Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a multifunctional square bending device. Background Technology

[0002] Sheet metal work is a comprehensive cold processing technique for thin metal sheets (usually less than 6mm thick), including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Products processed using sheet metal techniques are called sheet metal. Bending devices are typically used when bending sheet metal parts.

[0003] A Chinese utility model patent application, CN222659737U, discloses a bending mechanism for a bending machine. The mechanism includes a bending machine body and a bending die base. It further includes: fixed rods on both sides of the bending die base; electric push rods fixed on both sides of the bottom surface of the bending machine body; a bending plate bolted to the output shaft of each electric push rod; a top plate fixedly connected to both ends of the bending plate; and a support block fixedly connected to the top of the top plate. A motor is located on the right side of the bending machine body, with a screw bolted to its output shaft. The other end of the screw is rotatably connected to the left side of the bending machine body surface. This utility model can adsorb debris inside the V-groove of the bending die base, reducing the hassle of manual cleaning and improving the accuracy of subsequent bending. It also lifts the bending die base by driving the top plate and support block, causing the bending die base to rotate, thus facilitating the switching of the V-groove surface of the bending die base by the operator.

[0004] Referring to the bending mechanism of the aforementioned bending machine, this mechanism cannot effectively process sheet metal into a closed square structure when bending sheet metal, thus limiting the use of the bending machine. Therefore, how to better process sheet metal parts into a closed square structure is an important problem that needs to be solved in the design of a multi-functional square bending device.

[0030] 1. In this application, the sheet metal to be processed is placed on the lower bending blade, and the upper bending blade descends to cooperate with the lower bending blade to bend the sheet metal. First, the two sides of the sheet metal are bent to form a "U" shape. Then, the center of the U-shaped sheet metal is placed on the lower bending blade, and the lower bending blade descends to bend the U-shaped sheet metal into a closed square structure, which facilitates better bending of the sheet metal and makes it into a closed square structure.

[0031] 2. The motor rotates, driving the threaded rod to rotate. The threaded rod then moves the moving block, which in turn moves the upper bending knife. This causes the other end of the upper bending knife to leave the upper bending knife seat on the right side, and the finished closed square sheet metal falls off the upper bending knife, making it easier to cut the finished sheet metal.

[0056] When the end of the fixing plate 2 403 is flush with the end of the mounting bracket 2 9, the snap-fit ​​groove 2 404 is directly opposite the snap-fit ​​rod 702.

[0057] The snap-fit ​​fixing structure 7 includes a movable frame 701, a snap-fit ​​rod 702, a threaded rod 703, and a rotating handle 704. The threaded rod 703 is rotatably connected to the front side wall of the first mounting frame 6 and the second mounting frame 9, respectively.

At this time, the snap-fit ​​groove 204 is facing the snap-fit ​​rod 702. Rotating the rotating handle 704 drives the threaded rod 703 to rotate. The rotation of the threaded rod 703 drives the moving frame 701 to move.

[0063] The sheet metal to be processed is placed on the lower bending cutter 401. The upper bending cutter 202 descends to cooperate with the lower bending cutter 401 to bend the sheet metal. First, the two sides of the sheet metal are bent to form a "U" shape. Then, the center of the U-shaped sheet metal is placed on the lower bending cutter 401. The lower bending cutter 401 descends to bend the U-shaped sheet metal into a closed square structure, which facilitates better bending of the sheet metal. After bending, the motor 502 rotates, driving the threaded rod 504 to rotate. The threaded rod 504 drives the moving block 505 to move, which in turn drives the upper bending cutter 202 to move. This causes the other end of the upper bending cutter 202 to leave the upper bending cutter 202 seat on the right side. The processed closed square sheet metal then falls from the upper bending cutter 202, which facilitates better unloading of the processed sheet metal.
