Description

Electromagnetic descaling machine for welded seam

The utility model relates to the electromagnetic type cable connector of a kind of electromagnetic type deseaming machine and adapted thereof.

The crowd knows, the groove cleaning is to use wire brush before the weld seam weldering at present, or electronic wire wheel, electric wheel, or facility such as pneumatic wire wheel, air sander.With the manual brush of wire brush, inefficiency not only, labour intensity is big, and the effect of cleaning rust, oxide skin and other impurity is also poor; Electronic wire wheel or emery wheel owing to adopt the rotary electromotor principle, must connect power supply in addition, and majority is 220 volts voltages, and this increases not only that lead-in wire bothers and be dangerous; With pneumatic wire wheel or emery wheel, because the most non-compressed airs in welding place, it is not only greatly expensive that other joins air compressor machine, and use also inconvenient.The more important thing is that the cleaning of removing slag of weld seam postwelding needs also still that the Hammer head is manual to be struck, the also handy manual manipulation of splash removes.This makes in the whole welding process, and the required facility of weld cleaning are wide in variety, uses miscellaneously, and time-consuming, and labour intensity is big, and welding quality is also influenced.

Task of the present utility model provides a kind of electromagnetic type deseaming machine, it is a power supply with the voltage of welding machine output between welding gun and workpiece, also can adopt other power supplys, the collection wire brush, the Hammer head, manual manipulation, the function of facility such as electronic or pneumatic wire wheel is in one, simple in structure, facility are light and handy, groove eliminated rust before both having can be used for the weld seam weldering, oxide skin and other impurity, make its metal luster, can be used for the postwelding weld cleaning again, Ex-all welding slag and general splash, in addition to the difficult bottoming layer of removing of Hammer head or other because the locus restriction causes the weld seam of slagging-off difficulty, also Ex-all welding slag fast.This machine also can be used for removing rust, oxide skin and other impurity etc. of the metal material surface of other different shapes simultaneously.Because this machine directly inserts the voltage between welding gun and workpiece, do not need the energy and lead-in wire in addition, facility are single, easy to use, handling safety had both alleviated welder's labour intensity, having improved weld cleaning efficient, guaranteed cleaning quality again, is the comparatively desirable facility of weld cleaning.

The electromagnetic type cable connector of adapted when the utility model also provides the magnetic-type deseaming machine of can powering to be used for the steel workpiece simultaneously.This joint places the steel surface of the work, can arbitrarily move at surface of the work when cutting off the power supply in the loop, contacts well with workpiece during energising, has saved the fixedly line between electromagnetic type deseaming machine and steel workpiece, makes it easy to use.This joint also can be used as the removable joint between electrical appliance and steel part in other safe voltage loops simultaneously.

The utility model be achieved in that have in electromagnetic type deseaming machine outside one can be for not only as the power supply input but also as welding gun holder and a junction block that connects the electromagnetic type cable connector of the manual electric arc welding welding gun clamping of operating grip.Power switch, gauge tap, solenoid, static iron core, moving iron core and spring etc. are equipped with in portion within it; When the welding machine output voltage is added on the electromagnetic type deseaming machine, turn on the power switch, gauge tap promptly produces periodically break-make, under the effect of solenoid and static iron core, moving iron core is produced stronger periodicity axial magnetic suction, because moving iron core can be in axial sliding, spring shaft makes iron core produce axial back and forth movement to the effect of restoring force in addition.Gauge tap can be made by the contact switch of moving iron core drive or the non-contact switch of electronic component control.Moving iron core can be made by a kind of soft magnetic materials, also can by soft magnetic materials and paramagnetic or diamagnetic material is alternate makes, and when making the solenoid energising moving iron core is had stronger axial magnetic suction.A sleeve is housed in the bottom of electromagnetic type deseaming machine, cluster is housed by the draw point of loose " pin " shape that holds together of grid orifice plate in the tube, greatly head-up, the upper end is pressed with the iron block of an activity, when moving iron core is made quick back and forth movement, just in time hit on movable iron block, the movable iron block that is hit makes draw point family produce impact shock at every turn.The draw point bunch lower end of vibration is put into the weld groove surface, gets final product Ex-all rust, oxide skin and impurity thereof, be put into the postwelding face of weld, can Ex-all welding slag and splash.In addition, at electromagnetic type deseaming machine one end piston, cylinder, intake valve, air bleeding valve are housed, piston is driven by moving iron core and make back and forth movement in cylinder, because the effect of intake valve and air bleeding valve, air is entered from air inlet, after parts such as process solenoid play cooling effect, blow out from the sleeve lower end again, remove by the grit on cleaning surface.

On the electromagnetic type cable connector solenoid is housed, an end and the lead-in wire of solenoid join, and the other end and copper contact join, and solenoid is enclosed within on the iron core, and the shape of iron core makes that magnetic loop must be through closed its magnetic resistance minimum of steel workpiece; Copper contact is contained in the bottom of electromagnetic type cable connector, and its outer contacting face that contacts with the steel workpiece can be made one or more geometry; Insulation board or dielectric film are housed between copper contact and iron core, outer cover, make between copper contact and iron core, outer cover and insulate.Outer cover is positioned at the top of insulation board or dielectric film, the periphery of iron core and solenoid, the outer surface of outer cover is made up of curved surface, the shape of this curved surface makes the center of gravity of electromagnetic type cable connector all the time between this normal to a surface and copper contact, make when the electromagnetic type cable connector is in free state that copper contact can have excellent contact with the steel workpiece of horizontal positioned all the time.Lead-in wire is positioned on the crossing contour of and the plane of crossing electromagnetic type cable connector center of gravity parallel with copper contact outer contacting face and outer cover.When between lead-in wire and steel workpiece voltage being arranged, the electromagnetic attraction that solenoid produced is pressed in the steel surface of the work tightly with copper contact, makes it allow bigger electric current and passes through; When the loop cut off the power supply, electromagnetic attraction disappeared, and the electromagnetic type cable connector can arbitrarily move.

Use the electromagnetic type cable connector of electromagnetic type deseaming machine provided by the utility model and adapted thereof, the manual electric arc welding welder has welded a root bead bar, lose discard electrode after, picking up the electromagnetic type deseaming machine with welding gun can be clean with weld cleaning.Argon arc welding, CO ₂Welders such as weldering, Lincoln weld utilize the dedicated handle similar to the manual electric arc welding welding gun to use equally.
