Definitions
- the invention relates to a process for the preparation a part of an electromagnet with a center leg and two outer pole legs, each having a pole face and have a facing away from this back.
- the pole faces of the Iron parts i. Anchor and yoke, ground as smooth as possible.
- the flatness of the backrest is the Loops imaged on the support surface. Due to machine and part tolerances, this image is concave or convex. In the concave image are the inner leg sides not required, i. It creates an air gap, the weakens the tributary in the magnet system. This leads to a Reduction of holding power and increase in the tendency to hum the magnet systems.
- a method according to the preamble of claim 1 is known from JP 05 06 2852 A.
- the invention is based on the object, a manufacturing method of the type mentioned above to improve that in a simple way a defined form of the through the Pol vom formed contact surface is achieved.
- an iron part 1 of an electromagnet e.g. one Anchor or yoke, represented by a middle leg 2 and has two outer pole leg 3. These each have one Pol requirements 4.
- the facing away from the back 5 is free form and has a rectangular surface geometry.
- the iron part 1 is shown in the state in which it by a magnetic clamping device, not shown here in the direction of the back 5 is elastically braced.
- the pole faces 4 are ground straight, as shown in FIG.
- the iron part 1 After removal from the jig, the iron part 1 springs back to its original shape according to FIG 3, so that again the rectangular surface geometry of the back of FIG. 1 and at the same time indicated by the pole faces 4 a dashed line concave bearing surface 6 results.
- the embodiment according to FIG 4, 5 and 6 differs Compared to the above described only in that the back 5 here with a different surface geometry with has a round shape. For the rest, however, by the mentioned manufacturing steps also the result of a reached convex bearing surface.
