The performance of the excavator also
depends on the bucket. The bucket is one of the main components of the working
device of the excavator. During the excavation operation, the working conditions
of the bucket teeth are very bad because of the ore, rock or soil. . .In the
excavation operation, the bucket teeth must not only be subject to sliding wear
but also bear a certain impact load, which greatly shortens the service life of
the bucket teeth. The damage of bucket teeth will not only cause material waste
and economic loss, but also directly affect the production schedule. So why is
there a serious problem of tooth wear? How to solve it? How to increase the
service life of excavator bucket teeth?
In order to improve the wear resistance of
the tooth surface, it is very necessary to choose a reasonable welding material
during surfacing. The selection principle of high-manganese steel substrate
surface surfacing welding material is that, as long as it can withstand the
material impact and can withstand a large impact load during use, choose a pile
with high hardness and good wear resistance as much as possible. Welding alloy
materials.
For example, the austenitic manganese steel
surfacing alloy material should be used for the surfacing of the bucket teeth
used in the working place where the collision is very strong.
During the working process of the
excavator, the teeth on both sides generally wear about 30% faster than the
teeth in the middle of the bucket. When the teeth on both sides are much
shorter than the teeth in the middle, the teeth on both sides and the middle
can be used. Continue to use the interchanged position, which can reduce the
number of repairs and indirectly increase the service life of the teeth. Before
the wear of the bucket teeth reaches the limit of use, surfacing welding should
be repaired in time.
