Abstract
A kind of helical teeth cutter ring of disc cutter, relate to shield structure hobboing cutter field, cutter ring matrix is hollow cylinder, cutter ring matrix is radially evenly offered some teeth groove, teeth groove opening outwardly, in each teeth groove, be provided with a hard alloy blocks, the angle between the center line of teeth groove opening and the axis of cutter ring matrix is 0～45 °; Hard alloy blocks is L-type, and a limit of hard alloy blocks embeds in teeth groove, and another limit is covered in the excircle of cutter ring matrix.The overall wear resistance of the utility model hobboing cutter cutter ring is good, long service life.
Description
Technical field
The utility model relates to shield structure hobboing cutter field, is specifically related to a kind of helical teeth cutter ring of disc cutter.
Background technology
Hobboing cutter is the instrument of fractured rock in shield machine driving, and hobboing cutter cutter ring is the parts that directly contact with rock in hobboing cutter.Hobboing cutter when driving, directly wearing and tearing of rock, impact excircle and the both ends of the surface of cutter ring, thereby cutter ring external diameter is reduced, lose cutting effect and scrap.
For the problems referred to above, people are at the some hard alloy blocks of cutter ring matrix excircle soldering, and at excircle surfacing wearing layer, during cutter ring work, and rock wear and tear hard alloy blocks, wearing layer and cutter ring matrix simultaneously.The hardness of hard alloy blocks is high, abrasion resistance properties is better, be described as " industrial tooth ", the abrasion resistance of wearing layer and cutter ring matrix is more a lot of than wearing no resistance of hard alloy blocks, rock is abrasion wearing layer and cutter ring matrix fast, thereby the part that makes hard alloy blocks be brazed in teeth groove reduces, and the part of exposing cutter ring matrix increases, cause hard alloy blocks easily to fracture, even come off, and whole cutter ring was lost efficacy, application life is short.
Utility model content
For the defect existing in prior art, the purpose of this utility model is to provide a kind of helical teeth cutter ring of disc cutter, and its overall wear resistance is good, long service life.
For reaching above object, the technical scheme that the utility model is taked is: a kind of helical teeth cutter ring of disc cutter, comprise cutter ring matrix, cutter ring matrix is hollow cylinder, described cutter ring matrix is radially evenly offered some teeth groove, teeth groove opening, is provided with a hard alloy blocks outwardly in each teeth groove, the angle between the center line of described teeth groove opening and the axis of cutter ring matrix is 0～45 °; Described hard alloy blocks is L-type, and a limit of hard alloy blocks embeds in teeth groove, and another limit is covered in the excircle of cutter ring matrix.
On the basis of technique scheme, described cutter ring matrix is made by low-carbon alloy structural steel.
On the basis of technique scheme, described hard alloy blocks is made by Talide.
On the basis of technique scheme, each of described hard alloy blocks seamed edge is through chamfered.
On the basis of technique scheme, each hard alloy blocks is brazed in corresponding teeth groove.
On the basis of technique scheme, the part that the excircle of cutter ring matrix is not covered by hard alloy blocks is provided with wearing layer, and the thickness of wearing layer is identical with the thickness of hard alloy blocks that is covered in cutter ring matrix excircle.
On the basis of technique scheme, the thickness that is covered in the wearing layer of cutter ring matrix excircle is 3mm.
On the basis of technique scheme, the end face of described cutter ring matrix is coated with coating rubbing-layer, and wearing layer is arranged at around teeth groove.
On the basis of technique scheme, described wearing layer is made by tungsten carbide.
The beneficial effects of the utility model are:
1, the angle between the opening center line of teeth groove of the present utility model and the axis of cutter ring matrix is 0～45 °, each hard alloy blocks oblique cutting enters cutter ring matrix, therefore the fitting area of hard alloy blocks and cutter ring matrix is large, thereby make both soldering strengths high, reduce the hard alloy blocks probability that comes off, long service life.
2, hard alloy blocks of the present utility model is L-type; a limit of hard alloy blocks embeds in teeth groove, and another limit is covered in the excircle of cutter ring matrix, and the protected area of hard alloy blocks tool setting cycle basis body is large; overall wear resistance is good, thereby extends whole cutter ring application life.
3, the part that the excircle of cutter ring matrix of the present utility model is not covered by hard alloy blocks is provided with wearing layer; although the abrasion resistance of wearing layer is poorer than hard alloy blocks; but better than cutter ring matrix; thereby make cutter ring matrix under the duplicate protection of hard alloy blocks and wearing layer; within the longer time, opposing is worn and torn, thereby guarantees the application life of whole cutter ring.
