Description

The coil cylindrical sizing die of the final trimmer of stator

[technical field]

The utility model relates to the coil cylindrical sizing die of the final trimmer of a kind of stator, belongs to the motor stator coil reshaping technical field.

[background technology]

Motor stator is made up of iron core and the coil that is wrapped on the iron core, owing to expose in tip circle and circular portion coil outer ring after bulging, the end of iron core irregular, all must carry out shaping, to guarantee the specification and the size of coil by the coil cylindrical shaping mould of the final trimmer of stator.

Please refer to shown in Figure 1, because patrix is identical with the shape and the specification of counterdie, now only be example with the counterdie: the following outer circle of embracing of this sizing die counterdie is that the outer iron 4 ' of embracing is encircled into half O-ring structure under four arcs, outside down, embrace the mode that circle is held tightly, realization places down outer stator coil reshaping requirement of embracing in the circle, simple in structure, easily manufactured, anatomize said structure and be not difficult to find that there is following shortcoming in it:

Four blocks of lower outside armful of iron 4 ' are in the process of holding tightly, owing to have the gap between adjacent two blocks of lower outside armful of iron 4 ', the enamel-covered wire of this gap location wears away enamel-covered wire paint easily when being held tightly, cause the coil electric leakage, especially the copper factor height of stator coil, enamel-covered wire be again thicker, hard words just the easier enamel-covered wire that occurs fall lacquer, even the problem such as scuffing.

[utility model content]

The deficiency that the utility model exists at above-mentioned prior art and the coil cylindrical sizing die of the final trimmer of a kind of stator is provided, can solve the shaping problem of high copper factor, thick and stiff enamelled wire stator coil by this sizing die, reach to reduce and occur the purpose that enamelled wire falls lacquer, damage in the shaping process.

For solving the problems of the technologies described above, the utility model provides following technical scheme:

A kind of coil external circle shaping die of final stator shaping machine, formed by counterdie and patrix, counterdie comprises lower sliding block seat, is slidingly installed in the sliding block of lower sliding block seat, lower skateboard and places the lower skateboard end face and be fixed in the lower circle holding of sliding block, lower circle holding is surrounded by four blocks of lower outside armful of iron and is formed, and has the gap between the adjacent lower outside armful of iron, patrix comprises the top shoe seat, is slidingly installed in the top shoe of top shoe seat, upper slide and places the upper slide end face and be fixed in the upper circle holding of top shoe, upper circle holding is surrounded by four blocks of upper outside armful of iron and is formed, and has the gap between the adjacent upper outside armful of iron.Improvement of the present utility model is: two lower outside armfuls of iron adjacents are by being provided with arms circle iron, the plane that two outsides of this time arms circle iron have the respectively inner side plane corresponding with adjacent two lower outside armfuls of iron is affixed, the inboard of lower arms circle iron all has the curved surface of same curvature, between adjacent twice arms circle irons and the curved surface that has at the inboard pars intermedia of lower outside armful of iron equate that with lower arms circle iron inner curve curvature four curved surfaces of lower outside armful of iron consist of a locus circle together with four curved surfaces of lower arms circle iron; Two upper outside armfuls of iron adjacents are by being provided with arms circle iron on, the plane that two outsides that should upper arms circle iron have the respectively inner side plane corresponding with adjacent two upper outside armfuls of iron is affixed, the inboard of upper arms circle iron all has the curved surface of same curvature, on adjacent two between the arms circle iron and the curved surface that has at the inboard pars intermedia of upper outside armful of iron equate that with upper arms circle iron inner curve curvature four curved surfaces of upper outside armful of iron consist of a locus circle together with four curved surfaces of upper arms circle iron.

The end of every lower arms circle iron connects an extension spring, the other end of extension spring then be fixed in lower skateboard on a screw link to each other; The end of every upper arms circle iron connects an extension spring, the other end of extension spring then be fixed in upper slide on a screw link to each other.

The utlity model has following beneficial effect:

Because upper, on counterdie has been set up respectively, lower arms circle iron, so that on, when the slide block of counterdie is drawn close to the center under the ramp effect of take-up housing, on, lower outside circle holding produces holds motion tightly, and on, lower arms circle iron again all the time with corresponding on, lower outside circle holding is close to mutually, on, lower outside circle holding just the gap can not occur in the process of holding tightly, on, lower outside circle holding all can form a diminishing ring seal effect, so just solved cleverly the enamel-covered wire scuffing, fall the problem of lacquer, adapt to high copper factor fully, thick and stiff wire diameter enamelled wire stator coil external circle shaping needs, reduce the defect rate that occurs in the production process, strengthened the adaptive faculty of the utility model in the coil shape shaping.
