Abstract
The utility model discloses an interior cold ladder straight -flute drill in nonrust steel valve seat hole of processing martensite, including stalk portion and cutting part, the stalk portion is equipped with the passageway that entries, the cutting part sets gradually first drilling, chamfer sword, second drilling and drill way shaping sword along the axial from the cutting part head to the cutting part afterbody. An interior cold ladder straight -flute drill in nonrust steel valve seat hole of processing martensite, collection drilling, chamfer sword and drill way shaping sword are as an organic whole, are the cutters of a multi -functional complex, once accomplish the A number of processes of product processing, have alleviateed the work load of processing work piece, have practiced thrift manufacturing cost.
Description
Technical field
This utility model relates to five metals machining tool, specifically, is a kind of interior cold ladder straight-flute drill processing martensitic stain less steel valve seat orifice.
Background technology
Development along with machinery industry, user's crudy to product, process reliability, it is proposed higher requirement the date of delivery of cutter etc., but use cutter in the process of converted products, the phenomenon of cutter interference easily occurs, CNC Machining Tool interference refers in the course of processing, the non-processing object of Tool in Cutting, or Tool in Cutting is beyond intended scope, be also called cutter cross cut patch and collision phenomenon, or Tool in Cutting is beyond intended scope, cross also referred to as cutter and cut and collision phenomenon, wherein cutter and lathe, interference between fixture is referred to as to do something in disregard of obstacles and relates to, once produce this interference, cutter will be produced, the hard loss of lathe or fixture, the especially easy generation of this phenomenon is in Surface NC Machining, thus how to resolve cutter cutter interference problem in the course of processing in digital control processing field, play vital effect, in addition, using cutter when workpiece is processed at present, generally all can by separately performed for different operations, first have to workpiece is holed, then again the aperture forming cutter in hole is carried out chamfer machining, workpiece operation break-down is processed, not only the speed of processing work is slow, also adds additional the workload of workman, can not meet in modern production the demand of efficiently and accurately to work pieces process.
Utility model content
Utility model purpose: the purpose of this utility model is in that to provide a kind of cold ladder straight-flute drill in martensitic stain less steel valve seat orifice of processing for weak point of the prior art, integrate boring, chamfering blades and aperture forming cutter, be the cutter of a kind of multi-functional compound.
Technical scheme: for reaching above-mentioned purpose, a kind of interior cold ladder straight-flute drill processing martensitic stain less steel valve seat orifice described in the utility model, including shank and blade, described shank is provided with two-way and enters aquaporin, and described blade sets gradually the first boring, chamfering blades, the second boring and aperture forming cutter vertically from blade head to blade afterbody.
Further, described first boring, chamfering blades, the second boring, the stepped blade that is distributed in of aperture forming cutter, and the length of the first boring is more than the length of the second boring.
Further, described blade is additionally provided with the chip area of indent.
Further, described blade arranges and enters the discharge outlet that aquaporin communicates, and described discharge outlet is towards chip area direction.
Further, the head angle of described first boring is 120 ��.
Further, described chamfering blades and shank central shaft angle are 59 ��.
Further, described aperture forming cutter and shank central shaft angle are 52 ��.
Compared with prior art, the beneficial effects of the utility model are:
(1) a kind of interior cold ladder straight-flute drill processing martensitic stain less steel valve seat orifice described in the utility model, integrate boring, chamfering blades and aperture forming cutter, it it is the cutter of a kind of multi-functional compound, the multiple working procedure of Product processing is once completed, alleviate the workload of processing work, save production cost.
(2) interior cold ladder straight-flute drill described in the utility model, the first boring on blade, chamfering blades, the second boring, the stepped distribution of aperture forming cutter, can effectively prevent cutter from the phenomenon of cutter interference occurring when processing work, it is simple to Tool in Cutting instrument.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of blade of the present utility model.
In figure: 1 shank, 2 blades, 3 enter aquaporin, 4 first borings, 5 chamfering blades, 6 second borings, 7 aperture forming cutters, 8 chip areas, 9 discharge outlet.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, it is further elucidated with this utility model.
A kind of interior cold ladder straight-flute drill processing martensitic stain less steel valve seat orifice as shown in Figure 1, including shank 1 and blade 2, described shank 1 is provided with two-way and enters aquaporin 3, and described blade 2 sets gradually the first boring 4 vertically from blade 2 head to blade 2 afterbody, chamfering blades 5, second holes 6 and aperture forming cutter 7.
Specifically, described first boring 4, chamfering blades the 5, second boring 6, the stepped blade 2 that is distributed in of aperture forming cutter 7, and the length of the first boring 4 is more than the length of the second boring 6.
Specifically, described blade 2 is additionally provided with the chip area 8 of indent.
Specifically, described blade 2 arranges and enters the discharge outlet 9 that aquaporin 3 communicates, and described discharge outlet 9 is towards chip area 8 direction.
Specifically, the head angle of described first boring 4 is 120 ��.
Specifically, described chamfering blades 5 is 59 �� with shank 1 central shaft angle.
Specifically, described aperture forming cutter 7 and shank 1 central shaft angle are 52 ��.
Forming cutter each several part described in the utility model carrys out control accuracy by strict processing technique, and the total length of forming cutter is 50.8mm, and shank 1 diameter is 6mm, and its margin of tolerance is-0.008mm-0, and the length of blade 2 is 13mm.
Embodiment is merely to illustrate this utility model rather than limits scope of the present utility model, after having read this utility model, the amendment of the various equivalent form of values of the present utility model is all fallen within the application claims limited range by those skilled in the art.
