Abstract
The utility model discloses a shell type drill shank, which comprises a drill shank body. Different from the prior art, the shell type drill shank is also provided with a bit shank connected with the drill shank body, wherein the drill shank body consists of a drill shank and same or different conical bodies arranged on both sides of the drill shank; the outside of one end of the bit shank is provided with a shank collar with a bulge loop, and the inside is provided with a tapered hole matched with the conical bodies of one end of the drill shank body; the conical bodies of one end of the drill shank body are inserted into the tapered hole of the bit shank to be fixedly connected into a whole; and the other end of the bit shank is connected with a charge. The shell type drill shank has long service life, low manufacture cost and convenient use.
Description
Technical field
The utility model relates to drill steel, specifically is a kind of shell type drill steel.
Background technology
Present hammer drill drill steel is that shank collar (forge hot bulge loop) and drill steel are combined as a whole, in use, because the piston of hammer drill constantly clashes into the afterbody of drill steel, make the bit shank distortion, be the anti-sticking pricker, to polish to bit shank, when bit shank was polished to a certain degree, shank collar will be run into the head of hammer drill, at this moment just can not use again, whole drill steel also can only be scrapped, and this is a waste greatly to the steel resource.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of shell type drill steel of easy to use, low cost of manufacture is provided.
The technical scheme that realizes above-mentioned purpose is:
A kind of shell type drill steel comprises the drill steel body, unlike the prior art be: also be provided with the lugs that is connected with the drill steel body, described drill steel body is made up of the drill steel bullet identical or inequality with being arranged on the drill steel two ends, one end outer setting of described lugs has the shank collar of band bulge loop, inside is provided with the bellmouth with drill steel body one end toper body coupling, be fixed with one in the bellmouth of the bullet insertion lugs of drill steel body one end, the other end of lugs is connected with hammer drill.
Described lugs length＞105mm～150mm can select for use impact-resistant material to make.
Described drill steel body and lugs are hollow stem.
During work, bore bit is fitted on the bullet of drill steel body away from an end of lugs, lugs is not established an end of bellmouth and hammer drill is equipped gets final product, when the bit shank in using is out of shape, as long as the drill steel body is taken off, bit shank is machined to the length of requirement, also can continue to enable.
The utility model has the advantages that:
1, the drill steel body can use for a long time, needn't whole scraps, and has correspondingly improved the life-span of drill steel, for the user reduces the running cost that drill steel consumes;
2, because the utilization rate of drill steel body realizes significantly improving, reduced the excess waste of rock drilling industry, the reform of a success at last aspect recycling economy to the steel resource;
3, the client scraps drill steel on hand bit shank is carried out the tapering that machine is added to cone, can also enable, and should not handle by scrap iron, and saving has realized turning waste into wealth;
4, the low cost of manufacture of drill steel body is crossed the cost of former drill steel, for the steel industry, has also reduced manufacturing cost;
5,, reduce the bit shank distortion effectively, the application life of improving lugs because the utility model lugs material can be selected the material that is more suitable for for use;
6, the utility model lugs also can select for use cheaper material to make, with the purpose (preserving the drill steel of high value to change low value shell type drill steel) that realizes throwing a sprat to catch a herring;
7, the also available steel pipe of drill steel body of the present utility model adds two ends bullet be combined into, fully reduces consumption and use cost to steel.
Description of drawings
Fig. 1 is the structural representation of the utility model shell type drill steel.
The specific embodiment
As shown in Figure 1, shell type drill steel of the present utility model is made up of drill steel body 1 and lugs 2, drill steel body 1 is a hollow stem, it is 7-12 ° bullet 4 that tapering is arranged at two ends, lugs 2 also is a hollow stem, an its termination outer setting becomes the shank collar 5 of band bulge loop, inside is provided with the bellmouth 3 that the bullet 4 with drill steel body 1 termination is complementary, the bullet 4 of drill steel body 1 one ends inserts to tighten up in the bellmouth 3 and connects as one, described drill steel body 1 is made by YB2003-78 hollow hexagonal bar material, and lugs is made by 35SiMnMoV or 40CrMnMo material.
The drill steel of drill steel body 1 is made by round steel pipe, and the round steel pipe termination is equipped with bullet 4, and all the other are with embodiment 1.
Claims (2)
1. shell type drill steel, comprise the drill steel body, it is characterized in that: also be provided with the lugs that is connected with the drill steel body, described drill steel body is made up of the drill steel bullet identical or inequality with being arranged on the drill steel two ends, one end outer setting of described lugs has the shank collar of band bulge loop, inside is provided with the bellmouth with drill steel body one end toper body coupling, is fixed with one in the bellmouth of the bullet insertion lugs of drill steel body one end, and the other end of lugs is connected with hammer drill.
2. shell type drill steel according to claim 1 is characterized in that: described lugs length＞105mm～150mm.
