Description
Technical field
The invention belongs to die casting technical field, relate to a kind of mould for the manufacture of automobile generator claw pole.
Background technology
Along with the development of society, the raising of people's living standard, automobile becomes the main walking-replacing tool of people's trip gradually, the requirement of people to car comfort is also more and more higher, existing automobile generally adopts the electric elements such as air-conditioning, automatically controlled vehicle window, electronic barbed chair, power consumption sharply rises, also more and more higher to the requirement of generator power, for this reason, people have invented claw pole electric generator, mosaic magnet between pawl pole before and after generator, greatly increases the magnetic property of pawl pole, thus greatly increases power output and the efficiency of generator.
Existing generator claw pole, such as Chinese patent literature data discloses the processing technology [application number: 201210145579.1 of hybrid excitation generator pawl pole; Application publication number: CN103386586A], this generator claw pole is formed by following steps manufacture, a, hot finish forge or warm forging manufacture technics pawl pole blank; B, magnetic annealing; C, cold-finish; D, brill endoporus; E, right boring endoporus; F, car yoke end face; The magnet standing groove of pawl two sides is erected in g, milling.
The generator claw pole of this kind of structure comprises base plate, the edge of base plate is evenly equipped with six or eight perpendicular pawls, the middle of base plate is also provided with yoke, base plate and yoke are integral structures, perpendicular pawl and yoke are positioned at the same side of base plate, mill out by milling cutter to the magnet standing groove that magnet positions, namely lacking corresponding mould pawl pole blank is shaping processes afterwards to magnet standing groove, and the pawl pole of this kind of structure completes a processing and needs to carry out to cut for 12 times or 16 times magnet standing grooves, process a pawl pole and need the longer time, waste time and energy, working (machining) efficiency is low, and in process, be difficult to the uniform wall thickness ensureing magnet standing groove both sides magnetic muscle, uniformity is poor, and namely magnet is placed on after in this magnet standing groove, when rotation, there is the problem loosened in magnet, poor stability, claw pole electric generator generating efficiency is low.
Summary of the invention
The object of the invention is for the above-mentioned problems in the prior art, provide a kind of mould for the manufacture of automobile generator claw pole, use this mould can extrude magnetic muscle, solve and how to make existing magnetic muscle uniform wall thickness, uniformity good, working (machining) efficiency is high.
Object of the present invention realizes by following technical proposal: a kind of mould for the manufacture of automobile generator claw pole, comprise upper die and lower die, it is characterized in that, inner after described upper die and lower die fit have the cavity with the pawl pole mating shapes of band magnetic muscle, yoke, the center of described counterdie vertically has the lower through-hole run through, be provided with material returned traveller in described lower through-hole, the described upper surface of material returned traveller and the bottom surface of yoke match.
After pawl pole blank is made, blank is placed in cavity, shape, the area of the shape of the upper surface of material returned traveller, area and yoke bottom surface are substantially identical, can make according to actual needs to there is between material returned traveller and yoke certain gap or the upper surface of material returned traveller and the bottom surface of yoke are fitted, force value when certain gap can reduce extruding is set, make this mould extrude magnetic muscle laborsaving, the dimensional accuracy that pawl pole is processed of fitting in the bottom surface of the later stage upper surface and yoke that arrange material returned traveller of processing is high; By extrusion die, make the metal flow in blank, extrude magnetic muscle, make magnetic muscle precisive shaped, make the uniform wall thickness of magnetic muscle, uniformity good by Making mold magnetic muscle, working (machining) efficiency is high.
A kind of for the manufacture of in the mould of automobile generator claw pole, the top of described counterdie has gathering sill above-mentioned, and the bottom of described gathering sill and patrix matches.Guide effect is played in the movement of gathering sill to patrix, and make this mould when processing magnetic muscle, the position of patrix can not offset, and namely the shape of cavity can not be out of shape, and the pawl pole processed, the dimensional accuracy of magnetic muscle are high, and qualification rate is high.
Above-mentioned a kind of for the manufacture of in the mould of automobile generator claw pole, the upper edge place of described lower through-hole has annular table terrace.The upper surface area of annular table terrace is little, the area of material returned traveller upper surface adds that the upper surface area of annular table terrace is identical with the area of yoke bottom surface, add man-hour, edge, yoke bottom surface is resisted against on annular table terrace, annular table terrace has yoke is played to the effect of locating, supporting the man-hour that adds in gap between material returned traveller and yoke, ensure that yoke can not excessively move down, improve machining accuracy.
Above-mentioned a kind of for the manufacture of in the mould of automobile generator claw pole, described cavity comprises the shaping place of magnetic muscle and the shaping place of perpendicular pawl, the described shaping place of magnetic muscle is cambered surface away from the lateral surface of yoke, and be the side of same cylinder away from the lateral surface of yoke with the shaping place of perpendicular pawl, the described shaping place of magnetic muscle and the disjunct end face in the shaping place of perpendicular pawl are plane, the end face at the described shaping place of magnetic muscle and the shaping place of magnetic muscle away from yoke lateral surface between rounding, end face and the shaping place of the magnetic muscle rounding between the medial surface of yoke at the described shaping place of magnetic muscle.The shaping place of magnetic muscle of this kind of shape enables the metal in blank flow in the shaping place of magnetic muscle more smoothly, metal is made to be crowded with shaping places of magnetic muscle, be mainly used in making magnetic hypertrophy of tendon and muscle shaping, use the shaping place of magnetic muscle of this kind of shape, the pressure needed during extruding is larger, during extruding, between material returned traveller and yoke, vacate certain gap, to reduce required pressure.
