Description
Technical field
This utility model belongs to mine operation technical field of tools, is specifically related to the drill rod of a kind of hydraulic breaking hammer.
Background technology
As is known in the industry, drill rod is to relate to the indispensable instrument in the operation of ore deposit, and owing to drill rod belongs to attrition component, thus in the China as third place in the world big mineral products state, the usage amount of drill rod constantly increases in recent years, but also consumes substantial amounts of high-quality steel resources simultaneously.Because to hard rock ore deposit, rock and slag etc. broken time, the head of drill rod is the most quickly worn or even ruptures, can only throw away the old and change into the new, again because the material of drill rod is mostly the chrome molybdenum steel grade of high-quality, thus price is higher, as a example by the chrome molybdenum drill rod of a length of 1.2-1.5m of a diameter of 140, current price is more than 7000 yuan.In view of this, by improving the material of drill rod and simultaneously improving the structure of drill rod and can alleviate aforementioned technical problem to a certain extent.
The technical information of drill rod can be seen in disclosed Chinese patent literature, as Authorization Notice No. CN201770708U recommends there be " high-strength fan-shaped clad steel chisel ", this patent formula only sets a locating slot in the rear end of drill rod body, after the classified quenching of drill rod body, the hardness of front end is HRC50-60, and the hardness of rear end is HRC50-53(description the 0008th and 0013 section).Although this patent can cash the technique effect described in technique effect hurdle of its description to a certain extent, but there is following shortcoming: one, due to hardness and the hardness difference of rear end (i.e. pricker body) of front end (i.e. bore bit) inconspicuous, thus it is insufficient for the expection of business circles service life；Its two, although the technique that patent not mentioned drill rod body shapes, but understand it from the full text of its description especially in conjunction with schematic structure and obtain by forging, and forge that not only exist the labor intensity of workman big, and inefficient problem；Its three, have a surplus owing to the hardness of the front and back ends of drill rod body is paid close attention to by this patent, but the antiflex cracking bending resistance of afterbody attached undue importance to one thing to the neglect of the other；Its four, owing to the material of whole drill rod body is made no exception, i.e. have employed commaterial, thus be both unfavorable for reasonably economizing on resources, be also not easy to reduce cost.And for example CN204163749U is provided with " drill rod ", and this patent formula is essentially boring drill rod, i.e. belongs to drill bit category, specifically can be found in this patent specification the 0009th section.
" two metals connect drill rod from expanded joint " that the typical Authorization Notice No. CN204899809U as proposed by Chinese Shanghai castle industrial corporation introduces, drill rod body is divided into three sections and is integrally formed (description the 0027th section) by connecing from expanded joint by this patent.And this patent it is taught that head (bore bit) uses the high rigidity impact-resistant alloy steel of more than hardness HRC63, afterbody (i.e. pricker hammer, as follows) use the 35SiMn that impact strength is high, middle part (patent claims middle bar) uses the chrome-manganese-silicon steel of high intensity, specifically can be found in description the 0036th section.
Though above-mentioned CN204899809U has achievement as the material at afterbody and middle part for reducing drill rod cost using 35SiMn and chrome-manganese-silicon steel respectively, but antiflex cracking is counter-bending and anti-fragmentation performance is still fragility, and owing to using high rigidity impact-resistant alloy steel (HRC63) as the material of head, thus flintiness is still difficult to meet the expection of industry, moreover this patent does not provides the enlightenment of the concrete trade mark of high rigidity impact-resistant alloy steel, and does not provides the enlightenment that head, middle part and afterbody are prepared by what technique yet.
For above-mentioned prior art, the applicant has made positive and useful exploration, and technical scheme described below produces under this background.
