Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for pressing materials in different regions. Background Art

[0002] Stamping dies are special process equipment used to process materials into parts during cold stamping. Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts.

[0003] At present, a stamping die plate-type pressing mechanism disclosed in the Chinese patent announcement with announcement number CN204974990U includes: an upper die seat and a pressing mounting plate; a stepped groove is provided at the center of the upper die seat, and a mounting seat is provided on the stepped groove; the pressing mounting plate is fixedly connected to the mounting seat; a plurality of nitrogen cylinders are provided on the pressing mounting plate, a fixed seat is provided between the pressing mounting plate and the nitrogen cylinder, and an air pipe is connected between the nitrogen cylinders; a pressure regulating valve is also provided on the pressing mounting plate, and the two ends of the pressure regulating valve are respectively connected to the air pipe. The stamping die plate-type pressing mechanism of the utility model changes the fixing method of the nitrogen cylinder from being directly fixed on the upper die seat to being fixed on the movable pressing mounting plate, and the stamping die plate-type pressing mechanism has the advantages of simple structure, compactness, good safety and stability, and reduces the casting cost, saves the later maintenance cost, effectively reduces the pressure debugging, inflation, error, and maintenance, assembly and debugging labor intensity of the nitrogen cylinder, and shortens the mold development cycle.

[0004] However, in the traditional forming mold, there is only one pressing core, and pressing core one and pressing core two are a whole. Because this part has special requirements for pressing in the pressing core one area, the material sheet needs to be pressed here and not move. If one pressing core is used as a whole, since there are more product shapes in the pressing core two area, a larger forming force is required, and a 360T nitrogen cylinder is needed to achieve the pressing requirements. Therefore, we proposed a stamping die with divided regional pressing to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a stamping die for pressing materials in different areas.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0013] Beneficial effects of the utility model:

[0014] 1. After the pressing core 1 and the pressing core 2 are separated, only one part of the pressing core needs to be pierced. Since the shape of the pressing core 1 area is gentle, only 50T of pressing force is needed for the pressing core 1 to meet the pressing requirements. The pressing core 2 does not need to be pierced when pressing, so only 100T of pressing force is needed. A total of 150T is needed to meet the pressing requirements, saving a lot of nitrogen cylinder costs;

[0015] 2. By providing a connecting mechanism, when the upper mold body is installed on the lower mold body, the connecting seat is rotated so that the mounting hole rotates one side of the mounting thread groove, and the fixing screw is rotated so that the fixing screw can be screwed into the thread groove, thereby achieving the purpose of fixed connection between the upper mold body and the lower mold body.
