Problems solved by technology
The punching punch and the punching die are vulnerable parts. After the mold has been used for a period of time, it needs to repair the cutting edge and replace the spare parts. However, when the commonly used stamping die is disassembled, it is necessary to use tools to remove the punching punch from the reverse side of the punch fixing plate. Knocking out is a waste of time, and this method will damage the cutting edge of the punch and seriously affect the daily efficiency. Therefore, it is necessary to design an easy-to-disassemble punch punch and the corresponding puller

Embodiment Construction
[0012] The present invention will be explained below with reference to the drawings.
[0013] The extractor of the punching punch of the present invention includes a handle 1, an extraction rod 2 and an extraction piece 3; the handle 1 is connected to the upper end of the extraction rod 2; the extraction piece 3 is in a straight shape, and two The end is semicircular. When the extractor of the present invention is used, only the extraction piece is clamped in the groove at the upper end of the punching punch and then rotated 90 degrees, the semicircular design of the two ends of the extraction piece 3 ensures that the extraction piece is vertically stuck in the in-line groove The force-receiving area on the inner wall is maximized, and then the punching punch 5 can be pulled out from the punch fixing seat simply and conveniently by applying a vertical upward force.
[0014] To further explain, the handle 1 is provided with a pull ring 4, which is convenient for pulling up manually...

The invention discloses an extraction tool of a punching convex mold. The extraction tool of the punching convex mold comprises a handle, an extraction rod and an extraction piece; the handle is connected to the upper end of the extraction rod; the extraction piece is line-shaped; and the two ends of the extraction piece are semicircular. The extraction tool of the punching convex mold is simple in structure and reasonable in design; and the extraction piece is only clamped in a groove at the upper end of the punching convex mold, then rotates by 90 degrees, and is clamped on the inner wall of the groove, so that the punching convex mold can be simply and conveniently extracted out from a convex mold fixing base through upwards vertically exerting strength, the convex mold is not damaged, the disassembly is convenient, the working efficiency is greatly improved, and the extraction tool of the punching convex mold can be promoted in a wide range.
Description
Technical field [0001] The invention belongs to the technical field of stamping dies, and in particular relates to a punching punch extractor. Background technique [0002] The punching die mainly includes a punching punch and a punching die that cooperate with each other. The punching punch is assembled in the punch fixing plate, and the punching die is assembled in the die fixing plate. Punching punches and punching dies are vulnerable parts. After the mold has been used for a period of time, it is necessary to repair the edge of the mold and replace the spare parts. However, when the commonly used punching dies are disassembled, the punching punch needs to be removed from the opposite side of the punch fixing plate. Knock it out is a waste of time, and this method will damage the edge of the punch and seriously affect the daily efficiency. Therefore, it is necessary to design a punching punch that is easy to disassemble and the corresponding extractor. Summary of the inventio...
