Abstract
The utility model discloses a steam turbine wavy cutting edge form milling cutter which comprises a cutter body, wherein the cutter body is provided with a cutting edge, and the outer surface of the cutting edge is provided with a waveform chip-breaking trough. The milling cutter of the utility model has the advantages of high processing efficiency, good durability, long service life and the like. The utility model is a novel highly effective semi-finishing formed cutter for the processing of modern steam turbine troughs.
Description
Technical field
The utility model relates to a kind of ripple sword profile milling cutter that is used to process turbo rotor groove.
Background technology
Steam turbine wheel slot wave sword profile milling cutter is commonly called as ripple sword Christmas tree milling cutter.The processing of tradition turbo rotor groove adopts roughing milling cutter-V-type roughing milling cutter (equal helix angle taper mill or waveform sword race roughing milling cutter), common Christmas tree moulding half finish-milling cutter, three kinds of milling cutters of common Christmas tree moulding finish-milling cutter to finish, main processing capacity is on roughing milling cutter and common Christmas tree moulding half finish-milling cutter, and common Christmas tree profile milling cutter cutting edge is a tree-like curve on smooth Christmas.Because the turbo rotor groove working depth is darker, the Tool in Cutting amount is big, and cutting resistance is big, and tool wear is fast, and the turbine rotor material is heat-resistance stainless steel, the intensity height, and cutting ability is poor, cut several times, and working (machining) efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of working (machining) efficiency height, durability steam turbine good, long service life is taken turns slot wave sword profile milling cutter.
For solving the problems of the technologies described above, the utility model steam turbine wheel slot wave sword profile milling cutter comprises cutter hub, and described cutter hub is provided with cutting edge, and the outer surface of described cutting edge is provided with the waveform chip-breaker.
Above-mentioned steam turbine wheel slot wave sword profile milling cutter, set chip-breaker is shaped as sine wave on the described cutting edge outer surface.
Above-mentioned steam turbine wheel slot wave sword profile milling cutter, described cutter hub is made by powder high-speed tool steel or high cobalt high-speed tool steel.
The utility model is owing to adopted above-mentioned technical pattern, it changes the smooth curve moulding cutting edge of former common Christmas tree profile milling cutter into the moulding cutting edge of sinusoidal waveform chip-breaker, utilize and divide the bits principle to make smear metal become grain of rice shape by former linear, chip removal is easy, cutting resistance is significantly reduced, stock-removing efficiency increases substantially, and improves 3～5 times of machining efficient than common Christmas tree profile milling cutter.The utility model milling cutter vibration damping is good, cutting fluid is easy to enter cutting zone along waveform sword crest and trough surface, helps the cooling and lubricating of cutter tooth, and cutting is participated in the blade dislocation of waveform blade milling cutter by turns, thereby alleviate the wearing and tearing of cutter, help improving the durability of cutter.Need to adopt three kinds of milling cutters to finish than traditional turbo rotor groove processing, adopt the utility model wheel slot wave sword profile milling cutter only to need and common Christmas tree moulding finish-milling cutter together, just can finish turbo rotor groove processing, be about to rough mill with half finish-milling and unite two into one, place of crude milling cutter-V-type roughing milling cutter and two kinds of milling cutters of common Christmas tree moulding half finish-milling cutter, the work that original cutting two cuttves are finished, cut a cutter and can easily finish processing, improved production efficiency greatly, thereby also made the utility model milling cutter become the new and effective half precisive shaped cutter of modern steam turbine race processing usefulness.Cutter can adopt powder high-speed tool steel or high cobalt high-speed tool steel on material, its hardness can reach HRC66～68, and red hardness and toughness are fabulous, and its durability is tens times of common high-speed tool steel cutter, the service life of having improved cutter so greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model steam turbine wheel slot wave sword profile milling cutter;
Fig. 2 is the structure for amplifying schematic diagram of cutting edge part among Fig. 1.
The specific embodiment
As shown in Figure 1, steam turbine wheel slot wave sword profile milling cutter comprises cutter hub 1, cutter hub 1 to be shaped as Christmas tree-like, make by powder high-speed tool steel or high cobalt high-speed tool steel.Cutter hub 1 is provided with cutting edge 2.As shown in Figure 2, the outer surface of cutting edge 2 is provided with sinusoidal waveform chip-breaker 3.
In the utility model structure, the shape of set chip-breaker 3 is not subjected to sinusoidal wave the limit on cutting edge 2 outer surfaces, can be other waveform yet.
Claims (3)
1. steam turbine wheel slot wave sword profile milling cutter comprises cutter hub, and described cutter hub is provided with cutting edge, it is characterized in that, the outer surface of described cutting edge is provided with the waveform chip-breaker.
2. steam turbine as claimed in claim 1 wheel slot wave sword profile milling cutter is characterized in that, set chip-breaker is shaped as sine wave on the described cutting edge outer surface.
