Abstract
A tunnel boring machine cutter comprises a base body, a groove formed in a cutting edge part of the base body and a blade arranged in the groove, and is characterized in that an abrasion resistant layer is arranged on the periphery of the groove, and a plurality of abrasion resistant blocks are arranged at the top of the base body. The tunnel boring machine cutter has the advantages of corrosion resistance, easiness in cleaning, solidness, low probability of deformation as well as durability due to the fact that the abrasion resistant layer and the abrasion resistant blocks are made of high-strength cemented carbide in a build-up welding manner.
Description
Technical field
The present invention relates to shield machine technical field, be specifically related to a kind of shield machine cutter and preparation method thereof.
Background technology
Shielding tunnel excavator, is called for short shield machine.A kind of special engineering machinery of tunnel piercing, that modern shield excavation machine integrates is light, mechanical, electrical, liquid, sensing, information technology, there is the excavation cutting soil body, conveying soil quarrel, assembled tunnel lining, measure the functions such as guiding correction, relate to the 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 the construction of tunnel such as subway, railway, highway, municipal administration, water power.Shield machine cutter is as the vital building block of shield machine, the quality of its performance directly has influence on the progress of engineering, during due to excavation, often run into the objects such as scleroid stone, metal, this just has higher requirement to the hardness of shield machine cutter, abrasion resistance, and existing shield machine cutter is conveniently also short of to some extent at this.
Summary of the invention
For the existing problem of the above-mentioned tool of production, it does not reach perfection inventor's thoughts, then exhausting the concentrated research of its intelligence overcomes, with it, be engaged in this industry working experience for many years, develop a kind of shield machine cutter and preparation side thereof, there is anticorrosion, easy to clean, firm, not yielding, long-lived advantage.
For achieving the above object, the technical scheme that the present invention takes is:
, comprise matrix, be located at matrix cutting edge portion groove, be located at the blade in groove, it is characterized in that, groove periphery arranges wearing layer, matrix top arranges some wear-resistant blocks.
As preferably, described wearing layer is that high-abrasive material built-up welding forms.
As preferably, described blade is carbide alloy, and the mode by welding is embedded in groove, and weld is placed silk screen.
As preferably, described wear-resistant block is the cylinder of Y98 Hardmetal materials.
Another object of the present invention is the preparation method who proposes a kind of shield machine cutter, makes it easy to manufacture.
This purpose of the present invention realizes by following technological process:
(1), machine: adopt machine that raw material are made into cutter workpiece;
(2), built-up welding: built-up welding processing is carried out in workpiece blade oral area groove periphery;
(3), heat treatment: workpiece is heat-treated and improved its performance;
(4), surfacing: surface of the work is polished, make it Paint Gloss;
(5), correct: workpiece is corrected, made it more accurate;
(6), antirust processing: workpiece is done to antirust processing, prevent that it from getting rusty.
As preferably, the above-mentioned disposable build-up wear-resistant layer of JY49-1 material that adopts in step (2).
As preferably, the thickness of described disposable built-up welding is 4-6mm.
As preferably, described heat treatment is modifier treatment, and temperature is 550-600 ℃.
As preferably, described be antirustly treated to vacuum coating and process.
A kind of shield machine cutter of the present invention and preparation method thereof, has made up the deficiencies in the prior art, has anticorrosion, easy to clean, firm, not yielding, long-lived advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and example, the present invention will be further described.
As shown in the figure, a kind of shield machine cutter, comprise matrix 1, be located at matrix 1 cutting edge portion groove 5, be located at the blade 4 in groove 5, it is characterized in that, groove 5 peripheries arrange wearing layer 3, matrix 1 top arranges some wear-resistant blocks 2, described wearing layer 3 forms for high-abrasive material built-up welding, and described blade 4 is carbide alloy, and the mode by welding is embedded in groove 5, weld is placed silk screen 6, and described wear-resistant block 2 is the cylinder of Y98 Hardmetal materials.
The manufacturing process flow of above-mentioned shield machine cutter is:
(1), machine: adopt machine that raw material are made into cutter workpiece;
(2), built-up welding: built-up welding processing is carried out in workpiece blade oral area groove periphery;
(3), heat treatment: workpiece is heat-treated and improved its performance;
(4), surfacing: surface of the work is polished, make it Paint Gloss;
(5), correct: workpiece is corrected, made it more accurate;
(6), antirust processing: workpiece is done to antirust processing, prevent that it from getting rusty.
The peripheral JY49-1 of employing of the cutting edge portion groove material of the cutter workpiece that machine in step (1) is obtained carries out disposable build-up wear-resistant layer to be processed, built-up welding thickness is 4-6mm, again the workpiece of heap postwelding is carried out to modifier treatment, improve its intensity, plasticity and toughness, the temperature of modifier treatment is 550-600 ℃, afterwards cutter is polished and corrects, make it more attractive in appearance, accurate, finally carry out antirust processing, the present invention adopts the antirust treatment technology of advanced vacuum coating, favorable rust preventing effect.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, any modification of doing within all spirit in invention and principle, be equal to and replace and improvement etc., within being all included in protection scope of the present invention.
