Abstract
The invention discloses a method for machining a stator piece and a rotor piece of the motor, which comprises that: on a strip material with a certain width, a stator piece blank with an inner hole of phi 68 and a rotor piece blank with an outer diameter of phi 68 are punched by a stator and rotor piece composite blanking die; the rotor piece blank is subjected to groove punching and outer diameter trimming to be compositely machined into the rotor piece; the stator piece blank is subjected to groove punching to be machined into the stator piece; the rotor piece is subjected to die-casting and shaft pressing to form a rotor shaft pressing piece of which the excircle size is phi 67.7; and the rotor die-cast piece is directly subjected to finish turning to be machined to have the outer diameter with required outer diameter. Compared with the traditional machining method, the method has the advantages of reducing a rough machining procedure, saving machining time, improving work efficiency and ensuring product quality.
Description
Technical field: the present invention relates to a kind of stator of motor, the processing method of 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 is fixed, rotor sheet still adopts the processing of common punch press substep stamping-out, the stator of conventional motors, the processing method for stamping of rotor sheet is: stator, the compound blanking of rotor sheet, the stator piece jet-bedding, the three steps processing of rotor sheet jet-bedding.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, then rotor sheet external diameter basic size is φ 68, 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 need through rough turn to φ 67.7 then finish turning finish the turning operation in two steps to φ 67.5.
Summary of the invention: purpose of the present invention is exactly that a kind of stator of motor, the processing method of rotor sheet will be provided.The object of the present invention is achieved like this, a kind of stator of motor, the processing method of rotor sheet, it is characterized in that: the first step is on the certain width billot, earlier by stator, the compound blanking die of rotor sheet, stamping-out goes out the rotor sheet blank that blank that the stator piece endoporus is φ 68 and external diameter are φ 68; Second step was to carry out jet-bedding and external diameter side cut Compound Machining goes out rotor sheet on the rotor sheet blank; The 3rd step was to carry out jet-bedding to process stator piece on the stator piece blank; Rotor sheet is through being cast into motor rotor die-casting spare, and die casting becomes rotor last item spare behind last item, and motor rotor die-casting spare external cylindrical surface basic size is φ 67.7, and motor rotor die-casting spare directly carries out the outside dimension that finish turning is processed into designing requirement.The size of stator of the present invention, rotor sheet is guaranteed that by mould the work step and the time of processing punching are compared with traditional processing method, and it has reduced the roughing operation, has saved process time, has improved operating efficiency, has guaranteed product quality.

Embodiment:
A kind of stator of motor, the processing method of rotor sheet is characterized in that: the first step is on the certain width billot, and earlier by stator, the compound blanking die of rotor sheet, stamping-out goes out the rotor sheet blank that blank that the stator piece endoporus is φ 68 and external diameter are φ 68; Second step was to carry out jet-bedding and external diameter side cut Compound Machining goes out rotor sheet on the rotor sheet blank; The 3rd step was to carry out jet-bedding to process stator piece on the stator piece 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 outside dimension that finish turning is processed into designing requirement.
