Abstract
The utility model relates to a cutter ring of disc cutter for shield machine, which comprises a cutter ring body and a cutter ring periphery, wherein tooth grooves are machined on the cutter ring periphery to form cutting teeth. Wear resistant alloy layer is welded on the tooth surface of cutting teeth in deposition manner. The cutter ring of disc cutter has the beneficial effects that: 1. cutting teeth are arranged on the cutter ring periphery to change the structure of the cutter ring periphery so that the cutter ring can have strong excavation force on rock and replace the impact force of alloy teeth and extruding force of naked cutter ring in prior art, when the cutter disc rotates, the sharp edge of cutting teeth cuts into the rock and excavate rock from rock formation to realize high speed cut driving so that the rock broken efficiency of cutter ring of disc cutter in soft geological rock formation is effectively improved; 2. wear resistant alloy layer is welded on the tooth surface of the cutting teeth so that the wear resistance and impact resistance are improved and the service life of cutter ring of disc cutter is prolonged.
Description
Technical field
The utility model relates to a kind of disk cutter cutter ring that is used for shield machine, is the improvement to existing disk cutter cutter ring.
Background technology
Hobboing cutter is to be used to the instrument that tunnels on the shield machine, hobboing cutter is made of some hobboing cutter cutter rings, existing disk cutter cutter ring has two kinds on inserted and naked circle type, as Chinese patent CN201074516Y, provide a kind of on the external circumference of cutter ring the hobboing cutter cutter ring of setting-in hard alloy blocks, to strengthen the cutter ring abrasion resistance and to increase application life.Impact force and extruding force fractured rock that they produce when relying on the hobboing cutter rotation to advance, be applicable to driving than hard rock, but its advantage performance was not come out when the hobboing cutter cutter ring of above-mentioned existing structure ran into than soft formation, carbide button and cutter ring are wrapped up by soft mudstone easily, driving speed is obviously slack-off, and work efficiency reduces.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and provides a kind of and can realize in the hag homogenous rock stratum that high-speed cutting tunnels, effectively improves the disk cutter cutter ring of efficiency of breaking rock.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include cutter ring body and cutter ring outer rim, its difference is to form cutting teeth by offering teeth groove on described cutter ring outer rim.
Press such scheme, described cutting teeth to uniform, makes the cutter ring outer rim be the wheel dentation along the cutter ring outer circumference.
Press such scheme, apply the weldering wear-resistant alloy layer at the cutting teeth flank of tooth; Described wear-resistant alloy layer is the carbine abrasion-proof alloy-layer; Described antifriction alloy layer thickness is 2.0～5.0mm.
Press such scheme, described cutting teeth tooth depth is 15～35mm; Described cutting teeth tooth angle B is 30 °～45 °, and radial section injection angle α is 15 °～25 °.
The beneficial effects of the utility model are: 1, in the cutter ring outer rim cutting teeth is set, changed cutter ring outer rim structure, make it when work, produce very strong digging force to rock, with the impact force that replaces existing carbide button and the extruding force of naked cutter ring, the sharp edge of cutting teeth is cut rock and it is excavated the disengaging rock stratum during cutterhead rotation, realize incision driving at a high speed, effectively improved the efficiency of breaking rock of hobboing cutter cutter ring in the hag homogenous rock stratum; 2, apply the wear-resistant and shock resistance that the weldering wear-resistant alloy layer can significantly improve cutting teeth at the cutting teeth flank of tooth, prolong the application life of hobboing cutter cutter ring.
