Similarly, the second elastic member 59 is located between the second slider 57 and the frame 60, and the second slider 57 is subjected to the elastic force exerted by the second elastic member 59. The first elastic element 58 and the second elastic element 59 are identical in specification and are both return springs, so that the first shaping element 51 and the second shaping element 52 are prevented from being locked in the moving process through the floating design of the first elastic element 58 and the second elastic element 59, and meanwhile, the first shaping element 51 and the second shaping element 52 are kept to be in the same displacement, and the purpose of synchronous displacement of the first shaping element 51 and the second shaping element 52 is achieved.

The first shaping piece 51 is provided with a first guide slot 511 matched with the central limiting piece 70; the second shaping member 52 is provided with a second guiding slot 521 which is matched with the center limiting member 70. The groove shape of the first guide groove 511 matches with the outline of the center limiting member 70, and the first guide groove 511 and the center limiting member 70 are matched to guide and center the first shaping member 51, so that the first shaping member 51 is ensured to be accurately positioned when the stator core 20 is extruded. Similarly, the second guiding slot 521 cooperates with the center stopper 70 to ensure that the second shaping member 52 is accurately positioned when pressing the stator core 20.

Specifically, the central limiting member 70 is a rectangular parallelepiped with a square cross section, and at least one diagonal line of the square is parallel to or coincident with the symmetry axis of the stator core 20; the first guide groove 511 and the second guide groove 521 are both triangular grooves, that is, the first guide groove 511 and the second guide groove 521 are both isosceles triangular grooves.

The stator core shaping device of the embodiment is matched with the conveying line, the automation degree is high, the tooling plate 10 is automatically ejected, shaped and then falls back only through the positioning mechanism 30, the tooling plate 10 comprises two states of a shaping state and a conveying state, and when the tooling plate 10 is ejected, the tooling plate 10 is static, so that the stator core 20 can be conveniently shaped and is in the shaping state; when the tooling plate 10 falls back to the conveying line, the tooling plate 10 flows along with the conveying line, and the tooling plate 10 is conveyed to the next station and is in a transportation state. The shaping process of the stator core 20 can be better matched with a conveying line, so that the working efficiency is improved, and the labor intensity of workers is reduced; and the phenomena of out-of-roundness, warping deformation, deflection and the like of the iron core after the stator iron core 20 is assembled are avoided, and the assembling yield of the stator iron core 20 is improved.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.
