Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically a conveying device for processing forgings for new energy vehicles. Background Technology

[0002] In the forging process of transmission components (such as bearings and gears) in new energy vehicles, in order to achieve a balance between lightweight materials and high strength, it is necessary to rapidly cool the high-temperature forgings. Existing technologies typically employ a cooling solution with a conveyor device equipped with a top cooling fan, but this method has the following significant drawbacks:

[0003] Insufficient airflow coverage: The cooling fan blows air vertically only from the top, while the forging is fixed in position on the conveyor belt and moves at a relatively fast speed, which causes the airflow to fail to fully contact the surface of the forging (especially the sides and bottom), creating localized cooling blind spots;

[0004] Low heat exchange efficiency: Since the heat inside the forging needs to be dissipated through surface conduction, the existing cooling method is difficult to achieve uniform heat exchange due to uneven airflow distribution. The forging still needs additional natural cooling after the heat is concentrated, which seriously restricts the production line cycle time.

[0005] Lack of dynamic cooling: The continuous movement of the conveying device and the static cooling fan create a contradiction. The high-speed moving forging cannot obtain continuous and effective cooling, while the fixed cooling fan cannot adapt to the differentiated cooling needs of forgings of different sizes.

[0006] Based on this, the present invention designs a conveying device for processing forgings for new energy vehicles to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a conveying device for processing forgings for new energy vehicles, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for processing forgings for new energy vehicles, comprising a chain conveyor belt, a cooling fan disposed above the chain conveyor belt, a tilting frame rotatably connected to the top of the chain conveyor belt, a feed hopper disposed above the tilting frame, and telescopic plates slidably connected to both ends of the bottom of the tilting frame; and a drive mechanism for controlling the rotation of the tilting frame is provided on the chain conveyor belt, comprising:

[0009] Transmission assembly one is fixed to the outer wall of the front end of the chain conveyor belt;

[0010] Two turntables are rotatably connected by a transmission assembly. A swing arm is rotatably connected at the front end of the turntables, which is not at the center of rotation. The top of the swing arm is rotatably connected to one side wall of the flipping frame.

[0011] The front end of the flip frame is slidably connected to a material distribution plate, and the material distribution plate is provided with a layered feeding mechanism. The layered feeding mechanism is used to drive the material distribution plate to slide into the flip frame and control the telescopic plate to retract into the flip frame.

[0012] As a further embodiment of the present invention, the layered feeding mechanism includes two telescopic plates, which are slidably disposed inside the left and right sides of the dividing plate. A convex shaft is fixedly connected to the rear top of the telescopic plate. A horizontally inclined limiting frame is fixedly connected to the top of the flipping frame. A connecting block for sliding connection with the limiting frame is fixedly connected to the top of the convex shaft. Connecting shafts are fixedly connected to both sides of the bottom end of the dividing plate. A connecting frame is fixedly connected to the top of the telescopic plate, and a lever for contacting the connecting shaft is fixedly connected to the top of the connecting frame.

[0013] As a further embodiment of the present invention, a fixed plate is fixedly connected to the top of the chain conveyor belt, a rotary shaft is fixedly connected to the bottom of the flipping frame, the top of the fixed plate is rotatably connected to the rotary shaft, a second motor is fixedly connected to the front end of the fixed plate, the output shaft of the second motor is concentric with the rotary shaft, a second transmission assembly is rotatably connected to the output shaft of the second motor, a lead screw is rotatably connected to the top of the second transmission assembly, and the lead screw is threadedly connected to the bottom of the material distribution plate.

[0014] As a further embodiment of the present invention, a reset spring for resetting the telescopic plate is fixedly connected to the bottom end of the flip frame.

[0015] As a further embodiment of the present invention, a motor is fixedly connected to the front end of the transmission assembly, and the output end of the motor passes through the transmission assembly and is rotatably connected to the turntable.

[0016] As a further embodiment of the present invention, the flip frame, the material distribution plate, the first telescopic plate and the second telescopic plate are all made of a grating material with strong heat resistance.

[0017] As a further embodiment of the present invention, the front end of the flipping frame is provided with a slot for sliding connection with the material distribution plate, and a heat-conducting plate is fixedly connected inside the slot.

[0018] As a further aspect of the present invention, the cooling fan is internally connected to a plurality of fan blade groups that are equidistantly distributed.

[0019] As a further embodiment of the present invention, the feed hopper is inclined above the flipping frame, and the top of the feed hopper is connected to the output end of the forging equipment.

[0020] As a further embodiment of the present invention, side baffles are fixedly connected to both sides of the top of the chain conveyor belt.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention employs a drive mechanism, in which the transmission group drives two turntables to rotate counterclockwise. Under the action of the swing arms on both sides, the flipping frame rotates around the center of rotation. The purpose is to allow the parts that enter the flipping frame through the feed hopper to roll back and forth inside the flipping frame as it flips. This not only prolongs the heat dissipation time between the parts and the cooling fan, but also allows the parts to continuously change their contact position with the bottom of the flipping frame as they roll inside. This is beneficial for heat dissipation and reduces the risk of localized overheating of the flipping frame due to prolonged contact between the parts and the same position.

[0023] The layered feeding mechanism drives the distribution plate to move into the inside of the tilting frame, so that the parts that enter the tilting frame from the feed hopper fall on the distribution plate. At the same time, the layered feeding mechanism drives the telescopic plate to retract into the inside of the tilting frame, so that the openings on both sides of the tilting frame open. As the tilting frame tilts, the parts that have completed heat dissipation fall from the openings on both sides into the chain conveyor belt under the action of gravity. After being transported by the chain conveyor belt, the layered feeding mechanism realizes the layered processing of the parts. That is, when the distribution plate slides into the inside of the tilting frame, the slots on both sides of the distribution plate are horizontally stretched to close the internal space of the tilting frame to intercept uncooled parts. At the same time, the telescopic plate at the bottom of the tilting frame retracts, so that the bottom opening of the tilting frame opens to transport cooled parts. Attached Figure Description

[0035] Please see Figure 1-9 This invention provides a technical solution: a conveying device for processing forgings for new energy vehicles, including a chain conveyor belt 3, a cooling fan 1 disposed above the chain conveyor belt 3, a tilting frame 4 rotatably connected to the top of the chain conveyor belt 3, a feeding hopper 2 disposed above the tilting frame 4, the feeding hopper 2 being inclinedly disposed above the tilting frame 4, the top of the feeding hopper 2 being connected to the output end of the forging equipment, the parts forged by the forging equipment being transported to the interior of the tilting frame 4 via the feeding hopper 2, the cooling fan 1 blowing air from the top to cool the parts inside the tilting frame 4, and telescopic plates 12 being slidably connected to both ends of the bottom of the tilting frame 4, and a drive mechanism for controlling the rotation of the tilting frame 4 being provided on the chain conveyor belt 3, including:

[0036] Transmission assembly 8 is fixed to the outer wall of the front end of the chain conveyor belt 3;

[0037] Two turntables 9 are rotatably connected via a transmission assembly 8. A swing arm 10 is rotatably connected to the front end of each turntable 9 at a point other than the center of rotation. The top end of the swing arm 10 is rotatably connected to one side wall of the flipping frame 4. (See [reference]) Figures 2-3 When the transmission assembly 8 drives the two turntables 9 to rotate counterclockwise, the tilting frame 4 rotates around the center of rotation under the action of the swing rods 10 on both sides. Figure 3 The rotation shown is intended to allow the parts that enter the inside of the flip frame 4 through the feed hopper 2 to roll back and forth inside the flip frame 4 as it flips. This not only prolongs the heat dissipation time between the parts and the cooling fan 1, but also allows the parts to continuously change their contact position with the bottom of the flip frame 4 as they roll inside the flip frame 4. This is beneficial for the heat dissipation of the parts and reduces the risk of the flip frame 4 overheating due to prolonged contact between the parts and the same position.

[0038] The front end of the flipping frame 4 is slidably connected to a material distribution plate 5. The material distribution plate 5 is provided with a layered feeding mechanism. The layered feeding mechanism is used to drive the material distribution plate 5 to slide into the flipping frame 4 and control the telescopic plate 12 to retract into the flipping frame 4.

[0039] After the flipping frame 4 flips to allow the internal parts to dissipate heat sufficiently, the layered feeding mechanism drives the distribution plate 5 to move into the inside of the flipping frame 4, so that the parts that subsequently enter the inside of the flipping frame 4 from the feed hopper 2 fall above the distribution plate 5. At the same time, the layered feeding mechanism drives the telescopic plate 12 to retract into the inside of the flipping frame 4, so that the two sides of the flipping frame 4 open up. Then, as the flipping frame 4 flips, the parts that have completed heat dissipation fall from the two side openings into the chain conveyor belt 3 under the action of gravity. After being transported by the chain conveyor belt 3, the layered feeding mechanism realizes the layered processing of the parts.

[0040] As a further embodiment of the present invention, the layered feeding mechanism includes two telescopic plates 20, which are slidably disposed inside the left and right sides of the dividing plate 5. A convex shaft 21 is fixedly connected to the rear side of the top of the telescopic plate 20. A horizontally inclined limiting frame 23 is fixedly connected to the top of the flipping frame 4. A connecting block 22 for sliding connection with the limiting frame 23 is fixedly connected to the top of the convex shaft 21. A connecting shaft 24 is fixedly connected to both sides of the bottom end of the dividing plate 5. A connecting frame 13 is fixedly connected to the top of the telescopic plate 12. A lever 14 for contacting the connecting shaft 24 is fixedly connected to the top of the connecting frame 13. A reset spring 11 for resetting the telescopic plate 12 is fixedly connected to the bottom end of the flipping frame 4.

[0041] See Figures 4-6 After the internal parts of the flip frame 4 have cooled down, the material distribution plate 5 is pushed to slide into the flip frame 4. At the same time, the connecting block 22 slides obliquely along the limiting frame 23, causing the telescopic plate 20 to slide backward by a distance L1 with the material distribution plate 5. At the same time, the convex shaft 21 will stretch the telescopic plate 20 horizontally by a distance L2 (see...). Figures 7-8 Furthermore, the connecting shaft 24 at the bottom of the material distribution plate 5 slides backward with the material distribution plate 5, and the connecting shaft 24 pushes the lever 14 to cause the telescopic plate 12 to stretch the return spring 11 by a horizontal sliding distance L3 (see...). Figure 9 This causes the bottom two sides of the flip frame 4 to open up;

[0042] In summary, when the material distribution plate 5 slides into the interior of the flipping frame 4, the slots 15 on both sides of the material distribution plate 5 are horizontally stretched to close the interior space of the flipping frame 4 to intercept uncooled parts. At the same time, the telescopic plate 12 at the bottom of the flipping frame 4 retracts, causing the bottom of the flipping frame 4 to open and open for conveying cooled parts. After the parts on the material distribution plate 5 have cooled down as the flipping frame 4 flips, the material distribution plate 5 is stretched back to its original position. During the reset process of the material distribution plate 5, the slots 15 gradually close, and the lever 14 gradually resets under the elastic force of the reset spring 11 after disengaging from the connecting shaft 24. During this process, the flipping frame 4 flips continuously, so the cooled parts on the slots 15 can fall into the bottom of the flipping frame 4 through the gradually enlarging opening of the slots 15 as they retract, and then fall into the chain conveyor belt 3 through the gradually decreasing opening of the telescopic plates 12 on both sides of the bottom of the flipping frame 4, thus realizing the conveying of cooled parts on the material distribution plate 5.

[0043] As a further embodiment of the present invention, a fixed plate 6 is fixedly connected to the top of the chain conveyor belt 3, a rotary shaft 16 is fixedly connected to the bottom of the flipping frame 4, the top of the fixed plate 6 is rotatably connected to the rotary shaft 16, a second motor 17 is fixedly connected to the front end of the fixed plate 6, the output shaft of the second motor 17 is concentric with the rotary shaft 16, a second transmission assembly 18 is rotatably connected to the output shaft of the second motor 17, a lead screw 19 is rotatably connected to the top of the second transmission assembly 18, and the lead screw 19 is threadedly connected to the bottom of the material distribution plate 5;

[0044] like Figure 3 , Figure 5 As shown, the output shaft of motor 2 17 and the rotary shaft 16 are in a concentric position, so that the transmission group 2 18 can rotate synchronously with the flip frame 4 without affecting the transmission. The output of motor 2 17 drives the lead screw 19 to rotate through the transmission group 2 18. The lead screw 19 pushes the material distribution plate 5 to slide into the flip frame 4 to realize the displacement of the material distribution plate 5.

[0045] As a further embodiment of the present invention, a motor 7 is fixedly connected to the front end of the transmission assembly 8. The output end of the motor 7 passes through the transmission assembly 8 and is rotatably connected to the turntable 9. The output of the motor 7 drives the transmission assembly 8 to rotate, and the transmission assembly 8 drives the turntables 9 on both sides to rotate synchronously in the same direction.

[0046] As a further embodiment of the present invention, the flip frame 4, the material distribution plate 5, the telescopic plate 12 and the telescopic plate 20 are all made of heat-resistant grating material. The heat resistance must be guaranteed when in contact with high-temperature forged parts. The grating is used to increase air permeability, so that the airflow is stronger when the cooling fan 1 blows air into the inside of the flip frame 4.

[0047] As a further embodiment of the present invention, the front end of the flip frame 4 is provided with a slot 15 for sliding connection with the material distribution plate 5. A heat-conducting plate is fixedly connected inside the slot 15. The heat-conducting plate can conduct the heat on the material distribution plate 5, which is in direct contact with high-temperature parts, to the surface of the flip frame 4, and then be quickly cooled by the cooling fan 1.

[0048] As a further aspect of the present invention, the cooling fan 1 is internally connected with a plurality of fan blade groups that are equidistantly distributed. The plurality of fan blade groups can improve the air blowing efficiency of the cooling fan 1 and accelerate the cooling time.

[0049] As a further embodiment of the present invention, side baffles are fixedly connected to both sides of the top of the chain conveyor belt 3. The height of the two sides of the chain conveyor belt 3 is raised by the side baffles so that the parts will not fall off the chain conveyor belt 3 after they fall from the flipping frame 4 onto the chain conveyor belt 3.

[0050] Working principle: After being forged by the forging equipment, the parts are transported to the inside of the flipping frame 4 through the feeding hopper 2. The cooling fan 1 blows air from the top to cool the parts inside the flipping frame 4. The transmission group 8 drives the two turntables 9 to rotate counterclockwise. Under the action of the swing rods 10 on both sides, the flipping frame 4 rotates around the center of rotation. The purpose is to allow the parts that enter the inside of the flipping frame 4 through the feeding hopper 2 to roll back and forth inside the flipping frame 4 as the flipping frame 4 flips. After the parts inside the flipping frame 4 have cooled down, the material distribution plate 5 is pushed to slide into the inside of the flipping frame 4. At the same time, the connecting block 22 slides obliquely along the limit frame 23, so that the telescopic plate 20 slides backward with the material distribution plate 5. At the same time, the convex shaft 21 will stretch the telescopic plate 20 to slide horizontally. The connecting shaft 24 at the bottom of the material distribution plate 5 slides backward with the material distribution plate 5. The connecting shaft 24 pushes the lever 14 to drive the telescopic plate 12 to stretch the return spring 11 to slide horizontally, so that the bottom two sides of the flipping frame 4 open up.

[0051] When the material distribution plate 5 slides into the inside of the flipping frame 4, the slots 15 on both sides of the material distribution plate 5 are horizontally stretched to close the internal space of the flipping frame 4 to intercept uncooled parts. At the same time, the telescopic plate 12 at the bottom of the flipping frame 4 retracts, causing the bottom of the flipping frame 4 to open for conveying cooled parts. When the parts on the material distribution plate 5 have also flipped and cooled down with the flipping frame 4, the material distribution plate 5 is stretched back to its original position. During the reset process of the material distribution plate 5, the slots 15 gradually close, and the lever 14 gradually resets under the elastic force of the reset spring 11 after disengaging from the connecting shaft 24. During this process, the flipping frame 4 flips continuously, so the cooled parts on the slots 15 can fall into the bottom of the flipping frame 4 through the gradually enlarging opening of the slots 15, and then fall into the chain conveyor belt 3 through the gradually decreasing opening of the telescopic plates 12 on both sides of the bottom of the flipping frame 4.
