[0037] Specifically, the moving-out assembly is based on the L-shaped support 9, which is stably and fixedly connected to the top right side of the bottom plate 1 to provide support for the whole moving-out assembly. The inside of the L-shaped support 9 is fixedly connected with the hydraulic rod 10, which receives the instructions of the control console 13. When the transformer component is longitudinally cut and transversely clamped in the U-shaped box 3, the output end of the hydraulic rod 10 extends forward to drive the push plate 11 fixedly connected thereto to move forward synchronously, pushing the disassembled transformer component out of the U-shaped box 3 to realize the automatic moving-out of the disassembled component, greatly improving the work efficiency.

The top outside of the longitudinal cutting knife 6 is fixedly connected with a plurality of force distribution rods 16, the top of which is fixedly connected to the outside of the output end of the hydraulic cylinder one 5. When the hydraulic cylinder one 5 pushes the longitudinal cutting knife 6 to cut the transformer component downward, the force distribution rod 16 can evenly distribute the output force of the hydraulic cylinder one 5 to the longitudinal cutting knife 6, so that the longitudinal cutting knife 6 is more evenly stressed during cutting, avoiding damage to the cutting knife due to excessive local stress.
