Description

Technical Field

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

[0002] In the production and forming process of various boxes, such as electrical boxes and metering boxes, metal sheets need to be bent and shaped by bending machines. Under the pressure of the bending machine, the metal sheet first undergoes elastic deformation and then enters plastic deformation. At the beginning of the plastic bending stage, the sheet is freely bent. As the upper or lower die applies pressure to the sheet, the sheet gradually comes into close contact with the inner surface of the V-groove of the lower die. The pressure continues until the stroke ends, so that the upper and lower dies and the sheet are in full contact at three points, completing a bending process. Bending machines are mostly used for right-angle bending of metal products.

[0003] Existing bending machines require manual placement of sheet metal parts between two bending dies, which is inefficient and prone to danger. When bending multiple sides of a metal sheet, the direction of the sheet metal needs to be manually adjusted after each side is bent before bending the other side. Therefore, manually adjusting the direction of the sheet metal is a complex process with low processing efficiency. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal bending machine for box body production, comprising a base, columns installed around the base, movable beams mounted on the columns, an upper beam installed on the top of the columns, and a hydraulic cylinder installed on the top of the upper beam. The output end of the hydraulic cylinder is fixedly connected to the movable beam. A bending upper die is bolted to the lower part of the movable beam. A bending lower die is installed on the base. A feeding mechanism is installed on the rear side of the base. The feeding mechanism includes a support, a lifting cylinder, a rotary cylinder, a pallet, a lifting cylinder, and a pressure block. A platform is provided in the middle of the support. The lifting cylinder is installed at the lower part of the support. The rotary cylinder is installed on the output end of the lifting cylinder. The pallet is installed on the turntable of the rotary cylinder. The lifting cylinder is installed at the top of the support. The pressure block is installed on the output end of the lifting cylinder.

[0006] Furthermore, the movable beam is fitted with guide sleeves around its perimeter and is movably connected to the column through the guide sleeves.

[0007] Furthermore, the lower part of the movable beam is bolted to a clamping block, which is clamped onto the upper bending die.

[0008] Furthermore, the upper bending die and the lower bending die are positioned correspondingly, and the bracket is installed on the rear side of the base by bolts.

[0009] Furthermore, the platform is flush with the top surface of the lower bending die, and an opening is provided on the platform.

[0010] Furthermore, the tray is located in the opening and is flush with the top surface of the platform, and the pressure block is located above the tray.

[0011] Compared with the prior art, this utility model provides a sheet metal bending machine for box body production, which has the following beneficial effects:

[0012] This sheet metal bending machine for box production places the metal sheet on the platform of the feeding mechanism, with the part to be bent located on the lower bending die. The lifting cylinder drives the pressure block to hold the sheet, and the upper bending die presses down to bend the metal sheet. After one side of the metal sheet is bent, the lifting cylinder lifts the metal sheet a certain distance, and then the rotary cylinder rotates the metal sheet by a certain angle to adjust the side orientation of the metal sheet. This can replace the traditional manual repositioning of the metal sheet, saving labor and improving processing efficiency. Attached Figure Description

An upper beam 4 is installed on the top of the columns 2, and a hydraulic cylinder 5 is installed on the top of the upper beam 4. The output end of the hydraulic cylinder 5 is fixedly connected to the movable beam 3. A bending upper die 6 is fastened to the lower part of the movable beam 3 by bolts.

The metal sheet is placed on the platform 87 of the feeding mechanism 8, with the part to be bent located on the bending lower die 7. A lifting cylinder 85 drives a pressure block 86 to hold the sheet. After the bending upper die 6 presses down, it bends the metal sheet. After bending one side of the metal sheet, a lifting cylinder 82 lifts the metal sheet a certain distance, and then a rotating cylinder 83 rotates the metal sheet a certain angle to achieve side orientation adjustment of the metal sheet. This can replace the traditional manual repositioning of the metal sheet, save labor, and improve processing efficiency.

[0019] The feeding mechanism 8 includes a support 81, a lifting cylinder 82, a rotary cylinder 83, a pallet 84, a lifting cylinder 85, and a pressure block 86.

[0021] In this implementation plan, the column 2 and the guide sleeve 9 mainly serve to guide and position, ensuring that the movable beam 3 moves along the predetermined trajectory, guaranteeing the stable operation of the movable beam 3, and preventing it from tilting.

[0022] Specifically, the lower part of the movable beam 3 is connected to a clamping block 10 by bolts, and the clamping block 10 is clamped on the bending upper die 6.

[0027] In this implementation scheme, the opening 88 is designed to allow space for the installation and operation of the tray 84.

[0028] Specifically, the tray 84 is located in the opening 88 and is flush with the top surface of the platform 87, and the pressure block 86 is located above the tray 84.

[0029] In this embodiment, the metal plate is placed on the platform 87 of the feeding mechanism 8 and supported by the pallet 84.

[0030] In use, the metal plate is placed on the platform 87 of the feeding mechanism 8, with the part to be bent located on the lower bending die 7. The lifting cylinder 85 drives the pressure block 86 to hold the metal plate, and the upper bending die 6 presses down to bend the metal plate. After one side of the metal plate is bent, the lifting cylinder 82 lifts the metal plate a certain distance, and then the rotary cylinder 83 rotates the metal plate a certain angle to achieve side orientation adjustment of the metal plate. This can replace the traditional manual repositioning of the metal plate, saving labor and improving processing efficiency.

[0031] In summary, this sheet metal bending machine for box production places the metal sheet on the platform 87 of the feeding mechanism 8, with the part to be bent located on the lower bending die 7. The lifting cylinder 85 drives the pressure block 86 to hold the sheet metal, and the upper bending die 6 presses down to bend the metal sheet.
