Radial Forging M2-High Speed Steel On Different Hammer And Feed Influence On Carbide

High-speed steel is a kind of critical and basic consumptive material in machinemanufacturing, and it is also an important material to be used to produce a variety ofmachine cutting tools, high load mold, aerospace, high temperature bearings and specialheat-resistant and wear-resistant parts. The tools and basic materials made by high-speedsteel should have a higher strength, hardness and toughness, and on the performance of thehigh speed steel paper put forward higher request, and the factors that influence theseperformance have direct relationships with the particle size and uniformity of thehigh-speed steel carbide. The particle size and uniformity of the high-speed steel play acrucial role in forming the quality and performance of the high-speed steel.M2high speed steel is a commonly used high speed steel that belongs to Tungstenand molybdenum system high speed steel. M2high speed steel is the source material ofmain machine cutting tools and widely used in machinery manufacturing. The thick anduneven ledeburite exit in the cast carbide structure so that the t strength、hardness andtoughness is not high. The article takes the M2high speed steel as an example, and mainlyresearches the effect of different forms of the hammerhead and process parameters oncarbide when the radial forging of M2high speed steel is cogging, and analyses the prosand cons of different hammer on cogging process of radial forging M2high speed steel intheory, and discusses the mechanism of the defects generated by the radial forging M2high speed steel, and illustrates the effect of different hammerhead types and different feedof GFM forging machine to forging permeability of high-speed steel and the particle sizeand uneven of carbide.Using the Deform-3D finite element simulation software to simulate the deformationprocess of radial forging of M2high speed steel with different hammers, different feedrates and other conditions, and get the cloud map state of deformation strain field and therelated map information, and reveal intuitively the impact of different hammer structuretypes (universal hammer and flat hammer), different feed rates (according to equipmentlimited feeding1.5m/min~3.0m/min) to the particle size and the uneven of radialforging of M2high speed steel carbide. The study found that carbide distributedhomogeneously with the universal hammer in the amount of2.5m/min into radial forgingof M2high speed steel.The experiment on radial forging M2high speed steel shows that with the universal hammer in the speed of2.0m/min and the flat hammer in speed of2.0m/min radial forgingM2high speed steel respectively, carbide detection experiment indicate that with theuniversal hammer in the feed rate of2.5m/min in radial forging of M2high speed steel,the distribution of carbides are homogeneous and the forging permeability is good. Withthe universal hammer in the feed rate of2.0m/min and flat hammer in the feed rate of2.0m/min and2.5m/min in radial forging of M2high speed steel, forging microstructurehave the carbide network, angular grain carbide, and the carbide is not completely broken,and forging permeability is not ideal. The experimental and simulative results areconsistent.Comprehensive analysis shows that the more reasonable radial forging process of M2High Speed Steel is using universal hammer in2.5m/min when feeding the radial forgingM2high speed steel will generate a uniform dispersion of carbon dioxide organization,and improve the performance of high speed steel paper..
