Definitions
- the invention relates to a method for the production of interconnected laminations consisting of packages for magnetic cores, so-called laminated cores.
- Laminations of this type are used, inter alia, in various electromagnetic apparatus, such.
- reactors transformers, actuators, actuators such.
- laminated cores in magnetic circuits has been state of the art for many years and serves to reduce eddy currents, the z. B. in transformers to increase the losses or contribute to solenoid valves to extend the switching times.
- ring-belt cores are used, but they have the disadvantage that the coils needed for the control have to be pushed before closing the magnetic circuit.
- laminated cores By specifying a rectangular iron cross-section in laminated cores, the use of laminated cores in various cases could not be optimized so far. In many applications, it is desirable to keep the recesses for the laminated cores to be inserted round or oval.
- JP-A-09 213 543 and EP-A-0 738 831 Methods are known in which sheet packages with round or oval iron cross section become available, but due to the assembly of the magnetic core of two or more packages of previously assembled lamellae, these methods are cumbersome.
- the device according to the invention for carrying out the method is characterized by the features of claim 10.
- the cutting punches are moved by motor to the width of the next sheet.
- This next lamella 2 has approximately 50% of the width of the coil core.
- this lamella 2 are introduced in the same follower tool on one side with depressions and on the other side with the wells B matching and opposite them warts C. As a result, then the slats are knotted 3 to 11 with increasing width analog.
- the lateral cutting punches are then brought together successively again, so that the package shown in FIG. 3 and FIG. 4 can be removed as a finished part from the progressive die tool.
- cylindrical coil cores were made of 0.5 mm thick grain-oriented iron silicon, which varied in diameter from 5 mm to 20 mm.
- FIG. 5 shows an EK core 20 with a rectangular iron cross-section according to the prior art.
- EK cores are used in actuators for diesel injectors.
- the task here was to produce an EK core, which can be screwed into a limited volume of construction and can achieve a high level of force.
- the EK core 20 shown in FIG. 5 has only insufficient results, since the area utilization of the round outer contour 21 for the iron cross section is only 31%.
- the round EK core 30 shown in FIG. 6 was adapted to the round outer contour 31 using the method according to the invention.
- the design of the follow-on composite tool was carried out as for the production of the cylindrical coil cores shown in Figures 3 and 4 by moving the cutting punch.
- the round EK core 30 of the following invention shown in FIG. 6 has a significantly higher area utilization in comparison to the EK core 20 from FIG. Thereby a 20% higher area utilization was achieved.
- the laminations were again made of iron silicon and compared with prior art laminations.
- an increase in the magnetic circuit force level of 20% was achieved.
- FIG. 7 shows an EK core 40 according to the present invention with a breakthrough on the middle leg, like the one shown in FIG DE-U 2951 4508 can be seen.
- a recess 43 is provided to the center, so that in the application a central guide for a valve rod (not shown) is made possible.
- the force level could be increased by 19% compared to a comparable laminated core with a rectangular iron cross section.
- the EK core 40 shown again consists of grain-oriented iron silicon.
- the limitation on the utilization of the circular area is determined by the width of the outer sheet metal layers.
- a further optimization according to the invention can take place in that the required for the production of cores inner cutting punch the follow-on composite tool are moved by a motor. As a result, the center leg of the laminated core is rounded and thus created sufficient space for the outer layers so that a punching technical link in the tool is still possible.
- FIG. 8 shows a laminated core 50 adapted to the round shape, in which a 44% larger iron cross-sectional area is achieved in comparison with the laminated core from FIG. 6 with a rectangular iron cross-section.
