Abstract
The invention provides a manufacturing process for excavator bucket teeth. The manufacturing process comprises the first step of heating iron ingots, the second step of forging billets, the third step of forging, pressing and forming the billets, the fourth step of trimming and punching the billets, the fifth step of performing identification on the bucket teeth, the sixth step of performing normalization, the seventh step of performing heat treatment, the eighth step of performing sand polishing and the ninth step of performing flaw detection. The manufacturing process for the excavator bucket teeth has the advantages that the hardness and abrasion resistance of the bucket teeth are enhanced through secondary forging and pressing; the performance of the bucket teeth is remarkably superior to the performance of bucket teeth produced through other methods after the bucket teeth are put into oil and quenched; the hardness and impact toughness of the bucket teeth are greatly enhanced, and more martensitic structures are obtained. Compared with a common investment casting, the abrasion resistance of the bucket teeth is enhanced by more than three times.
Description
Technical field
The present invention relates to a kind of accessory of excavator, belong to excavator technical field, be specifically related to a kind of excavator bucket teeth manufacture craft.
Background technology
Excavator bucket teeth is the vitals on excavator, be similar to people's tooth, also be consumable accessory, at present, bucket tooth on market is that foundry goods wearability and hardness are lower, and fragile in the process using, replacement frequency is higher, increase greatly the cost that excavator uses, wasted more natural resources.
Summary of the invention
For above problems of the prior art, a kind of bucket tooth that the present invention uses the heat treatment gas of a kind of special, wear-resistant material use FMT combination to make
The present invention is achieved by the following technical solutions:
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;
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;
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.
Further, described step 1) in ingot iron be 1180-1220 degree Celsius through intermediate-frequency heating furnace heating-up temperature.
Further, 7) in, add 86 DEG C of quenchings of bucket tooth tempering hot temperature degree, 250 ± 20 DEG C of lonneals.
Detailed description of the invention
Embodiment 1:
