The worker holds the disc shell, places the edge of the disc shell on the product positioning table, and the stamping head penetrates into the stamping clearance slot to stamp an edge gap on the edge of the disc shell.

[0007] The guide groove is equal in width to the cavity, the stamping clearance groove is narrower than the guide groove, the top of the cavity is higher than the stamping clearance groove, and the top of the movable block is located in the top of the cavity. When the guide convex part does not enter the guide groove, the first inclined surface of the movable block is pressed against the left side wall of the stamping clearance groove under the elastic force of the reset spring. When the guide convex part enters the guide groove, the second inclined surface drives the movable block to move left, and the reset spring is compressed.

[0008] The lower die comprises an upper part, a middle main body and a bottom plate, the guide groove and the stamping clearance groove are arranged on the upper part, the top of the cavity is arranged on the upper part, the main body of the cavity is arranged on the middle main body, and the discharge port is arranged on the middle main body.

[0009] As an option, the upper part and the middle main body are welded, and the middle main body and the bottom plate are welded.

[0010] The left side of the movable block is provided with a spring positioning hole, the left side of the middle main body is provided with a threaded hole, one end of the reset spring is positioned in the spring positioning hole, the other end of the reset spring is positioned in the threaded hole, and a positioning bolt is screwed in the threaded hole.

[0011] The utility model provides a disc shell edge gap stamping die which can automatically discharge waste materials, so that the production can be carried out smoothly. BRIEF DESCRIPTION OF DRAWINGS
