Abstract

The utility model relates to a pair of low-temperature welding pliers for manual arc welding, comprising a dielectric sealing handle 5 and an operating handle 11. A power supply clamping plate 4, a pressing jaw clamping plate 2 and a jaw cover 1 are fixed at the front ends of the two handles, a power supply cable conductor 12 which penetrates in the operating handle is connected to the power supply clamping plate, the power supply cable conductor and the power supply clamping plate are welded and fixedly connected after fastening by a binding wire 8, and heat emission holes 13 which emit the heat of the clamping plate are arranged on the jaw cover. The utility model which has the advantages of simple structure, good radiation effect, slow temperature rise of the handle, etc. is especially suitable for long-playing use when workers carry out high current arc welding.

Description

Manual low-temp electrode holder for arc welding

The utility model relates to a kind of manual arc soldering turret, particularly a kind of low temperature manual arc soldering turret that can use lastingly.

Existing manual arc soldering turret, long-term existence handgrip temperature height, appearance and size is big, the big deficiency that waits of weight, the labour intensity that causes the electric welder to bear is big, soldering turret scalds one's hand quick heating, uses very inconvenient, a kind of electrode holders of non-scald on hand are disclosed in CN2038436U, it is to have louvre on handle, and outer the putting on the handle also have louvre, though it can reduce the part temperature rise on the handle, but can not reduce the temperature rise at jaw place, and the jaw clamping plate are connected not firm with cable, make handle very fast because of electrothermal heating, influence the continuous use of electric arc soldering turret.

The purpose of this utility model designs a kind of simple in structure exactly, the low temperature manual arc soldering turret that the handle temperature rise is slower.

The purpose of this utility model realizes by following structure: low temperature manual arc soldering turret, include the clamping plate that compress jaw, power supply clamping plate and jaw lid, insulate heat insulation handle and in the operating grip of power cable is arranged, it is characterized in that: be that to tightly wrap the back welding fixing and closely link together by pricking silk between power supply jaw clamping plate and the cable, cover at jaw and also to be provided with louvre, so that when using the heat on the jaw clamping plate by the louvre part of scattering and disappearing, in order to stop the heat on the power cable to be directly delivered on the operating grip, on power cable, can overlap a collet, make to form the annular air cavity between the overcoat of thermal insulation layer and operating grip, utilize air to reach heat insulation purpose.

The utility model compared with prior art has simple in structure, and the handle temperature rise waits advantage slowly, and after tested continuous operation a few hours on big electric current, the handle temperature has only about 40 ℃, is fit to generally promote the use of.

Description of drawings of the present utility model is as follows:

Fig. 1 is a structural representation of the present utility model.

Among the figure: 1, jaw lid, 2, compress the jaw clamping plate, 3, screw, 4, power supply jaw clamping plate, 5, the heat insulation handle that insulate, 6, screw, 7, helical spring, 8, prick silk, 9, prick silk, 10, cover in heat insulation, 11, operating grip, 12, power cable, 13, louvre, 14, louvre, 15, handle jacket, 16, air chamber.

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in Figure 1, the heat insulation handle 5 of insulation that the utility model includes operating grip 11 and controlled by helical spring 7 elasticity, at intrinsic jaw clamping plate 2 and the power supply jaw clamping plate 4 of compressing of handle front end, it is characterized in that: be to tighten the back by bundle silk 8 to connect dead admittedly by pricker or brazing between power supply jaw clamping plate and the power cable, on the lid of the jaw on each jaw clamping plate 1, can be provided with louvre 13, on cable, be with heat insulation in the cover 10, form ring-type air chamber 16 in heat insulation between cover and the handle jacket 15, at cable front end and rear portion, power supply clamping plate junction, have and prick silk 9 cable is tightened, produce electric heating to prevent it.

Claims (3)

1, a kind of low temperature manual arc soldering turret, include heat insulation handle 5 of insulation and operating grip 11, at the intrinsic power supply clamping plate of handle front end 4 with compress jaw clamping plate 2 and jaw lid 1, insulating has the power cable 12 that links to each other with the power supply clamping plate in the heat insulation handle, it is characterized in that: power supply clamping plate and cable tightly wrap the back solid welding together by pricking silk 8, have covered louvre 13 at jaw.

2, low temperature manual arc soldering turret as claimed in claim 1 is characterized in that: be with collet 10 outside power cable.

3, low temperature manual arc soldering turret as claimed in claim 1 is characterized in that: at power cable front end and rear portion, power supply clamping plate junction the bundle silk 9 of tightening cable is arranged.
