In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1, as shown in fig. 1, a novel dc electromagnetic mechanism includes: a housing 1 and a return device; a sleeve 2 is arranged in the shell 1; the return means is arranged at the bottom of the sleeve 2:
an armature 3 and an iron core 4 are arranged in the sleeve 2, and a coil 5 is arranged on the outer side wall;
the armature 3 is positioned below the iron core 4;
the return means are connected to the armature 3.
It should be noted that if the magnetic field moves relative to the conductor, the electromagnetic drive will generate an induced current in the conductor, and the induced current will make the conductor subject to an ampere force, which will make the conductor move, and this action is the electromagnetic drive.
In this way, when a current is applied to the coil 5, an electromagnetic attraction force is generated between the armature 3 and the core 4, and the core 4 is fixedly connected, so that the armature 3 moves toward the core 4, and the member connected to the armature 3 moves.
In electromagnetic mechanisms, the armature is typically made of soft magnetic materials, such as pure iron, cast iron, silicon steel, permalloy, and the like; the iron core is generally made of silicon steel sheet, the silicon steel is silicon-containing steel, the silicon content of the silicon-containing steel is 0.8-4.8%, and the iron core of the transformer is made of the silicon steel, because the silicon steel is a magnetic substance with strong magnetic conductivity, in an electrified coil, the silicon steel can generate larger magnetic induction intensity, and therefore the armature can be attracted more conveniently.
In addition, the return device is used for pulling the armature 3 back to the initial position to prepare for the next movement; the sleeve 2 is used for mounting the armature 3 and the iron core 4 and controlling the armature 3 to do linear motion.
In an embodiment of the present invention, the iron core 4 is connected to the sleeve 2 through a bolt 6; thus, it is more convenient to install and remove the iron core 4.
In one embodiment of the utility model, the inner wall of the sleeve 2 is provided with the ball 7, and both side surfaces of the armature 3 are in sliding contact with the ball 7; in this way, the friction between the armature 3 and the sleeve 2 during movement is reduced, on the one hand, the movement speed of the armature 3 is increased, and on the other hand, the friction loss of the armature 3 is reduced.
In one embodiment of the utility model, the bottom of the armature 3 is provided with a pull rod 8; by connecting the pull rod 8 to the member, the movement of the connected member can be controlled by controlling the movement of the armature 3.

a moving block 11 is arranged on the connecting rod 9, and the return device is hinged between the moving block 11 and the armature 3;
when the connecting rod 9 acts, the moving block 11 moves on the connecting rod 9, so that the armature 3 is driven to move up and down.
It should be noted that, for example, when the connecting rod 9 is a threaded rod, the moving block 11 is a sliding sleeve, and the sliding sleeve is in threaded connection with the threaded rod 9, so that when the coil 5 is used for too long time or damaged by various factors, the magnetic attraction between the iron core 4 and the armature 3 is weakened after the coil 5 is electrified, and at this time, the sliding sleeve can be made to approach the fixing member 10 by adjusting the threaded rod, so as to adjust the distance between the armature 3 and the iron core 4, and further make the armature 3 approach the iron core 4 more conveniently;
in addition, when the armature 3 moves towards the iron core 4 to complete the relevant operation, the armature 3 needs to return to the original position to prepare for the next movement, and at the moment, the armature 3 can be pulled back to the original position through the return device; for example, the moving device may be a hollow tube, a pull rod is disposed in the hollow tube, and the connecting rod and the hollow tube are provided with an elastic member, the pull rod is hinged with the armature, the hollow tube is hinged with the sliding sleeve, and the armature 3 can be returned to the original position by the acting force of the elastic member after the armature 3 moves towards the iron core 4 to complete the relevant operation.
