Abstract
The utility model relates to a multipurpose steam turbine die without shrouded blade, comprising a forging die, a drilling jig and a drilling jig fixing plate, wherein the upper surface of the forging die is provided with an inverse trapezoidal groove; two end faces of the forging die are connected with the drilling jig fixing plate through screws, and the center of the drilling jig fixing plate is provided with an inverse trapezoidal inner cavity superposed with the inverse trapezoidal groove; an inverse trapezoidal drilling jig is connected and embedded in the inverse trapezoidal inner cavity; the drilling jig has an inverse trapezium structure just embedded with the inverse trapezoidal inner cavity, the inner side end face of the drilling jig extends into the inverse trapezoidal groove of the forging die and is embedded with the inverse trapezoidal groove; and the drilling jig is provided with three drilling holes positioned in a same horizontal line. During processing of blades, the multipurpose steam turbine die without the shrouded die can forge trapezoidal blanks more approximate to the molding surface of a shrouded blade than the original cuboid blank through the forging die, is material-saving, and reduces machining allowance, performs milling and clamping of two end faces by directly using the forging die, and can make rapid and accurate positioning through the drilling holes in the drilling jig by mounting the drilling jig fixing plate and the drilling jig when carrying out drilling of center holes.
Description
Technical field
The utility model relates to a kind of mould, and particularly a kind of multipurpose steam turbine is not with hat stator blade mould.
Background technology
Traditional steam turbine is not with in the hat stator blade production process, and at first forging rectangle blank mills, four sides and two end faces of sanding base, bores the two ends center hole, mills the inner arc surplus in advance, mills back of the body arc surplus in advance, mills interior, convex profile by the 4-coordinate numerical control at last.It exists shortcoming to be: blank is a rectangle, will be processed into the arc stator blade at last, and milling amount is big, and working (machining) efficiency is low, takes material; Boring center hole needs can hole behind workman's mark, very inconvenient.
The utility model content
The technical problems to be solved in the utility model provides a kind of multipurpose steam turbine and is not with hat stator blade mould, can be used for carrying out blank forging, clamp, can conveniently carry out the boring of center hole again.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of multipurpose steam turbine is not with hat stator blade mould, comprise forging die, drill jig and drill jig fixed head, its innovative point is: described forging die upper surface is provided with the dovetail groove that falls of the left and right end face of a perforation; The both ends of the surface of described forging die are connected with the drill jig fixed head by screw, the center of this drill jig fixed head has and falls the trapezoidal inner chamber that falls that dovetail groove overlaps, falling to connect the chimeric trapezoidal drill jig that has down in the trapezoidal inner chamber, described drill jig for can be just with fall the chimeric inverted trapezoidal structure of trapezoidal inner chamber, its inner side end stretches in the dovetail groove of forging die, and with this to fall dovetail groove chimeric, be provided with three borings that are positioned on the same horizontal line on the described drill jig.
Advantage of the present utility model is: when carrying out blade processing, can forge than original cuboid blank more near the trapezoidal blank of stator blade profile by forging die, save material, reduce allowance; Vane machine adds the milling that directly utilizes forging die to carry out both ends of the surface man-hour and clamps; And need bore center hole the time, install drill jig fixed head and drill jig, carry out spitting drill center hole fast and accurately by the boring on the drill jig.
Description of drawings
Fig. 1 is not with hat stator blade mould structure schematic diagram for the utility model multipurpose steam turbine.
Fig. 2 is along A-A line cutaway view among Fig. 1.
Fig. 3 is that the utility model multipurpose steam turbine is not with drill jig fixed head and the chimeric schematic diagram of drill jig of being preced with the stator blade mould.
The specific embodiment
As shown in Figure 1, 2, 3, comprise forging die 1, screw 5, drill jig fixed head 2, drill jig 3, boring 4.
Above-mentioned forging die 1 upper surface is provided with a dovetail groove that falls that connects left and right end face, is connected with drill jig fixed head 2 in the both ends of the surface of forging die 1 by screw 5, and the center of this drill jig fixed head 2 has the trapezoidal inner chamber that falls that overlaps with dovetail groove.Drill jig 3 for can be just with fall trapezoidal inner chamber, the chimeric inverted trapezoidal structure of dovetail groove that falls, its thickness is greater than the thickness of drill jig fixed head 2, the outside end face of drill jig 3 is connected chimeric with falling of drill jig fixed head 2 trapezoidal inner chamber, inner side end stretches in the dovetail groove of forging die 1, and with this to fall dovetail groove chimeric, be provided with three borings 4 that are positioned on the same horizontal line on the drill jig 3.
Claims (1)
1. a multipurpose steam turbine is not with hat stator blade mould, comprises forging die, drill jig and drill jig fixed head, it is characterized in that: described forging die upper surface is provided with the dovetail groove that falls of the left and right end face of a perforation; The both ends of the surface of described forging die are connected with the drill jig fixed head by screw, the center of this drill jig fixed head has and falls the trapezoidal inner chamber that falls that dovetail groove overlaps, falling to connect the chimeric trapezoidal drill jig that has down in the trapezoidal inner chamber, described drill jig for can be just with fall the chimeric inverted trapezoidal structure of trapezoidal inner chamber, its inner side end stretches in the dovetail groove of forging die, and with this to fall dovetail groove chimeric, be provided with three borings that are positioned on the same horizontal line on the described drill jig.
