Influence of the material of wood crusher blade

Analysis of the influence of the material of wood crusher blade on the machine

The blade is the teeth of the wood crusher, the material of the blade is good or bad directly determines the height of the mill.According to the classification of cemented carbide, and in the use of different occasions, even if the damage is maintained at a minimum,they also only in toughness, wear and crater wear knife, and comparison between plastic deformation sensitivity.This limitation means that the wood crusher blade only in the alloy composition and microstructure at the same time, a variety of materials can be compared.The processing of wood crusher with intermittent cutting or cutting depth.For example, milling or copying turning often due to fatigue crack damage caused by wood crushing equipment blade.Through the establishment of special test conditions to reduce the impact of wear and toughness loss, it is possible to compare the usefulness of different cemented carbide materials to fatigue cracks.
There are two types of fatigue cracks on the blade of wood crusher, that is, the crack perpendicular to the cutting edge and the crack parallel to the cutting edge.These two types of cracks can be produced on the surface of the alloy, or on the back surface of the alloy blade base.The first kind of crack is mainly caused by the thermal fatigue effect, and its formation is earlier than the change of cutting force.At this time, the need to add coolant in the grinding, in order to reduce the heat generated when cutting blade, the alloy blade to produce adverse effects.
