Abstract

The utility model relates to a current transformer forwelding machine, composed of an opening-shaped core type iron core, a first secondary winding, a clamping component and a wire connection plate. The partial cross section of a core post of the iron core forms a multistage external connection circular shape. The first secondary winding is divided into a plurality of disks from top to bottom. Flat copper wires are winded in the interphase positive and negative directions. Cushion blocks are arranged between the contiguous disks. The utility model has the advantages of reasonable design, compact structure, and simple manufacturing process. The large capacity as far as possible is obtained by the small volume and weight as far as possible. A power supply manufactured by the utility model has small volume, and light weight. The power supply manufactured by the utility model is convenient for moving. The current can be automatically changed following the specification sizes of welded components. The utility model is an ideal matching power supply which is used for butt-welding machines and which is especially used for high-altitude building upright butt-welding machines.

Description

Current transformer forwelding machine

The utility model belongs to the welding equipment technical scope, relates to a kind of power converter of butt welding machine.

At present, butt welding equipment all is the ground flat soldering equipment generally, is difficult to adapt to the requirement of vertical butt welding.The application number that Taishan Machinery Plant, Tai'an City produces is 88219791, name is called the patented product of " portable reinforcing bar submerged arc butt welding machine ", solved the problem of the vertical butt welding in ground preferably, but, this butt welding machine does not have power source special, generally all be that to use 500 type A.C. welders be the source of welding current, the current transformer of this power supply is that a kind of stem stem partial cross section is square, winding be continuously along around common transformer, between winding and iron core stem stem bigger space is arranged, the magnetic consumption is high, and capacity is low, therefore the volume and weight of power supply is all bigger, difficult, especially for high-altitude building vertical type steel-bar to welding, use very inconvenience, and welding current needs to change by manual setting voltage, can not change automatically with welded part specification size.

Task of the present utility model provides a kind of butt welding machine current convertor device, its power volume is dwindled, weight saving, be convenient to move, and under little, the lightweight condition of volume, reduce magnetic loss to greatest extent, the raising capacity, match with existing above-mentioned butt welding machine, to be adapted to vertical butt welding, particularly the high-altitude building is vertical to requirement of welding.

Task of the present utility model is to improve realization on the basis of existing technology, and it comprises " mouth " core formula iron core, two windings of primary and secondary, and folder and terminal block, its main points are that its iron core stem stem partial cross section is multistage external circle.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a vertical view of the present utility model.

Fig. 3 is the A-A cutaway view among Fig. 1.

Below in conjunction with accompanying drawing the utility model is elaborated:

According to Fig. 1, Fig. 2 and shown in Figure 3,6 is " mouth " core formula iron cores among the figure, by directed cold-reduced silicon sheet do magnetic conductor repeatedly dress form, last lower yoke and left and right sides stem stem constitute the widely different road of closed alternation of load magnetic flux, be respectively installed with elementary winding 3 and secondary winding 1 on the stem stem of the left and right sides, clamped by folder 5 and to be one, terminal block 2 is equipped with in the front side.Main points are said " mouth " core formula iron cores 6, the cross section of its stem stem part is multistage external circle, like this, can be under the condition that guarantees the stem stem net sectional area, it is long to shorten winding turns to greatest extent, economize on material, weight reduction, and reduce gap between winding and the stem stem, reduce magnetic loss, the raising capacity, reduced volume; Said primary and secondary winding 3,1 all divides some dishes from top to bottom, and the flat type copper wire coiling of alternate both forward and reverse directions, makes leading-out terminal be positioned at skin, so that wiring; Be provided with cushion block 4 between adjacent disc, its effect one is fixing coiling, the 2nd, can make to form radiating groove between dish, and be convenient to heat radiation, reduce temperature rise.One, three, five of secondary winding 1 ... the tail end of dish is respectively with two, four, six ... the head end of dish links one, three, five ... the head end parallel connection of dish, two, four, six ... the tail end parallel connection of dish as leading-out terminal, is connected on the terminal block 2.

The utility model is reasonable in design, compact conformation, and technique for coiling is simple, with as far as possible little volume and weight, obtain big as far as possible capacity, with the power supply of its making, volume is little, in light weight, be convenient to move, electric current can change automatically with welded part specification size, is butt welding machine, build the supporting power supply of a kind of ideal of vertical butt welding machine especially for the high-altitude, it also can be used as arc welding simultaneously.
