Embodiment Construction

[0011] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0012] Such as figure 1 , figure 2 The shown cemented carbide turning tool includes a tool bar 2 and a tool head 1 connected to one end of the tool bar 2, and the tool bar 2 and the tool head 1 are integrally formed. Therefore, the formation of installation errors is completely eliminated, and the error impact of the tool on the processed parts is reduced to the minimum.

[0013] The cross-section of the knife rod part 2 is a square, and the width of each side is a. The cutter head 1 is inclined to an included angle of the cross-section of the cutter bar part 2, and the cutting edge section 1-1 of the cutter head part 1 is formed at the most pointed point, and the most pointed part of the cutting edge section 1-1 protrudes from the cutter bar part The side surface of the cutting edge section 1-1 is inclined to a circular arc concave between the...

Abstract

The invention discloses a hard-alloy turning tool and relates to the technical field of hard-alloy tool machining machinery. The hard-alloy turning tool comprises a tool bar part and a tool head part connected with one end of the tool bar part. The tool bar part and the tool head part are integrally formed. The cross section of the tool bar part is square. The tool head part inclines towards the cross section of the tool bar part by an included angle, and a cutting edge section of the tool head part is formed when the tool head part inclines to the sharpest position. The sharpest position of the cutting edge section protrudes from the side face of the tool bar part. The cutting edge section is recessed in the circular-arc shape before inclining to the sharpest position. Compared with the prior art, through the hard-alloy turning tool, the problem that the machining precision of an existing hard-alloy turning tool is not high enough can be solved.

Description

technical field [0001] The invention relates to the technical field of cemented carbide tool processing machinery, in particular to a turning tool made of cemented carbide. Background technique [0002] Existing turning tools made of cemented carbide generally include a tool bar and a turning tool head. The tool bar and the turning tool head are two parts that are independently processed. The turning tool head is processed with hard alloy. , The turning head is installed on the tool bar, and the blade part of the turning tool head is generally wider than the width of the tool bar, so as to facilitate rough turning or fine turning of the workpiece. However, there will always be installation errors in the installation of the turning head and the tool holder, which will affect the machining accuracy of the finish car, and the cutting edge of the turning head is difficult to process and has a single shape, so it is difficult to process parts with complex shapes. Contents of th...
