Abstract
The invention discloses a kind of indexable tapering drilling tool, comprising: cutter hub, it includes knife bar, described knife bar front end are provided with two tapers and rotating part side by side；Blade, it includes two the first blades for boring, and multiple the second blade for reaming；Wherein, said two the first blade lays respectively at the top of two rotating parts, and the plurality of second blade is divided into two groups and is staggered on the lateral margin of two rotating parts.The indexable tapering drilling tool collection that the present invention provides is holed and countersinks all over the body, and working (machining) efficiency is high, and the hole wall surface quality formed after processing is good.
Description
Technical field
The present invention relates to a kind of machinery cutter, a kind of indexable tapering drilling tool, mainly
Need counterbore and require that pore area is bored on the large-scale workpieces such as steam turbine cylinder, railway track, large-scale steel mill
The hole of degree, heavy castings, the sampling etc. of forging.
Background technology
At present, heavy castings, forging plane on cannot realize with directly disposable one cutter
The processing of tapered hole.Processing tapered hole mainly uses and first uses drill bit counterbore in the plane, then from the teeth outwards
Again with the processing mode of taper hole at cornish bit expansion, this method more bothers, and working (machining) efficiency is low, causes
Production efficiency is low, may also connect tool marks, also is difficult in appearance be met；Also having is exactly with one one-tenth
Type cutter, realizes the processing of tapered hole, but the processing cost of this processing mode is high, if operation is not
Careful, it is possible to cause scrapping and the damage of cutter itself of workpiece, although this kind is easy to operate, but
The cost of charp tool is high and waste product is the most relatively high, and working (machining) efficiency is the highest, is difficult to meet the processing request of present situation.
Summary of the invention
The present invention has designed and developed a kind of novel indexable tapering drilling tool, the boring of this cutter collection and expansion
, working (machining) efficiency is high in hole, and the hole wall surface quality formed after processing is good.
The technical scheme that the present invention provides is:
A kind of indexable tapering drilling tool, comprising:
Cutter hub, it includes knife bar, described knife bar front end are provided with two tapers and rotating part side by side；
Blade, it includes two the first blades for boring, and multiple the second blade for reaming；
Wherein, said two the first blade lays respectively at the top of two rotating parts, the plurality of second cutter
Sheet is divided into two groups and is staggered on the lateral margin of two rotating parts.
Preferably, described cutter hub uses alloy steel material to make, and described blade uses Hardmetal materials
Make.
Preferably, said two the first blade on the top of described rotating part respectively with near described rotation
The axle center in portion and the edge of described rotating part are arranged.
Preferably, described cutter hub is provided with apopore in the position of described second blade.
Preferably, described cutter hub offers Cooling Holes bottom it.
Preferably, the lateral margin of said two rotating part offers the multiple recessed of each the second blade of receiving
Groove, the plurality of groove forms multiple step on side.
Preferably, said two rotating part forms helical form in solid.
The indexable tapering drilling tool that the present invention provides achieves the disposable processing of different tapered hole, solves
Prior art of having determined cannot disposably complete the defect offered of bellmouth, solve heavy castings, forging
Piece bores is deep and the difficult point of the big processing of tapering, instead of original elder generation's counterbore on taper hole, then enters with cornish bit
Row reaming, and it is also performed to the mode of tapering aperture processing, improve the working (machining) efficiency of back taper on counterbore,
Solve large-scale heavy-duty machine factory, steam turbine plant, electrical machinery plant, the technical barrier of shipyard, be the hole of a kind of advanced person
Process tool.The indexable use of its blade designed above, has saved processing cost simultaneously；Further
, cutter hub has Cooling Holes, the service life of blade and cutter hub can be increased.
Accompanying drawing explanation
Fig. 1 is the structural representation of indexable tapering drilling tool of the present invention.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art's reference
Description word can be implemented according to this.
As it is shown in figure 1, the present invention provides a kind of indexable tapering drilling tool, comprising:
Cutter hub 1, it includes that knife bar, described knife bar front end are provided with the rotating part 101 side by side of two tapers；
Blade, it includes two the first blades 201 and 202 for boring, and multiple for reaming
The second blade 203；Wherein, said two the first blade lays respectively at the top of two rotating parts, institute
State multiple second blade to be divided into two groups and be staggered on the lateral margin of two rotating parts 101.Can from Fig. 1
To see, multiple second blades divide into two groups, lays respectively on the lateral margin of one of them rotating part 101,
Form a gradient.These blades are fixed by screws on described cutter hub.
Further, described cutter hub uses alloy steel material to make, and described blade uses Hardmetal materials system
Become.According to the difference of rapidoprint, the Hardmetal materials of the optional different trades mark.
Further, said two the first blade on the top of described rotating part respectively with through described rotation
The axle center 201 in portion and the edge 202 of close described rotating part are arranged.They enter primarily as this cutter
Row is boring, can be described as again drill plate.
Further, the lateral margin of said two rotating part offers the multiple recessed of each the second blade of receiving
Groove, the plurality of groove forms multiple step 3 on side.The second blade on two rotating parts is to hand over
Staggered arrangement row, i.e. it is placed exactly in described second group of second blade when first group of second blade revolves turnback
Between interstitial site, this ensures that there on taper rotating part, two group of second blade defines one group
Complete cutting chain, it is ensured that remove all material on tapering.
Preferably, described cutter hub is provided with apopore 4 in the position of described second blade, opens bottom it
It is provided with Cooling Holes 5.The purpose of do so is to reduce the temperature that processing produces, and increases the use of blade
Life-span and the service life of cutter hub, also improve the stock-removing efficiency of cutter and the fineness of surface of the work simultaneously.
Moreover, said two rotating part forms helical form in solid.
The indexable tapering drilling tool that the present invention provides achieves the disposable processing of different tapered hole, solves
Prior art of having determined cannot disposably complete the defect offered of bellmouth, solve heavy castings, forging
Piece bores is deep and the difficult point of the big processing of tapering, instead of original elder generation's counterbore on taper hole, then enters with cornish bit
Row reaming, and it is also performed to the mode of tapering aperture processing, improve the working (machining) efficiency of back taper on counterbore,
Solve large-scale heavy-duty machine factory, steam turbine plant, electrical machinery plant, the technical barrier of shipyard, be the hole of a kind of advanced person
Process tool.The indexable use of its blade designed above, has saved processing cost simultaneously；Further
, cutter hub has Cooling Holes, the service life of blade and cutter hub can be increased.
Although embodiment of the present invention are disclosed as above, but it is not restricted to description and embodiment party
Listed utilization in formula, it can be applied to various applicable the field of the invention completely, for being familiar with ability
For the personnel in territory, be easily achieved other amendment, therefore without departing substantially from claim and etc. homotype
Enclosing under limited general concept, the present invention is not limited to specific details and shown here as the figure with description
Example.
