Problems solved by technology

[0004] As a result, the friction ring or the friction boss generates heat due to friction, and the wear of the wear-resistant ring or the boss will cause the inner saw blade to not be positioned reliably, making the inner saw blade and the outer saw blade loose, so that the inner saw blade and the outer saw blade More reliable positioning and pressing are not obtained, and manufacturing errors are added; rotation jump and swing are unavoidable. The consequence is that when the outer saw blade and the inner saw blade rotate in opposite directions, the friction between the saw blades generates heat, interference and collision. At the same time, It will also cause the materials to be cut to pile up between the outer saw blade and the inner saw blade; cause broken teeth and even cause personal safety hazards and other adverse consequences

Abstract

The invention discloses a manufacturing structure of rotary opposite-cutting saw blades. The manufacturing structure comprises an outer side saw blade and an inner side saw blade. The outer side saw blade consists of an outer side saw blade body and welding cutter teeth; and the inner side saw blade consists of an inner side saw blade body and welding cutter teeth. The manufacturing structure is characterized in that at one side of the working face of the outer side saw blade, the welding cutter teeth are parallel to or lower than the working face and are not allowed to be convex; at one side of the cutting face of the outer side saw blade, the welding cutter teeth are higher than the cutting face to form a secondary cutting blade; at one side of the working face of the inner side saw blade, the welding cutter teeth are parallel to or lower than the working face and are not allowed to be convex; at one side of the cutting face of the inner side saw blade, the welding cutter teeth are higher than the cutting face to form the secondary cutting blade. The manufacturing structure of the rotary opposite-cutting saw blades, provided by the invention, is stable and reliable. The manufacturing structure is applicable to manufacturing a composite saw blade mounted on a cutting machine with double saw blades, and is used for sawing and cutting various materials.

Description

technical field [0001] The invention belongs to the field of rotary sawing tools, and relates to a manufacturing structure of a rotary counter-cut saw blade, which is especially suitable for installation on rotary counter-cut electric circular saws, miter saws, and gasoline-powered chop saws, and is used for metal, stone, and wood , cutting of plastic profiles, plates, etc., and sawing and breaking of various materials at the scene of emergency rescue and disaster relief. Background technique [0002] The rotary counter saw is driven by the concentric output shaft of the transmission device to drive the outer saw blade and the inner saw blade at the same time, one rotates clockwise and the other rotates counterclockwise, thereby generating a counter-rotating cutting motion. Since the sawing directions of the outer saw blade and the inner saw blade are opposite, the outer saw blade and the inner saw blade can balance the reaction force of the material to be cut during cutting...
