Abstract
The utility model discloses a novel electromagnet which is characterized by comprising a shell and an armature. The armature is provided with a first free end and a second free end, both the first free end and the second free end extend out of the shell, the second free end is connected with a workpiece, and the first end is a stressed end. The novel electromagnet has the advantages that the armature is provided with the first free end and the second free end which penetrate through the shell, the second free end is connected with the workpiece, and the first end pulls downwardly to drive the workpiece and the electromagnet to move, so that the gravitational force, which is resistance for preventing the workpiece from moving, of the electromagnet is turned into power for pulling the workpiece to move, attractive force of the electromagnet is sufficiently utilized, and force acting on the workpiece is the composition of the attractive force and the gravitational force of the electromagnet; energy consumption is saved, and the work efficiency is improved; and the novel electromagnet is obvious in energy-saving effect when applied to a reverse sewing device of a sewing machine.
Description
Technical field
The utility model relates to a kind of new electromagnet.
Background technology
Electromagnet is to be wound around in the outside of iron core the coil that is complementary with its power, and alive coil has magnetic as magnet.Electromagnet is widely used in electromagnetic relay, industrial automatic control, office automation, automation control appliance, package packing machine, medicine equipment, food machinery, textile machine etc.Present a kind of electromagnet that is used in Sewing machines reverse stitching comprises housing, coil and armature, and armature and coil are arranged in housing, and coil is set on armature.After coil electricity, armature can move along its axis direction.This kind electromagnet is in when work, armature one end fixation workpiece, and after coil electricity, armature is magnetized and moves, and the ejection workpiece moves upward.This kind electromagnet is when making progress the ejection workpiece motion s, and the power that acts on workpiece is the gravity that active force deducts electromagnet.The suction that this kind electromagnet produces partly is used for overcoming the gravity of electromagnet self, causes the waste of energy consumption.
The utility model content
The purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of and can take full advantage of suction, thereby saves the new electromagnet of energy consumption.
For realizing above purpose, the utility model is achieved through the following technical solutions:
A kind of new electromagnet comprises housing and armature, and described armature has the first free end and the second free end, and described the first free end and the second free end all stretch out in outside described housing, and described the second free end is connected with workpiece, and described the first free end is the force side.
Preferably, described push rod one end connects workpiece, and the other end is the force side.
Preferably, also comprise two end cap, described two end cap covers respectively described housing two ends.
Preferably, also comprise coil, described coil is located in described housing and is set on described armature.
New electromagnet of the present utility model is set to run through the first free end and second free end of housing by armature, the second free end connects workpiece, and the first free end pulls down start building part and electromagnet motion.The gravity that makes electromagnet self becomes by the resistance that hinders workpiece motion s the power that pulls workpiece motion s, not only takes full advantage of the attraction of electromagnet, and to make the power that acts on workpiece be attractive force of electro-magnet and electromagnet gravity sum.Save energy consumption, improved operating efficiency.When new electromagnet of the present utility model was applied in Sewing machines reverse stitching, energy-saving effect was more obvious.
Description of drawings
Fig. 1 is the three-dimensional exploded view of new electromagnet of the present utility model.
Fig. 2 is the cutaway view of a kind of operating state (during outage) of new electromagnet shown in Figure 1.
Fig. 3 is the cutaway view of the another kind of operating state (during energising) of new electromagnet shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1 to Figure 3: new electromagnet comprises housing 1, coil 2, armature 3 and two end cap 4.Coil 2 and armature 3 all are installed in housing 1.Coil 2 is sleeved on armature 3.Two end cap 4 is covered on respectively housing 1 two ends.Armature 3 has the first free end 31 and the second free end 32.The first free end 31 and the second free end 32 all stretch out in outside end cap 4.Fix a push rod 5 on armature 3.Push rod 5 stretches out in outside end cap 4.Push rod 5 one ends 52 connect workpiece, and the other end 51 is the force side.
As shown in Figure 2, during outage, an end 51 of push rod 5 is positioned at housing 1.The other end 52 of push rod 5 stretches out in the outer certain distance of end cap 4.
As shown in Figure 3, during energising, make armature 3 be magnetized after coil 2 energisings.Armature 3 drives push rod 5 to end 51 motions of push rod 5.When the electromagnet horizontally set, the power that acts on workpiece is the power that acts on push rod 5.When electromagnet vertically arranges, one end 51 of push rod 5 pulls downwards in the other end 52 processes, electromagnet also moves downward under himself Action of Gravity Field, the power that makes active force on workpiece comprise to act on push rod 5 and the gravity of electromagnet, the attraction that makes electromagnet produce is fully used, and workpiece more easily is pulled.
New electromagnet of the present utility model can not arrange push rod 5, directly workpiece is fixed on the second free end 32 of armature 3, and the first free end 31 is the force side, also can solve technical problem of the present utility model.
Embodiment in the utility model only is used for the utility model is described, and does not consist of the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection range.
Claims (4)
