Tension device for transformer coil winding

Abstract

The invention relates to a tension device for transformer coil winding, which is installed between a coil winding machine and a copper conductor drum support. A base is arranged at the lower part of the tension device. The tension device for transformer coil winding is characterized in that a guide rail is arranged at the upper part of the base; a movable guide rail sliding seat is arranged on the guide rail, a roller is arranged on the guide rail sliding seat, and rolling bearings are arranged on the two side surfaces of the guide rail sliding seat to realize the positioning and the movement of the guide rail sliding seat on the guide rail; a pressing device is installed on the guide rail sliding seat, a front supporting roll, a rear supporting roll and a supporting plate of the pressing device are fixedly arranged on a flat panel of the guide rail sliding seat, a front pressing roll, a rear pressing roll and a pressing plate of the pressing device are respectively connected with a front cylinder, a rear cylinder and a main cylinder, and the front cylinder, the rear cylinder and the main cylinder are fixedly arranged on a vertical plate of the pressing device; and the vertical plate of the pressing device, the front cylinder, the rear cylinder, the main cylinder, the front pressing roll, the rear pressing roll and the pressing plate adopt a turnover structure, and the front cylinder, the rear cylinder and the main cylinder are respectively provided with an air path controlled by a pressure gauge and a switch. By adopting a pneumatic pressing method, the tensioning and the squeezing of copper conductors are realized, and the goal of coil compaction is achieved.

Description

technical field [0001] The invention relates to a device for winding and tensioning a coil, which is used in conjunction with a horizontal winding machine in the transformer industry, in particular to a device suitable for winding and tensioning a paper-wrapped flat copper wire coil to realize coil tightening , belonging to the technical field of electrical machinery equipment. Background technique [0002] Since various industries have higher and higher requirements for the manufacturing quality of transformers, especially for coils, in order to improve their short-circuit resistance and other requirements, the coil winding is required to be tight. Among them, the axial direction should be tight, and the radial direction should achieve zero margin. However, due to the characteristics of the coil structure in the existing transformer industry, most of the coils are wound by horizontal winding machines. There are problems that the radial direction of the coil winding is not ...

AI Technical Summary

Problems solved by technology

However, due to the characteristics of the coil structure in the existing transformer industry, most of the coils are wound by horizontal winding machines. There are problems that the radial direction of the coil winding is not solid, the axial direction is not tight, or the cross section of the copper wire is thinned. The reason is that there is no tensioning device, or the tensioning position is incorrect (the wire frame is locked), or the tensioning force is improperly controlled (large or small)
