Cutter body for cutting alloy strip and strip cutting device

According to the cutter body for cutting the alloy strip and the strip cutting device, the whole cutter body is columnar, the cutting end face is arranged on the lower side of the cutter body, and the cutting end face is arranged to be an inclined face with an inclined angle relative to the horizontal plane; due to the fact that the cutting end face is arranged to be the inclined face with the inclined angle relative to the horizontal plane, when the cutter body makes contact with the amorphous strip through the cutting end face, the cutter body can make contact with one side edge of the amorphous strip firstly, stress is concentrated to enable the amorphous strip to be fractured, local faults are caused, and the amorphous strip is pushed along with falling of the cutter body. And the cutter body is guided along the edges of the two sides of the cutting end face, so that the two ends of the strip are cut off by the fault to be smoothly divided into three sections. 本实用新型提供的用于合金带材切割的刀体及带材切割装置，其整体呈柱状，其下侧设置切割端面，所
