Hard alloy cutter with internal spiral cooling liquid hole and production equipment thereof

Abstract

The invention relates to the technical field of hard alloy cutters, in particular to a hard alloy cutter with an internal spiral cooling liquid hole and production equipment thereof. The production equipment comprises a machining table and further comprises a material supplying mechanism, an extrusion mold mechanism and a cooling discharging mechanism; the extrusion mold mechanism comprises a heating feeding sleeve and a forming mold; the heating feeding sleeve comprises a feeding inlet and a discharging outlet, and the forming mold is installed in the position, located at the discharging outlet, of the heating feeding sleeve; the material supplying mechanism comprises a material supplying bin, the material supplying bin is provided with a material guide opening, and the interior of the material supplying bin is provided with an extrusion head; the cooling discharging mechanism comprises a rotary cooling assembly and a discharging table; and the rotary cooling assembly comprises a cooling bin, the cooling bin is provided with a round through hole penetrating through two surfaces, and the interior of the round through hole is provided with cooling spray heads. According to the technical scheme, through the extrusion forming mold, the size stability of a hard alloy round bar product with the internal spiral hole can be improved, the appearance is attractive, the percent of pass is high, in addition, cooling can be automatically conducted, and the production quality is improved.

Description

technical field [0001] The invention relates to the technical field of cemented carbide cutting tools, in particular to a cemented carbide cutting tool with an inner spiral cooling liquid hole and production equipment thereof. Background technique [0002] The cemented carbide rod with internal spiral cooling hole is a representative product of ultra-fine cemented carbide high-tech. Drills, end mills, taps, reamers, etc. produced from this bar have the advantages of good cooling effect, high chip removal efficiency, good surface finish, and long tool life. Traditional processing cutting tools are used as industrial processing tools. The more commonly used workpieces are widely used in processing lathes. Since lathe processing generally processes metal workpieces, metal workpieces are prone to overheating during processing, which will not only cause damage to the processed workpieces, but also the processed products. There are also certain flaws. At present, the equipment fo...
