Abstract
The invention belongs to a device element of the electric field, relating to a pushing type electromagnet. The pushing type electromagnet is composed by a shell, an immovable iron, a movable iron and an electromagnetic coil, characterized in that a soft magnetic metal bar is inlayed at a head end part of the movable iron. When the electromagnetic coil is electrified, the electromagnetic coil and the immovable iron surrounding the electromagnetic coil generate powerful suction of magnetic field to suck the movable iron into a space surrounded by the immovable iron and the electromagnetic coil, in order to impact a spring and a push rod of a rear part executing mechanism of an electromagnet so that the executing mechanism completes the production; when the electromagnetic coil is broken off, due to the effect of the soft magnetic metal bar inlayed at the head end part of the movable iron, remanence of the movable iron of the pushing type electromagnet is almost zero, the spring and the push rod of the rear part executing mechanism of the electromagnet resets rapidly under the influence of the movable iron, the response speed is quite fast and movement frequency of the electromagnet is accelerated, so the pushing type electromagnet is applicable for the working demands of automatic control in high-speed product line and improves the working efficiency of the automatic product line.
Description
Technical field
The invention belongs to a kind of electric elements of electricity field, relate to a kind of push electric magnet.
Background technology
Electromagnet is a kind of electric energy to be converted into the electric elements of rectilinear motion mechanical energy, and its feature is: add the simple in structure of switching mechanism than motor during rectilinear motion, cost is low, and noise is little, and the life-span is long.Utilize that electromagnetism is ferromagnetic to be had, do not have, can use the switching Current Control; The characteristics that the size of magnetic can be controlled with the number of turn of the power of electric current or coil, in automatic production line product external packaging field, a large amount of use electromagnet carry out production control.Present widely used push electric magnet is by housing, quiet iron, moving iron and solenoid are formed, when solenoid is switched on, spring and push rod that the suction that solenoid and the quiet iron that surrounds solenoid produce magnetic field will move inner impact electromagnet rear portion, the space actuator that the iron inspiration surrounds by quiet iron and solenoid make actuator finish production operation, when solenoid cuts off the power supply, the magnetic field that the quiet iron of solenoid and encirclement solenoid produces disappears, the spring and the push rod of electromagnet rear portion actuator reset iron, like this, utilize the logical of solenoid, outage produces having of magnetic field, do not have the reciprocating motion of the moving iron of control, thereby realize the production control of actuator.In industries such as pharmacy, food, printing, tobaccos, the flowing velocity of product is very fast on the high-speed production lines, push electric magnet of the prior art is because of also leaving more remanent magnetism on the moving iron in the back that cuts off the power supply, and response speed is difficult to finish the accuracy rate that product on production line is at a high speed controlled more slowly.
Summary of the invention:
It is few to the purpose of this invention is to provide the remanent magnetism that stays on the moving iron in a kind of back that cuts off the power supply, the push electric magnet that response speed is fast.
Purpose of the present invention adopts following technical proposals to finish: described push electric magnet is made up of housing, quiet iron, moving iron and solenoid, is characterized in inlaying a soft magnetic metal bar at the cephalic par of moving iron.When solenoid is switched on, spring and push rod that solenoid and the suction that surrounds the strong magnetic field that the quiet iron of solenoid produces will move inner impact electromagnet rear portion, the space actuator that the iron inspiration surrounds by quiet iron and solenoid make actuator finish production operation, when solenoid cuts off the power supply, the magnetic field that the quiet iron of solenoid and encirclement solenoid produces disappears, because the effect of the soft magnetic metal bar that moving iron cephalic par is inlayed, remanent magnetism on the feasible moving iron seldom, almost nil, moving iron resets very soon under the effect of the spring of electromagnet rear portion actuator and push rod, like this, utilize the logical of solenoid, outage produces having of magnetic field, when not having the production control of the reciprocating motion realization actuator that controls moving iron, the response speed of electromagnet is very fast, can finish the accuracy rate that product on production line is at a high speed controlled preferably.
The remanent magnetism that stays on the moving iron in push electric magnet outage provided by the present invention back is few, to the switching electricity of solenoid, response speed is very fast, has accelerated the operating frequency of electromagnet, adapt to the high-speed production lines job requirement of control automatically, improved the operating efficiency of automatic production line.
Description of drawings
Fig. 1 is the structural representation of push electric magnet provided by the present invention.
Among the figure: 1, electromagnet housing, 2, quiet iron, 3, moving iron, 4, solenoid, 5, the soft magnetic metal bar, 6, rivet, 7,9, the elastic caoutchouc liner, 8, for the hole of the push rod turnover of actuator.
Embodiment
Below in conjunction with description of drawings enforcement of the present invention.Push electric magnet provided by the present invention as shown in Figure 1 is made up of electromagnet housing 1, quiet iron 2, moving iron 3 and solenoid 4, has inlayed soft magnetic metal bar 5 at the cephalic par of moving iron 3.When solenoid 4 energisings, solenoid 4 and the suction that surrounds the strong magnetic field that the quiet iron 2 of solenoid produces will move in the space that iron 3 inspirations surround by quiet iron 2 and solenoid 4, and the spring and the push rod of bump electromagnet rear portion actuator make actuator finish production operation.Because the effect of the soft magnetic metal bar 5 that the cephalic par of moving iron 3 is inlayed, make when solenoid cut off the power supply the remanent magnetism on the moving iron seldom, remanent magnetism is almost nil, moves iron and reset very soon under the effect of the spring of electromagnet rear portion actuator and push rod.When the reciprocating motion that have, do not have control moving iron of this push electric magnet in the switching electricity generation magnetic field that utilizes solenoid realizes the production control of actuator, the electromagnet response speed is very fast, response speed≤0.2 second, be fit to the requirement of high-speed production lines production technology, improved the service efficiency of electromagnet, simultaneously, improved the operating efficiency of automatic production line.Push electric magnet middle shell 1 provided by the present invention adopts aluminium alloy to make, the hole 8 for the spring of actuator and push rod turnover is left at the rear portion of quiet iron 2, quiet iron 2 adopts silicon steel sheet fixedly to be formed by rivet with moving iron 3, makes at the soft magnetic metal bar 5 usefulness permalloys that the cephalic par of moving iron 3 is inlayed.
Claims (2)
