Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a bending device used for processing office furniture plates. Background Art

[0002] In the production process of office furniture, some metal plates often need to be bent. The bending machine is an important equipment for bending and forming workpieces in the sheet metal industry. Its function is to press metal plates into parts of various shapes according to process requirements;

[0003] After checking the publication number: CN220837344U, an easy-to-install bending mechanism of a bending machine is disclosed. This technology discloses "an easy-to-install bending mechanism of a bending machine, which relates to the technical field of bending machines, including a base, a bending machine body is installed on the upper end of the base, a workbench is installed on one end of the bending machine body, a lower mold is movably connected to the upper end of the workbench, a rotating plate is installed on one end of the workbench, a fixing mechanism is installed inside the rotating plate, a pressing plate is installed on one end of the bending machine body close to the workbench, and a connecting block is installed on both ends of the pressing plate, and an upper positioning block and a lower positioning block are symmetrically installed on one end of the connecting block, and a fixing block is symmetrically fixedly connected to one end of the upper positioning block, and a connecting mechanism is symmetrically installed inside the fixing block, a bending cutter head is installed on the bottom end of the pressing plate, and an adjusting mechanism is symmetrically installed on the opposite ends of the lower positioning block" and other technical solutions, which have "convenient for users to install and disassemble the bending mechanism of the bending machine, and improve the work efficiency of users" and other technical effects;

However, the number of tool grooves that can be set on the lower mold is limited, which makes the adjustment of the bending angle not flexible enough and cannot meet the strict requirements for diversified bending angles in furniture manufacturing.
