The invention discloses a continuous hinge circle-rolling device which comprises an upper die and a lower die, wherein an end circle-rolling punch, a root circle-rolling punch, a 45-degree circle-rolling punch and a circle-rolling forming punch are sequentially arranged at the bottom of the upper die at intervals; an end circle-rolling block, a root circle-rolling block, a 45-degree circle-rolling block and a circle-rolling forming block, which respectively correspond to the end circle-rolling punch, the root circle-rolling punch, the 45-degree circle-rolling punch and the circle-rolling forming punch, are arranged on the lower die; the end circle-rolling punch, the root circle-rolling punch, the 45-degree circle-rolling punch and the circle-rolling forming punch are fixedly connected with the upper die through bolts respectively; the end circle-rolling block, the root circle-rolling block and the 45-degree circle-rolling block are fixedly connected with the lower die through bolts, and the circle-rolling forming block is movably connected to the lower die. The continuous hinge circle-rolling device can simultaneously carry out end circle-rolling, root circle-rolling, 45-degree circle-rolling and circle-rolling forming for four hinges respectively, can automatically move to the next process, achieves the purpose of automatic, efficient and precise continuous circle-rolling, and is high in precision and high in production efficiency.

The method includes a step of aligning and laminating enlarged iron core pieces including iron core pieces and dummy piece parts and forming a composite laminated iron core integrally including a dummy laminated part with the dummy piece parts laminated and a laminated iron core, a step of placing and positioning the composite laminated iron core on a jig and removing the dummy laminated part, and a step of mutually bonding the laminated iron core body with the dummy laminated part removed to form the laminated iron core.

A polishing apparatus comprises a first polishing table having a first polishing surface, a substrate carrier for holding a substrate and positioning the substrate so as to bring a surface of the substrate into contact with the first polishing surface, a pressing mechanism for pressing, against the first polishing surface, the surface of the substrate which has been brought into contact with the first polishing surface by the substrate carrier, a retainer ring mounted on the substrate carrier so as to surround the substrate which has been pressed against the first polishing surface by the pressing mechanism, and a retainer-ring-position-adjustment mechanism for adjustably positioning the retainer ring relative to the substrate, which has been pressed against the first polishing surface, in directions toward and away from the first polishing surface.

To improve precision in collation processes or create a database of collation images by registering at least a part of captured images not matching a previously registered face image, as a collation face image, a face collation apparatus includes an image acquirer that acquires captured face images captured by a capturing device, a registered-person image storage that stores registered-person images that are previously registered face images, an image collator that collates the captured images with the registered-person images, an unregistered-person image storage that stores the captured images that do not match the registered-person images, an image output that outputs at least one of the unregistered-person images stored in the unregistered-person image storage to a display device, and an image register, selected to be registered by a user, that registers the unregistered-person image, among the unregistered-person images output to the display device, as a registered-person image in the registered-person image storage.

The invention discloses a casting after-finishing assembly line and a finishing method thereof. The casting after-finishing assembly line comprises a feeding mechanism, a finishing mechanism, a conveying mechanism for distributing castings to the finishing mechanism, and a control mechanism. The finishing mechanism comprises a thin casting finishing module, a circular casting finishing module anda finishing module for other castings. During finishing, the castings are conveyed into the conveying mechanism through the feeding mechanism, the castings are distributed to one of the thin casting finishing module, the circular casting finishing module and the finishing module for other castings through the conveying mechanism for finishing. According to the casting after-finishing assembly line, the castings of different types can be subjected to finishing, and the universality of the equipment is improved; the whole system is controlled through a control system, and therefore online automatic finishing of the castings is achieved.
