Abstract
The utility mode relates to electric tools, in particular to an alloy tool steel bit. The lengthened alloy tool steel bit comprises an alloy auger bit, an outer threaded section and a connecting piece, wherein the outer threaded section is fixed with the tail part of the auger bit coaxially by welding; one end of the connecting piece is provided with an inner threaded hole matched with the outer threaded section in a threaded manner, and the inner threaded hole is connected with the outer threaded section; and the other end of the connecting piece is hexagonal so as to be connected with a connecting head of the drill. The alloy tool steel bit provided by the utility model has excellent rigid, convenience in manufacture, and low cost.
Description
Technical field
The utility model relates to electric tool, relates in particular to a kind of alloy tool steel bit.
Background technology
COREX gasification smelting furnace generally need be installed hundreds of thermocouples, and these thermocouples comprise the wall muscle thermocouple of some, and the mounting means of this thermocouple is more special, with other thermocouple remarkable difference is arranged.A difference is thermocouple not to be set in the graphite jointing medium between the body of heater cooling wall in advance protection tube is installed, and another difference is that the installation of thermocouple is that refractory brick carries out after building completion by laying bricks or stones in stove.After this just needs stove such as instrument specialty to construct the jointing between the cooling wall, adopt the method for machine drilling on graphite packing and graphite carbon brick, to come outbreak out installing hole respectively, and then carry out the installation of thermocouple.
Whole engineering is smash at graphite respectively and is holed on the material hundreds of, and boring is over one hundred on the graphite carbon brick.Drilling depth cooling wall in the stove gos deep into 0.25-0.5 rice, aperture 16mm toward the stove center position.Need 4 of L=800mm alloy tool steel bits, 5 on L=1050mm drill bit for reaching requirement.
So just bring several problems:
If 1 adopts the inlet extension alloy tool steel bit; So every price about 90,000; This just causes the too high words from 9 drill bits of external disposable purchase of installation cost need increase installation cost more than 80 ten thousand, possibly also will purchase in addition and corresponding special electric drill of drill bit and impact electric hammer.
2, prolong the duration from external import drill bit and facility, the whole duration is exerted an influence.
3, inconvenient site operation is because field condition is complicated, and construction location is narrow.The flange short tube internal diameter of installation thermocouple is Φ 32 mm only, and 1 meter long drill bit is goed deep into flange short tube and passed furnace wall, grout blanket, the boring of cooling wall arrival graphite brick, is easy to the more crisp long drill bit switch out of rigidity.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and a kind of lengthening alloy tool steel bit is provided.The drill bit rigidity of the utility model is good, easy to make, with low cost.
The utility model is achieved in that a kind of lengthening alloy tool steel bit, and it comprises the alloy spiral bit, and it also comprises:
One external thread section, it is fixed with spiral bit afterbody coaxial welding;
A connector, its end are provided with the internal thread hole with external thread section screw thread coupling, and link together with external thread section, the other end have for hexagonal profile to connect the rig connector.
The utility model is practiced thrift installation cost and is adopted homemade common alloy bit to come processing and fabricating, and cost is every 100 yuan, well below inlet extension type drill bit; Not influencing the duration carries out field fabrication extended type drill bit at once, does not delay the duration; Raise labour efficiency and make things convenient for the different situations of site operation, the drill bit of processing variety classes and length, greatly convenient construction according to the scene.
Description of drawings
Below, in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model sketch map.
The specific embodiment:
As shown in the figure, a kind of lengthening alloy tool steel bit, it comprises alloy spiral bit 1, it also comprises:
One external thread section 2, it is fixed with said spiral bit 1 afterbody coaxial welding;
A connector 3, its end are provided with the internal thread hole with external thread section 2 screw threads couplings, and link together with external thread section 2, the other end have for hexagonal profile to connect rig connector 4.
Claims (1)
1. lengthening alloy tool steel bit, it comprises the alloy spiral bit, it is characterized in that, it also comprises:
One external thread section, it is fixed with spiral bit afterbody coaxial welding;
A connector, its end are provided with the internal thread hole with external thread section screw thread coupling, and link together with external thread section, the other end have for hexagonal profile to connect the rig connector.
