Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy plate processing technology, and in particular to an aluminum alloy plate bending device for processing mechanical parts. Background Technology

[0002] Aluminum alloy sheet is a type of sheet material made of aluminum and other elements. It is lightweight, corrosion-resistant, and high-strength, and is widely used in aerospace, automotive, and construction industries. Bending aluminum alloy sheet is the process of bending a flat sheet into a desired shape to meet specific design requirements and application needs. Bending can change the bending angle, curve shape, and size of the sheet, and is commonly used in various industrial and commercial applications, such as structural materials, heat exchangers, packaging materials, and electronic products.

[0003] A search revealed a Chinese patent document, CN215544413U, which discloses an aluminum alloy plate bending device for machining mechanical parts. This device includes a base plate, a support platform, a motor, a notched gear, a first fixed rod, and a first spur gear. The support platform is located on the upper right front side of the base plate, and the motor is mounted on the upper side of the support platform. The notched gear is located on the output shaft of the motor. The first fixed rod is located in the middle of the upper front side of the base plate, and the first spur gear is rotatably mounted on the first fixed rod. The first spur gear cooperates with the notched gear. The device includes a motor and a rotating block, which allows the rotating block to bend the aluminum alloy plate without the need for manual bending by the worker, thereby reducing the labor intensity of the worker and effectively improving the worker's work efficiency.

[0004] However, during the use of this aluminum alloy plate bending device, the worker still needs to move the aluminum alloy plate forward onto the rotating block, which prevents the device from automatically feeding the material, increasing the worker's labor intensity. At the same time, the torsion spring will lose elasticity after long-term use, which will prevent the device from resetting, affecting the subsequent use of the device. In addition, the device is relatively complex and troublesome to maintain, reducing the practicality of the device. Utility Model Content

[0015] (III) Beneficial Effects

[0016] This utility model provides an aluminum alloy plate bending device for machining mechanical parts. It has the following advantages:

[0017] 1. Using the feeding assembly, the aluminum alloy sheet to be bent is first placed in the placement frame. The geared motor is started, which drives the first feeding roller to rotate. The rotation of the geared motor drives the first transmission sprocket to rotate. The first transmission sprocket is connected to the second transmission sprocket through the transmission chain, thereby driving the cam to rotate. The cam drives the rotating wheel to rotate. When the cam rotates on the arc surface, it pushes the rotating wheel outward. The rotating wheel drives the lever to move outward, thereby driving the inclined block to move outward. At this time, the spring is stretched. When the cam rotates to the vertical plane, the cam separates from the rotating wheel. Using the elastic potential energy of the spring, the lever is pulled inward, thereby driving the inclined block to move inward. This drives the pusher block to push the aluminum alloy sheet to be bent through the discharge chute onto the conveyor belt.

[0018] 2. By using the folding assembly, the worker holds the handrail and presses it down. The handrail moves the connecting plate downward, and the connecting plate moves the connecting rod downward. This causes the connecting rod to move along the through groove while simultaneously moving the limiting block within the limiting groove. As a result, the connecting rod will follow the through groove and form a C-shape, thus causing the pressed aluminum alloy plate to also become C-shaped. Through the cooperation between the connecting rod and the groove, the connecting rod can slide in different directions. After completing the bend, it can return to the initial position, facilitating subsequent bending operations and improving the practicality of the device. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1

[0027] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides an aluminum alloy plate bending device for processing mechanical parts, including a base plate 1, a support frame 2 fixedly connected to the upper surface of the base plate 1, a conveyor belt 3 arranged inside the support frame 2, a bending component 4 arranged on one side of the support frame 2, and a feeding component 5 arranged on the side of the support frame 2 away from the bending component 4.

[0028] The feeding assembly 5 includes a housing fixedly connected to one side of the support frame 2. A discharge chute 6 is provided on one side of the housing. An L-shaped plate 501 is symmetrically arranged inside the housing. A movable groove 502 is provided on the outer surface of the L-shaped plate 501. A first connecting block 503 is fixedly connected to the bottom wall of the movable groove 502. A rotating shaft is provided between the two first connecting blocks 503. A first feeding roller 506 is sleeved on the outer surface of the rotating shaft. A second telescopic rod 508 is fixedly connected to the middle of the top wall of the movable groove 502. One end of the second telescopic rod 508 is fixedly connected to a second connecting block 50. 4. A telescopic spring 507 is provided between the inner top wall of the movable groove 502 and the second connecting block 504. A second rotating shaft is provided between the two second connecting blocks 504. A second feeding roller 505 is sleeved on the outer surface of the second rotating shaft. One end of the first rotating shaft passes through the first connecting block 503 and is fixedly connected to the first transmission sprocket 511. A third rotating shaft is inserted on one side of the lower part of the two L-shaped plates 501. One end of the third rotating shaft is fixedly connected to the second transmission sprocket 5111. The first transmission sprocket 511 and the second transmission sprocket 5111 are connected by a transmission chain 513.

[0029] Specifically, a reduction motor 512 is fixedly connected to the outer surface of the first transmission sprocket 511; a cam 514 is sleeved on the outer surface of the rotating shaft; a placement block 515 is fixedly connected to the inner bottom wall of the outer casing; a placement frame 518 is fixedly connected to the inner top wall of the outer casing; a placement groove 519 is formed in the inner bottom wall of the placement frame 518; a fixing plate 520 is fixedly connected to the lower surface of the placement frame 518; an inclined groove communicating with the placement groove 519 is formed on the fixing plate 520; an inclined block 521 is slidably connected inside the inclined groove; and the inclined block 521... A lever 516 is rotatably connected to the lower surface, and the other end of the lever 516 is rotatably connected to the placement block 515. A rotating wheel 517 corresponding to the cam 514 is provided on the lever 516. A pusher block 522 is fixedly connected to the upper surface of the inclined block 521. A spring 523 is provided between the lower surface of the fixing plate 520 and the lever 516. A connecting post 509 is provided between the first connecting block 503 and the second connecting block 504. The position of the feeding port between the first feeding roller 506 and the second feeding roller 505 corresponds to the position of the discharge trough 6.

[0030] Next, the aluminum alloy sheet to be bent is placed in the placement frame 518. The reduction motor 512 is started, which drives the first feeding roller 506 to rotate. The rotation of the reduction motor 512 drives the first transmission sprocket 511 to rotate. The first transmission sprocket 511 is connected to the second transmission sprocket 5111 via the transmission chain 513, thereby driving the cam 514 to rotate. The cam 514 drives the rotating wheel 517 to rotate. When the cam 514 rotates on the arc surface, it moves towards... The external push wheel 517 drives the lever 516 to move outward, thereby driving the inclined block 521 to move outward. At this time, the spring 523 is stretched. When the cam 514 rotates to the vertical plane, the cam 514 separates from the wheel 517. Using the elastic potential energy of the spring 523, the lever 516 is pulled inward, thereby driving the inclined block 521 to move inward, thereby driving the pusher block 522 to push the aluminum alloy plate that needs to be bent through the discharge chute 6 to the conveyor belt 3.

[0031] Example 2

[0032] Reference Figure 1 , Figure 3 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] The bending assembly 4 includes L-shaped connecting plates 401 symmetrically arranged on the outer surface of the support frame 2. The outer surface of the L-shaped connecting plates 401 is provided with a through groove 402. The outer surface of the support frame 2 is rotatably provided with a connecting plate 403 located outside the L-shaped connecting plates 401. A limiting groove 404 is provided on the opposite side of the two connecting plates 403. A limiting block 405 is slidably arranged inside the limiting groove 404. A connecting rod 407 is inserted inside the through groove 402, and both ends of the connecting rod 407 are respectively connected to the limiting block 405.

[0034] Specifically, the through groove 402 has a U-shaped structure, the outer surface of the connecting plate 403 has a groove 406 that communicates with the limiting groove 404, the end of the connecting rod 407 passes through the limiting block 405 and extends to the outside of the groove 406, the end of the connecting rod 407 is fixedly fitted with a limiting plate 408, a fixing block 410 located between two L-shaped connecting plates 401 is provided on one side of the support frame 2, and a handrail 409 is provided on the L-shaped connecting plate 401, and a limiting plate 411 is fixedly connected to the upper surface of the support frame 2.

[0035] Furthermore, through the folding component 4, the worker holds the handle 409 and presses it down. The handle 409 drives the connecting plate 403 to move downward, and the connecting plate 403 drives the connecting rod 407 to move downward. This causes the connecting rod 407 to move along the through groove 402 while simultaneously moving the limiting block 405 within the limiting groove 404. This allows the connecting rod 407 to follow the through groove 402 and exit in a C-shape, thus causing the pressed aluminum alloy plate to also become C-shaped. Through the cooperation between the connecting rod 407 and the groove 406, the connecting rod 407 can slide in different directions. After completing the bending, it can return to its initial position, facilitating subsequent bending operations and improving the practicality of the device.

[0036] Working Principle: In use, the aluminum alloy sheet to be bent is placed in the placement frame 518. Starting the reduction motor 512 drives the first feeding roller 506 to rotate. The rotation of the reduction motor 512 drives the first transmission sprocket 511 to rotate. The first transmission sprocket 511 is connected to the second transmission sprocket 5111 via the transmission chain 513, thereby driving the cam 514 to rotate. The cam 514 drives the rotating wheel 517 to rotate. When the cam 514 rotates on the arc surface, it pushes the rotating wheel 517 outward. The rotating wheel 517 drives the lever 516 to move outward, thereby moving the inclined block 521 outward. At this time, the spring 523 is stretched. When the cam 514 rotates to the vertical plane, the cam 514 separates from the rotating wheel 517. Using the elastic potential energy of the spring 523, the lever 516 is pulled inward, thereby moving the inclined block 521 inward. This causes the pusher block 522 to push the aluminum alloy plate to be bent through the discharge chute 6 to the conveyor belt 3. The conveyor belt 3 moves the aluminum alloy plate to the limiting plate 411. Through the cooperation of the limiting plate 411 and the fixing block 410, the worker holds the handrail 409 and presses it down. The handrail 409 drives the connecting plate 403 to move down. The connecting plate 403 drives the connecting rod 407 to move down. As the connecting rod 407 moves along the through groove 402, it drives the limiting block 405 to move in the limiting groove 404. This causes the connecting rod 407 to walk out of the through groove 402 in a C-shape, so that the pressed aluminum alloy plate also becomes C-shaped. Through the cooperation of the connecting rod 407 and the groove 406, the connecting rod 407 can slide in different directions. After completing the bending, it can return to the initial position, which facilitates subsequent bending operations and improves the practicality of the device.
