Abstract

The utility model relates to a carbon dioxide gas welding cable with an aluminum core as a power conductor. The current supply wire is an aluminum wire, so the weight of the cable is decreased greatly; through improving the cable construction of a welding machine, the mobility, the transportability and the durability of the cable are improved. The utility model is provided with a thermal-plastic rubber outer layer 1 with heatproof quality, a gas supply tube 2 positioned at the center position of the cable of the welding machine, a power conductor wire 3, a control wire 4 positioned in the power conductor wire 3 and a nonwoven 5 which enwraps the exterior of the power conductor wire 3; the power conductor wire positioned in the rubber is composed of fifteen monomeric wires, and each monomeric wire with diameter of from 0.18 to 0.60 mm is formed by winding the aluminum wire. Compared with the carbon dioxide gas welding cable with copper as the power conductor wire, the weight is reduced by about 35%; because of the characteristic of the carbon dioxide gas welding wire, the welding wire is generally longer, and therefore, the transportability and the operational performance of the welding wire are improved.

Description

With the aluminium core is the carbon dioxide welding cable of power conductor

Technical field

The utility model relates to a kind of carbon dioxide welding cable, and particularly relating to the aluminium core is the carbon dioxide welding cable of power conductor.

Background technology

Generally speaking, carbon dioxide welding prolongs welding cable if desired, so, need not mobile device, just can directly carry out weld job at overhead very high structures or work-yards such as building, yard, therefore, its frequency of utilization grows with each passing day.

The structure in the past of above-mentioned carbon dioxide welding cable as shown in Figure 3, it is made of rubber outer 31, feed tube 32, current supply line 33 and control line 34 with job control facility.But, because being a kind of current supply line 33, this mixes the structure of inserting with control line 34, though control line is covered, but, when loading is passed through, cable has been applied crunch because loadings such as the vehicle of job site and conveying arrangement are huge, in this case, make the lining of control line impaired, swinging cross takes place with control line 34 in power lead 33, and existence may cause welding the situation of function paralysis.

In addition, in order to remedy defective, as shown in Figure 4, another welding cable structure has been proposed as the carbon dioxide welding cable of above-mentioned Fig. 3 structure.This structure is made of leader cable 45 and relief cable 46, and wherein, leader cable 45 comprises rubber outer 41, feed tube 42, power lead 43, and relief cable 46 is the cables that control line 44 are provided with in addition formation in leader cable 45 outsides.But this structure also has problems, promptly, because relief cable 46 protrudes and card is loaded on leader cable 45 surfaces, under the externally less strength effect, the obedient load of relief cable 46 connects and will drop, cause that thus cable is impaired, still have the situation that may cause welding function reduction and paralysis.

In order to address this problem, develop structure cable as shown in Figure 5 again, this cable is in rubber outer 51 inside feed tube 52 to be set, one side is provided with control line 54 in the inside of power lead 53 and cable.But the shortcoming of this cable is, because 54 of control lines are arranged at a side of cable, when using cable at the scene, its flexibility descends, and operator's sense of fatigue strengthens, and, mobile, also very inconvenient when transporting cable.In addition, the same with above-mentioned conventional art, because loadings such as the vehicle of job site and conveying arrangement are huge, when loading is passed through, cable is applied immense pressure, in this case, exist the lining of control line impaired, the problem of power lead and control line generation swinging cross.

In addition, in order to address this is that, develop structure as shown in Figure 6 again, this structure is that feed tube 62, power lead 63 and control line 64 are set respectively in rubber outer 61, still, this structure is owing to be to be provided with respectively, the cable flexibility is descended, and operator's sense of fatigue strengthens, when cable length is very long, move, flexibility can descend during the transportation cable, also has unsatisfactory part.

The utility model content

The utility model develops in order to solve the problems of the technologies described above just, its technical task is a kind of new cable structure of exploitation, promptly, use reduces the material of carbon dioxide welding cable quality as current supply line, reduce the weight of the carbon dioxide welding cable of the long distance of needs significantly, thus the mobility and the operation that have improved welding cable.

The utility model another one technical task is a kind of structure that increases carbon dioxide welding cable flexibility of exploitation.

According to above-mentioned technical problem, it is the carbon dioxide welding cable of power conductor with the aluminium core that the utility model provides a kind of, is that it comprises in the carbon dioxide welding cable: thermal endurance thermoplastic elastomer skin; Feed tube is positioned at the centre of bonding machine cable; Power lead in above-mentioned rubber inboard, has 15 monomer lines and constitutes, and every monomer line is twined by aluminum steel and forms, and diameter is 0.18～0.60mm; Nonwoven fabrics, the outside of wrapping up above-mentioned power lead; Control line is between above-mentioned power lead.

The utility model carbon dioxide welding cable, be a kind of be the carbon dioxide welding cable of power conductor with the aluminium core, its current supply line is an aluminum steel, and the weight of cable is descended significantly, by improving the structure of bonding machine cable, improved mobility, transportation property and the durability of cable.
