Description

Hard alloy tool bit

Technical Field

The utility model relates to the technical field of hard alloy, in particular to a hard alloy cutter head.

Background

Cemented carbide is an alloy material made from a hard compound of refractory metals and a binder metal by a powder metallurgy process. The hard alloy has a series of excellent performances of high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance and the like, particularly high hardness and wear resistance, basically keeps unchanged even at the temperature of 500 ℃, and still has high hardness at the temperature of 1000 ℃. Cemented carbide is widely used as a tool material, such as turning tools, milling cutters, planing tools, drill bits, boring tools and the like, for cutting cast iron, nonferrous metals, plastics, chemical fibers, graphite, glass, stone and common steel, and also for cutting refractory steel, stainless steel, high manganese steel, tool steel and other materials which are difficult to process.

The hard alloy cutter head is widely applied to production equipment as an application of hard alloy. The cutter head is provided with a groove directly on the cutter bar, then the blade is arranged in the groove and fixed through a fastening means, namely the blade is in direct contact with the cutter bar, the blade generates a large amount of heat in the using process, and the cutter bar made of hard alloy is easy to crack in a high-temperature state, so that the using effect is influenced.

Disclosure of Invention

The utility model aims to provide a hard alloy cutter head, which avoids the direct contact between a cutter point and a cutter rod, thereby reducing the risk of damage to the cutter rod.

In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a carbide tool bit, a serial communication port, including cutter arbor, knife tip and knife rest, the tip of cutter arbor is to its axis direction sunken first depressed part and the second depressed part of formation, the knife rest is V type structure, including first installation department and second installation department, first installation department is located in the first depressed part, the second installation department is located in the second depressed part, first installation department and second installation department all through the screw with the cutter arbor is connected, the knife tip is located the up end of knife rest, wherein the knife tip is V type structure.

The utility model further provides that the tool tip is welded at the upper end of the tool rest, and part of the tool tip extends out of the tool rest.

The utility model further provides that the first mounting part and the second mounting part are provided with backing plates.

The utility model has the beneficial effects that: according to the utility model, the cutter rest is arranged, the cutter point and the cutter bar are connected through the cutter rest, the direct contact between the cutter point and the cutter bar is avoided, the cutter rest is used as an intermediate piece, the heat generated when the cutter point works is reduced and transferred to the cutter bar, and thus the risk of cutter bar damage is reduced.
