impeller outlet angle is greater than 90 degrees. In layman's terms, a forward-curved impeller is one in which the angle between the outer extension of the blade and the tangent in the direction of rotation of the blade at that point is obtuse when viewed from the radial section of the impeller.
[0004] During the production of the fan impeller, the blades need to be riveted and fixed with the splice plate. However, the existing riveting process cannot properly fix the impeller, making the riveting process quite troublesome. Utility Model Content
[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0006] To address the problem mentioned in the background art that during the production of fan impellers, the blades need to be riveted and fixed with the connecting plates, but the existing riveting process cannot effectively fix the impeller, resulting in a cumbersome riveting process, this utility model adopts the following technical solution.
[0007] A forward-inclined centrifugal impeller shaping device includes a worktable, a first drive motor detachably connected to the upper center of the worktable, a placement platform detachably connected to the rotating end of the first drive motor, a fixing component installed on the upper end of the worktable to fix the impeller on the placement platform, and a riveting component installed on one side of the upper end of the worktable to rivet the impeller.
[0008] Preferably, the fixing assembly includes a fixed pressure plate, an adjusting plate, a first sliding rod, a first electric telescopic rod, and a limiting block. The first sliding rod is fixedly connected to one side of the upper end of the worktable. The adjusting plate is slidably connected to the outer wall of the first sliding rod. The fixed pressure plate is rotatably connected to the bottom of the adjusting plate. The limiting block is detachably connected to the top of the first sliding rod. The first electric telescopic rod is detachably connected to one side of the upper end of the worktable. The telescopic end of the first electric telescopic rod is detachably connected to the bottom of the adjusting plate. The telescopic extension of the first electric telescopic rod causes the adjusting plate to move upward or downward on the outer wall of the first sliding rod.
[0009] Preferably, the placement platform is provided with multiple limiting slots, and the impeller is sleeved on the outer wall of the placement platform, with each blade inserted into the inside of the limiting slot.
[0010] Preferably, the riveting assembly includes a connecting seat, a riveting ball, a second electric telescopic rod, a mounting block, a second drive motor, a second sliding rod, and a bidirectional screw. A riveting box is detachably connected to one side of the upper end of the worktable. The second sliding rod is fixedly connected to both sides inside the riveting box. Mounting blocks are slidably connected to the two sides of the second sliding rod. The outer walls of the two mounting blocks are detachably connected to the second electric telescopic rod. The telescopic end of the second electric telescopic rod is detachably connected to a connecting seat. A riveting ball is rotatably connected inside the connecting seat. The upper end of the riveting box is detachably connected to the second drive motor. The rotating end of the second drive motor is inserted into the riveting box and detachably connected to the bidirectional screw. The bidirectional screw is threadedly connected to the two mounting blocks. The rotation of the second drive motor drives the bidirectional screw to rotate, causing the two mounting blocks to move simultaneously towards or in opposite directions.
[0011] Preferably, a feeding assembly is installed on the outer wall of the first sliding rod, and the feeding assembly moves upward and downward along with the adjusting plate.
[0012] Preferably, the feeding assembly includes a feeding ring, a connecting plate, a sliding ring, an adjusting screw, and a rotating cap. The outer wall of the first sliding rod is slidably connected to the sliding ring, the outer wall of the sliding ring is fixedly connected to the connecting plate, the end of the connecting plate is fixedly connected to the feeding ring, the feeding ring is sleeved on the outside of the placement platform, the bottom of the adjusting plate is rotatably connected to the adjusting screw, the adjusting screw is threadedly connected to the connecting plate, and the bottom of the adjusting screw is fixedly connected to the rotating cap.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. By extending or retracting the first electric telescopic rod in the fixed assembly, the adjusting plate moves upward or downward on the outer wall of the first sliding rod, thereby enabling the fixed pressure plate to move upward or downward. The downward movement of the fixed pressure plate fixes the impeller, and the blades inserted into the limiting slot can assist in limiting the impeller.
[0015] 2. The second drive motor rotates to drive the bidirectional screw, which causes the two mounting blocks on both sides to move in opposite directions at the same time. This allows them to be locked onto both sides of the impeller. The riveting balls on both sides contact the upper and lower ends of the impeller, thus enabling riveting when the impeller rotates, thereby achieving the purpose of automatic riveting.
[0016] 3. The adjusting screw in the feeding assembly allows the feeding ring and the adjusting plate to move up and down simultaneously. This allows the feeding ring to move upwards when the adjusting plate moves upwards after the riveting is completed, thus removing the impeller from the placement table. By rotating the rotating cap, the adjusting screw can be rotated to adjust the distance between the feeding ring and the adjusting plate, preventing the distance from being too large or too small, which could affect the fixing of the impeller or the feeding of the impeller.

The impeller is placed above the placement platform 102, and the fixing plate 200 moves downward to fix the impeller. In this embodiment, the rotation of the first drive motor 101 drives the placement platform 102 to rotate, thereby enabling the impeller to rotate, making riveting more convenient. The fixing plate 200 can fix the impeller during riveting.
[0030] like Figure 2 As shown, this is a schematic diagram of the fixed component structure in this embodiment. A first sliding rod 202 is fixedly connected to one side of the upper end of the workbench 100. An adjusting plate 201 is slidably connected to the outer wall of the first sliding rod 202. The fixed pressure plate 200 is rotatably connected to the bottom of the adjusting plate 201. A limit block 204 is detachably connected to the top of the first sliding rod 202. A first electric telescopic rod 203 is detachably connected to one side of the upper end of the workbench 100. The telescopic end of the first electric telescopic rod 203 is detachably connected to the bottom of the adjusting plate 201. In this embodiment, the adjusting plate 201 moves upward or downward on the outer wall of the first sliding rod 202 by the extension and retraction of the first electric telescopic rod 203, thereby enabling the fixed pressure plate 200 to move upward or downward. The downward movement of the fixed pressure plate 200 fixes the impeller.
[0031] It is worth noting that the aforementioned fixed pressure plate 200, adjusting plate 201, first sliding rod 202, first electric telescopic rod 203, and limiting block 204 are the fixing components in this embodiment. The fixing components include, but are not limited to, the fixed pressure plate 200, adjusting plate 201, first sliding rod 202, first electric telescopic rod 203, and limiting block 204. Any component that can fix the impeller can be used in this embodiment.
[0032] like Figure 2 As shown, the placement platform 102 is provided with multiple limiting slots 103. The impeller is sleeved on the outer wall of the placement platform 102, and each blade is inserted into the inside of the limiting slot 103. In this embodiment, the blades can be inserted into the inside of the limiting slot 103 to help limit the impeller.
[0033] like Figure 3 As shown, this is a schematic diagram of the riveting assembly structure in this embodiment. A riveting box 303 is detachably connected to one side of the upper end of the workbench 100. Second sliding rods 304 are fixedly connected to both sides inside the riveting box 303.

A connecting seat 301 is detachably connected to the telescopic end of the second electric telescopic rod 302. A riveting ball 300 is rotatably connected inside the connecting seat 301. The upper end of the riveting box 303 is detachably connected to... A second drive motor 306 is connected, and the rotating end of the second drive motor 306 is inserted into the riveting box 303 and is detachably connected to a bidirectional screw 307. The bidirectional screw 307 is threadedly connected to the mounting blocks 305 on both sides. In this embodiment, the rotation of the second drive motor 306 drives the bidirectional screw 307 to rotate, thereby enabling the mounting blocks 305 on both sides to move simultaneously towards or away from each other, and thus be able to be locked on both sides of the impeller. The riveting balls 300 on both sides contact the upper and lower ends of the impeller, so that riveting can be performed when the impeller rotates, thereby achieving the purpose of automatic riveting.
[0034] It is worth noting that the aforementioned connecting seat 301, riveting ball 300, second electric telescopic rod 302, mounting block 305, second drive motor 306, second sliding rod 304, and bidirectional screw 307 are the riveting components in this embodiment.

A feeding ring 400 is fixedly connected to the end of the connecting plate 401. The feeding ring 400 is sleeved on the outside of the placement platform 102. An adjusting screw 403 is rotatably connected to the bottom of the adjusting plate 201. The adjusting screw 403 is threadedly connected to the connecting plate 401. A rotating cap 404 is fixedly connected to the bottom of the adjusting screw 403. In this embodiment, by adjusting the screw 403, the feeding ring 400 and the adjusting plate 201 can move up and down simultaneously. Thus, when the adjusting plate 201 moves upward after the riveting is completed, the feeding ring 400 moves upward at the same time, thereby removing the impeller from the placement table 102. By rotating the rotating cap 404, the adjusting screw 403 can be rotated, thereby adjusting the distance between the feeding ring 400 and the adjusting plate 201, avoiding the distance being too large or too small, which would affect the fixing of the impeller or the feeding of the impeller.
[0036] It is worth noting that the above-mentioned feeding ring 400, connecting plate 401, sliding ring 402, adjusting screw 403 and rotating cap 404 are feeding components in this embodiment.
