Method for processing transformer pulling plate magnet isolation tank

Abstract

The invention discloses a method for processing a transformer pulling plate magnet isolation tank, comprising the following processing steps: first, drilling technology holes with diameter being equal to the diameter to the tank width of the magnet isolation tank at the two ends of the X direction of the length of the pulling plate body; aligning the technology holes at one end of the X direction of the length of the pulling plate body with a nozzle of a flame cutting torch along the Y direction of the width of the pulling plate body, a cooling water pipe is arranged along the X direction and at the same line the flame cutting torch is located; the flame cutting torch and the cooling water pipe are connected with a moveable cart at one side of the Y direction of the width of the pulling plate body with two mutually parallel arms; the flame cutting torch is stated to facilitate the moveable cart move along the X direction at a speed of 300-500mm / min towards the technology holes at the other end of the X direction; meanwhile, the cooling water pipe is opened to continuously inject water forward along the movement direction of the flame cutting torch; when the flame cutting torch moves to the technology holes at the other end of the pulling plate; the technology holes at the end is aligned with the nozzle of the flame cutting torch along the outside of the Y direction to facilitate the moveable cart to move in the opposite direction until the cart returns to the previous technology holes.

Description

technical field [0001] The invention relates to a manufacturing method of a transformer pull plate, in particular to a processing method of a magnetic isolation groove of a transformer pull plate which prevents the deformation of cold-worked parts during the processing and affects the use. Background technique [0002] At present, there are two main types of drawing plate structures produced by transformer manufacturers: one is to use multiple narrow steel plates to form a set of drawing plates with magnetic isolation gaps; the other is to use wider steel plates by cutting long lengths between the steel plates. Slot hole (length is generally more than 2500mm, width about 10mm) to achieve the purpose of magnetic isolation. The form of transformer pull plate that cuts long slots between steel plates ( figure 1 ) is also a commonly used structural form in our company. [0003] figure 1 The drawing plate with the structure shown has a small amount of deformation when it is mac...

Problems solved by technology

There is also a method of underwater plasma cutting, but there is a disadvantage that the magnetic isolation groove is easy to be cut or even cut when cutting the magnetic isolation groove underwater

The above defects in the cutting method will directly affect the quality of the drawing plate
