Abstract
The utility model relates to a special mechanically clamped digital control cutter for processing turbine rotor blade grooves. The utility model is characterized in that spiral chip discharging grooves (3) are uniformly arranged on a tapered cutter body (2) along the axial direction, blade grooves (4) are uniformly arranged along the circumference at equal intervals, blades (5) are fixed on steps formed by the spiral chip discharging grooves (3) and the blade grooves (4) through clamp screws (6), and the cutting edge shape of the blades (5) fits with the circumferential shape of the steps. The cutter adopting spiral chip discharging grooves and exchangeable blades has the characteristics of good chip discharging effect, low cost and resource saving.
Description
Technical field:
The utility model relates to a kind of cutter of processing vapor turbine wheel blade, a kind of specifically special machine folder NC cutting tool of processing vapor turbine wheel blade groove.
Background technology:
Steam turbine is one of visual plant in the electricity generation system, the turbine rotor blade is the critical piece on the steam turbine equipment, grooved to root of blade adds man-hour, uses monoblock type carbide alloy or high-speed steel tool usually, and processes axial chip area and leave cutting edge by grinding machine.This cutter chip removal performance is undesirable, and can not reface because profile geometries changes after the sword rust, only destroys the cutter that more renews, so the cost height, the waste resource.
The utility model content:
For solve described in the background technology because of more renewing cutter, and produce cost height, waste problem of resource, the utility model provides a kind of special machine folder NC cutting tool of processing vapor turbine wheel blade groove.This cutter adopts spirality chip area and changeable type blade, has that chip removal is effective, cost is low, the characteristics that economize on resources.
The technical solution of the utility model is: a kind of special machine folder NC cutting tool of processing vapor turbine wheel blade groove, comprise handle of a knife and be fixed in the cutter hub that is taper type of handle of a knife front end, axial distributing auger shape chip area on the cutter hub of taper type wherein, circumferentially equidistantly be furnished with insert groove, and pass through the pinching screw fixed blade on spirality chip area and formed each step of insert groove, and the profile of the blade shape of blade and step periphery coincide.
Described spirality chip area is 3, and insert groove is 4.
The beneficial effects of the utility model are: because the spirality chip area is set on cutter hub, is easy to iron filings and discharges, make processing characteristics and efficient improve; Blade is selected the changeable type blade in addition, and cutter hub can be reused, and so just reduces the use cost of cutter greatly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model:
Fig. 2 is that the A of Fig. 1 is to view.
1-handle of a knife among the figure, 2-cutter hub, 3-chip area, 4-insert groove, 5-blade, 6-pinching screw.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, the special machine folder NC cutting tool of this processing vapor turbine wheel blade groove, comprise handle of a knife 1 and be fixed in the cutter hub that is taper type 2 of handle of a knife 1 front end, axial uniform 3 spirality chip areas 3 on the cutter hub 2 of taper type wherein, circumferentially equidistantly be furnished with 4 insert grooves 4, as shown in Figure 2, and on spirality chip area 3 and insert groove 4 formed each step, pass through pinching screw 6 fixed blades 5, and the profile of the blade shape of blade 5 and step periphery coincide.
Claims (2)
1. the special machine of a processing vapor turbine wheel blade groove presss from both sides NC cutting tool, comprise handle of a knife (1) and be fixed in the cutter hub that is taper type (2) of handle of a knife (1) front end, it is characterized in that: the cutter hub (2) at taper type is gone up axial distributing auger shape chip area (3), circumferentially equidistantly be furnished with insert groove (4), and pass through pinching screw (6) fixed blade (5) on spirality chip area (3) and formed each step of insert groove (4), and the profile of the blade shape of blade (5) and step periphery coincide.
2. according to the special machine folder NC cutting tool of the processing vapor turbine wheel blade groove under the claim 1, it is characterized in that: spirality chip area (3) is 3, and insert groove (4) is 4.
