Description

Technical Field

[0001] This utility model relates to the field of metal sheet technology, specifically to a bending machine frame and a bending machine. Background Technology

[0002] In the field of sheet metal processing, bending machines, as one of the core pieces of equipment, are widely used in industries such as automobile manufacturing, aerospace, and home appliance production. Traditional bending machines typically employ a unidirectional upper die downward pressing structure. Their working principle involves hydraulically or mechanically driving the upper die downwards to cooperate with a fixed lower die to complete the sheet metal bending. However, existing equipment can only achieve unidirectional bending, usually with the upper die pressing down. When processing parts requiring bidirectional bending, such as Z-shaped structures, multiple adjustments to the sheet metal clamping position or die replacements are necessary, leading to reduced processing efficiency and accumulated repetitive positioning errors, making it difficult to meet high-precision manufacturing requirements. Traditional lower dies often use a single V-groove fixing method, which has poor adaptability to sheets with large thickness variations. Furthermore, the V-groove structure leaves indentations on the sheet metal surface, affecting the finished quality of the finished product.

[0003] Therefore, there is an urgent need for a bending machine with bidirectional bending capability that can adapt to various thicknesses of sheet metal, thereby improving bending efficiency and adaptability. Utility Model Content

[0004] To address the aforementioned shortcomings, this utility model provides a bending machine frame and a bending machine that can achieve bidirectional bending, adapt to plates of various thicknesses, and improve bending efficiency and equipment adaptability.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: a bending machine frame, including a worktable, with a support leg fixedly connected to the bottom of the worktable, an upper fixed frame fixedly connected to the top of the worktable, and a lower fixed frame fixedly connected to the bottom of the worktable. One side of the lower fixed frame is flush with one side of the upper fixed frame. A movable seat one and a movable seat two are vertically slidably connected inside the upper fixed frame. A tool holder one is fixedly connected to the bottom of the movable seat one, and a mold mounting seat one is fixedly connected to the bottom of the movable seat two. A movable seat three is vertically slidably connected inside the lower fixed frame, located directly below the movable seat one. A tool holder two is fixedly connected to the top of the movable seat three. A mold mounting seat two is fixedly connected to the top of the worktable and directly below the movable seat two. An adjustment component is also provided on one side of each mold mounting seat one and mold mounting seat two.

[0006] Preferably, the inner wall of the upper fixed frame is provided with a first sliding groove adapted to the movable seat one, the inner wall of the fixed frame is also provided with a second sliding groove adapted to the movable seat two, and the inner wall of the lower fixed frame is also provided with a third sliding groove adapted to the movable seat three, and the first sliding groove and the third sliding groove are connected.

[0007] Preferably, the top two sides of the workbench, away from the lower fixed frame, are fixedly connected to support seats, and a conveying roller is provided between the two support seats.

[0008] Preferably, the adjusting assembly includes a threaded rod and a threaded cylinder. The threaded rod is threadedly connected to the center of the threaded cylinder. A first limiting block is fixedly connected to one end of the threaded rod, and a hexagonal block is fixedly connected to the other end of the threaded rod. A second limiting block is fixedly connected to the end of the threaded cylinder near the first limiting block. A hexagonal surface is provided on the surface of the threaded cylinder away from the second limiting block. A first locking nut is threadedly connected to the surface of the threaded rod near the hexagonal surface, and a second locking nut is threadedly connected to the surface of the threaded cylinder.

[0009] A bending machine includes a bending machine frame as described above. A first actuator for driving a third moving seat to move vertically is provided at the bottom of the lower fixed frame. A second actuator for driving a first moving seat to move vertically and a third actuator for driving a second moving seat to move vertically are provided at the top of the inner wall of the upper fixed frame. A first bending die is fixedly connected to the surface of a first tool holder, and a second bending die is fixedly connected to the surface of a second tool holder. A first bending die is fixedly connected to the surface of a first die mounting base via an adjusting assembly, and a second bending die is fixedly connected to the surface of a second die mounting base via an adjusting assembly.

[0010] Preferably, the first actuator, the second actuator, and the third actuator are servo electric cylinders.

[0011] The present invention adopts the above-mentioned technical solution, and its beneficial effects include: the bending machine frame and bending machine, by setting bending upper dies at both the top and bottom of the plate, can achieve bending from both the top and bottom, avoiding the flipping operation in traditional processing and improving processing efficiency; at the same time, during the bending process, the plate is clamped by two bending lower dies, which improves the stability of the bending process, prevents slippage during bending, and thus ensures processing accuracy; by adjusting the position of the bending lower die by adjusting the component, the distance between one side of the bending lower die and the bending upper die can be adjusted, which can adapt to bending plates of different thicknesses, avoids changing dies, and improves adaptability.

[0020] A mold mounting base 11 is fixedly connected to the top of the workbench 1 and directly below the movable base 6. An adjustment assembly is also provided on one side of the mold mounting base 8 and the mold mounting base 11. The adjustment assembly includes a threaded rod 17 and a threaded cylinder 18.

During the downward bending, the second actuator 26 drives the moving seat 5 to press down, and the upper bending die 28 completes the forward bending. Then, the lower bending die 30 separates from the sheet metal under the action of the third actuator 27. The sheet metal moves forward a distance and is then pressed by the lower bending die 30. During the upward bending, the first actuator 25 drives the moving seat 9 to push up, and the upper bending die 29 completes the reverse bending.
