Abstract
The utility model relates to the field of pipeline mounting and pipeline maintaining, in particular to a steel and magnetic sleeve type drill bit. The steel and magnetic sleeve type drill bit comprises a cutter body, a cutter handle is arranged at one end of the cutter body, the cutter body is of a cylinder shape, a cylindrical cavity is arranged inside the cutter body, an iron sucking magnet is arranged on the cutter body, and a blade is arranged at the other end of the cutter body. An iron sucking magnet device is arranged inside the cylindrical cavity of the cutter body. One edge, close to the inner side of the cutter body, of the blade forms an included angle of 10 degrees with one edge, on the outer side of the cutter body, of the blade. After the steel and magnetic sleeve type drill bit is used for drilling a pipeline, the drill bit can drop from cake-shaped steel scraps and fall into the pipeline, the annular iron sucking magnet which can move up and down on the inner side of the cutter body is arranged on the inner side of the cutter body, after drilling is completed, the iron sucking magnet takes back and sucks the cake-shaped steel scraps, the scraps are prevented from falling into the pipeline, the iron sucking magnet attracts the scraps which are left by drilling, and the problem that a conveying pipeline is plugged caused by left scraps in drilling can be effectively solved.
Description
Technical field
The utility model relates to pipeline to be installed and the pipeline maintenance field, relates in particular to a kind of iron and steel and adds magnetosheath formula drill bit.
Background technology
The transport pipeline of water, oil and gas etc. is because damages such as burn into is run-down may appear in the cause of daily long use or burst accident, perhaps at transport pipeline arm etc. is installed, all need be got out the opening of certain diameter at original transport pipeline.At present, drill bit commonly used is generally common screw thread drill bit, this drill bit drill through pipeline the time be will will will drill through opening pull out of hole from its center, drill through the opening to necessary requirement then always, the pipeline trash that the whole opening that is drilled through in the process that drills through produces can directly enter transport pipeline, stops up or influences transport pipeline.
The utility model content
Technical problem to be solved in the utility model provides and a kind of iron and steel that produces the ferrous waste taking-up in the boring procedure can be added magnetosheath formula drill bit.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of iron and steel adds magnetosheath formula drill bit, comprise cutter hub, one end of described cutter hub is equipped with handle of a knife, described cutter hub is cylindrical cutter body, the inside of described cutter hub is cylindrical cavity, it is ferromagnetic that described cutter hub is provided with suction, and the other end of described cutter hub is blade.
The beneficial effects of the utility model are: the periphery that need not always get into the hole that will drill through from the center in the hole that will drill through, reduced labour intensity and to the loss of drill bit, arrange at described cutter hub and to inhale ferromagneticly, the waste material that boring is stayed holds and makes the transport pipeline of being holed can not stop up because of the waste material of leaving over.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, it is ferromagnetic to be provided with described suction in the cylindrical cavity of described cutter hub.
Adopt above-mentioned further beneficial effect to be, be arranged in the described cylindrical cavity described suction is ferromagnetic, the scrap metal that boring is produced directly is adsorbed in the described cylindrical cavity, be that cavity can be used as the place of collecting waste material, more effectively avoided the obstruction of transport pipeline, also made design of the present utility model more reasonable.
Further, described blade is serrated edge.
Further, described handle of a knife is the regular hexagon handle of a knife of hollow.
Further, the inner surface of described handle of a knife is provided with screw thread.
Further, one side described blade near one side of described cutter hub inboard with becomes ten to spend angles near the described cutter hub outside.
Adopt the beneficial effect of above-mentioned further scheme to be: one side with the be designed to ten degree angles of blade near one side with the close described cutter hub outside of described cutter hub inboard, make last what drill through, pipeline near the cutter hub inboard drills earlier, if do not have angle, be flat, can being difficult to last drilling at last of drilling through.
Description of drawings
Fig. 1 is right view of the present utility model;
Fig. 2 is that the utility model is along the schematic cross-section of A-A among Fig. 1;
Fig. 3 is the partial schematic diagram of the utility model blade.
In the accompanying drawing, the parts of each label representative are as follows:
1, handle of a knife, 2, cutter hub, 3, blade, 4, inhale ferromagnetic.
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not for limiting scope of the present utility model.
As shown in Figure 1, Fig. 1 comprises the right view of 4 serrated edge for the utility model.
Fig. 2 is that the utility model is along the schematic cross-section of A-A among Fig. 1, a kind of iron and steel adds magnetosheath formula drill bit, comprise cutter hub 2, one end of described cutter hub 2 is equipped with handle of a knife 1, described cutter hub 2 is cylindrical cutter body, the inside of described cutter hub 2 is cylindrical cavity, described cutter hub is provided with inhales ferromagnetic 4, the other end of described cutter hub 2 is blade 3, this design makes the utility model when drilling through pipeline, begin to pull out of hole from the periphery in the hole that will drill through, after drilling through end, the periphery of the sky that drills through is cut, the inboard has a cake waste material, avoided the drill bit of traditional structure will get into the periphery in the hole that will drill through from the center in the hole that drills through always, reduced labour intensity and to the loss of drill bit, after pipeline drills through, the ferrous waste of patty can drop out drill bit, fall in the pipeline, it is ferromagnetic that the annular suction that can move up and down in the cutter hub inboard is installed in the cylindrical cavity of cutter hub, after boring is finished, inhales the ferromagnetic absorption cake shaped steel iron waste material that takes back, prevent that waste material from dropping in the pipeline, cake waste material and the broken last waste material that stays of avoiding holing results in blockage to the transport pipeline of being holed.
Be provided with described suction ferromagnetic 4 in the cylindrical cavity of described cutter hub 2, be arranged in the described cylindrical cavity described suction is ferromagnetic, the scrap metal that boring is produced directly is adsorbed in the described cylindrical cavity, be that cavity can be used as the place of collecting waste material, more effectively avoided the obstruction of transport pipeline, also make design of the present utility model more reasonable, described blade 3 is serrated edge, as shown in Figure 3, described blade 3 has certain thickness, described blade 3 becomes ten degree angles near one side of described cutter hub 2 inboards with the one side in close described cutter hub 2 outsides, make at last what drill through, drill earlier near the pipeline of cutter hub inboard, if do not have angle, be flat, can being difficult at last last drilling of drilling through; Described handle of a knife is the regular hexagon handle of a knife of hollow, and the similar hexagonal (hexagon)nut of its shape is conveniently installed with instrument; The inner surface of described handle of a knife is provided with screw thread.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
