    • An apparatus for retaining a package of laminations of an electromagnetic core in a device (3) for the production thereof that is mounted into a panel (1) arranged at a distance from a yoke (2) of said device (3) for the production of individual laminations (4) and mutual joining of same into a package (5), wherein it comprises peripheral units like an aggregate for pressurized hydraulic oil, sensors, control unit and ejector. The apparatus of the invention is formed in a way that within said panel (1) a cylinder (7) is arranged co-axially with a sleeve (6) within said yoke (2), said cylinder (7) housing a hydraulic piston (8) with a piston rod (9) with a coaxial drilled hole (12), wherein on the top of said piston (8) adjacent to said sleeve (6) there is a pivotally mounted panel (10) that is simultaneously supported on said piston (8) by a spring (11) and said piston rod (9) is further led within said cylinder (7) at a distance by means of three mutually distant gaskets (14) in order to create two spaces (15) and (16) between said piston rod (9) and said cylinder (7) in that a central section (9a) of said piston rod (9) is thinner and that both spaces (15) and (16) are provided with hydraulic connections (17) and (18) for an alternate supply of pressurized oil into one or another space (15) and (16).
    • 一种用于将电磁芯的叠片保持在用于制造其的装置(3)中的装置,其被安装在布置成距所述装置(3)的轭(2)一定距离的面板(1)中用于生产 的单独叠片(4)并将其相互连接到包装(5)中,其中它包括外围单元,例如用于加压液压油的集料,传感器,控制单元和喷射器。 本发明的装置形成为在所述面板(1)内形成一个圆柱体(7)与所述磁轭(2)内的套管(6)同轴设置,所述气缸(7)容纳液压活塞 8)具有同轴钻孔(12)的活塞杆(9),其中在所述活塞(8)的与所述套筒(6)相邻的顶部上具有枢转安装的面板(10),其同时支撑在所述 活塞(8)通过弹簧(11)和所述活塞杆(9)进一步通过三个彼此间隔的垫圈(14)在所述气缸(7)内一定距离地引导,以便产生两个空间(15)和( 在所述活塞杆(9)和所述气缸(7)之间,所述活塞杆(9)的中心部分(9a)更薄,并且两个空间(15)和(16)都设有液压连接件 )和(18)用于将压力油替代供应到一个或另一个空间(15)和(16)中。
