Problems solved by technology

[0007] (1) The kerf of sawing is relatively large, and the waste of material is relatively serious;
[0008] (2) When sawing with a band saw blade, the tip of the divided teeth is easy to wear and the service life is short, and the teeth are easily broken or chipped due to the collision of the workpiece during the sawing process;
[0009] (3) The cutting efficiency of this kind of band saw blade is not high

Abstract

The invention discloses a bimetal road grinding band saw blade. The bimetal road grinding band saw blade comprises a saw blade body and a plurality of groups of saw tooth groups arranged on the saw blade body. Each group of saw tooth groups comprises at least one first saw tooth, and the blade end width of each first saw tooth is greater than the width of the saw blade body in the thickness direction of the saw blade, chamfers are arranged on the two sides, in the width direction, of the blade end of each first saw tooth, and at least one side surface of each first saw tooth is an acute-angledinclined surface. The saw blade has a smooth and level saw cutting surface, a small saw kerf and a high advance, the saw cutting margin can be greatly reduced, the saw blade tooth tip wears slowly, and the service life is long.

Description

technical field [0001] The invention relates to a band saw blade, in particular to a bimetal grinding band saw blade. Background technique [0002] When producing saw blades, in order to improve the cutting ability of the saw blade and prevent the saw from being pinched, the width of the cutting edge of the saw blade should be greater than the width of the back of the saw blade. [0003] At present, there are two ways to realize that the width of the cutting edge of the saw blade is greater than the width of the back of the saw blade. One is shunting (also called split teeth), that is, when shunting, there is often one or several fixed teeth in a group of teeth, and the other teeth have a little inclination relative to the fixed teeth, which are staggered left and right; the other is grinding road , that is, the width of the cutting edge of the saw blade is wider than the width of the back of the saw blade after grinding, and the saw road is formed by grinding. The saw roa...
