The utility model discloses collection drilling cutter sword, shaping sword, to mill the sword as an organic whole, once accomplishes A number of processes, has reduced the work load of processing work piece, has improved machining efficiency, adopts the multistage design through the correction anterior angle at the shaping sword simultaneously, has improved the stock -removing efficiency of cutter, has prolonged the life of cutter.
Description
Technical field
This utility model relates to five metals machining tool, specifically, is a kind of process the interior cold step drill in hole in common rail rail body.
Background technology
nullDevelopment along with machinery industry，User's crudy to product、Process reliability、It is proposed higher requirement the date of delivery of cutter etc.，Using cutter when workpiece is processed，Generally all can by separately performed for different operations，First have to workpiece is holed，Then again the aperture molding 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，The correction angle design form of the molding blade of traditional step drill is single，It is all adopt first stage building mostly，When processing work molding，Cutter needs the dynamics used bigger，Therefore workpiece stock-removing efficiency is not high，The demand of efficiently and accurately to work pieces process cannot be met in modern production，And after using for a long time，Serious wear to cutter，Shorten cutting-tool's used life，It is unfavorable for saving production cost.
Utility model content
Utility model purpose: the purpose of this utility model is in that to provide for weak point of the prior art a kind of and processes in common rail rail body cold step drill in hole, and the multistage design of molding blade contributes to substantially increasing stock-removing efficiency and the service life of cutter.
Technical scheme: for reaching above-mentioned purpose, described in the utility model a kind of process the interior cold step drill in hole in common rail rail body, including shank and blade, described shank runs through and sets into aquaporin, and described blade sets gradually boring blade, molding blade, milling cutter, chip area vertically from blade head to blade afterbody.
Preferably, described boring blade, molding blade, milling cutter are one-body molded.
Preferably, described shank and blade are one-body molded.
Preferably, the back of described interior cold step drill is provided with and enters the osculum that aquaporin communicates,
Described osculum is towards the direction of chip area.
Preferably, described shank end is provided with and enters the inlet opening that aquaporin communicates.
Preferably, described molding blade is provided with correction anterior angle, and described correction anterior angle is divided into three to revise section, first paragraph and central shaft angle are 22 °, second segment and central shaft angle are 30, and the 3rd section is 90 ° with central shaft angle, and described second segment and the 3rd section of junction are arc.
Compared with prior art, the beneficial effects of the utility model are:
(1) described in the utility model a kind of the interior cold step drill in hole in common rail rail body is processed, the multistage design of the correction anterior angle of described molding blade, be conducive to improve the stock-removing efficiency of cutter, extend cutting-tool's used life.
(2) this utility model integrates boring blade, molding blade, milling cutter, is once completed by multiple working procedure, decreases the workload of processing work, improves working (machining) efficiency, reduces production cost.
(3) this utility model is by arranging discharge outlet at the back of interior cold step drill, it is prevented that the chip of cutting blocks into aquaporin, it is ensured that the blade cooling effect when processing work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of molding blade of the present utility model.
In figure: 1 shank, 2 blades, 11 water inlets, 12 enter aquaporin, 21 boring blades, 22 molding blades, 23 milling cutters, 24 osculums, 25 chip areas, 221 revise anterior angle, 221a first paragraph, 221b second segment, 221c the 3rd section.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, it is further elucidated with this utility model.
As shown in Figure 1-2 a kind of processes the interior cold step drill in hole in common rail rail body, including shank 1 and blade 2, described shank 1 runs through and sets into aquaporin 3, and described blade 2 sets gradually boring blade 21, molding blade 22, milling cutter 23, chip area 25 vertically from blade 2 head to blade 2 afterbody.
