Abstract
The utility model relates to the field of hobs, in particular to a disc cutter ring for welding teeth. The disc cutter ring for welding the teeth comprises a ring-shaped cutter ring body, wherein a plurality of tooth grooves are formed in the outer side wall of the cutter ring body at equal intervals along the circumferential direction, an alloy block protruding out of the outer side wall is arranged in each tooth groove, and the part, where the alloy blocks do not protrude out, of the outer side wall is covered by an abrasion-resistant alloy layer. According to the disc cutter ring for welding the teeth, the abrasion-resistant alloy layer can protect the part, where the alloy blocks do not exist, of the outer side wall of the cutter ring body, and enable the outer side wall of the cutter ring body not to be prone to washout, friction and impact by quartz, grit and the like in the outside world, and therefore not only is work quality guaranteed, but also the service life of the disc cutter ring is long.
Description
Technical field

Background technology
Hobboing cutter is the instrument that is used for driving on the shield machine, and hobboing cutter generally is made of some hobboing cutter cutter rings.When hobboing cutter was worked in tempering the type stratum, the quartz and the grit that temper in the type stratum can erosion produce stronger impact force with the lateral wall of friction cutter ring main body and to lateral wall, and then destroy cutter ring, make it be difficult to use.
For the problems referred to above, along circumferentially equidistant brazing alloy piece, the abrasion resistance properties of alloy block is better at cutter ring body lateral wall for people, and hardness is higher, can resist erosion, friction and the impact of quartzy and grit.But when the quartz in tempering the type stratum and grit are more, when more quartz contacts with alloy block with grit, also can there be the part of alloy block to contact with lateral wall.Quartz and grit meeting erosion and friction lateral wall do not have the part of alloy block, and it is produced stronger impact force, the cutter ring lateral wall does not have the part of alloy block to be subject to can producing wearing and tearing after erosion, friction and the impact, cutter ring after the wearing and tearing not only work quality is lower, and the structure of the cutter ring body that constantly is worn can be more and more less, and then cause alloy block to come off, application life is shorter.
The utility model content
For the defective that exists in the prior art, the purpose of this utility model is to provide a kind of weldering tooth to apply the weldering cutter ring of disc cutter, and its abrasion resistance properties is better, and shock resistance is strong, and not only work quality is higher, and application life is longer.
For reaching above purpose, the technical scheme that the utility model is taked is: a kind of weldering tooth applies the weldering cutter ring of disc cutter, comprise circular cutter ring body, described cutter ring body lateral wall radially has some teeth groove, described some teeth groove circumferentially evenly distribute along lateral wall, be provided with evagination in each teeth groove in the alloy block of lateral wall, described lateral wall does not have the part of alloy block evagination all to be covered with wear-resistant alloy layer.
On the basis of technique scheme, the spacing between described wear-resistant alloy layer and its contiguous alloy block is 0.5mm～3.0mm.
On the basis of technique scheme, the spacing between described wear-resistant alloy layer and its contiguous alloy block is 2.0mm～3.0mm.
On the basis of technique scheme, the corresponding part with wear-resistant alloy layer of described lateral wall has groove, and described wear-resistant alloy layer applies and is welded in the groove, and the degree of depth of the groove of telling is identical with the thickness of wear-resistant alloy layer.
On the basis of technique scheme, the degree of depth of described groove is 2.0mm～5.0mm.
On the basis of technique scheme, the degree of depth of described groove is 2.0mm～3.0mm.
On the basis of technique scheme, the height of described alloy block evagination is 0.5mm～2.0mm.
On the basis of technique scheme, described wear-resistant alloy layer is mainly made by tungsten carbide.
On the basis of technique scheme, described alloy block is mainly made by carbide alloy.
On the basis of technique scheme, described lateral wall radially has 30～60 teeth groove.
The beneficial effects of the utility model are:
(1) cutter ring body lateral wall of the present utility model does not have the part of alloy block evagination all to be covered with wear-resistant alloy layer; wear-resistant alloy layer is between adjacent alloy block; wear-resistant alloy layer can protect cutter ring body lateral wall not have the part of alloy block, makes it be difficult to be subject to extraneous (for example quartz and grit) erosion, friction and impact.Therefore, safer when the cutter ring body uses, be difficult to wearing and tearing, not only work quality is better, and alloy block is difficult to come off, and application life is longer.
(2) wear-resistant alloy layer of the present utility model is mainly made by tungsten carbide, and its abrasion resistance properties is better; Alloy block is mainly made by carbide alloy, and its shock resistance is stronger.The wear-resistant alloy layer of being made by tungsten carbide and can guarantee safety and the work quality that the utility model uses by the alloy block that carbide alloy is made.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1-cutter ring body, 2-teeth groove, 3-alloy block, 4-wear-resistant alloy layer.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Referring to shown in Figure 1, the weldering tooth among the utility model embodiment applies the weldering cutter ring of disc cutter, comprises circular cutter ring body 1, and cutter ring body 1 can be assembled into cutter ring by all installing hole wherein.Cutter ring body 1 lateral wall radially has 2,36 teeth groove 2 of 36 teeth groove along the circumferentially evenly distribution of cutter ring body 1 lateral wall, alloy block 3 of each teeth groove 2 interior soldering.In order to guarantee alloy block 3 prior to external world's contact and work, alloy block 3 evaginations are in cutter ring body 1 lateral wall, and alloy block 3 evaginations are 1mm in the height of cutter ring body 1 lateral wall; Alloy block 3 is mainly made by carbide alloy.
