Embodiment Construction

[0024] See Figure 1-3 , the present invention relates to a panel assembly, hereinafter referred to as a panel pack, comprising magnetic panels 1, 2, 3, which are processed by any means such as welding, riveting, clipping or interlocking (mutual engagement of elements, such as tenon and openings, stamped in corresponding relation in adjacent plates), keyed, etc. and integral screw arrangement for assembly. By screw means is meant any part adapted to co-operate with another part in a screwed manner. These screw arrangements secure the tablet pack to a frame or another device, or secure a component, case, or another device to the tablet pack.

[0025] Such packs are manufactured from a sheet of metal sheet which is cut into flat sheets to form flat packs. The slabs are cut and formed by means of a press provided with tools including punches which are started and stopped to form the outer contour of each slab and the appropriate openings which form the wells or openings in the ...

Abstract

The assembly has a fixing unit for fixing an external element, and a set of magnetic plates (1-3), where some of the plates have T shaped cut-outs (12, 13) to form a housing receiving an insert e.g. nut (10). The insert is provided with a fixing unit i.e. screwing unit, and includes a fixing axis i.e. screwing axis. The housing is arranged to retain the insert in the assembly. A wall of the housing is in contact with an exterior surface of the insert to immobilize the insert in rotation about the screwing axis and to retain the insert along the screwing axis. An independent claim is also included for a method for manufacturing a set of magnetic plates for electromagnetic machines.

Description

technical field [0001] The invention relates to a panel assembly provided with fixing means and to a method of manufacturing such a panel assembly. Background technique [0002] Such flat packs (or flat packs) find particular application in the production of armatures for electromagnetic machines, such as alternator or electric motor stators or rotors, transformer armatures, and the like. [0003] Such bales are typically manufactured from a sheet of metal sheet that is cut into flat sheets to form flat bales. The slab is cut by a tool including a punch that is activated or stopped to create different openings depending on the slab. The slabs cut in this way are stacked on top of each other and secured to each other by welding, riveting, clipping or interlocking (mutual engagement of corresponding punched elements in adjacent slabs), keying or the like. [0004] The following are several possible embodiments of the screw arrangement. [0005] In a first embodiment, the th...
