Description

Technical Field

[0001] This utility model relates to the field of terminal block stamping, and in particular to a quick-cutting device for terminal blocks. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. They are a type of connector. When manufacturing terminal blocks using existing technology, it is usually necessary to punch copper, aluminum, copper alloys, or copper-aluminum alloys into conductive sheets of the required shape and size. It is also necessary to punch the connection position with the wire into a ring shape to facilitate the connection between the terminal block and the wire.

[0003] In the existing technology, during the stamping process of terminal blocks, the metal tube is generally positioned and cut by machining. After cutting, the metal tube is processed into terminal blocks by stamping.
