What is the manufacturing process of bucket teeth?

1) heating: the ingot iron that buying is come is put into feeding mouth and is sent to intermediate-frequency heating furnace and heat-treats, and wherein ingot iron is 1200 DEG C through intermediate-frequency heating furnace heating-up temperature;

2) forge embryo: the ingot iron after heating is is tentatively forged and pressed by forging embryo machine;

3) forging forming: the thick embryo of tentatively forging and stamping is passed through to forging press forging forming;

4) edge-cutting and hole-punching: the germule of forging forming is carried out to trimming and punching;

5) mark: the bucket tooth after edge-cutting and hole-punching is carried out to words identification;

6) insulation normalizing: the product insulation of having forged is processed;

7) heat treatment: heating quenching, lonneal, wherein hardening heat is 880 DEG C, temperature is 250 DEG C;

8) ramming: the bucket tooth after quenching is entered to ramming, remove surface oxidation, polishing;

9) flaw detection: product surface is carried out to magnetic powder inspection, inspection product surface crack defect.

Embodiment 3:

A kind of excavator bucket teeth manufacture craft, comprises the following steps:

1) heating: the ingot iron that buying is come is put into feeding mouth and is sent to intermediate-frequency heating furnace and heat-treats, and wherein ingot iron is 1220 DEG C through intermediate-frequency heating furnace heating-up temperature;

2) forge embryo: the ingot iron after heating is is tentatively forged and pressed by forging embryo machine;

3) forging forming: the thick embryo of tentatively forging and stamping is passed through to forging press forging forming;

4) edge-cutting and hole-punching: the germule of forging forming is carried out to trimming and punching;

5) mark: the bucket tooth after edge-cutting and hole-punching is carried out to words identification;

6) insulation normalizing: the product insulation of having forged is processed;

7) heat treatment: heating quenching, lonneal, wherein 900 DEG C of quenchings, 270 DEG C of lonneals;

8) ramming: the bucket tooth after quenching is entered to ramming, remove surface oxidation, polishing;

9) flaw detection: product surface is carried out to magnetic powder inspection, inspection product surface crack defect.

Beneficial effect of the present invention is: forged and pressed and increased the hardness of bucket tooth and wearability by secondary, through entering oil and quenching after reason, performance is obviously better than the properties of product that additive method is produced, and hardness, the impact toughness of bucket tooth improve greatly, and has obtained more martensitic structure.Relatively common investment-casting, wearability has improved more than 3 times.

Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendments or supplement or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.

Bucket teeth are a necessary part of excavator equipment, similar to human teeth, but also vulnerable parts, is composed of a combination of bucket teeth and tooth tip, the two are connected by the pin shaft, how its application effect, for the application of the whole excavator, will have a great impact. In terms of the product itself, different processes are made of certain differences in all aspects.

Sand casting process manufacturing: some bucket teeth in the manufacturing, the use of sand casting process. The cost of products made by this kind of process is relatively low, so the quality and function of the whole product are relatively not very high.

Forging and casting process manufacturing: the cost of the bucket teeth made of forging and casting process is higher than the products of sand casting process. Relatively speaking, the products made of this process will have more advantages in quality.

Precision casting process manufacturing: relatively speaking, the bucket teeth manufactured by this process are relatively moderate in all aspects, that is to say, the manufacturing cost is relatively moderate, and the quality of the products is also in the middle. But in terms of the application of this kind of process, there are very strict requirements for the raw materials used in the product.
