Abstract
The utility model relates to a combined welding cable which is a secure, convenient and energy-saving secondary welding cable for an AC / DC electric welding machine of manual electric arc. The utility model has (1) a connectable welding cable and (2) a fixed welding cable. When the fixed welding cable is used, an electrode holder and a ground wire arrive in the welding job site synchronously, which can avoid the insecure situation that a device and a pipeline are used as the substitutional secondary loop. So when welding, the releasing and the straightening of the welding cable can be guaranteed, and the unnecessary voltage drop caused by impedance loss dose not exist, which guarantees the quality of welding. When the place of welding is far, the connectable type is adopted, and the welding cable can be added to required length, which has the same effect with the fixed type.
Description
The utility model relates to safe, convenient, energy-saving secondary welding cable--the combined welding cable that the ac/dc electric welding machine of a kind of welding cable, particularly a kind of manual arc is used.
At present, all there are some defectives in the secondary power supply line and the secondary circuit line of the employed welding cable of ac/dc electric welding machine of most of manual electric arc weldings:
1, the secondary power supply of drawing from the output of ac/dc electric welding machine is often long to the power line between the soldering turret:
(1) is deposited in electric welding machine mussily, brokenly to the passage between workpiece;
(2) how much length each welding needs, and pulls out corresponding length by the electric welder;
(3) remainder, often get together agglomerating, even beat strand, the reversing;
(4) or joint is too much or connector status bad (corrosion, dirt, loosening).
2, often out in the cold to the importance of the secondary circuit line (ground wire) of the source of welding current by electric arc, the overwhelming majority is a substitute--waste and old cable.
(1) its cross section and material and used secondary power supply line do not match;
(2) transition joint is many and bad, strikes sparks during welding, sometimes even rubescent;
(3) when length is not enough, often do interim loop with equipment or pipeline.
Thereby, cause a series of problems:
1, because the secondary power supply line can not be decontroled stretchingly fully, and irregular arrangement can cause very big voltage drop, causes impedance loss, increases energy waste.
2, because the secondary circuit line does not match, cause voltage fluctuation bigger, electric current is suddenly big or suddenly small, poor welding quality.
3, electric welder no-load voltage is excessive, and the ground wire defective insulation causes electric shock accidents sometimes.
4, because secondary power supply line and secondary circuit line are two and longer, often beat strand, need untie during welding, stretching, inconvenience because of mixed and disorderly the stacking.
The purpose of this utility model solves above-mentioned existing problems exactly, and a kind of novel combined welding cable is provided, and reaches safe, energy-conservation, easy to operate effect.
The utility model proposes of task is finished as follows: the output of electric welding machine to secondary power supply line between the soldering turret and secondary circuit line, is become a two-wire--fixed welding cable arranged side by side by wrapped with insulation.As a side of power supply, an end is connected on the electrode holders, and the other end is connected to the output of ac/dc electric welding machine; As a side of secondary circuit line, an end is connected to the ground connection piece, and the other end is connected to the secondary circuit of ac/dc electric welding machine.
Like this, it is on-the-spot that ground wire and electrode holders arrive welding synchronously, can avoid substituting with equipment and pipeline the dangerous situation of secondary circuit line.During welding, so structure can guarantee the straight safety of welding cable, does not have the voltage drop that unnecessary impedance loss causes, and has guaranteed welding quality.
If welding distance location electric welding machine is far away, can also adopt mountable welding cable, be two ends with by-pass 1 and 2, the centre pegs graft one to several main lines 3, and still obtains and the same effect of said fixing formula welding cable.
A whole set of combined welding cable is contained on the cable trolley, rotary cable bobbin is housed, in order to twine whole cables on the dolly.During welding, cable can be stretched out also and can partly be wrapped on the bobbin, because queueing discipline can't produce anti-resistance loss.
The combined welding cable that the utility model provides, the welding cable of using with existing ac/dc manual electric arc welding compares, and has tangible advantage:
1, safety--the ground wire insulation of making secondary circuit is good, need not employing equipment or pipeline and makes interim ground wire, and the continued access SI semi-insulation is reliable, and the equipment and the person all can guarantee safety.
2, energy-conservation--during welding, the secondary power supply line draws back and stretches and loop is reliably rationally arranged, and does not have unnecessary anti-resistance loss and the voltage drop that causes, needn't improve voltage, strengthens electric current.
3, welding quality is good--and do not have big voltage drop in the welding process, electric current is basicly stable, and welding quality is guaranteed.
4, reducing labor intensity, increase work efficiency--carrying, shortening or spreading, unwrapping wire, take-up are all very convenient.
