Abstract

The invention discloses a rotary type saw blade protective mechanism which comprises a clamping sleeve arranged on the two sides of a saw blade, wherein a cutting hole is formed in the clamping sleeve; the clamping sleeve is driven by a rotary motor, can rotate with a spindle of the saw blade as a center of a circle and is composed of a front clamping part and a back clamping part; the front clamping part and the back clamping part are both circular; the saw blade is buckled between the front clamping part and the back clamping part; and the diameter of the outer edge of each of the front clamping part and the back clamping part is a little smaller than that of the saw blade. The rotary type saw blade protective mechanism is used for strengthening the rigidity of the saw blade when the saw blade cuts a workpiece and particularly begins to cut the workpiece so as to reduce the deformation quantity of the saw blade, improve the cutting quality of the saw blade and prolong the service life of the saw blade.

Description

technical field [0001] The invention relates to a protection device for a saw blade of a circular saw machine, in particular to a mechanism for a rotary saw blade protection. Background technique [0002] Circular saws use circular saw blades to cut metal workpieces. Due to the large diameter and thickness ratio of circular saw blades, and they are only clamped on the main shaft with two rings at the center, the rigidity is poor and the working stability is not stable. High, because the outer circle of the workpiece is not smooth, at the beginning of cutting, the force on both sides of the saw teeth is uneven, and it is easy to deviate to one side, especially when the saw teeth are blunted, the resistance increases, and the circular saw blade is more likely to be deformed, thus affecting the product accuracy. , and even the circular saw blade breaks. At present, it is common to add several pairs of fixed clamping parts in the edge area of ​​the circular saw blade. When the ...
