Abstract
The invention provides a machine clamp hard alloy jacking drill bit which comprises a shank, relates to the technical field of cutting tools, and solves the problem that large and deep hole machine in machining industries are slow and inefficient in the prior art. One end of the shank is connected with the spindle of a machining device, and the other end thereof is connected with a sleeve-shaped cutter body. 4-6 spiral chip grooves are formed in the outer wall of the sleeve-shaped cutter body. The end of each spiral chip groove is provided with a blade groove. A hard alloy cutting blade is disposed in each blade groove. Each hard alloy cutting blade is fixed in the corresponding blade groove through a self-locking compressing screw. A cutting edge which is stacked by two kinds of hard alloy blades is formed on the periphery of each hard alloy cutting blade.
Description
Technical field
The present invention relates to cutting tool technical field, refer to especially a kind of machine holding carbide alloy treapanning drill.
Background technology
This drill bit is the cutting tool often using in machining, according to using function can be called machine holding carbide alloy treapanning drill, according to shape, also there are the hollow boring bit of being called and annular cutting tool, as the term suggests be exactly the drill bit that does not bore core, this drill bit can be processed 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.Because the brill core segment of spiral bit is negative cutting angle completely, cutting resistance is very large, so the cutting force 50%-60% of spiral bit is brill core due to drill bit, causes.Add the factor of steel, so spiral bit can not be done very greatly.The larger darker hole of processing just must start to expand length by length from boring aperture, until reaming size reaches requirement.
Common cutter 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 be over 30 ms/min; The high-speed steel drill material defects of larger specification is more, is difficult for overcoming; Sharpening is very inconvenient again after being worn out for the high-speed steel drill of larger specification, and these factors have just limited the process velocity of whole workpiece.The appearance of hollow boring bit has expanded 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 greatly, only on cutting edge, use good or best steel, not only reduced processing cost, also originally thinking that impossible processing technology mode may become.
Overlaying processing can leave material core, can save material, reduces the power consumption of lathe.When needs take out sample and make service check from material center, treapanning drill is that other kind of cutter institute is irreplaceable.Treapanning drill is generally used for processing 60 millimeters of above holes of diameter, and the jacking degree of depth can reach tens meters.Treapanning drill has two kinds of external chip discharging and interior chip removals.The major advantage of external chip discharging cylindrical drill is that the equipment of required cutting fluid system is simple, but on drilling rod, has the helical flute being processed into, thereby strength and stiffness are poor, are used for jobbing work; Interior chip removal cylindrical drill relies on the pressure of cutting fluid, and smear metal 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, has solved the interior processing of mechanical processing industry macropore, slow, the inefficient problem of deep hole speed in prior art.
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 helical flute, in described insert groove, be provided with carbide cutting blade, described carbide cutting blade is fixed in described insert groove by housing screw that can self-locking, the periphery of described carbide cutting blade is provided with cutting edge, and described cutting edge is by two kinds of carbide chip superimposed compositions.
As the improvement to technique scheme, described carbide chip is equilateral triangle blade, protruding triangular blade, square blade or diamond shaped insert.
As the further improvement to technique scheme, described cutting edge is by diamond shaped insert and protruding 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 protruding 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 1:3-5 with the ratio of the width of rebate of described helical flute.
As the further improvement to technique scheme, described shank be Morse taper shank, 7:24 taper shank, any in handle and cylindrical staight shank is threaded.
Adopted after technique scheme, the invention has the beneficial effects as follows:
In the process in normal process hole, the steel of the inside, hole are all processed into iron filings, to consume a large amount of energy like this.The low consumed energy-conservation annular cutting tool of high efficiency that patent of the present invention provides can carry out annular processing, middle material sleeve out, so both saved the energy, improved again efficiency, raw material have also been saved, cover material out can carry out chemical examination and the tension test of material, has very large realistic meaning especially for valuable rare metal.
To be the method for utilizing screws clamp be fixed on the carbide chip of standard on cutter (carrying) body, to carry out annular cutting patent of the present invention.Owing to having used alloy blade and the annular cutter hub of high-quality, both can bring into play to greatest extent the potential function of lathe and carry out high speed trepanning, energy-saving and cost-reducing again, low-carbon environment-friendly; Standard insert has several cutting edges simultaneously, when one of them cutting edge wears up to the 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 of low-carbon (LC) cutting.
High efficiency of the present invention is just to have used indexable machine holding carbide alloy blade, 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 to an angle, tighten screw and just can continue to use.Because the precision of blade is higher, the insert groove precision on the cutter hub of installation blade is higher, and the workpiece accuracy that blade clamps rear processing again remains in the tolerance of permission.
