The invention provides a sharp-corner forming cutter which comprises a cutter bar and a cutter head formed at one end of the cutter bar, wherein the cutter head is provided with a first cutter tooth, a second cutter tooth and a third cutter tooth, the first cutter tooth is sequentially provided with a first arc-shaped cutting edge and a first axial cutting edge which protrude outwards from the end part of the cutter head, the second cutter tooth is sequentially provided with a second vertical axial cutting edge, a second arc-shaped cutting edge which protrudes outwards and a second vertical radial cutting edge from the end part of the cutter head, and the third cutter tooth is provided with a third axial cutting edge. According to the invention, through the matching of the first cutter tooth, the second cutter tooth and the third cutter tooth, the sectional processing and the forming are carried out simultaneously, and the high-efficiency and accurate processing is realized; the cutting edges of the first cutter teeth and the second cutter teeth for processing sharp corners are transited through arc-shaped cutting edges, so that the cutter is firm and durable and is not easy to wear or crack.
Description
Technical Field
The invention relates to the field of machining tools, in particular to a sharp corner forming tool.
Background
A tool is a tool used for cutting machining in machine manufacturing. The forming turning tool is a special tool for processing the forming surface of the revolving body. The forming lathe tool is used for processing, the forming surface can be cut out by only one cutting stroke, the operation is simple, the production efficiency is high, the precision of the forming surface is independent of the operation level of workers, and the manufacturing precision of the cutting edge of the tool is mainly determined. For the forming processing of the groove, the tool nose is passivated usually in order to prolong the service life of the tool edge, and the tool nose is prevented from cracking and damaging in the milling process, but only some grooves which have no special requirement on the sharpness of corner positions can be processed, and for some grooves which require that the corners of the groove bottom surface and the groove wall are sharp corners instead of round corners, the requirement cannot be met, because the sharp corner tool edges on two sides are easy to wear or crack when being directly processed by a processing tool which is consistent with the cross section shape of the groove.
Disclosure of Invention
In order to solve the problems, the invention provides a sharp corner forming cutter which is firm, durable, high in precision and efficient.
The invention provides a sharp-corner forming cutter which comprises a cutter bar and a cutter head formed at one end of the cutter bar, wherein the cutter head is provided with a first cutter tooth, a second cutter tooth and a third cutter tooth, the first cutter tooth is sequentially provided with a first arc-shaped cutting edge and a first axial cutting edge which are protruded outwards from the end part of the cutter head, the second cutter tooth is sequentially provided with a second axial cutting edge which is vertical in the axial direction, a second arc-shaped cutting edge which is protruded outwards and a second radial cutting edge which is vertical in the radial direction from the end part of the cutter head, and the third cutter tooth is provided with a third axial cutting edge.
In one or more embodiments of the present invention, the first cutter tooth, the second cutter tooth, and the third cutter tooth include two cutter teeth, and all of the two cutter teeth are symmetrically disposed.
In one or more embodiments of the present invention, the third blade tooth is disposed between the first blade tooth and the second blade tooth.
In one or more embodiments of the present invention, flutes are disposed at axially spaced positions of the first cutter tooth, the second cutter tooth, and the third cutter tooth.
The invention has the beneficial effects that: the sharp-corner forming cutter provided by the invention is provided with a first cutter tooth, a second cutter tooth and a third cutter tooth, wherein the first cutter tooth is sequentially provided with a first arc-shaped cutting edge and a first axial cutting edge which are protruded outwards from the end part of a cutter head, the second cutter tooth is sequentially provided with a second vertical axial cutting edge, a second arc-shaped cutting edge which is protruded outwards and a second vertical radial cutting edge from the end part of the cutter head, and the third cutter tooth is provided with a third axial cutting edge. The first cutter tooth and the second cutter tooth are respectively used for cutting partial bottom surfaces and one groove wall of the grooves and sharp corners formed by the groove walls and the bottom surfaces, and the third cutter tooth is used for milling a plane parallel to the bottom surfaces of the grooves. . Through the matching of the first cutter tooth, the second cutter tooth and the third cutter tooth, the sectional processing and the forming are carried out simultaneously, and the efficiency and the accuracy are high; the cutting edges of the first cutter teeth and the second cutter teeth for processing sharp corners are transited through arc-shaped cutting edges, so that the cutter is firm and durable and is not easy to wear or crack.
