Abstract
The invention discloses a cutting blade structure of a shield machine. The structure comprises a cutter body and a blade which is arranged on the front part of the cutter body, and is characterized in that: the cutter body is provided with a wear-resistant overlaying layer which is made of hard alloy powder; the thickness of the wear-resistant overlaying layer is between 3 and 5 millimeters; and the cutter body is made of high-intensity low-alloy steel. In the structure, the cutter body is provided with the wear-resistant overlaying layer, so that sand, stones and the like from any direction are prevented from wearing the cutter body and the service life of a cutter is prolonged; the cutter body is made of the high-intensity low-alloy steel, and the blade is made of a hard alloy and welded by braze welding, so that the structure is stable and has a high wear-resistant degree; simultaneously, the blade replacement frequency is reduced in the construction process, so that construction cost is lowered and a construction progress is accelerated. The invention has the advantages that: the cutting blade structure has a simple structure, high stability and attractive appearance, is convenient to use and is worthy of popularization.
Description
Technical field
What the present invention relates to is device architecture on a kind of shield machine, and what be specifically related to is a kind of cutting tool structure of shield machine.
Background technology
Shield machine, full name is the shield tunnel development machine, be a kind of special engineering machinery of tunnel piercing, modern shield excavation machine light harvesting, mechanical, electrical, liquid, sensing, information technology are in one, have functions such as the excavation cutting soil body, conveying soil quarrel, assembly unit tunnel lining, the correction of measurement guiding, relate to multi-door subject technologies such as geology, building, machinery, mechanics, hydraulic pressure, electric, control, measurement, and to carry out manufacturing and designing of " cutting the garment according to the figure " formula according to different geology, reliability requirement is high.Shield excavation machine has been widely used in construction of tunnel such as subway, railway, highway, municipal administration, water power.
Along with the development of China's urban construction, underground constructions such as underground rail traffic, cross-river tunnel increase day by day, and the shield structure advance distance in tunnel is also more and more longer.But shield machine is after advancing continuously through long distance, depend primarily on the life-span of cutting tip its application life, existing its scuff resistance of shield machine blade is not enough, the soil body is very fast to the wearing and tearing of wing, after it may wear to a certain degree, the soil body will the cutter hub of knife face bottom weares and teares behind the scraper to being positioned at, and therefore long-term use makes the blade infringement easily, even influence time limit of engineering, cause unnecessary economic loss.
Summary of the invention
At the deficiency that exists on the prior art, the present invention seeks to have improved the efficient of shield-tunneling construction in the cutting tip structure that a kind of wear-resistant, shield machine of prolonging blade application life is provided, save engineering cost.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of cutting tool structure of shield machine, the blade that it comprises cutter hub and is arranged on the cutter hub front portion, it is characterized in that, described cutter hub is provided with the wearable overlay that cemented carbide powder is made, avoid the wearing and tearing of cutter hub, described hardfacing layer thickness is 3～5mm, and what described cutter hub material adopted is Aldecor.
According to the cutting tool structure of above-mentioned shield machine, wherein, described wearable overlay is fixed on the cutter hub by digital controlling plasma powder spray welding apparatus.
According to the cutting tool structure of above-mentioned shield machine, wherein, described cutter hub adopts the Aldecor material.
According to the cutting tool structure of above-mentioned shield machine, wherein, what described blade adopted is carbide chip, adopts the soldering welding fixing between carbide cutter tool and the cutter hub, increases steadiness.
The present invention has prevented the sand of any direction by one deck wearable overlay is set on cutter hub, stone etc. have prolonged the application life of blade to the wearing and tearing of cutter hub; And cutter hub employing Aldecor, blade adopts carbide alloy, and by the soldering welding, its Stability Analysis of Structures, the rub proofness height simultaneously, in the work progress, reduces the replacing of blade, has reduced construction cost, has accelerated construction speed; It has simple in structure, easy to use, and stability is high, and the advantage of beautiful appearance is worthy of popularization.
Description of drawings

The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
Embodiment:
The cutting tool structure of a kind of shield machine of present embodiment, the blade 2 that it comprises cutter hub 1 and is arranged on cutter hub 1 front portion; This blade 2 also is arranged on cutter hub 1 front end both sides, and what it adopted is the carbide chip that Hardmetal materials is made, and adopts the soldering welding fixing between this carbide chip and the cutter hub 1, increases steadiness.
By digital controlling plasma powder spray welding apparatus, the wearable overlay 3 that one deck has cemented carbide powder to make is set on cutter hub 1, these wearable overlay 3 thickness are 3～5mm, avoid the wearing and tearing of cutter hub 1, itself and cutter hub 1 bond strength height.
What cutter hub 1 material of present embodiment adopted is Aldecor, it is anterior near near the position the carbide chip that its wearable overlay 3 is wrapped in cutter hub 1, cover on the surface of cutter hub 1, further increase the rub proofness of cutter hub 1, prevented the sand of any direction, stones etc. prolong the physical life of blade to the wearing and tearing of cutter hub 1.
In the present embodiment, the built-up welding position of wearable overlay 3 is in position, end in face of carbide chip and cutter hub 1 cutwork, and built-up welding thickness is 3-5mm, has protected cutter effectively in cutwork, has prolonged application life of cutter.
Based on above-mentioned, the present invention is by being provided with the wearable overlay 3 of one deck spray coating of alloy powder on cutter hub 1, cutter hub 1 adopts Aldecor, and blade 2 adopts carbide alloy, and weld by soldering, its Stability Analysis of Structures, the rub proofness height, simultaneously, in the work progress, reduce the replacing of blade, reduced construction cost, accelerated construction speed; It has simple in structure, easy to use, and stability is high, and the advantage of beautiful appearance is worthy of popularization.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof
