Description

Technical Field

[0001] This utility model relates to the field of fan casing stamping technology, specifically to a centrifugal fan casing stamping equipment. Background Technology

[0002] Centrifugal fans are fluid machines that convert mechanical energy into gas pressure energy and use it to transport gas. Centrifugal fans consist of two parts: a casing and a centrifugal impeller. They are characterized by large air volume, stable performance, and smooth rotation. They are widely used in ventilation, dust removal, and cooling in chemical, metallurgical, power, factory, mine, tunnel, cooling tower, vehicle, ship, and building industries. The casing of centrifugal fans is mostly produced by stamping.

[0003] When processing the casing of a centrifugal fan, a large circular through groove needs to be stamped on the surface. Currently, after the stamping equipment completes the stamping of the centrifugal fan casing, the operator still needs to manually remove the casing located below the stamping machine, which makes the processing efficiency of the device low and difficult to meet the usage requirements.

The air extraction pipe is fixedly connected to the inner wall of the rectangular plate at the penetration point. Multiple air extraction holes are opened at the bottom of the rectangular plate, and the air extraction holes communicate with the cavity.

[0008] As a preferred embodiment of the centrifugal fan casing stamping equipment of this utility model, the bottom of the rectangular plate has two embedded grooves, the inner wall of the embedded grooves is fixed with a sealing ring, and the exhaust hole is located between the two sealing rings.

[0009] As a preferred embodiment of the centrifugal fan casing stamping equipment of this utility model, the rectangular plate surface ejection structure includes four springs.

Detailed Implementation

[0024] Please see Figures 1-6A centrifugal fan casing stamping device includes a workbench 1, a stamping table 2 and a support 14 fixed on the top of the workbench 1, a pushing structure installed on the top of the support 14, a rectangular plate 3 and a linkage plate 6 above the stamping table 2, a stamping plate 5 fixed at the bottom of the rectangular plate 3, an adsorption mechanism 4 fixed on the top of the workbench 1, a placement groove 12 and a discharge groove 13 opened on the surface of the stamping table 2, first combination plates 7 fixed on both the left and right sides of the surface of the linkage plate 6, a drive plate 8 hinged to the bottom of the first combination plate 7, two slides 9 fixed on the top of the workbench 1, a second combination plate 10 slidably connected to the surface of the slides 9, a storage shell 11 fixed on the surface of the second combination plate 10, and an ejection structure provided on the surface of the rectangular plate 3.

[0025] The casing to be stamped can be placed into the placement slot 12. The pushing structure can drive the rectangular plate 3 and the stamping plate 5 to move downwards. The stamping plate 5 can pass through the casing and the discharge slot 13 to realize the stamping operation on the surface of the casing. During the downward movement of the rectangular plate 3, the linkage plate 6 will move along with the rectangular plate 3, which will also cause the first combined plate 7 to move, so that the drive plate 8 can rotate and push the second combined plate 10 to move backwards. The storage shell 11 can also move backwards along with the second combined plate 10, thereby avoiding the storage shell 11 from affecting the normal movement of the stamping plate 5. After the stamping is completed, the adsorption mechanism 4 can adsorb the casing onto the surface of the rectangular plate 3. Then the rectangular plate 3 moves upwards, the drive plate 8 continues to rotate and causes the second combined plate 10 to move forwards, so that the storage shell 11 can move to below the rectangular plate 3. At this time, the adsorption of the casing stops. With the help of the ejection structure, the casing can automatically fall into the storage shell 11, thereby realizing the automatic unloading of the stamped casing, eliminating the need for frequent manual material handling and improving the processing efficiency of the device.

[0026] Furthermore, the top pushing structure of the bracket 14 includes a cylinder 15 and a slide rod 16. There are two slide rods 16. The cylinder 15 is fixedly connected to the top of the bracket 14. One end of the cylinder 15 passes through the bracket 14 and is fixedly connected to the top of the linkage plate 6. The surface of the slide rod 16 passes through the bracket 14 and the linkage plate 6. The surface of the slide rod 16 is fixedly connected to the linkage plate 6 and the surface of the rectangular plate 3.

[0027] Cylinder 15 can drive linkage plate 6 to move downward, and linkage plate 6 can drive slide rod 16 to slide together on the surface of bracket 14, so that slide rod 16 can drive rectangular plate 3 to move up and down together.

[0028] Furthermore, the adsorption mechanism 4 includes a vacuum pump 401, which is fixed to the top of the workbench 1. A corrugated pipe 402 is connected to the surface of the vacuum pump 401 through a pipe. A vacuum pipe 403 is connected to the top of the corrugated pipe 402. A cavity 404 is opened inside the rectangular plate 3. The surface of the vacuum pipe 403 penetrates the rectangular plate 3 and is connected to the cavity 404. The vacuum pipe 403 is fixedly connected to the inner wall of the penetration point of the rectangular plate 3. A plurality of exhaust holes 405 are opened at the bottom of the rectangular plate 3 and are connected to the cavity 404.

[0029] When the stamping plate 5 completes the stamping of the housing and the rectangular plate 3 is attached to the surface of the housing, the vacuum pump 401 starts to draw air from the inside of the cavity 404, making the inside of the cavity 404 negative pressure, so that the exhaust port 405 starts to draw air, allowing the housing to be adsorbed onto the surface of the rectangular plate 3. This ensures that the rectangular plate 3 can move the housing upward together, and the bellows 402 can extend and retract to ensure normal gas transmission.

[0030] Furthermore, two embedding grooves are provided at the bottom of the rectangular plate 3, and sealing rings 22 are fixed on the inner wall of the embedding grooves. The exhaust hole 405 is located between the two sealing rings 22.

[0031] When the surface of the sealing ring 22 contacts the surface of the housing, the sealing ring 22 can be compressed and deformed, thereby improving the negative pressure adsorption effect on the housing, making the rectangular plate 3 move the housing and the housing is less likely to fall off.

[0032] Furthermore, the ejection structure on the surface of the rectangular plate 3 includes four springs 18. The springs 18 are fixedly connected to the top of the rectangular plate 3. A top block 21 is fixed to the top of the spring 18. A movable rod 19 is fixed to the bottom of the top block 21. The movable rod 19 slides through the rectangular plate 3. An ejection plate 20 is fixed to the bottom of the movable rod 19. A slot is opened at the bottom of the rectangular plate 3 to accommodate the ejection plate 20. Two ejection frames 17 are fixed to the surface of the bracket 14. The ejection frames 17 are located directly above the top block 21.

[0033] When the rectangular plate 3 moves upward via the cylinder 15, the bottom of the ejector frame 17 can contact the surface of the top block 21. This allows the movable rod 19 to move downward and compresses the spring 18, thereby allowing the ejector plate 20 to detach from the slot and eject the housing adsorbed on the surface of the rectangular plate 3 downward. This prevents the housing from falling downward due to the friction between the stamping plate 5 and the slot of the housing. After the rectangular plate 3 moves downward, the spring 18 returns to its original position, causing the movable rod 19 and the ejector plate 20 to move upward again, returning the ejector plate 20 to the slot. This prevents the ejector plate 20 from affecting the normal stamping process of the housing.

[0034] Furthermore, the ejector plate 20 has a trapezoidal structure design, and the bottom groove shape of the rectangular plate 3 is adapted to the ejector plate 20;

[0035] When the ejector plate 20 moves upward, it can more easily enter the slot by cooperating with the inclined surfaces on both sides of the top and the two inclined surfaces of the slot.

[0036] Furthermore, two support frames 25 are fixed on the top of the workbench 1, and connecting shafts are fixed on both the left and right sides of the surface of the storage shell 11. The surface of the connecting shafts is rotatably connected to movable wheels 24.

[0037] The storage shell 11 can drive the movable wheel 24 to slide on the surface of the support frame 25, which allows the weight of the storage shell 11 to be distributed to the support frame 25, thereby improving the load-bearing capacity of the storage shell 11 and making the storage shell 11 more stable when moving.

[0038] Furthermore, the support frame 25 has grooves on its surface, and the movable wheel 24 is slidably connected to the surface of the grooves;

[0039] The groove can limit the direction of movement of the movable wheel 24, preventing the movable wheel 24 from shifting left or right, thereby ensuring that the storage shell 11 can move in a straight line.

[0040] Furthermore, a receiving drawer 23 is fixed on the top of the workbench 1, and the receiving drawer 23 is located directly below the discharge trough 13;

[0041] The waste material stamped by the stamping plate 5 can fall directly into the receiving drawer 23 through the discharge chute 13, so that the waste material can be automatically collected.

[0042] Furthermore, the storage casing 11 is made of aluminum alloy;

[0043] The aluminum alloy storage casing 11 gives it better load-bearing capacity and is lighter overall.

[0044] Working principle: The housing to be stamped can be placed into the placement slot 12. The cylinder 15, through the cooperation of the slide rod 16 and the linkage plate 6, drives the rectangular plate 3 and the stamping plate 5 to move downward. The stamping plate 5 can penetrate the housing and the discharge slot 13 to realize the stamping operation on the surface of the housing. During the downward movement of the linkage plate 6, the drive plate 8 can rotate and push the second combined plate 10 to move backward, so that the storage shell 11 can also move backward with the second combined plate 10, thereby avoiding the storage shell 11 from affecting the normal movement of the stamping plate 5. After stamping, the vacuum pump 401 is started to cause the housing to adhere to the surface of the rectangular plate 3. Then, the cylinder 15 controls the rectangular plate 3 to move upward, the drive plate 8 to continue rotating and the second combined plate 10 to move forward, so that the storage shell 11 can move to below the rectangular plate 3. At this time, the vacuum pump 401 stops adhering to the housing, and with the downward movement of the movable rod 19, the housing can automatically fall into the storage shell 11, thereby realizing automatic unloading of the stamped housing, so that the manual handling does not need to be frequent and the processing efficiency of the device is improved.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
