Abstract
The invention discloses a method for machining motor stator and rotor sheets, which comprises the following steps of: blanking a stator sheet blank with an inner hole of phi 67.7 and a rotor sheet blank with an outer diameter of phi 67.7 through a composite blanking die for the stator and rotor sheets on a bar stock with a certain width; performing notch stamping and inner hole trimming combination on the stator sheet blank to form the stator sheet; punching notches on the rotor sheet blank to machine the rotor sheet; performing die casting and axial compression on the rotor sheet to form a rotor axial compression piece, wherein the dimension of an excircle of the rotor die-casting piece is phi 67.7; and directly performing finish turning machining on the rotor die-casting piece to obtain an outer diameter in given dimension. Compared with the traditional machining method, the rotor die-casting piece can be directly subjected to the finish turning machining to have the outside diameter dimension required by the design, the rough machining process is saved, the working time is saved, the working efficiency is greatly improved, and the product quality is guaranteed.
Description
Technical field: the present invention relates to motor, particularly relate to the processing method of a kind of motor stator, rotor sheet.
Background technology: in the household electrical appliance industry, use a large amount of asynchronous machines, when producing this class motor, need a large amount of stator of punch process, rotor sheet, to make stator and rotor assembly, along with high velocity ram machine equipment and the development of progressive die continuously, there is the high velocity ram machine of employing to join continuous progressive die at present to fixed, rotor sheet carries out punch process, but because of equipment and mold costs an arm and a leg, at many kinds, the market demand incompatibility of small lot, more motor stator, rotor sheet still adopts the processing of common punch press substep stamping-out, the conventional electric machine stator, the processing method for stamping of rotor sheet is: stator piece, the compound blanking of rotor sheet, the stator piece jet-bedding, three step of rotor sheet jet-bedding processing method.Stator piece internal diameter after the processing is identical with the basic size of rotor sheet external diameter, for example: stator piece internal diameter basic size is φ 68, and then rotor sheet external diameter basic size is φ 68, and rotor sheet is behind die casting, last item, the outer cylinder surface of motor rotor die-casting spare is lathed the outside dimension of degree of precision, for example turning is to φ 67.5 ± 0.015, but the outer cylinder surface φ 68 of motor rotor die-casting spare needs through rough turn to φ 67.7, finish turning is to φ 67.5 then, finish the turning operation in two steps, operation is many, long processing time.
Summary of the invention: purpose of the present invention is exactly that a kind of new motor stator, the processing method of rotor sheet will be provided, and it can overcome the existing problem of above processing.The object of the present invention is achieved like this, the processing method of motor stator, rotor sheet, it is characterized in that: the first step is on the certain width billot, earlier by stator piece, the compound blanking die of rotor sheet, stamping-out goes out the rotor sheet blank that blank that the stator piece endoporus is φ 67.7 and external diameter are φ 67.7; Second step was to carry out jet-bedding and endoporus side cut Compound Machining goes out stator piece on the stator piece blank; The 3rd step was to carry out jet-bedding to process rotor sheet on the rotor sheet blank; The 4th the step be rotor sheet through being cast into motor rotor die-casting spare, die casting becomes rotor last item spare behind last item, motor rotor die-casting spare external cylindrical surface basic size is φ 67.7; The 5th step was that motor rotor die-casting spare directly carries out the external diameter that finish turning is processed into given size.The size of stator piece of the present invention, rotor sheet is guaranteed by mould, the work step and the time of processing punching are compared with traditional processing method, can directly carry out finish turning behind the motor rotor die-casting spare and be processed into the desired outside dimension of design, saved the roughing operation, saved the operating time, improve operating efficiency greatly, guaranteed product quality.
