Oil-immersed power transformer assembling forming machine and method

Abstract

The invention provides an oil-immersed power transformer assembling forming machine and method. The oil-immersed power transformer assembling forming machine comprises a joint control mechanism, a floating clamping mechanism and a main frame mechanism. The problems that in the process of clamping silicon steel sheets with clamping pieces, no good clamps for assisting assembly exist, and in the assembling process of an iron core, when upper and lower clamping pieces are respectively assembled with silicon steel sheets, the distance adjustment of the paired upper and lower clamping pieces is a key problem, and due to the strict requirements on the electrical performance of an iron core and the distance tolerance of the paired upper and lower clamping pieces, the fine adjustment of the distance between the paired upper and lower clamping pieces is difficult, the operation is time-consuming and labor-consuming, the assembling process is extremely inconvenient, and adjustment and fixation cannot be conducted according to upper clamping pieces or lower clamping pieces of different models and sizes, so that the production efficiency is low, and the assembling quality cannot be stably guaranteed are solved.

Description

technical field [0001] The invention relates to the technical field of transformer production, in particular to an oil-immersed power transformer assembly molding machine and a molding method. Background technique [0002] The oil-immersed power transformer is one of the important equipment in the power supply and distribution system for industrial and mining enterprises and civil buildings. The oil-immersed transformer adopts a fully oil-filled sealed type. Rely on oil as the cooling medium, such as oil-immersed self-cooling, oil-immersed air-cooled, oil-immersed water-cooled and forced oil circulation, etc. The corrugated oil tank shell adapts to the expansion of oil with its own elasticity and is a permanently sealed oil tank. Oil-immersed transformers have been widely used in various power distribution equipment; [0003] During the assembly and molding process of oil-immersed power transformers, the assembly of the iron core is particularly important. The iron core is ...

AI Technical Summary

Problems solved by technology

[0004] Nowadays, there is no good fixture auxiliary assembly in the process of clamping the silicon steel sheet by the clamp. In the assembly process of the iron core, when the upper and lower clamps are respectively assembled with the silicon steel sheet, the pair of upper clamps or lower clamps Spacing adjustment is a key problem. Due to the requirements of the electrical performance of the iron core, the spacing tolerance requirements of the paired upper or lower clamps are strict, and the fine adjustment of the spacing between the paired upper or lower clamps is difficult and time-consuming. , laborious, the assembly process is extremely inconvenient, and cannot be adjusted and fixed for upper or lower clamps of different sizes, resulting in low production efficiency and unstable assembly quality; therefore, the present invention provides an oil Immersed power transformer assembly molding machine and molding method
