Abstract
The utility model discloses a novel hobbing cutter of a shield machine, which comprises a hobbing cutter body and one or two cutter rings arranged on the hobbing cutter body, wherein the width of the cutting edge of the cutter ring is 26 mm. Since the width of the cutting edge of the cutter ring amounts 26 mm, the hobbing cutter of the shield machine has high compression strength and good wear resistance and impact resistance, the rocks in the bottom layer of pebbles and large grain-size float rocks can be effectively cut into pieces, and the effective and stable driving of the shield machine is realized; and in addition, the 4Cr5mosiv1 alloy steel is used at the cutter ring part, and the cutter ring has good surface hardness and tensile strength after heat treatment, therefore, the novel hobbing cutter has better wear resistance and impact resistance and can effectively prevent the cutting edge of the hobbing cutter from being damaged due to transient vibration and impact.
Description
Technical field
The utility model relates to the shield machine that a kind of tunnel excavation uses, and particularly relates to the hobboing cutter in a kind of shield machine.
Background technology
Hobboing cutter is meant not only and rotates with cutterhead, also makes the moving cutter of autorotation simultaneously.Hobboing cutter can be divided into profile of tooth hobboing cutter and disk cutter according to the shape of blade.At present, shield machine roller cutter mainly is a disk cutter, and disk cutter has the branch of single-blade, twolip and multiple-cutting-edge.During work, the drive hobboing cutter of cutterhead under whirligig drives be around the revolution of cutterhead central axis, and each hobboing cutter also around separately cutter shaft rotation, makes hobboing cutter roll extrusion continuously on soil body face simultaneously, makes soil body fragmentation cut by hobboing cutter to the extruding and the shearing of the soil body.
When shield machine when containing high strength cobble, big particle diameter erratic boulder stratum middle and long distance driving easily slide because cobble intensity is high, be difficult to directly be shredded by cutter, it is higher therefore wear-resistant the and anti-impact of cutter to be clashed into Capability Requirement.Traditional hobboing cutter is because structure design aspect existing problems cause the abrasion resistance of hobboing cutter relatively poor, and the tool changing driving distance is shorter, number of changing knife is more, therefore the shield cutter expense cost is higher, drivage efficiency is low, if meet when formation condition is bad can't to advance the cabin tool changing, even can't tunnel fully.
The utility model content
For addressing the above problem, the utility model provides that a kind of abrasion resistance is good, the New Kind of Hob of impact resistance, and it can effectively shred rock in cobble and big particle diameter waft the stone bottom, realize efficient, the stable driving of shield machine.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of novel shield machine roller cutter comprises hobboing cutter main body and one or two cutter ring that is arranged on this main body, and the blade width of described cutter ring is 26mm.
As improvement of the technical scheme, described cutter ring is made by the 4Cr5mosiv1 alloy steel.
As further improvement in the technical proposal, the hardness of described cutter ring is HRC56-60.
As further improvement in the technical proposal, the tensile strength of described cutter ring is 2000Mpa.
The beneficial effects of the utility model: because shield machine roller cutter of the present utility model, the width of the knife edge part of its cutter ring reaches 26mm, the compressive strength height, have good abrasion resistance and impact resistance, it can effectively shred rock in cobble wafts the stone bottom with big particle diameter, realize efficient, the stable driving of shield machine.
In addition, cutter ring of the present utility model partly uses the KDCMSV special steel, has good case hardness and tensile strength after Overheating Treatment, therefore, has better wear resistance and impact resistance, can prevent effectively that transient vibration and impact from causing damage to the hobboing cutter blade.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
The specific embodiment
With reference to Fig. 1, a kind of novel shield machine roller cutter of the present utility model comprises hobboing cutter main body 1 and one or two cutter ring 2 that is arranged on this main body 1, and blade 21 width of described cutter ring 2 are 26mm.Because shield machine roller cutter of the present utility model, the width of blade 21 parts of its cutter ring 2 reaches 26mm, and the compressive strength height has good abrasion resistance and impact resistance, it can effectively shred rock in cobble wafts the stone bottom with big particle diameter, realize efficient, the stable driving of shield machine.
As preferred embodiment, described cutter ring 2 is made by the 4Cr5mosiv1 alloy steel.It can reach HRC56-60 through vacuum heat rear surface hardness, tensile strength can be up to 2000Mpa, be higher than common alloy steel far away, what be the utlity model has better wear resistance and impact resistance, can effectively prevent transient vibration and impacts the hobboing cutter blade is caused damage.
In addition, hobboing cutter moment of torsion of the present utility model is 30～35N/m.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
