Description

Technical Field

[0002] Metal components refer to various components made of metal materials. When such metal components are subjected to bending processing, a metal component bending mechanism is required to realize the bending processing of the metal components. For example, the existing patent with the publication number CN212192073U discloses "a metal raw material bending mechanism for hardware production, which is provided with a cutting knife quick replacement mechanism, which is convenient for timely replacement of wearing parts to ensure the smooth progress of bending operation and improve the stability of use; including a top plate, a hydraulic cylinder, an upper die, a bending protrusion, a lower die, a bending groove, a lower die seat, a cutting knife, a quick-change screw, a cutting knife block, a block slide and a rotary disk, the left and right sides of the lower end of the top plate are respectively connected to the upper ends of the two groups of support legs, the lower end of the oil cylinder seat plate is connected to the middle of the upper end of the top plate, and the lower end of the hydraulic cylinder is connected to the upper end of the oil cylinder seat plate". It can be seen that the application describes a common metal component bending mechanism, which can drive the upper die to move downward by the cylinder to realize the operation of the bending protrusion entering the bending groove, thereby bending the metal component plate placed on the lower die;

[0003] However, when the metal component bending mechanism in the above patent is actually used, there is no structure designed on the lower die to limit the metal component plate, resulting in the metal component plate not being blocked or limited when placed on the top of the lower die, and being prone to lateral shifting during the subsequent downward pressing and bending process, thereby reducing the bending effect and product quality. For this reason, the utility model proposes a metal component bending mechanism. Utility Model Content
