Description
Technical field: the utility model relates to a kind of stator piece jet-bedding and endoporus side cut compound die of motor.
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 stator piece, 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 slice, rotor sheet still adopts the processing of common punch press substep stamping-out, the stator piece of conventional motors, the processing mold of rotor punching is: stator, the compound blanking die of rotor, stator piece jet-bedding mould, rotor sheet jet-bedding mould.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, then the basic size of the internal diameter of the external diameter of drift and die is φ 68, rotor sheet after the processing is through die casting, behind the 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 to φ 67.5, finish the turning operation in two steps, operation is many, and the operating time is long, and efficient is low.
Summary of the invention: the purpose of this utility model is exactly stator piece jet-bedding and the endoporus side cut compound die that a kind of motor will be provided, and it can overcome the existing problem of above product well.The purpose of this utility model is to realize like this, the stator piece jet-bedding of motor and endoporus side cut compound die, formed by punch 1, punch 4, lower die, it is characterized in that: the central authorities of mould are provided with punch 4, cylindrical basic size is that the uniform groove internal diameter basic size of φ 68,24 grooves is φ 67; Be provided with punch 1, punch 2 around the punch 4, described punch 1, punch 2 design by the flute profile of corresponding stator piece, and the flute profile of pressing stator piece circumferentially, and the internal diameter basic size of punch 1, punch 2 is φ 67; The outer ring of punch 1, punch 2 is provided with the punch 3 by the flute profile design of corresponding stator piece; Be provided with lower die with punch 1, punch 2, punch 3, punch 4 corresponding belows, the basic size of described lower die endoporus is φ 68; Other mould accessory of the die backing plate of a whole set of mould, die edge cover, punch retainer, punch stripper, upper padding plate, lower bolster, top mold frame, following mould bases, following mould bases guide pillar, top mold frame guide pin bushing only need be supporting with relevant punch and die by general manufacture method.The work step and the time of the utility model processing punching are compared with traditional processing, have saved rough turn operation, have saved the time, have improved operating efficiency greatly.

1. punch 1, and 2. punch 2, and 3. punch 3, and 4. punch 4,5. lower die.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing:
The stator piece jet-bedding of motor and endoporus side cut compound die are made up of punch 1, punch 4, lower die 5, and it is characterized in that: the central authorities of mould are provided with punch 4, and cylindrical basic size is that the uniform groove internal diameter basic size of φ 68,24 grooves is φ 67; Be provided with punch 1, punch 2 around the punch 4, described punch 1, punch 2 design by the flute profile of corresponding stator piece, and the flute profile of pressing stator piece circumferentially, and the basic size of punch 1, punch 2 internal diameters is φ 67; The outer ring of punch 1, punch 2 is provided with the punch 3 by the flute profile design of corresponding stator piece; Be provided with lower die with punch 1, punch 2, punch 3, punch 4 corresponding belows, the basic size of described lower die endoporus is φ 68; Other mould accessory of the die backing plate of a whole set of mould, die edge cover, punch retainer, punch stripper, upper padding plate, lower bolster, top mold frame, following mould bases, following mould bases guide pillar, top mold frame guide pin bushing only need be supporting with relevant punch and die by general manufacture method.During concrete enforcement, mould after heat treatment must meet above-mentioned dimensional requirement.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 67.7 and external diameter are φ 67.7; On the stator piece blank, carry out jet-bedding and endoporus side cut compound die processes the stator piece that internal diameter is φ 68; Carrying out jet-bedding on the rotor sheet blank, to process external diameter be φ 67.7 rotor sheets, and whole punch process finishes.The size of stator piece, rotor sheet is guaranteed by mould, rotor sheet is 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, motor rotor die-casting spare can directly carry out the external diameter that finish turning is processed into given size, and for example turning is to φ 67.5 ± 0.015.Reduce the roughing operation, saved process time, improved efficient.
