Description
Technical field:
The present invention relates to a kind of manual electrode holders, specifically is a kind of electrode holders with anti-scald performance.
Background technology:
The member of electrode holders mainly is made up of jaw, up knob, spring, link, insulated handle and the electric conductor that is installed in the insulated handle; Electrode holders are exactly by soldering turret mouth clamping welding rod,, are produced electric arc between welding rod and welding base metal and dissolve welding rod and realize welding to a large amount of electric current of welding rod transmission by the soldering turret electric conductor.The electric conductor of existing electrode holders all is to adopt copper material to make basically, its body is a strip, the electric conductor rear end of strip is provided with the retainer plate that is used to connect with the wiring pressing plate of fixed power source cable, the front end of electric conductor is the lower clamp nozzle of electrode holders, curve two flangings under the both sides of electric conductor leading portion, make the leading portion of electric conductor become U type groove, two curved down flangings are directly conflicted on the insulated handle inwall, and with screw electric conductor are fixed in the insulated handle.There are three defectives in this version, the one, because the two following curved flangings of electric conductor directly contact with insulated handle, when electrode holders after continuous welding a period of time, produce a large amount of heats of electric arc between welding rod and welding base metal, and electric conductor itself is directly transferred on the insulated handle by two flangings of bending down by the heat that electric current produces, the insulated handle surface temperature can be reached more than 40 degree, it is very hot that the operator feels, make the operator have to stop, treat to continue welding again after the handle cooling, thereby influenced job schedule; The 2nd, electric conductor is to be fixed on the handle by screw, and head of screw is emerging in the screw hole of insulated handle, has the hidden danger that is absolutely unsafe, if do not note, operator's finger is touched easily and appeared the head of screw that has in the screw hole, and electric shock accidents takes place; The 3rd, electric conductor is whole strip, and the copper material consumption is many, has increased the cost of manufacture of electrode holders.
Summary of the invention:
One of the technical problem to be solved in the present invention is, problem at above-mentioned prior art existence, a kind of scalding-resistant electric-welding pliers is provided, this scalding-resistant electric-welding pliers can block a large amount of heats that produce electric arc between welding rod and welding base metal, and electric conductor itself passes through the curved down directly conduction on insulated handle of two flangings by the heat that electric current produces, to reach the temperature that reduces on the insulated handle, make the operator can not feel very hot, improved operator's labour intensity.
Two of the technical problem to be solved in the present invention is, provides a kind of and can eliminate in order to the fixing electric conductivity of the head of screw of the screw of electric conductor on insulated handle, and security is scalding-resistant electric-welding pliers preferably;
Three of the technical problem to be solved in the present invention is to provide a kind of copper consumption that can reduce electric conductor, the scalding-resistant electric-welding pliers of the cost of manufacture of reduction electrode holders.
Technical solution of the present invention is that a kind of scalding-resistant electric-welding pliers with following structure is provided.
A kind of scalding-resistant electric-welding pliers, comprise jaw, up knob, spring, link, insulated handle, electric conductor, electric conductor is to be fixed in the insulated handle by preceding mouth hold-down screw and electric conductor hold-down screw, is characterized in, an insulation heat-insulating cushion block is set between the inwall of electric conductor and insulated handle.
After adopting above structure, compared with prior art, the present invention has the following advantages: because an insulation and a heat-insulating cushion block is set between the inwall of electric conductor and insulated handle, make a large amount of heats that produce electric arc between welding rod and welding base metal, and electric conductor itself can not be directly transferred on the insulated handle by the heat that electric current produces; So handle is difficult for hot, improve working conditions and labour intensity, increase work efficiency, be a kind of comparatively desirable improvement product.
The present invention also has following feature and advantage:
Described is that insulation head of screw or head of screw are surrounded by one deck insulating barrier outward in order to the head of screw that electric conductor is fixed on the electric conductor hold-down screw in the insulated handle.This structure can be eliminated the hidden danger that the head of screw that had electric conductivity originally exposes generation, for the use of electrode holders provides security guarantee preferably.
Described electric conductor is set to the electric conductor assembly, the electric conductor assembly is made up of jaw copper conducting block, jaw electric conductor cushion block and clamp backbone block, jaw electric conductor cushion block is that ferrous material is made and is adjacent to below jaw copper electric conductor, and the clamp backbone block is that ferrous material is made and is spirally connected with jaw copper electric conductor rear portion.This structure can be saved copper product greatly, reduces the cost of manufacture of electrode holders.
Described insulation heat-insulating cushion block is glass fiber reinforced unsaturated polyester plastic insulation and heat-insulating cushion block or insulation of phenolic resin glass fibre reinforced mould plastic and heat-insulating cushion block.Glass fiber reinforced unsaturated polyester plastic or phenolic resin glass fibre reinforced mould plastic have insulation, fire-retardant, heat insulation superperformance, so, this structure, make a large amount of heats that produce electric arc between welding rod and welding base metal, and electric conductor itself can not be directly transferred on the insulated handle by the heat that electric current produces; Thereby improved working condition and labour intensity, increased work efficiency.
The insulation head of screw of described head of screw is set to Merlon insulation head of screw or is surrounded by one deck Merlon insulating barrier outside head of screw, or the insulation head of screw of head of screw is set to ABS plastic insulation head of screw or head of screw is surrounded by one deck ABS plastic insulating barrier outward, or the insulation head of screw of head of screw is set to polypropylene PP insulation or head of screw is surrounded by one deck polypropylene PP insulating barrier outward.Merlon, ABS plastic, polypropylene PP have good insulation and fire resistance, and therefore, this version can be eliminated the hidden danger that the head of screw that had electric conductivity originally exposes generation, for the use of electrode holders provides security guarantee preferably.
