Problems solved by technology

[0005] In order to overcome the deficiencies of the existing technical structure, according to aluminum alloy, hardened steel, etc., it is difficult to break chips during processing, and it is very easy to generate continuous chips, and the continuous chips are easy to scratch the surface of the workpiece or chip the tool, and the processing efficiency is low. Problem, the present invention provides a superhard insert with a chip breaker

Embodiment 1

[0021] Embodiment 1: as figure 1 As shown, the shape of the blade is rectangular, which is a D-type blade in the ISO standard. The cutter head 2 is welded on the base body 1 by brazing. On the surface of the cutter head 2, there is a cutting edge 4 at the corner of the rectangle, and the concave part behind the cutting edge 4 is a chip breaker 3. The chip breaker 3 is processed on the surface of the cutter head 2 by laser engraving.

[0022] Such as figure 2 The enlargement of the figure shows that the chip breaker angle α formed between the cutting edge 4 and the chip breaker 3 ranges from 15° to 25°.

Embodiment 2

[0023] Embodiment 2: as image 3 As shown, the shape of the blade is polygonal, which is an H-type blade in the ISO standard. The cutter head 2 is welded on the base body 1 by brazing. On the surface of the cutter head 2, cutting edges 4 are arranged on the edges and corners, and the concave part behind the cutting edge 4 is a chip breaker 3. The chip breaker 3 is also processed on the surface of the cutter head 2 by laser engraving.

[0024] Such as Figure 4 As shown in the enlarged diagram of , the angle range of the chip breaker angle α formed between the cutting edge 4 and the chip breaker 3 is 15°-25°.

[0025] The blade of the present invention can be any model in the ISO standard, and can also be a special model of a customized special shape.

[0026] The head material of the superhard blade can be PCD and PCBN. PCD is mainly used for processing non-ferrous metal materials such as aluminum alloy, and PCBN is mainly used for processing materials such as hardened st...

Abstract

The invention relates to a superhard blade with a chip groove. A tool bit is welded on a base, and the chip groove lower than a surface cutting edge is arranged on the tool bit. The blade can be of any type in the ISO (International Standardization Organization) standards, and can be of customized special shape and special type, the blade is designed with a single tool bit or multiple tool bits, the chip breaking groove can be processed on the surface of each tool bit, and different angles and shapes of the chip breaking groove can be designed according to the blade of different types to meet requirements on use and processing in actual working conditions. By the superhard blade with the chip breaking groove, the problem that workpieces are scratched or a tool is wound caused by continuous cutting during production is effectively solved, probability of abnormal damages caused by abrasion of the tool is lowered, and requirements on high-speed efficient cutting are met. The superhard blade with the chip breaking groove is mainly used for processing of non-ferrous metal products and hardened steel products in industries like aerospace, automobiles, machinery manufacturing, ships and chemistry.

Description

technical field [0001] The invention relates to a superhard blade with a chip breaker, which belongs to the field of machinery and tools. Background technique [0002] The density of pure aluminum is small (ρ=2.7g / cm3), about 1 / 3 of that of iron, and its melting point is low (660°C), so it is not suitable for structural materials, but it can be made into various aluminum alloys, such as duralumin, superhard Aluminum, anti-rust aluminum, cast aluminum, etc. The aluminum alloy formed by adding certain elements can also have high strength while maintaining the advantages of pure aluminum such as light weight, and the σb value can reach 24-60kgf / mm2 respectively. This makes its "specific strength" (the ratio of strength to specific gravity σb / ρ) better than many alloy steels, becoming an ideal structural material and the most widely used non-ferrous metal structural material in industry. It has been widely used in machinery manufacturing, shipbuilding, and chemical industry. ...
