A transformer forming insulating cylinder cutting device

technical field

Background technique

The insulating cylinder formed on the inner diameter side of the transformer coil is an important structure to ensure the ability of the product to withstand a sudden short circuit. Since the insulating cylinder directly affects the size of the coil and the coordination between the coils, there are strict requirements on the size of the insulating cylinder. The material of the forming insulation tube is electrical insulation cardboard. Considering the shrinkage of the insulation cardboard after drying, a certain margin will be added during production. There is a rebound phenomenon when the wire is wound, so a process auxiliary cylinder will be added to the forming insulation cylinder (it needs to be made as a whole. In order to facilitate the removal of the process auxiliary cylinder, only 1 to 3 connection points are reserved for the cutting of the division), and the coil winding is completed. Then remove the auxiliary cylinder. The traditional processing method draws a line on the formed insulating cylinder and uses portable electric tools (electric planer, electric drill, jigsaw, etc.) to process. There are three obvious defects: first, the formed insulating cylinder is a cylinder The shape and height of processing are generally marked and planed to size using an electric planer.
