Background technology
In the prior art, the capital equipment that is used for " steel grating " production is " steel-grating press welder ", as shown in Figure 1." steel-grating press welder " is a kind of large-scale powerful electric resistance welding equipment, and its nominal power is between 1000KVA to 1600KVA, and is even bigger.Its production technology is that flat steel bar 9 is arranged width about one meter.Different according to bearing capacity factor measuring and calculating band steel radical, generally between 20mm-40mm, bearing capacity is more big for its spacing, and flat steel bar quantity is more many, and the specification of flat steel bar is more big, yet the bonding power that needs is more big.After flat steel bar is aligned in the personality card hurdle, need pressure welding on flat steel bar (resistance welding technology a kind of) one by one the steel bar 8 of different spacing (also be the twisted string square steel, namely the square steel bar of cold-drawn moulding is twisted into twisted shape), in order to fix and to gain in strength, shown in Fig. 2 a and Fig. 2 b.
Existing press welder, the technical data that the technical parameter that provides according to factory and I measure have at the scene carried out the analyzing total surplus in following defective: 1. volume heaviness; 2. consumed power is big; 3. power factor is low; 4. inefficiency.
Why there is above problem, mainly be because the outmoded backwardness of technology aging, welding current is directly imported by the IGCT gate-controlled switch from electrical network, because welding transformer belongs to inductive load, electric current always lags behind supply voltage and produces the electromagnetism exchange, cause power factor lower, must carry out rectification at the welding transformer outlet side in order to use the three phase mains power supply, strengthened rectifier loss simultaneously.
The utility model content
For solving the problems of the technologies described above, the utility model provides the intermediate frequency of a kind of energy-saving and environmental protection, high-efficiency low-carbon ultralow anti-steel-grating press welder.
The utility model is the ultralow anti-steel-grating press welder of a kind of intermediate frequency, comprise frame, the press oil cylinder, pressure welding power supply, pressure welding electrode, on the described frame slide unit is set, the top electrode mount pad, the flat steel bar support platform, described pressure welding power supply comprises super-low impedance transformer and ultralow frequency inverter controller, the output of described ultralow frequency inverter controller connects the input of super-low impedance transformer, and the output of described super-low impedance transformer connects the pressure welding electrode.
Described ultralow anti-welding transformer adopts the winding construction of many group parallel forms to reduce electrodynamic capacity.
The resistance value of described ultralow anti-welding transformer is less than 10 μ Ω.
Useful technique effect of the present utility model is: adopt advanced pressure welding power technology, the pressure welding power supply comprises super-low impedance transformer and ultralow frequency inverter controller two parts, the reasonable combination of super-low impedance transformer and ultralow frequency inverter controller, therefore make characteristics such as this pressure welding power is big, internal impedance is low, loss is little, efficient height, it is very obvious to be used for its performance after the power supply of steel-grating press welder and superior technical parameter.Compare (when welding same weldment) bonding power with existing type and have only originally 53%, enhance productivity 71%, saves energy 28%-30% is because power factor is near 100%, so need not compensate energy-efficient, environment-friendly and green.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
The utility model is the ultralow anti-steel-grating press welder of a kind of intermediate frequency, comprise frame, the press oil cylinder, pressure welding power supply 3, pressure welding electrode 5, slide unit 2 is set on the described frame, top electrode mount pad 4, flat steel bar support platform 6, described pressure welding power supply comprises super-low impedance transformer 12 and ultralow frequency inverter controller 11, described ultralow frequency inverter controller connects electric network source, realizes the three phase network power supply is become single-phase function.The output of described ultralow frequency inverter controller connects the input of super-low impedance transformer, and the output of described super-low impedance transformer connects pressure welding electrode 5, as shown in Figure 3.Described ultralow anti-welding transformer adopts the winding construction of many group parallel forms to reduce electrodynamic capacity, as shown in Figure 4.The resistance value of described ultralow anti-welding transformer is less than 10 μ Ω.
The ultralow anti-steel-grating press welder of the utility model intermediate frequency has used modern superpower inversion transformation technique, earlier three electric network sources is carried out rectification, because rectifier belongs to resistive load, so its power factor is approximately 100%.Realized that through the power supply behind the three-phase inversion three-phase becomes single-phase function, and need not carry out again rectification later+,-extremely in parallel, thereby greatly reduce the huge loss that brings because of the low-voltage secondary rectification, the realization energy saving purposes.
The utility model adopts ultralow reactance transformer as welding transformer, and it is extremely low to be mainly reflected in its internal resistance, can realize energy-saving and cost-reducing function to the maximized position that concentrates on welded piece of electric energy.The characteristics of ultralow anti-welding transformer are, adopt the winding construction of many group parallel forms to reduce electrodynamic capacity, its internal impedance is extremely low, and it is worth less than 10 μ Ω, and the internal resistance of common power frequency welding transformer is all about 80 μ Ω-120 μ Ω, can not be in contrast to this.Internal resistance is more low, and loss is more little, and the degree of heat is more low, and energy conversion efficiency is more high.Main theory is according to having: 1. XL=2 π f1;
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
