Definitions

  • the invention relates to a lifting magnet according to the preamble of claim 1 and a manufacturing method of such a magnet according to claim 11.
  • Solenoids are actuating magnets with which switching or control functions are made.
  • the anchor as an actuator can take any intermediate positions and must hold them even with opposing forces.
  • lifting magnets work either pushing or pulling.
  • the return to the currentless stroke output position usually takes place by a force acting against the magnetic force compression spring.
  • a widely used construction form of lifting magnets is the pot magnet.
  • This magnetic construction consists of at least three magnetic components: a cylindrical, hollow magnetic body, which is constructed of pole, yoke and a non-magnetic, flux-carrying housing, is embedded therein an axially extending cylindrical coil body with current-carrying coil, and the cylindrical armature, at its end In the stroke direction, a guide rod is arranged as an actuating element and carries out the lifting movements within the magnet body ( DE 44 39 422 A1 ).
  • the pole of the magnetic body is divided into an axial cylindrical region and a radial region for manufacturing reasons. Both areas are either a component ( DE 44 38 158 A1 ), or could for manufacturing reasons also consist of two different components.
  • the axial region of the pole which is referred to below as a cone, is essentially a cylindrical body, which is arranged in the opening of the magnetic body. It has, at its end facing the armature, a contraction sloping in the direction of the armature, which are designed in such a way that the lifting force generated by magnetic force is proportional to the applied current in the coil ( DE 44 39 422 A1 ).
  • the cylindrical components In its interior, the cylindrical components on a central through hole, which is penetrated by the actuating rod of the armature.
  • the radial region of the pole is disk-shaped and provided with a central opening whose axial region is connected to the outer diameter of the cone.
  • the radially extending portion of this component has a planar bearing surface which is connected to the end of the bobbin and the housing. Due to the disk-shaped arrangement, this component is referred to below as a cone disk.
  • the storage and guidance of the cylindrical armature in the opening of the magnetic body takes place in a bearing sleeve.
  • the axially extending portion of the sleeve engages over the cone at its open end.
  • the bearing sleeve can be configured as a pot closed on one side or as a tube.
  • the yoke of the magnetic body is arranged on the opposite end of the cone of the bobbin. Similar to the conical disk, this disk-shaped component has a central opening which is partially or completely penetrated by the end of the bearing sleeve.
  • the component referred to below as a yoke disc has a radial recess or a passage and is in contact with its axial inner region with the bearing sleeve. By contrast, the outer axial region is firmly connected to the flow-guiding housing at this point.
  • the individual components of the magnet such as the yoke disc, the housing and the cone disc are individually connected together in a special joining and pressing process and formed into a hollow body according to the prior art.
  • the individual components are plugged together and connected at the joints with each other by caulking.
  • a large game is required, which leads to large concentricity deviations during caulking ( DE 102 38 840 A1 ).
  • a manufacturing method for a solenoid is known in which individual components of the magnet are summarized prior to final assembly in advance to form several modules. The individual assemblies are then assembled into a finished magnet.
  • the armature is first equipped with the actuating rod and inserted into the guide sleeve or in the guide tube in.
  • the guide diameter of the armature and the sleeve or of the tube are manufactured in one clamping in order to keep concentricity deviations minimal.
  • the cylindrical cone is inserted into the bearing / guide sleeve and firmly connected at its optimum position, taking into account the stroke of the armature with the wall of the sleeve or the tube in this position.
  • the cartridge-shaped assembly thus formed is then subsequently installed in the hollow body, which constitutes a further assembly formed from the housing with inserted coil, the yoke disc and the cone disc.
  • the object is achieved in connection with the preamble device by the characterizing features of claim 1 and manufacture by the characterizing features of claim 11.
  • the improvement of the hysteresis is achieved by centering the magnetic flux in the flux-guiding parts of the magnetic body, whereby lateral forces are reduced. It will reach a uniform magnetic air gap around the anchor.
  • the guide body (sleeve or tube), stored after installation centrally to the yoke disc and the pole. The individual components can thus be manufactured and assembled with less play.
  • the manufacturing method for the magnet is based on the modular system known per se, which consists in first of several components of the magnetic body of individual components form, which can also be used for other applications, and assemble the magnets from given assemblies.
  • the yoke disc is placed only loosely during manufacture on the flat surface of the housing end and aligned in this position on the bearing sleeve. Subsequently, the fixation takes place axially on the plane surface of the housing end. As a result, no transverse forces at the connection point that cause the joining process occur at this point.
  • the yoke disc can thus be placed in the manufacturing process with very close clearance on the guide sleeve and will be connected in this position with the flat surface of the housing.
  • the yoke disc is not pressed into the housing in the production, but only loosely placed on this and the flat surface connected to the housing end.
  • the guide sleeve or the guide tube is installed stress-free and centered with the yoke disc.
  • the preferred type of joint for connecting the yoke disc to the housing is welding, which offers advantages over caulking of the components.
  • the cone disk after the alignment of the yoke disk on the bearing sleeve or on the bearing tube, the cone disk can also be positively and / or positively connected to one another in the same manner, whereby welding is also preferred here as the type of joint.
  • the non-positive and / or positive joining of the two modules is advantageously carried out by pressing in, caulking or welding.
  • the bearing sleeve is positively and / or positively connected only with the cone, which is positively and / or positively connected to the cone disk. This compound is preferably welded.
  • a radial seal is provided between the bearing tube and the bearing sleeve and the cone, which is designed in particular as O-rings. This is the case when the magnet space is tightly filled with oil or gasoline or other medium.
  • the housing is advantageously non-positively and / or positively connected with the cone disk.
  • This compound which is usually caulked or welded, is particularly advantageous in the design of the magnet when conical disk and cone, so the entire pole, form a single component.
  • this component projects radially outward at the open end of the cartridge.
  • the pole comprises two separate components - the cylindrical cone and the radially mounted on the cone pole disk -, the junction cone / conical disk is non-positively and / or positively connect with each other.
  • the cylindrical cone advantageously has at its end facing the conical disk a radially extending annular elevation, which serves as an axial stop in the introduction of the cone disk on the cone.
  • the flux-guiding housing is advantageously designed as a tubular jacket made of a stampable and bendable material.
  • the tubular material is rolled around the interior of the magnet.
  • the "rolled" jacket and the use of a thin-walled tube is possible as a housing in which the necessary openings for the connecting flange and other components are punched in advance.
  • the coil has cams on its plane surface in the axial direction. These press during assembly in the bearing surface of the yoke disc.
  • the coil is axially fixed in the "cage" of the housing through the cone disc and yoke disc.
  • anchor and the bearing sleeve or the bearing tube form a first assembly, which are joined together to form a cartridge-shaped body.
  • the housing with the coil, the conical disk and the yoke disk are combined to form a second assembly and assembled into a cylindrical, hollow-shaped structure.
  • the cartridge-shaped structure is then introduced into the coaxial opening of the hollow body and both structures are non-positively and / or positively connected to each other.
  • the yoke plate is connected to the housing end prior to insertion of the cartridge into the hollow body.
  • the cartridge is only radially centered after insertion into the hollow body in the yoke disc.

  • the axial guidance takes place at the opposite end by the stop of the cone with the conical disk.
  • the stop on the axial end of the cone is pressed into the cone disk.
