Description

A kind of compound parallel double coaxial high current welding cables of pneumoelectric

Technical field

The utility model relates to wire and cable field, the compound parallel double coaxial high current welding electricity of specifically a kind of pneumoelectric Cable.

Background technique

With the rapid development of raising and the industrial automation of occupational health standard, automates gas shielded arc welding connection technology and exist It is more and more common in industry.Bigger welding current and higher welding efficiency are needed when welding Large-Scale Equipment.Welding cable In normal work, cable itself can generate heat in high current transmission process, while as the frequent movement of cable will cause Distortion of the cable, cable is damaged with tracheae when serious causes being greatly reduced for welding difficulty, efficiency decline and cable service life.

Utility model content

The utility model in order to solve the existing problems, provides a kind of compound parallel double coaxial high current welding electricity of pneumoelectric Cable has superior heat radiation characteristic, and has good resistance to movement while the welding current of welding cable is greatly improved Performance.

A kind of compound parallel double coaxial high current welding cables of pneumoelectric described in the utility model, including two arranged in parallel Coaxial cable core, dowel is equipped between two coaxial cable cores, and structure is integrally formed by dowel；The dowel center Place is equipped with the nylon fiber that diameter is 0.1~0.2mm；The dowel length be 2.0mm~3.0mm, with a thickness of 0.2mm~ 0.4mm；The coaxial cable core is made of one, center tracheae and extratracheal coaxial copper conductor with silicone rubber jacket.

It is further improved, the ultra-fine copper free wire concentric stranding group that the copper conductor is 0.10mm~0.15mm by diameter At.

It is further improved, the tracheae is made of thermoplastic polyurethane elastomer material.

The utility model beneficial effect is:

1, this cable passes through double tracheae parallel coaxial structures, and the welding current of cable greatly improved；Increase cable Heat dissipation area has better heat sinking function.

2, this cable air is manufactured using thermoplastic polyurethane elastomer material, has excellent resistance to movement, wear-resisting, loss prevention Bad performance.

3, the dowel center among this cable parallel construction and cable is covered with nylon fiber reinforcement, is provided with this cable Good resistance to travelling performance.

4, the utility model construction of cable is simple, with excellent heat dissipation while greatly improving the welding current of cable Property, parallel construction protects cable that frequent folding and unfolding bring is answered to damage well；Substantially increase the welding efficiency and use of cable Service life has reached good economic benefit and social benefit.

Detailed description of the invention

Fig. 1 is this utility structure schematic diagram.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

As shown in Figure 1, the utility model is a kind of compound parallel double coaxial high current welding cables of pneumoelectric, including two are put down The coaxial cable core 1 of row arrangement, equipped with dowel 2 between two coaxial cable cores, and is integrally formed structure by dowel；The company It connects and is equipped with nylon fiber 3 at muscle center；The dowel length is 2.0mm~3.0mm, with a thickness of 0.2mm~0.4mm；Institute The coaxial cable core stated is made of one, center tracheae 1-1 and extratracheal coaxial copper conductor 1-2 and silicone rubber jacket 1-3；Institute The center that dowel is arranged in nylon fiber is stated, diameter is 0.1~0.2mm；The dowel length is 2.0mm~3.0mm, With a thickness of 0.2mm~0.4mm；

The coaxial copper conductor is made of the ultra-fine copper free wire concentric stranding that diameter is 0.10mm~0.15mm；It is described Tracheae be made of thermoplastic polyurethane elastomer material.

Embodiment:

The specific structure of the utility model: the coaxial conductor of the cable first uses 500 type strand winders, and bundle strand diameter is 0.10mm 128, copper wire, same core bundle strand at specification be 1.0mm²Flexible conductor；JL400/36+36 type same core armoring machine is reused with straight Diameter is 35 1.0mm centered on the TPU tracheae of 20mm²Flexible conductor around diameter be 20mm polyurethane tracheae carry out same core It is made by twisting coaxial cable core；Two cable cores are placed in parallel together with the nylon fiber that a diameter is 0.1mm, are squeezed with XJW-90 Rubber machine extrudes one layer of silicone rubber jacket by dedicated parallel molds, with a thickness of 2.2mm；Dowel length × thickness is 0.3mm*2.0mm； The saturated vapor pipeline continuous vulcanization that cable is 105 meters by length.

The utility model cable is by correlation performance parameters test and 70 squares of common welding machine cable comparisons: this cable exists At 20 degrees Celsius, conductor DC resistance is 0.246 Ω/kM；It improves than welding of common welder cable conduction performance more than 10%；This reality With novel cable in 100% water holdup operating condition of welding machine, when length is 10 meters, current-carrying capacity is 318 amperes；Than common welding cable 265 amperes improve 20%；The utility model cable is 250 ampere-hours in welding rated current, and cable temperature is 42.1 degree, often Rated current is being welded as 250 ampere-hours with welding machine cable, and cable temperature is 62.5 degree, and difference is obvious, and (length is all 10 Rice), the aging of cable cover(ing) is slowed down significantly, saves a large amount of energy.

In actual use, the utility model cable welding electric current is big, folding and unfolding is convenient, resistance to movement, resist bending, economic benefit It is obvious with social benefit.

There are many utility model concrete application approach, and the above is only the preferred embodiment of the utility model, should It points out, for those skilled in the art, without departing from the principle of this utility model, can also make Several improvement out, these improvement also should be regarded as the protection scope of the utility model.
