The invention is characterized in that: the diameter of the shear blade is calculated through a formula, so that the selection of the shear blade is more reasonable, the shearing efficiency is improved, the shearing quality is ensured, and the service life of the shear blade is prolonged.)

1. The utility model provides a slitting machine disc shear blade structure which characterized in that: including upper and lower complex shear blade (1) and lower shear blade (2) about the structure is the same, upper shear blade (1) and lower shear blade (2) relative rotation, panel (3) get into the shear blade that upper shear blade (1) and lower shear blade (2) formed, cut off by upper shear blade (1) and lower shear blade (2) cooperation, the diameter of upper shear blade (1) and lower shear blade (2) is according to pressing

Technical Field

The invention relates to the field of steel rolling mechanical equipment, in particular to a disc shear blade structure of a slitting machine.

Background

The diameter of the disc shear blade of the existing slitting machine is selected completely according to experience and reference, the diameter is sometimes larger and sometimes smaller, the shearing speed is seriously influenced, the abrasion of the shear blade is also increased, and many unreasonable phenomena are caused.

Disclosure of Invention

The invention aims to overcome the defects and provide a disc shearing blade structure of a slitting machine.

The technical scheme adopted by the invention for realizing the purpose is as follows: the utility model provides a slitting machine disc shear blade structure which characterized in that: the cutting device comprises an upper shear blade and a lower shear blade which are in same structure and are matched up and down, wherein the upper shear blade and the lower shear blade rotate relatively, a plate enters a shear cutting edge formed by the upper shear blade and the lower shear blade and is cut off by the upper shear blade and the lower shear blade in a matching way, and the diameters of the upper shear blade and the lower shear blade are determined according to the diameter

Selecting, wherein:

in order to provide a bite angle,

for the relative cut-in depth factor,

is the thickness of the plate and D is the diameter of the cutting edge.

The invention is characterized in that: the diameter of the shear blade is calculated through a formula, so that the selection of the shear blade is more reasonable, the shearing efficiency is improved, the shearing quality is ensured, and the service life of the shear blade is prolonged.
