Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a metal sheet bending machine for aluminum door processing. Background Technology

[0002] In the production and processing of aluminum doors, the edge-folding process of metal sheets is crucial, as it directly affects the quality, appearance, and overall performance of the aluminum doors.

[0003] Some existing bending machines are equipped with replaceable molds. When changing molds, the new mold is accurately aligned and installed, and the fixing device is tightened. However, existing metal sheet bending machines for aluminum door processing have many problems. On the one hand, the bending efficiency is low. Early bending equipment mostly used manual operation or simple mechanical drive, which resulted in unstable power output and cumbersome operation, leading to a long bending process. When facing the design requirements of aluminum doors of different specifications and shapes, it is difficult to quickly and accurately change and position the molds, resulting in long mold replacement time and difficulty in guaranteeing the positional accuracy after replacement, which in turn affects the bending quality. Utility Model Content

The electric push rod provides stable and controllable power, making the folding process fast and efficient, greatly improving the folding processing efficiency of aluminum door metal sheets.

[0008] Preferably, an upper mold is provided below the limiting plate, and a lower mold is provided above the worktable. The bottom end of the upper mold and the top end of the lower mold are in contact with the metal plate. The folding device drives the limiting plate and the upper mold to press down by means of an electric push rod, and cooperates with the lower mold to fold the metal plate by extrusion.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-5 This utility model provides a technical solution: a metal sheet bending machine for aluminum door processing, comprising:

[0025] Workbench 1, with a folding device 2 fixedly connected to the top of the workbench 1. The folding device 2 folds the metal plate by pressing. An adjustment device 3 is slidably connected to the inner wall of the workbench 1. The adjustment device 3 locks the folding device 2. The folding device 2 can be adjusted and replaced by the adjustment device 3. Then the object to be processed is placed on the workbench 1 for folding.

[0026] The folding device 2 includes a U-shaped frame 20. An electric push rod 21 is fixedly connected to the inner wall of the U-shaped frame 20. A limit plate 22 is fixedly connected to the bottom end of the electric push rod 21. The outer wall of the limit plate 22 is slidably connected to the inner wall of the adjusting device 3. The bottom end of the U-shaped frame 20 is fixedly connected to the table surface of the workbench 1. Then, the metal plate to be processed is placed between the upper mold 23 and the lower mold 24. The electric push rod 21 in the folding device 2 is activated. The electric push rod 21 is supported by the U-shaped frame 20 and pushes the bottom end of the U-shaped frame 20. The fixed end connection of the limiting plate 22 moves downward. Since the upper mold 23 is provided below the limiting plate 22, the upper mold 23 will move downward synchronously with the limiting plate 22. At this time, the metal plate to be folded is placed on the top of the lower mold 24 located above the worktable 1. The bottom end of the upper mold 23 gradually approaches and contacts the metal plate. As the electric push rod 21 continuously applies pressure, the upper mold 23 and the lower mold 24 cooperate to plastically deform the metal plate by extrusion, thereby completing the folding operation.

[0027] An upper mold 23 is provided below the limiting plate 22, and a lower mold 24 is provided above the worktable 1. The bottom end of the upper mold 23 and the top end of the lower mold 24 are in contact with the metal plate. After the folding is completed, the electric push rod 21 retracts, driving the upper mold 23 and the limiting plate 22 to rise and reset, taking out the processed metal plate, and performing the next round of folding.

[0028] The adjustment device 3 includes a clamping plate 30. The inner wall of the clamping plate 30 is symmetrically threaded with a one-way screw 31. The inner wall of the clamping plate 30 is symmetrically slidably connected to the outer wall of the limiting plate 22. The outer wall of the clamping plate 30 is symmetrically slidably connected to the outer wall of the upper mold 23. First, the upper mold 23 and the lower mold 24 to be used are installed by sliding. Since the outer wall of the limiting plate 22 is symmetrically slidably connected with the clamping plate 30, and the outer wall of the clamping plate 30 is slidably connected to the outer wall of the upper mold 23, the clamping plate 30 is slid into the slot of the upper mold 23 for limiting and holding. Since there are two clamping plates 30, and they are locked by the threaded connection between the one-way screw 31 and the threaded sleeve, the upper mold 23 can be replaced while being fixed.

[0029] The adjustment device 3 also includes a sliding clamp 32. The bottom end of the sliding clamp 32 is fixedly connected to a slider 33. The outer wall of the sliding clamp 32 is symmetrically slidably connected to the outer wall of the lower mold 24. The outer wall of the slider 33 is slidably connected to the inner wall of the worktable 1 through a dovetail groove, and the dovetail groove is opened inside the worktable 1. Then the lower mold 24 is installed so that the sliding clamp 32 slides on the top of the worktable 1. Since the bottom end of the sliding clamp 32 is fixedly connected to the slider 33, and the slider 33 is slidably connected to the inner wall of the worktable 1 through a dovetail groove, and there are two sliding clamps 32, the lower mold 24 is installed and fixed to the sliding clamp 32 by sliding.

[0030] The outer wall of the sliding clamp 32 is symmetrically fixed with locking strips 34, and the outer wall of the locking strips 34 is slidably connected with a limiting frame 35. The inner walls of the locking strips 34 and the limiting frame 35 are slidably connected with pins 36. After the mold 24 is replaced or installed, the locking strips 34 symmetrically fixed to the outer wall of the sliding clamp 32 play a role, sliding the limiting frame 35 on the outer wall of the locking strips 34 to a suitable position, and then inserting the pins 36. Through the combination of the locking strips 34, the limiting frame 35 and the pins 36, the sliding clamp 32 is reliably locked, preventing the mold position from changing due to vibration and other factors during the folding process.

[0031] In use, the folding device 2 is adjusted and replaced by adjusting device 3, and then the object to be processed is placed on top of workbench 1 for folding.

[0032] First, the upper mold 23 and lower mold 24 are installed by sliding. Since the outer wall of the limiting plate 22 is symmetrically connected with the clamping plate 30, and the outer wall of the clamping plate 30 is slidably connected with the outer wall of the upper mold 23, the clamping plate 30 is slid into the slot of the upper mold 23 for limiting and holding. Since there are two clamping plates 30, and they are locked by the threaded connection between the single screw 31 and the threaded sleeve, the upper mold 23 can be replaced while being fixed.

[0033] Then the lower mold 24 is installed, so that the sliding clamp 32 slides on the top of the worktable 1. Since the bottom end of the sliding clamp 32 is fixedly connected to the slider 33, and the slider 33 is slidably connected to the inner wall of the worktable 1 through the dovetail groove, and there are two sliding clamps 32, the lower mold 24 is installed and fixed to the sliding clamp 32 by sliding.

[0034] Once the mold 24 is replaced or installed, the locking strip 34, which is symmetrically fixed to the outer wall of the sliding clamp 32, comes into play. It slides the limiting frame 35 on the outer wall of the locking strip 34 to a suitable position, and then inserts the pin 36. Through the combination of the locking strip 34, the limiting frame 35 and the pin 36, the sliding clamp 32 is reliably locked, preventing the mold position from changing due to vibration or other factors during the folding process.

[0035] The metal plate to be processed is then placed between the upper mold 23 and the lower mold 24. The electric push rod 21 in the folding device 2 is activated. The electric push rod 21 is supported by the U-shaped frame 20 and pushes the limiting plate 22, which is fixedly connected at the bottom, to move downward. Since the upper mold 23 is set below the limiting plate 22, the upper mold 23 will move downward synchronously with the limiting plate 22. At this time, the metal plate to be folded is placed on the top of the lower mold 24 located above the worktable 1. The bottom of the upper mold 23 gradually approaches and contacts the metal plate. As the electric push rod 21 continues to apply pressure, the upper mold 23 and the lower mold 24 cooperate to cause the metal plate to undergo plastic deformation by extrusion, thereby completing the folding operation.

[0036] After the folding is completed, the electric push rod 21 retracts, driving the upper mold 23 and the limit plate 22 to rise and reset, taking out the processed metal plate, and proceeding to the next round of folding.
