It is applicable to the brill milling demand having relatively big orifice to bore bridging plug soon. The fast junk mill that bore bridging plug and drilling efficiency can be greatly improved.
The technical solution adopted in the utility model is:
A kind of latus rectum class bridging plug special efficient flat-bottom grind shoes, including body, six lobe milling italics, YG hard alloy blocks and the milling body that reversely leads, described body one end connects reversely guiding milling body, described reverse guiding milling body and six lobe milling italics and connects; Having 7 passages being available for liquid circulation bottom six lobe milling italics, equally distributed six passages of annular are milling hydrophthalmia, and 1 passage at middle part is for rinsing hydrophthalmia; Six lobe milling italics and reversely uniform spreading weldering multilamellar YG hard alloy blocks between guiding milling body.
Eccentric flushing hydrophthalmia it is provided with bottom six lobe milling italics.
Described YG hard alloy blocks cross section becomes equilateral many rhombuses.
Six lobe milling italics and reversely uniform spreading weldering 4-6 layer YG hard alloy blocks between guiding milling body.
YG hard alloy blocks hardness is HRA91.
Described six lobe milling italic upper ends are the lotus shape of six lobes, and lower end is the cylinder of inclined bottom surface; Described reverse guiding milling body is the stage body coordinated with six inclined-planes, lobe milling italic lower end.
The beneficial effects of the utility model are:
This utility model is to provide a kind of special efficient junk mill boring bridging plug for latus rectum class soon. It is applicable to, to the fast brill milling demand boring bridging plug with relatively big orifice, the fast junk mill that bore bridging plug and drilling efficiency to be greatly improved.
Flat-bottom grind shoes uniform spreading weldering multilamellar (4-6 layer) is adopted to have many rhombuses hard alloy stereo block of multidirectional acute angle, by cutting, grinding, the comprehensive function such as tear and improve milling effect, the high-velocity fluid rinsing hydrophthalmia outflow from junk mill bias directly rinses chip and deposit bottom bridging plug by bridging plug central passage, eliminate the basic sediment impact on boring mill, simultaneously, because of its eccentric design, it is possible to realize all standing to milling face. This junk mill can realize the quick drill milling requirement to parts such as bridging plug caulking gum, aluminium alloy and nonmetallic composites, is maintained with bottom bridging plug and cleans, improves the drilling efficiency between two bridging plugs.

Detailed description of the invention
Embodiment 1:
Existing boring mill and drilling efficiency is relatively low, problem that bridging plug bottom chip and deposit cannot be cleaned in time to overcome, this utility model provides a kind of latus rectum class bridging plug special efficient junk mill as shown in Figure 1, Figure 2, Figure 3, Figure 4. It is applicable to the brill milling demand having relatively big orifice to bore bridging plug soon. The fast junk mill that bore bridging plug and drilling efficiency can be greatly improved.
A kind of latus rectum class bridging plug special efficient flat-bottom grind shoes, including body 1, six lobe milling italic 2, YG hard alloy blocks 5 and the milling body 6 that reversely leads, described body 1 one end connects reversely guiding milling body 6, and described reverse guiding milling body 6 is connected with six lobe milling italics 2; Having 7 passages being available for liquid circulation bottom six lobe milling italics 2, equally distributed six passages of annular are milling hydrophthalmia 3, and 1 passage at middle part is for rinsing hydrophthalmia 4; Six lobe milling italics 2 and reversely uniform spreading weldering multilamellar YG hard alloy blocks 5 between guiding milling body 6.
Flat-bottom grind shoes uniform spreading weldering multilamellar is adopted to have many rhombuses hard alloy stereo block and the YG hard alloy blocks 5 of multidirectional acute angle, by cutting, grinding, the comprehensive function such as tear and improve milling effect, the high-velocity fluid rinsing hydrophthalmia outflow from junk mill bias directly rinses chip and deposit bottom bridging plug by bridging plug central passage, eliminate the basic sediment impact on boring mill, simultaneously, because of its eccentric design, it is possible to realize all standing to milling face.
