Abstract
The invention discloses a kind of transformer core tinertoy piece riveting methods.It includes the following steps：A, by transformer E, the die sinking of I iron cores is made with mutually matched groove and protrusion, and tinertoy is carried out by required thickness in punching press；B, after tinertoy is completed, directly by monoblock E in transformer assembly line, I it is on chip enter skeleton；C, the skeleton for installing iron core is put into riveting device and carries out riveting, rivet tightly E, I pieces up and down during riveting, rivet tightly the mutually locking of rearward recess and protrusion so that EI pieces will not unclamp again after riveting.After the above method, the efficiency for solving intersection inserted sheet is slow, the tension in skeleton window and excessively loose problem that silicon steel sheet thickness change is brought, and solves the problems, such as electric current excessive the problem of causing no-load transformer electric current and loss superelevation and tempering piece to be not easy the to weld when welding of EI pieces, its entire technological process is succinct, manufacture efficiency is very high and assembly precision is high, and there is no silicon steel sheet scrap problems, significantly solve production cost.
Description
Technical field
The present invention relates to a kind of transformer core riveting technology, specifically a kind of transformer core tinertoy piece riveting side
Method.
Background technology
Currently, conventional transformer core tinertoy piece riveting two kinds of production technologies of generally use, a kind of technique is：Per a piece of
Intersect inserted sheet, during inserted sheet, different size silicon steel sheet needs customized different plug-in sheet machines, which to cause transformer bigger, insert
Piece speed is slower, also suffers from the influence of silicon steel sheet thickness and burr, can tightly cause very much last a piece of very laborious, and Tai Song can make again
At becoming larger for no-load current, therefore, is scrapped there is also a certain proportion of using the silicon steel sheet of the process, cause and be produced into
This waste.Another technique is：E, I are first divided into required thickness, and by E, I pieces are welded after being packed into special fixture with argon arc welding
Connect, although this technique is promoted than inserted sheet efficiency, to welding distance and electric current require it is higher, and be tempered piece be not easy to weld
It connects, welding current crosses the superelevation that conference causes no-load transformer electric current and loss, and defective products iron core can only be scrapped, and can equally cause
The waste of production cost.
Invention content
That the technical problem to be solved in the present invention is to provide a kind of production efficiencys is high, performance is good, good product quality and life
Produce transformer core tinertoy piece riveting method at low cost.
In order to solve the above-mentioned technical problem, transformer core tinertoy piece riveting method of the invention, includes the following steps：
A, by transformer E, the die sinking of I iron cores is made with mutually matched groove and protrusion, and required thickness is pressed in punching press
Carry out tinertoy；
B, after tinertoy is completed, directly by monoblock E in transformer assembly line, I it is on chip enter skeleton；
C, the skeleton for installing iron core is put into riveting device and carries out riveting, riveted tightly E, I pieces up and down during riveting, riveting
Next groove and protrusion mutually locking are so that EI pieces will not unclamp again after riveting.
There is the E on pieces groove, the I on pieces to have the protrusion coordinated with groove.
There is the E on pieces protrusion, the I on pieces to have the groove with male cooperation.
In the step C, using pneumatic device by E during riveting, I pieces are riveted tightly up and down.
After adopting with the aforedescribed process, it is clasped setting and carries out riveting by way of tinertoy, need not only intersected
Inserted sheet, the tension in skeleton window and excessively loose problem that the efficiency for solving intersection inserted sheet is slow, and silicon steel sheet thickness change is brought,
Nor need to be welded with argon arc welding, also just solve EI pieces welding when electric current it is excessive cause no-load transformer electric current and
The problem of the problem of superelevation is lost and tempering piece are not easy to weld, in addition, its entire technological process is succinct, manufacture efficiency is very high
And assembly precision is high, there is no silicon steel sheet scrap problems, significantly solve production cost.
Description of the drawings
Fig. 1 is the production procedure artwork of transformer core tinertoy piece riveting method of the present invention.
Specific implementation mode
With reference to the accompanying drawings and detailed description, the transformer core tinertoy piece riveting method of the present invention is made further
It is described in detail.
As shown, the transformer core tinertoy piece riveting method of the present invention, includes the following steps：
A, by transformer E, I iron cores (silicon steel sheet) die sinking is made with mutually matched groove and protrusion, is pressed in punching press
Required thickness carries out tinertoy (as shown in Figure 1, tinertoy agglomerating process step)；
B, after tinertoy is completed, directly by monoblock E in transformer assembly line, I silicon steel sheets are packed into skeleton (as schemed institute
Show, be packed into framework process step)；
C, the skeleton for installing iron core is put into riveting device and carries out riveting, utilize pneumatic device by E, I silicon during riveting
Steel disc is riveted tightly up and down, passes through the side pressing block of left and right sides progress riveting synchronous with the upper holder block positioned at upside, riveting in compaction process
Press consistency good, (as shown, progress riveting processing step) rivets tightly the mutually locking of rearward recess and protrusion and make EI pieces after riveting
It will not unclamp again (as shown, riveting completion processing step).
Wherein, it can both make that there is groove on E silicon steel sheets, there is the protrusion coordinated with groove on I silicon steel sheets, cooperate
Form buckle structure form afterwards, can also when E silicon steel sheets on there is protrusion, there is on I silicon steel sheets the groove with male cooperation,
Buckle structure form is formed after mutual cooperation.
