Abstract
The invention relates to a 6MW doubly-fed wind generator stator and rotor lamination full-piece edge trimming and blanking technology, which specifically comprises a stator and rotor lamination punching process which comprises the steps of installing a prepared rotor lamination punching die on a press, adjusting the equipment, coating a proper amount of lubricating oil on the cutting edge, starting the press and sequentially performing repetitive die shaft hole punching on a tidily cut silicon steel sheet to obtain a stator and rotor lamination blank with a positioning shaft hole; a stator and rotor lamination full-piece edge trimming and blanking process for obtaining a stator and rotor lamination which is subjected to full-piece edge trimming and blanking; a stator and rotor separation process and a stator slot machining process for obtaining a rotor lamination and a stator lamination with the stator slot which are separated from each other. On the premise that the press is not replaced by a larger press, the stator and rotor lamination full-piece edge trimming and blanking is finished, and the equipment cost, the machining expense and the like are reduced.
Description
Technical field
The present invention relates to a kind of punching full wafer trimming punching process, relate in particular to a kind of 6MW double-fed wind power generator stator and rotor punching full wafer trimming punching process.
Background technology
Along with the aggravation of global energy anxiety and environmental pollution, a kind of sustainable development and free of contamination new forms of energy are all actively being found in countries in the world.Wind power generation is with its clean, pollution-free, short construction period, and the advantage such as operation cost is low, has now become the first-selection that global evolution is utilized new forms of energy and renewable green energy resource.For high-power wind turbine unit, due to main force's type that double-fed wind power generator is little with little, lightweight, the required Converter Capacity of its volume, power supply quality high becomes large-scale wind driven generator.China is for Large-scale Wind Turbines, and particularly the policy support of MW grade wind driven generator equipment and the market demand, make large-scale wind power plant be developed rapidly at home and apply.
6MW double-fed wind power generator is according to designing requirement, and model is decided to be YSKS710L3-6.YSKS710L3-6 wind-driven generator type is more much bigger than conventional wind-driven generator, and therefore the design for stator and rotor certainly will will cause its punching radius to surpass the conventional generator of producing.Because the maximum punching press scope of the forcing press generally using in middle and small motor factory cannot meet the punching radius requirement of 6MW double-fed wind power generator, so cannot use multiple stamping to carry out full wafer excision to it.
Summary of the invention
The invention provides a kind of 6MW double-fed wind power generator stator and rotor punching full wafer trimming punching process, do not changing under the prerequisite of larger forcing press, complete stator and rotor punching full wafer trimming stamping-out.
For achieving the above object, concrete technical scheme of the present invention is as follows:
6MW double-fed wind power generator stator and rotor punching full wafer trimming punching process, concrete steps are as follows:
A, stator and rotor punching punch process
A1, ready rotor punching perforating die is installed on forcing press, adjustment equipment is smeared moderate lubrication oil at cutting edge, starting pressure machine simultaneously;
A2, by cutting out regular silicon steel sheet, carry out successively multiple stamping axis hole blanking, obtain one with the stator and rotor punching blank of positioning shaft hole;
B. stator and rotor punching full wafer trimming stamping-out
B1, the stator outer diameter single-die punch of making is arranged on notching press and calibrating position, at cutting edge, smears appropriate lubricating oil simultaneously;
B2, the good stator and rotor punching blank with positioning shaft hole of stamping-out is fixed on notching press, guarantees the consistency of processing;
B3, startup notching press, after fortune circles, obtain the stator and rotor punching after full wafer trimming stamping-out.
C. stator and rotor separation process and the stator rabbet course of processing
C1, the stator punching single-die punch made is installed and calibrating position, at cutting edge, smeared appropriate lubricating oil simultaneously;
C2, the stator and rotor punching with positioning shaft hole that stamping-out is got off are arranged on notching press, guarantee the consistency of processing;
C3, start notching press, after fortune circles, obtain rotor punching after separation and with the stator punching of stator slot.
Beneficial effect of the present invention is: do not changing under the prerequisite of larger forcing press, this technique has guaranteed that workpiece can meet product design requirement, has reduced equipment cost and processing charges etc.
