Abstract
The present invention provides a dry hollow diamond drill bit which is suitable for drilling holes on walls in building construction, house reformation, pipe laying and municipal construction and is also suitable for building quality supervision units to sample. Alloy drilling teeth with certain abrasive resistance are welded at the lower end of a drill body, and are covered with a diamond. A drill stock is welded at the upper end of the drill body. Chip removal holes and chip removal ridges are arranged around the drill body. The drill teeth are in circular thin-wall section tooth shapes. The present invention solves the problems of dust blockage and difficult chip removal in drilling, and thus, the solid waste materials in the hollow thin-walled cavity of the drill body are conveniently unloaded. The drill stock forms a triangle shape, and has high universality.
Description
The present invention relates to a kind of drill bit, particularly a kind of is the dry hollow diamond drilling bit of the diamond insert of feature with the profile of tooth wear resisting part.It is applicable to construction, building reconstruction, and the usefulness of the wall boring in the construction such as vapour, water, oil system pipeline laying and urban construction also can be for the usefulness of construction quality supervision unit sample.
CN2031348U discloses a kind of precast reinforced concrete spare and has processed serial sleeve brill, and its bit part is the hard cutting material of welding, drill body hollow.Its weak point is a chip removal difficulty when the dry type drilling.In order to reach the purpose of chip removal, when drilling, need inject and cool off but liquid.
A kind of light and flexible that the drilling tool that the objective of the invention is to fall behind at industries such as China's buildings is developed, the dry hollow diamond drilling bit that rate of penetration is fast and drilling quality is high.Wall plastering and gunite work finish during general pipeline construction, use the water hammer drill bits obviously inapplicable in the case, especially to the skyscraper drilling construction, as use the water under high pressure drill to consider to be worth doing, to bring great difficulty to construction, the invention solves drill bit problem of water chip removal not when creeping into for this reason, but make dry hollow diamond drilling bit not be subjected to all normal constructions of any external condition restriction.
The present invention is achieved in that dry hollow diamond drilling bit is by boring tooth 1, drill body 3, turnbuckle 5, drillstock 6 compositions.The lower end of drill body 3 is being welded certain wearability alloy and is being plated adamantine brill tooth 1, and it has certain wearability, make it to creep into sharp, stable performance, it is little that drill bit consumes, the drilling quality height.Drillstock 6 is being welded in the upper end of drill body 3, and turnbuckle 5 is arranged on the drillstock 6, around the drill body 3 chip-removal hole 2 and chip removal crest line 4 is arranged, and drill body 3 is the hollow thin-wall cavity.
The present invention can be achieved in that also boring tooth 1 is annular thin-walled nodular, and this design is laborsaving, the saving of labor, save time, and can reduce most of area of cut and workload, and resistance is little when creeping into, and chip removal is fast.Chip-removal hole 2 around the drill body 3 be shaped as oblique slotted hole, to realize the inner break flour of cleaning, be convenient to the real core waste material in the removal drill body 3 hollow thin-wall cavitys.Chip removal crest line 4 is the spiral crest line of projection, and it has solved drill bit break flour when creeping into and has stopped up the problem of chip removal difficulty.Drillstock 6 be shaped as triangle, be convenient to install and use with common electric hand drill, make it to prevent loosening relatively.
Good effect of the present invention is:
1. can bore the hole than the big 3-5mm of diameter of steel tube on wall, it is low to shake little noise during punching, the drilling quality height, and wall need not be repaired and surface treatment behind the pipeline construction.
2. creep into sharply, resistance is little, and chip removal is rapid, can bore hole at any angle, highly versatile on wall.
3. bit life is long, high efficiency.Making a call to a hole in past 0.5-1 hour, and used the dry hollow diamond drilling bit punching now, can punch in one minute, is 30-50 times of the sort of drilling tool in the past.
The present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a shape and structure schematic diagram of the present invention.
Fig. 2 is a upward view of the present invention.
Fig. 3 is the cutaway view of drill body 3 of the present invention.
Fig. 4 is the cutaway view of drillstock 6 of the present invention.
Wherein:
1. bore tooth 2. chip-removal holes
3. drill body 4. chip removal crest lines
5. turnbuckle 6. drillstocks
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.During use, drillstock 6 is stuck on the chuck of electric hand drill, connects power supply, holed in the position of desire boring.Because the lower end of drill body 3 is being welded the alloy of certain wearability and is being plated adamantine brill tooth 1, bore the circular thin-walled joint of being shaped as of tooth 1 dentation, wall thickness 4mm, so cutting is sharp when creeping into, resistance is little, make it to bring into play its advantage that has to satisfy the engineering construction requirement, efficient is 30-50 times of artificial punching in the past.Chip-removal hole 2 and chip removal crest line 4 around the drill body 3 are the spiral crest line of oblique slotted hole and projection, solved when drill bit creeps into can only the water chip removal problem.So resistance is little when using dry type diamond hollow boring bit to creep into, chip removal is fast, is convenient to clear up inner break flour, is convenient to the real core waste material in the removal drill body 3 hollow thin-wall cavitys.Drillstock 6 be shaped as triangle, be convenient to install and use with common electric hand drill, make it to prevent loosening relatively.The length of drill body 3 can be 300mm, can bore general wall (being 250-270mm behind the general wall plastering).Dry hollow diamond drilling bit can be holed on any hard brittle materia, for bringing into play its abundant advantage, make it to be applied to every field, turnbuckle 5 is arranged on the drillstock 6, it and the supporting use of fixed bracket can make the present invention to other construction material drilling constructions such as rock, pottery, granite, marble, concrete.
