Description
Technical field
The present invention relates to cutting tool technical field, refer to a kind of machine holding carbide alloy treapanning drill especially.
Background technology
This drill bit is the cutting tool often used in machining, machine holding carbide alloy treapanning drill can be called according to using function, also have according to shape and be called hollow boring bit and annular cutting tool, as the term suggests be exactly the drill bit not boring core, this drill bit can process through hole, blind hole and cannelure, can jacking during processing through hole.People use spiral bit to have the history of more than 100 year.Brill core segment due to spiral bit is negative cutting angle completely, and cutting resistance is very large, so the cutting force 50%-60% of spiral bit is because the brill core of drill bit causes.Add the factor of steel, so spiral bit can not do very large.The larger darker hole of processing just must expand length by length, until reaming size reaches requirement from brill aperture.
Common cutter also exists slow, the inefficient difficult problem of speed all the time at processing macropore deep hole, is mostly subdrilling aperture adding man-hour before, then expansion step by step.The cutting speed of high-speed steel drill is the highest can not more than 30 ms/min; More compared with the high-speed steel drill material defects of large gauge, not easily overcome; Compared with the high-speed steel drill of large gauge, sharpening is very inconvenient again after being worn out, and these factors just limit the process velocity of whole workpiece.The appearance of hollow boring bit expands the cutting scope of drill bit, use relatively little power just can process macropore deep hole, also can the size of hollow boring bit be done very large, only use good or best steel on the cutting edge, not only reduce processing cost, also originally thinking that impossible processing technology mode had become possibility.
Overlaying processing can leave material core, can save material, reduces the power consumption of lathe.When needs make service check from material center taking-up sample, treapanning drill is that other kind of cutter institute is irreplaceable.Treapanning drill is generally used for the hole processing diameter more than 60 millimeters, and the jacking degree of depth can reach tens meters.Treapanning drill has external chip discharging and interior chip removal two kinds.The major advantage of external chip discharging cylindrical drill is that the equipment of required cutting fluid system is simple, but drilling rod has the helical flute be processed into, and thus strength and stiffness are poor, are used for jobbing work; Interior chip removal cylindrical drill relies on the pressure of cutting fluid, chip is gone out from drilling rod, therefore need to be equipped with comparatively complicated liquid-supplying system and solve sealing problem, but productivity ratio is high, is applicable to produce by batch.
Summary of the invention
The present invention proposes a kind of machine holding carbide alloy treapanning drill, solves in prior art and processes macropore, slow, the inefficient problem of deep hole speed in mechanical processing industry.
Technical scheme of the present invention is achieved in that
Machine holding carbide alloy treapanning drill, comprise shank, described shank one end is connected with process equipment main shaft, the other end is connected with sleeve shaped cutter hub, described sleeve shaped cutter hub outer wall is provided with 4-6 bar helical flute, 1 insert groove is all established in the end of every bar helical flute, carbide cutting blade is provided with in described insert groove, described carbide cutting blade is by can the housing screw of self-locking be fixed in described insert groove, the periphery of described carbide cutting blade is provided with cutting edge, and described cutting edge forms by two kinds of carbide cutting blades are superimposed.
As the improvement to technique scheme, described carbide cutting blade is equilateral triangle blade, convex triangular blade, square blade or diamond shaped insert.
As the further improvement to technique scheme, described cutting edge is by diamond shaped insert and convex triangular blade is superimposed forms.
As the further improvement to technique scheme, described cutting edge is by diamond shaped insert and equilateral triangle blade is superimposed forms.
As the further improvement to technique scheme, described cutting edge is by square blade and convex triangular blade is superimposed forms.
As the further improvement to technique scheme, described cutting edge is by square blade and equilateral triangle blade is superimposed forms.
As the improvement to technique scheme, the width of rebate of described helical flute is 3-5 times of described cutting edge length, the degree of depth of described helical flute is 1/2-1/3 times of described cutting edge length, and the degree of depth of described helical flute is 1:6-15 with the ratio of the width of rebate of described helical flute.
As the further improvement to technique scheme, described shank is Morse taper shank, the taper shank of 7:24, be threaded in handle and cylindrical staight shank any one.
After have employed technique scheme, the invention has the beneficial effects as follows:
In the process in normal process hole, the steel inside hole are all processed into iron filings, a large amount of energy will be consumed like this.The low consumed energy-conservation annular cutting tool of the high efficiency that patent of the present invention provides can carry out annular processing, the material sleeve of centre out, both the energy is saved like this, turn improve efficiency, also save raw material, cover material out can carry out chemical examination and the tension test of material, has very large realistic meaning especially for valuable rare metal.
Patent of the present invention utilizes the method for screws clamp that the carbide cutting blade of standard is fixed on cutter (carrying) body to carry out annular cutting.Owing to employing the alloy blade of high-quality and annular cutter hub, the potential function that both can play lathe to greatest extent carries out high speed trepanning, saves energy and reduce the cost again, low-carbon environment-friendly; Standard insert has several cutting edges simultaneously, when one of them cutting edge wears up to can not used time again, only need to change cutting edge, when all cutting edges of whole blade all wear and tear, only need more allowing blade replacement, it is little that this structure can reach cost, and utilization rate is high, also can reach energy-saving and cost-reducing, the object that low-carbon (LC) cuts.
High efficiency of the present invention is just to employ indexable machine holding carbide alloy cutting tip, and its cutting speed can reach more than 100 ms/min, and the specification of blade is general international standard, after blade abrasion, unclamp screw, blade is turned an angle, tighten screw and just can continue to use.Because the precision of blade is higher, the insert groove precision of installing on the cutter hub of blade is higher, within the workpiece accuracy that blade clamps aft-loaded airfoil again remains on the tolerance of permission.
