Abstract

The invention discloses a side grinding structure and method of hard alloy band saw blade bits. The side grinding structure comprises a saw blade which is fed at a constant speed, hard alloy bits are welded to the tooth tips of the saw blade, and the two sides of the saw blade are each provided with a grinding wheel used for grinding the side faces of the hard alloy bits. Each grinding wheel is a frustum-shaped grinding wheel with a large-diameter end and a small-diameter end, wherein the saw blade starts from the small-diameter end of the grinding wheel and is kept in contact with the outer circle grinding surface of the grinding wheel until the saw blade disengages contact with the outer circle grinding surface of the grinding wheel from the large-diameter end of the grinding wheel, a main shaft of the grinding wheel is arranged at an inclination angle A relative to the feeding direction of the saw blade, in the saw blade feeding process, the side faces of the multiple hard alloy tool bits on the saw blade make contact with the outer circle grinding face of the grinding wheel at the same time, and a grinding interval with the width of 3.5-4.5 mm is formed on the outer circle grinding face of the grinding wheel. The side faces of the hard alloy bits obtain a good plane after being ground by the grinding intervals.

Description

technical field [0001] The invention relates to a cemented carbide band saw blade, in particular to a structure and method for side grinding the cutter head of a cemented carbide band saw blade. Background technique [0002] Carbide band saw blades are widely used in sawing difficult-to-cut metal materials, such as die steel, stainless steel, surface hardened steel, titanium and titanium alloys, nickel-based alloys, high-temperature alloys, etc., and are widely used in high-speed sawing of aluminum alloys, Hardwood material. At present, the cemented carbide band saw blade products used in the market mainly fall into two categories: split-toothed and non-toothed. These two kinds of hard alloy band saw blade products are made of high-quality spring steel as the back material, and cemented carbide particles are welded at the tip of the tooth as the hard alloy blade, and the hard alloy blade is ground into sharp teeth by diamond wheels. The spring steel back material can ensur...
