Problems solved by technology

When the diameter of the blade is not less than 3mm, the direct use of silver-copper solder to connect the handle to the blade can meet the shearing force that the milling cutter bears during the milling process, but when the diameter of the blade is less than 3mm, the handle and blade The butt joint area is reduced, and the welding strength of the two cannot meet the shear force requirements of the milling cutter, and the silver-copper soldering sheet can only be used for the butt welding of the handle and the blade

Embodiment

[0018] Please refer to figure 1 , the present embodiment is a low-cost cemented carbide milling cutter 100, which includes a handle 1, a blade 2, the center of the handle 1 is provided with a through hole 3 that penetrates up and down, and the lower end of the blade 2 is inserted into the through hole 3 and Soldered on the inner wall surface of the through hole 3 by silver-copper solder 4 . The silver-copper solder 4 is silver-copper powder and flux.

[0019] The diameter of the handle 1 is 3.075-3.275 mm.

[0020] The diameter of the through hole 3 is 0.6-2.5 mm, preferably 1.0 mm, 1.1 mm, 1.2 mm, 1.5 mm or 2.0 mm.

[0021] In this embodiment, a through hole 3 is set in the handle 1, and then the lower end of the blade 2 is inserted into the through hole 3 and welded together with the inner wall surface of the through hole 3 by silver-copper powder and flux, when the handle 1 and After the entire blade 2 is put into a high temperature of 680-720° C., under the action of fl...

Abstract

The invention discloses a low-cost hard alloy milling cutter. The low-cost hard alloy milling cutter comprises a cutter handle and a cutter edge. A vertically-through through hole is formed in the center in the cutting handle, and the lower end part of the cutter edge is inserted into the through hole and welded to the surface of the inner wall of the through hole through silver-copper powder andsoldering flux. The low-cost hard alloy milling cutter aims at milling cutters with small-diameter cutter edges, the strength requirement can be met, and the production cost can also be effectively reduced.

Description

【Technical field】 [0001] The invention belongs to the technical field of cutter design, in particular to a low-cost hard alloy milling cutter. 【Background technique】 [0002] In the manufacturing industry, turning, milling, and drilling are the processing methods that must be used in the manufacturing process. Therefore, various cutting tools have become necessary tools for the manufacturing industry. The requirements for machining tools vary according to the nature of the processed products. Most of the materials for making cemented carbide tools are tungsten-carbon alloys, which contain a small amount of cobalt. Generally, tungsten-carbon accounts for 93%, and cobalt accounts for 6%. %. [0003] Tungsten has high hardness and high melting point, and is not eroded by air at room temperature. It is mainly used to manufacture filaments, high-speed cutting hard tools, superhard molds, etc. China is the world's largest tungsten reserve country, but its consumption rate is als...
