Abstract

The utility model discloses an electron impact (EI) iron core transformer frame riveting device. The EI iron core transformer frame riveting device comprises an upper press plate and a lower press plate which can be pushed by a punching machine to perform vertical movement. A spring is arranged between the upper press plate and the lower press plate, two sides of the upper press plate are provided with press blocks for bending the top end of a transformer frame, the bottom ends of the press blocks are provided with press grooves with isosceles trapezoid structures, two waists of each press groove can abut against the top end of the transformer frame. After adopting the structure, due to the fact that upper press plate, the lower press plate and the press blocks for bending the top end of the transformer frame are arranged, the punching machine can push the upper press plate and the lower press plate to press the top end of the transformer frame in installation, then the press blocks are used for bending the top end, the EI iron core transformer frame riveting device is simple in structure and convenient to use, uses the punching machine to drive the upper press plate and the lower press plate to act, reduces manual labor intensity, improves production efficiency and ensures the product quality.

Description

The riveting set of EI appendiron core transformer framework

Technical field

The utility model relates to a kind of structure that the transformer framework is installed, specifically a kind of riveting set of EI appendiron core transformer framework.

Background technology

The installation of existing EI iron core tape frame transformer generally need to be passed through following process, at first carry out the inserted sheet operation, the iron frame of after inserted sheet is finished transformer being packed into, with the iron chains head iron frame is struck tightly again, adopt existing this mounting means, on the one hand, adopt and manually beat iron frame, inefficiency, labor intensive muscle power is many, on the other hand, because everyone technical merit is different, the quality of the product of producing can not guarantee in the process of beaing, again on the one hand, the mode of manually beaing causes injurious surface mark and inner E easily, not driving fit even distortion between the I sheet produce noise behind the dipping lacquer and loss increases, and therefore existing this mounting means needs to improve.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of can enhancing productivity, the riveting set of the EI appendiron core transformer framework that improves the quality of products.

In order to solve the problems of the technologies described above, the riveting set of EI appendiron core transformer framework of the present utility model, comprise and to promote top board and the lower platen move up and down by punch press, be provided with spring between top board and the lower platen, the both sides of top board are provided with the briquetting that can carry out to the top of transformer framework bending, the bottom of briquetting is provided with the indent of isosceles trapezoidal structure, and two waists of indent can be pressed on the top of transformer framework.

After adopting above-mentioned structure, because the upper lower platen that arranges and the briquetting that can carry out to the top of transformer framework bending, can promote the top that upper lower platen is pressed in the transformer framework with punch press during installation, then with briquetting bending is carried out on the top, arrange thus simple in structure, easy to use, move with pressing plate about the punch press drive, reduced artificial labour intensity, improved the efficient of producing, guaranteed the quality of product.

Embodiment

Below in conjunction with the drawings and specific embodiments, the riveting set of EI appendiron core transformer framework of the present utility model is described in further detail.

As shown in the figure, the riveting set of EI appendiron core transformer framework of the present utility model, comprise and to promote top board 1 and the lower platen 2 move up and down by punch press, be provided with spring 3 between top board 1 and the lower platen 2, the both sides of top board 1 are provided with the briquetting 4 that can carry out to the top of transformer framework bending, the bottom of briquetting 4 is provided with the indent 5 of isosceles trapezoidal structure, and two waists of indent 5 can be pressed on the top of transformer framework.

During use, at first transformer is slightly done to pack into after the shaping iron frame of transformer, then transformer is put into riveting tool 6 and carried out push-tight positioning, after finish the location, according to the operation card requirement, start pneumatic punching machine, pneumatic punching machine is pressed on the top board, top board 1 and lower platen 2 are moved downward, and lower platen 2 is pressed over the top 7 of transformer framework, and then pneumatic punching machine continues to promote downwards, the resistance that top board 1 overcomes spring moves downward, the briquetting 4 of top board both sides is moved downward, and at this moment, two waists of the indent 5 of briquetting 4 bottoms are pressed on the top of transformer framework, under the promotion of pneumatic punching machine, just bending can be carried out in the top 7 of transformer framework, by the riveting set of EI appendiron core transformer framework of the present invention is disposable iron core neatly and with framework be riveted tightly thus, easy to use.

Claims

1. the riveting set of an EI appendiron core transformer framework, it is characterized in that: comprise and to promote top board (1) and the lower platen (2) move up and down by punch press, be provided with spring (3) between top board (1) and the lower platen (2), the both sides of described top board (1) are provided with the briquetting (4) that can carry out to the top of transformer framework bending, the bottom of described briquetting (4) is provided with the indent (5) of isosceles trapezoidal structure, and two waists of indent (5) can be pressed on the top of transformer framework.
