Abstract
Provided is a split-type stator overlying mold. The split-type stator overlying mold comprises a pull bar. The pull bar is connected with an expanding core. The expanding core is connected with a split-type expanding tire. The bottom of the split-type expanding tire is connected with a lower pressing plate. The lower pressing plate is used for placing stator punching sheets. An upper pressing plate is arranged on the stator punching sheets. A positioning protruding point is arranged on the split-type expanding tire. When the mold works, a hydraulic device pulls the pull bar downwards. The pull bar goes downwards to drive the expanding core to move downwards. Because of the inclined plane between the expanding core and the split-type expanding tire, the expanding core moves downwards and opens the split-type expanding tire. The opened expanding core can tidy the stator punching sheets, and the tidiness of the stator punching sheets is raised. The split-type stator overlying mold adds the positioning protruding point, rotation and deformation of the stator punching sheets during the overlying process are prevented, and the quality of the stator punching sheets are raised.
Description
Technical field
The utility model belongs to technical field of mold, relates in particular to a kind of split type stator laminating die.
Background technology
The core that rises that existing laminating tool generally comprises expander and matches with expander, but existing expander is integral type, the core that rises is inserted in the process of expander, and expander can not carry out corresponding expansion and adjust, easily cause the distortion of product, the position adjustment of all-in-one-piece expander is also inconvenient; And owing to adopting hydraulic test, pulling force is larger, easily make the punching in stator core produce displacement, affect stator core and laminate quality.
Utility model content
The utility model is mainly to solve the existing technical problem of above-mentioned prior art, a kind of split type stator laminating die is provided, by pull bar is set, core and split type expander rise, utilize pull bar will rise by core toward drop-down, due to the inclined-plane rising between core and split type expander, the core that rises can strut split type expander, and the expander strutting can be neat by stator punching, increases the regularity of stator punching; And split type stator laminating die increased positioning convex point, prevent stator punching rotational deformation in lamination process, increase the quality of stator punching.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of split type stator laminating die, comprise pull bar, described pull bar is connected with the core that rises, described in the core that rises be connected with split type expander; Described split type expander bottom is connected with lower platen, and described lower platen is used for placing stator punching, on described stator punching, top board is set, and for stator punching is compressed, prevents that stator punching is out of shape in lamination process, sideslip.
As preferably, on described split type expander, positioning convex point is set, prevent stator punching rotational deformation in lamination process.
As preferably, described split type expander is comprised of three expander moulds.
The beneficial effect the utlity model has: by pull bar is set, core and split type expander rise, utilize pull bar will rise by core toward drop-down, due to the inclined-plane rising between core and split type expander, the core that rises can strut split type expander, the expander strutting can be neat by stator punching, increases the regularity of stator punching; And split type stator laminating die increased positioning convex point, prevent stator punching rotational deformation in lamination process, increase the quality of stator punching.Therefore the utlity model has the features such as simple in structure, reasonable in design.

In figure: 1, pull bar; 2, the core that rises; 3, split type expander; 4, top board; 5, stator punching; 6, lower platen; 7, hydraulic test; 8, positioning convex point; 9, stator punching.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of split type stator laminating die, as depicted in figs. 1 and 2, comprise pull bar, described pull bar is connected with the core that rises, described in the core that rises be connected with split type expander; Described split type expander bottom is connected with lower platen, and described lower platen is used for placing stator punching, on described stator punching, top board is set, and on described split type expander, positioning convex point is set, and described split type expander is comprised of three expander moulds.
During work, as shown in Fig. 3～5, stator punching is placed between lower platen and top board, then hydraulic test by pull bar toward drop-down, under pull bar, be about to drive the core that rises down to move, due to the inclined-plane rising between core and split type expander, rise core down athletic meeting split type expander is strutted, the expander strutting can be neat by stator punching, increases the regularity of stator punching; And split type stator laminating die increased positioning convex point, prevent stator punching rotational deformation in lamination process, increase the quality of stator punching.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all should think and belong to protection range of the present utility model.
