[0004] (1) When the traditional wiring bushing processing and forming equipment is processing the bushing, the blanks in the inner hole of the blank are not close enough, resulting in the quality of the bushing made from the blank being unqualified
[0005] (2) When the traditional wiring bushing processing and forming equipment is processing the bushing, when the finished blank is separated from the equipment, due to the structure of the equipment, the blank is skewed and collided due to uneven force, resulting in the unevenness of the blank. qualified

Embodiment Construction
[0038] In order to make the technical means, creation features, achievement goals and effects realized by the present invention easy to understand and understand, the following combination Figure 1 to Figure 7 , the present invention will be further described.
[0039] A processing and forming method for a power transformer outlet wiring bushing, which uses a wiring bushing processing and forming equipment, the wiring bushing processing and forming equipment comprises a worktable 1, a rotating device 2, a mold device 3, a moving device 4 and a pressing device 5 , the specific method of using the above-mentioned wiring bushing processing and forming equipment to process and shape the wiring bushing is as follows:
[0040] S1. Prepare the blank: mix the required materials and stir them evenly;
[0041] S2, outer contour shaping: pass the blank prepared by S1 into the pressing device 5, and move the mold device 3 to a suitable position through the moving device 4, and shape the...

The invention relates to a method for processing and forming an outlet wiring bushing of a power transformer, which comprises a workbench, a rotating device, a mold device, a moving device and a pressing device. A moving device is installed on the left and right sides of the upper end of the device, and a pressing device is installed on the front end of the rotating device. The device drives the mold device to rotate, so that the blank is filled with the mold by centrifugal force, and at the same time, the inner wall of the blank is pressed by the pressing device. After the blank is processed, the blank is separated from the mold device by the moving device, and fixed by the pressing device blanks to prevent the blanks from being bumped and deformed due to uneven force.
Description
technical field [0001] The invention relates to the field of transformer processing, in particular to a processing and forming method for an outgoing wiring bushing of a power transformer. Background technique [0002] The transformer bushing is an insulating bushing that leads the high and low voltage leads inside the transformer to the outside of the oil tank. It not only acts as the lead to insulate the ground, but also plays the role of fixing the lead. The transformer bushing is one of the current-carrying components of the transformer. , through the load current for a long time, when a short circuit occurs outside the transformer, through the short circuit current, with the development of the national power industry, the casing processing technology is also constantly improving. [0003] In the process of processing the casing, due to the structural limitation of the casing, the following problems exist in the actual operation process: [0004] (1) When the traditiona...
