Abstract

The utility model provides a deep hole trepanning tool. The deep hole trepanning tool comprises hard alloy tool blocks, a tool body and a Morse taper shank, wherein the tool body is fixedly connected with the Morse taper shank; the outer edge of the tool body is uniformly provided with four U-shaped tool slots; after the hard alloy tool blocks are closely attached to wedge blocks, the hard alloy tool blocks and the wedge blocks are arranged in the U-shaped tool slots. Each hard alloy tool block comprises a hard alloy blade and a tool block, the hard alloy blade is welded to the tool block and is flush with the end face of the tool block; the hard alloy blade is made of a hard alloy YG8 material. One end face of each U-shaped tool slot is provided with a tooth grain structure, and the other end face corresponding to the end face is provided with a slope; one end face of each tool block is provided with a tooth grain structure and the other end face, corresponding to the corresponding wedge block, of the tool block is provided with a slope; the tool blocks and the U-shaped tool slots are matched through the tooth grain structures, and the wedge blocks are matched with the U-shaped tool slots through the slopes. The deep hole trepanning tool has the advantages of high durability, low cost, long service life and the like on the basis of the traditional advantages of the deep hole trepanning tool.

Description

Deep hole trepanning tool

Technical field

The utility model relates to a kind of deep hole trepanning tool, belongs to cutting-tool engineering field.

Background technology

The length that deep hole in mechanical processing technique typically refers to deep hole is greater than five times of above holes of diameter.Progress and industrial expansion along with technology, the application of Deep-Hole Drilling Technology is more and more extensive, nearly all manufacture department all can apply, as there is application in the manufacturing sectors such as Petro-Chemical Machinery, aircraft industry, shipbuilding, metallurgy, generating equipment, rubber manufacturing machinery, wood processing equipment.

Deep hole trepanning tool is cutter indispensable in Deep-Hole Drilling Technology, and it has the following advantages: under the condition of workpiece and cutter rotation, have higher metal excision speed; Expensive or will test when analyzing core at workpiece material, can retain complete material core material, reduce costs; During the larger hole of jacking diameter, make core separated with body, by this part from workpiece centre position whole taking-up, recycling, reduced waste.

Though the deep hole trepanning tool adopting has at present improved stock utilization to a great extent, reduced the waste of precious metal material, reduced labour intensity, improved production efficiency, in production practices, obtained extraordinary effect, but still there is defect and deficiency: because deep hole trepanning tool is to work under the mal-condition of high temperature, violent friction, so the poor durability of cutter, cutting rate is undesirable; Owing to adopting solid tool, after tool wear, cannot reprocess, will cause whole cutter to be scrapped, so the service life of cutter is short, strengthened the use cost of cutter.

Utility model content

For above deficiency, the purpose of this utility model is to provide the deep hole trepanning tool that a kind of use cost is low, cutter life is long.

The technical solution of the utility model: deep hole trepanning tool, comprise carbide tool-block, cutter hub and Morse taper shank three parts, wherein cutter hub is fixedly connected with Morse taper shank, in the outer rim of cutter hub, be evenly provided with four U-shaped cutter grooves, after carbide tool-block fits tightly with voussoir, will be encased in U-shaped cutter groove together with it.

Described carbide tool-block comprises carbide chip and cutter piece two parts, carbide chip be welded on cutter piece and with the end face of cutter piece, carbide chip adopts carbide alloy YG 8 material.

One end face of described U-shaped cutter groove is made groove structure, corresponding other end bevel; One end face of described cutter piece is made groove structure, the other end bevel of corresponding voussoir; Cutter piece matches by groove structure with U-shaped cutter groove, and voussoir matches by inclined-plane with U-shaped cutter groove.

Inclined-plane on described U-shaped cutter groove and the inclined-plane on voussoir be 5 ° ± 5 '.

The beneficial effects of the utility model: the utility model has on the basis of deep hole trepanning tool traditional advantages, have more the advantages such as durability is good, cost is low, long service life; Carbide chip on carbide tool-block is damaged, this cutter piece can be cleaned with a pointed instrument from cutter hub, change new cutter piece, so just effectively extended the service life of cutter, avoided cutter in the past to scrap the higher problem of use cost of bringing because of cutter simultaneously; Because carbide chip is selected carbide alloy YG 8 material, therefore there is good normal temperature and high temperature hardness, be suitable for the difficult-to-machine materials such as high-strength heat-resistance steel, high temperature alloy, titanium alloy; Due between cutter piece and U-shaped cutter groove, adopt groove structure to match, between voussoir and U-shaped cutter groove, adopt inclined-plane to match, removing and installing of cutter piece and U-shaped cutter groove is convenient in the effective like this location between cutter piece and U-shaped cutter groove, fixing of having realized simultaneously.
