The utility model discloses bore bit is with closing gold sheet can improve welding firmness, tip wearability, practice thrift the cost.
Description
Technical field
This utility model relates to alloy material manufacturing technology field, particularly relates to a kind of bore bit alloy sheet。
Background technology
Hard alloy drill is widely used in the construction project such as mine, rock drilling, and it is easy wearing detail, again relatively costly due to hard alloy, so at work, is that hard metal tip is used in conjunction with steel main body, until hard alloy pad wear is clean。Bore bit yi word pattern on the market, cross, three blade type etc., corresponding hard alloy chip architecture is also different, costliness due to hard metal tip, the floor design of hard metal tip is become cambered surface or inverted " V " type by someone, certain cost savings effect has been also functioned in work, but but fail to reach very good effect in welding, still there will be the situation lacking the not prison weldings such as weldering, solder skip, the problem that hard metal tip directly breaks occurs time serious even at work。
Mono-line bit is by dill bit and is welded on the in-line hard metal tip of end and forms, and is widely used in the fields such as mining, quarrying, hydroelectric project, smelting。Present alloy sheet adopts in-line, and bottom is cuboid, and top crown is the R180 arc of 110 ° of basils。In use, the position of key wear is both sides and the blade of tooth crown, particularly top, when vertex abrasion to a certain extent time, use will be affected, thus entirety is scrapped。Now the bottom of alloy sheet still has substantial portion of alloy, causes unnecessary waste, after measured, when alloy sheet entirety is scrapped, throws away and retains the alloy having 70%。And hard alloy is mainly made up of tungsten powder and cobalt powder, cost is high。
Summary of the invention
In view of this, the purpose of this utility model solves above-mentioned technical problem exactly, it is provided that a kind of firm welding, tip are wear-resisting, save the bore bit alloy sheet of cost。
The present invention solves the problems referred to above by techniques below means:
A kind of bore bit alloy sheet, including alloy sheet body, and being positioned at the tip part of described alloy sheet body upper part, described tip part includes pointed nose and bottom, the cross-sectional width of described bottom is more than the cross-sectional width of described alloy sheet body, and described bottom is connected with described alloy sheet body。
Further, described alloy sheet body and described tip part are one-body molded。
Further, described alloy sheet body is cuboid, and the length of described tip part is equal with the length of described alloy sheet body, and the cross section of described tip part is umbrella shape。
Further, described alloy sheet body is cuboid, the length of described tip part is equal with the length of described cuboid, and the cross section of described tip part includes top curve and states, with institute top, the first limit and the second limit that arc two ends are connected, and connects described first limit and the base on described second limit。
Further, the width of described alloy sheet body is 1/4th of described base length。
Further, described top curve correspondence central angle is 30 ° ~ 70 °。
Preferably, described top curve correspondence central angle is 50 °。
Further, the length on described base is 15mm, and the width of described alloy sheet body is 5mm, and the length of described alloy sheet body is 18mm。
Further, described this lamellar body of alloy is cuboid, and the length of described tip part is equal with the length of described alloy sheet body, and the cross section of described tip part is triangle。
Further, the both sides of described tip part are provided with wearing layer。
Bore bit alloy sheet of the present utility model, including alloy sheet body, and being positioned at the tip part of described alloy sheet body upper part, described tip part includes pointed nose and bottom, the cross-sectional width of described bottom is more than the cross-sectional width of described alloy sheet body, and described bottom is connected with described alloy sheet body。Compared with prior art, effectively preventing breaking of bore bit alloy sheet, firm welding, and save material cost, further, tip part two sides are provided with wearing layer, improve work efficiency and extend the service life of bore bit alloy sheet。
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of bore bit alloy sheet of this utility model；
1-alloy sheet body, 2-tip part, 21-pointed nose, bottom 22-, 31-top curve, 32-the first limit, 33-the second limit, 34-base。
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments。Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。
Referring to Fig. 1, it it is the structural representation of a kind of bore bit alloy sheet that this utility model embodiment provides, described bore bit alloy sheet includes alloy sheet body 1, with the tip part 2 being positioned at described alloy sheet body 1 top, described tip part 2 includes pointed nose 21 and bottom 22, the cross-sectional width of described bottom 22 is more than the cross-sectional width of described alloy sheet body 1, and described bottom 22 is connected with described alloy sheet body 1。Preferably, described alloy sheet body 1 is one-body molded with described tip part 2。
