Abstract

The utility model relates to a welding structure of a transformer, comprising multiple iron cores and multiple groups of transformers formed by coils wound on the iron core. The iron core is welded on two ends of the fixed plate of a fixed transformer by adopting argon arc welding; the iron cores wound with coils are close to a middle iron column of the fixed transformer; and the transformer is welded on the fixed plate of the fixed transformer by adopting gas shield welding. Comparing the transformer welding structure provided by the utility model with the conventional transformer welding structure, the conventional transformer welding structure requires a great amount of time and labour during production, and is difficult to control the consistency of the transformer on the technological requirement, therefore, the performance is lowered. By using the processing method provided by the utility model, the labour efficiency and manual operation are greatly reduced and the consistency of the transformer can be controlled better.

Description

A kind of transformer Welding Structure

Technical field

The utility model relates to a kind of Welding Structure, particularly relates to a kind ofly reducing efficiency and manual operation greatly the transformer Welding Structure that also can be well controlled to the consistency of transformer.

Background technology

In present various electrical apparatus industries, all be unable to do without transformer, to industry electrical equipment, all need the transformer buck or boost from household electrical appliances, output voltage that obtains envisioning and output current energy.And big, little the having of these transformers, shape also has nothing in common with each other.Today, what we mainly applied for is the special-purpose main transformer of electric welding machine.This transformer all is indispensable part in the electric welding machine industry, from before A.C. welder, DC welder finally, again to the inverter type welder of today, a main transformer is arranged all.In inverter type welder, this transformer is used for participating in inversion and carries out work such as step-down, and in this process, and the frequency of main transformer work is all very up to 20KH _Z, therefore, this transformer can not adopt common silicon steel sheet to do permeability magnetic material, and adopts the amorphous permeability magnetic material to do iron core, so the inverter type welder main transformer here just is not discussed.And in our the AC and DC welding machine, the core material that main transformer adopts all is a silicon steel sheet.

In our interchange or DC welder, main transformer is most important parts, and the quality that its is made will influence the performance of whole welding machine, and therefore carrying out main transformer is a very important process procedure.

The main transformer of present transformer all will lean on the artificial silicon steel sheet that processes that main transformer is used to divide into groups to fold; Again coil is inserted in; At last whole transformer is intersected and put up; As illustrated in fig. 1 and 2, Fig. 1 is one of welded structural representation of existing transformer, and Fig. 2 is two of the welded structural representation of existing transformer.Lamination 1 per four intersection closed assemblies among Fig. 1 and 2.

The utility model content

To the problems referred to above, the main purpose of the utility model is to provide a kind of can reduce efficiency and manual operation greatly, the transformer Welding Structure that also can be well controlled to the consistency of transformer.

The utility model solves above-mentioned technical problem through following technical proposals: a kind of transformer Welding Structure; Said structure comprises the some groups of transformers of being made up of some iron cores and the coil on iron core; It is characterized in that: said iron core is welded on argon arc welding on two terminations of fixed head of stationary transformer; Be wound with the iron core of coil and the middle iron prop of stationary transformer and closely be close together, transformer adopting gas is protected and is welded on the fixed head of stationary transformer.

In the practical implementation example of the utility model, number scope unshakable in one's determination is 2-4 in the iron core of said one group of transformer.

In a practical implementation example of the utility model, number unshakable in one's determination in the iron core of said one group of transformer is 3.

The positive progressive effect of the utility model is: the transformer Welding Structure that the utility model provides has the following advantages: the transformer Welding Structure that provides through top the utility model and conventional transformer Welding Structure are to recently seeing; The conventional welded making of transformer needs great amount of time and artificial behaviour to do; And on technological requirement, be difficult to the consistency of control transformer, make its decreased performance.And adopt the processing method of the utility model, and reducing efficiency and manual operation so greatly, also can be well controlled to the consistency of transformer.

Description of drawings

Fig. 1 is one of welded structural representation of existing transformer.

Fig. 2 is two of the welded structural representation of existing transformer.

Fig. 3 is the welded structural representation of transformer that the utility model provides.

Embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.

Fig. 3 is the welded structural representation of transformer that the utility model provides; As shown in Figure 3; The utility model comprises by some unshakable in one's determination 2 and some groups of transformers forming of coil on iron core; Said 2 usefulness argon arc weldings unshakable in one's determination are welded on two terminations 4 of fixed head 3 of stationary transformer, and the iron core 2 that is wound with coil closely is close together with middle the iron prop of stationary transformer, and transformer adopting gas the guarantor be welded on the fixed head 3 of stationary transformer.

In the practical implementation example of the utility model, number scope unshakable in one's determination is 2-4 in the iron core of said one group of transformer, and generally selecting number is 3, in concrete application process, can select as required.

More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection range to be defined by appending claims and equivalent thereof.
