Technical Field

[0001] The utility model relates to the technical field of metal plate processing, in particular to a metal plate bending machine. Background Art

[0002] Sheet metal is metal formed into thin, flat sheets by industrial methods. Sheet metal is one of the basic forms used in metalworking, and it can be cut and bent into a variety of shapes. Countless everyday items are made from sheet metal. Bending of sheet metal is a type of sheet metal.

[0003] At present, when metal sheet bending mechanisms are actually used, most of them directly fix one end of the metal sheet and then bend the other end. However, the structure for fixing the metal sheet is mostly a fixed frame structure, so it can only fix metal sheets of one width and has low applicability. When it is necessary to bend metal sheets of different widths, different fixing structures are needed to fix the metal sheets. It is troublesome to replace the fixing structures back and forth, and the use effect is not good enough.

[0004] The existing Chinese patent with announcement number CN218656241U discloses a metal sheet bending mechanism, which specifically relates to the field of metal sheet processing technology, including a processing table, a fixing component and a bending component are provided at the top of the processing table, the fixing component includes a fixed vertical plate fixedly arranged on the top of the processing table, two symmetrical clamping plates are provided on one side of the fixed vertical plate, two movable grooves are opened on one side of the fixed vertical plate, two movable blocks are provided inside the movable grooves, the outer sides of the four movable blocks are respectively fixedly connected to the inner sides of the two clamping plates, and a threaded rod is provided inside the movable grooves.
