Abstract

The invention discloses a shearing knife with a bionic curved surface and belongs to the technical field of metal cutting. The shearing knife with the bionic curved surface is composed of a knife matrix, a knife back, a transition segment and a knife point; and the transition segment is composed of bionic semi-cylinders and a triangular prism. The knife matrix is of a cuboid structure and serves as the back side of the whole bionic shearing knife to bear the knife back, the transition segment and the knife point; the knife back is a cuboid, and is located on the surface of the knife matrix, and the bottom face and the two side faces of the knife back coincide with the bottom face and the side faces of the knife matrix correspondingly; the transition segment is a combination of the bionic semi-cylinders and the triangular prism structure; and the bionic semi-cylinders are closely arranged in an array manner in the long side direction of the shearing knife. The bottom of the triangular prism coincides with the top end of the rear segment of the knife, and the length and the width of the bottom face of the triangular prism are equal to those of the rear segment of the knife; the upper portions of the bionic semi-cylinders coincide with the triangular prism; and the knife point is a bionic curved surface structure. By means of the shearing knife with the bionic curved surface, the shearing capacity of blades of a shearing machine can be improved, the blade utilizing time is prolonged, the work efficiency is improved, and cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of metal cutting, and in particular relates to a bionic curved surface shearing knife. Background technique [0002] The shearing machine is the main equipment in the cutting device of the modern factory, and the gantry shearing machine is mainly used in scrap steel cutting and large-size cutting. In the iron and steel industry, shearing machines are used more and more, and more are used for heavy cutting. [0003] The blade of the shearing machine is the most critical part of the shearing machine. Its performance is related to the use and efficiency of the entire equipment, and is closely related to production and processing and economic benefits. At present, factories and scrap steel processing cannot replace a large number of blades every year. Not only the cost of blades increases, but also the production time is limited, which greatly reduces the output value and affects the entire processing efficienc...
