Abstract

The invention discloses a stamping, bending and punching die, which is characterized in that it comprises a fixed upper die and a moving lower die, a fixed plate is arranged under the upper die, and a vertical sliding plate is arranged to slide vertically on the fixed plate. The lower part of the vertical slide is provided with a driving cam, the upper part of the vertical slide is horizontally slid and provided with a horizontal slide, the left end of the horizontal slide is vertically provided with a left punch, the top of the vertical slide is vertically provided with an upper punch, and the lower die is provided with a through hole. , the support column is provided with a stamping spring, the upper end of the stamping spring is connected to the lower die, the lower part of the vertical slide is provided with a bent bar, the upper end of the bent bar is provided with a bar-shaped hole, and the horizontal slide is provided with a limiter for passing through the bar-shaped hole. As for the positioning post, the lower end of the curved rod is provided with a first roller and a second roller which are in contact with the driving cam, and a compression spring is arranged between the driving cam and the curved rod. The invention provides a stamping, bending and punching die, which realizes one-time bending and punching operations on U-shaped connectors.

Description

technical field [0001] The invention relates to the stamping field, in particular to a stamping, bending and punching die. Background technique [0002] In cold stamping, the stamping die processes the material (metal or non-metal) into parts or semi-finished products. During stamping, the mold installed on the press is used to apply pressure to the material to cause separation or plastic deformation to obtain the required parts. Usually a pair of stamping dies can realize one-time surface forming, cutting, stretching, bending, punching and other operations on the material. [0003] For example, the Chinese utility model patent with the existing publication number CN 207971236 U discloses "A Bending Die for Plates", which includes a workbench and a hydraulic cylinder. The bottom of the workbench is provided with supporting legs, and the right end of the workbench A support plate is hinged, and the support plate and the workbench are set at an obtuse angle. An oil cylinder A...
