Self-rotating annular shearing device

Abstract

The invention relates to a shearing device, in particular to a self-rotating annular shearing device. The self-rotating annular shearing device comprises a bottom plate and an upper plate matched withthe bottom plate. A rotating device used for enabling a workpiece to automatically rotate is arranged on the bottom plate, and a shearing device used for realizing annular shearing is arranged on theupper plate. A lifting mechanism used for enabling the shearing device to properly lift up and lift down is arranged between the bottom plate and the upper plate. An inner gear ring and a gear are used as an automatic rotating base of the workpiece, so that the stablilizing effect is good. The position on the bottom plate can be properly adjusted, so that the flexibility is high. A shearing screwand a push block are matched to realize the annular shearing with an adjustable shearing diameter. Compared with a ring cutting machine on the market, the self-rotating annular shearing device has the advantages of being convenient to use and reducing production cost.

Description

technical field [0001] The invention relates to a shearing device, in particular to a self-rotating annular shearing device. Background technique [0002] Shearing machines are mostly straight-line shearing machines, which are mainly used to cut the straight edges of metal sheets of various sizes, and are involved in rolling steel, automobiles, airplanes, ships, etc., and there are many types of shearing machines, but in When circular cutting is required, existing shearing machines are more difficult to realize, and when the diameter of the shearing workpiece changes, less can be used flexibly, so there is a large gap in the market. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a self-rotating annular shearing device. [0004] A self-rotating annular shearing device, comprising a base plate and an upper plate matched with the base plate, the base plate is provided with a rotating device for automatically rotating t...
