The V shaped conical hammer anvil used of rotary swaging machine radially
Technical field
The present invention relates to a kind of Forging Technology, particularly relate to a kind of radially rotary swaging machine and forge the V shaped conical hammer anvil that long-axis forging uses, can improve the horizontal mechanical performance of forging.
Background technology
Radially rotary swaging machine has orthogonal four hammer anvils, makes the radially pressurized die cavity internal strain of blank an approximate sealing to hitting in twos, has good process plastic, is particularly suitable for the finish forge of axle, rods and bars class change section elongate articles.Radially rotary swaging machine uses common hammer anvil to forge; Workpiece extends soon vertically; Production efficiency is high; But the horizontal mechanical performance of forging is poor than axial property, and the ratio of the ratio of the transverse strength limit and the axial strength limit, transverse impact toughness and axial impact toughness is general all less than 0.8, is difficult to reach requirement for the demanding forging of lateral performance.
Summary of the invention:
For improving the radially horizontal mechanical performance of rotary swaging machine forging, the V shaped conical hammer anvil that the present invention provides a kind of radially rotary swaging machine to use.Use V shaped conical hammer anvil to substitute common hammer anvil and forge, can improve the horizontal mechanical performance of forged shaft, make its ratio reach 0.95~1.0 with axial mechanical performance.
The technical scheme that the present invention adopted is: in the high temperature resistant zone of the hammer anvil sizing area and arranged on left and right sides master working face that rotary swaging machine radially uses, and the infall of utonomous working face and transition plane
The tapered projection of two parts that built-up welding goes out to be mutually symmetrical in the zone that limits, said tapered projection is V-shape on vertical view, and its angle is α, α=60 °~120 °, tapered projection and main working face inclination angle are β, β=8 °~20 °; The tapered width of tapered projection is C
1=50~100mm, tapered height are C
2=5~20mm, vertex of a cone rounding RC
3=10~30mm.Through setting up V shaped conical projection, can effectively improve the horizontal mechanical performance of forged shaft; Change V-type angle α, angle of inclination beta and the tapered width and height of V shaped conical jut, can adjust the ratio of horizontal mechanical performance of forging and axial mechanical performance.
Adopt V shaped conical hammer anvil to compare with using common hammer anvil; The present invention has following beneficial effect: the radially horizontal mechanical performance of rotary swaging machine forging is improved in (1), makes the ratio of ratio, transverse impact toughness and the axial impact toughness of the transverse strength limit and the axial strength limit reach 0.95-1.0.(2) change V-type angle α, angle of inclination beta and the tapered width and height of V shaped conical jut, can adjust the horizontal mechanical performance of forging and the axial ratio of mechanical performance.
