Embodiment 1

[0031] This embodiment discloses an internally cooled forming turning tool suitable for low-temperature minimal-quantity lubrication. The internally-cooled forming turning tool suitable for low-temperature minimal-quantity lubrication includes: a tool body 4, a main cold air channel 9, a main nozzle 1 and multiple A side nozzle 2, the side of the cutter body 4 is connected with a three-way joint 3, the main cold air channel 9 is arranged in the cutter body 4 and connected with the three-way joint 3, through the three-way joint 3 into the lubricating head and compression cooling For gas, the main spray head 1 and the plurality of side spray heads 2 are connected to the main cold air passage 9 through the secondary cold air passage 8, and the cooling lubricating oil is sprayed outward through the main spray head 1 and the side spray heads 2.

[0032] The bottom of the cutter body 4 is in the shape of a cuboid, the top of the cutter body 4 is processed with a dovetail tenon 10, th...

Embodiment 2

[0036] This embodiment discloses a method for preparing an internally cooled forming turning tool suitable for low-temperature minimal-quantity lubrication. The method is as follows:

[0037] Regrind the four sides of the blank on the surface grinder to improve the precision of subsequent processing. The blank of the tool is a purchased high-speed steel bar;

[0038] Use slow wire cutting to process the rake angle, blade-shaped part and dovetail tenon of the turning tool 10;

[0039] Install the tool on the pads with angles of 22° and 12° successively, and the pads are installed on the clamping seat of the machine tool, and the electrode wire moves according to the preset program to cut out the rake angle and 5 parts of the elliptical blade shape;

[0040] Install the tool vertically on the clamping seat, and the electrode wire moves according to the preset program to cut out 10 parts of the dovetail;

[0041] After the cutting is completed, the dimensional accuracy of the bl...

Abstract

The invention discloses an inner-cooling type forming turning tool suitable for low-temperature minimal quantity lubrication and a preparation method of the inner-cooling type forming turning tool. The inner-cooling type forming turning tool suitable for low-temperature minimal quantity lubrication comprises a tool body, a main cold air channel, a main spray head and a plurality of lateral spray heads. The side face of the tool body is connected with a three-way joint. The main cold air channel is arranged in the tool body and connected with the three-way joint. Lubricating oil and compressedcooling air are injected through the three-way joint. The main spray head and the lateral spray heads are connected with the main cold air channel through secondary cold air channels. Cooled lubricating oil is sprayed outwards through the main spray head and the lateral spray heads. The problem that an existing turning tool is difficult to cool rapidly and short in service life is solved.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to an internal cooling forming turning tool suitable for low-temperature micro-quantity lubrication and a preparation method thereof. Background technique [0002] Superalloys are multi-component complex alloys with good thermal strength, thermal stability and thermal fatigue properties. They can work in high temperature oxidation atmospheres and corrosive conditions of 600-1000 degrees. They are strengthened by solid solution and aging methods. Better strength and creep resistance can be obtained. Therefore, it is an important structural material in the aerospace industry, and is often used in the manufacture of turbine blades, turbine disks, combustion chambers, turbine drive shafts, and steam turbine rotors in aeroengines. Superalloys have many advantages, but they also make their machining more difficult than other materials. In the cutting process of superalloys...
