Abstract

The utility model relates to a double-push electromagnet whose armature iron can move in a straight line, wherein an electromagnetic coil is arranged in a shell, a left moving core and a right moving core are penetrated into the core holes of the shell, an end cap is fixed on the port of the shell, and a shock absorption mechanism which is conveniently adjusted externally is arranged on the end cap. The utility model can adjust the shock absorption mechanism from the outside of the double-push electromagnet under the condition of free detachment, and facilitates the electromagnet to restore the work effect with low noise. Because the shock absorption mechanism is adopted with the external adjustment, the adjustment is simple, convenient and fast, which meets the use demands of users.

Description

A kind of dual-push electromagnetic iron

Technical field

But the utility model relates to the electromagnet that a kind of armature straight line moves, specifically a kind of dual-push electromagnetic iron.

Background technology

Existing dual-push electromagnetic iron, its structure are to be provided with two solenoids in housing, and cross-under has left and right two moving cores in the core hole of tubular shell, and the housing port is fastenedly connected with left and right two end caps respectively by screw.For overcoming the big problem of work of electromagnet noise, be plugged with some shock structures vertically respectively in the inboard of two end cap, the inner face of the outstanding end cap of the front end of shock structure.When electromagnet energising adhesive, the end face of moving core touches the shock structure exposed junction earlier, and then contacts adhesive with the inner face of end cap.Though the setting of this shock-damping structure can reduce the work noise of dual-push electromagnetic iron, but because the suction-combining force of dual-push electromagnetic iron is very big, very big to the impact wear of shock structure, so need frequent shutdown maintenance, change shock structure.And the blind-hole type inserting mode of shock structure on end cap makes that also replacing is cumbersome.So the maintain and replace workload is big, downtime, length was the outstanding problem that existing dual-push electromagnetic iron exists.

The utility model content

The purpose of this utility model just provides a kind of new-type dual-push electromagnetic iron, to overcome the deficiency that existing dual-push electromagnetic iron exists, satisfies user's user demand.

The utility model is achieved in that a kind of dual-push electromagnetic iron, in housing, be provided with solenoid, cross-under has left and right two moving cores in the core hole of housing, and the housing port is fixedly connected with end cap, and described end cap is provided with the damping of being convenient to from the outside adjusting.So just can under the situation that need not tear machine open, regulate operation to damping, make electromagnet recover low noise work effect again from the outside of dual-push electromagnetic iron.Because to damping is to adopt outside the adjustment, thereby adjustment work is simple and convenient quick, has satisfied user's user demand.

Description of drawings

Fig. 1, Fig. 2 are the structural representations of two kinds of implementations of the utility model.

Embodiment

Embodiment 1:

As shown in Figure 1, the housing 1 of dual-push electromagnetic iron is a cylindrical shape, is provided with two solenoids 7 in housing 1, and cross-under has left and right two moving cores 3 in the core hole of housing 1, is fixedly connected with end cap 2 on the port of housing both sides respectively.Be arranged on a kind of damping on the end cap 2, be on end cap 2, to have the axially extending bore that distributes around the axle center, inner segment at each through hole is plugged with shock structure 5, the outer section adjustment screw 4 that has been threaded at each through hole, the front end of adjusting screw leans on the inner termination of shock structure 5, and the front end of shock structure protrudes in the inner face of end cap 2.

After the jag of shock structure 5 polishes, as long as screw 4 is adjusted in suitable precession, can eject one section shock structure termination again, make dual-push electromagnetic iron recover low noise operational effect.This adjustment mode is very easy, need not tear machine open, and downtime is very short.In addition, this damping makes also that the replacing of shock structure becomes simply, quick, easy row.

3-6 the through hole of sparing cloth around the axle center can be set on two end cap 2, and shock structure 5 can adopt hard, wear-resistant rubber to make, and the inner face of the outstanding end cap 2 of shock structure front end can be expanded between the 2-4 millimeter.

Embodiment 2:

As shown in Figure 2, the housing 1 of dual-push electromagnetic iron is a cylindrical shape, is provided with two solenoids 7 in housing 1, and cross-under has left and right two moving cores 3 in the core hole of housing 1, is fixedly connected with end cap 2 on the port of housing both sides respectively.The another kind of damping that is arranged on the end cap 2 includes pressure strip 8, beam 6, top board 9 and adjusts screw 4 etc., pressure strip 8, beam 6 and top board 9 cross-under successively move on the exposed junction axle of core 3 at dual-push electromagnetic iron, adjustment screw 4 passes pressure strip 8 and is threaded on the end cap 2, top board 9 is crimped on the outside end face of end cap 2, beam 6 is crimped between pressure strip 8 and the top board 9.

Pressure strip 8, beam 6 and top board 9 may be made in circle, and the center jack hole on each is relative.When dual-push electromagnetic iron was switched on adhesive, the reducing shaft shoulder on the moving core 3 promoted top board 9 earlier and compresses beam 6, and the end face of moving core 3 contacts adhesive with the inner face of end cap 2 more then, and the realization damping is fallen hot-tempered.By to adjusting the adjusting of screw 4, can adjust compaction degree to beam 6.Certainly, answer the cross-under spring washer adjusting on the screw 4, get loose preventing.
