Abstract
The utility model discloses a convenient electric welding mask provided for electric welders, formed by the improvement of a hand-held welding mask, conveniently being fixed on the head of a welder. An observation hole can be automatically (or manually) open and closed by goggles in the mask, and the entrance of electric arc light can be controlled in time. The utility model has the advantages of high precision, simple structure, and easy fabrication, and the cooperating function of two hands can be brought into play, and the labor intensity is reduced. The utility model is reasonable, not only being suitable to protecting eyes of the electric welders, but also being suitable to other uses that strong light needs protecting eyes.
Description
This utility model belongs to instrument class article.
Normally used electric welder's helmet is a fixedly protective eye lens of hand-held, face shield to be covered eyes earlier during welding, and then trigger the weldment arcing with welding rod and play weldering, thereby influence the accuracy of welding, especially in the darker indoor or operation in evening of light, existing shortcoming is more outstanding.And want a hand-held cover, also need other people to hold workpiece under the arm sometimes, the mating reaction of both hands does not obtain performance, and all these directly affects the further performance of welding tool.
This utility model designs in order to overcome above-mentioned weak point just.
Fig. 1, Fig. 2 are respectively the structural representations that makes things convenient for electric welder's helmet and protective eye lens support, and (1) is protective eye lens, and (2) are support, (3) be commutator, (4) be stressed tension type spring, (5) are the fulcrum of bar, and (6) are electromagnet coil, (7) be electromagnet core, (8) be armature, (9) are belt, and (10) are clasp, (11) be the closed type telegraph key, (12) are notch.
Main points of the present utility model are to adopt electromagnet apparatus, make on the travel(l)ing rest protective eye lens automatically (manually) rise and open and close observation port, avoid electric arc light to enter, and the installation belt is provided with clasp on face shield, can easily face shield be buckled on the head, reduce holding of hands.Both sides at the face shield observation port are provided with notch, make protective eye lens along with support slides therein, fix an armature (silicon steel) on the connecting rod, and an end links support (2) by flexible cord, and the electric magnet of U-iron core (7) is installed in the top of armature, strengthen the suction-combining force.The one end series connection commutator (3) of coil (6), playing the change alternating current is unidirectional current, the other end of coil links closed type telegraph key (11), plays the closing function of automatic or manual control protective eye lens.The bottom of support (2) links spring (4), plays protective eye lens and closes observation port naturally.
This utility model is to implement like this.
When electric welding machine is in zero load, the welder transformer secondary coil has the alternating current output of 60V to 70V, resulting unidirectional current is by coil (6) behind commutator (3), the magnetic force of electric magnet generation at this moment is greater than the expansion force of spring (4), at this moment armature (8) is upwards slided by the protective eye lens that bar drives on the support (2) by adhesive, observation port breakdown, but welding person's direct observation pad.
Moment when the welding rod contact workpiece, the welder transformer secondary output voltage is almost nil, and at this moment coil (6) no current passes through, electric magnet magnetic disappears, and spring (4) restores to the original state, and the protective eye lens (1) on the pulling support glides rapidly, close observation port, control electric arc light enters.
When the welding rod starting the arc was welded, the welder transformer secondary coil had 25V to 35V voltage output, and electric magnet produces magnetic force, but since the spring expansion force greater than magnetic force, protective eye lens is still closed observation port, control electric arc light enters.
Welding rod leaves workpiece, and electric welding machine is in zero load, and electromagnetic actuation armature (8) drives protective eye lens breakdown observation port, plays the effect of automatic open close observation port.
When needs are manual, as long as press telegraph key (11), circuit is disconnected, coil (6) no current is by losing magnetism, and spring restores to the original state, and drives the protective eye lens on the support, closes observation port, and control electric arc light enters.
Embodiment of the present utility model adopts 13K-300 type A.C. welder to do supporting.The protective eye lens of selecting for use is long 15 centimetres, the general dark-brown glass of wide 4 centimetres electric welder's helmet, coil (6) is that to select diameter for use be 0.1 millimeter, Q type enamel insulated round copper wire 18000 circles, the diameter of iron core (7) is 0.7 centimetre, magnetic flux density 10000 Gausses' U-shaped silicon steel is made, when the coil both end voltage reaches 50V with regard to the armature (8) on the energy adhesive bar, drive the protective eye lens breakdown observation port on the support, the moment that telegraph key disconnection or welding rod and workpiece disconnect, protective eye lens is just closed observation port (sending early than arc light) immediately.Commutator (3) is to adopt the 2CZ82C diode, carries out bridge rectifier.
Claims (4)
1, a kind of electric welder's helmet that makes things convenient for that forms that improves by hand-held fixed protective eye lens, it is characterized in that having on the face shield belt [9], and the employing electromagnet apparatus, make the protective eye lens [1] that is buckled in a last face shield along with support [2] breakdown and close observation port automatically, the entering of control electric arc light.
2, electric welder's helmet as claimed in claim 1 is characterized in that having on the belt clasp (10).
3, electric welder's helmet as claimed in claim 1, two ends that it is characterized in that said electromagnet coil (6) are connected respectively and are attached at the outfan of the secondary coil of electric welder transformer behind commutator (3) and the telegraph key (11), the armature (8) of iron core (7) on the bar.
4, electric welder's helmet as claimed in claim 1 is characterized in that linking stressed tension type spring respectively on the upper and lower limit of said support (2) and is on the lever of fulcrum with (5).
