The insulation molding barrel is mainly used in the winding to improve the mechanical strength of the winding and improve the short-circuit resistance of the winding. The insulating forming cylinder is made of insulating cardboard. After the forming cylinder is manufactured, during the storage process, because the cardboard is a loose fiber structure, it is easy to absorb moisture and deform the forming cylinder, which affects the use. Therefore, the insulating forming cylinder is immersed in transformer oil after the completion of the manufacturing Prevent the entry of moisture and reduce the deformation of the insulation molding cylinder.

In the prior art, an oil immersion tank (as shown in FIG. 1 ) is used for oil immersion when the insulating molding cylinder is immersed in oil. The oil immersion process when using the oil immersion tank for oil immersion is: put qualified transformer oil in the oil immersion tank, put the insulating molding cylinder into the oil immersion tank, (due to the different diameters of the insulating molding cylinder, the transformer oil in the tank can only Covering a part of the paper tube), the operator stands at both ends of the oil immersion tank and slowly rolls the insulating forming tube to ensure that the insulating forming tube is fully immersed in oil.

Only one insulating cylinder can be immersed in oil at a time when the oil immersion tank is used, and the operator has to rotate the insulating cylinder all the time, which increases the labor intensity of the operator. However, with the increase in the number of insulating cylinders, oil immersion in an oil immersion tank can no longer meet the needs of the production schedule. Therefore, the only way to meet the oil-immersed requirements of the insulating cylinder is to design and manufacture the tooling, and to reduce the labor intensity of the operator.

Utility model content:

A further improvement of the utility model is that the oil tank further includes a tank cover, which is used to seal the top opening of the oil tank.

The further improvement of the utility model is that the oil inlet and outlet pipelines are welded at the lower end of the side wall of the tank body.

The further improvement of the utility model lies in that the suspension pan includes a chassis and a suspension rod arranged on the top of the chassis for lifting the chassis.

The further improvement of the utility model is that the suspension rod includes a suspension ring, a steel pipe and a screw rod, wherein the suspension ring is welded on one end of the steel pipe, and the screw rod is welded on the other end of the steel pipe for threaded connection with the chassis.

The further improvement of the utility model is that a connecting plate is arranged on the circumference of the chassis, and the screw rod and the connecting plate are threadedly connected.

The further improvement of the utility model is that three booms for lifting the chassis are uniformly arranged on the top of the chassis.

A further improvement of the utility model is that the chassis includes a bottom plate and a railing, wherein the railing is arranged on the top of the bottom plate for fixing the insulating molding cylinder.

The further improvement of the utility model lies in that, the bottom of the base plate is further provided with a reinforcing plate, which is used to enhance the strength of the base plate.

Compared with the prior art, the advantages of the oil-immersed tooling described in the utility model are as follows:

1. Improve production efficiency

Due to the different diameters of the insulating forming cylinders, when the insulating forming cylinders are immersed in oil, the small diameter insulating forming cylinders can be placed inside the large diameter insulating forming cylinders, so that many insulating forming cylinders can be placed in the suspension tooling at one time for oil immersion at the same time. Increase productivity.

2. Reduce the labor intensity of the operator

When oil immersion tooling is used for oil immersion, after the insulating forming cylinder is loaded into the hanging pan, the chassis and insulating forming cylinder are hoisted into the oil tank together with the hanger and then oil immersion can be performed, which reduces the labor intensity of the operator.

In summary, the utility model has the advantages of ingenious coordination, simple structure, safety and reliability, and facilitates popularization.
