Abstract
The invention discloses a machining technology of a wind-power blade die for replacing five shafts by three shafts. On a three-shaft numerical control machining center, a mold core molded surface is machined by utilizing different cutters. Firstly, a ball milling cutter with the diameter of 80mm is adopted, a program which is programmed in advance is used for machining most surfaces, then, an end mill with the diameter of 20mm and the bottom fillet diameter of 2mm is used for back chipping, and positions which can not be machined by the cutter with the diameter of 80mm are machined; and finally, a ball milling cutter with the diameter of 4mm is used for back chipping, and positions which can not be machined by the cutter with the diameter of 20mm are machined. According to the machining technology, the effect same with the effect obtained by utilizing a five-shaft machining center machines to machine a wind-power blade mold core can be achieved. The machining cost of the wind-power blade mold core can be greatly lowered.
Description
Technical field
The present invention relates to the wind-powered electricity generation industry, is the technology that wind-powered blade mold is replaced five-shaft numerical control processing with three-axis numerical control processing specifically.
Background technology
At present, the wind-powered electricity generation industry belongs to the new forms of energy industry, has sustainable use and does not have pollution characteristics.Each state is all in the development and utilization of advocating energetically new forms of energy, and China has also accelerated the industrialization of wind-powered electricity generation industry, and the blade of one of wind-powered electricity generation industry important components is the processing and manufacturing of pattern tool.Existing blade mfg. moulding die has the advantages that volume is big, precision is high, profile is complicated, and by five machining center manufacturings, it is long to have produced the production cycle thus, and available devices is few, the problem of processing charges costliness.
Summary of the invention
The problem that this technology will solve is the range of application that enlarges three-axis numerical control processing, and it is applied to the processing of wind electricity blade core rod, to improve the range of application of three-axis numerical control machining center, reduces the production cost of wind electricity blade core rod.
The technical solution adopted for the present invention to solve the technical problems is:
On the three-axis numerical control machining center, adopt different cutter processing core rod profiles.Because the profile of wind electricity blade core rod is the space three-dimensional curved surface, therefore adopt flat cutter formula vertical milling cutter to be difficult to realize processing request.This processing technology is at first to adopt the rose cutter of 80 millimeters of diameters, on lathe, process most surface with the program of finishing in advance, adopt the slotting cutter elder generation back chipping of 2 millimeters of radiuss of corner at the bottom of 20 millimeters of the diameters then, 80 millimeters cutters process less than the position process.At last, the rose cutter that adopts 4 millimeters of diameters is back chipping again, 20 millimeters cutters processing of diameter less than the position process.Adopt such processing technology, just can reach five identical processing effects of Cutter Body Processing with Machining Center wind electricity blade core rod fully.
The invention has the beneficial effects as follows that present technique adopts different cutter and processing method, the feasible wind electricity blade core rod that originally must process on five machining centers is realized on three machining centers.Can greatly reduce the processing cost of wind-powered electricity generation core rod, also greatly expand the range of application of three machining centers.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is that the wind electricity blade core rod is the processing process figure of three-dimension curved surface.
Fig. 2 is that the wind electricity blade core rod is the cutter structure figure of three-dimension curved surface.
The rose cutter of 80 millimeters of 1. diameters among Fig. 2, the 2. slotting cutter of 2 millimeters of radiuss of corner at the bottom of 20 millimeters of the diameters, the 3. rose cutter of 4 millimeters of diameters.
The specific embodiment
Be the model surface of space three-dimensional curved surface for curved surface in Fig. 1, processing sequence is a step 1, two, three as shown in Figure 1.At first use the rose cutter (1) of 80 millimeters of diameters, on lathe, process most surface with the program of finishing in advance, use the first back chipping of slotting cutter (2) of 2 millimeters of radiuss of corner at the bottom of 20 millimeters of the diameters then, the processing of the rose cutter (1) of 80 millimeters of diameters less than the position process.At last, with the rose cutter (3) of 4 millimeters of diameters back chipping again, slotting cutter (2) processing of 2 millimeters of radiuss of corner at the bottom of 20 millimeters of the diameters less than the position process.Through above processing technology, just can finish curved surface is the wind electricity blade core rod of space three-dimensional curved surface.
Claims (1)
1. three of wind-powered blade molds replace five axis processing techniques, it is characterized in that: on three machining centers, be that the model of space three-dimensional curved surface adopts different cutter processing core rod profiles for curved surface, rose cutter with 80 millimeters of diameters processes most surface earlier, use the slotting cutter elder generation back chipping of 2 millimeters of radiuss of corner at the bottom of 20 millimeters of the diameters then, at last, with the rose cutter of 4 millimeters of diameters back chipping again.
