Abstract

The utility model relates to a pair of non-hot electric welding tongs, which belongs to a low voltage electric welding tool. That a handle sleeve is not hot is realized by the measures of the reduction of ohm heat, the increase of heat radiation area, the increase of radiation factors, the arrangement of vent holes, etc. The utility model is composed of a left tong, a right tong, a tong shaft, a spring, a handle sleeve, screw nails, a cushion bar, etc. The utility model is characterized in that the pair of non-hot electric welding tongs is provided with a front fastener. A handle sleeve of a pair of ordinary electric welding tongs is very hot after four to six welding bars are welded. The utility model can be continuously operated after forty or sixty welding bars are welded, the torsion force does not exist, and the operation is comfortable. Therefore, the utility model which can accelerate welding speed and can simultaneously improve welding quality is particularly suitable for projects with continuous operation, such as shipbuilding, bridges, construction, etc.

Description

Non-hot electric welding tongs

Not thermoelectric soldering turret belongs to the low tension welding tool.

Electrode holders in the past weld 5 root bead bars, and it is just awfully hot to hold cover, for head it off, occurred in the exhibition of Beijing achievement this year a kind of in left side pincers rear end with nut, 2 awl sheets with the electrode holders that bare wire tightens up, it is introduced, just continuous welding 50 root bead bars generate heat.Its shortcoming is that left side pincers are being with thick electric wire, holds right pincers operation and has about 50～80 kilograms centimetres moment of torsion, and therefore, the operator is more arduous.

The purpose of this utility model is to design such electrode holders, uses it can sequential welding tens root bead bars, and it is also less hot to hold cover, does not have moment of torsion substantially simultaneously, operates comfortable.

The purpose of this utility model is achieved in that at right that end of clamp welding rod and adds longitudinal screw securing member, pad part, and lead is tightened up to reduce ohm heat; Right pincers appearance hacking or open radiating groove or annular knurl or cutting thread increases area of dissipation, simultaneously with the appearance heat-tinting or add coating and increase radiation coefficient; Right pincers rear end, hold the cover front end and open pore and quicken cooling, lead is held in the cover from right side pincers and is drawn.

Owing to taked above-mentioned measure, ohm heat greatly reduces, and radiating condition is greatly improved, and is difficult for heating thereby hold cover, just as the electric iron handle can the continued operation long period; And lead draws from holding in the cover, essentially no moment of torsion, thus operator's comfortable feel, help improving welding quality.

Be elaborated below in conjunction with accompanying drawing.

Fig. 1, Fig. 2 are not thermoelectric soldering turret half sectional views, and Fig. 3 to Fig. 5 is not thermoelectric soldering turret front end half sectional view.Be main describing now with Fig. 1.By shown in Figure 1, not thermoelectric soldering turret by left side pincers (1), right pincers (2), pincers axle (3), a spring (4), hold cover (5), screw (6), filler strip (7) and form, what its characteristics were that end of right pincers (2) folder welding rod vertically has a threaded fastener (8), this part by Fig. 1, Fig. 2, Figure 3 shows that clamp nut (8 '), and by the nut of clamp nut shown in Figure 3 (8 ') for the band inner conical surface, by its be locked plum blossom folder of right pincers (2) folder welding rod one end, bare conductor is clamped; By threaded fastener shown in Figure 4 (8) is taper housing pin (8 ' '), and by Figure 5 shows that screw (8 ' ' '); In addition, threaded fastener (8) can also adopt the screw of head.

Be lined with cone pad (9 ') (by shown in Figure 1) or shape pad complete or burst (9 ' ' ') (by shown in Figure 4) or plain cushion (9 ' ') (press Fig. 2, shown in Figure 5) between threaded fastener (8) and the bare conductor, its effect be convenient to fastening with prevent to become flexible.

Right pincers (2) appearance has rough surface or radiating groove is arranged or annular knurl or screw thread (A), and to increase area of dissipation, simultaneously all right surface oxidation or cladding coating increase heat emissivity coefficient.

The rear end of right pincers (2) and hold on the sleeve pipe (10) between the cover (5) passage (B) is arranged.
