Tensioning device for transformer coil

Abstract

The invention discloses a tensioning device for transformer coils, which comprises a workbench. A motor is fixedly connected to the outer wall of one side of the workbench through a fixing seat. The end of the shaft away from the motor is rotatably connected to the inner wall of the workbench through bearings, and the middle part of the output shaft runs through and is fixedly connected with the driving wheel. The invention replaces the second transmission belt of a different type, opens the electric telescopic rod, drives the slider to move, and makes the connecting rod move. Drive the upper tension roller at one end of the connecting rod to move, so that the distance between the two upper tension rollers changes, and the tension of the fixed coil original wire between the two upper tension rollers can be changed. By setting the spring and the telescopic column , When the slider moves, the spring on the connected telescopic column is compressed and rebounds, squeezing the slider, so that the force on both ends of the slider is more balanced and stable, and the coil original wire is more stable when it is tensioned, and it is not easy to shift.

Description

technical field [0001] The invention relates to a tensioning device, in particular to a tensioning device for transformer coils, and belongs to the technical field of component processing auxiliary equipment. Background technique [0002] When the transformer is working, it needs a coil to operate. The coil of the transformer has a layer type and a cake type. During the processing of the coil, the copper wire needs to be wound to form a spiral multi-layer coil. During the winding process, it is necessary to Tensioning the coil increases the coil strength after winding. [0003] Under the existing technology, the tensioning device of the transformer coil usually uses tensioning rollers for tensioning and conveying. However, when winding different types of coils, the tension cannot be adjusted. When the tension is too loose, the coil may be too loose to cause The winding effect is poor, and the coil is easy to collapse when the tension is too large. Therefore, in order to sol...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a tensioning device for transformer coils. By setting the upper tension roller, the lower tension roller, the electric telescopic rod and the spring, it effectively solves the problems of the prior art. The medium tension cannot be adjusted. When the tension is too loose, the winding effect may be poor due to the looseness of the coil. When the tension is too large, the coil is easy to collapse.
