Description

Transformer oil tank along the shaping tooling

technical field

The invention relates to the technical field of electric equipment manufacturing, in particular to a shaping tool for the edge of a transformer oil tank.

Background technique

A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage regulation (magnetic saturation transformer), etc. According to the purpose, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc.).

Large transformer barrel type oil tank is heavy in weight. After lifting, the edge of the box is squeezed inwardly, which is easy to deform the edge of the box, resulting in the original box edge and the bolt holes drilled in the cover do not match. Although the box edge is supported during the manufacturing process, the fuel tank has been lifted and turned over many times. When the support is removed, the box edge still has a certain deformation, which directly affects the subsequent assembly work.

SUMMARY OF THE INVENTION

In order to solve the above-mentioned technical problems, the present invention discloses a shaping tool for the edge of a transformer oil tank. The bottom side of the bottom plate is welded with a support plate made of steel plate, the support plate is not perpendicular to the bottom plate, the other end of the support plate is welded with a flat plate made of steel plate, and the side of the bottom plate away from the top plate is welded with pins.

In the above technical solution, two pins are inserted on the tooling into the bolt holes along the transformer tank, the wall of the transformer tank and the tooling are supported by a support block, the hydraulic cylinder is used to tighten the transformer tank cover, and the transformer tank is pulled out along the edge. , when the holes are aligned, insert the bolts to fix it.

The further improvement of the present invention also includes a handle, which is welded on the outer side of the bottom plate close to the top plate.

In a further improvement of the present invention, reinforcing ribs are welded between the top plate and the bottom plate. The reinforcing ribs are made of steel bars. One end of the reinforcing ribs is welded to the upper part of the top plate and the other end is welded to the part of the bottom plate close to the handle. more solid.

The further improvement of the present invention also includes a reinforcing plate made of steel plate, the thickness of the reinforcing plate is greater than that of the bottom plate, and the reinforcing plate is welded on the lower part of the bottom plate.

The beneficial effects of the present invention are: because the unilateral size of the bolt holes drilled along the tank edge of the transformer oil tank and the box cover is only reserved for 2mm, the bolts cannot be penetrated if the tank edge is slightly deformed, which can effectively solve the problem that the bolts cannot be installed due to the deformation of the tank edge. question.

Detailed ways

In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

Embodiment: As shown in Figure 1 and Figure 2, a transformer oil tank along the shaping tooling, a transformer oil tank along the shaping tooling, including a base plate 4 made of steel, the upper side of the base plate 4 is welded with a steel plate. The top plate 1, the lower side of the bottom plate 4 is welded with a support plate 7 made of steel plates, the support plate 7 and the bottom plate 4 are not perpendicular, and the other end of the support plate 7 is welded with a flat plate 8 made of steel plates, and the bottom plate 4 is far from the top plate 1. A pin 3 is welded on one side, and a handle 5 is also welded. The handle 5 is welded on the outer side of the bottom plate 4 close to the top plate 1. The setting of the handle 5 can not only be used to carry the tooling, but also can play a role in assisting and fixing the tooling during use. A reinforcing rib 2 is also welded between 1 and the bottom plate 4. The reinforcing rib 2 is made of steel bars. One end of the reinforcing rib 2 is welded to the upper part of the top plate 1 and the other end is welded to the part of the bottom plate 4 near the handle 5. The reinforcing plate 6, the thickness of the reinforcing plate 6 is greater than the thickness of the bottom plate 4, and the reinforcing plate 6 is welded to the lower part of the bottom plate 4.

As shown in Figure 3, the working principle of the embodiment: two pins 3 are inserted into the transformer tank along the bolt holes on the tooling, the wall of the transformer tank and the tooling are supported by a support block, and the transformer tank cover is tightened by a hydraulic cylinder, Pull out the edge of the transformer tank, and when the holes are aligned, insert the bolts to fix it.

The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments.
