Technical Field

[0001] The utility model relates to the technical field of pressure riveting, in particular to a pressure riveting die. Background Art

[0002] In the process of using the riveting mold, it is usually necessary to use the riveting copper column. The riveting copper column is a common fastener and is widely used in various mechanical and electrical equipment. Its main features are high strength, good conductivity and corrosion resistance. Therefore, it is very popular in applications that require fastening and conductivity.

[0003] When using a riveted copper column, it needs to be fixed on a substrate, and then another plate or component is placed on the plane of the riveted copper column and pressed using a riveting machine. When the riveted copper column is pressed, its conical part will expand and be fixed on the substrate, while firmly connecting the plates or components together. However, when using a riveting die to fix the riveted copper column to the substrate, the powerful impact of the riveting machine not only makes the connection between the riveted copper column and the substrate more firmly, but also fastens the bottom end of the riveted copper column to the notch of the lower die. When taking the connected riveted copper column and the substrate, it is necessary to use a large force to buckle the riveted copper column out of the notch of the lower die, which is time-consuming and labor-intensive, and the taking process is not convenient.

At this time, the bottom ends of the riveted copper pillars 11 will be firmly stuck in the slots 13 under the strong pressure of the riveting mechanism. By using the principle of leverage, the support rods 17 are pressed, and the movable pillars 14 are pushed upward, so that the riveted copper pillars 11 stuck in the slots 13 can be pushed out, reducing the manual triggering of the riveted copper pillars 11, saving time and effort, and improving the installation efficiency of the riveted copper pillars 11.
