Abstract
The utility model relates to a converter tapping hole drill, in particular to a water/wind-cooled converter tapping hole drill, which mainly solves the technical problem that the water-cooling passage of the conventional drill can be easily blocked. The technical scheme of the utility model is that: the drill comprises a drill stem and a spiral connecting rod, the drill stem is provided with an internal-threaded connector, and is a hollow body, one end of which is provided with a bit, the spiral connecting rod is screwed into the drill stem, and is a hollow body as well, and the internal thread of the connector of the drill stem is provided with a water outlet groove which is perpendicular to the thread direction. In terms of water cooling, the spiral line of the spiral connecting rod is provided with a spiral sealing groove and sealed by a sealing strip. The utility model is applicable to drills for caterpillar engineering machines (also called furnace-dismantling machines), such as the replacement of converter tapping holes by furnace-dismantling and ladle-dismantling machines in steel works.
Description
Technical field
The utility model relates to a kind of converter taphole drilling tool, and particularly a kind of water/air-cooled converter taphole drilling tool is applicable to that tracked construction equipment (claiming disassembling furnace machine again) uses drilling tool, as: steelworks is torn stove open, the bale opener converter taphole is changed.
Background technology
At present, drilling tool of using of each tradition of domestic metallurgy industry because: the Drill Steel body produces the alloy cutter head heat damage that high heat causes the Drill Steel body to be subjected to thermal wear or inlays after meeting cold steel on frame of the bit.Cause that spare parts consumption is big, overhaul efficiency is low and problem such as tapping time lengthening.
Existing patent CN2915873Y brings out water to reach cooling purpose from the water inlet of Drill Steel body end from drill bit at the middle cold through hole of fetching water of Drill Steel body, water coolant.Drill bit cooling hole Chang Yingang slag stops up and causes cooling to interrupt during actual job, easily causes security incident because of water coolant contacts with molten iron simultaneously.
The utility model content
The purpose of this utility model provides a kind of water/air-cooled converter taphole drilling tool that in use can cool off drilling tool, mainly solves the technical problem that existing drilling tool water-cooling channel stops up easily.
The technical solution of the utility model is: a kind of water/air-cooled converter taphole drilling tool, form by drilling rod that has female screw connection and stirrup, drilling rod is the hollow body that an end has drill bit, stirrup screws in drilling rod, stirrup also is a hollow body, has effluent trough at the connecting joint internal thread of drilling rod one perpendicular to hand of spiral.
During water-cooled, the spiral-line of stirrup has the helixseal groove and adopts the sealed strip sealing.Water coolant is intake to the drill bit top and the sealed cistern that revolves by stirrup returns the water outlet of connecting joint effluent trough to reach the circulation cooling performance from the stirrup end.
The beneficial effects of the utility model: the utility model drilling tool guarantees because of good cooling is arranged in work, can guarantee under the hot operation condition, to cut indeformable, as to have improved drilling tool work-ing life, reduce spare parts consumption, improve the operation overhaul efficiency, have remarkable economic efficiency.
Description of drawings
Fig. 1 is the utility model assembly structure synoptic diagram
Among the figure: 1-stirrup, 2-drilling rod, 3-connecting joint, 4-rotary seal groove, 5-prosopyle, 6-effluent trough.
Embodiment:
With reference to Fig. 1, a kind of water/air-cooled converter taphole drilling tool, form by drilling rod 2 that has female screw connection 3 and stirrup 1, drilling rod 2 is the hollow body that an end has drill bit, stirrup 1 screws in drilling rod 2, stirrup 1 also is a hollow body, has effluent trough 6 at the connecting joint internal thread of drilling rod one perpendicular to hand of spiral.
During water-cooled, the spiral-line of stirrup 1 has helixseal groove 4 and adopts the sealed strip sealing.Water coolant is intake from stirrup end prosopyle 5 to the drill bit top and the spiral-line by stirrup 1 returns 6 water outlets of connecting joint effluent trough to reach the circulation cooling performance.
When adopting pressurized air cold, the spiral-line of stirrup 1 need not to offer the helixseal groove.
Claims (2)
1. water/air-cooled converter taphole drilling tool, it is characterized in that, form by drilling rod that has female screw connection and stirrup, drilling rod is the hollow body that an end has drill bit, stirrup screws in drilling rod, stirrup also is a hollow body, has effluent trough at the connecting joint internal thread of drilling rod one perpendicular to hand of spiral.
