Problems solved by technology
[0002] Cemented carbide has the advantages of high hardness and wear resistance, and is widely used in lathe processing tools. Generally, the blade and the tool holder are integrated. During the machining process, it is necessary to use a milling cutter to mill out the end faces of different workpieces. Due to long-term wear, high temperature, etc., the service life of the blade is very short, so the blade must be scrapped together with the blade, resulting in waste
And during the processing, the friction between the tool and the workpiece will generate a lot of heat, which further accelerates the scrapping of the blade and affects the processing accuracy

Embodiment Construction
[0013] The present invention will be described in further detail in conjunction with the accompanying drawings and specific embodiments.
[0014] Such as figure 1 As shown, the cemented carbide cutting tool of the present invention comprises a cemented carbide blade, a cemented carbide knife holder 2 and a cemented carbide knife groove 4, wherein the cemented carbide knife holder 2 and the cemented carbide knife groove 4 are integrally designed, and the hard metal The cemented carbide sipe 4 is located at the end of the cemented carbide knife bar 2, the shape of the cemented carbide sipe 4 matches the shape of the cemented carbide blade, and the edge of the cemented carbide blade is exposed outside the edge of the cemented carbide sipe 4 . A threaded hole 3 is provided in the cemented carbide sipe 4, and a through hole is also arranged on the cemented carbide blade, and the cemented carbide blade is fastened in the cemented carbide sipe 4 by a screw nut. The tungsten carbide...

Abstract
The invention discloses a hard alloy tool, which comprises a hard alloy blade, a hard alloy tool shank and a hard alloy cutter groove, wherein the hard alloy tool shank and the hard alloy cutter groove are in an integral design; the hard alloy cutter groove is formed in the end part of the hard alloy tool shank; the hard alloy cutter groove and the hard alloy blade are fixedly connected with each other through screw rods and nuts and are coincided with each other in shape; the knife edge of the hard alloy blade after the hard alloy tool is mounted is exposed out of the edge of the hard alloy cutter groove; and a spiral cooling channel is also formed in the hard alloy tool shank, so as to be convenient to cool. According to the hard alloy tool, the blade can be exchanged after being scrapped, so that waste of the tool shank is avoided; meanwhile, the cooling channel plays a certain cooling role in the machining process; reduction of the temperature of the blade is facilitated; and the cutting speed and the machining accuracy are improved.
Description
technical field [0001] The invention relates to a cemented carbide cutting tool, which belongs to the technical field of mechanical processing. Background technique [0002] Cemented carbide has the advantages of high hardness and wear resistance, and is widely used in lathe processing tools. Generally, the blade and the tool holder are integrated. During the machining process, it is necessary to use a milling cutter to mill out the end faces of different workpieces. Due to long-term wear, high temperature, etc., the service life of the blade is very short due to the inclined surface, groove or step surface, so it will be scrapped together with the tool holder, resulting in waste. Moreover, during the machining process, the friction between the tool and the workpiece will generate a large amount of heat, which further accelerates the scrapping of the blade and affects the machining accuracy. Contents of the invention [0003] The object of the present invention is to prov...
