Abstract

The invention provides a cutter head for being welded to a tooth support of a band saw blade. The cross section of the cutter head is surrounded by a first straight line segment, a second straight line segment, a first arc segment which is in contact with the tooth support and a second arc segment which is arranged relative to the first arc segment; one end of the first arc segment is connected with one end of the first straight line segment, and the other end of the first arc segment is connected with one end of the second straight line segment; one end of the second arc segment is connectedwith the other end of the first straight line segment, and the other end of the second arc segment is connected with the other end of the second straight line segment; and the second arc segment is protruded to one side away from the first arc segment. According to the cutter head disclosed by the invention, the shape of the cutter head for welding is changed, so that the grinding allowance of a hard alloy cutter head is reduced, the welding strength is improved, the grinding efficiency is improved, the durability of a diamond grinding wheel for grinding hard alloy is strengthened, and the purpose of reducing cost is achieved.

Description

technical field [0001] The invention relates to a sawing metal cutter, in particular to a cemented carbide cutter head, a band saw blade containing the cutter head and an electrode matched with the cutter head. The invention is mainly applied to hard alloy band saw blades. Background technique [0002] At present, during the sawing process of cemented carbide band saw blades, the amount of grinding must be considered. The traditional welding method adopts brazing, and the welding strength needs to be considered when designing the size of the cutter head. Therefore, in general, the size design of the cutter head is too large, which is not good for grinding. With the development of welding technology, it is now possible to perform resistance welding on the surface of cemented carbide with nickel plating and cobalt plating, and the welding quality has been further developed. In order to be more conducive to the grinding of cemented carbide, the design of the cemented carbide ...
