Background technology
Along with the requirement of people to the comfortableness of car is more and more higher, also more and more higher to the power requirement of generator, people require also more and more to pay attention to, so the weight of automobile main frame maker to each parts is more and more harsher to the oil consumption of car at present simultaneously.Based on the light-weighted requirement of generator high power, at present a lot of generator plant begins one's study hybrid excitation generator, the difference of hybrid excitation generator and common generator is mosaic magnet between the pawl pole, front and back of generator amature, considerably increase the magnetic property of pawl pole, thus add power output and the efficiency of generator greatly.
Existing hybrid excitation generator rotor inlays permanent magnet equably between pawl pole, front and back.In the magnet groove that the magnet locating surface that permanent magnet is embedded in pawl pole, front and back is formed, the lateral surface of permanent magnet is close on magnet support face, guarantees that generator permanent magnet when High Rotation Speed can not throw away.And due to permanent magnet surrounding fillet due to the reason of processing technology can not do larger, therefore the fillet of the pawl magnet support face of extremely going up and magnet locating surface intersection just requires very little, generally can not more than R0.5mm, but current pawl pole Forging Technology can not meet the technological requirement of the fillet of magnet support face and magnet locating surface intersection.
The processing technology of existing hybrid excitation generator pawl pole is Milling Machining magnet groove after rough forging, and production efficiency is low.
Summary of the invention
The object of the invention is the defect overcoming prior art existence, provide a kind of hybrid excitation generator pawl very hot forging cold-extruded manufacturing process that the magnet support face of pawl pole and the radius of corner of magnet locating surface intersection are not more than 0.5mm that can ensure, and production efficiency is high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hybrid excitation generator pawl very hot forging cold-extruded manufacturing process, comprise the following steps: blanking → heating → forging → trimming → ball blast → cold-extruded → brill endoporus → right boring endoporus → car yoke end face, wherein:
During forging, a capaciting material groove is set at magnet locating surface and intersection, magnet support face;
Cold-extruded yoke periphery, baseplane, interior inclined-plane and pawl pole periphery during cold-extruded, and cold-extruded magnet locating surface and magnet support face.
Forging step divides three operations successively: pier base → blocking → finish forge, adopts hot forging to manufacture blank, arrange a capaciting material groove during finish forge at magnet locating surface and intersection, magnet support face during blocking;
Frequency Induction Heating is adopted during heating.
Adopt fervent or cold-cutting process during trimming, remove forging overlap.
Between trimming and ball blast, increase magnetic annealing operation, during magnetic annealing, forging is put into annealing furnace and anneal.
Locate with baseplane during right boring endoporus, with scroll chuck clamping yoke periphery, Vehicle Processing pawl pole periphery, fan plane, right boring endoporus and Milling Machining positioning spline, guarantee that the axiality of pawl pole periphery and endoporus is 0.02mm, and the perpendicularity of fan plane and endoporus is 0.03mm.
With fan plane positioning during car yoke end face, with scroll chuck gripper jaw pole periphery, Vehicle Processing yoke end face, guarantee that the depth of parallelism between yoke end face and fan plane is 0.03mm.
Beneficial effect: the invention solves the defect existed in background technology, adopt forge hot to add cold-extruded technique, the cut mode before replacing processes magnet groove, greatly enhances productivity.Rough forging design capaciting material groove, the material extruded when extruding magnet support face and magnet locating surface can flow in capaciting material groove, thus can flow stress be reduced, improve Life of Die for Extruding Aluminium Alloy, also can ensure that pawl pole finished product is no more than 0.5mm at the fillet α radius of magnet support face and magnet locating surface intersection with comparalive ease simultaneously.
