- This sheet blank 6 is made from a larger sheet uniform thickness according to the required dimensions e.g. punched out. Then the sheet metal blank 6 is under Rolled a mandrel into the desired shape or bent so that it takes on a shape as shown in Figure 5 is shown. With the arrows 61 is the rolling movement indicated.
- Each individual sheet blank 6 for the production of a Magnetic jacket 60 is characterized by a specific Contouring out, with a division into three areas makes sense.
- a central area 63 ultimately a surrounding the magnetic coil 1 in the circumferential direction
- Sheath area 630 of the magnetic jacket 60 forms, close in the axial direction according to the installation in the valve on a first line of extension an upper and a lower edge area 64 and 65.
- the two edge areas 64 and 65 ultimately form attachment regions 640 and 650 of the magnetic jacket 60, with which an attachment to the core 2nd and is made possible on the valve seat support 10.
- the edge regions 64 and 65 are characterized in that they are segmented, meaning that of an upper one and lower boundary edge 66 and 67 starting from each several recesses 68 and 69 towards the middle Area 63 are introduced, the segments of the form respective edge region 64, 65.
- the recesses 68, 69 extend from the boundary edge 66, 67 for example, first with parallel side edges that face each other later converges to a pointed recess end 70, 71 stretch directionally.
- both edge areas 64, 65 are e.g. three recesses 68, 69 at the same distance from each other introduced so that the recesses 68 of the upper Edge area 64 exactly opposite the recesses 69 of the lower edge region 65 are formed.
- the two edge regions 64, 65 differ. While in the lower edge area 65 to the two outer Recesses 69 each again a complete segment connects and the lateral boundary edges 72 and 73 therefore have the contour of a half recess 69, are lateral boundary edges 72, 73 of the upper edge area 64 less than a segment width away from the two outer recesses 68 provided and also rectangular to the upper boundary edge 66. Compared to the lateral boundary edges 72, 73 of the edge regions 64, 65 are the lateral boundary edges 74 and 75 of the middle area 63 deepened, which after rolling the Sheet metal blank 6, the jacket area 630 of the magnetic jacket 60 has a window 80 ( Figure 5) through which Boundary edges 74, 75 is limited.
- the two Edge areas 64, 65 in perpendicular to the first Extension line extending second extension lines over the middle area 63 over.
- the recess ends 70, 71 of the recesses 68, 69 are approximately at the level of Transition shoulders of the lateral boundary edges 72, 73 to the boundary edges 74, 75 of the central region 63, since the later magnetic jacket 60 also in these areas Shoulders 78, 79 ( Figure 5) should have.
- the method of manufacturing the magnetic shell 60 is subdivided after the provision of the sheet metal blank 6 with the required contour in two essential steps.
- a first process step the entire sheet blank 6 e.g. rolled by means of a mandrel or bent until the two side Boundary edges 72, 73 of the lower edge region 65 face directly.
- a second Process step will be the upper and the lower Edge area 64, 65 e.g. with a clasp-like tool by deformation to a smaller outside diameter brought, the recesses 68, 69 to a minimum Width can be reduced so that the push the intervening segments closely together.
- the resulting fastening areas 640, 650 act Collet-like and can be easily opened during assembly become. Since the attachment areas 640, 650 under Are bias, the position of the magnetic jacket 60 at the assembly of the valve on the core 2 and the Valve seat bracket 10 already well fixed. As before mentioned, two shoulders 78, 79 ( Figure 5) arise as Transitional areas of the jacket area 630 to the two Attachment areas 640 and 650, the smaller one Have outer diameter than the jacket area 630. Die Recess ends 70, 71 are in the area of Shoulders 78, 79.
- Figure 3 is a plan view of the sheet metal blank 6 magnetic sheath produced according to FIG. 2 60 shown, while Figure 4 is a bottom view of this Magnetic jacket 60 shows.
- Figure 5 is in turn Sectional view of the magnetic jacket 60 along the lines V-V in FIGS. 4 and 5.
- FIG. 3 shows that the lateral boundary edges 72, 73 of the upper Edge area 64 are spaced apart so that on simple way coil pins of the magnet coil 1 through this existing space 81 axially from the magnetic jacket 60 can be performed.
- the sectional view according to FIG. 5 indicates that the Jacket area 630 does not completely revolve, but through the window 80 is interrupted.
- the size of the window 80 depends on the depth of the boundary edges 74, 75 of the middle area 63 on sheet metal blank 6.
- the window 80 can e.g. take a size of about 120 °, making a third of the circumference of the jacket region 630 is open. Because of this Window 80, the magnetic coil 1 is inserted radially, the is indicated schematically in Figure 5.
- the magnetic coil 1 can be inserted through the window 80 Jacket area 630 also in a simple manner be slightly bent.
- the window 80 can also from seen in the circumferential direction 120 ° larger or be made smaller.
- Figure 6 shows a second embodiment of a Sheet metal blank 6 for a magnetic jacket 60, which differs from that Sheet metal blank 6 according to Figure 2 differs in that both edge areas 64, 65 identical, but mirrored around the central area 63.
- the upper edge region 64 is thus also an example formed that the two outer recesses 68 up to the lateral boundary edge 72, 73 each connects a complete segment. Because in the rolled State of the magnetic jacket 60 thus no more space 81 is present, the coil pins of the magnetic coil 1 in this Fall led radially sideways out of the window 80.
- the invention is in no way related to fuel injectors limited, but generally affects everyone Electromagnetically operated valves of different types Application areas.
