Abstract
Improve Novel hobbing cutter of shield machine cutter ring, including hobboing cutter cutter ring body, hobboing cutter cutter ring body is round pie, and center is provided with installing hole, the whole circle of blade outer circumference surface at hobboing cutter cutter ring gathers uniformly and is provided with some undercuts, and described undercut is in tilted layout relative to hobboing cutter cutter ring body central axis；Blade periphery is provided with the nitriding groove through Nitrizing Treatment.Under not changing integrally-built form, increase the cutter ring extruding force to rock, reduce the thrust of cutterhead, strengthen the wearability of cutter ring, accelerate the broken speed of rock, and reduce cost, reduce the construction time limit.The setting of undercut increases the cutter ring blade pressure force to rock, the most not only reduces the thrust of scuta machine knife dish but also improve calculifragous efficiency.The setting of nitriding groove adds the wear-resisting intensity of hobboing cutter blade, improves production efficiency high, reduces again production cost.
Description
Technical field
This utility model relates to hobboing cutter technical field, particularly to a kind of hobboing cutter cutter ring on shield machine, belongs to matching appliances on underground engineering, subway, tunnel, excavating equipment.
Background technology
Shield machine is mainly used in underground engineering, subway work digging, is also used for the constructing tunnels such as highway, railway, hydroelectric project, on cutter head of shield machine, main installation hobboing cutter and scraper are dug, and hobboing cutter is mainly applied to hard rock, is arranged on cutterhead, rotation along with cutterhead, on the one hand revolve round the sun with cutterhead, on the one hand rotation, and in cutterhead thrust, rock face is compressed under moment of torsion effect, when thrust exceedes the intensity of rock, the rock of hobboing cutter cutter ring rolled portion directly crushes, and forms carg and avalanche.The most practical hobboing cutter cutter ring extruding blade all uses plane to extrude form, so form cutterhead thrust big, and it is high to crush difficulty, therefore cause cutterhead propulsive efficiency low, the engineering time limit is long, and both construction costs was high, especially hard formation causes the biggest difficulty to unit in charge of construction, there is again embedded alloy form in market now, but cost is the highest, and unit in charge of construction cannot accept.
Utility model content
For overcoming problems of the prior art, this utility model provides a kind of improvement Novel hobbing cutter of shield machine cutter ring, under not changing integrally-built form, increase the cutter ring extruding force to rock, reduce the thrust of cutterhead, strengthen the wearability of cutter ring, accelerate the broken speed of rock, and reduce cost, reduce the construction time limit.
The technical scheme in the invention for solving the technical problem is: this kind improves Novel hobbing cutter of shield machine cutter ring, including hobboing cutter cutter ring body, hobboing cutter cutter ring body is round pie, center is provided with installing hole, the whole circle of blade outer circumference surface at hobboing cutter cutter ring gathers uniformly and is provided with some undercuts, and described undercut is in tilted layout relative to hobboing cutter cutter ring body central axis；Blade periphery is provided with the nitriding groove through Nitrizing Treatment.
Further, the cross section of described undercut is rectangle.
Further, in described undercut, adjacent two undercuts are 10 degree along hobboing cutter cutter ring body interval angles A.
Further, the angle of inclination B of described undercut is 35 degree to 45 degree.
To sum up, the having the beneficial effect that of technique scheme of the present utility model:
Under not changing integrally-built form, increase the cutter ring extruding force to rock, reduce the thrust of cutterhead, strengthen the wearability of cutter ring, accelerate the broken speed of rock, and reduce cost, reduce the construction time limit.
The setting of undercut increases the cutter ring blade pressure force to rock, the most not only reduces the thrust of scuta machine knife dish but also improve calculifragous efficiency.
The setting of nitriding groove adds the wear-resisting intensity of hobboing cutter blade, improves production efficiency high, reduces again production cost.
Accompanying drawing explanation
Fig. 1 is half sectional view of the present utility model；
Fig. 2 is top view of the present utility model.
In figure:
1 hobboing cutter cutter ring body, 2 installing holes, 3 undercuts, 4 nitriding grooves, 5 interval angles A, 6 angle of inclination B.
Detailed description of the invention
Being described in detail feature of the present utility model and principle below in conjunction with accompanying drawing, illustrated embodiment is only used for explaining this utility model, not limits protection domain of the present utility model with this.
As depicted in figs. 1 and 2, this utility model includes that hobboing cutter cutter ring body 1, hobboing cutter cutter ring body are round pie, and center is provided with installing hole 2.The whole circle of blade outer circumference surface at hobboing cutter cutter ring gathers uniformly and is provided with some undercuts 3, and described undercut is in tilted layout relative to hobboing cutter cutter ring body central axis.To increase the cutter ring blade pressure force to rock, the most not only reduce the thrust of scuta machine knife dish but also improve calculifragous efficiency.
Blade periphery is provided with the nitriding groove 4 through Nitrizing Treatment, adds the wear-resisting intensity of hobboing cutter blade, improve production efficiency high, reduce again production cost relative to embedded alloy form.
The cross section of described undercut is rectangle, in time by squeeze broken after rock discharge, prevent rock squeeze broken after get lodged in and affect crushing efficiency and effect in undercut.
Described adjacent undercut is 10 degree along hobboing cutter cutter ring body interval angles A5, and the angle of inclination B6 of described undercut is 35 degree to 45 degree, has both ensured that crushing efficiency also ensured cutter ring intensity.
Above-described embodiment is only the description carrying out preferred implementation of the present utility model; not the scope of the present invention is defined; on the premise of without departing from this utility model design spirit; relevant technical staff in the field, to various deformation of the present utility model and improvement, all should expand in protection domain determined by this utility model claims.
