Definitions

  • the invention relates to an anchor rod assembly for an electromagnet.
  • the invention further relates to a method for producing such an anchor rod assembly and to an electromagnet with such an anchor rod assembly.
  • Known anchor rod assemblies have a spring element, which can serve to release or close outlet openings of a valve chamber of an electromagnet or of an electromagnetically actuated solenoid valve.
  • the spring element is fixed by means of a fastening nut on the anchor rod, wherein the fastening nut on the anchor rod is screwed on (such as in US2111232 ). This has proven to be cumbersome and unreliable in practice.
  • the invention relates to an anchor rod assembly of an electromagnet, consisting of an anchor rod which carries a collar on which abuts a spring element and the spring element is held by a Verstemmring, which is at least partially positively connected to the anchor rod.
  • the version with the Verstemmring allows a simpler compared to the version with a mounting nut process management and better durability.
  • the spring element can be held axially between the collar and the Verstemmring.
  • the anchor rod and / or the Verstemmring on at least one receiving space, which receives a Verstemmwulst the Verstemmrings and / or the anchor rod to form the positive connection.
  • This allows a reliable positive connection by caulking.
  • a groove for. B. a circumferential groove provided on the anchor rod. This corresponds to a simple and reliable execution.
  • a knurl for fixing the spring element against rotation on the anchor rod is applied adjacent to the collar.
  • the positive connection can be increased to the spring element, so that a torque is transferable and an anti-rotation is achieved.
  • the spring element is a meander spring. This has proven to be advantageous for typical applications. It allows the application of a defined pressure to close outlets.
  • the spring element is designed as a spring-sealing element and has a sealing area.
  • a sealing area can preferably be used for closing outlet openings. He is further preferred pressed by the already mentioned above meandering spring in the closed state against the outlet openings to close them with a defined force.
  • the spring element between the Verstemmring and the collar is clamped axially.
  • a game of the spring element which could lead to wear over time, can be effectively avoided.
  • the federal government is integrally formed by means of machining shaping on the anchor rod. This allows a particularly reliable connection between the anchor rod and collar.
  • the collar is initially formed as a separate item, which with the anchor rod is positively connected or materially connected. This allows a separate production of anchor rod and collar, which allows, for example, the use of different materials or special shaping methods.
  • the disclosure of this application includes all amounts of intervals in which one of these values is used as the lower limit and another of these values as the upper limit.
  • the invention further relates to a method for producing an anchor rod assembly of an electromagnet, in particular an anchor rod assembly according to the invention, wherein a spring element and a Verstemmring be pushed onto the anchor rod on an anchor rod, which carries a federal government, and a caulking takes place in such a way that the Verstemmring least partially positively connected to the anchor rod and the spring element is pressed against the federal government.
  • the inventive method enables a particularly simple production of an anchor rod assembly, which has particularly advantageous properties, for example in terms of strength.
  • an anchor rod assembly according to the invention can thus be produced with preference.
  • the anchor rod assembly can be used on all the above-described embodiments and variants. Illustrated benefits apply accordingly.
  • the sliding of the spring element or the Verstemmrings takes place axially or radially with respect to the longitudinal axis of the anchor rod.
  • the invention further relates to an electromagnet or an electromagnetically designed solenoid valve which has a yoke with a continuous anchor bore, wherein the anchor bore opens into an anchor chamber receiving the armature or an armature receiving armature chamber, which at least partially acted upon by an electric current Winding is surrounded, wherein the anchor bore receives the anchor rod of an anchor rod assembly according to the invention, wherein the collar is arranged on the side facing away from the armature chamber of the anchor hole, and wherein the anchor rod is connected to the armature.
  • the advantages of the armature assembly according to the invention described above for an electromagnet or a solenoid valve can be utilized. It can be used on all described versions and variants of the anchor assembly. Illustrated benefits apply accordingly.
  • the armature assembly can be produced by means of a method according to the invention.
  • a recess is provided on the yoke on the side opposite the armature chamber side of the anchor hole, in which the federal government is able to submerge.
  • This can be achieved in an advantageous manner, a hydraulic damping.
  • the collar when striking the yoke, the collar may abut against a film extending over the yoke from a medium to be controlled, for example a hydraulic oil. Thus, the impact energy can be mitigated.
  • the yoke has at least one outlet opening
  • the spring element is designed as a sealing-spring element and performs the movement of the armature via the anchor rod assembly to an opening or closing movement of the sealing-spring element at the outlet opening.
  • FIG. 1 shows an electromagnet 10 according to an embodiment of the invention.
  • the electromagnet 10 is part of a solenoid valve 100.
  • the electromagnet 10 has a yoke 110 in or on which the other components described below are arranged.
  • an anchor hole 111 and an armature chamber 145 are formed in the yoke 110.
  • the armature chamber 145 is closed at the top by a magnetic core 120.
  • an armature 140 is arranged in the armature chamber 145, which is connected by caulking with an anchor rod 150.
  • the anchor rod 150 extends downwardly through the anchor bore 111.
  • a compression spring 125 which pushes the armature 140 away from the magnetic core 120.
  • a winding 130 is arranged, which is surrounded by a coil core 135.
  • a direct current By applying a direct current through the winding 130, a magnetic force can be exerted on the armature 140, which is opposite to the force exerted by the compression spring 125 force. This allows the armature 140 to be moved up and down together with the armature rod 150 by turning on and off the direct current through the coil 130.
  • the anchor rod 150 Adjacent to the armature 140 opposite end of the anchor rod 150, the anchor rod 150 has a collar 152 which projects radially outward. The collar 152 is contained in a recess 190 formed in the yoke 110.
  • the armature 140, the anchor rod 150 and the collar 152 are arranged in a common upper position. This position is achieved against the force of the compression spring 125 by means of the magnetic force imparted by the winding 130. It should be understood that when the DC current flowing through the winding 130 is shut off, the armature 140, armature rod 150, and collar 152 move together to move downwardly to a common lower position.
  • a Verstemmring 160 is arranged, which is caulked with the anchor rod 150.
  • the caulking ring 160 is fixedly connected to the anchor rod 150. Details will be explained below.
  • the spring element 180 is in each case directly contacted by the collar 152 and the Verstemmring 160, so that it is firmly clamped between the collar 152 and the Verstemmring 160. It thus moves with the movement described above between the upper position and lower position. In other words, the spring element 180 can also be moved up and down in a controlled manner by means of the winding 130.
  • valve chamber 116 has two outlet openings 114, at which the lines 112 begin.
  • the valve chamber 116 further includes an inlet 118 through which a medium to be controlled may enter the valve chamber 116.
  • the spring element 180 on an outer sealing portion 200, which closes the two outlet openings 114 in the illustrated upper state.
  • a medium entering through the inlet 118 can not enter the conduits 112.
  • the lower position (not shown) is assumed by the composite of armature 140, anchor rod 150, collar 152, caulking ring 160 and spring element 180 with sealing region 200, the outlet openings 114 are released from the sealing region 200.
  • the sealing area 200 lies in the in FIG. 1 shown with a certain bias to close at the outlet openings 114 at. The bias is mediated by the spring element 180.
  • FIG. 2 shows an intermediate state in a method for producing an assembly according to the invention.
  • the spring element 180 is already attached to the anchor rod 150, and Although below the collar 152. It can also be seen that in the anchor rod 150 below the collar 152 and below the spring member 180, a groove 158 (or receiving space 158 or circumferential groove 158) is formed.
  • the anchor rod 150 in the area where the spring element 180 is mounted, further a knurl 164 on. This serves to further improve the contact between the spring element 180 and the anchor rod 150. In particular, torques between the anchor rod 150 and the spring element 180 can be transmitted in this way.
  • FIG. 3 shows a finished anchor rod assembly 1, which consists of the in FIG. 2 shown intermediate state.
  • the Verstemmring 160 was attached from below onto the anchor rod 150 and caulked with the anchor rod 150.
  • a projection formed in the caulking ring 160 engages, which is described below with reference to FIG FIG. 4b will be described, into the groove 158 (or receiving space 158 or circumferential groove 158) of the anchor rod 150 a.
  • the spring element 180 is axially clamped between the collar 152 and the Verstemmring 160 held.
  • FIG. 4a shows the anchor rod assembly 1 of FIG. 3 in conjunction with the yoke 110.
  • the anchor rod 150 is already received in the anchor rod bore 111 of the yoke 110. This corresponds to the arrangement of the anchor rod assembly 1 in the yoke 110, as already in FIG. 1 will be shown.
  • Verstemmring 160 From the bottom adjoins the Verstemmring 160 a Verstemmst Zi 170. This is used during manufacture to caulk the caulking ring 160 with the anchor rod 150. It is understood the caulking punch 170 is only needed during manufacture and typically will no longer rest on the anchor rod 150 in a finished electromagnet 10.
  • FIG. 4b shows the range of FIG. 4a which is in FIG. 4a marked by a circle, enlarged. It can be seen that a Verstemmwulst 162 is formed on the Verstemmring 160, which engages in the groove 158 (or receiving space 158 or circumferential groove 158) of the anchor rod 150. As a result, a positive connection between the Verstemmring 160 and the anchor rod 150 is formed. This remains in particular even when the caulking 170 is removed from the anchor rod 150 again.
