Special variable-edge type indexable turning tool blade for steel

Abstract

The invention discloses a special variable-edge type indexable turning tool blade for steel. The blade comprises a blade main body, an upper surface, a lower surface and a side surface, the blade main body is a convex hexagonal cylindrical body, the blade main body is provided with three groups of vertex angles, the vertex angles are 80 degrees, the vertex angles of the blade main body are provided with cutting edges, the blade main body is provided with a front blade face, a platform is arranged on the blade main body, a chip containing groove is arranged on the blade main body, a boss and an inclined face are arranged on the blade main body, an obtuse angle is arranged between every two adjacent sets of vertex angles of the blade main body, and a side groove is formed in the blade main body. When the turning tool blade is used, the turning tool blade can be suitable for cutting parameters in a wide range by changing the edge width and the associated matching structure of double front angles, chip removal is smooth, the problems that a tool is fast in abrasion, prone to breakage, prone to heat dissipation, difficult in chip breaking and the like are solved, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of cutting blade equipment, in particular to a variable edge type indexable turning blade for steel materials. Background technique [0002] Turning blades are tools used to cut workpieces during lathe processing, among which steel turning blades are one of the most widely used cutting tools in turning processing. Now steel processing pursues high efficiency, cutting parameters are relatively high, and processed products are becoming more and more Diversification, not only to improve the dimensional accuracy and geometric tolerance accuracy of product processing, but also the quality requirements for the surface of the processed workpiece are getting higher and higher, the requirements for turning inserts are also getting higher and higher, and high-speed processing of steel is gradually forming a trend. [0003] Among them, the chip breaker of the turning blade has a more important influence on the turning ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of variable edge type indexable turning insert specially for steel materials. By changing the associated matching structure of the edge width and double rake angle, the turning insert can be applied to a wide range of cutting parameters, and the chip removal is smooth, avoiding Solve the problems of fast tool wear, easy tool breakage, heat dissipation, difficult chip breaking, etc., in order to solve the problems raised in the above background technology
