Description
Technical Field
[0001] This utility model relates to the field of bending technology for metal product processing, specifically a bending machine for metal product processing. Background Technology
[0002] Metal products are various products made from metal as the main raw material through a series of processing processes. Taking metal plates as an example, bending is often required during the metal plate processing.
[0003] The existing metal sheet bending device mainly consists of a worktable, a pneumatic cylinder, a bending die, and a lower die. When bending a metal sheet, the metal sheet to be bent is first placed on the worktable. Then, the pneumatic cylinder is used to move the bending die vertically downward. With the cooperation of the lower die, the bending process of the metal sheet can be achieved through the stamping and bending mechanism.
[0004] Existing metal sheet bending devices lack effective limiting mechanisms, causing the metal sheet to easily shift during bending and making it impossible to accurately control the bending position, thus affecting the bending effect. Furthermore, since curved surface bending and right-angle bending are common bending methods, existing metal sheet bending devices are not convenient for alternating between curved surface bending and right-angle bending during the bending process. They require switching to another bending machine to complete the bending of curved surfaces and right angles of the metal sheet, which greatly reduces the bending efficiency. Therefore, a bending machine for metal product processing is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a bending machine for metal product processing.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A bending machine for processing metal products, comprising a support base, on which a placement platform is mounted. Four limiting grooves are provided on the top side of the support base. A U-shaped movable frame is slidably assembled between every two limiting grooves. Limit plates are fixedly connected to the two top ends of each U-shaped movable frame. Two fixing plates are fixedly connected to the bottom side of the support base. A bidirectional lead screw is rotatably mounted on the two fixing plates, and the bidirectional lead screw passes through the U-shaped movable frame. A motor is mounted on one of the fixing plates, and the output end of the motor is connected to one end of the bidirectional lead screw. Two limiting grooves are provided on the two outer side walls of the placement platform. A limiting rod is provided in each limiting groove, and one end of the limiting rod is fixedly connected to the U-shaped movable frame. In the bending process of metal sheets, a limiting mechanism is used to prevent the sheet from shifting during bending. After the metal sheet is placed on the platform, the motor is started, causing the double-acting lead screw to rotate. This forces two U-shaped movable frames to move within the limiting grooves. With the cooperation of the limiting grooves and limiting rods, the U-shaped movable frames drive the limiting plates to move stably, bringing the limiting plates on both sides closer together until they contact the side walls of the metal sheet. At this point, the motor stops operating, effectively limiting and fixing the metal sheet. This prevents the sheet from shifting during bending, ensuring the accuracy of the bending angle and position. Precise limiting and fixing ensures that the metal sheet meets design requirements after bending, thereby improving the overall precision and quality of the product.
[0007] Preferably, vertical plates are fixed to both sides of the placement platform, and a first rotating wheel is installed between the two vertical plates via a first rotating shaft. A first motor is installed on one of the vertical plates, and the output end of the first motor is connected to one end of the first rotating shaft. A first lower mold and a second lower mold are fixed to the outer surface of the first rotating wheel. In order to achieve rapid alternation between curved bending and right-angle bending when bending the metal plate, a rotating wheel mechanism is set up to start the first motor, so that the first rotating wheel drives the first lower mold and the second lower mold to rotate, thereby enabling the second lower mold and the first lower mold to be rotated and interchanged.
[0008] Preferably, a fixed frame is fixedly connected to the support base, and a pneumatic cylinder is installed on the top side of the fixed frame. The pneumatic cylinder is equipped with a pneumatic rod, and a mounting frame is fixedly connected to the bottom end of the pneumatic rod. A second rotating wheel is installed inside the mounting frame through a second rotating shaft. A second motor is installed on one side wall of the mounting frame, and the output end of the second motor is connected to one end of the second rotating shaft. A first bending die and a second bending die are respectively fixed on the outer surface of the second rotating wheel. After the lower die is rotated and changed, the bending die needs to be rotated and changed accordingly. The second motor is started, so that the second rotating wheel drives the first bending die and the second bending die to rotate, thereby enabling the second bending die and the first bending die to be rotated and changed. Through the rotating wheel mechanism, the alternation of curved surface bending and right angle bending can be quickly realized without changing the equipment back and forth, so as to complete the bending processing of curved surface and right angle of metal plate, greatly improving the bending efficiency.
[0009] Preferably, a rectangular groove is provided on one side wall of the fixing frame, and a limiting block is provided in the rectangular groove. One side wall of the limiting block is fixed to the mounting frame. When bending, the cooperation between the rectangular groove and the limiting block enables the mounting frame to drive the bending die to move down stably, which facilitates better bending operation of the bending die.
[0010] The advantages of this utility model are:
[0011] 1. In order to prevent the metal plate from shifting during the bending process, this utility model sets up a limiting mechanism. The motor is started, which causes the bidirectional lead screw to rotate, forcing the two U-shaped movable frames to move within the limiting groove. With the cooperation of the limiting groove and the limiting rod, the U-shaped movable frames drive the limiting plates to move stably, so that the limiting plates on both sides move closer to each other until they contact the side wall of the metal plate. Then the motor stops working, which can effectively limit and fix the metal plate, preventing the metal plate from shifting during the bending process. This can ensure the accuracy of the bending angle and position. Through precise limiting and fixing, it can be ensured that the metal plate meets the design requirements after bending, thereby improving the overall precision and quality of the product.
[0012] 2. In order to achieve rapid alternation between curved bending and right-angle bending when bending metal plates, this utility model sets up a rotary switching mechanism. Starting the first motor causes the first rotating wheel to rotate the first and second lower dies, thereby allowing the second and first lower dies to be rotated and interchanged. Starting the second motor causes the second rotating wheel to rotate the first and second bending dies, thereby allowing the second and first bending dies to be rotated and interchanged. Through this rotary switching mechanism, the alternation between curved bending and right-angle bending can be achieved quickly without having to change equipment back and forth, thus completing the bending of curved and right-angled metal plates and greatly improving bending efficiency.

Two limiting grooves 9 are formed on both outer side walls of the placement platform 2. A limiting rod 10 is provided in each limiting groove 9, and one end of the limiting rod 10 is fixedly connected to the U-shaped movable frame 4. When bending the metal sheet, in order to... To prevent the metal sheet from shifting during bending, a limiting mechanism is used. After the metal sheet is placed on the placement platform 2, the motor 7 is started, causing the bidirectional lead screw 8 to rotate. This forces the two U-shaped movable frames 4 to move within the limiting groove 3. With the cooperation of the limiting groove 9 and the limiting rod 10, the U-shaped movable frames 4 drive the limiting plates 5 to move stably, bringing the two limiting plates 5 closer together until they contact the side wall of the metal sheet. At this point, the motor 7 stops operating, thus effectively limiting and fixing the metal sheet, preventing it from shifting during bending. This ensures the accuracy of the bending angle and position. Precise limiting and fixing guarantees that the metal sheet meets design requirements after bending, thereby improving the overall precision and quality of the product.
[0022] Please see Figure 1-2 and Figure 4-5As shown, vertical plates 11 are fixed to both sides of the placement platform 2. A first rotating wheel 12 is installed between the two vertical plates 11 with a first rotating shaft. A first motor 13 is installed on one of the vertical plates 11. The output end of the first motor 13 is connected to one end of the first rotating shaft. A first lower mold 14 and a second lower mold 15 are fixed to the outer surface of the first rotating wheel 12. A fixed frame 16 is fixed to the support base 1. A pneumatic cylinder 17 is installed on the top side of the fixed frame 16. The pneumatic cylinder 17 is equipped with a pneumatic rod. A mounting frame 18 is fixed to the bottom end of the pneumatic rod. A second rotating wheel 19 is installed in the mounting frame 18 with a second rotating shaft. A second motor 20 is installed on one side wall of the mounting frame 18. The output end of the second motor 20 is connected to one end of the second rotating shaft. The outer surface of the second rotating wheel 19 is fixed to the first lower mold 14 and the second lower mold 15. There are a first bending die 21 and a second bending die 22. When bending a metal plate, in order to achieve rapid alternation between curved bending and right-angle bending, a rotary switching mechanism is set up. The first motor 13 is started, which causes the first rotating wheel 12 to drive the first lower die 14 and the second lower die 15 to rotate, thereby enabling the second lower die 15 and the first lower die 14 to be rotated and swapped. The second motor 20 is started, which causes the second rotating wheel 19 to drive the first bending die 21 and the second bending die 22 to rotate, thereby enabling the second bending die 22 and the first bending die 21 to be rotated and swapped. Through the rotary switching mechanism, the alternation between curved bending and right-angle bending can be achieved quickly without changing equipment back and forth, thus completing the bending of curved and right-angle metal plates and greatly improving the bending efficiency.
[0023] A rectangular groove 23 is provided on one side wall of the fixed frame 16, and a limit block 24 is provided in the rectangular groove 23. One side wall of the limit block 24 is fixed to the mounting frame 18. When bending, the rectangular groove 23 and the limit block 24 cooperate to enable the mounting frame 18 to drive the bending die to move down stably, which facilitates the bending die to perform better bending operations.
[0024] Working Principle: Existing metal sheet bending devices lack effective limiting mechanisms, causing the metal sheet to easily shift during bending, making it impossible to precisely control the bending position and thus affecting the bending effect. Furthermore, since curved surface bending and right-angle bending are common bending methods, existing metal sheet bending devices cannot easily alternate between these two methods; they require switching to another bending machine to complete the bending of curved surfaces and right angles, greatly reducing bending efficiency. Therefore, to address the above problems... The problem proposes a bending machine for metal product processing. To prevent the metal sheet from shifting during bending, a limiting mechanism is installed. After the metal sheet is placed on the placement table 2, the motor 7 is started, causing the bidirectional lead screw 8 to rotate. This forces two U-shaped movable frames 4 to move within the limiting groove 3. With the cooperation of the limiting groove 9 and the limiting rod 10, the U-shaped movable frames 4 drive the limiting plates 5 to move stably, bringing the two limiting plates 5 closer together until they contact the sidewalls of the metal sheet. Afterwards, the motor 7 stops operating, effectively limiting and fixing the metal plate, preventing it from shifting during bending. This ensures the accuracy of the bending angle and position. Precise limiting and fixing guarantees that the metal plate meets design requirements after bending, thereby improving the overall precision and quality of the product. To achieve rapid alternation between curved and right-angle bending during metal plate bending, a rotary switching mechanism is used. The first motor 13 is started, causing the first rotating wheel 12 to rotate the first lower die 14 and the second lower die 15, allowing for the rotational interchange of the second lower die 15 and the first lower die 14. The second motor 20 is started, causing the second rotating wheel 19 to rotate the first bending die 21 and the second bending die 22, allowing for the rotational interchange of the second bending die 22 and the first bending die 21. This rotary switching mechanism allows for rapid alternation between curved and right-angle bending without the need for repeated equipment changes, significantly improving bending efficiency.
