Abstract
The utility model provides a reversible combined type multiple-head DC welding machine. The utility model comprises a box body unit, machine cores of at least two reversible power supplies independently arranged in the box body unit, and a panel box which is arranged in the box body unit. The output of the panel box is respectively connected with the input of the machine core of each reversible power supply, and the machine core of each reversible power supply is provided with respective positive and negative output connectors. The machine core of each reversible power is independent on the structure, which is conveniently and individually disassembled. The output of the machine core of each reversible power can be individually used, and the output of the machine core of each reversible power can be connected in series or in parallel in order to improve the output voltage or output current of the welding machine. The utility model is suitable for welding needs in different forms.
Description
The utility model relates to a kind of electric welding machine, particularly relates to a kind of inversion combined type bull DC welder.
For adapting to the needs of different Type of Welding, various welding machine is arranged, but mostly be one head arc welding machine, promptly a welding machine has only a pair of positive negative output.Chinese patent CN86204304 has introduced a kind of bull direct current-direct current (AC-DC) welding, be characterized in, the welding head number is 3 N times (N=1～5), power transformer has 3N to organize unidirectional output, but each each transformation into itself's current polarity, the power supply that each group output is the single head AC-dc welding machine welds simultaneously for 3N name welder.The shortcoming of this welding machine is, one, three shared transformer cores of output, between coupling is arranged, its output current and voltage can influence each other.Its two, the welding machine worker is used in the power frequency state, the power consumption, consumptive material, dynamic characteristic is poor.Its three, welding machine when work no-voltage, current feedback, the anti-dried ability of scratching.
The purpose of this utility model is to provide a kind of a plurality of independently inverter movements is fitted together, and multiple welding current and voltage can be provided, the inversion combined type bull DC welder of being convenient to install concentratedly.
The utility model inversion combined type bull DC welder is achieved in that it comprises box unit, independently is placed at least two inverter movements in the box unit, and is arranged on the distribution box in the box unit; The interior inverter movement of box unit is generally 2～4, and distribution box is one, and the output of distribution box connects each inverter movement input respectively, and each inverter movement has positive and negative out splice going splice separately, and promptly this welding machine can provide at least two soldering tips.Be easy installation and removal, box unit is a drawer type, and the inverter movement that is placed in the box unit removably connects with it.When box unit is two or more, use the releasable connection part between box unit, be combined as an overall structure as connections such as bolts, to reduce floor space, can provide more multi-head again simultaneously.For ease of transportation, lifting part can be set on box unit, as suspension ring etc., be convenient to lift by crane with lifting appliance.Wherein, the inverter movement is a prior art, and the panel of each inverter movement is provided with gauge outfit, as voltmeter, ammeter etc., and positive and negative out splice going splice is arranged.
The operation principle of the utility model inversion combined type bull DC welder is, the line voltage that three-phase is 380 volts 50 hertz is sent into the inverter movement through distribution box, in the circuit of inverter movement after the rectification of power frequency three-phase commutation bridge, supply with main controlled inverter, be reverse into midfrequent AC, carry out intermediate frequency transformation and rectification then, obtain output smoothing through filtering and FEEDBACK CONTROL again, and can satisfy welding needs and the DC voltage that can regulate continuously and electric current; Because each inverter movement is independent movement, can be welding machine a plurality of soldering tips are provided, use for a plurality of welders simultaneously, can be used for various welding rods, carry out the manual arc welding, materials such as welding carbon steel, low-alloy steel, high strength steel, stainless steel, cast iron, copper.Also each the inverter movement output in the box unit or between box unit can be connected arbitrarily or/and combination in parallel, when series connection, need to transfer to each inverter movement output current equal, this moment, total output current equaled single inverter movement output current, total output voltage equals each movement output voltage sum, and can be used as cutting power supply etc. has the power supply of bigger needs to use to output voltage.When parallel connection, each inverter movement output current is adjustable respectively, this moment, total output voltage equaled single inverter movement output voltage, total output current equals each inverter movement output current sum, can be used as carbon arc air gouging, submerged-arc welding etc. have bigger needs to welding current power supply.
The advantage of the utility model inversion combined type bull DC welder is on each inverter cassette mechanism structure independent fully, a plurality of soldering tips can be provided, dismantle separately and keep in repair very convenient, each inverter movement output in each box unit or between box unit also can be in parallel or/and series connection, with multiple output current or voltage, adapt to multiple special welding needs, and volume is little, easy to use.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.

Fig. 4: each inverter movement tandem working line schematic diagram in the box unit
The utility model inversion combined type bull DC welder (as shown in Figure 1) comprises two drawer type box unit 1, independently be placed on three inverter movements 2 in the box unit 1 respectively, and be separately positioned on distribution box 3 in the box unit 1, gauge outfit 4 and positive and negative out splice going splice 5 are arranged on the panel of inverter movement 2, be arranged on the suspension ring 6 on the box unit 1, and two box unit 1 are combined into an integrally-built connecting bolt 7.
In each box unit of the utility model inversion combined type bull DC welder, the input of each inverter movement connects distribution box three-phase output, the distribution box three-phase input power supply that gets access to grid.When each inverter movement works alone (as shown in Figure 2), three interior inverter movements of box unit can provide three soldering tips, use simultaneously for three welders; During each inverter movement parallel operation (as shown in Figure 3), the output of each inverter movement is in parallel respectively, can provide three, but can only select the soldering tip of one of them use in box unit; During each inverter movement tandem working (as shown in Figure 4), the output of each inverter movement is connected respectively, and a soldering tip can be provided in box unit.
