Embodiment 1

[0035] Such as Figure 6-1 As shown, the ant's mandibles can lift objects several times heavier than the body, and have good drag reduction, lubrication and anti-adhesion properties, and the pits and hairs on the surface play a certain role. A schematic diagram of the two mandibles of an ant and the pits and hairs on the mandibles is shown in Figure 6-2 , Figure 6-3 for Figure 6-2 Enlarged view of part A. The present invention is a high-hardness surface microstructure implanted with carbon fiber, which is a high-hardness surface microstructure imitating the surface of the ant's mouthparts (high-hardness mandible surface + bristles), and a bionic microstructure is set on the high-hardness surface, and the high-hardness surface can be Be blade, titanium alloy surface, granite surface etc.; The high hardness surface of present embodiment is the rake face of turning tool, as figure 2 As shown, that is, this embodiment is the microstructure of the rake face of the turning t...

Embodiment 2

[0037] The rake face is provided with a turning tool with a microstructure implanted with carbon fibers. The rake face of the turning tool is provided with the microstructure implanted with carbon fibers in Example 1, and the material used is high-speed steel (W6Mo5Cr4V2).

Embodiment 3

[0039] In embodiment 2, the preparation method of the microstructure of the rake face of the turning tool implanted with carbon fibers is as follows:

[0040] Step 1. Use natural diamond to make a single-point diamond embossing knife for embossing the center rounding table pit, wherein the single-point diamond embossing knife is in the shape of a rounding table, and the busbar of the single-point diamond embossing knife and the clamp of the central axis Angle θ 2 = 45°, the minimum diameter d of a single-point diamond imprinting knife 2 =0.04mm; the total height h of the single-point diamond embossing knife 2 = 0.15 mm.

[0041] Step 2. First, fix the vibration exciter 1 with a frequency of 100 Hz and an amplitude of 0.1 mm on the Z-axis slider 12 of the single-point diamond three-dimensional drive mechanism of the vibrating single-point diamond imprinting instrument, and place the output rod of the vibration exciter 1 It is fixedly connected with the tool handle 2 inlaid w...

Abstract

The invention discloses a carbon fiber implanted high-hardness surface microstructure and a preparation method and device thereof. The service life of an existing high-hardness surface needs to be prolonged. According to the invention, a carbon fiber inverted cone is welded in a central inverted circular truncated cone pit of each bionic microstructure. The preparation method of the microstructurecomprises the following steps: imprinting a bionic microstructure group by using a single-point diamond imprinting knife, and then welding a carbon fiber inverted cone in each central inverted circular truncated cone pit of the bionic microstructure group. The microstructure preparation device comprises a vibration single-point diamond imprinting instrument, a single-point diamond imprinting cutter, a vibration single-point diamond welding instrument and a diamond welding cutter, the vibration single-point diamond imprinting instrument comprises a single-point diamond three-dimensional driving mechanism and a first vibration exciter. The vibration single-point diamond welding instrument comprises a single-point diamond three-dimensional driving mechanism and a second vibration exciter. The hardness, strength, wear resistance and precision of the high-hardness surface can be improved.

Description

technical field [0001] The invention relates to the field of design and preparation of high-hardness surface composite microstructures, in particular to a high-hardness surface microstructure implanted with carbon fibers and its preparation method and device. Background technique [0002] High-hardness surface microstructures are widely used in processing difficult-to-machine materials such as titanium alloys, ceramics, and high-temperature alloys, such as high-hardness surface tools such as turning tools and milling cutters, which have large cutting forces when processing difficult-to-machine materials in aerospace, marine and automotive fields. , serious tool wear and other issues, so how to improve the cutting performance of the tool and prolong the tool life has become a hot spot of technical research. [0003] At present, the research on carbon fiber on high-hardness surface is very limited. For example, the patent with publication number 108325803A discloses a method f...
