Description
Technical field
The present invention relates to a kind of red edge-cutting manufacture technology of automobile generator finish forging claw pole.
Background technology
Modern Car generally adopts air-conditioning, BBG, and automatically controlled door and window, electric elements such as electronic barbed chair, power consumption sharply rises.Alternating current generator is the critical component of automobile, is responsible for the power supply of automobile, and the configuration difference of car, power consumption demand are just different, and generator is just different, and the corresponding pawl utmost point is just different.Alternating current generator is installed in the next door of engine, by the engine driven rotary, thereby mechanical energy is converted into electric energy.Alternating current generator is made up of stator winding and rotor winding two parts, and the threephase stator winding is distributed on the housing by differing 120 degree each other, and the rotor winding is made up of two pawl utmost points.By excitation, two pawl utmost points form the N utmost point and the S utmost point when the rotor winding is connected direct current.The magnetic line of force is set out by the N utmost point, enters stator core through the air gap and returns the adjacent S utmost point.Rotor is in case rotation, and the rotor winding will cutting magnetic line, produces the electromotive force of mutual deviation 1 20 degree in stator winding, and promptly three-phase alternating current becomes direct current output through rectifier cell again.The motorcar alternator pawl utmost point is the main element that is used for forming rotating excitation field, and its shape and electromagnetic performance directly influence the induct waveform of AC electromotive force and the generating capacity and the noise of alternating current generator.
At present, the common process of domestic production claw pole for automobile generator is as follows:
1. hot investment casting: thus the as easy as rolling off a log generation shrinkage cavity of the pawl of this explained hereafter, loosen, be mingled with and defective such as chemical composition instability causes magnetic resistance to increase, electromagnetic performance is poor, thereby influence the power of generator, can't adapt to current automobile current generator volume will dwindle, the development trend that power will increase, and casting readily produces hard spot, is difficult for machined.
2. Sheet Metal Forming Technology: this technology must be used large-scale forging equipment, and early investment is bigger, and this technology can not produce the pawl utmost point of band yoke, must join a yoke in addition, thereby produce the assembling air gap, and magnetic resistance increases, and influences generator power.
3. hot forging adds fine-processing technique: Chinese patent CN1069853C discloses a kind of forming process for pawl pole of automobile generator, comprise raw material blanking, open type hot forging, cut overlap, enclosed hot forging, fine finishining, surface lubrication processing etc., the mode that this process using hot forging and fine finishining combine, the claw pole for automobile generator chemical analysis of producing is stable, no shrinkage cavity, slag blister etc.But this technology needs twice heating, and production cost is higher.
4. side cut operation, what adopted in the past is cold-trim(ming) technology, and the product temperature behind the finish forge has 900 to 1000 degree, and product must install to earlier in the circulation case, after treating that product cools off fully, again product is poured out side cut, the consequence that causes is: 1), and vanning when finish forge is, mould turnover during side cut, the product circulation time is long, and product is damaged seriously, the logistics cost height; 2), product shear strength height during cold-trim(ming), shearing force is big, causes device damage serious, the maintenance cost height; 3), noise is big during cold-trim(ming).
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of red edge-cutting manufacture technology of claw pole for automobile generator, not only equipment investment is little for this technology, the end product quality height of forging, and can reduce production costs.With the pawl utmost point of the present invention, the alternating current generator AC electromotive force of inducting is similar to sinusoidal waveform, and the generated output of alternating current generator is big, is applicable to each big automobile current generator.
The technical solution adopted for the present invention to solve the technical problems is: a kind of red edge-cutting manufacture technology of automobile generator finish forging claw pole has following processing step:
A. blanking;
B. heat: raw pieces is dropped into be heated to 1150 ℃～1200 ℃ in the heating furnace;
C. jumping-up:, remove surface scale the raw pieces that the heats thick part in flat one-tenth emblem of upsetting;
D. blocking: jumping-up spare is moved into preformed in the blocker of taking pore out of, adopt pawl to forge towards upper type, form pre-forging, pre-forging planform is: have base plate, on base plate, be evenly distributed with six or eight beak shaped pawls, be provided with a yoke in the middle of the base plate;
E. finish forge: pre-forging is put into the precision forging die moulding, form finish forge spare, finish forge spare planform is: have base plate, on base plate, be evenly distributed with six or eight beak shaped pawls, be provided with a yoke in the middle of the base plate, on the circumference of yoke, be evenly distributed with six or eight insulated paint drainage troughs, on the bottom that magnetic is gripped, be distributed with the wire casing of drawing of six or eight coil anti-rotation projections and six or eight insulated wires;
F. red side cut: the product behind the finish forge directly circulates by conveyer belt on the operating platform of red side cut equipment, the operative employee clamps product with pliers and puts into edger and excise overlap, this moment, the temperature of product reached 950 ℃～1050 ℃, the product of excision overlap flows directly in the circulation case by conveyer belt, and overlap flows in the ash can;
G. magnetic annealing: the finish forge spare that will excise overlap is put into annealing furnace and is annealed;
H. cold shaping: inclined-plane in yoke cylindrical, inner plane and the pawl of the whole pawl utmost point, for subsequent fine processing provides benchmark;
I. fine finishining: the pawl utmost point after the cold shaping is carried out machined, make finished product.
The invention has the beneficial effects as follows that make the alternating current generator AC electromotive force of inducting be similar to sinusoidal waveform with the pawl utmost point of the present invention, the generated output of alternating current generator is big, is applicable to each big automobile current generator.In addition, adopt red trimming technology, make heating, jumping-up, blocking, finish forge and red side cut totally five operations formation streamlines production, reduced logistics cost, and, the temperature of product reaches 950 ℃～1050 ℃ during red the side cut, this moment, the shear strength of material was low, had reduced the tonnage of equipment greatly, the service life of having improved equipment, thereby reduced production cost, reduced noise.Because finish forge and red side cut operation composition production line, make the product appearance quality behind the finish forge obtain effective control, thereby improved product quality.
