Problems solved by technology

Traditional stamping dies tend to generate large stress during the stamping process, so it is easy to affect the service life of the stamped plate. Therefore, in the existing design, some large plates are stamped in stages to reduce the impact of stamping stress on the workpiece.

Abstract

The invention relates to a graded die. The graded die comprises a first-stage stamping part and a second-stage stamping part. The first-stage stamping part is located inside the second-stage stampingpart, a positioning rod is arranged on the outer surface of the lower end of the first-stage stamping part, the positioning rod freely slides in the vertical direction of the first-stage stamping part, and the upper end of the first-stage stamping part is fixedly connected with an upper plate piece. A connecting plate piece is fixedly connected to the position, close to the upper end, of the outersurface of the upper plate piece, a stamping mechanism is fixedly connected to the connecting plate piece, the stamping mechanism drives the first-stage stamping part and the second-stage stamping part to move downwards, and the lower end face of the second-stage stamping part tightly presses the surface of a to-be-stamped workpiece in a covering mode. The staged die is simple in structure and convenient to operate; the stamping precision is improved, the second-stage stamping part is easy to make, dismount and mount, damage caused by direct stamping of the first-stage stamping part to the surface of a workpiece can be effectively prevented, burrs generated by punching are lessened, and application and popularization are facilitated.

Description

technical field [0001] The invention belongs to the technical field of stamping dies, in particular to a hierarchical stamping die. Background technique [0002] Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength. Stamping can produce workpieces with ribs, ribs, undulations or flanges that are difficult to manufacture by other methods to increase their rigidity. Traditional stamping dies tend to generate large stress during the stamping process, so it is easy to affect the service life of the stamped plate. Therefore, in the existing design, some large plates are stamped in stages to reduce the impact of stamping stress on the workpiece. . Contents of the invention ...
