Abstract

The utility model relates to an electric arc welding device, particularly to a pair of electric welding pliers used for AC and DC welding. The electric welding pliers mainly solves the problems of waste, short service life and easy damage in the prior art. The pair of electric welding pliers is characterized in that a transition iron part is connected with the bent arm of the electric welding pliers; a welding rod component is clamped by the electric welding pliers, a nose of a copper opening connection wire on a welding power wire is soaked with tin, and is fastened on the transition iron part through a bolt and high-strength spring. The utility model has the advantages of seasonable structure, convenient use and maintenance and material economization.

Description

A kind of electrode holders

Technical field:

The present invention is a kind of arc-welding apparatus, is a kind of electrode holders that the alternating current-direct current welding is used that are used for.

Background technology:

The electrode holders of domestic and international market sale at present comprise electric welding vice body (comprise clamping welding rod part, be also referred to as down mouth), curved boom, handle, electrode holders mouth mouth mask and spring composition up and down.The electric welding vice body directly is connected with curved boom plays a supporting role, and source of welding current line is inserted in the electric welding vice body barrel shell, by pressing plate that source of welding current line pressure is tight with 6 millimeters double-screw bolts.This structure, shortcoming is that electric welding vice body and source of welding current line are copper materials, and double-screw bolt and pressing plate are steel, material coefficient of expansion difference, will cause during welding that electric welding vice body and source of welding current line are loosening, loose contact, become heat generating spot, the electric welding vice body can generate heat during welding, because source of welding current line is an annealed copper wire, be connected insecure heating with electrode holders, can make annealed copper wire be easy to oxidation, cause conductive capability to descend, cause vicious circle, can only cut out oxidation place of source of welding current line at last and go, cause source of welding current line to use shorter and shorter.In addition, electric welding vice body clamping welding rod position is the place of the easiest damage, and after this position was damaged, electrode holders just can't use, and whole like this electrode holders have just been scrapped, and cause very big waste.

Summary of the invention:

The purpose of this utility model provides a kind of novel electrode holders, and is short to overcome the fragile life-span of present technology, wasting problem.

Concrete technical scheme of the present utility model: the transition ironware is connected with the electrode holders curved boom, and copper opening wiring nose wicking is fastened on the transition ironware by bolt, high-strength spring pad on electrode holders clamping welding rod parts, the source of welding current line pressure.Electrode holders clamping welding rod parts set up, and can independently change.

The beneficial effects of the utility model are rational in infrastructure, use easy to maintenance, economical with materials.Specifically: the position of (1) electrode holders clamping welding rod is the place of easy damage, replace the electric welding vice body to play support and be connected effect with the transition ironware, the electric welding vice body just can only be done the parts of clamping welding rod, can be easy to after the damage change, can save the copper material more than 60%, reduced energy resource consumption, parts can be changed after damaging in the position of electrode holders clamping welding rod, the permanent use.

(2) the present invention is owing to used the transition ironware, adopt the connected mode of bolt high-strength spring pad, the high-strength spring pad remains the pressure to this position, former electrode holders have been overcome owing to becoming flexible that material coefficient of expansion difference is brought, thoroughly solved the problem of electrode holders and source of welding current line junction heating, copper opening nose and wicking on the source of welding current line pressure have so just guaranteed that source of welding current line can be more with not short more, save material, also improved electric welder's labour intensity.In the use, non-scald on hand.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Accompanying drawing 1 is the connection diagram of clamping welding rod parts, power line and transition piece;

Accompanying drawing 2 is structural representations of clamping welding rod parts;

Accompanying drawing 3 is structural representations of excessive ironware;

Among Fig. 1,1, clamping welding rod parts, 2, bolt, 3, transition piece, 4, power line

Among Fig. 2,5, clamping welding rod parts fixing hole

Among Fig. 3,6, the fixing hole of electrode holders curved boom of transition piece

Know that by Fig. 1,2,3 hole 6 is connected transition piece 3 with the electrode holders curved boom; Copper opening nose on clamping welding rod parts 1, the source of welding current line 4 is fixed on the transition piece 3 with bolt 2.

The specific embodiment:

The electrode holders curved boom with after the hole 6 of transition ironware 3 is connected, source of welding current line 4 is pressed copper opening nose wicking, be fastened on the transition piece 3 with 12 millimeters bolts of hole 5 usefulness diameters, plain cushion, the high-strength spring pad of electrode holders clamping welding rod parts 1, will be inserted in through the paper handle of overcuring and flame treatment again and be fixed on the transition piece 3.Load onto electrode holders mouth mouth mask and spring up and down at last.

Claims

1. electrode holders, comprise curved boom, handle, electrode holders mouth mouth mask and spring composition up and down, it is characterized in that the transition ironware is connected with the electrode holders curved boom, copper opening wiring nose wicking is fastened on the transition ironware by bolt, high-strength spring pad on electrode holders clamping welding rod parts, the source of welding current line pressure.

2. electrode holders according to claim 1 is characterized in that clamping welding rod parts set up, and can independently change.
